Does anyone know how to make a amplifier/preamplifier for an rf device that runs at 49mhz? i have this old r/c car that i took apart and used the circuit boards to make something else, and it only has maybe a 100 ft range. i want to improve that range as best i can, but i don't have that kind of skill to do it. i just got these old radio tubes, or vacuum tubes, i think, from a 1960's electrics kit, and i know those can be used to improve range. i'm not saying i want to use them in an amplifier but it would be good to know how to use them, like in a ham radio. i just need this to amplify the transmitter signal a lot so i can get about 1000ft or more out of it, but it also needs to be portable, and not huge. can anyone help? thanks
the transmitter runs at 49 mhz with a 9v battery
