Fig. 13. — A parameter proportional to electronic tuning plotted vs deviation from 

 optimum drift angle M for various values of loaded Q. For lower values of Q, the fre- 

 quency varies rapidly and almost linearly with M. For high values of Q, the frequency 

 curve is S shaped and frequency varies slowly with A^ for small values of A5.

Fig. 14. — The relative power output vs a parameter proportional to the frequency 

 deviation caused by electronic tuning, for various values of load. For zero loss and zero 

 load, the curve is peaked. For zero loss and ojjtimum load, the curve has its greatest 

 width between half power points. For zero loss and greater than optimum load, the curve 

 is narrow.
