Look at all the other higher power transmitter circuits. They use a tuned LC circuit to match the output impedance to the antenna impedance. Mine uses only a simple coupling capacitor.
They use much more average current than a little 2n3904 can handle. The maximum allowed current of a 2N3904 is 200mA and it works poorly above 50mA.
Oh then if i add a couple of trimmers to the output of your Tx (like others') to match impedance between Tx and antenn, Can I get more power or range?
