From personal experience,the SAV-17 output brick is unforgiving of any
high duty cycle use and will die. They are not cheap to replace either.
And I only use my TMV7A for mobile use. This radio is a poor choice for
remote base transmitting. I would dig into the radio before the output
stage
We took discriminator audio from inside of the radio.

Hmmm, yet another thing to complain about to the vendors at Dayton, along
with the lack of split-tone capability.

Uh oh, my G707's starting to lose some display segments. I know

Well Mathew, being a general, and with all the nice gear on the wall
in your shack photo on QRZ, you should learn about Optos. If you can
wire up a LED with out letting the smoke out, AND use a NPN
transister for a DC switch then you might be able to use an OPTO to
control an 8Volt device from
I am asuming no one came up with a schematic.
All parts can be obtained from www.web-tronics.com
You can replace D1 with what ever voltage you need up to 11V to allow
head room for the NPN transistor to function, And you can replace D1
with a 10K resistor or if you just need +11 or +12 COS
I forgot, you may have to add a 100K resistor accross D1 depending on
the controllers loading.

I agree, you way sounds better,
But I am taking discriminated audio, and building my own cor circuits

That was a good point out, never gave that a thought, so now I will just build 4 cor circuits to make them work, that will be easier than trying to make 5 volts jump to 8, can just make a simple 10 or 8 volt COR circuit. Glad this came back up a 2nd time around.

You can pull a "cos" out of them that follows PL by
tapping the rx mute transistors for each

An opto certainly would get you there, then.
Digikey has some nice ones from Panasonic and NEC with CTR's above
10-0%, so you could doinverting or non-inverting conversion with only
the opto and a pair of resistors.

Thanks Ken and all, appreciate it very much for the input. I basically need to just present a cor circuit to key the RVS-8, just using the already available voltage from the TM-V7 and push it up to key the circuit. I don't know why they made it to require so much, but it's their design, I just
