Is this possible?

I think their radios will go about anywhere they want them to if I remember correctly, so I guess my answer would be yes, it is possible....... I believe there are some Civil Air Patrol channels that are close to the CB band.......

 

look up in the sky to confirm!

 

Likely legit. I wouldn't be at all surprised to find that a CAP plane has an HF rig in its stack.

 

not suprising my dad head 1 come over the radio in his tractor in 98 i believe

 

Many have an HF radio among others.. It is probably against some regulation to chat on CB.. However, testing the HF radio is testing the HF radio. What better way to informally check it, the antenna tuner, etc. at the higher end of the band..

 

As long as they never said "What's the 20 on the babydoll???", they were probably the real deal.

 

Sounds like it was probably legit to me, and either lawful or close enough to it to pass the "Aw, shucks" test for it.

Even though the newer, simplified CB Rule 3(a) would ordinarily prohibit a Federal Government agency from using CB, and *anyone* from using a transmitter that was never certified or certificated (for the newer stuff), it's easy to imagine a lawful scenario that would produce this "rolling QSO". I can imagine civilian observer, mayhap a meteorologist or just an uncle or friend of the Pilot-in-Command who gave (or got) permission for said civilian to be aboard and tie his personal CB handy-turkey into a coax that a flight engineer made available to him for 11 meters.
There *are* CAP HF frequencies scattered around parts of the bands; Griefkit used to make a couple of crystal-controlled SSB transceivers in the HW/SB family line, that I think were capable of only two xtal-controlled freqs. But they'd have to have been kludged like all get-out to show up on CB, and AM at that. But having the mode, TX, and RX freqs all off at the same time? Naahhhh. Sounds like *something* in the aircraft was dialed up properly on frequency with the right mode selected.

I think it's more likely that the PIC or some other bored crewmember dialed up his unimaginably expensive Wulfsberg, Rockwell Collins, or other "dial-up-anything" transceiver to, uh, assess the operational bandwidth of the radio set and confirm functionality on its lesser-used modes, like un-encrypted AM over low power line-of-sight paths. Yeah, that sounds more likely. The rules *do* permit CB operation from an aircraft in flight within US airspace with permission of the PIC, and who's really going to complain, anyway?

Years ago in Alaska, I got to talk to a 2 meter ham repeater (just above the aviation VHF freqs) a little over 200 miles away with a 3 watt handheld. The "trick" was that I was in a Cessna 207 at 8,000 feet, hooked to an external antenna on the belly of the fuselage, and I was wearing SetComm noise cancelling headphones & boom mic, or there'd have been nothing but noise at either end. I was northwest of Mt. McKinley, and the repeater was on one of the Loran-C towers at Tok.

Low power can do amazing things once you have a line of sight path. As soon as you lose it, that's when you need "bigger ERP" for local comms.

So if we're taking a poll, I'm going for it being a no-fooling-story. Or at least a good fake by *some* aircraft with a CB in it.

 

I say he was pulling your leg...Guys around here will get on 19 and talk like they are Air Traffic Controllers talking to planes landing at DFW airport all the time...

I would say chances of that guy flying over is highly unlikely...
