Ron & All:  Just a handful of XND decodes on 75 kHz in the prior Thur early morning session. Past 4~5 days prior QRN was high and geomag condx

prevented overnight  XND reception,  Last night first XND decode at 0600 UTC at -27 on my e-probe , but 120hz harmonic QRM present and wiping out XND.

Switched to NW EWE at 0644 and immediately picked up WH2XND with an addition 53 decodes through SR.  Somewhat odd at the prior 2 months the 

e-probe consistently beat the NW EWE antenna (lowest noise West direction here) antenna. Often times in the past 2 months I could not decode XND at all on the EWE antennas,

but would have decodes in the low -20s on the e-probe.   I'm uncertain if the 120Hz harmonic QRM is was seeing was local noise or modulation products from the nearby

MSK stations.  Ron mentioned he may be switching back to 137 khz tonight with the rising QRN situation on 75 kHz band...
