My Cardiologist has recommended that I consider having a Pacemaker installed. After reading some of the pamphlets from a couple of the Manufacturers, I came away with the impression that they dont mi
I know nothing about Pacemakers or their RF susceptibility, but I do know a bit about RFI. As far as I know, there are two issues. One is the leakage magnetic flux from the power transformer. The oth
Put the amp in another room or seperate it from you by a grounded screen wall/enclosure....never give up the amp! Or get a Henry 8K which had the remote package as an option I believe or it was part
I have a Defib/pacemaker. The "only restrictions are no cellphone in my shirt pocket and when welding (yes welding) route the cables away from my core, IOW bring them in from the side or above (away
I don't have a cardiac pacemaker or defibrillator installed, but as part of the effort to introduce wireless electronic voting to our (New England) Town Meeting, I addressed concerns with the use of
I should have thought to suggest contact with ARRL as well. With as many members solidly into oldfarthood, they must certainly have looked into this. :) 73, Jim K9YC _________________________________
A grounded screen wall/enclosure shields only the electric field and the EM field. It is completely ineffective for magnetic shielding, and that's the potential hazard of the amp. 73, Jim K9YC ______

Potential but unlikely with a properly built amp in a steel enclosure. RF is a much more likely culprit. Carl KM1H A grounded screen wall/enclosure shields only the electric field and the EM field. I
I have had a St. Jude Medical pacemaker for a little over 2-years and absolutely no problems. My main linear amplifier won't quite make full legal power, it runs around 1400-watts. I operate on all
At work the industrial hygenists have decided to post little warning stickers on every piece of RF producing equipment including my amplifiers. They warn people with implanted medical devices to avoi
George, I had a Medtronics on-demand pacemaker implanted on September 15, 2011 and I've never noticed any problems when I'm in a high RF environment. I don't think an amplifier can cause a problem. M
Much like the Government. It's nothing more than a CYA unless they have some "old school" people on board. Like Glen I can not have an MRI. . 73 Roger (K8RI) On a more practical observation, my 95 ye
I had a unit installed in 2007. Before I agreed to have this done, I asked some friends to point to an expert. My good friend Len Svidor, W6AUG, had worked with a cardiologist (who also happened to b
Some more items for Jim's list: The main cause of "RF in the shack" is probably not the power amplifier in its shielded enclosure, but faulty shielding in RF patch cables and incorrect "ground" bondi
Hi all, I think it should be pointed out that even if you use perfectly shielded coax cable, perfect connectors perfectly assembled, and a perfect ground connection to all your equipment, you can sti
Being an old schooler myself, I tried to reason with a 'specialist'. I explained that some of the equipment they were labeling would emit far lower RF levels than their smartphone, comparable with ra
They had a mandate to label everything that was above 1 V/m which is far below the 1 or 0.1 mW/cm^2 power density that RF safety regulations from OSHA, FCC and IEEE are concerned with. There is not a
My cardiologist is rated as one of the best, if not "the" best, in the State of Texas. He is very cautious and insists on the best units possible. He did not know that I was an amateur radio operat
As I said below, You can research it on-line as most manufacturers have sites and pamphlets.and always ask your physician.. SOME of the older ones were bothered by high power HF. Some, like mine use
