An update to this. If I put the jumper on JP1 it puts the radio into transmit mode until I turn it off. If I listen with another radio I can hear the audio. I am running it into a dummy load right now but enough still gets through to hear it.
Anyway it seems like for some reason the Recv COS signal isn't reliable. Every once and a while it will key up right but most of the time it doesn't. I guess the next step is to find out which line they are pulling the COS from and see if that may be an issue. Any other suggestions? --- In [email protected], "mung_bungholio" <[EMAIL PROTECTED]> wrote: > > I purchased a GE MASTR II with an RC-1000V controller and I am having a > problem with it. > > When I power it on it transmits the ID and seems to be functioning like > it should.
