[600MRG] Crystals: Where can I get them?

[Murray Greenman]

Phil,

The solutions offered so far will certainly be the simplest. By why not 
step forward a generation or two and use a synthesiser?

You could build your own, but one of the simplest, designed specifically 
as a 'crystal replacement' is the Progrock, by QRP Labs:

     https://www.qrp-labs.com/progrock.html

It can be pre-programmed (without a computer) to provide three 
independent outputs between 3.5 kHz and 300 MHz.
