This program is usable in poor conditions and provides 100% accuracy in its delivery of messaging using an error free protocol (ARQ).
There is a full presentation involved in the use of VarAC. It is a powerful tool that can send mail, provide instant messaging via one-to-one keyboard chat to the exclusion of others or can send specific short messages to all where required.
It can also be encrypted with permission from the user services. Depending on size, files and pictures can also be transferred using this program.
This software is still being tested by some local RAYNET teams but is appearing robust and accurate for Emergency Comms use.
