[aprssig] APRS Messenger now has APRS over PSK-63

[Lynn W. Deffenbaugh (Mr)]

Pop the $$$ and get the AGEPE PRO version.  It will do KAM tones 
natively and the dial frequencies line up.  That's what I'm running as 
KJ4ERJ-1 (my APRSIS32 client talking AGW to AGWPEpro and TEXT to APRS 
Messenger).  APRS Messenger is running as KJ4ERJ-15, but is receive-only 
until I can get a 30m antenna put up.
