Steve,
Be aware that those transmitters are dirty.
There is a note about a module using the same RF circuit on Doug's
HAMVIOP site.
He suggests a filter. REQUIRED if you are going to drive a amp or
even connect it to a antenna!

Thanks. Formy first full duplex repeater (for test/learning purposes) I
am going with 2 of those modules and a 6 cavity duplexor
(likely of the ‘notch’ variety). If it works out may put my
Mirage BD-35 on the TX side before the duplexor and get ~16
watts for giggles.

Audio detection circuit to generate
‘COR’
Steve COR or actually RUS "Receiver UnSquelch" is available in that radio.
You have to unsolder the shield to get
to it.73, Steve
