Hi Graham,

OK, but most people are just transmitting beacon signals! I would not 
even have the time to do a real QSO in QRSS-60 but this is not the 
issue. We are talking about beacon transmissions like WD2XGJ or OE5ODL 
does it each night. RA3YO is transmitting "Y" in DFCW 60. So, if you 
receive 10x "Y" you could receive 1x  "Y" in one night with 10 dB better 
S/N. But the thing is, that this 10 dB S/N can make the difference 
between receiving a weak trace (positive reception) and receiving 
nothing at all! Transmitting "Y" in DFCW-600 takes about 44 minutes 
which is no problem! People can think about that and may choose their 
personal wanted QRSS/DFCW mode :-)

Ask Jim/M0BMU about his reception of my signal on VLF. He keeps the 2nd 
best RX distance at all on VLF! Ask what he would have received if 
choosing QRSS-60 (about 45 mHz FFT). He has taken the time to drive out 
of the noise and got a doubtless positive reception. If i would have 
transmitted QRSS-60, it would have been "lost" time and energy, for him 
and for me!
