[Central-Electronics] CE-20 frequency stability

[k7fm]

Hi Cal:

A stable vfo is fine - but there are a number of things you must consider:

1.  The output level must be sufficient for the 10A.  Often that requires a 
buffer amplifier.

2.  The vfo must have output that covers the full range needed by the CE (up 
to 38 MHz for 10 meters).

3.  This still does not solve the drift of the 9 MHz carrier oscillator.

I use a solid state home brew vfo built into an old BC-221 frequency meter, 
that has a double balanced mixer and switched oscillators to get me to the 
desired frequency.  The 9 MHz oscillator can be stabilized with work.
