[Milsurplus] Osc Setback: NEVERMIND

[David Stinson]

Well this is what I get for writing stuff before my customary
third pot of morning coffee.    
That's OK; being wrong is one thing I do really well.

I didn't have my test equipment set-up correctly.
The noise and spurs out of the simple Osc booster
are not nearly as bad as all that.
I used the output of  a no-AVC receiver 
(RF gain way down) into a fixed audio load and set
each measurement freq for a 1KC tone.
The fundamental I set at 1.5 V PTP as a reference
for relative-type measurements.
The worst spur is at 3830 KC, reading 60 millivolts PTP.
The next is at 3970, reading about 35 millivolts PTP.
Any other spurs were beneath my noise floor.

I tuned to 3880 KC to look at the rise in noise floor
from the noise output of the oscillator.
Set the noise floor at 50 millivolts.   
Keying the oscillator raised it to 100 millivolts.
Moving further away in frequency reduced it in 
a linear fashion.

I think maybe we can work with this.
