NBEMS (Narrow Band Emergency Message System) is a suite of applications designed for Emergency Communications.
FLDigi (Fast Light Digital Modem Application) is the main application providing various SoundCard modes from PSK31 to MT63-2000.
FLMsg provides form templates that would most likely be needed during an event. It includes the ARRL Radiogram and the ICS-213 forms along with many others. Both of these applications should be installed for use by GA ARES communications.
A really great site with instructions on how to download, install, configure and operate FLDigi and FLMsg can be found at The Western Pennsylvania ARES group.
