[TowerTalk] Pacemaker

[Patrick Greenlee]

I set next to my KW amp and never a problem with my pacemaker. Although 
welding isn't encouraged for folks with pacemakers,the maker of mine 
says if you do weld stay under 160 amps, hold the "stinger" as far away 
from the pacemaker as practical, twist the leads into twisted pair, 
bring the cables to the work from the side away from you,  and place the 
Gnd clamp as close to the spot being welded as possible.  Still after 
doing this your pacemaker will get significantly more field strength 
than you might expect doing ham radio.  The arc is a broad source with 
energy across the spectrum.

Check your devices maker for their specs.  They list the field strengths 
that are safe for different freqs.
