Hi Wolf
 
I thought it was selective fading but the lower was always better over long periods (2 hours) but has been strong here now and appears to have equal side bands now. It appears variable....... confused! Accidental Phasing SB TX ?
RX here using TS690s with both filters (250hz) in and also using Winrad with the RX in wide IF mode appeared to be the same result.

Hi All
 

 also NDB "BIA" 474 Rzeszow / Jasionka at 1000miles better Lower sideband than upper sb?

ah, confirmed...  I thought I was the only one where "BIA" showed this behaviour. First blamed it on my receiver's passband, but then noticed the same happened with a Perseus and an SDR-IQ. But I think they add both sidebands 'synthetically', not with an old-fashioned AM modulator (with audio modulation transformer or similar).
