[Lowfer] Overnight WSPR decodes

JB: I took a peak at your overnight captures with the wspr database search 
tool and you had quite a few XND captures last night....

The other evening you were copying XIQ through all the QRN when I could 
not....interesting how the propagation moves around at 630m.

Made a few EAR captures yesterday afternoon as antenna checks after 
connector maintainence.  In QRSS30 slow mode EAR shows some
dog bones....

EAR signal about the same on NW and NE antenna legs as well as omni mode 
(EWE unterminated), not much more than 1 dB change.  Switching to SW 
direction EAR goes into the noise.

I dont think my F/B ratio is that good (~20dB seems unrealistic), but I did 
notice my background noise to the SW was peaking -54 in Argo QRSS30 slow 
versus -60 to -62 when pointed NE. So apparently a combination of 13~15 F/B 
ratio and several extra dB of broadband noise would cause my rx to only 
detect noise to the SW...

Not sure if that result is a local noise source or the EWE antenna looking 
into "hot sky" across it's elevation angle pattern at mid-day.....(2 pm 
ish)....
