Mal, At the end of the day its down to a contest of who can code the better DSP engine as with no DSP engine , there can not be any pixels' to join up , be that joined in logic or analogue using the
Interesting , is Op visible at -40 dB ? , But yes , it was possible to re hash a message if the ltrs/figs shift had been missed , but the signal levels where many dB's higher and once the change to m
Yes only go's to show , One Guy's ''Pixel'' is another's ''Nibble'' - have to keep in mid, Op is a one-pass data mode , the decode over heads are significant compared to 'carrier detection' - But as
Stefan es Co It is often the case when Data modes cannot be decoded they are visible on the waterfall display. It is also a fact that RTTY can easily be visually read on a waterfall display when it d
Yes Graham fair logic, but with data modes it is ALL or NOTHING whereas with a one state mode like QRSS there are alwas some characters visible and the message just needs a bit of infill for an ID In
Stefan, Unfortunately as of yet , there is no central data server and as observed, the odd spot manages to escape the system , akin to a ad-hoc wireless network ... local records are valid of course
Oh yes! I have done some tests with TF3HZ's grabber and I can see my Op32 on a QRSS screen when he was decoding at very low levels. However, there is not much in it and Opera is very impressive in re
Hm, somehow my initial question and observation was completely ignored... I also remember that W1TAG reported about 2 decodes in one night while i only saw one! 73, Stefan/DK7FC Am 27.08.2012 20:11,
