Currently only the APRS Messenger program does APRS-over-PSK63. Any
TNC-based approach would only do conventional AX.25 300-baud
conventional HF packet mode.
[The APRS Messenger app (which at first glance looks like a typical
waterfall PSK app) actually prepends and appends normal typed strings of
text with quasi-packet headers and checksums. And implements the
ack-inside-an-unconnected frame that normal AX.25 -based APRS uses.
As a result, normal PSK apps like DigiPan or MixW won't interact
correctly on 10.149.700 correctly. ]
