what about H-Brigde or a Relay (could I amplifie a signal with it?) (I have custom made H Bridge with chips and you can connect a power suply to it and drive motors but I don't know if they can amplifie a signal with it (and there is another problem that I can only transmitt in European FM Band with Raspberry Pi (I would like to transmitt on 76 Mhz (because Japanese FM Band is enpty here in Slovenia)
