Once you have enough specs, you can do a “parametric” search on places like Digi-Key, Mouser, etc. I xatasheet the circuit by building the audio section alone and using my 50Mhz digital oscilloscope and monitor the on-screen frequency counter.

I am currently trying to build the audio section of the circuit see http: Thanks for any advice. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at You must log in or register to reply here. Just saying hello Started by MichaelaJoy Yesterday at 6: Thanks for the schematics althought it is mirrored and Datazheet need to flip it horizontally to view it. Sure that in the begining they appear hardnut, as you progress things would be to your satisfaction.

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 datasheeet been obvious.

The FM transmitter audio, however, can be heard clearly with no background noises on my radio. Here’s a page of tips that might be helpful – http: Media New media New comments Search media. I added pictures of my build front and back on a veroboard. I finally made it work by: I will continue with the entire circuit when I have time to. The circuit does not work as expected e. Here’s the datasheet on the 2SC, notice the transition frequency isn’t even listed – pdf1.


I used a 2N instead. I got the idea from http: I am currently using a 47uH resistor-like inductor with a 35pF trimmer capacitor.

Also is it correct that the other lead of the trimmer capacitor is connected to ground according to the diagram? The waveform at the output is apparently the input audio waveform, with reduced magnitude. Hi panic mode, thanks for the detail explanation on the circuit and the differences with other circuits.

Is it because I must test it with the main section, or can the audio section work alone to provide a 4.

Forums New posts Dstasheet forums. However, although the audio can be heard on the TV with video after some adjustment, there is always a background white noise. The 2SC has a transition frequency over 1GHz, the 2N is a fraction of that – it just isn’t fast enough. I seriously do not think there are any connections issues – this is my 3rd attempt, all with same results.

Hi all, Thanks for the tips on getting the equivalent transistors for 2SC Started by fastline Yesterday at 8: Thus it is prudent to use combined one. The schematic is now made using eagle and pdf attached to enable discussion.


Any ideas what cause this? I spend a lot of hours checking for connection errors on the stripboard.

I found the layout diagram to be weird and confusing. Is there a formula for calculating the output frequency? Hi, I am trying to build a simple TV transmitter following the instructions at http: Electro Tech is an online community with overmembers dataasheet enjoy talking about and building electronic circuits, projects and gadgets. Potentiometer Questions Started by norbss Yesterday at It was very difficult to get the FM transmitter to tune into exactly 5. It is random no matter how I adjust the trimmer capacitor.

Crossing these is a little difficult.

I enjoy your working around fm audio and am video circuits. 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 FM-audio tuned to the audio channel?

This happens on all the TVs that I have. With a schematics, it’s better. Articles Top Articles Search resources. Welcome to our site!
