@@horsthorstmann2480 telephony techs and some radio techs hear the tones so many times when we test something, you get a sixth sense for weird sounds like that, kind of like everyone from the 2000's recognizing the dial-up handshake sound.
Some of us are just old enough (and maybe just weird enough) to remember playing with touch tone phones as if they were tone generators. Just can’t unlearn those noises…
Remember when AT&T used to send multiplexed voice transmissions over HF? They went on until at least the 1980s. If you had a BFO on your receiver you could occasionally pick out parts of conversations if the channel wasn’t too busy. When the channels were idle, they had an AM loop that repeated something like “This is a test transmission of the American Telephone and Telegraph Company, New York, for test and adjustment purposes.” That seems a bit odd because a wide band AM transmission probably would not help that much in making sure the multiplexing and demultiplexing equipment was aligned.
The interval from @1:11 to @1:20 is a frequency-shifted version of Scott Joplin's piano piece called "Solace", perhaps played on bells and is likely a mis-tuned SSB reception.
The tones at 2:51 look and sound like reference tones for when you want to check the frequency response of a channel. I had a Duran Duran cassette that started a little like this.
04:11 Just a precision. There are no embassies in Frankfurt, only consulates (e.g., the Consulate General of the US in Frankfurt, which seems like a strong candidate for the source of this signal.) The premises of an embassy may only be located in the receiving State's capital city, i.e. Berlin in this particular case. Greetings from a subscriber who happens to be a specialist in International Law!
Regarding the DTMF tones, I decreased the speed to 0.25 in TH-cam and recorded it in Audacity, checked them by ear and increased the pitch to match. (the tones were flat by quite a bit) I matched the recording against an online DTMF tone generator. Please someone tell me if I'm wrong, but it appears to be a repeating pattern of: 0000 1111 2222 3333
@@FelixW0lf Hi, am I missing something here? What you are regarding as four and I am regarding as zero appears to have two frequencies of 1336Hz and 941Hz which appears to point at "0" (after re-pitching the recording) Or after many years of very loud music, my ears are shot! 🤣
According to what I hear, it is 1111 2222 3333 4444 - I did a lot of phreaking when I was a teenager and I memorized the DTMF tones, so I can tell them a part. After almost 30 years, I found something useful with that knowledge!
When referring to a person, German "Würstchen" can colloquially mean, roughly translated, "stupid unimportant little jerk", and "armes Würtschen" can roughly mean "poor loser", so combining "Würstchen" with "alpha" could be meant ironcally. Who knows?
The noise heard at 7:52 reminds me of an 80's toy Space Shuttle that had three buttons. One for engine noise, one for a series of beeps and one for noise similar to what you hear in the video.
The sound on 6825, im pretty sure that was a type of morse code. If you listen, there are three notes it goes to, just like three positions of a morse code paddle. If youve ever operated a very common dual paddle morse code keyer, youd know what i mean. Theres open or "nothing" sound, then another for . and a third for -. It sounds like its just going between three notes, like the three positions of the paddle.
Probably completely irrelevant, but the Atom Alarm tones sound incredibly close to the sound of a Farfisa Professional (electric) Piano being played through a ring modulator exactly like Irmin Schmidt, the keyboard player from the German band Can, used to do. He had a custom built signal processor made for him by Alpha Electronics of Zurich, Switzerland, known as the Alpha 77. There's a track on Can's 'Landed' album called 'Vernal Equinox' and this sound can be heard very clearly at around the 5 minute mark as well as being constantly in the background throughout the track. (This rather odd sound crops up on a few other tracks on this album as well.) Can were known to also known to mess around with shortwave radio transmissions, integrating them into their live performances, although this was a little later in their career. Anyway, as I said, this is probably irrelevant, but it sounded uncannily (no pun intended) similar and I couldn't resist mentioning it...
I wonder how many, who are responsible in some way for these odd transmissions, are still out there watching your videos? Just as they're about to click SEND in a PM telling you all about it when, at the last moment, they decide, "No.....better not," and click CANCEL?
The Trumpet reminded me of the Drums and Trumpet numbers station of some years back. In the last clip if you listen carefully you can just make out what sounds like a Broadcast transmission. Was it Audio from a Transmission using the same site as the doorbell transmission,in,? I know the Cuban numbers station suffered from breakthrough from Radio Havana, suggesting the numbers station came from the same transmitter site as Havana.
My guess is things like the doorbell are using a "known sound" not only as a channel marker, but also as an audio tuning marker as well. it would be a reliable way to know that you are receiving the signal correctly and at the correct pitch.
I remember hearing back in the 1970s between 20 and 10 meters or so a signal which sounded like a sequence played on bagpipes which was about 12 notes long repeating over and over. Occasionally the sequence would have a few notes different or it would sound messed up like a tape had slipped off capstan on a reel to reel machine. It wasn’t an international broadcaster tuning up because it occurred outside of the international broadcast bands.
6.623 had some weirdness last week, but try as I might, I couldn't get a coherent rx . Strong signal into north Wales. Best I could decifer was "bitty" English. Kenwood R 5000, and a Yaesu ft-920 with filtering and DSP. Gave up in the end.
Regarding Atom Alarm - I think the music is a highly distorted version of a sequence that Kraftwerk used to play at their shows, only that I can't find a recording of it for the life of me. I suspect that "Würstchen" is in fact "Werke" with a lot of noise and clipping. EDIT: Someone else says its The Leo Hassler Synthesiser rather than Kraftwerk, so my memory could be playing tricks on me.
Good call on Kraftwerk, is it possibly “Transistor” but shifted down by the SSB distortion? Seems like the tempo and the rhythm matches. Whatever the song is it has been stuck in my head since first watching the video lol. th-cam.com/video/ccXX-QwJnTI/w-d-xo.htmlsi=CYT5s8oHXn0BxRVq
