I'm looking at the 30 minute carrier and there's
obviously a problem

The main peak is off frequency and it's jumping
around a lot.   Could be a problem with my timing
system.  It's reporting a max error of around 40nS
which is only a degree or two.  I'll go check what
MSF 60kHz and BBC 198 kHz look like.

Best decode of the 18:00 messages was with timing
offset +60 mS which gave Eb/N0 +2.1dB which is about
5dB worse than it should be given the carrier strength.
