When I was in the 9th grade I built a Tesla Coil using a pair of 811A
transmitting tubes (3B28 Xenon gas rectifier tube also) putting out about 600
Watts of power at ~300 kHz. Produced a nice corona. Looking back at the
effects that thing had, I estimate I was standing in a field of about 10,000

Not to mention those still working at facilities such as the Sackville,
NB transmitter site or others like it --- VOA etc... In Sackville, I was
amazed that I could park right below one of the big wire arrays where
the control room is located. Multiple transmitters running most of the

Back in the old days -- say mid-50's
or earlier, broadcast transmitters were
required to be monitored full-time by
a qualified engineer. High-power AM
transmitters bombarded these guys with
all kinds of stuff.
Many of these old-timers reported
effects on the brain, but I can't

Lothar,
Yes, you are correct. However, my point was that the higher level can cause
issues as far as the 16 point uniformity data is concerned, and becomes
irrelevant anyway since the final drive level will be different.
Once the 16 point data has been used to calculate the required drive level
The reason for the 1.8 factor is that you are calibrating with a CW signal.
When you switch the modulation on in real testing the peak level for the
amplifier will be in the range of 1.8 of the CW level. It’s just a
pre-caution not to overdrive the amplifier.

Is it really only milliseconds? When my phone is in my desk drawer, or jacket
pocket on the back of my chair, I am aware that it is periodically active
because of interference it generates on the speakers of my PC. These bursts of
audible interference are brief - but measurable in seconds rath
