The new units I have been looking at have an optional module that is installed in the transceiver and allow direct connection to a PC serial port. I assume the optional modules are effectively TNCs. Are the TNC connectors on the back of the unit that don't have an internal TNC merely sound input/output circuits? If there is NO tnc behind the serial connector this is a serial portfor controlling qrg mode etc Bob Macklin K5MYJ Seattle, Wa.
