The flight ID indicates that's the Army Golden Knights. It's the former N171AV msn 315 not programmed with a military hex code yet.
i don't know where my brain is, the GKA is why i clicked on it and soon as i saw sierra nevada i completely forgot about the GKA part. Rather large plane for the Knights to be using, i wonder if its actually theirs now or just renting it from sierra nevada.
and nice job on pulling out the HULKY callsign, i am terrible at interpreting stuff and had decided it was HOKIE before i saw your post. Messed up callsigns take up waayyy too much of my time. a while back a c-130 from the PR ANG came by KVUJ, got pics of the tail number and very very clear recordings of pilot and tower saying the callsign. no question, without a doubt, it was RAYGUN78. could find zilch that connected the callsign to the unit. then when that c-130 from the PRANG recently crashed in georgia, i came across a reference to the callsign it was using....RICANxx.
KJ4LZM: if i have my days straight i was picking up similar traffic about 8pm that same day, CAS by F-15E's on 264.6 and 252.525 so that might be worth punching in too. will be punching in 263.15 myself now as i don't believe i have come across that one before.
freqhopping nailed the interpretation and saved you the months i had to spend figuring all that stuff out on my own. fair bit of CAS training done over in my area west of the uwharries, regular military and contractor air units, if you punch in 227.475 you'll catch some more similar type traffic, though there is no telling who or what is or isn't real that you'll hear on it. when i first caught it it was being used by real deal AH64Ds and since then has run the gamut from cessna 337s IDing as MQ-9s to real C-130s, up to and including the previous 2 days, and likely this afternoon as well, by a crop duster

IOMAX Archangel. if theyre up high enough you today you might catch it cause when they have been or in the bragg area i have gotten weak rx's when they are 5k and up.
also if you haven't already def put in 389.65. tonight is the last night for the excercise i believe and the traffic i have caught on it, i would like to have someone else vouch for it. i dunno what to make of it and it connects to another weird thing i have been trying to figure out. punch it in twice, AM and FM so you can toggle it if you are around the scanner cause its brief and weird.
