Let me think about the 2570 and 4390 options.  I'd like to check
those frequencies to make sure they're free of interference first.

Can you confirm that the phase of your current 2970 transmission is
the same as the phase you transmitted on Jan 21st 08:00 to 17:00 ?

Currently having fun with the new disc.  It's so much quicker to
analyse signals on this machine, just 20 mins for a 24 hour
spectrum in 11.5uHz and I can run 6 of those at the same time.
