I did not test it, but it should work.
You can test to see if you are getting VLF in the 200 m radius by using a small VLF loop receiver tuned to the frequency you are transmitting.
Hold the receiver loop horizontal, then walk around inside the 200 meter radius to see how strong the transmitter signal is at different locations.
Best wishes,

tank you very much j-p
no.I'm not interested To use this circuit.The circuit was a argument with wm6.
I need the schematic from the 8038 and vlf.Please give me another vlf transmitter with 8038 with Loop antenna with enough power to send a signal to a radius 200 m
How is the signal propagation in the loop antenna?
Please show me paintings
tank you
