Re: LF: Re: WSPR 137.0k

Hi Jim, LF,

 

your WSPR on 137.0 kHz was received fairly well in Nuernberg throughout the night. Often the SNR in the QRN appeared marginal even though the trace on the grabber screen looked quite good - this is due WSPR fed by linear audio containing all the impulsive noise, whereas the SpecLab screen did have the software noise blanker engaged.

 

The frequency incidentally suits me well as my grabber receiver is sitting on 135.5 kHz USB anyway, eliminating the need of another frequency conversion and a second PC running WSPR. I'll just leave it like that for a couple of days, so any possible spots between 136.9 and 137.1 will hopefully be uploaded.

 

Best 73,

Markus, DF6NM

Dear LF Group, 
 
Thanks to all for the overnight reports/decodes. I also set my RX to listen for WD2XES on 137.577k, but no decodes here - perhaps not suprising considering the level of QRN! 
 
Cheers, Jim Moritz
