So, I occasionally look at aviation radars because why not. I noticed last night that there is this weird plane circling the metro for hours at a time and I can’t seem to find out why. Any of you guys know what channel the USAF would be using to communicate with the ground if it’s not digitalized? I would think they’d be tied in with normal ATC but at the same time seems like a security thing. And between the two Tower channels Radioreference provides, does anyone know which is the prime one? Thanks! The plane doesn’t have any info to it besides the name ALLIED1 and the speed and elevation. Can’t figure it out.
