Thanks for that Graham.

I'm just trying to see how far short we are of an opera decode.

I just got another 0.84 dB S/N improvement by shifting the loop
a little further from the prevailing noise, and by compensating
for the slight elliptical polarisation of the signal.

Markus reported:

> 2014-03-07 06:51:53 ... -48.9dBOp 100% 19.4dB

so I guess that would now be -48.1dBOp.

But still 2 or 3dB short I think?
