Dear LF,

WSPR offers new dx records for all LF stations, sure. With QRSS/DFCW it is= the same, compared to CW. Perhaps some stns will successfully do TA QSOs= nw in wspr, congrats!

What will happen if in 2 years the next software will be available with ev= en much better error correction and so on? What, if this software is so go= od that a QSO to VK will be possible?

I mean, does such a software not relativate the value or the personal mean= ing of a QSO? If you reach 5000km with a almost perfect software that does= record and publish everything automatically, is the QSO then done by you= due to your knowledge and your motivation to built up a good station and= the time you (and the QSO partner) spent to get that contact? Or is it do= ne by the software? Is the feeling about a confirmed two way contact the= same in than in CW?

If anyone can run a beacon with 10W TX power into a dipole for 40m and WSP= R accumulates all contacts over time, then it is just a question of time= to get a time/moment of optimal propagation on lf and so you just have to= look if the ODX increased and if not, just wait some days longer...

Is that the same feeling than after a difficult but successful CW contact?= Really?

If we tend to say "WSPR is 5dB better than QRSS, so why are we still= doing QRSS or even CW???", then we neglect this difference that appe= ars to some of us.

For me, personally, WSPR seems to be interesting but not really a choice= since a amateur radio QSO has something to do with a signal that has to= be catched out of a noise by a human, not by a computer. I want to listen= (or at least watch) to a signal that is followed by a human to the same= time and want to get a personal information (not such as 599tu). Anything= else is just in the region of a test that gets boring if the ODX does not= increase any more and fast enough. And all the work will be relativated= when the next, of course better, version comes out...

In my opinion, the more we let the pc do the work, the more we are apart= to the human/ each other and the faster it gets boring.

Stefan/DK7FC
