I set one of my towers on fire (about 75 feet up) back in the 80s' working the CQ WW DX Contest on 160 meters. Some of you have heard this story. It's a hoot. No, it wasn't me running high power, but with a high Q system you can induce some rather high voltage on a shunt fed tower. (hi) My neighbors went nuts. It sure lit up the sky, and you could read CW from the arcs and flames.    

On a serious note, I asked Howard to review and respond to Bob. Some of you may not be aware that in addition to our formal band plans we have the "Considerate Operator's Frequency Guide" where numerous "neighborhoods" (as I call them) of frequencies are recognized, such as AM. We may need to adjust the guide. See:
