[Lowfer] WSPR-2 on 2200 m AND 22 m

My 24+ hour monitoring of 2200 m continues, but with things stable at
local noon, I thought I'd check on HiFERs for a few minutes.  I ended up
spending more than an hour there because of discovering (for no evident
geomagnetic reason) the first opening in many, many months over the
relatively short path to Illinois.  SIW's signals in slant mode and WSPR-2
were both present!  The spots continued through Codar QRM until QSB
started punching holes in the timeslots that were too large for decoding.

As for 2200 m, I uploaded the rest of last night's and this morning's
captures to WSPRnet earlier this afternoon.  Signals were so strong
overnight that IM distortion in the audio chain produced a lot of false
decodes of XXP and XND on spurious frequencies, which I filtered from
ALL_WSPR before uploading. That ended right at local sunrise.  Signals
were up to S7 last night, and between S2 and S3 during the day so far. 
Negligible QRM today, and not too bad last night.

After the excursion to 22 m this afternoon, there was an unexpected
additional delay in returning to 2200.  I plugged the R-75 into my spare
storage battery and--nothing!  Plugged it back into the first
battery--still nothing!  Fortunately I had my #3 R-5000 ("Old Drifty")
with me, and even though it also did not work with the second battery, it
did with the first.  Peculiar, considering that the spare is also powering
the computer successfully, but I didn't have the DVM with me to perform
any diagnostics. Will have to do that later.
