Giant breach in earth's Magentosphere

December 25, 2008

If you're wondering why we have had such bad winter storms on the mainland this past week, check out this NASA web page. In the winter, about a week after a major solar flare (X3 on December 11), the continental mainland picks up the "Siberian Express" over the North Pole. That's something that's not observable in Hawaii. Mainland stations get a double whammy, due to the radio disruptions, the winter storm and loss of power.

For a further example, see the correlation between the string of solar flare activity of March 1993 and the March 1993 Storm of the Century blizzard. The added charged solar material interacts with the Earth's magnetosphere, and alters the amount of charged particles ionizing the upper atmosphere. The changing magnetic field affects the ocean currents and moves the jet stream. The altered jet stream brings up warm moist air from the Caribbean and tropics, and brings down cold polar air from the North Pole. These meet up over central North America, bringing intense winter storms and heavy snowfall.

ISS Crossband repeater pass doppler information for Dec 24

December 24, 2008

The ISS passtimes through Jan 5 are calculated and in the following file. See this text file with doppler information for details on the pass.

There is a special crossband mode for Dec 21 through 26. The uplink is 145.99 MHz PL 67.0 Hz, plus/minus 3.3 kHz doppler. The downlink is 437.80 MHz, plus/minus 10 kHz doppler.

ISS Crossband repeater pass doppler information for Dec 21

December 18, 2008

The ISS passtimes through Jan 5 are calculated and in the following file. See this text file with doppler information for details on the pass. There is a special crossband mode for Dec 21 through 26. The uplink is 145.99 with a CTCSS tone of 67.0, and the downlink is 437.80. Check www.issfanclub.com for the latest status. See www.arrl.org for information on the upcoming ISS modes.

The uplink is 145.99 MHz PL 67.0 Hz, plus/minus 3.3 kHz doppler. The downlink is 437.80 MHz, plus/minus 10 kHz doppler.

ISS Crossband repeater pass doppler information for Dec 7

December 7, 2008

The ISS passtimes for tonight, December 7 are calculated and in the following file. See this text file with doppler information for details on the pass. See the next posting for additional details on how to work the ISS. Tonight may be your last chance for quite a while to access the crossband repeater. Check www.issfanclub.com for the latest status.

Honolulu stations, for those of you who've been trying, you're starting to get the proficiency of making a crossband contact. Remember to keep your exchanges very short, as the usable time is probably about a minute or so. These are lower passes at far greater distances than last night, so you'll need more power on the uplink, and a better antenna or receiver on the downlink.

Please listen and allow contacts with Norm, NH7UA who will be trying from Kailua-Kona on the Big Island. His usable passtimes for these passes are about 30-45 seconds later than Honolulu.

The uplink is 437.80 MHz, plus/minus 10 kHz doppler. The downlink is 145.80 MHz, plus/minus 3.3 kHz doppler.

For Norm, NH7UA, doppler pass time for Kona has been included in the second half of the file.

Good Crossband repeater pass of the ISS tonight, Dec 6 8:16 pm, 61 degrees

December 6, 2008

Looks like there will be a nice 61 degree pass starting tonight at 8:16 pm. The ISS should be in crossband repeater mode, and should offer an excellent chance at this rare mode. See this text file with doppler information for details on the pass.

The uplink is 437.80 MHz, plus/minus 10 kHz doppler. The downlink is 145.80 MHz, plus/minus 3.3 kHz doppler. Gary, WH6C remembered that his UHF radio can tune in 5 kHz increments. It is highly recommended to set your UHF radio to do 5 kHz or less tuning increments, and tune for the doppler shift.

Due to the limited amount of time, if you hear solid activity on the crossband repeater, DO NOT call CQ. The usable part of the pass for most stations is perhaps one minute long at most, so we're trying to squeeze as many valid two-way contacts as possible. Just call one of the stations you hear, give your callsign, and give a "59" signal report. For example, if you hear me, just say "AH6RH, KH6XYZ, 59". If I hear you, I would reply "KH6XYZ, AH6RH, 59", and those two transmissions constitute your contact. Remember to share the pass with new stations you hear. You will extend your passtime if you use the 5 and 10 kHz doppler tuning on the uplink. See these pages for more info on working the ISS.

EARC DH 146.88 MHz repeater tuned up

TBX-8 Code Talker Radio on eBay

August 4, 2008, updated Sept 26, 2008

Code talkers were a group of Navaho American Indians that provided secure battlefront communications in the Pacific Theater during World War II. There operations were classified for many years, but have since been declassified and even became material for a Hollywood movie.

Even less is well known about the "portable" tube-based radios they used. This week, eBay has a pristine Garod TBX-8 unit for offer, complete with a hand-cranked generator. If you're into QRP and want to see how it was done in the old days, check it out. It'll make you appreciate your Yaesu FT-817.

See the eBay Website for details.

Update: The Foundation for The National Cryptologic Museum in Ft. Meade, Maryland won the auction and received the shipment, preserving this rare beauty for future generations to learn the story of the Navaho Code Talkers. See the NCM Foundation Website for details.

September EARC General Meeting Presentation

September 6, 2008, updated September 26, 2008

The topic for the September 2008 EARC General Membership meeting is on how to get on HF if you're a Technician class licensee. A number of our members hold the Technician class, and have not gotten on the air with their own equipment. This session steps you through the kinds of equipment to acquire, how to assemble and configure the station, and how to make that first HF contact.

The presentation will also finish up on operational details on making contact with Richard Garriott, W5KWQ, the sixth space tourist that will be in orbit in mid-October.

See the EARC Website for details.

P.s. Thanks guys for letting me know you read these web pages. At least I know my time is being put to good use.

REACT SOS Drill on October 18, 2008

May 22, 2008, updated Sept 10, 2008

Members of the local REACT chapter came to the EARC meeting to inform and partner with us on a upcoming communications exercise entitled REACT SOS Drill scheduled for September 6, 2008 from 10:00 am to 12 noon.

The goal is to have the general public equipped and educated on using Family Radio Service (FRS) radios tuned to FRS Channel 13 (no CTCSS or PL tone) as a means of communicating in the event of a local disaster. Rob, KH7MW presented details at the August EARC meeting. If you establish contact with a person on Channel 13, log the time, exchange your first name, your location (cross street intersection, which floor of a building if you're in a building, or mobile) A hot wash meeting is scheduled for Maryknoll High School on Monday, Sept 8. Click on this link to get to the Honolulu REACT web site. Click on this link to get to the National SOS project web site.

Update: Five REACT members, ten ham radio operators, and one other person participated. One of the lessons learned from this event is that a stock FRS radio can communicate two or more miles. A surprising two-way contact was from Richardson Field near the Aloha stadium, to lower Mililani and the Mililani area.

Based on the success of the Project SOS event in Honolulu, the Honolulu REACT will hold another Project SOS event on Saturday, October 18, 2008 from 10:00 am to 12 noon, on FRS Channel 1. Amateur Radio operators are encouraged to monitor FRS Channel 1 and participate, and pass along summary information as SET (Simulated Emergency Test) messages that morning. Future details forthcoming.

Hawaii QSO Party, Aug 22-24, 2008

August 4, 2008

The Koolau Amateur Radio Club is sponsoring the Hawaii QSO Party on the weekend of August 22. The event is intended to put Hawaii stations on HF to allow those wishing to make a Hawaii contact an opportunity to do so.

See the KARC Website for details.

Many thanks to Richard LaChance, WH6T ex-AH6IO, SK who started the QSO party years ago. Richard was very enthusiastic about amateur radio, operating a lot of DX, hosting license testing sessions, operating from a number of DX locations throughout the Pacific. He is sorely missed.

Increased HF propagation

August 4, 2008

Ernie, NH7L reports on Saturday night of slightly increased HF propagation and is hopeful that solar activity is on the rise. (Of course, with the sunspots gone, almost anything is an increase in HF propagation.) The mobile/portable stations are working Europe and other locales on 20m.

"Eran and Martin have been working dozens of Europeans from Lapland to Bulgaria, plus European Russians, night after night lately with big (33-foot) verticals at Waimanalo Beach. Not just on CW but also on SSB. Tonight I worked SSB stations in Wales and southern England with a small parked mobile vertical. Heard Italians but they didn't hear me. These were the first Europeans I've worked on SSB in a year or longer ... maybe as long as two years. Granted, I haven't had much time for radio for at least the last year, so that may not mean much. Tonight's solar numbers: flux 66, A = 2, K = 1. Yet 20 meters was humming from about 4:30 p.m., when I was hearing East Coast stations real well, until 9 p.m. when I shut down."

"Jim in Rarotonga, E51JD, was telling somebody tonight that for the longest time, conditions were miserable down there. Some days he could hear almost nothing, not even VKs and ZLs. For the last few weeks, though, he said, he's been working the world again. But it's not consistent from day to day, he said."

Oahu 6m and 2m SSB Activity

August 4, 2008

The activity on 6m and 2m SSB continues to grow. On Saturday August 2, 12 stations checked into 50.125 MHz after the 9:00 am Healthcomm net. Newcomers include Sam, KH6BTV, Wayne, KH6MEI and George, AH6GK. Yaesu FT-817's and FT-857D's were predominant in the mix.

Activity then shifted to 144.200 MHz for a short roundtable. Among the radios that were put on the air include the Kenwood TS-700A, Icom IC-202S and Kenwood TR-751A.

That evening, Wayne KH6MEI, Cedric WH7JI and Ron AH6RH further tested Wayne's SSB capability. Wayne and Cedric are able to hear each other faintly, but not enough to make out the conversation. Wayne is located in Salt Lake and Cedric is in Lanai City.

A test on Sunday evening between Malcolm, Ron and Cedric was able to verify CW configuration and transmit operation from AH6RH and CW receive operation at KH6MSH and WH7JI.

August EARC General Meeting Presentation

July 27, 2008

Two Meter Oahu-Lanai 2m Simplex contacts

July 18, 2008

Cedric, WH7JI made two meter simplex contact between Lanai City and Oahu this past week. On Saturday, July 13 at 9:03 pm local, Cedric and Ron, AH6RH made a 2m SSB contact on 144.200 MHz. Cedric ran a Yaesu FT-897D into a vertical, both with a linear amp and without. Signal strength was S0 to S3 at Kapiolani Community College. Signal strength improved up to S9 along stretches of the road leading to the Kaimuki Fire Station. Ron ran an Icom IC-910H running 100 watts into a Diamond NR73BNMO mag mount.

On Sunday, July 14, contact was reestablished on SSB. Operations shifted to 146.52 MHz FM simplex, where an S3 contact was established.

Cedric reports being able to hear Eric WH7JE and Malcolm KH6MSH very faintly from Oahu, but was unable to make two-way contact. Norm, NH7UA expressed interest in making contact from Waimea or Kohala Coast. Randy KH6IB was also heard active on 144.200 on Oahu on Thursday, July 18.

Ron talked of emailing Ruckdee Chotjinda, E20JLS from the Nikon email reflector many years ago, and watching Bill McArthur, KC5ACR autograph the QSL card of a Thai ham at Dayton Hamvention 2007. Jim and Bev have a photo album here.

Thida put together a video of the KARC-EARC Field Day activities, which is visible on YouTube. Hank KH6HAK's public service announcement on KITV can be seen on YouTube.

EARC Educational Workshop on Direction Finding

June 19, 2008

The EARC invites you to an education workshop Saturday, June 21 at the Kapiolani Community College Campus from 9:00 am to 12 noon featuring a workshop on Direction Finding and VHF propagation techniques. This is a follow-on to the presentation at the EARC May General Membership meeting on DF'ing by Ron, AH6RH, which was well received.

The presenters for this workshop are Ron, AH6RH and Bev, AH6NF. The topic is expanded from the core talk on DF'ing to include related topics: a review of VHF propagation (to give adequate discussion of the effects of Oahu's terrain and urbanization), the use of maps for plotting readings, strategies for effective DF'ing and anecdotes on past DF'ing activities. Time will be set aside to demonstrate and interact with DF'ing equipment.

Many thanks to Eric Ty, WH7JE for making the room available. Click here for a map of the campus. The talk-in frequency is 146.88- MHz.

Dean, KH6DT and Kris, WH6OV maintained amateur radio contact while maritime mobile this afternoon on the SuperFerry as it left Honolulu Harbor at 3:00 pm. Contact was established on 444.35+, and maintained for about 23 minutes into the Molokai Channel, at an estimated distance of seven miles into the channel. One of the radios used was the Standard C508 handheld running 1/4 watt into a Diamond SRH-519 operating in the middle of the passenger cabin. The contact ended at 3:38 pm.

Makani Pahili 2008 Exercise Results

May 25, 2008, updated May 26, 2008

On Wednesday, May 21, 2008, amateur radio operators with the Hawaii State CD RACES program operated the KH6HPZ station at SCD EOC in Birkheimer Tunnel within Diamond Head crater from 10:00 am to 2:00 pm, in conjunction and support of the annual Makani Pahili hurricane exercise. On Saturday, May 23 from 9:00 am to 11:30 am, the amateur radio community, HSCD RACES and Pacific Section ARES participated in a communications exercise simulating the recovery from the exercise hurricane, organized by Pacific SEC Kevin Bogan, AH6QO.

We had a total of six amateur radio operators at State CD, plus amateur radio operators on all major islands. Over 25 stations were on HF, including Red Cross, County EOCs at Maui and Hilo, and individuals at homes and other locations were operating on 7.088, 7.080 and 3.9935 MHz. Another dozen were on the state-wide VHF Repeater system.

This year featured a major push to implement and test the use of the NIMS (National Incident Management System) ICS-213 message form. It was used for the first time in Hawaii and the majority of the messages were exchanged in ICS 213 format. This may have been one of the first amateur radio exercise in the nation featuring extensive use of unmodified ICS-213 message forms for formal radio message handling. Given this was the first time, the use of the form and message handling protocol worked reasonably well. The advantanges of the form were it required little training, could be picked up quickly by new operators, the ICS-213 format clearly notes the sender and the intended receiver of the message, and the received message could be given to another person for subsequent handling. During the Wednesday exercise, incoming messages were entered into the EOC email system for handling by the EOC staff as part of the exercise simulation.

The ICS-213 radio forms used for this exercise were the standard form as issued by the US Government Printing Office. Since the original form was designed for use within an EOC and not intended to be used for radio messaging, during this exercise it quickly became apparent that adjustments were needed such as noting the operator position (HF vs VHF), inbound vs outbound message, date/time received or sent, the message number and the name of the operator handling the message were required. The information was written in the margins, and the revised forms have been reposted on the web. This version does not include a word count check, and it is unclear if a count is needed if the communications channels are clear and the operators are proficient.

Termites, HF DX'ing in Hawaii, 10 meters and South Africa

May 22, 2008, updated May 25, 2008

At tonight's EARC General Membership Meeting about Direction Finding, termites started to fly around the room at about 7:20 pm (Thursday, May 22, 2008). The old timers in Hawaii have a saying. "When the termites fly, head to Magic Island and ten meters will be open to South Africa." I couldn't leave the meeting, as I had the presentation to make, but 20 meters was open tonight, with various SSB and CW spots of KH6 from about 8:00 pm to 10:30 pm local time, including KH6ND and KH6XS. Ten was probably open too, even at the bottom of the sunspot cycle.

So, for about the next week, tune around 17, 15, 12 and 10 meters between 7:00 pm and 10:00 pm Hawaii Standard Time (0500z to 0800z). You just might hear and work DX signals.

Update: On the evening of Friday, May 23, I mobiled out and heard a lot of stations on CW for the WPX CW contest. Heard KH6ZM working 10m CW. Did not have a chance to work the bands as I encountered equipment problems, but will try again.

Update2: On Saturday evening, May 24, a number of stations were heard on 40, 20, 17 CW, as well as some SSB. Just because it's the bottom of the sunspot cycle, it doesn't mean that the bands aren't open. They are. You just need to work the bands and make contact.

EARC Direction Finding workshop, Sat June 21 9:00 am - 12 noon

May 22, 2008

As a follow-up to tonight's EARC General Membership Meeting about Direction Finding, an EARC educational workshop will be held on Saturday, June 21, 2008, from 9:00 am to 12 noon at the Kapiolani Community College Campus right behind Diamond Head. Featured will be more detailed discussion on VHF simplex communications, and equipment demonstrations for direction finding.

In the meantime, practice your VHF simplex communication, to better understand how VHF signals behave (or misbehave).

AH6RH and AH6NF work goat mobile/portable station, N0TU atop Mt. Herman, Colorado

May 19, 2008, updated May 20, 2008

Amateur radio operators Ron, AH6RH and Bev, AH6NF at the beach in Mokuleia made contact with Steve, N0TU atop Mt. Herman, Colorado on Saturday, May 17, 2008 on 20 meters. Steve was running a Yaesu FT-817 on only 5 watts at the very bottom of the sunspot cycle. There were only three sunspots, and a sunspot number of 23, so the contact was quite exceptional. It was also unusual because Steve's equipment was hauled to the top of the mountain via two goats! Click here to see Steve's YouTube video of the contact.

Ron and Bev were running a Yaesu FT-817 radio, into a Tokyo Hy-Power HL-50B amp and LDG Z-100 auto-tuner running 50 watts into an Ironhorse 20 meter vertical antenna mounted onto an Alpha Delta tripod, powered by a 33 amp gel cel wheelchair battery. Steve was running a Yaesu FT-817 radio, into a Buddipole antenna, powered by a 7-amp gel cel that he had the goats carry up the slope, along with the rest of his radio equipment. (Great idea, as a 7-amp gel cell is pretty heavy to carry in a backpack.)

May 13, 2008

Amateur radio operators are requested to keep clear from frequencies 14.270, 7.050 and 7.060 Megahertz in order to keep the frequency clear for radio operations regarding the emergency in China due to the recent earthquake.

Look Ma! Europe, and with no sunspots!

April 30, 2008, updated May 2, 2008

Even at the bottom of the sunspot cycle, with zero sunspots on the surface of the sun, it's possible to work Europe from Hawaii. Ron, AH6RH tipped off Bev, AH6NF that there might be an opening on Monday or Tuesday of this week. A satellite had detected a burst of X-rays on 1408z on Apr 26, followed by a CME (Coronal Mass Ejection). NASA's twin STEREO satellites recorded a million mph particle wave spreading from the sun.

Bev tuned up on 20 meters on Apr 30, 0640z to 0815z (Tuesday, April 29 8:40 to 10:15 pm HST) and scored a nice pile-up with Europe. Bev got 75 European QSOs, 21 European countries (Scotland and Estonia were new for Bev) and was spotted 7 times. Bev noted that the band faded out just as if someone had turned off a light switch.

Another opening occurred the next night, from May 1, 0630-0745z (Wed, Apr 30 8:30-9:45 pm HST). Bev, AH6NF worked Europe during the opening. Randy, KH6IB and Bill KH7XS also had pile-ups. Bev talked with Roger, DL5RBW who noted that propagation to the Pacific has been poor the past month, until the past two evenings.

Eran, WH6R reports that he and Martin Barr, KH6MB worked several hundred European stations on 20 meters CW and 20 meters SSB to Ukraine on 100 watts that evening with a end-fed vertical ten feet from the ocean. They were active from 7:30 pm to 10:00 pm local.

On the evening of May 2, the opening to Europe had closed. Ron, AH6RH heard South Africa and China, and wound up working one UA0 for the evening. A solar wind from a coronal hole is scheduled to arrive around May 5.

Even if the solar indexes suck, a nice CME can make your day (or evening)! Stay on your toes, and you just might score another opening and a pile-up! Monitor www.spaceweather.com for more timely updates.

State-wide RACES VHF Repeaters now connected with Kauai

March 19, 2008, Updated March 28, 2008

The state-wide link for the SCD RACES VHF repeater system has been restored to Kauai. It's been many years since the repeater and link has been restored. Many thanks to Robin, AH6CP for pulling together the project team to reconnect the system.

The double beep heard on the Kauai 147.04 repeater indicates that it requires attention for adjustments or repairs. Repairs will take a while.

The Diamond Head 147.06 repeater has been running substantially reduced power output since March 12. Repairs will take a while.

EARC meeting tonight was a huge success!

January 24, 2008

The first EARC General Membership meeting tonight was a huge success. The most lively ham radio club meeting I've been to in years. About 40 people were in attendance. Our president, Wayne KH6MEI opened it with updates and information from the various committees. After the break, Chuck NH7XL gave a short presentation on PSK-31 on 40 meters. After that, it was the swap-and-shop time, trading/buying/giving all kind of stuff and people breaking up into groups of two or three, mingling and talking about all kinds of ham and non-ham items. Very lively conversation. We had guest Cedric, WH7JI from Lanai City at the meeting. If you weren't there, you missed out! Next month's meeting will be at the Red Cross Headquarters on Diamond Head Road.

Rare chance to participate in a 40 meter EME experiment

January 17, 2008, Updated: January 19, 2008

The HAARP research project in Alaska is conducting an unusual lunar experiment, bouncing 40 meter signals off the moon to an receiving array in New Mexico. Operating times are Jan 18 from 7:00 - 9:00 pm HST and Jan 19 8:30 - 10:30 pm HST. See ARRL Bulletin ARLX002 for details.

I filed this report for operations on Friday evening.

Copied the HAARP array direct on 6792.5 and 7407.5. Signal was about S6 on the 6.7 Mhz freq, and around S1 on the 7.4 Mhz freq. Could not copy the EME bounce.

Rig is Icom IC-706 MK II G, without antenna tuner. Narrow 500 Hz filter used. Antenna was random wire antenna, about 35 feet up 12 feet -- in a random pattern. DSP Noise filter is the Clearspeech filter. The HAARP signal could be heard direct on 22 inches of antenna!

Rick, KH7O reports unable to copy the moonbounce echo due to S9 noise.

Other reports from the west side of the Big Island for operations on Friday evening.

Eric, KH6CQ reports S9 up, S3 down, on 40 meter dipole up 10 feet.

Roland, AH6RR reports S9+10dB up, S4-7 down, on Double Bazooka up 30 feet.

Norm, NH7UA reports S6-7 up, -10dB down, on 160m half-wave doublet up 20 feet.

Eric, KH6CQ filed this report from Waikoloa.

Aloha,

My station is located in Waikoloa Village which is on the northwest coast of the big island of Hawaii. I am using a Kenwood TS-850S transceiver and a half wavelength 40 meter dipole antenna which is 10 feet above ground level.

At 0500Z the moon was about 70 degrees above the eastern horizon.

Between 0500 and 0600 on 6.7925 MHz I could hear both the transmitted signal and the reflected signal. I presume the stronger one was the one you were transmitting and the weaker one was the reflection from the moon. During the hour I heard the weaker signal about 90 percent of the time and it was just above my noise level with the exception that at 0546 it peaked at S3. I noticed a brief pause in transmitting about 0530.

Time Strong Signal Noise Level
0500 S9 S5
0515 S9 + 10 dB S5
0530 S9 + 10 dB S5
0545 S9 + 10 dB S2
0559 S9 + 10 dB S1

Between 0600 and 0700 on 7.4075 MHz I also could hear both signals. I heard the weaker signal about 50 percent of the time. The weaker signal started at S1, climbed to S3 by 0630, dropped to S2 by 0645 and was barely heard at the end of transmission due to interference from a shortwave broadcaster with a signal strength between S2 and S3. I noticed about a 30 second pause in transmitting about 0629. There was more fading on the stronger signal at this frequency than the previous one.

Time Strong Signal Noise Level
0600 S9 S1
0615 S7 S1
0630 S9 S1
0645 S6 S1
0659 S9 S1

At 0700 the moon was directly over head.

Details on Roland's report

I received the HAARP test on 6.792.5 MHz. Transmit was S9+10db. Lunar Bounce was S4-7 with flutter at times my noise was S3-5. I did not listen on the second test. It seems that the bounce signal was about a 3 to 4 sec delay and would be in with the transmit signal than following so if your GC was not on a faster recovery time you might have missed the lunar bounce with a strong transmit signal. Antenna is a Double Bazooka @ 30ft and the Radio is a Kenwood TS-850S with Inrad filters. Roland Spoon AH6RR

2008, the year of the ICS-213 form!

January 12, 2008

The ICS-213 message form is the standard message form used by emergency management agencies during emergencies. 2008 is the year that emergency communitors in Hawaii will be pressing to practice and become proficient in handling the ICS-213 form on the air. The goal is to use that proficiency for the October 2008 SET. See the next item for details on how to pass the ICS-213 form on the air.

The last day of the ANDE satellite, NO-61

Updated December 25, 2007

The ANDE satellite has de-orbited.

  • The last packet received at 22:27:08z December 24, 2007 by JA0CAW, and audio is available at the ANDE de-orbit website.
  • The last received packet on the global APRS network was at 21:14:11z December 24, 2007 by W6MSU. "W5MSU]APRS,ANDE-1*,qAO,W6MSU-3:=3803.21NS12121.62W&" It was received in California.
  • About 20 minutes earlier in Japan, JA6PL captured a packet.
  • A little more than an hour prior, WA4AEJ had captured packets in Niceville, FL.

You can see the internal Side A battery temperature rise as the telemetry is captured real-time by amateur radio stations around the world. The rise started at approximately 12:00z on Dec 24, so ANDE lasted only about another 12 hours.

The final altitude prior to the descent may have been 94.65 statute miles or lower, as calculated by keplerian elements only 16 minutes old.

The ANDE satellite lasted one year, three days, four hours in space, having been released at an altitude of 216 statue miles on 18:22z on December 21, 2006 by the Space Shuttle Discovery, mission STS-116 while over the South Pacific. It exceeded the estimated mission life of nine months.

ANDE Ground Operations a success

November 25, 2007

On the November 23, 14:49:00z (November 23, 4:49 am HST) pass, ground station AH6RH finally turned on the laser beacons of the ANDE satellite.

The command sequence for Side A started at 14:48:40z and took 20 seconds, but by that time, ANDE had moved from it's closest approach (elevation of 74 degrees, azimuth bearing of 226 degrees, range of 158 statute miles, RX doppler of 92 Hertz) to a new postion (elevation of 55 degrees, azimuth bearing of 165 degrees, range of 184 statute miles, RX doppler of -1,840 Hertz) which is just about the edge of the effective beamwidth.

Success was finally achieved by pinging the satellite awake about two minutes earlier using a 2kHz offset for doppler, then swinging the Arrow antenna to point to the middle of the pass. ANDE was so low (altitude of 152 miles), and moving way faster than the usual 9 minute, 30 second passes for the ISS (altitude of 220 miles), that it is now only 8 minutes horizon-to-horizon for good passes. Doppler was +/-3.5 kHz for the pass, which was descending east of Oahu.

Power output was about 50 watts from the Icom IC-910H, into a two element Arrow antenna (the director was removed to increase beamwidth). No receiver pre-amp was used. Received signal was at least half-scale during the pass, so the automated logon sequence was used. The logon, commands and disconnect sequenced flawlessly for the first time. Time permitted only the high telemetry and laser beacon enabled commands for Side A to be entered.

First 2304 MHz EME contact from Hawaii

April 24, 2007

Bruce Clark, K0YW, operating KH7X at KH6YY made the first successful EME contact from Hawaii on 2304 MHz at 2:39Z, 23-APR-2007 (Sunday afternoon, 4:39 pm). This is the first time EME from Hawaii has been worked on this band.

Contact was with Al, W5LUA, running 200 watts into a 12 foot TVRO dish. Equipment included an SSB Electronics transverter, a preamp and a Kenwood TS-2000 on 144 Mhz.

Location was the KH7X station at Alex Benton KH6YY's QTH. A number of hams helped Bruce with his attempt. They included KH6YY, KH6ND, KH7U, WH6GS, AH6NF and AH6RH.

2.3 GHz is the near the same frequency band as Wi-Fi wireless PC networking, and residential microwave ovens. Typical Wi-Fi devices are less than 200 milliwatts, and household microwave ovens are 1,000 watts or less. This attempt used more than 1,000 times the normal output of a Wi-Fi device, and about 1/5 the power of a household microwave oven.

Operations was in a tent pitched next to the TVRO dish to reduce feedline losses. The TX feedline was 7/8-inch heliax, and RX feedline included LMR-400 and LMR-600. Noise caused by rain falling on the tent can overwhelm the audio from the radio and disrupt QSOs.

The CW signal was just above the noise level, and sounded "watery" as if the speaker was being held underwater. The warbling tone was much worse than arctic flutter. The sound was typical due to the RF signal reflecting off the irregular surface of the moon. Doppler was on the order of a 3 kHz shift due to the relative motion of the earth and moon, multiplied by the frequency. CW speed was about 13 WPM, with much of the QSO sent twice in short phrases due to the signals being just above the noise level.

First contact with Charles Simonyi, KE7KDP aboard the ISS

April 24, 2007

Ron, AH6RH made the first contact in the world with space tourist Charles Simonyi, KE7KDP while he was passing over Hawaii aboard the International Space Station. The contact occured at 04/11/2007 04:25z.

A female voice announcing "November Alpha One...Sierra Sierra" came on. Ron held a conversation with Suni Williams KD5PLB. Then Suni said "I have a person who wants to talk with you." After a few moments, Charles came on. I welcomed him to amateur radio, and was glad to make contact with him. He mentioned he was thrilled to make contact with Hawaii. I asked him if he was the author of the "Hungarian (variable naming convention)" used in Windows programming which I had done over 20 years ago, and he chuckled as he commented that he was and that others had used and abused the notation. I commented that it was great to meet the creator of the notation.

WH6PN ARISS Telebridge Contact between India and the ISS

February 24, 2007

The ARISS ground station at Sacred Hearts Academy, WH6PN, held an ARISS Telebridge Contact between Vasant Valley School, Vasant Kunj, New Delhi, India and the ISS on Feb 23, 2007 10:50 pm HST. Click the above link for details.

The pass was a 79 degree descending pass. Start was 22:50:47 at 319 degrees; max was 22:55:37 at 228 degrees, 79 degree elevation; end was 23:00:21 at 143 degrees.

A partial audio clip of the downlink (recorded on a vertical antenna) is at: Click here to listen

The astronaut is Suni Williams, KD5PLB. She's responding to these questions:

  • If a gold fish is taken up to a microgravity environment how will the fish react to the lack of gravity as it already floats in a fish tank?
  • What happens to the respiratory gases that are released and remain inside the ISS (like CO2)?
  • Why do some planets have rings?
  • What happens to a bullet fired in space?
  • What kinds of activities are you carrying out? How will they be beneficial to mankind?
  • We are told that resources are highly limited in the ISS. How do you go about this difficulty for example: How much water are you carrying and is there any facility of reusing it over and over again?
  • What kind of food you eat in the ISS and with what frequency?

Double satellite hop contact attempted

January 14, 2007

Ron, AH6RH attempted a double satellite hop between Hawaii and California. AH6RH sent packet messages from Oahu, to the ANDE satellite orbiting about 200 miles overhead. ANDe relayed the message to the PCSAT satellite over the North Pacific to Scott, WA6LIE in Monterey, California. The attempt occured at 01/14/2007 01:09:47z. PCSAT-1 did not hear and digipeat the packets from ANDE-1. Later during the pass, contact was made directly through PCSAT with both Scott and Jim, W7XZ.

December 20, 2006, January 11, 2007

Four new amateur radio satellites have been released. See: RAFT and ANDE Operations Page

The latest keplerian elements can be obtained from here. The ANDE satellite is labelled as #29664, "ANDE (NO-61)". See: Daily keps

The downlink packets and telemetry can be observed here: Igate traffic

Hawaii is serving as ground stations for telemetry and control for the effort.

Here are some reports from RAFT and ANDE See: issfanclub.com

ANDE's two watt transmitter makes clean reception of ANDE difficult. Even with a 3 element beam, the pass has to higher than 80 degrees or more before a Kantronics KPC-3+ can decode the audio into data.

This is the weekend for PCSAT operations

January 9, 2007

The NO-44 PCSAT satellite is usable for about another week. As a result, there's two good passes this weekend to contact the West Coast via PCSAT. Sometime next week, the satellite will fall into the earth's shadow, and reset. When that happens, the digipeating operation will stop. See: The PCSAT web page

The digipeating frequency is 145.825 MHz. The callsign is PCSAT-1. The alternate aliases are: ARISS, WIDEn-n, APRSAT.

The passtimes for Honolulu in HST are:

  • Start: Sat Jan 13 3:07:14 PM @ bearing 006 degrees
  • Middle: Sat Jan 13 3:13:27 PM @ elevation 12 degrees, bearing 059 degrees
  • End: Sat Jan 13 3:18:56 PM
  • LOS: Sat Jan 13 3:19:36 PM @ bearing 112 degrees.
  • Maximum duration: 11 mins 42 secs
  • Start: Sun Jan 14 2:38:00 PM @ bearing 013 degrees

Hams respond to Kiholo Earthquake

October 16, 2006

Amateur radio operators responded to the needs around the Kona Coast area following the magnitude 6.7 earthquake. ARES and RACES operators responded to State and Oahu Civil Defense. See: Kiholo Quake

www.arrl.org

MAKE SURE YOU HAVE A PORTABLE AM/FM RADIO WITH EXTRA BATTERIES, OR ONE THAT HAS AN INTERNAL HAND-CRANKED GENERATOR!

See: www.arrl.org

A reminder: Being prepared is a personal responsibility. Being aware of emergency response and recovery procedures before an incident is also a personal responsibility.

A second reminder: During an emergency, emergency responders use the regular phone lines to activate and coordinate a response, especially between agencies. Nothing is more frustrating to a responder than to get no open phone lines, busy cell phone networks and busy signals -- it slows down their response. So do yourself a favor and keep the phone lines clear! Make ONE call to a relative on the mainland, let them know you're okay, and tell them to call the other relatives on the mainland. That frees up the phone lines for local emergency response.

A third reminder: At the exact moment a disaster occurs, assume everything is broken. What the responders are doing is building a response. If things are working, that's one less headache and the response is one step closer. If its broken, it'll be fixed in priority order. If people, equipment or materials need to be moved as part of that response, especially from a warehouse or staging center to the scene of the response, recognize that it takes some time. In the meantime, improvise.

D-STAR Digital Voice Contact -- Oahu to Maui

August 10, 2006

KH6DT and AH6RH established a Hawaii terrestrial record for digital voice contact using Icom ID-1 D-STAR radios on Thursday, August 10, 2006 at 6:31 pm between Oahu and Maui. Analog voice contact quality was fair, with lots of background noise. The digital voice contact was very clear, but had the "Donald Duck" characteristic and artifact of Icom's D-STAR digital voice quality.

ISS Cross-band Repeater QSOs, Sat June 24, 2006

June 24, 2006

Four way QSO with Bev AH6NF (at the KH6J Field Day site at Kualoa Beach Park, NW side of Oahu), Dean KH6DT (Wailuku, Maui), Ray NH6RZ (Mililani, Oahu), and Ron AH6RH (Ala Moana, Oahu). 85 degree descending pass to the west. Total pass time was 9 minutes, 16 seconds starting at 13:04:57.

Click here to play the video file.

Total access time was 2 minutes 21 seconds from 03:09:11z to 03:11:32z. All stations were within a circle of diameter of about 120 miles. The north most station, AH6NF was the first on. The east most station, KH6DT was the second and the last on. NH6RZ was running 4 watts. AH6RH was running 10 watts at BL11bg.

Brief exchanges of callsigns and sig reports (59s) were done. The contacts tended to be unstable, with the sigs good for perhaps 2-3 seconds at certain moments, and other moments it would cut-off in the middle of the exchange. Not very good link quality for extended ragchew QSOs as experienced with the earlier 03:24z pass.

Attempts were made to compensate for doppler. In this event, access occurred on 437.800, and shifting freq to 437.805 extended the usability of the end of the pass about 10-15 seconds.

I was surprised that attempts to shift down 10 and 5 khz for doppler in the first half of the pass didn't seem to have material effect. Your access time and link quality into the repeater may vary.

Remaining crossband repeater passes for Saturday are at 4:13:58 pm HST 10 degree pass and 5:48:07 pm HST 22 degreee pass. Sunday passes are 1:53:15 am HST 10 degrees and 3:28:20 am HST 15 degrees.

ISS Cross-band Repeater QSOs, Fri June 23, 2006

June 23, 2006

Kyle WH6BIE, Dean KH6DT and Ron AH6RH held a three-way QSO via the ISS UHF/VHF Cross-band repeater. The QSO occured at 5:26 pm HST, Fri June 23, 2006 on a 55 degree ascending pass to the east. The usable passtime was 1 minute, 40 seconds.

Kyle used a Yaesu FT-50rd for the uplink and FT-2800M 5/8 monoband mobile vertical on a bicycle for the downlink. Dean used an Icom IC-2720. Ron used a Kenwood TM-D700 at 10 watts and 1/4 wave verticals mounted on the car.

Click here to play the video file.

At 7:04 pm HST, Fri June 23, 2006 a 5 degree ascending pass to the wast was measured. The usable passtime was 15 seconds.

Station used was a Kenwood TM-D700 running 10 watts into a trunk-lid 1/4 wave UHF antenna. No attempt was made for doppler frequency correction on these measurements.

Museum Ships Weekend

June 03, 2006

Operated Radio Central onboard the USS Missouri, BB-63, as part of Museum Ships Weekend. 20 meters and 17 meters began to warm up about 2:00 pm local time, was still going strong with some mean QSB when I had to leave at 5:00 pm local. We were averaging about one QSO per minute on each band.

Station 1 was a Kenwood TS-450S with an amp running 600 watts into a vertical on 20m. Station 2 was a Kenwood TS-450S with an amp running 400 watts into a vertical on 17m. See photos at http://www.kh6bb.org

Was great to hook up to Al, KH6ILR/3 in Washington, D.C. on 17 meters. Many thanks to Ned, KH7JJ, for an absolutely wonderful day!

First IP connection using Icom ID-1s

May 29, 2006

First digital data exchange over 1.2 Ghz using Icom ID-1 radios was done on Sunday, May 28, 2006 at 8:51 pm. Web access and e-mail operations were transparent. This paves the way to further assessment for using the ID-1 as a rapid means of deploying Internet connectivity to disaster scenes. See ID-1 IP programming notes on how to program the radio for simplex IP operations.

Two-way radio contact made with the ISS Space Station!

March 5, 2006

Seventeen hams across Hawaii made two-way radio contact with the International Space Station on March 5, 2006.

Watch the video: Two-way contact with Bill McArthur, KC5ACR

Six stations checked into the 147.06 Mhz net just prior to the pass. An additional five stations were at Waikiki.

Seventeen stations made contact with Bill McArthur, KC5ACR, in eight minutes, 51 seconds on the 19 degree pass.

With Bill's schedule, he may be on Friday night 8:00 pm to Saturday noon HST, and also Saturday night 8:00 pm to Sunday noon HST. Sunday UTC (Saturday night to Sunday noon) is his day off, so there is a better chance of contact.

Bill returns to earth at the end of March. Now is a good time to prepare for any future operation. Let's see if we can triple the number of contacts per pass by practicing NOW.

  • Program your radio's offset for -1.31 Mhz (Don't forget the negative offset).
  • Tune to receive on 145.80
  • Test that the transmit freq is 144.49
  • Do not transmit on 145.80. Bill is not listening on 145.80.
  • Listen for Bill to complete his acknowledgement of the previous station.
  • Call Bill with your callsign phonetically, and say "59".

Scenario for 2005 SET, Saturday Oct 1 9:00 - 11:00 am

Oct 2005

The scenario for Saturday's Simulated Emergency Net (SET) has changed. Originally, the scenario called for a recovery from a simulated hurricane. With the rainstorms that are the remnants of Tropical Disturbance Kenneth now in the vicinity of the main Hawaiian Islands, there is a possibility for confusion of the simulated emergency messages with actual, live messages related to the rainstorm. Confusion may also occur with the general public that may not be listening carefully to the radio traffic.

For SET 2005, the NCS will open SET as usual, taking check-ins, and announce the change in scenario from post-hurricane recovery. The new scenario is monitoring the actual rainstorm activity and passing reports of weather and ground conditions in ARRL Radiogram form to the NCS.

For SET 2005, compose ARRL Radiograms, addressed to the NCS (ie, State RACES NCS, OCDA RACES NCS, Healthcomm NCS, etc) and report weather and ground conditons. Please add your name and callsign for the signature block. Messages during this period counts as net traffic for SET. As time permits, NCS or other stations may send test messages to you.

Operations is expected to start at 9:00 am on these frequencies. There may be other frequencies that will be hosting SET 2005 nets.

  • SCD: 147.02/147.04/147.06 Mhz FM; 7.088 Mhz LSB
  • OCDA: 146.88 Mhz FM
  • Healthcomm: 147.22 Mhz FM

Depending on conditions, Skywarn may operate on 147.02/147.04/147.06 at the :00 and :30 of the hour, and on 146.88 at :15 and :45 on the hour with bulletins and message handling.

Since the situation is fluid, please expect changes with operations for SET 2005.

Stations are encouraged to create and pass test messages in the ARRL Radiogram message format. Test messages should start and end with the words "This is a test message" and the signature section should contain the name and title of the originator of the message.

Scenario for 2004 SET, Saturday Oct 2 9:00 - 11:00 am

Oct 2004

A hurricane named Yoza has hit the major islands of the Hawaiian Island chain, leaving all islands in need of relief and recovery. The simulated hurricane has left the area and is no longer a threat to the Hawaiian Islands. Each area may also implement their own scenarios in addition to the state-wide scenario.



Stations are encouraged to create and pass messages in the ARRL Radiogram message format. Messages should start and end with the words "This is a test message" and the signature section should contain the name and title of the originator of the message.

Official Anderson 30 Amp Powerpole Crimp Tool

May 2004

If you've ever tried making the 30 Amp Anderson Powerpole connector and had the wire pull out from the pin, you know it's a real bummer. Soldering the pin may lead to "wicking" of the solder on the silver-plated contact. The Gardner Bender GS-88 crimp tool requires delicate manipulation. Gardner Bender GS-88/Anderson Powerpole Crimp Instructions

If you are making several power connectors, consider the investment in the West Mountain Radio Powerpole crimp tool. Once you see the quality of the crimp and finished product (an absolutely awesome professional crimp...better than solder), its very hard to use anything else! It does a real professional job for about $50, 1/2 the cost of the industrial-strength hand tool.

If you want the right high-end tool for the right job, use the Sargent 4182 CT crimp tool.   At about $100, it is pricey.

Available at

Having made the recommendation through the ARRL ARECC CCE course of adopting the Anderson Powerpole as a universal power connection for emergency communications, I'm glad to see so many amateurs finding the merits of the connector, and to see the wealth of products available to meet the needs of the emergency communicator.

Inter-island 1.2 GHz Contact

July 1, 2001

1.2 GHz pioneers Dean Tanimoto, AH6IF and Ron Hashiro, AH6RH completed a Hawaii terrestial record for 1.2 GHz QSO. The QSO was from Wailuku, Maui to Makakilo, Oahu on July 1, 2001. The signals travelled over 120 miles.

The QSO was made by bouncing the signals from Maui off of the volcanic mountain Mt. Haleakala to Oahu. The ferrous and basaltic content of the cinders made it an ideal natual passive reflector.

1.2 GHz is alive on Oahu

June 17, 2001

Oahu 1.2 GHz pioneers Rick Ching, KH7O and Ron Hashiro, AH6RH completed an Oahu terrestial record for 1.2 GHz QSO on June 17, 2001. The great circle distance was 28.58 km (17.79 mi) between Palolo and Kapolei with one watt at each end.

The QSO was made by bouncing the signals from Palolo off of the volcanic mountain Diamond Head to Kapolei. The ferrous and basaltic content of the crater wall made it an ideal natual passive reflector.

More testing efforts continue.
