When I was in the Air Force as a comm tech, they used to run 13, 16, and 22 channels of teletype (60-100 Baud) multiplexed together and shot out over a voice channel over some comm link (long haul multi-hop HF, VHF, UHF, and MW.
As they were staggered in frequency up conversion and multiplexed together to be sent out over a 3kHz voice channel, the sound was exactly like a 4 engine propeller airplane - exactly. If you tuned in on HF bands, you’ve likely run across this if you’re old as I am.
I had the opportunity to fly in a B-17 several years ago.
Unbelievably LOUD!! No way to carry on a conversation without yelling.
Definitely worked aboard a P-3. Not so much a P-2, as there usually was something wrong with one of the engines.
We had an old stand up cabinet radio in the basement when we were kids. Tuning across SW we would hear those buzzing and roaring sounds and didn't know whar they were. My best friend [at 14 y o] solemnly announced that noise must be coming from the hydroelectric plant cause nothing else could be that powerful.....(:}
Reminds me as a kid hearing a squadron of B36’s fly over the house. It was like God’s own beehive.
If it was between 3 and 30MHz it was more than likely what I’m talking about.
My late uncle flew the B-17 during World War II.
As a college student in Los Angeles MANY years, ago, I lived in an apartment not far from LAX (Los Angeles International Airport).
In the middle of the night, they sometimes did repair and maintenance work on the jetliners, and they frequently had the engines running for a period of time. That sound of jet engines in the distance would always lull me to sleep.
In the early 60s my dad was stationed at RAF Bruntingthorpe - base housing was single wide trailers with a large room attached. The housing was located right beside the runway. There were a lot of nights when you could hear the aircraft making touch and goes. I loved the sound and slept better on those nights. To this day, I have to have a sound machine on for me to fall asleep.....
Nice recording for sleep - though the flack explosions at 3 am might take some getting used to.
I remember two distinct signals, one was rhythmic chatter and the other an annoying buzz-saw. I was told the later was Russki jamming.
We used to hear jamming (signals meant to keep frequencies clear from international use - Cuba did it a lot)....we called them bag pipes.
They did this to keep those frequencies clear because at some point during the day or night they planned on using them and wanted to keep them clear. For long haul HF, changing frequencies throughout the day was a rule. Higher freqs in the day and lower and lower ones at night. Those D,E, F1 and F2 (these two mostly) layers of the ionosphere are fickle.
You know it. There was an old C-47 still in service near our squadron at El Toro. When they would fire it up, all the car guys would wander over just to hear it idle.
hehehe
You are very naughty, FRiend! :-)
I liked it & thought it very well could be soothing & sleep inducing. There are so many possibilities with other planes(especially P-51s)& various other sounds not related to places. Very clever idea.
Thanks, Ma! Sorry, ColdOne....round motors rock! If I could mount a P&W Wasp on my truck....well....there’s a thought.
Had to look up Bruntingthorpe. I see that B47s and RB66s used it for a few years and moved out in 1962.
The Brits have an air museum there now. One of the planes is a Nimrod anti-submarine hunter. Saw one put on a display at an air show and was extremely impressed by the maneuverability. The pilot handled that big dude like it was a king sized fighter.
My dad was not a SAC guy but got detailed to a B36 squadron doing high altitude take-off tests and fuel consumption tests at Holloman AFB, NM in the early 1950s. Don’t know if he ever got any rides in an Aluminum Overcast or not.
lol.....
reminds me of that list of pilot/ATC interactions...where the frankfort ATC gets irritated with a british airways pilot about his manuvering around the tarmac...ATC guys yells at the pilot: “have you never been to frankfort before?” pilot: yeah, twice in 1944, but it was dark, and I didnt land....”
funny stuff
Let’s face it, that generation of Germans pissed me off a bit.
I will relate a story of a time I trained in Germany while in the IDF. For whatever reason, a crew of us (about 12-15) decided to go to the Hofbräuhaus München, in our Israeli flight suits. Notable locale because of a certain crappy German politician used such facilities (not exactly that one) to rile people up circa 1935.
Well, we were drinking beer, minding our own business, but getting a few looks.
An older man, certainly of the WWII generation, tottered up to the end of our table (large picnic style tables), helped by a younger man, probably his son. He stood there a bit. He spoke to us in German, which we did not understand.
Then he saluted and started crying. I’m not talking about tears, but bawling.
We didn’t know what to do, but stand and salute him back.
He then came and hugged each one of and then tottered off.
