You really shouldn't make up those stories. They aren't believable
and they have no references for anyone to check validity.


Check with the Dallas, Tx FCC office, they can verify it.

And here is another, get some 6 year old to read it and explaine to you
so you will understand.

HAM RADIO AND PACEMAKERS
This is from Angela, VE7ANG’s Newsletter.
Richard/VE7SRB has had a pacemaker installed recently. At first he
thought he might not be able to continue Ham Radio, but after some
research he came up with the following. Perhaps it will be of interest
to others.

We have researched the literature concerning the effects of amateur
radio broadcasts and their potential effects on implanted pulse
generators. Most articles concerning the effects of electromagnetic
interference (EMI) on pulse generators touch very briefly on the effects
of radio frequencies.

We have done testing on types of interference most likely to be
encountered by pacemakers patients. One category of interference we
tested was radio frequency. This covers the HF and VHF bands from 1 MHz
to 200 Mhz. Amateur radio, broadcast AM and FM, TV two way
communications, short-wave diathermy and CB radios are in this range.
Many transmitters have large power capability. Radio amateurs are
allowed a one kilowatt input in eight bands, commercial short-wave goes
to 250 KW, broadcast to 50 KW, two way radio in emergency short-wave
regularly uses 150 watts in mobile installations. Implantable pulse
generators may be affected depending on the details of shielding and
filtering in the device and modulation of interference signal.

Testing was performed on 106 pacemakers comprising 20 different models
from various manufacturers. Testing was conducted at interference
frequencies of 3.4, 7, 14, 21 and 28.6 Mhz. No effects on pacemaker
operation were observed in the presence of field strengths less than 200
volts/meter. Field strengths of this magnitude are unlikely except in
the immediate vicinity of a high power transmitting antenna.

Overall, our testing indicates that pacemaker patients are very unlikely
to encounter problems with radio frequency fields. Certainly we would
recommend avoiding direct contact with transmitting antenna.
