    Hi
    What should be the best or simpliest version of
    one RF transistor as fm oscillator/mixer in fm receiver circuits?

    A best circuit is completely different to a simplest circuit. The best circuit works well but the other one has poor performance.

    well
    simply the best...
    of course there are many ...complex osc/mixers that are not the best
    as we all know...
    so question is the simpliest solution for fm osc/mixer?
    any schematic or link ?

    There is no "best" whatsoever.
    What is best depends on the requirements you have:
    • price
    • complexity
    • size
    • power
    • endurance
    • ...
    These are antagonists. For example: usually low price and hihg power are mutually exclusive. A simple solution may result in poor signal quality. etc. etc.

    Ok
    I was asking for schematic..
    if is not problematic

    Specifically you asked for
    Without telling us what your idea of "best or simplest" is, it is not possible to answer your question.
