but I specifically asked in the question if there might be a better stack where the question might be fit for migration.
Not our problem. Off topic here is off topic here, whether we know of a better place for the question or one exists or not. We are not the help desk for the SE site or the rest of the internet.
Apparently the community decided there wasn't.
More likely they didn't want to encourage people coming here dumping random questions on us expecting us to tell them where those questions really should have been asked.
We are here to discuss electrical engineering, not how to use the internet.
Anyway, while the only existing answer did provide some interesting information, it didn't really answer the question (see the edits for the resolution).
I didn't see the question originally, but what Spehro said was the first thing that went thru my mind as I was reading your symptoms. It is actually a very reasonable answer to the information you provided.
My meta-question is if I should just delete the question, since the community decided it was off topic anyway. Or leave it, since the existing answer is very interesting.
I'd rather delete it myself, rather than incur the negative rep and black marks of having the community delete or close my question.
I'm not sure it works that way. I believe the algorithm that checks your posting quality and suspends your posting privilege if too low is not fooled by you deleting low quality posts. In fact, I think that makes things worse.
You probably can't delete it anyway since there is a upvoted answer. Put another way, you have no right to delete Spehro's answer, which is what deleting the whole question would do.
