Wavefront : 35165.5

[darkspeed]

Wavefront..

Vibration of 1-3 hz

Very slight resistance to moving in free air

The 35k pulse combines to create very low 1-3 HZ wavefront

Signal source : HP Agilent 3325A /001/002  set to  10v PP Square wave   

1k 1/4w resistor between HP output and coil input      << wont work without it

Oscilloscope : BITSCOPE MODEL 325 set to 10:1

Probe : 10:1 Analog Probe ( PRB-01 ) 100mhz set to 10MΩ

35165.5 HZ is the transition point where the wavefront changes direction

35156.0 HZ creates rotation opposite of 35157.0 HZ

Wavefront is 38.6v PP and can be tuned down to 1HZ

Complex intermodulation when the probe is placed on a tank reflector

I know I am loosing a lot of energy in noise at the moment as my short coils are not exactly tuned yet.

There may be some advantage to shift the base frequency up or down to get a wavefront of 6khz rather than 3hz where i am now.

Looking down on it : All coils rotate anti-clockwise ( in NA )

Construction:
standard 11lb magnet wire spool
weigh spool on lab scale
wind one layer of 28 awg 200c magnet wire
weigh spool on lab scale
subtract to get the weight of the wire ( 52g )
spool off 52g of 13 conductor litz wire (twice )
take one length of litz and wind it half way around a high frequency core - the remainder of the length of litz becomes the short coil at the end of the spool ( red wire )
do this again to get an identical coil at the other end of the spool.
place a lcr meter across the open ends of each coil to get the inductance in mh
close each circuit with the appropriate cap to get RF around 35k
double check your RF with a scope and a signal generator
it would be good to put a variable cap in line to tune the coils

In the photo I am driving the long coil and using the short coils to create reflections of the signal in the long coil, this is only for testing.

Ideally you would drive the top short coil which would transmit into the long coil which in turn would transmit into the short coil at the bottom which then recycles the signal and its harmonics through the core and back into the top coil to create a reinforcement - harmonic feedback



And as you get off signal the wavefront starts to break up rapidly like this at 36160.0 HZ

Interesting , you have traction ?

Are you able to show us the coils hook up ,  and lenghts etc?

thanks, Darkspeed

Very cool coil setup. =]

Speed

Its actually quite beautiful!!
And she don't drive to bad either [also beautiful]
