Spe amp wont ccommunicate with the flex software for band change etc
Flex 6300 amp 2k-fa. Connected serial cable supplied by spe made for my radio to the radio 1 cat db15 and the other to an available db9 serial port on my pc. Amp ignores the computer. Cat on the amp is set to Flex 9600 baud but no joy. Cannot seem to change bands manually on the amp either.
