Yes we need to learn how well these signals stack up. We'll
probably need that technique in the toolbox for ULF.

That's a good plan.  Hopefully strong enough to decode each
day individually.

I tried some stacking of days and nights during your epic
828.25 hour carrier at 2970 from June/July.  Soon I hope to
do continue work on that long recording. I have a new scratch
disk to install in my PC which will speed up processing of the
459.85 Gbyte data set (35 days 3 channel flac compressed). Now
it is winter I look forward to spending more time on that.
