Hi Mike,

All right. After the currently= running experiment i'll run some carrier
or maybe DFCW-60000. I'll ann= ounce it a few days before.
Make sure a 47 uHz window is running to that= time, maybe two
Spectrograms, one showing 8270 Hz, the other one showi= ng ALPHA F1,
11904.7619 Hz.
Locking to GBZ or GQD or 1 PPS is a requ= irement! Maybe Eddie can help
you if necessary.
