JT65: I DO NOT confirm JT65 qso's anymore. After reading ( info sm2cew.com) and understanding
the true meaning of the DS decoder I got aware of this 'guessing' technique.
Therefore my opinion is that JT65 has no DXCC credibility.
Your lucky if you already posses a card with confirmation of a JT65 qso, because it was before I got
aware of this JT65 DS issue.
Now, this article on sm2cew.com is last updated June 2009 more as 4 years ago. The JT modes did evolve in time and this was more a issue with very very weak signals below -27dB and EME. Not shure if this counts for HF use of JT as well. But I thought I should share this as many are not aware of this article. Standard decode setup is "normal", but if you think your computer is able to do "deepest" search you could try it. I did try it but the article made me choose "normal" again. Actually I do not notice any difference, I'm still able to decode even the weakest traces in the waterfall.
The JT65-HF software never implemented the deep search. WSJT-X also does not implement that feature.
ReplyDeleteOk Paul, tnx for the info. I thought that choosing "deepest" would activate such a function. The article is last updated 2009 and I think it was more a issue with EME at that time. Interesting read though! 73, Bas
DeleteHallo Bas,
ReplyDeleteIk heb altijd al vraagtekens gezet bij deep search. Zowel bij WSJT-9 voor MS als bij de andere programma's heb ik nooit kunnen merken dat zwakkere stations er wel of niet beter gedecodeerd werden.
Dus ik gebruik altijd Normal.
