Thanks to the several who have commented about this

> With the current conditions, it is really surprising. 

Yes,  the k index had been 5 and 6 for several hours before.
The band was noisy.  Not sure what my S meter read for
the noise,  but was probably around 1 or 2 on the dial.
It was middle noon hour for Nels;  but just past 7:30 AM
out here.

> What band were you guys on?  

Nels had the 20 meter Rock-Mite,  it is nailed to 14060,  or
close to it via crystal.

> What antennas were you using?

I used my Force 12 C3,  up about 35 feet.  Not sure of
Nels antenna,  but believe it was a wire of some sort,
nothing special so far as I know.  Nels reported that the
Rock-Mite is not too selective, and he was having
trouble with QRM as well as the band noise.  I was
running about 60 watts,  so that helped him a bit.

No,  at least not on purpose.  I had just downloaded the
1.357 firmware update, so whatever the "default" AGC
settings were for "slow" is how the rig was set.  I narrowed
the BW down,  but found the band noise so bad that I
didn't go much below 400 Hz BW.  More narrow,  and the lite
CW signal seemed to disappear;  it may be that I was
not set precisely on the correct sidetone pitch for the 
more narrow filters.  I was so busy trying to hear the
signal to copy that I didn't fiddle much with the controls
at that point.  It was sort of "averted" hearing (for those
of you who might also be into amateur astronomy,  hi).

Unfortunatley,  it did not occur to me to turn the 340 on and
try.  Just too busy dealing with the QRP signal,  hi.

Sure,  Dick,  I'll email you when the propagation is a bit better,  hi.

Thanks again to the several of you;  hope you don't mind my
combining your questions/thoughts into a single reply.

73 and Aloha,  Jim  KH7M
