I’ve been double-dipping into this SSTV mania this weekend… I FINALLY got my improved coax for my SatNOGS station, and I wanted to compare against my portable Yagi setup. This morning, I get a WEIRD interference on both collection systems. Below are a series of Observations, the first one is the “normal” environment before the mess, then the messy ones, and then the first obs after the mess.
Listening on my FT818, it was mostly a background irritation on FM… clicking. But on any AM mode, it was a couple tones… like morse, but just Dit’s. And regardless of where I spun the dial (from 420 to 437MHz), the tone never changed… tone. You know how morse is a lower or higher tone, depending on where your dial is? This tone was constant, making me initially think it was inside the receiver, until I pulled the antenna off and it went away. And then noticed the obs at the same collection time frame had this interference.
I have an audio recording I can probably share when I get back home, if anyone is interested in that weirdness. I mean… beeps. Exciting…
Anywho, I figure it’s probably something electrical in my house or a neighbor’s house, but I wanted to toss the question out in here, in case someone else has seen this before.
(And before you ask, the Yagi system was on battery, so not a house-ground issue. I pointed the yagi in all directions and I didn’t detect a strong/weak pattern… and being on the back deck, I was kinda expecting SOMETHING. And it went for three hours… that’s quite a while.)
I appreciate any advice, wisdom, or shared befuddlement.
