    Looking for some help to build an RF Modulator schematic from 1985 I found online :)

    Hey all, I am looking for some help to build an RF Modulator schematic from 1985. I was searching for a way to wirelessly transmit a UHF/VHF TV signal to an old portable TV I have and found a schematic on a website called Petlibrary (https://petlibrary.tripod.com/rfmod.htm). My idea was to use...

    VHF oscillator circuit w/ large frequency range and change according to capacitance value

    Hello, It's my first post. I'm new in electronics fields. I'm french and my english is not very good, excuse me. I want to make a VHF oscillator(~ 30 MHz) that his frequency can change with the value of the capacitance. I found in an another post the RF2506 which seems to works but it's...
