just a test setup to see how much power could be coaxed out of a tuned FERRITE ROD TRANSMiT ANTENNA resonant at 50Khz using a CAP-DISCHARGE circuit dumping about .6 joules per pulse into a 15 TURN primary of a FERRiTE ROD HV PULSE TRANSFORMER made from material 43 ferrite CABLE COREs(2ndary has about 400 turns) to key the CAP-DISCHARGE circuit, a CW KEYER's RIG KEYING OUTPUT goes to(keys) a REED RELAY - that connects the 12 volt power pack to the cap-discharge circuit board the pulse per second can be adjusted by a resistor in series with the POS lead to the CAP-DISCHARGE circuit board
