The input goes to the most letft 470nF capacitor. I got it stabilised as much as i can, but the output still wobbles with 500-600mV or so. The output power is around 5W which means quite the radius. On open fields you can easily reach 5-10km or radius. This is somewhat illegal so be cautious. Add screen to the first stage if you build it!!! For the transistors, well, I'm not sure. Probably any newer kind will do, but I'd stay away from the BCxxx series, they have large in/out capacitance. Use the BFxxx series for the first stages and find something powerful for the final stage
