Recently someone posted to the effect that in a tuned plate tuned grid
oscillator, if the anode resonant frequency was lower than the grid
resonant frequency, the tube would not oscillate. Did I catch that
right? And does this apply in a grounded grid oscillator as well as a
grounded cathode one?

So, in the context of the dreaded grounded grid VHF
para-you-know-what, is it really that simple? Keep the cathode-grid
resonance higher in frequency than the anode-grid resonance and it
won't oscillate?
