I agree with Johns' comments - did we ever figure out whether DFCW 30 versus qrss30 just helped a little more beyond  the co channel carrier issues that qrss may have, ie visual acuity and confirmed ID decoding a little better? Im guessing it may help by shortening tx periods against fades, maybe...

I remember having all sorts of issues with zero/small inter digit space dfcw that zl6qh ran on 136 when I was in 3D2. I just couldnt handle it, and ended up asking them to go to  on CW...

Ive a request - can someone ask someone to stop these horrid winds and the near continual Auroral warnings im getting since last September - please.... Well it is Sunday.
