But ours is an RFI generator. I put several ferrite cores on the AC power cord.
Knocked it down, but still mildly present. I can tell when it's running on my
SDR. The trace is quite obvious.
Sorry to run contrary to the Bosch/European train that we had going here.
Thanks for that input, Scott. Did you just clamp ferrites onto the ac
cable, or did you wind turns through ferrite cores? Clamp-ons without
turns don't do much at HF, they are designed to work at VHF. Here's a
tutorial applications note on that topic.
