BPL-Busting Modes/Techniques
The Digital Voice formats presently in use by hams are not designed

well. Time ending the tests was about 0155Z here in SW Wisconsin in the
U.S.
One of the questions that I have is how do you determine where to set

I was listening at 0100Z and heard ALE tones but so far nothing on
DRM.

I will be calling CQ at the top and bottom each hour for
most of today. I will use 14236 if it is clear with 14233 and 14239 as
alternatives. Perhaps 7296 after 0100 UTC. I will send an autoCQ text

good enough.
Is your soundcard new too? You probably have a soundcard with
drivers that don't quite have the same sampling rate for tx and

frequency is correct. For rec

Can anyone help? I didn't
