From my VERY limited experience with other people's GE "stuff", the transmitter, being phase modulated, has 2 inputs. One for "program audio" (amplified audio from
I dont have any GE equipment. I just asked the "Guru" on your behalf. the MIC) and one from the CTCSS ("Channel Guard" as it's known in the GE world, I believe) encoder. This requires you a use, say, the 'A' output for program audio and the 'B' output for CTCSS. In fact it was GE transmitting equipment that "inspired" us (me/Steve Henke) to implement the 2 independent outputs the way in which we did. Of course, the 'other' output (usually 'B') can also be used to drive a 'local speaker' or something of the sort, in a case where the 'main' (usually 'A') output is generating directly-modulate-able audio (pre-emphasized audio along with CTCSS). That's about all I know. Sorry.

Or A going to one input and B going to a different input. How would you say your audio quality is. I get this strange intermittent. Clicking or popping sound. Almost like a heaphone or microphone being plugged into a board. It's soft but noticeable. Usually at the beginning of keyup or at the end of transmission. I noticed this one one repeater I setup. I then setup a second repeater also a mastr ii at a differnt location also using usbradio and I hear the exact same sound. I was wondering if you would be willing to share how you interfaced your equipment and possibly a copy of your usbradio.conf file. I'd like to rule out what is going on. Also maybe do you notice how clean your repeater audio is. Not many people compain about or even notice it but I do.

Remember, for transmit, you need to feed it SEPARATE "program audio" and CTCSS (you will need to use BOTH outputs of the USB device separately).

I'd like to talk to you directly to ask a few questions on your setup. I have a strange problem and would like to make sure I'm setup right.
