HF (8.2MHz) loop antenna is resonant at 6.3 MHz (lower than required) without any capacitors across terminals. How to re-match it to make it resonant at 8.2MHz?
Antenna is driven by a MOSFET driven by on-off digital pulses - like a switch. Antenna is connected to Drain of MOSFET and there is current-limiting resistor in MOSFET Sink - that's all the circuit.
