Performed high voltage DC test of 200 VDC. zero amps read. test

Next combination.

These tests will not produce amperage as there is a break in the flux line, one with the power supply and two with the amp meter.

Hello everyone,
Been juggling too much life lately and have to take a break.
I got to wondering about injecting 2 mixed frequencies into a single Tesla coil primary then splitting them into tuned tanks of the dual secondaries comprised of twin lead antenna wire. Its a Tesla coil with an air core.
I have seen very complicated radio circuits that deal with multiple frequencies but i am trying to keep it simple.
The drawing shows how simplistic I want this to be. I tried modelling in Falstad simulator but there seems to be inherent misgivings about its operation.
If a single primary is not possible then I added the dual primary design.I start with a secondary that is already built. It is 5" diameter and an inductance of 18uh and 53 turns. There is an inherent capacitance of 290pf. The primary is 16 turns of a single side of lamp wire.
Thanks in advance.

Interesting thought!

Will your secondary windings differ to accommodate the two
separate frequencies?  Tuning Capacitors?

Will the two frequencies be fairly close or possibly harmonics?

Are you aiming for the typical High Voltage Tesla Coil output?

I believe it will work.  The concept certainly works with Audio
Transformers.  Multiple frequencies that can be individually
tuned and isolated.

And it works with Receiving Antennae.  Well, sort of.  The Antenna
doesn't resonate at all frequencies but they can easily be
individually tuned and isolated.  Aboard ship we had a single antenna
feeding numerous separate receivers operating at different frequencies.

Some of our Transmitting Antennae were "broadband" and could be used
with several different frequencies at once.

Yes, it should work!

In regards to the two secondaries there will be an offset.
At the start this is a bailywick since I only have the secondary specifications: Wire length, wind diameter, and 18uh of L. I can easily change the primary length.
It is also on a slider sheath to enable moving along the secondary to change the ratio between voltage and current.
Simplicity is in my crawl because I believe this build can be kept looking just like something Tesla would have built. Windings, caps, coils, resistors and diodes and nothing else.
The thing is that when achieved this can be driven by two oscillators or a stungun/broadband.
Once this transmission side is done then that supplies the parameters for receivers.
