Hi Jeff,

See the applications note on my website about chasing RFI and k9yc.com/RFI-Ham.pdf. The same ferrite cores and winding instructions that kill noise from a source will also kill pickup on the cable to the Six Pack controller. IF that's the problem.

I'm getting some RFI into my WX0B Six Pack when only transmitting on my Inverted L for 160 meters. It doesn't do it on any other band that I have connected to the antenna switch. It lights up all the LED's on the control box when I transmit. I have put several snap-on ferrite beads (the kind DX Engineering sells) in several places on both control lines to the outside box but it doesn't seem to help. Any ideas on how to fix this?

Jeff
