Below is an FM transmitter circuit I found on the web that I would like to build from scratch.
How I would calculate the carirer signal frequency so that I know where to tune my FM radio?
If I want this to transmit my own...
The problem statement, all variables and given/known data.
I am just trying to understand this cicuit a little better. Especially
the right half, I know that the left half is just acting as an amplifier
but I'm not sure how the right half works. Also how is the frequency
being modulated here?
The attempt at a solution.
I know that C5 and L2 are used to calculate the carrier frequency, but I
am very unfamiliar with this type of set up for...

FOUR-STAGE FM TRANSMITTER
PRADEE G.
This
FM transmitter circuit uses four radio frequency stages: a VHF
oscillator built around transistor BF494 (T1), a preamplifier built
around transistor BF200 (T2), a driver built around transistor 2N2219
(T3) and a power amplifier built around transistor 2N3866 (T4). A
condenser microphone is connected at the input of the oscillator. Working
of the circuit is simple. When you speak near the...
