Another post, this time for a signal which, having had a scan around the internet and good read up, I may have identified, but would welcome comments / confirmation.
The signal is another complex signal / what appears to he a 12 channel / multi-channel PSK system. This was received on the 27th June around 2040 UTC, on 11120KHz. An SDR-IQ receiver with SDR-Radio.com software was used. Below is the waterfall / sonograph trace together with an audio file.
With my limited analysis - I think this signal may be CIS-12 (Fire), apart from the obvious 12 channels it also appears to have the signatory carrier / tone signal just on the upper side of the signal.
Any comments, suggestions or confirmation of signal / mode would be welcomed......
Many Thanks - Good DX !
