But where's the non linearity for the mixing action?.
** LOL !!
Never heard of " beats " ??
Never tuned a guitar ?
What a macaroon !!!
Way I was reading it is that the reflected energy is increasing/decreasing
the radiation resistance of the aerial ...
** Nonsense.
You simply invented that notion.
So yes, constant frequency (a little pulling close on target) and R.F.
output voltage but variable L.F. anode current, as the level-control servo
loop struggles to force a constant oscillator output.
** Servo loop ?
You on drugs ??
**** off, troll.
