Pretty interesting Don. Thanks.
You have quickly upped your game. Moving way beyond just listening to
scratchy noise on a single channel of a VHF or SW receiver.
I noticed that you are wearing a safety vest - looking like you are an
official or utility guy.
If you send the homeowner a link to your video - I'd call his house
something besides a "suspect" house. Maybe "source"?
Thanks again.
