- Hello all,
The NBEMS team has provided a very useful tool for MT63 (as well as any other mode) with a new feature called WRAP.
WRAP is a simple program that calculates a checksum feature for a single transmission. This feature allows an unlimited number of stations to confirm 100% accurate receipt of a message as apposed to having to make a one on one connection with an ARQ mode.
Check out NBEMS/FLDIGI and the WRAP feature. We're using the combination of MT63 and WRAP for emcomm here in Western PA and it's starting to catch on across the country.
One more excellent tool for emcomm!
BTW, here's a few video demo's:
