[CQ-Contest] SO2R 2nd Harmonic Reduction Question

[Ken Widelitz]

After having my XYL flip circuit breakers while I was watching a bandscope,
I found that an A/C unit on the roof was causing an increase in 2nd harmonic
interference. Any suggestions for how to deal with this besides flipping the
breaker off during contests? I can't wind the power cable around ferrites as
they are fixed in conduit.
