Hi John, 

I fired XNI up on 185.296 at QRS20 to give you something to listen for. I'll run it for a few hours while I'm mowing the grass !

While working on the fence row with the tractor yesterday, I let the CR-1 do 
what it does reasonably well...keep a watch on HF. HiFER reception has been 
poor recently, but there were hopeful signs at mid-day yesterday. NC and EH 
were fading in and out over roughly 3 minute cycles, and no SIW yet, but 
every so often I could see MP in there too, so I had hope. I turned on 
captures and went outside to work. 

At mid-to-late-afternoon, there was once capture showing a single very 
strong upstroke of SIW slant mode--nothing before, nothing after, just that 
one slope! Meanwhile, down about 13555.3, there was a complete set of WM 
IDs on screen. By late afternoon, SIW slant faded in abruptly and WM was 
consistent for a while. Then, equally abruptly, the ionosphere kicked in 15 
or 20 dB of attenuation on the path from Elgin, IL, and a minute later did 
the same to WM. That result can be seen here:

Everything at 22 meters seemed abrupt yesterday, in fact. Codar seemed to be 
switched on and dominate everything for a while, and then attenuation would 
be switched in again, leaving it just a mild clatter. 

Today I'm on my way out to listen for daytime LF with the Kenwood, if the 
thunderstorms on the Nebraska-Iowa border aren't too noisy.
