Its 300mW including all the harmonics (btw most power meters read a lot higher if harmonics are present). You might....might have 150 to 200mw of real power

I made it with a 2n2222, had to change the 10k resistor to a potentiometer and fine tune the resistance to around 6,5k to tune the circuit, i also used a thin coaxial cable to connect the transmitter and amplifier together because i found that the amplifier doesn't quite turn with the very weak output of the transmitter with a straight piece of wire because it radiates most of the output to the air. The amplifier works but doesnt amplify up to 500mw, maybe 200, and the transistor gets hot, not to the point where it will burn out but hot, around 75C

не надо палить накал, он не должен светиться. там не нужно высокое напряжение и ток ещё должен быть переменным, у синусоиды переменного тока напряжение в полуфазе, в пике, будет в два раза меньше чем напряжение постоянного тока

As it is, it is not working. I think I will put a driver with the ir2153 that drives 2 mosfets after finding its resonance frequency, I have to achieve it. Why is the coil so far from the ferrite? Are there losses in this? Excuse my English, I'm using Google Translate.
