Hello I have 4 of the SMU300K UHF Radios. I thought they were the SMU300 but their is a k at the end of it. I think these are the older eprom units. Does anyboy have any infomation regarding these?
The programmer that I have is the AMX 500 which works great on the newer radios. Since I thought these were the smu300 I read the radio then when I went to program it flashes 0 now. If this is the eprom can it be reprogrammed? Is there an adaptor or software to program these. I also have access to an AMx500C Stand alone programer and an AMX 190 cable. The Software version guide shows a amx191. Would it still work?
