Dear Warren, LF Group,

I monitored 137.78kHz last night - I got up around 0200 to see how things= were doing, but dense =A0QRN activity in the Baltic was causing a "w= hite-out" of the spectrogram. So I diverted the output of the phased= loop/vertical combination I have been using for 500kHz WSPR reception to= the 137kHz receiver, and re-adjusted it to null the QRN, which gave about= 10 or 15dB improvement, and good copy of your beacon between about 0220= and 0340, when signals faded out. At the left of the attached image, the= bright patch shows the appearance of the QRN "before" the phase= d antennas were used, the rest is "after".

BTW, the 500k WSPR antenna is back to normal now...

Cheers, Jim Moritz
