To summarize isn't it safe to say: "As long most of your DT times are less than 1 second you will be able to decode everybody else who is less than +/-1 second.  WSJT-X allows 2.5 seconds of difference so if both sides are off by 1 second in opposite directions that would be 2 seconds of DT and

Hi all, A number of comments and questions have appeared here recently concerning the parameter DT displayed by the WSJT-X decoders. K6AVP: Only a few have posted what range of DT’s they mostly see ... K9YC: My memory is routinely seeing DTs in the range of +/_ 200msec, with occasional ou

With 1.9.1 I saw a range of +/- 0.2-s. With rc5 I am seeing 0 to +0.35 and no -. I understand that this is caused by a bug that will be fixed when 2.0.0 is released. On Thu, Dec 6, 2018 at 8:36 AM George J. Molnar wrote: > Thanks John! > > There is nothing to be gained by tweaking the last milli

Thanks John! There is nothing to be gained by tweaking the last milliseconds out of timing. Sure, it looks pretty and appeals to the perfectionist in us, but as long as it -WORKS- call it good and have some fun. George J Molnar KF2T, Arlington, Virginia, USA Please note my new email: geo...

Al, I think the key question is are you otherwise getting satisfactory performance? Are you making Q's? This subject is starting to take on the tenor of the never ending quest for a 1:1 SWR. And as we used to like to say, "If the SWR is less than 10:1, call 'CQ'!" John On Wed, Dec 5, 2018 at

Only a few have posted what range of DT’s they mostly see when time.is (or something else) says their PC clocks are right on the money. Mine is consistently +0.35s. Do most peoples see something similar? If I slow my clock by 0.35s, while sync’d to gps and nist.time and time.is says it is right
