>>> WSPR-15 on 2200M here tonight.

Who knew QRN would be so bad today.  Yesterday, I have no doubt the lower 
power and QRSS10 rate would have made it through just fine.

It would appear that the same groundwave propagation that makes signals so 
good out to some yet-to-be-determined distance on this band also conducts 
static the same way, given where the storms were relative to me today.  With 
a little more distance from the storms and a little less distance to the 
sending stations, for instance, Garry in Illinois was doing much better with 
the available signals, also on an omnidirectional antenna.

And, I noticed the daytime groundwave static seemed pretty much limited to 
LF and VLF.  It was a consistent level from 30 kHz (the lowest I could tune) 
up to 200 kHz, then began falling off somewhere between 200 and 300 kHz, and 
was almost non-existent at 630 meters.
