My 2N3904 output transistor has a very simple circuit that has low output power because it does not properly match the fairly high impedance of the transistor to the low impedance of a coax cable and antenna.
-If so, why don't you upgrade your transmitter with perfect match?
-Varactor diode and Trimmer both has a same function on tank circuit. If a tank circuit designed with varactor diode, can we replace this diode with Trimmer? Why they use varactor diode instead of trimmer?
