27mhz transmitter, can you help? Why there is no wave frequency? What is wrong? Newbies

Many things to tune. Componente values and simulator setup.

Hi hurz, i have mod it. But seems the wave produce is not stable, how to trim the sin wave to be stable?

I would try to amplify the sine wave first then smoothen the ripples. Try capacitors, small inductors, or adjust the components

My tip, make a different circuit and THEN see your results. Since this one just shows the 27MHz as noise and its hard to change.

I think the cap values should be way higher

@sshsslfun expect 27000000Hz while @methamafoz expect 0.027Hz. @sharief5663, were do you want to go?
