Back In my youth I lived in this little grandmother cottage (converted garage)
behind a house in San Jose. One day, after I had been on 75 meters the

A few years ago I was up late at night and decided to send a couple of

I had two tough controlled reading lamps in my bedroom. They didn't
cause rfi but they changed on/off state each time I transmitted.

To start with, visit the neighbor and explain the problem. They will

touch-controlled devices, and the answer is yes, then you may be able to
get them to unplug or temporarily power-down any such devices to see if
the interference stops

for the switching action. Basically the lamp has a
free-running oscillator that is "detuned" when the lamp
is touche
