In yrs past (I mean like back when the F-4E was our most advanced fighter) I used to mess a bit with CB radios......I was one of the ones who actually had an FCC lic to use them and before every chicken slinger and his sister/mama (yeah I said that) got on there to run their mouths. This was far before cell phones etc, and my pals and I had "portables" that we slung over our shoulders with battery packs, about the size of a .50 cal ammo can. One guy even developed a "phone patch" where we could call him on the radio and he could patch us into his telephone; very advanced for high school kids, hell, for anyone back then. Used to scare crap outta the yocals.
We used proper radio procedure and I was familiar with aviation usage as well from flying with my Dad. If I still had that stuff, I could make some pretty convincing exchanges with somebody on another radio (if I had a 30 hr day). Certainly better than the recordings that were apparently made at a cross dressing convention in Russia.

I even learned how to jam the jabber mouths who blocked the air all the time with their overpowered nonsense - I'd take the squelch off my scanner and key the mike over it. Totally jammed thier lousy keysters, sorta like EB-66s over Nam; they were my inspiration after seeing an interview on the news one night where an officer said he did similar sometimes.
So yeah, the radio stuff could be done with moderate equipment and proper technique. I'd add some profanity in assorted languages to, as I've heard alot of recordings of pilots in combat in Nam and since; they aren't very politically correct. May fav transmission was in a dogfight w/Migs over N.vietnam;"What the F, over?" Proper radio procedure.
