GROUP DESCRIPTION:
This group is intended for the sharing of information related to the iCom IC-91A and IC-91AD hand held radios and the exciting new D-Star technology in general.

RADIO VERSIONS:
IC-91A is the American version of the ID-91. It requires the optional UT-121 digital unit in order to operate digital voice mode.

IC-91AD is digital ready right out of the box.

ID-91 is the Japan version. (At the time this group was started, this was the only version. Thats why the group is named ID91 and not IC91. This is the original group)

RADIO DESCRIPTION:
The Icom IC-91A/AD transmits on 2 meters and 440MHz at 5watts on either band or 0.5 watts on low setting. It features extended receive from 495kHz to 999.990MHz and 1304 memories. The A band (top) has wide reception from 495kHz to 999.990MHz in FM/WFM/AM. The B band (bottom) receives from 118.000 to 174.000MHz and 350.000 to 470.000MHz in FM/FM-N/AM/DV modes. A combination of the A band and the B and can be received simultaneously, so V/V, V/U and U/U can be utilized.

The digital voice and data mode conforms to the D-STAR standard. In DV mode, you can record 30 seconds of audio into memory or 15 seconds into 2 memory slots, or 10 seconds into 3 memory slots. It will also play a recorded message up to 10 seconds in response to a call directed to the user's callsign. Audio messages can even be forwarded.

Dimensions:

Will D-Star technology revolutionize the VHF/UHF ham radio bands? Only time will tell. Fellow hams in the US are experimenting with this technology and experiencing what it has to offer. The benefits of narrow bandwidth are promising to help our crowded vhf/uhf bands. The features of digital communication are intriguing. Let’s explore what we can do! Post any information related to the ID91 and IC-91A /AD radios AND any information on D-Star technology.
