Hello
It's possible to build a simple low power (50 - 100mW) vidéo transmitter (with or without audio) ???? but i need to use a 50MHz crystal to have a stabilised frequency.
I don't found anything on web, anybody have an electric diagram ???
thks

 

Why do you want to use 50MHz? This is not an approved transmitter frequency.

 

because I have a 50 MHz crystal, and my TV tuner start at 48MHz

Ok it's not approved frequecy, but I need a very low range (less than 50m), I think only a 1mW output power is sufficient.

I live in africa, and here nobody will be annoyed

 

here http://www.seekic.com/uploadfile/ic-circuit/200961845950513.gif

this is 440 MHz video transmitter use a 55 MHz crystal and 3 stages of oscillator doubler

It's possible to eliminate the three stages of doubler ?

 

pleaaase any one can help me ???
I found many Tx on 50 MHz, but not with crystal oscillator
