TV TRANSMITTER AND PAL VIDEO MODULATION SCHEMATIC DIAGRAM
The following is a series of simple TV transmitter using negative using sound modulation and PAL video modulation. This is suitable for countries using TV systems B and G.
Inductor L1 can be made by wire email (24SWG) 4 convolution with 6mm diameter and T1 can be used with a radio frequency transformer internal capacitor. (Can be found on the old transistor radios).
