Thanks for the idea.  

Yes, I have shutdown / rebooted everything.

Windows 10 WSJT-X decodes just fine, but, the Ubuntu WSJT-X will not decode the exact same decodes.   So, I think this eliminates the radio and audio stream from being the problem.

Hi Alan,

the first thing to check is that your receiver is set to a USB mode. Although the presence of signals on your screen capture at 14.074 MHz would seem to imply that is the case.

Looks like you are running a FlexRadio SDR, maybe  there is a lot of latency built up somewhere between the SDR and WSJT-X, have you tried restarting SmartSDR (if that is what you are using), and the DAX audio tool.

Hi Gene,

Sorry I am rather late to this thread but which ICOM radio are you using ?
On most early ICOM radios, the IC-V commands do not have a provision 
to directly change the frequency in the un-selected VFO. They must first
issue a VFO toggle command, then wait for ECHO msg then the CmdReply 
message indicating that the command was completed before changing the 
frequency and then toggling back to the original VFO.  This has to be done 
when using Split RIG. 

That may be why you are getting intermittent problems when switching 
offsets that quickly where the software has to actually change the un-selected 
VFO frequency. 

73,

Sam W2JDB

There are ferrites on the USB cable, but that is probably irrelevant because there is no RF being sent.  This is only occurring when changing the TX offset.  During all other activities, including transmission, everything works fine.  

The problem is intermittent though there seems to be a correlation with changing the offset quickly multiple times.

As mentioned this only occurs in split mode.  Fake it or no split does not cause this problem.

There are no other libraries loaded.  

As mentioned it appears that the software is sending a "change the frequency by 0.000xxx Mhz" rather than "change frequency to X.XXXXXX Mhz".  Is this what is occurring?

It is probably heavily out of date but I do have some experience in tracking down command issues on non-radio RS-232 and RS-485 systems.  I have no idea what is used with USB nowadays.  If anyone has a recommended method I could try to monitor the commands to see whether it is something happening on the computer side.

Hi Gene,

all CAT QSY commands are to an absolute frequency, but WSJT-X does monitor the current frequency and calculates the split offset based on that. Therefore incorrect or corrupt frequency queries could have the effect you are seeing. If you can reproduce the issue easily then the best step forward is to enable CAT diagnostics to track down what is happening. CAT diagnostics will create a very big log if you cannot reproduce the issue in a few operations.

To get a CAT diagnostic log put the attached file into your WSJT-X configuration files directory (on MS Windows that is the same as the log files directory "Menu->File->Open log directory" - if you are on macOS or Linux then let me know and I will tell where to put the log configuration file), restart WSJT-X, carry out the minimum actions to reproduce the issue once, then quit WSJT-X. It will have created a file on your Desktop called "WSJT-X_RigControl.log". Send that file to me (g4wjs <at> classdesign <dot> com) for analysis please?

Once you have sent the log file revert to normal operation by deleting the wsjtx_log_config.ini file.

Gene,

it was only a suggestion, CI-V Transceive Mode causes the rig to emit unsolicited CAT traffic which can collide with commands from a PC, that can result in very strange behaviour.

We have not had other reports of incorrect CAT control, as you describe, of the IC-7300 with WSJT-X v2.4.0. Are you using the built in Hamlib library for direct CAT control or one of the other proxy CAT control methods?

Gene:

You haven't said how you're implementing the CAT control of the 7300 but if it's CI-V via the 7300's USB port then you'll need to ensure that there's no RF getting into the USB connection - that can cause all sorts of random and intermittent errors on the USB bus.  Do you have any ferrites on the USB cable between the PC and the 7300?

Also, have you tried using the 'Fake It' option for split, to see if that makes any difference?

FWIW, I very occasionally saw a similar effect on my 7610 (when using 'Fake It' split mode) - the rig's frequency wouldn't always return to the correct 'base frequency' after the end of a Tx period, it would stay on the frequency selected at the start of the Tx period.  I changed the configuration of the ferrites on the USB connection between PC and rig, to put a more substantial common-mode choke at the PC end of the USB cable, and haven't seen the effect since.

For general HF work I choose to call CQ in the time slot with the strongest signals.
There is a benefit to having all the RX signals near the same level without one or more big signals in your RX.

As a WAG rather than sending a "set frequency to X, set split to Y" the software is sending "increase/decrease split by Z" but occasionally sends the "decrease by Z" to the base frequency rather than the split.  Choosing the band again in the drop down box appears to send a full "set frequency to X, set split to Y" command and everything goes back to where it should.  Until the TX offset is changed again.

There will always be a frequency change, as the frequencies of the FT4 'areas' are different from the FT8 areas.   As far as why its missing, have you tied doing a Frequency List reset?

Go into Settings -> Frequencies and RIGHT click in the list, from the menu select RESET.    You should then see a 20m FT4 frequency.

Hi Jack,

FT8 and FT4 use different transmit periods so are not compatible, they are used in different frequency sub-bands. The WSJT-X "Settings->Frequencies->Working Frequencies" table defines the frequencies offered on the main window pop up list, they can be mode and region specific. If you have upgraded from an older version of WSJT-X you probably need to reset the list to the current defaults (right-click the table body and press the "Reset ..." button in the contextual pop up menu that appears.
