Thanks Bob,

You just connected to the VWS "powers that be" or at least to me, the 
VWS balloon program coordinator.

Several of us that attended the MD-DC briefing you gave were thinking to 
use APRS messaging to coordinate our launch and recovery teams instead 
of trying HF. We tested this the last launch in that we could see each 
others beacons via digipeaters. I would be happy to put out bulletins on 
our launch and recovery. Our team itself could use the bulletins rather 
than my directing messages to each team.

Do we have to be careful on the selection of bulletin numbers to not 
wipe out some other person's beacon?  Or are they indexed to the sender. 
Guess I will go look it up!
