instead of the inductor used i put a piece of wire and made it into a coil
Note that this circuit is primitive ...
What are you trying to do with this transmitter?The frequency is given by the formula 1 / 2 X pi X sqroot (L X C), but as the circuit has the oscillator as the output stage , its frequency stability will be terrible.You need some kind of crystal oscillator followed by a multiplier to get a stable frequency.
Like 100,000pf for the resonating capacitor? ;')
in fact this frequency in my country is used (can i still be using it and interfere to the station that is using it ?)
Well, it is only about 2000x larger. :'/ What happens if I put mining truck tires on my car? It isn't meaningful any more to ask how fast it can go, because it won't work.Tuning the radio? I meant tuning your receiver around until you hear the signal from the transmitter.We need to know a lot more about the inductor to calculate the inductance. Is that 5mm inner or outer diameter? How long is it? Wire gauge?
Quotein fact this frequency in my country is used (can i still be using it and interfere to the station that is using it ?)Most countries will not allow you to transmit in this band anyway.If you fill in the location information in your profile everyone can see it and give you better advice.In general this is a broadcast band and using any frequency is illegal especially using such an unstable circuit.
First, tell us what you are trying to accomplish.
