[aprssig] Re: d700 miniDIN

I discovered something interesting on my TM-271 - seems that the 1200 baud
receive signal isn't fixed level.  I was running a tracker off of it and
found that it wouldn't show the channel as busy with the volume down.  It's
pretty easily fixed by using the squelch output instead, but I thought the
mini-DIN signals were supposed to be standardized.

Anyone seen this on other radios?

     De-emphasized squelched audio similar to what comes out the
speaker, but at a fixed level unaffected by the volume control. It is
sometimes labled "1200 Baud Receive" or "RXD".
