I've got a "middle of the road" size junk box collection. Probably over 100 
crystals including old FT-243s, CB crystals, crystals out of stuff that's 
broke over the years, etc..

If I remember right, I had three or four that would divide into the right 
range using "divide-by-2" multiples like you get out of the 4060. I did look 
for crystals that were also 185.3 kHz apart and didn't find a single set of 
them.

If it's got to be 185.3 kHz, then I think the simplest thing is to just order 
on the of programmed oscillators and run with it (maybe with a divide by 10 
or something after it). I also dug through a lot of surplus sites and parts 
houses catalogs. I didn't find anything widely available that divided into 
185.3 kHz or that had a difference of 185.3 kHz.

I'd agree. And I just don't see how to do simple unless the watering hole is 
moved. Like I mentioned, I'll be using the DSS soon, so it's a moot point for 
me. But I think getting to a frequency where you have a fair number of people 
listening to you is important for anyone starting out and a "barrier to 
entry" for anyone wanting to KISS.

If someone has an easy, off the shelf way (other than programmed oscillators) 
to get to 185.3 kHz, I'd love to hear it--that would free up the DSS for 
other projects.
