What are these sets of signals that I have outlined either side of the screen.
The two sets are connected and I see the same thing on other frequencies VLF to HF.
I see them on radios all over the place not just at my location.
The higher frequency signal occurs immediately after the lower frequency signal, there is never any overlap.
.
Anyone identify what these signals are?

Wow! Thanks for posting that awesome link Andy.
That signal analysis is super impressive!

Re: Anyone identify what these signals are?
Thanks, but looking at the video and reading the blog I don't think it is the same thing. A variant maybe.G3TDJ wrote: ↑Wed Apr 28, 2021 1:25 pm Some information here Martin....

Re: Anyone identify what these signals are?
OK Martin....when I read your post this morning I confirmed that the transmission(s) highlighted on your screenshot were active.
At least the frequencies in Line 1 and Line 2 of the frequency table displayed in the referenced link (3312.2, 3318.2, 3327.2, 4022.2, 4028.2 and 4037.2 KHz) were all active here, though the sequencing may not be as described in the link
So many similarities with the transmission

Re: Anyone identify what these signals are?
These are MIL STD-188-110B signals and used by different NATO countries. (so MIL and coded)

Re: Anyone identify what these signals are?
Yes they are on the same frequencies, but they look different in the screen shoots. On mine you can see the separate sidebands for each pulse and their bandwidth changing.G3TDJ wrote: ↑Wed Apr 28, 2021 6:31 pm OK Martin....when I read your post this morning I confirmed that the transmission(s) highlighted on your screenshot were active.

On the YouTube video they are just a short carrier which shifts frequency as it goes through its cycle.

Are you sure? Doesn't look like any examples I can find.

Decoder sync's on these signals so...yes pretty sure

It maybe obvious to you but for a casual observer I see no connection between my image and yours.PD3LK wrote: ↑Wed Apr 28, 2021 7:27 pm http://www.kd0cq.com/2013/07/sorcerer-decoder-download/
