Well, color me embarrassed.
I totally missed Adafruit selling a module with the Si5351 chip installed and ready to hook up.
You should be able to put together your own "kit" from an Arduino pro-mini board, the above-mentioned "clock oscillator" board, encoder and OLED display.
He shows the hookup in the PDF.
The file to download into the Arduino is apparently the binary only, and not the source code.
Bummer. Would save me trouble. But I'm thinking Browning Mark 4, Mark 3, etc here.
Kept procrastinating a setup with the AD9851 DDS chips from Chinabay.
But hacking this setup for the old tube radios looks less intimidating.
So far. Ordered a few of the Si5351 boards from Adafruit. Already have some pro-mini board, and the serial interface to program them.
Pretty sure you'll find the whole shopping list at Adafruit. Didn't search for the stuff we already have on hand.
No more excuses.
For now.
