[RFI] 40 Meter RFI Issue

[Michael Coslo]

It’s a Flex6300.

Nothing has changed in the shack since the day I got it, and through the winter, 40 meters was in pretty constant use, and was working well until around a month ago, when this interference showed up. I’ve done everything locally except for turning the entire house off. Which is a little difficult to do with the 6300 because it runs through the house router and has a computer attached.

I also see the interference on a little RXTX ensemble I built that I use outside the house. That might be the ticket for turning off house power, since I can run the RXTX off a battery, and same with the laptop attached to it.
