Hi Jim, Geri, Wolfgang,
Copied your PSK31 QSO last night from 20.20 till 21.00. I had left the Rx on
137.5 but missed the first part because sigs were 8Hz later.
Jim was solid copy of course, but still the occasional error. I was fascinated
to see how Jim occasionally sent backspace a few times to correct an error and
how this was acted upon by the Rx software. Shame one can't use that to
actually correct transmission errors, hi!
Both Wolfgang and Geri were good copy at times but at times just random
characters. It seems to me this is just the typical failure of another machine
recognition method. The software simply gets out of sync in the presence of
QRM. We can see when it is in sync because of our knowledge of words and the
context of the QSO, but the software doesn't have this ability. When it does
get that smart - look out!
I append below the uncorrected output to give a flavour of reception. If you
are not interested delete this email now.
73, John, G4CNN
Andy running 170W linear at moment. OK eae> ethe coherent signalling - will be interested to see what happens when u get it all goinge e o o
ue I think that is probably ve?eo|e s
p for long DX working on LF, or something similar, just problem of getting
enough stations ready with all the gear. So will sa 73 to Andy if u are off,
and put back to Wolfeagn - DF0WD es Group de M0BMU kn

OK, think Andy now QRT to ee nN on with other buisiness, HI. Well thanks to
Wolf for QSPing Geri 3 esigs to me, I can see Geri on spectrogram trace, but
still quite weak - might come up again, or tu e o ybe condx were better earlier
in evtoning when I had good copy of both ur sigs. Hope your fingers warm up
soon, Wolf!! here it gets too hot in shack with TX es PSU going, have to keep
window open
to eL at a bit of air in - problem other way round fIe me! Well, it has certainly been nice for me to th tout a different mode on LF although I think all other stns tonight have ued PSK31 before on LF... But ier s egood to have some variety. So I will put it back to the DL side - perhaps we can see if Geriee ?pBas come up a bit? DK8KW es DF0WD de M0BMU eÒpbe}e
M0BMU and the group this is DK8kkR 0 W t, Je e0 'F rul
to co a bit more this over ... thank you very much for the QSO and I hope that
we will have someobeetter conditions betweenoPeineom r Yb i he nfcture.
