So... if cmos/4000 and not HCmos... you know it doesn't go high in frequency...
The rx can be FM range... no problem running around 100Mhz... but I dubt middle stage is some FM thing. 
BTW Esteban wrote "RF" not "FM" this time.
As always... he posts stamp sized pictures... and people start making wild guesses! 
Kind regards,
