The 240.350 is a AR Refueling Primary heard every day at my QTH (TN) loud and clear as their right over head in TN, KY, A, and NC. Every day their on. Good strong signazl here. I'm also picking up a lot of JSTARS but when they say "GO GREEN", theiy encrypt. 362.400 is one of their primaries and an important freq to monitor 24/7. Also, 121.5, the guard. You'll hear a lot of frequencies given out as well as open mics and more. I have a R-5000 VHF converter stucvk on it as there's activity all day long. I have 5 radios watching 225-400 Mhz but don't bother on the weekends or holiday's. It'dead..By the way the encryption simply sounds like noise/RFI, or interference. I have seen the carriers on the spectrum analyzer, modulated. Their real. Levels vary between 1-10 Uv.
