I do not have those. Thread starter mdanh Start date Apr 21, Sarma makes good point, make sure there is no input signal to this stage while measuring frequency should have been obvious.

The schematic is now made using eagle and pdf attached to enable discussion. Once you have enough specs, you can do a “parametric” search on places like Digi-Key, Mouser, etc. Thanks again for the suggestions.

daatasheet I will continue with the entire circuit when I have time to. I seriously do not think there are any connections issues – this is my 3rd attempt, all with same results.

However, although the audio can be heard on the TV with video after some adjustment, there is always a background white noise. Potentiometer Questions Started by norbss Yesterday at Crossing these is a little difficult.

I replaced the trimmer in the FM transmitter with a variable capacitor from a radio that has a plastic handle so that I can tune it without causing disturbance. Thanks for the schematics althought it is mirrored and I need to flip it horizontally to view it.


I enjoy your working around fm audio and am video circuits. For a better experience, please enable JavaScript in your browser before proceeding. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Hi panic mode, thanks for the detail explanation on the circuit and the differences with other circuits. I am currently using a 47uH resistor-like inductor with a 35pF trimmer capacitor.

Is it because I must test it with the main section, or can the audio section work alone to provide a 4. This happens datasueet all the TVs that I have. I tested the circuit by building the audio section alone and using my 50Mhz digital oscilloscope and monitor the on-screen frequency counter.

Any ideas what cause this? I added 22sc2053 of my build front and back on a veroboard. I found the layout diagram to be weird and confusing.

Sure that in the begining they appear hardnut, as you dagasheet things would be to your satisfaction. I spend a lot of hours checking for connection errors on the stripboard. The circuit does not work as expected e.

The waveform at the output is apparently the input audio waveform, with reduced magnitude. Just for the sake of curiosity, is it feasible to build a TV transmitter with audio by using 2 independent transmitters, dxtasheet for video and the other is for FM-audio tuned to the audio channel?

All I get at the output is 0. Thanks for any advice. To participate you need to register. By continuing to use this site, you are consenting to our use of cookies. The FM transmitter audio, however, can be heard clearly with no background noises on my radio. I got the idea from http: Just saying hello Started by MichaelaJoy Yesterday at 6: Also is it correct that the other lead of the trimmer capacitor is connected to ground according to the diagram?

I think I will stick to common transistors 2N and operate at low frequency only. It is random no matter how I adjust the trimmer capacitor. I used a 2N instead.
