if you are talking aprs style contact it is usualy done like this: station A sends a beacon station B sends a bullitain message with all the calls he has recieved so far in the pass Station A sends a bullitain message with all the calls he has recieved so far in the pass if station A is in the list of station B and Station B is in the list of station A I would say it is a confirmed contact.
in most places there are igates that will send the pass to the APRS internet stream and you can check back on aprs.fi or findu.com
