Dick - I've had my K-line (K3/P3/KPA500/KAT500) running here for a while on almost all the bands, mostly CW. I have yet to have it act up this way, or any other way, for that matter. I use an 88 foot long doublet at 45 feet for 40-6 meters, and two separate Inverted L antennas for 80 and 160. Single 6 foot long copper clad steel ground rod right outside the shack window.
