Bliley BG9D 100 kHz (kc) Glass Octal Crystal

Short term stability on a 6C4-based crystal oscillator is pretty good...
the phase noise is going to be lower than some PLL bench oscillators.

Long term stability... it's not very good... it's not good enough to pass
current FCC broadcast standards, even, without a really good oven. On
most of them you can see the frequency jump back and forth as the thermostat
opens and closes....

Proportional control, with modern parts will really help. My lab is
20C+/-3C, so getting 70C+/-1C should be pretty easy. Unfortunately,
that will still be pretty sloppy (about +/-1ppm). Just fine for
boatanchor calibrating and frequency spotting.
