[App_rpt-users] Using a Master II

[Jim Duuuude]

A man who has been working with app_rpt and the USB fobs for a number of years, and his
sister, who has just recently gotten interested in doing the same are having a discussion:

The sister asks: "Why do you have to set the squelch at least 100 points higher then the no-signal RSSI value now,
but you didnt used to have to several years ago?'.

He replies, "Well, thats just because of history, sis."

    I think the audio out lines on the back plane are de-emphasized or
    flat to 3k then it rolls off. Either way In this case that is not
    what you want. If you were connecting to a hardware controller and
    using the cas/RX mute then it works just fine. 

    In the case of using DSP squelch and DSP L decode by the fob/ URI it
    must be connected to the Discriminator.  You could also set your
    node to speaker out instead of flat and use the USB for the cas
    connection.  That should work too. 

    

    I personally like using the DSP Squelch and DSP tone as it is very
    quick - no squelch busts! That is... if you have the RX squelch set
    right.  ;-)

        This
            is making some sense
            now.  I did pull off the back plane but I never traced it
            back to see
            where exactly it was coming from.  Many moons ago I followed
            the Scom 7k
            to Master II hookup info.  I have always just used that same
            spot on all
            other controllers in the past without an issue and excellent
            audio.  I will
            give that a try tonight.  I know what pin you are referring
            to.  It
            would be the same pin that you would use in a mobile
            conversion and it is also
            available where the stock PL board would plug in.  
         
        Thanks
            and I will give it a try
            this evening!

        I have set up a Master II repeater station
          in full duplex
          mode using a URI for dsp squelch and dsp pl decode and it
          works just fine. The
          main thing is to connect it to the volume/squelch hi (raw
          discriminator) or you
          will have problems. The master II should be able to give you
          1V p-p output with
          1k tone @ 3k dev on the volumw/squelch hi which is not
          available on the back
          plane. You have to pull it off one of the connectors on the
          drawer. Have to
          check my notes on what pin. 

          

          Any way I have a couple of units working in this manner with
          no problems.

        So I have been using a GE Master II
          repeater (actual
          repeater, not a converted mobile) for the allstar node in full
          duplex repeater
          mode.  I noticed it just doesn’t dig too well when using the
          fob to
          decode the PL.  I have a maxtrac on another fob and that will
          dig into the
          noise great.  As a test I hooked up a ts32 and ran the output
          of that in
          the CAS/COR on the fob and it worked great!  I want to try to
          get the
          built in decoder working correctly though.  Another friend of
          mine is also
          running a GE Master II and he is having the same problem. 
          When we run the
          rxnoise level from either the radio-tune-menu or using the
          radio tune command
          from asterisk it always fails.  Anyone have any suggestions on
          a way to
          resolve this?   I have another use for my hardware pl decoder
          so I
          would like to get the USB Frob working correctly!!!!
