ID and Translation Requests / UNID 7535 USB MilAir? 20FEB20
« on: February 20, 2020, 1850 UTC »
I have been monitoring this frequency for a week now, with lots of traffic today. Sounds military but not sure. Stations are always contacting Sea Ceff or trying to, sometimes he doesn't respond. Some call signs heard include Saint George, Black Onyx, First Gator, LightningStrike. Sea Ceff seems to be a stationary or ground station.

They transmit in voice and also data which sounds like MIL-STD of some kind. They also refer to TX in red or green.

Today Saint George was testing transmitters with Sea Ceff for almost an hour in four different voice modes and using numerous excitors. I videoed this and condensed it down to 9 minutes. I'm copying this in Ohio. 1512 UTC 20FEB20.
