question about amateur mode

 

Maybe I never noticed this before, but during my tuning around with the SDR, I notice an apparent communication mode and I'd like to find out what it's called.? I hear it on the lower part of the bands, not up where voice is.? If I listen to it on USB, for example, it is a series of closely spaced tones and they almost have a musical quality.? It must be communication because one series will stop and then another will start, but the tones will be slightly different.? Can someone tell me what this is called?? Thanks!

Olivia possibly. If you do a search, there is a website that will help you ID various modes. Also Ham Radio Deluxe will auto detect most digital modes.

Thanks for the info, Chuck, but appears to be FT8.? Looks like a relatively new mode which is why I guess not recalling hear it a decade ago.
