[Boatanchors] Programmable Osc Setback

[David Stinson]

OK, you fellas can "I told ya so."   I won't complain.
On the receiver side, the tiny output of the programmable
oscillators work fine and I hear no problem with 
increased noise floor.

Not so on the transmit side, were the osc needs
considerable "boost" to drive the 6L6 grid.
My attempt to keep the TX Xtal-replacement circuit 
ultra-simple just isn't up to the job.  
The output is noisy and has unacceptable spurs.
Not about to give up on it- I have high hopes it
can be made to work in the BC-375.

A reminder of the over-simple circuit as it is now:

And the goal: use several of these oscillators 
on a satellite board to replace very expensive crystals
(aside:  Bry's crystals work well in many circuits
including the RX side of this rig, but do not oscillate
in this transmitter circuit).

There's a couple of ways we might go from here.
The input impedance of the MOSFET gate is quite high,
so a Hi-Q tuned circuit between the OSC and Gate
might bring the nastys down to something workable.
Might also turn the FET into a oscillator itself, so a 
tuned buffer as has been suggested might be in order.
Can you neutralize a MOSFET?
Operating the MOSFET linear might also help.

Ideas?
