 No Info on the duty cycle, don't know if it was related to sometimes the 
thing zapping to the edge of metal door on it's way out. Electrostatic 
bleed off maybe?

I agree that there would be no resonance effect on that band and the AM 
radio was simply detecting static bursts. AM radio was not intended 
receiver of noise, it simply got noticed.

No, the X-ray tube was the rectifier. The pulser was an ignitron system 
with sync to line frequency and a divide by N setup. Rig turns it on, 
edison turns it off at the next cross-over.
Also, this may be of use to you; After reading your other post INRE the 
fair weather polarity and the TC rectified polarity, I asked Bob about how 
the DC was steered to the tower because you had a good point there. The DC 
was negative to the tower. Half wave rectified. The RF system was keyed at 
~7.n Hz.
Were it me and given the conductor sizes (600MCM primary, 2 turns in 
parallel), #6 secondary and  #4 on the extra coil, I wouild have figured 
well, plenty of room, need lots of current, make it a CW machine, use CU 
tubing and water cooled so it does not melt induction style, use a CQK-650 
tube (1.77 MW CCS, VOA uses them) real rectifiers in oil.

You would think so, would be nice but while it made lots of X-rays, it was 
not blazing a path like you described. Mostly useful as rectifier. It never 
worked breaking down the air as he was told it would with X-rays.
These days, a UV laser is easier to do anyway.

There was a ULF receiving station but I do not have this data of distance.
The AM radio heard noise spikes, why, unknown. Maybe one of the metal 
buildings or parts thereof had a lot of power sucking off the system and 
formed a electrostatic elaxation osc from it and the tower. Enough cap and 
you can pulse megawatts low rep rate.
10's of miles, even with pulse mode is a lot of ERP. That's why I think it 
had to be a secondary emision related to the DC pulses, ~37 kHz Vs ~ 550 
kHz is a lot of harmonic atenuation
I've done enough AM Broadcast Monitor Points and full proofs to know better 
than that.
Also that general terain is not exactly AM broadcast friendly from a ground 
wave point of view.
Perhaps the re-radiated noise was riding the high side of the local power 
grid, carrier current style.
That's all I have.
