    Hi all
    Is there anyone who can guide me in this project
    I had a problem in this circuit:
    I wanted to know how can I make this circuit, the output frequency of 650 MHz wide
    What can I change the elements to achieve this would

    Hi sata
    welcome to the forums :)

    your question is a bit meaningless. no transmitter, TV or otherwise is 650MHz wide
    do you want it to transmit on the 650MHz freq ?

    That particular TX circuit you have shown looks to be more like a low band VHF TX, particularly when looking at the 2N3904 transistors that are being used.

    to get it to the UHF band it would require a major redesign. Thus it would be easier to find a circuit or existing transmitter to do the job that is designed for the UHF band
