Hello. I have a Link Communications RLC-1 controller that has a bad repeater port. The only thing wrong with that port is that the 2n7000 FET that keys the PTT is not getting a signal from the processor. I checked at pin 36 of the CPU and it only has .37 volts when it tries to key up the transmitter. I have the link port setup for repeater, and I get 5 volts and pin 35 of the CPU. That port works fine. I have narrowed this down to something wrong in the processor. The processor is an MC68HC711E9. I can get these through Mouser and Allied. Does anyone know if these will work or are they programmed from Link Communications for their controllers?
