Hi Graham,
OK, but most people are just transmitting=20 beacon signals! I would not even have the time to do a real QSO in QRSS-= 60 but=20 this is not the issue. We are talking about beacon transmissions like WD= 2XGJ=20 or OE5ODL does it each night. RA3YO is transmitting "Y" in DFC= W 60. So, if you=20 receive 10x "Y" you could receive 1x=A0 "Y" in one= night with 10 dB better=20 S/N. But the thing is, that this 10 dB S/N can make the difference betwe= en=20 receiving a weak trace (positive reception) and receiving nothing at all= !=20 Transmitting "Y" in DFCW-600 takes about 44 minutes which is= no problem!=20 People can think about that and may choose their personal wanted QRSS/DF= CW=20 mode :-)

Ask Jim/M0BMU about his reception of my signal on VLF.= He=20 keeps the 2nd best RX distance at all on VLF! Ask what he would have rec= eived=20 if choosing QRSS-60 (about 45 mHz FFT). He has taken the time to drive= out of=20 the noise and got a doubtless positive reception. If i would have transm= itted=20 QRSS-60, it would have been "lost" time and energy, for him an= d for=20 me!
