Hi ma330,
There are many easy vlf transmitters posted in this forum including a transmitter with 8038.
If you want to use this circuit that you posted above to transmit in a 200 meter radius, then
you can use the circuit below.
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,
