The waveform at the output is apparently the input audio waveform, with reduced magnitude. Is there a formula for calculating the output frequency? Once you have enough specs, you can do a “parametric” search on places like Digi-Key, Mouser, etc. This happens on all the TVs that I have.

Sarma makes good point, make sure there is no input signal to this stage while measuring frequency should have been obvious. I tested the circuit by building the audio section alone and using my 50Mhz digital oscilloscope and monitor the on-screen frequency counter.

The FM transmitter audio, however, can be heard clearly with no background noises on my radio. Thanks 2sc20553 the schematics althought it is mirrored and I need to flip it horizontally datasheer view it.

I found the layout diagram to be weird and confusing. The schematic is now made using eagle and pdf attached to enable discussion. Is it because I must test it with the main section, 2sc205 can the audio section work alone to provide a 4. I am currently trying to build the audio section of the circuit see http: I will continue with the entire circuit when I have time to. Thus it is prudent to use combined one. I used a 2N instead.

Welcome to our site! Articles Top Articles Search resources. I am currently using a 47uH resistor-like inductor with a 35pF trimmer capacitor.

I do not have those.

Also is it correct that the other lead of the trimmer capacitor is connected to ground according to the diagram? Can replace the 2SC transistors with the transistors that I have? It is random no matter how I adjust the trimmer capacitor. You must log in or register to reply here.

I think I dahasheet stick to common transistors 2N and operate at low frequency only. Crossing these is a little difficult. It seems strange to me.

Started by fastline Yesterday at 8: Here’s the datasheet on the 2SC, notice the transition frequency isn’t even listed – pdf1. To participate you need to register. Thanks for any advice. However, although the audio can be heard on the Datasheet with video after some adjustment, there is always a background white noise.

Thanks again for the suggestions. I added pictures of my build front and back on a veroboard. I datasbeet the trimmer in the FM transmitter with a variable capacitor from a radio that has a plastic handle so that I can tune datasheet without causing disturbance.

Hi all, Thanks for the tips on getting the equivalent transistors for 2SC I will work on the main section and post back if any problems.
