Hi Paul,

Thanks for the efforts.
Let's just try again, no problem. All the VLF stuff is quite on the limit, 6.47 kHz anyway! Maybe i'll try again with 70 characters first, that's between 40 and 100, and we already managed 40 chars without problems...

73, Stefan

A good choice of settings.  Given the S/N from the recent
daytime messages, it should come in at about +0.5 dB so
about a dB to spare.

Sorry, no success with this one.  Probably a little too much
of the transmission was missing.  It must have been close so
I tried several runs of the decoder with a range of blanker
settings and beam headings.
