What is the substitute of BFY90, I think any high ft transistor will do.
Please detail L1, L2, L3 windings, I am about to build this project!
It is almost impossible to construct this inductors. Please give SWG for wire.

Thanks

it's really nice..but is this not compicated to do..

Construction of Inductors and tuning it to a channel for maximum efficiency is difficult. Otherwise it looks simple. To make a successful model more description is necessary.

TV Transmitter is complicated system, many people fail to make it because the wrong to choose amplifier type to boost the RF. You must using very linear amplifier because the amplifier will process Audio and Video in the same time and it have very wideband (about 8Mhz). I prefer you to use MMIC amplifier that have wideband, eg BG2709, UPC1678GV

Mansoor Ahmed,

if you need a mono receiver try TDA7000 IC

audioguru · 25th October 2009, 04:04 PM

The TDA7000 is not made anymore.
It was an extremely poor quality FM radio.

Hi there,

I build a video-audio transmitter.
I use the schematic from Henry from Indonesia and I must say "it works fine"!
Frequency 470 - 860 Mhz, 15 mW.
Tell me/us about your tv transmitter project.
I can sent you the schematic and the HEX code for the PIC, let me now![
