[Elecraft] Mobile high power

[David Wilcox]

Eric,

You might let this one through.

Ed Eklin, K8ZZ, is 300 counties shy of transmitting from all counties in the 50 states. He drives Hondas.  He is available on QRZ and enjoys questions.  He has learned how to transmit with his K3, KX3 with 100 amp, etc., over the years without having any auto related computer issues. He just gave another great lecture at our radio club explaining the grounding issues with mobile operation.
