I didn't mention the most random item yesterday -- I sat down and fired up my amateur radio transmitter and a few characters in, I heard something start to beep. When I stopped, it eventually stopped. When I started up again, it began to beep after a few seconds...!
Finally tracked it down to the (obnoxiously loud) gas/CO detector in the dining room. It's about 20 feet from the open-wire balanced line (it looks like a rope ladder for the Wee Folk) that connects to my antenna, and it does not like shortwave energy, not one little bit. So it got a little vacation.
The sound is oddly nondirectional; while it is loud enough to get one's attention, it does not localize well. Tam was on the porch while I was hunting the beep and remarked, "Oh, was that in the house? It sounded like it was across the street or something." That's kind of an alarm fail, if you ask me.
IT'S A KLUGE
