Hi Chris, Are you saying that your experience of the hum is that it is sometimes there, and sometimes not, and therefore cannot be a room mode because if it were, it would always be there?
I'm not sure that this invalidates the hypothesis. There could be a number of reasons why the hum is more evident at some times and not others. Can you be more specific?
