Hi Chris, what sort of 10 MHz OCXO do you have? The
little canned industrial types (eg. http://www.kvg-gmbh.de/10.0.html?&L=3 )
will stay within about a couple of ppb
over hours, translating to some 10
microHz at VLF.

The stability of "within a few mHz" could be a problem for those of us
using extremely narrow Spectrum Lab settings to dig your signal out if the noise
Chris. This is where absolute locking to a GPS source is so valuable as one can
screw the bandwidth right down. A few mHz could mean the carrier drifts and is
not detected. Still, I'll be looking!
