[Lowfer] Frequency usage question

[N8OOU]

John, thanks for the captures from your archive. The Wm exciter will 
operate based on a switch selectable R/C oscillator or crystal that is 
pulled by a control voltage.
In trying to understand the circuits, I wondered if the signal would 
drift as it does not have any "environmental control" other than the 
metal case. In my testing I could impart a small frequency change by 
just breathing on the oscillator area.  I may need to change where I 
planned to locate the exciter.
