Hi Gang,

I am trying to work a circuit that I can use to
program a VHF receiver. I'm going to use the Maxim

snippety

Are you 100% certain that this particular radio even uses TTL levels on the
programming side?

I say this only because I work with TK-790's frequently, through my day job, and they
do not require any sort of RS232 to TTL conversion. They're programmed through a custom cable
straight from the computer's serial port to the microphone connector.

Perhaps you should dig into the 690's service manual before expending much effort?

Happy hunting.
