sosunds like you may have power line noise which wont go away, but may
vary with weather.
I had similar problems which I tracked down with an AM radio, and
driving along the roads around my house til I located the likely
culprit, a continuously arcing lightning arrestor on a pole about 0.7
miles away.
I called the utility and met their crew at the site. Turns out the
problem wasnt at the pole I thought it was, but one pole over. The
utility crew heard the arcing and changed the arrestor. No more
problems.
Arrestors can only take so manch discharges. In my case, it didnt
clear, and remained steadily arcing 7/24. That costs the utility $$$
in wasted power, so they were happy for me to help them find it.
