A interesting development. When I key the radio, my TS=570D, I get the
mark tone, in this case 1275.
Decided to test if the FSK keying circuit is actually working. Stuck a
cutoff wire from a resistor into the ACC socket at Pin 2 which is the
FSK keying pin. Set the radio to transmit...heard the mark tone.
Shorted pin 2 to ground and the tone did not change.
I just love old radios
Did the same thing to my TS-480 and the tone changed just like it should.
Have cable for TS-480 on order for my TI-8
Thanks for putting up with me...it has been a trying week past.
