19:35 rasping QRM on LSB. miki.

Seattle, Sunday evening, 5755 kHz was S9 and in the clear at 7:00 PM
and up to S9+10dB at 8:15 PM, PDT.

I was picking up some crud at 5749 this morning, but my noise canceler
box, with a short antenna, cleared it out, so that's a good indication
that it was my or one of my neighbor's computer gear.

My last visit to Oakland had some hours had a
S9 Noise Level across the Bands below 10 MHz.

My next door neighbors kids had a Band practicing
in their backyard garage. Their Amps and Equipment
were the Source.
* Three Reversed Two Prong {Only} Electical Outlets
plus they were using a Power Strips with the Round
Pin Cut-Off - Rewired the Outlets with Three Prong
Receptacles and gave them two new Power Strips.
* Installed Snap-On Ferrite Cores (10+) on all the
Power Leads and Equipment Cables.

This dropped the Noise Level down to below S3.
