As Chris mentioned, I'm running APRS Messenger (2100hz) on 30m using the 
station described below.  The nice thing about the frequency choice 
described above is that you can tune the dial to 10.147.600 USB and use 
AGWPEpro with KAM tones to decode 30m APRS and run APRS Messenger 
(2100hz) in parallel looking for PSK63.  At least, I think that should 
work, I know that APRS Messenger isn't interfering with AGWPEpro, and 
the waterfall in APRS Messenger shows me the audio activity on the 
frequency.  However, I've not yet decoded any PSK-63.

There's listening ears here in Florida on 30m, so if you fire up APRS 
Messenger, hopefully I'll be able to provide a reception report!

My station is an iCom 706 connected to the internal sound card in my 
Dell Vostro 1700 laptop.  APRS Messenger and AGWPEpro is listening to 
the audio signals.  I have my own APRSIS32 client connected to AGWPEpro 
and IGating as KJ4ERJ-1.  I have APRS Messenger configured as KJ4ERJ-15 
and connected to APRS-IS as well.  All of this is RECEIVE-ONLY as it is 
connected to an 80m dipole without a tuner.  Obviously, it would not be 
wise to transmit just yet.  I'm hoping to have my son (KJ4DXK) put up a 
30m dipole tuned for 10.147.600 just for these programs.  Oh, and I 
haven't crafted a PTT cable yet, just a simple audio-isolation 
transformer on the receive audio to line in.

I'm nearly always online for APRS messaging as KJ4ERJ-12.  That's my 
APRSISCE client running on my Windows Mobile which is nearly always with 
me.  If you don't get a response shortly, you'll probably get one 
later!  If you're not online at the time, check the Messages link at 
APRS.FI to see what I may or may not have said in reply.
