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.
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?
Regarding the DTMF tones, I decreased the speed to 0.25 in RU-vid 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!
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 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 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.
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!
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.
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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ccXX-QwJnTI.htmlsi=CYT5s8oHXn0BxRVq
@@inigo4688 Music is entirely destroyed by SSB unless it is tuned exactly. I remember a shortwave broadcast that was donation funded and was using SSB to save on the electric bill. It sounded really good until they played music, the song could be "happy birthday to you" but it'd be unintelligible unless my receiver was tuned dead on.
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.
I don't think you'll ever get a music match on the first one as the SSB is so far off frequency, I don't think any music checker, Shazam etc would tolerate that as it's not something that would occur in 'regular' recorded music.
@@paulsengupta971 I did get to find that with google, however I was more talking about the frequency error in the recording wound be too hard for any auto recognition
I personally find the Atom Alarm more funny than unnerving. You just can't take that seriously. That drumming part (if one is to call it such) could make up for a MFSK of sorts, if you let your imagination run wild.
i remember in the late 70 or early 80 hearing a morse code signal repeated over and over. i can still remember the sequence, I think it was on Short Wave but could of been on Long wave.
@@numberstation Wow Yes that seems to fit perfectly!. I may have a recording of it on an old tape somewhere, but all my tape drives have suffered with belts breaking so can't search for it. Perhaps my next project. That's really great that it was not just me that remembers it. Do you have any info on what it was or for?
@@maxusboostus I think they’re Non Directional Beacons used by aviators for navigation, I remember another one that sent - -./-../- - around the same time. Strange how these things stay in the mind for so long!
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.
I do not have recording, bot 2.5 years ago, at 7am, around 1400khz AM Radio (no local channel) I would hear PSK8 (I think) radio near Garden Grove BLVD and Edwards in Westminster, CA. I posted several inquiries about it. I thought maybe it was the 3rd harmonic of a 630 Meter Band station that was local to me. At the time, 2.5 years ago, I didn't know what the signal was that I heard. It was none of the modulation I knew of.
Nice to see Penmon in a video, does this mean it's going to be the subject of its own video soon? Or you gonna pick on Llanddona and took detour to Penmon on your way? Either way, bring it on!
Just one of my wacky observations, the PSK8 sounds remotely like what is on the intro of the Propaganda song P-Machinery - obviously it is unlikely to be the same message, but similar sound. Also it was in 1984... not sure how old this mode is.
