Hello All,
I am still working on this issue. What has been figured out is the
microphone circuit appears to be the victim, in a round about way. If we cut
off the microphone in any way the audible failure goes away. If we mute the
phone it is linked to the failure goes away. The call box we use
It may be worth noting that in the medium wave broadcast band the FCC limit
is over 600 volts per meter. We don't incur inherently harmful induced body
currents with less at these frequencies -- unless we're hanging onto an
antenna.
But considering the low potentials to be measured, and the

Greetings all,
I wanted to run this by everyone to see if there is some consensus out there

But there is a very big difference between the two fields Mr. Cuthbert cites,
aside from frequency. The cell phone field likely has a field impedance close
to that of free space, because the antenna is a good match to the transmitter.
Unless your tower is around 100' and operating as a base fed
