I'm wondering if anyone has seen an RFI source like this before? * At isolated (and generally short) periods, the RFI is gone. * It has two modes... * Mode A - like the pattern from my first RFI Hunt

Horizontal sweep noise from a nearby TV. Actually it's 15.75 kHz and so full of harmonics that it carries well into the HF band. It couples with the cable input which acts like an antenna very nicely
Randy, Thanks but I don't think that's it... The signals are measured at 18 KHz apart using my Flex 5000 - the signals start somewhere around 1.7 MHz (tough to see them lower because of the AM band)
I have something similar that I can now see with some new software and my QS1R - only mine are ~80 KHz apart, peaking about 2.2 MHz, and are broad. I'd be glad to provide spectrum scope pictures to a
