Unknown Radio Signal on 3830Khz USB Wide Band
Posted on
Recorded on 11 Dec 2009 about 23:56H UK time. 3 distinct signals of unknown origin. A repetitive tone that may/may not be related to the other 2 signals; A multi tone burst which I cannot identify as MSK or PSK or any other standard data burst modes, and a Noise Burst that resembles a transmitter being keyed on/off manually. I would really love to know what these signals mean or what type they are and if they can be decoded by anyone other than the intended recipient.

@llinkz the signal is not tuned right “agreed”

one day you will encode it as the speech of adolf which is a encrypted plan for a time machine.

@JohnnyX50 Perhaps the West could win the war in the Middle East by creating a massive radio garage door opener.

This net is from German customs
8-tone MFSK is MIL-STD 188-141B in ALE procedure (ZLST & ZHEL stations establishing a link)
then the 2400Bd short bursts are from a Rohde & Schwarz modem sending datas
btw the signal is not tuned right

ALE transmission with ARINC,If you are in Europe,this is military’s transmission in other country thats possible it is ham radio trafic

@JohnnyX50 the garage door opener part was just a joke. relax!

sounds like a scrambled – encoded burst. Could be Army special forces. Could be Scully & Mulder out in the field. Who knows….

@vidPRODUCER1 Its Mil Standard ALE broadcast
so probably very much the same thing you got up to. Garage opener ? well, quite possibly any radio controlled device would sound similar, as its all data bursts encoded as tones, however this is not a garage opener, not on shortwave lol, unles someone has a big antenna in the mid east opening the door for the missus back home LOL

reminds me of burst burst transmissions like they used in nam. they hooked anantenna wire to a chopper and he would climb up and then they would do bust transmissions then bring the helo back down when they were finnished. but i could be wrong. could also be a garage door opener for all i know,,,,lol i dont know squat about radios. i just saw them to do that. sounded pretty much the same

That is a fax macine

It is RTTY

this is the sound of the frequencies communicating to the sattelites

definitively a data transmission. first noise is handshake between the client and the host, then transmission. finally the disconnection signals.
there’s a 1s 400hz beep every 12 seconds for the sync. that means it’s designed for an old, or cheap / primitive electronic device.

I have no idea about radio, and I like it, I am fascinated by this, kinda mysterious for me.

Amazing !!!

Hi everyone.
First ist Mil-ALE broadcast. Then is Highspeed modem. Not decodable. But ALE calls are from german duty. Note: 80m band is not exclusive for ham operators.

@LikeAVideo The Spectral output is from Spectrum Lab, the sound is recorded straight from my radio via the PC as a wave format file. I then played the wave file back and monitored the output on Spectrum Lab and used Cam Studio to grab the screen as AVI for upload to Youtube =]
