[FedCom] Civil Air Patrol Transition to New Frequencies

[Michael W. Scheel]

Actually there is a small program that will decode NAC out of the P25 
stream. It's included with the Unitrunker program, But you run it as 
separate program with the discriminator tap inputted into a sound card 
for decode. But as you say no scanners support the NAC yet. (maybe a 
upgrade to the BC396/BC996?) Name of the program in the Unitrunker 
files? "NAC" of course.

It finally got down to the question of which should
be permitted to remain in the field--the war correspondents or the
soldiers. There wasn't room for them both. It was decided to retain
the soldiers.
