   ** Shame about the other ones, the vast majority of low cost bench generators   
   are simple analogue oscillators that need calibration.

   ** Simple means exist to check AM and FM modulation using the matching   
   receivers or a radio scanner while spurious signals from a 20 to 50mW   
   transmitter are insignificant to the point of being unheard off in practice.   
      
   Arguing from half baked theory is your only forte - right ?

   ** The term "period counter" means the same thing.   
      
   Try reading someone's post carefully before embarking an a campaign of   
   completely irrelevant criticism - fuckhead.   
      
   Cos you are about one tenth as smart as you imagine.
