I need to add CTCSS to transmit of ICOM IC-260A. I have a manual (file)
but no schematic. The manual says that the accessory connector pin 5 is
"output of transmit mic amplifier" or words to that effect. Can I put
CTCSS tone signal into that pin on transmit? Other suggestion? Anyone
care to look at their schematic of this rig to tell me where this pin
of the accessory connector goes?

Very tks,
