The advantages and disadvantages of  using  Ham Transceiver  instead of J.Corum  setup.
https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg536279/#msg536279
Advantages:
1.  one box operation
2. only battery is required to power  the device  or AC.
3. fast automatic tuning
4. visual observation of SWR
5.  if  Ts-B2000 is used   than  it is even more convenient:
a. remote head TM-D700a is  connected with 6ft -12ft cable.
b. radio can be   in convenient position and head can be    next to your  eye  view.
c. when Tesla coil is used than  TS-B2000 can be  at some distance say 54ft and head can be  another 12ft from the  radio

Disadvantages :
1. when  SWR/ VSWR is to  big ( mismatch 1-3  and  more ) you  shouldn't
    use  continuous carrier as you may damage the power  transistor
_{note : front-end transistor term  is reserved to  Rx  not to Tx  (and  that confuses some of  you)}

2. High Standing wave is not friendly environment for  Transceivers_.


recommendation:
use of  Transmatch
http://www.arrl.org/transmatch-antenna-tunercan help lot_{.
note : TS  2000  and TS-b2000  both have automatic antenna  tuner  however  additional   transmatch/ antenna tunner is  recommended.}


1. switch Tx to CW.
2. connect  Key
or
3. automatic  keyer
4. don't allow  continuous long dashes  better use dots.

reasoning:
1.Tx  has approximately  the  same amount of  time to rest between  dots  or  short   dashes (as is used to transmit.)
2. The power transistor  cool-down is very effective between  signals.

Advantages
of  use J Corum configuration:

commercial amplifiers are very tough.
-strong enough to withstand adverse conditions or rough or careless handling.
- most of  them  have overload circuitry.
- lowering  voltage from signal generator you can  regulate output power from PA.
-you can deliver  to PA  sinusoidal signal or any other  waveform  of your choice.



Disadvantages
of  use J Corum configuration:

-when  you  blow your amplifier - you can say goodby to  it.
and you will be  hunting for another one for quite a good time.

<sub>Note:
-this equipment is 3 times  more  expensive than Kenwood TS-2000
  but ham  equipment is often very  cheap and  easy  to find.
  at best on hamfest.

- you can use any of other  transceivers  e.g Yesu.
   there is large  amount of 100W output   Mobile  transceivers with remote head,.

Note:
Use of unmodulated  CW  (A1   European standard known as A1)   is   your sinusoidal signal.
Use of     modulated  CW  (A2   European standard known as A2) with usually 800 Hz- 1kHz  signal   is   your "square signal."equivalent  if keyed.

The difference  is that that in 
A2 - you are dealing here with modulated carrier at length of dots or  dashes mechanically activated but electronically spaced.
However for effect of J. Corum there is no difference.
Preferred is A1</sub>

Configuration for test:
1 take  J.Corum equipment  and connect it as shown here:
https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg536161/#msg536161

or

1a.take Kenwood TS-b2000 or any other  e.g Yesu and  you don't need anything  else

1b. make  sure that frequency  of Tx or Trasceiver is  52MHz.
----------------------------------------------------------------------------------------------------------

2. connect surface wave probe  to  output of   your Tx or amplifier.
2a. if using TS-b2000  you have  additional   transmatch it is your big benefit.
2b.connect your  transmatch (antenna  tuner) between   surface wave probe and your TS-b2000

Note:
Your surface wave probe is  your Tesla coil.The load of your  Tx or Amplifier  or  your transmatch  is  your primary winding of Tesla  coil The secondary of your Tesla coil must be grounded

The parameters of  Tesla coil  for 2200m  are given here.
https://youtu.be/zE4GjB1cWLQ?t=367

use 1.8MHz and  remember that it is 1600m and not 2200m
as indicated on the picture .
is  easy to re-tune 
The  lower the  frequency the   more winds is required.
the  higher the  frequency the  less winds is required

At minimum of 54ft you need to have another Tesla coil acting  as a  receiver.
the distance  can be greater  but not smaller than that

<sub>]top capacitor must!!! have means of  being adjusted in elevation measured from the ground!!
Structure  of  the mast , must be made   from dielectric e.g PCV sliding telescoping   UP/DOWN

Another means of  height  change of  Top  Capacitor is to hung it on   a  balloon  or between  to  masts.  used  to  elevate the Top Capacitor.
The rope used to lift the Top Capacitor UP    can   not be made  from  wire or "dielectric".  it must be natural    string or  thin  rope.</sub>

Top capacitor must  be quite large  at best.
to  prevent  sparks.
It can look like Doughnut  .
The minimum distance of Top Capacitor from the  ground  is 4x its diameter.

Wesley

[stivep]

Adjustment of  distance from  ground of Top Capacitor is  the  most important
factor of  launching Zenneck Surface wave  .

AFTER SUCCESSFUL test  using   power  transfer  in  the  interface in form  of  Zenneck  Surface wave
the experimenter is ready to step 2
-extracting energy (FE) from Schumann  waveguide.
