A rather strong / local FSK signal is at 29.200 Mc. I tried using various modes in FLDIGI to decode but no luck. It's being going non-stop for hours. Is there an app that can automatically decode the signal, this is make the choice of RTTY / ASCII-110 / PSK / QPSH / QAM ..... ?
Attached is a screen capture signal.
I am in San Diego in case some local want to give it a go.
Thanks for any information.

For a truly arbitrary FSK, or pretty much any HF signal, can recommend:

For strong, local in San Diego, suspect this is a USN transmission, which means it will likely be encrypted and always look like random characters. Not sure if that would be the primary frequency 29.2 MHz or a harmonic.

Gus,
I looked at the information for w-code and it looks very interesting. Have you used w-code with a Flex 6K? How did you interface it to the Flex 6K, IQ stream? Can you provide a ballpark price range for the software?
Thanks,

Have used W-Code with Perseus, not Flex6k. However, IQ interface seems flexible enough.
Have also wanted to try:

Think pricing today is in range Hoka $4k and W-Code $8k. Both allow you to decode multiple signals simultaneously.0
