[600MRG] condx 20-21 July

[Larry]

Early last evening the usual signals form WD2XSH/20 and VE7BDQ were 
weaker than normal but built up fast. Lots of QSB with variations 
between WSPR TX periods of 20 dB or more at times. These unstable 
conditions were observed until 10 PM local time when I went to bed.

As usual, I switch the RX phased array from westward looking (for BDQ 
and /20 daytime) to eastward. The overnight logs seemed to indicate 
unsettled conditions. Some of the usual suspects were present in both MY 
TX and RX logs but were in and out.

My Great Circle Bearing to New England is somewhat northward, and 
actually passes through the aurora influence zone. This makes for rather 
unpredictable propagation between me and stations east of the 
Mississippi and north of the Mason-Dixon line.

I have seen this repeatedly on 160 meters over the years and it seems 
630 meters is no different. It would be interesting, I think, to run a 
lot more power and see if more reports would show better prop detail.

Of course if more stations would run WSPR overnight at least, that would 
help.
