This led to another interesting activity.   How to find, on the
APRS-IS - or better, on the air - what is the callsigns of the
stations running YAAC (or any other APRS client)?

I tried a ?APRSP to ka2ddo but no response...


Another interesting twist - how would a user query their local client?
  Sending a message to self?  Enter the query at the command line?
Probably varies on all the clients.


I found a nice list of queries at:


It's missing SMSGTE and WHERE but otherwise has enough to keep me busy
for a long time.
