These were all great radios of the day. The ICOM 2AT may have been the most popular of them all, easy to use solid radios that are still in use today.

In 1976 repeaters were built from a kit or retuned commercial repeaters. The ICOM IC-215 and Kenwood TR-2200A were the radio of choice before Hand Held radios were on the market.
