Probably, but it would be an involved mod with some serious thinking required to get it done. I did it once using an external TP-3200 Tone Panel and it wasn't very easy. > I don't have the TRN5073A schematic, only for the TRN5075A. > Q201, Q202 and some resistors/diode are missing on my board. > Guess I need them to control the PL ?? There are options to disable the CTCSS during paging and other types of non sub-tone operation so a little homework with the Station Control Manual would turn up the reasons for the unpopulated part locations on the Module PCB. > Sincerely, > Eric VE2TSO cheers, Rubber Chicken
