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 :-)

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.
