RE: [Repeater-Builder] Mastr II Audio

The J3 and J4 are for a high pass audio filter board to plug into (i.e. used in CTCSS stations to strip tone from RX audio) , as I recall J1 and J2 are 10 volt and ground.  However, I don't have my manual here at the moment to verify.
The GE Mastr II service manual clearly details these (and all other) options and circuits on the board.  It sounds as if you don't have a manual, if your planning on doing any interconnection into the Rmt audio board or anything else in a Mastr II I'd strongly suggest you get some documentation in front of you, it is essential to have both a schematic and board layout drawing when your working, otherwise your in the dark or just guessing half of the time!
The Rmt. audio board can support a good number of controller interface functions, as RUS, RX audio, TX audio, regulated 10 volt are all present on this board.   There are also a number of jumper options available for various functions.

Subject: [Repeater-Builder] Mastr II Audio

    Here is a real test for the GE guru's - I have the repeater audio card from my Mastr II
in my hand ( actually an extra one ) GE #  PL19D41721�G1 Rev. B
    I can see on it there are J1 - J2 - J3 - J4.  Is there any body that can tell me what each of these pins are?  J3 and J4 are both 3 pin plugs - 1 and 2 are single pin - I was wondering if I could put
a spare controllers audio directly into this board at possibly one of these pin connections. I would
like to wire this controller so that it could be used with the GE control boards and plugged in
when I wanted to unhook my main controller for service or whatever. Any takers on this one?
