@Earl & Bob, & All,

Sorry for the progress slow down.  I've been freaking out.  I am a scattered mind, but the fragments replay constantly and build into bigger facts and understandings and things I must answer for myself.  This is deep with distraction.  I've spent more time worrying about which to do than trying each to see what is what.  I am sorry I am so slow to get RMF.

I promised more Scope shots of the pickup and I will deliver, however I have little time to do side tasks that are not related to getting RMF.  I noticed the 'interval' acts like frequency.  I was slow to adsorb what I saw.  At lower freq's, I saw 49% duty cycle have these hump / reflections off Secondary ends unless I shorted Sec'.  At 51% duty, they vanished.  At higher freq's they came back to >50% d-cycle.  I will document better next Scope shots. 

I seem able to make only 25nS pulse widths when I tested Dirac's Delta Function high pass with a Tektronix 465 100MHz Scope with 100MHz 10X probes.  Same setup now shows me 50nS width with OWON 25MHz with 60MHz 10X probes.  Back then, I did side by side HCT Vs ACT and saw that HCT hit Vcc, ACT hit only 3V.  I retried all last night and verified that the MIC4427 input high thrshold is 2.60V and ACT seems able.  However, I see that the high-pass filtered spike HATES decouple Caps at all on the MIC4427.  Changes perfect spike shape to spike with shelf on back end.  Yes I need to show Scope shots.  I will next post.

Why was I distracted with this?  High-pass pulses are the only clean pulses I have been able to make.  My square waves ring from fast switching just as they did on critically fast ECL PCB's I once worked on.  Speed = ring.  The high-pass need only stand up to high voltage to be better. 

My Prim's are 5.655 m long and I hear loud and clear that pulse should cease before it reaches end of the Prim.  Open-ended, I see voltage applied yields non-linear results.  More in yields much more out.  I test high-pass on MIC 15V output next then try to tune open-ended agian with cleaner pulses so that the Longitudinal component may at least be made to resonate. 

Now I see what the very fast and strong Diodes are for.  These would protect the high-pass from standing waves.

It seems that the complex ringing impedes the Longitudinal sinusoid from forming fully with shielded pickup.

This powder toroid 4/2/1x recipe may not be ideal, but it serves a purpose I know. 

About the HV Bias.  I need to test more, but it seems that DC produces no voltage gradient and that is what is strange in the static voltage divider.  A changing voltage may be required.  Modulated.  Like my handy SM-10 1000V Power Supplies can do with their 0 to +5V input controlling 0 to 1000V VDC out.  Don't know frequency response yet, but I hope for 60Hz!  However, taking Secondary out with just HVPS Cap resistance, and blocking Cap, I have to short resistance to get Blocking Cap to charge, then when I pull short, they never equalize.  Weird.  Kirchoff again?  Will post data later.

Flux cancellation.  Phase cancellation.  At lower resonance band, 2 nodes, 1/4 wavelengths assumed, I am not sure.  If so toroid is acting as if circumference is way bigger than it is.  2.3GHz wave fits circumference.  One freq, open-ended is FM jammer in 98MHz band.  Strange.  If I search the jammed freq's in FM from 3MH drive one Prim, I am sure there is learning to be done. 

The pulse width interval is the active portion of pulse and it seems like it acts as its own faster frequency / shorter wave length.

@All,

I know why SM likes tubes now.  The Longitudinal resonance demands this.  Offering the Dirac Delta Function impulse to a FET does not work per Gate to Source Capacitance is perfect pathway to Gnd.  Nothing reveals how worthless IRF840 FET's are than this test did.  IRF820 is the better choice.  I could not even see the TEM resonance I had proven before.

@All,

Ward sees the light.  Still praying and cleansing ha ha.  Really.

All that seeks truth comes from GOD.   That does not mean it is STILL GOOD!  Remember that.  If you read the New Testement, just a little, you will find instructions YOU are seeking for your life path.  This toroid study is not so important I now believe.  These New Testement instructions were meant for YOU! 

Ya YOU!  Do not evaluate with haste.  EVERYTHING is not as it seems with GOD.  There is none higher than GOD Almighty, Jesus Christ the Lord Our Savior.  If GOD wants me to study this stuff, GOD will make me understand that.

God Blesses, Jesus Saves!  Remember that.   :)  So does Bruce ha ha  ???

Congratulations Ward, and welcome to the most exciting ride of your life!  Jason and I are very, very happy for you.   ;D

It is indeed life changing and something to be very excited about.  "All things become new.." 
(Psalm 150:6)

I made the same decision to serve the Lord Jesus, just over 25 years ago.  He will never let you down, and remains faithful, even when we are faithless.  Never substitute knowing him, for the religions of men (of which there are many).  Read his Word a bit every day and ask him for guidance.

@ All

I was going to send this as a PM, but I thought perhaps someone reading this could also use a little bit of encouragement.   ;)

Alright, back to firing up the BB coil...Where's Eldarion? .... LOL   ;) :D ;D

Cheers,

Bruce
1.  Lindsay's Stack TPU Posted Picture.  All Wound CCW  Collectors three turns and HORIZONTAL, not vertical.

2.  3 Tube amps, sending three frequency's, each having two signals, one in-phase & one inverted 180 deg, opposing signals in each collector (via control wires). 

3.  Collector is Magnetic Loop Antenna, made of lamp chord wire, wound flat.  Inside loop is antenna, outside loop is for output.  First collector is tuned via tuned tank, to the fundamental.  Second collector is tuned tank to the second harmonic (component).  Third collector is tuned tank to the third harmonic (component)  Frequency is determined by taking the circumference frequency, reducing the size by .88 inches.  Divide this frequency by 1000, and you have your second harmonic.  Divide this by 2 and you have your fundamental.  Multiply that by 3 and you have your third harmonic component.  Tune the collectors to each of these.  Input the fundamental and two modulation frequencies, made to create replicas of the fundamental, second harmonic and the third.

4.  The three frequency's circulating in the collectors, both in phase and inverted, begin to create hundreds of thousands of created frequency's, via intermodulation, that subtract to the fundamental and its harmonics.  This is called "Catalyst".

5.  The three AC PURE sine signals, travel through the amplification stage, Nonlinear, producing the second harmonic and third.  (distortion)

6.  These signals then travel the control coils, are rectified by a full wave bridge, and then sent into the output outer loop as all positive pulsed DC.  This then becomes the output and "collects" the current.

P.S.  The Kicks are harmonic distortion with passive intermodulation.  Can't see it without a spectrum analyzer, normally unless trained to see it on a scope.

I'm here!  ;D

Bruce and Ward, I do appreciate knowing I am among other believers; seems like we are a bit few and far between these days. ;)  Thank you for the encouragement.

Now back to the Boyce system: :D

As Bruce is aware, I have already fixed the timing issue with my controller, to no avail.  I have not been idle, however!

Now I can fire up the magnetic bias very efficiently and to any level I want, thanks to a new switching power regulator that I recently built.  It is extremely voltage-stable, and can handle up to 3 amps at any voltage from 0.6 to the supply voltage--perfect for the magnetic bias coil.

I am in the process of rewiring the coil so that it only has three primaries.  No matter what I do, I cannot bring the pulse rise/fall time to anything less than about 20ns, so my only other option was to increase the electrical length of the primaries.  I do not believe this to be a issue; 6 primaries was a bit of an experiment to begin with, and we really need a larger core for more than 3 primaries to become practical.  (It can be done, but would require $$$$ for custom MOSFET drivers that can switch in under 5ns and source/sink more than 9A of current, not to mention the RF MOSFETs, maybe even GaSFETs, and all the associated PCBs, GHz wiring, etc.)  At least this is my current take on it, time will tell if I am correct.

A quick question: Which side of the primary should I be connecting the MOSFET switches to, the clockwise end or the counterclockwise end (viewed from the top)?  I am thinking the clockwise end should be connected to the MOSFET and the counterclockwise end should be connected to the DC power supply, allowing the pulse's wavefront to travel counterclockwise down the primary, but I am not sure on this.  Since I have it all apart now, I want to connect it back up properly! ;) ::)
