[UK-CONTEST] RSGB 80m CC DATA

[marc.tinkler at yahoo.com]

Interestingly.. I compared how my MMTTY (with Writelog) was doing compared to my other Digimode SW. MMTTY was coping better and printing copy whereas the other one was mush a lot of the time. I know MMTTY has various settings that are supposed to help with all the different kinds of signal distortion etc... but I'd never seen it in action before.

I think the proof was the fact that I called a number of stations, who I was printing quite well (and would have heard me within as S point or so.., but I just got endless QRZ? or CQ's back at me... that's when I decided to do soemting else :-(

Same inability to decode a lot of the signals here.  After looking for
incorrect settings in the software I decided it must be phase distortion.
PSK31 was far better from this point of view with solid copy of virtually
all signals.  But I think lots of people (including me) have given up on
PSK31 as being too slow for contesting.
