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
Apparently a on line data base is not a big job , for someone who
is in that line .. however as yet that someone has yet to be
found :(
G..

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!

- 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 has commented , the number of stations active on 136
tx/rx is definitely on the increase, where as the PSK map
used to show the odd red spot , now its quite packed !

Interesting , is Op visible at -40 dB ? ,
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
resolving weak signals.
For beacon and propagation tests Opera reports are so much more
convenient than taking snapshots of images of a QRSS grabber screen.
For a QSO, QRSS/DFCW may well be more useful, but the path conditions
can be more easily determined using Opera. It is "horses for
courses".
