New digi mode on 4207cf ?
« on: November 06, 2020, 1207 UTC »
Any ideas?

I'll try to get a wide bandwidth recording but not having much luck as yet.  I think it's transmitting at top/bottom of hour.  This was captured @ 1200z on 11-6-2020:

Hi.

By any respect to the usage of SDR it would also a great opportunity to add a soundfile, as it also helps to identify a sgnal.

Kind regards.

The best place to post questions like these is the Utility DXers Forum reflector on groups.io.  They have a lot of folks that can help with digis like these
