Hi Irad, Sorry for the late response. I've tested some further with the G90. When testing PTT ON/OFF it works just fine as expected. When calling CQ the PTT is kept enabled, so that's not how it should be. When using the tuning option in the Vara software i noticed the G90 is also set to TX mode, and stopping a tune cycle does not release the PTT mode. Then i noticed that it works fine as soon as i disconnect my CAT cable. Now the PC is only connected using the sound card interface. Although VOX is disabled the set is keyed-up when i start a tune cycle in the Vara software. This time the PTT is released as soon as i stop the tune cycle. I find it strange my G90 starts transmitting without CAT so i assume this is a software bug or feature in the firmware (v 1.78) of my G90. When the G90 sees audio on the line in of the data jack in the back the set is set to TX. Which is convenient when you leave your CAT cable at home while in the field :-) As a workaround i can leave the CAT cable disconnected and use the magical TX triggering as soon as the Vara software sends audio to the soundcard. The downside is i have no automatic frequency control for QSY. When doing the same kinds of test with Winlink it works just fine in both cases, CAT cable connected or disconnected. Only difference in settings is that i selected the ICOM 7200 as a rig since Winlink has no G90 option. I've tested VarAC with the ICOM 7200 option, but results are the same as with the G90 selected. For other reasons i installed everything on another laptop with a fresh Windows 10 install and made sure the FTDI (usb-serial) drivers where up-to-date. 73 Erik
