Jugis Started by fastline Yesterday at 8: I enjoy your working around fm audio and am video circuits. I got the idea from http: I will continue with the entire circuit when I have time to. I used a 2N instead. I am currently trying to build the audio section of the circuit see http: Thanks again for the suggestions. Any ideas what cause this?

I added pictures of my build front and back on a veroboard. Click here to register now. Hi panic mode, thanks for the detail explanation on the circuit and the differences with other circuits. You must log in or register to reply here.
I tested the circuit by building the audio section alone and using my 50Mhz digital oscilloscope and monitor the on-screen frequency counter. I think I will stick to common transistors 2N and operate at low frequency only. Sarma makes good datzsheet, make sure there is no input signal to this stage while measuring frequency should have been obvious.
Thanks for any advice. 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.

However, although the audio can be heard on the TV with video after some adjustment, there is always a background white noise.
Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Ddatasheet spend a lot of hours checking for ratasheet errors on the stripboard. Crossing these is a little difficult. Potentiometer Questions Started by norbss Yesterday at Just saying hello Started by MichaelaJoy Yesterday at 6: I am currently trying to build the audio section of the circuit see http: I will work on the main section and post back if any problems. Just for the sake of curiosity, is it feasible to build a TV transmitter with audio by using 2 independent transmitters, one for video and the other is for Datasheer tuned to the audio channel?
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. The circuit does not work as expected e. It seems strange to me. I do not have those. Thanks again for the suggestions. It was very difficult to get the FM transmitter to tune into exactly 5. I will continue with the entire circuit when Satasheet have time to.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.
