R6 is the base bias resistor for the transistor, used to bias the transistor at a suitable point. C3 is to decouple the base at RF frequencies (so it's operating in common base as an RF oscillator), but to allow audio frequencies to pass - it's value isn't at all critical, the higher the value the more it will reduce the higher audio frequencies.mstechca said:The funny thing is that 99% of the circuits I see on the internet do not include an equation that determines all their features.
All the manuals say that the inductor and capacitor in parallel change the frequency. but to me, that is of the least importance. My question is why is the value of C3 0.01uF and the value of R6 10K?
I seem to think that these values make up an equation for something else. I'm not sure if they make the equation for bandwidth or what? but if people must use specified values all the time, then whats the point of experimenting when the specified values do not work? Get my point?
I think the low power station has at least a few thousand watts. It is a real radio station that covers the largest city in my country.panic mode said:that other low power station must be 2watt transmitter (fmtransmitter[2watt].gif) from top of this page
