[Milsurplus] Crystal Oscillators

[Ian Wilson]

Microchip's PIC processors give amazing bang for the buck and the
programming
hardware is very cheap. You can program them either in-circuit or use
sockets for
the CPU and the programmer. There used to be cheap AD9851 modules on eBay,
these days might have to look at the AD9833 or Si5351a.

I haven't looked for specific projects but I'm sure they are out there.
(Many of them
are probably Arduino, etc; I just prefer PICs because I've used them for
years and
I'm very cheap :) ).

No connection, etc.
