Of course one does not want to reduce sensitivity to weak sig

Hi Steve and Joe,
Thanks a lot for the compromise solution in r6080, it is really appreciated.
Going to make tests with it shortly.

Hi Igor and Steve,
Perhaps it's worth mentioning
Hi Igor and Steve,
Perhaps it's worth mentioning that our advice for all WSJT-related
programs has always been to disable the receiver AGC (if possible) and
turn the RF gain control well down, thereby minimizing AGC action. If
you do this and follow instructions in the User Guide about setting
Hi Igor,
Since this may be of interest to others, I’m copying this reply to the list.
First, I’d like to echo what Joe said earlier. If you are running in JT65A mode
and if your search range is the same for all cases, then you should see
identical results on all platforms and operating systems
