Kevin, Fred,

Found the posts in the archive. The solution/work around was to turn CI-V
Transceive OFF.
In my case CI-V Transceive has always been off.  Don't know what  Fred has
set on his 7610.

I do see the lag in the frequency update on WSJT when tuning the radio VFO
but it always catches up and displays the correct frequency.

What Fred and I are seeing appears to be a different issue.

This is my take on what is happening from a 50k foot user's perspective.
Someone that can dig into the code may have a different take on it

The radio is tuned to whatever frequency.
Launch WSJT-X. WSJT-X initializes and reads the radio frequency.The
frequency display on the main screen is initialized and the correct
frequency is displayed. Another register/variable  within the code is also
initialized with the same frequency.

The user manually tunes the radio dial.
The frequency tracks correctly on the main screen of WSJT.
The mystery register/variable appears to be static and only gets
initialized at startup. This value is what gets used in logging the decodes
to the ALL.txt file and sent to external apps and servers via the UPD and
TCP/IP packets.

Logged contacts  have the correct frequency  which equals  the displayed
frequency on WSJT+ DF.


One additional quirk I am seeing is if the radio is tuned to a normal WSJT
FT8 frequency. WSJT is launched all is good as expected.
The VFO on the radio can be changed to another frequency and everything
appears to track correctly. All.txt and spots on PSKR and Hamspots have the
new frequency. If the VFO is tuned again, the frequency is not updated and
the All.txt and spotting apps still have the old frequency.


Shouldn't be too difficult for someone that is familiar with the code to
track the frequency variable that is used for the All.txt file, UDP and
TCP/IP packets and see what it is/is not doing when initialized and when
the VFO is tuned.


73,
