I recently dug out my old 271A and have had problems with programming... have tried two different cords, and two different software programs and part of the channels just "aren't there" after uploading to the radio. After erasing and resetting the radio half dozen times I finally just kept sending the file to the radio and got them all to load. General consensus is the epromm is probably going out. never used to have any problems with it, and my newer 281A programs just fine with the same cords and software.Hey guys, just got an old radio up & running and am trying to manually tune but have a problem. So far, after a full reset, I'm not able to program anything into channel 1 or 4, the rest seem to go in just fine. Any ideas??
