There are no false decodes with CW fast or slow.
What you hear or see is genuine.
Digital mode results can be suspect
I recently got a digital report but I was not TX at the time

Hi Stefan,
 
beyond the technical aspect that is certainly is the most important thing, there are people like me
who operated in the microwave bands and especially EME that, sometimes hunted a new one for months
before being able to make the qso that, certainly does not scare me a few hours of calling...
Technology has made giant steps and, systems like WSPR  for the study of the propagation,
bring us to knowledge phenomena that we would not have discovered otherwise but, the charm of an
old CW two way QSO is unsurpassed in my opinion.
Surely it was an exceptional condition that I do not think happen again many times during a year but,
the perseverance finally always pays.

Hi Fausto,

Normal CW would have been possible last night! There were 90 decodes by FR5ZX last night. The best reports from last night are:

You know, a few weeks back i've tested the readability of a signal at -6 dB and -16 dB. -6 dB was fine for a normal speed (100 Bpm) CW QSO. -16 dB was barely audible, not fine for a QSO, maybe a call can be copied when repeated a few times. So i think that -12 dB should be fine for a QSO at 60 Bpm and some concentration... But it was just a short moment within 4 hours. Not sure if someone want to call CQ for such a long time to make a "599tu" QSO then :-)

73, Stefan

PS: Could someone provide more statistical overview of last nights results?

Hi Stefan,
 
-14 dB !!!
Virtually with 10 dB extra power you would get an audible CW signal...at 9000 Km WOW.
