I really don't understand how this post can be closed as 'unclear what you are asking'. I look at the details of the posting as well as the answers already provided and short of the poster answering his own question, I don't see how it could be any clearer. What am I missing?
I closed this as “unclear what you’re asking” for the reason stated in my comment. It is not a question, it is a statement of a set of facts, literally followed by “... any ideas?”
A good question will be answerable. I could easily have closed it as “too broad” or “opinion based”, as it is difficult for anyone to do anything more than make suggestions.
Any ideas? Yes - please rephrase the whole question in the form of an actual question that has a definitive answer.
Even if the OP had rewritten the last paragraph to ask if these symptoms are something that people come across often or not, I would have left it open. I closed it because after the suggestion that the question be rewritten to make a good question out of it, some further edits were made that did not improve it.

1$\begingroup$ @MikeWaters I don't agree but I have done as you suggested. Please revisit the question. $\endgroup$ Sep 8, 2018 at 18:50
$\begingroup$ Ok Glenn. I'll reopen it and hopefully make some more useful changes. $\endgroup$ Sep 8, 2018 at 18:58
$\begingroup$ Edited and reopened. Any suggestions and/or edits are welcome! :-) $\endgroup$ Sep 8, 2018 at 19:20
$\begingroup$ Thinking this over, I actually like the original question title better than what I changed it to. There is no SE guideline anywhere that implies that the title has to end with a question mark. Having said that, S9 to 20 over conflicts with his statement that the noise level never varies. I'm guessing that he is saying that the noise level varies only when he switches bands. $\endgroup$ Sep 9, 2018 at 19:36
