Odd frequency hit today...

[ur20v]

Earlier today I was playing around with SDR# and DSD+ and I stumbled across an oddball I can't seem to figure out. A relatively strong transmission on 149.0675mhz caught my eye, and according to DSD, it was encrypted with AES. Curiosity got the better of me and I started researching, but I really can't find anything and I'm left scratching my head. Any ideas?

In case the question arises, I was using my main scanner antenna, a small outdoor discone mounted about 20-25 feet above ground level.

From the NTIA Redbook:

In the bands 138-144 MHz, 148-149.9 MHz, and 150.05-150.8 MHz, the fixed and mobile services are limited primarily to operations by the military services.

Interesting, thank you for the info.

149.0675 is likely not the correct freq

That band is Gov/Mil and likely the Freq is [depending on your calibration]

149.0500
149.0625
149.0750

See if you can hear it on a Scanner or other radio
