Yes. I will try it. Thanks for help.

Hi Clovis,

would you like to try WSJT-X v2.3.0 RC3 which you can download from here: https://physics.princeton.edu/pulsar/K1JT/wsjtx.html or here: https://sourceforge.net/projects/wsjt/files/wsjtx-2.3.0-rc3/

No error messages.

Hi Bill,

Thanks for the return. I can only transmit using the RIG option in split configuration.If I use NONE or FAKE IT, the TX is stopped and is not completed.

Hi Clovis,

more details please? Which version of WSJT-X are you using? How is your rig connected to your PC for CAT control and for audio? Do you get any error messages from WSJT-X when it does not transmit correctly?

I use an old Icom IC-756PROII and WSJT-X for FT8. Until a few months ago, I used it without Split and it worked very well. I noticed that now I can only maintain the TX period using Split mode. Otherwise the TX drops. Another observation is that although I determine on the radio the TX and RX frequencies for split, the radio changes to a frequency 0.50 below for the TX. Example: RX: 14.074.00 and TX: 14.073.50. I don't think there's anything similar reported here. So I ask if anyone could clear this up.

Hi Clovis,

please explain what happens when you say "Otherwise the TX drops".

Selecting on of the "Settings->Radio->Split Operating" options in WSJT-X allows the software to adjust your rig's Tx VFO dial frequency *and* the Tx audio tones to keep the tones within the optimal part of your transmitters bandwidth. This both allows you to transmit at any selected offset and also greatly attenuates any audio harmonics generated by overdrive of the transmitter's Tx audio circuits. You should expect the Tx VFO dial frequency to change when you select different Tx audio offsets, this is normal behaviour.
