A four day run of the Octo sampling at 48k/sec with PPS from
a neo-m8t.   The PPS jitter is around 30nS most of the time,

 http://abelian.org/vlf/tmp/180225a.png

The Octo sample rate is also staying quite constant too.
The GPS has a poor view of the sky.

The Octo is working well at 48k/sec.

No feedback from the Flatmax Octo forum on the glitches at
96k/sec.  Even if I keep the input level below 1.3V it looks
like the S/N is poor.   As it stands, it's not really usable
at that rate.  My LF rx project is stalled without a 3-channel
96k/sec capture.

Later today I'll put the Octo back to 96k/sec for another play.
