Bandswitch arcing can be eliminated by connecting a 10-12pf cap between  the 
80-40M positions right at the switch. Either a 1KV or larger mica or a  5KV 
doorknob works. It acts as a snubber for the very high circulating  voltage 
caused by the shorted turn effect and is something Measures never  could 
understand.



So band switch arcing is NOT a result of a parasite at  110mhz? If you  are 
right about this Carl, there are going to be a lot of deflated  balloons!  Lou
