OK, blog readers, here's another federal frequency mystery for you...
163.4625 MHz, NAC 001, radio ID of 1, talk group of 1.
Heard encrypted communications in the Seattle area recently. A check of my logs have shown that it mostly appears to have been allocated at various military bases across the country.
I have logged it with various NAC values at some of the Super Bowl games I've been working.
The NTIA allocations seem to indicate military or Department of Energy allocations.
Any guesses?
