Hello all,
I have a few questions about radio transmitters (not looking into receivers yet!)
How can you generate a high frequency signal using a DC power source (batteries)?
How is this signal generally amplified for small-scale transmitters, such as walkie-talkies? Is it using BJT's? Would the signal just be fed straight to the base?
How is this amplified signal attached to the antenna?
Links to simple schematics would be great, or partial pieces of information (such as how a waveform is generated using a DC source).
Thanks all!
