    Hi guys,

    Is it possible to implement the FM TX using PLL concept but no to use just a simple chip?

    What i mean is that could i build the circuit for each block contained in the PLL. Such as N-divider, VCO, LPF, Phase detector.

    PLL's have been in existance since 1932. Those people did not have transistors, so I expect you can do it also.
