I think it would be difficult for the developers to address every rig out there and every circumstance. I consider the software a gift as I did not have to pay for it and I am glad to put some effort into experimenting and reading available documentation to see what works best for my situation. There are a lot of forums, posts and videos posted on the web by Hams discussing such topics specific to WSJT-X.
The manual does address “Fake It” by basically saying each user should choose what works best for them: “Split Operation: Significant advantages result from using Split mode (separate VFOs for Rx and Tx) if your radio supports it. If it does not, WSJT-X can emulate such behavior. Either method will result in a cleaner transmitted signal, by keeping the Tx audio always in the range 1500 to 2000 Hz so that audio harmonics cannot pass through the Tx sideband filter. Select Rig to use the radio’s Split mode, or Fake It to have WSJT-X adjust the VFO frequency as needed, when T/R switching occurs. Choose None if you do not wish to use split operation.” “On the Radio tab select Split Operation (use either Rig or Fake It; you may need to experiment with both options to find one that works best with your radio).” “Be sure that your rig control has been set up for Split Operation, using either Rig or Fake It on the Settings | Radio tab.” It is not my intent to offend anyone. It just seems that this group, which I thought was intended for software development issues, such as bugs in the actual software, has been steered towards answering questions that are addressed in the manual or problems resulting from operator error (clocks, notch filters, QRM, etc.) I may have misunderstood the purpose of this group so I could be way off base. 73, Rebecca, N4EFS From: Paul Kube [mailto:paul.k...@gmail.com] Sent: Monday, March 4, 2019 6:07 PM To: marting0...@gmail.com; WSJT software development Subject: Re: [wsjt-devel] VFO-B behavior " perhaps there should be a note in the User Manual that, at least for Icom rigs, the 'Fake It' split mode is preferred/recommended?"

Some years ago, when I first tried using the 'Rig' mode with WSJT I found that the time taken to switch VFOs (from A to B in my case) and then to re-tune the newly-selected VFO with the desired offset (eg. +1kHz) was significantly longer than just re-tuning the active VFO, presumably because there was a longer command sequence to be received, processed and then actioned by the rig. The delay in the rig switching VFOs and then re-tuning was resulting in the transmission not starting until (IIRC) some 2-3secs into a Tx period. I would assume that using the 'Fake It' mode would work equally well irrespective of which VFO was the active one, so perhaps there should be a note in the User Manual that, at least for Icom rigs, the 'Fake It' split mode is preferred/recommended? -- 73, Martin G0HDB --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
