The Broadcast Electronic

TV transmitter requires supplies voltage of 9-15 Volt. However, you can also use a 9v batteries.


This is an important thing to remember for building of the tv ransmitter circuit is that the dimensions of coil size to match the frequency of the desired work. The value of the spindle is making coil as follows:
L1, L2 = 3 Turns, diam. 3mm, 0.5mm wire
L3 = 2 Turns, diam. 3 mm, 0.5 mm wire

Transistor components that are used for a video transmitter is BC548 or you can use another type of transistor BF199. Meanwhile, other passive components used SMD type. For winding coil L1 is 5 Turns 8 mm in diameter and use wire AWG 0.3-0.5 mm.


Once you up the circuit this video transmitter, antenna use as a cable along the 50 cm. To determine the frequency of work, turn the trimmer capacitor 22 pf accordance with the frequency that you want.
