Thanks for the suggestions. I ordered the Ramsey kit as a way to have
something to play with for now.
Next step is to lash together either a PLL-VCO combo or DDS to
control the tuning from a cheapo processor (e.g. PIC). Any
suggested starting points for this would be much appreciated (for
example "National LMX2xxx plus Minicircuits xx" or "forget that,
AD DDS is better because.......")....8-).
The guts of the Ramsey widget consists of an SA602 and an
MC1350 (single conversion with 10.7 Mhz IF). Potential ways to
"improve" upon this???
Thanks again.

quantities.
