I just noticed something I believe is new to my local RF environment. It seems to start around 15MHz or so and is prominent all the way to the end at 30 MHz. The "signals" are at roughly 60 KHz intervals.
I also notice a bit above 12 MHz another anomaly that produces a "kerchunking" sound pattern with a repeat cycle for the pattern something less than one second. I have attached images for both things, which I guess could be related, but I have no idea what might cause these.
I disconnected the antenna to verify everything disappears. I have a new UPS in the shack (not powering the Kiwi though) and this is the only thing I can think of that might be "new" in my environment.
Does any of this ring any bells with anyone?
