I can think of 2 stations .. One problem with w-2/15 is 'we don't actually know the decode profile , with Op , we know 50% of the 256 bits need to be above the min s/n to decode.. randomly distributed or on block / block's ... wspr used to show , was it 16 sync points ? but would go with 1 , but what contributed to a sync ? Op15 was dropped a while back as the results seemed to be counter-productive on MF , LF was ok, but the qsb cycle allowed for 32 mins , with the extra -3 dB 73 -G. -------------------------------------------------- From: "g3zjo" Sent: Friday, February 22, 2013 1:50 PM To: Subject: LF: 630m WSPR2 and WSPR15 Distance > I remain unconvinced that WSPR15 offers much advantage over WSPR2 on 630m. > > Below are the distance records for the 2 modes as accurate as I can be > from the Data Base.
