Re: HF Magnetic Loop and Pacemaker

Morbidly funny John, but really, a good point. Some info on at least one brand of pacemaker (the one I have).
I too have a pacemaker. I often run 500 watts and one end of the 160-80-40 meter antenna runs right over the shack, about 3 feet above the house roof. My pacemaker is from "Boston Scientific", has bluetooth connectivity to a remote monitor that lets my cardiologist know immediately if something goes wrong with either ME or the pacemaker. I'm on the air almost daily for at least one QRO contact on 40 meters and in over 12 years, have had no RF episodes with the pacemaker.
My Boston Scientific rep said the main thing to avoid is high magnetic fields as a coded magnetic signal is used to trigger diagnostic mode in their pacemakers so a Mag Loop might be a different ball game entirely. I don't have one here but then I have a 40' telescoping vertical that collapses down to 3 feet for my portable operations when I even go portable anymore - LOL.
That being said, I agree with the need to use CAUTION when operating close to radiated fields of any kind when one has a pacemaker implant as I'm sure the manufacturers all use different RF and Magnetic exposure standards from each other and results will surely vary. Best to err on the side of safety.

Start with 1 Watt, then go with 2 Watts, etc. If you die, back down a Watt (hi).
