The carrier is still running but will stop at 20 UTC this evening.

Mike, how does your result look now?

Paul, thanks for the nice peak plot!

Thanks, Stefan. I will set a receiver up today. I always lock SpecLab to a utility station, but it is a good suggestion to display an Alpha as a check that all is working.

Hi Mike,

All right. After the currently running experiment i'll run some carrier
or maybe DFCW-60000. I'll announce 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 showing ALPHA F1,
11904.7619 Hz.
Locking to GBZ or GQD or 1 PPS is a requirement! Maybe Eddie can help
you if necessary.
