[RFI] From: [irca] Strange RFI

 Anybody do the calculation/measurement on what the inter-spike frequency is? 


Looks like the switching frequency of a switching power supply.

Could be anything today, including an EV charger perhaps blocks away.

Peculiar RFI I've not seen, or heard before.

Ideas?

Wondering if anyone has seen any RFI that looks like this.

https://spacetubes.com/DX/Digital.RFI.Lower.AM.Band.End--2023.Nov.14--sdkaz--perseus.mp4

The first link shows it starting up, then it goes like that for a while 
(sometimes a long time - half an hour or more), then it ends like what's 
shown in the second link,

Then it can be quiet for a random amount of time, before it starts up again.
