I am making a 2 Watt FM transmitter. The transmitter's inductor is somewhat like this :-
The resistor is part of the transmitter circuit. I am little confused with the inductor and not sure how to make it. I have small ferrite toroid. Will it work?
And 0.8mm CuAg wire means 20AWG. If I replace it with #23 or #26 wire, how many turns would be applicable? For L2, would a normal insulated copper wire work? And should it overlap L1 on the ferrite, or co-exist on the ferite beside L1?
I am referring the below circuit:
Any idea, if L1 and L2 can be replaced with a single air-core Copper Coil?
