Re: [wsjt-devel] Dsec control for WSJT-X

BTW, I should add that such a scheme has the potential for bad side effects if widely adopted (which seems unlikely) and if the error is not zero mean. It probably requires most stations to have accurate clocks. From: Deisher, Michael [mailto:michael.deis...@intel.com] Sent: Monday, May 6,

Re: [wsjt-devel] Dsec control for WSJT-X

It's not just the computer clock though.  You can have different delays on Tx/Rx depending on your setup. de Mike W9MDB On Monday, May 6, 2019, 3:38:33 PM CDT, Deisher, Michael wrote: wsjtx seems to have all the information necessary to  “crowdsource” the time interval

Re: [wsjt-devel] Dsec control for WSJT-X

wsjtx seems to have all the information necessary to “crowdsource” the time interval boundaries. For a portable station without GPS or Internet that could really help. If wsjtx published the dt values via IPC messages then it could be done outside wsjtx in a separate utility (i.e., figure

Re: [wsjt-devel] Dsec control for WSJT-X

I did a little test and had WSJT-X offset my WAV file by 300ms.  This idea would allow custom correction of Dt values beyond just accurate time.  So audio delays could be allowed for. I do believe this would be a very worthwhile addition to WSJT-X and may explain why people have been having

Re: [wsjt-devel] Dsec control for WSJT-X

Seems to me what could be done is to memmove the WAV data in the decoder in perhaps 50mS increments adjustable by an up/down where down means move it earlier (i.e. decrease Dt value).  This way receiving stations just adjust to try and hit the target value of zero.  Transmit is a different

OK Bill. It was just a thought and I knew the feature had been available before. Getting people to get their computer clocks accurate is like herding cats. Thanks and GL. Jay KA9CFD From: Bill Somerville Sent: May 6, 2019 11:36 To: wsjt-devel@lists.sourceforge.net Subject: Re:

In the older WSJT 10 program, there is a control labeled Dsec where the user's UTC clock reading can be adjusted to manually synchronize with your QSO partner's computer. I wonder if this feature would be useful in WSJT-X to help with FT8 decodes if your attempted QSO partner's computer clock
