Icom R-72
Manufactured by Icom, Osaka.
In 1986 Icom released the successor to the IC-R70, The R71 is technologically similar to the IC-R70 but has 32 digital frequency memories.
Caution: the microprocessor code in the RAM of the radios processor is maintained by a backup battery, if this is exhausted or the battery is removed for replacement, the RAM content is lost. In the past the set had to be sent to Icom for reprogramming, today this can lead to total failure.
