Mark the Ham Florida Man

Dedicated to busting the many ham radio myths about antennas, antenna tuners and transmission lines and promoting good engineering practice in amateur radio.

I am now collaborating with a contemporary RF engineer in Belgium, Joeri Van Dooren, ON6URE who is now the source of much of the technical explanations in these videos and founder of the RF.GURU website and company.

I'm a retired radio and TV broadcaster and hold Amateur Extra Class and GROL licenses. I have been a ham operator since 1965.

Please keep all comments about radio. Comments about politics, for example, will be removed.
