Good demo. To that cause, I'd like to share a true experience that happened
to me as part of a group of Explorer Scouts on Field Day one year. I was an

Mike,
A point worth mentioning I believe, is that a static drain resistor placed
inside a transceiver/ transmitter/ receiver as you suggest will provide some
protection against static should an external static drain resistor fail into
an open condition. Certainly good practice IMHO.
