hello, i'm relatively new to ham radio and had a few technical
questions i was hoping to throw out...anyone that can answer these
would be very helpful!

1. i've seen transmitter schematics that were simple, and others that
were complex. as a general rule of thumb, are the more complex ones
trying to compensate for frequency drift, or maybe eliminate higher
harmonics? how efficient and/or stable are the simple transmitter
schematics?

2. other than frequency range, what characteristics are you concerned
about when trying to match a transmitter to an amp?

3. without an amp, couldn't you still run the signal to an antenna and
it would be a weak transmitter? all the amp does is increase the
voltage and current supplied to the antenna, correct?

4. for an FM transmitter, does the modulation occur to oscillator
directly, or is the oscillator's signal modulated after "leaving" the
oscillator? i guess what i'm asking is whether or not there is an input
to the oscillator, or is it just an "output only" frequency generator?


thanks!
