On for a minute or two then off. DSB, suppressed LSB. S9+10-20 here, great wide audio. Mix Radio?
Carrier now at 0255z.
Off, then music back on DSB at 0257. Smooth chill jazz fusion sorta stuff...then off again, QSY'd to 4140. on and off and on and off and still off...
Back with 13kHz wide USB 0318 - up to 15kHz wide, but signal is more around S8-S9.
Back to +20 at 0323. Sounds excellent, but maybe a little bit much on the highs.

In looking at the waterfall the highs are equal to the lows keeping all frequencies at max modulation with out distortion. This is what broadcast stations do. This pre emphasis on the hights helps them get through during fading since they are the first to be effected during a signal fade. What I do is turn the treble down a little on my SDR receiver. You can do this if you are using a HI FI amplifier hooked up to your SDR. By the way you had a excellent signal of the station. Thanks for the waterfall image too. Great catch.
