I'm working on a project that requires a switched 14 Mhz oscillator.
I am currently using a 14 Mhz crystal, a 1M feedback resistor and a
couple of capacitors on a 74HC00. My problem is that the oscillator
will occasionally either not start or oscillate at a higher harmonic.
When it does work the output is also pretty feeble so I know I'm doing
something wrong.

I would prefer not using a commercial canned oscillator because this
project is pretty cost sensitive. Anyone have any suggestions on what
I should be doing?

Even though I read this group often please email any responses as I will
be out of town for a while and most likely miss any posts because of the
short expiry time on this machine.
