Here are some information on the VHF and UHF repeater systems in Hawaii. If you are visiting, I recommend you bring along a magnetic mount mobile antenna to extend the range of your handie-talkie radio. I have a Comet B-10NMO which I use when I travel. The Diamond NR72BNMO is similar. The uneven terrain, valleys and mountain ridges affect your ability to get out from the mobile and access the repeaters.

Enjoy, and feel free to drop me an e-mail if you have any questions.


  • Hawaii State RACES Inter-island VHF repeater system
  • If you are visiting and staying in Waikiki, tune to 146.880- The daily net is at 7:30 pm local time.
  • EARC Repeaters on Diamond Head
  • A note to visitors staying at hotels in Waikiki. The popular repeaters located on Diamond Head are located on the northeast side of the crater rim at elevation 440 feet. Waikiki is on the southwest side of Diamond Head at sea level, so you're in probably the worst location trying to access those repeaters. Building heights are restricted to 350 feet, so you won't have line of sight with the repeaters from the Waikiki hotels. You'll need a good antenna, a good location (such as a large window or lanai (balcony) at least one watt (preferrably five watts or more) of power, and good elevation to get above the nearby hotels. An external antenna, such as a magnetic mount antenna and aluminum foil for ground plane or flexible j-pole antenna from 300 ohm TV twinlead is strongly recommended, unless you know exactly which hotel room you will be getting.

Note: I often get inquires about good repeaters in the Lahaina/Kaanapali area. If you're vacationing there, note that it is a repeater black-hole on VHF and UHF. There are no reliable open repeaters accessible with a five watt handie talkie from that area.
