After using the Icom IC-2820H I was thoroughly impress with the sound quality. I will post a full review here in time...

Basic Usage

cross band repeat

No modification to the radio is necessary to use the cross-band repeater capability. This is a native function of this transceiver even though it is not covered in the user manual.

  1. Select remote or repeater VHF frequency on the left side (in VFO or a memory channel)
  2. Select your local UHF frequency on the right side (In VFO or memory channel)
  3. Push the "F" button and hold in while next pressing both RIGHT and LEFT Band Knobs until you hear a BEEP
  4. The key icon will flash on the right of the LCD display if you successfully activated cross band repeat mode

TO DEACTIVATE: Press "F" until you hear beep and/or key icon (in upper right corner of display) disappear.

These steps will allow you to use your radio as a crossband repeater. It does not have an automatic ID announce. You must therefore announce you are operating on the frequencies with your FCC call sign.



Mods are available for the IC-2820H. Recommend mods: physically alter the microphone to increase low frequency voice response. Optional mods: expanded coverage modification. Other mods available.

Verified working mods will be discussed here.
