Hello Mike,

Sorry, somehow i missed to read your comment.
So far i didn't spent much attention on OP32 but if it is really 
comparable with QRSS-10, there will certainly be no chance at all for me 
to be decoded in VK.
Roger says WSPR can be compared to OP2. Is that correct?
So then we would come back to good old fashioned QRSS/DFCW as the only 
serious DX mode on LF, not to talk about VLF.
