Yeah, I can tell the squelch is open from a few different points:

1. Monitoring with an external speaker, I can tell the radio is
receiving from the RF repeater
2. Using arecord, I can tell the audio is making it through the
soundcard to the OS level (and sounds decent, too).
3. Monitoring the svxlink log, I see squelch open/close or distorsion
messages, which tells me svxlink is receiving [what I assume to be] audio.

Right, which is pretty much what I've done so far while trying to narrow
the issue down.  What I'm really hoping for is some way to validate
specific things are firing or failing in the software itself.

Actually, what may be a related question.. Should the audio from the
short and long id be audible on an echolink client?  I can hear it on
the actual RF repeater, but I don't think I hear it on my iPhone
echolink client.  If it _should_ be audible on an echolink client, then
that's even more confusing since I hear the "connected to svxlink, blah
blah" message when I first connect.  I would expect to either get all
audio or no audio, not only select audio.
