[Elecraft] RFI issues

[Bill Lederer]

House we just moved into, we did new under-the-counter lighting.  Once I
got the ham shack started, I saw s9 noise on 160 and 80. Turn them off, and
it becomes quiet.

Other led panel lights produce no noise whatsoever.

But now that that is identified, I will be tracking down some other noise,
likely in the neighborhood.
