It looks like Stefan is ATTACKING anyone that does not agree with his point of view.

I find it difficult to envisage using QRS600 when already this past several years faster speeds have proved adequate to cross the Atlantic and beyond.

however

if others favour 600 good luck but I can manage without it.

and don't forget the POP UP CALENDAR and beware of the dreaded QSB during the month long qso !!

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!
