[Collins] SSEng DVFOII

[kiyoinc at attglobal.net]

The SSEng DVFOII showed up the other day.

This is a direct digital synthesis device with LCD readout and 
programmable steps and display offset.

The most common application is a stable VFO for a small receiver or 
transmitter.

After a email exchange with a fellow who uses one to generate signals 
for the 1st Mixer of his Drake R-4, I bit the bullet and ordered one, to 
use with my 75S-1.

My goal is to "all-band" the 75S-1 with minimal, hopefully no internal 
modifications.

Theory of operation

I'll be ordering Glen's crystal switch-set.  I still have not figured 
out which one would work best.

I'd move the 75S-1's internal crystals to Glen's switch and use it to 
switch between the crystals and the external "DVFO".  I don't know if I 
need to "modify" anything to replace a crystal with a signal source.

I'm guessing that the oscillator will lock onto the DVFO's signal

The DVFO fits perfectly in the Collins-look, small LMB box.  There's 
about 1/16 of an inch on each side.

It should look just fine sitting on the 75S-1.  Now if it'll just work.
