Thanks to those answering my request for noise reduction
sources/sites. Several pointed out the distinction between heterodynes
originating in the receiver and noise external to the receiver. I was
careless in the wording of my original post for which I apologize.
Since a picture is worth many words, I'm included a screen shot of my
panadapter tuned to 15m [see below] with the "noise" spikes clearly
pictured. I have not tried the house shut down with the radio
operating off a battery. Other time demands, but will do so shortly.
I'm sure that will be informative. Interesting that the spikes occur
only in the vicinity of 15m. They gradually diminish outside 15m until
they are completely gone by 20.000 and 22.000 MHz.
