[Lowfer] WD2XNS QRSS45 on 137.781

[Garry Hess]

Jay, your daylight signal is coming in fine to the west, along with MP. 
But at my usual sensitivity/contrast ARGO settings (6th tick) I'm 
getting a lot of spurs from my lowfer. It's 23 miles away, but daytime 
levels are usually around 35 dB SNR (Spec Lab, QRSS3 BW). That impacts 
my e-probe more than the Hifers I run on 13.5 MHz, one of which is just 
20 feet away! I can null SIW with a 3' loop but that antenna is much 
less sensitive than the e-probe, at least on ground wave today. Backing 
sensitivity/contrast off one tick (5th tick) gives a"quieter" display 
with the e-probe. When both MP and XNS are keyed, SIW artifacts still 
are visible (along with LSB IM3), but the "wanderer" is hidden in the 
noise floor.
