USAF MARS Frequencies are shifting - again!



From Tom Sevart (N2UHC) via Rachel Baughn, MT Editor:

"I thought you might be interested in this intercept of an AF MARS net in MFSK16 I copied tonight. Looks like AF MARS stations are going to change from using freqs ending in .1 and .6. From a new directive they're going to use logical freqs that end in .0 or .5."

From the MARS Broadcast:
