Xiegu G90 PTT issue, PTT not released

I use a Signalink usb interface and have no problems with any of my digital modes.

There was some posts about G90 configuration on our facebook page.

Please take a look and see if you have similar configurations on your end as shown by other G90 users :

Here is one screenshot from someone using Omnirig:

@pe1pux any update ? maybe now with V3.4 ? I got feedback that CAT command works great with G90. Please let me know.

Hi,

Unfortunately it's still not working for my G90.

My settings are:

And the log shows:

The PTT is enabled fine, audio is being transmitted, but the PTT is just never released. Frequency changes are also working fine.

I'm running firmware version 1.78 (Jan 19 2022) in my radio. Perhaps other people for which it is working are using an older version of the firmware?

The USB Serial device is an FTDI serial adapter, which is working fine for other digital modes apps.

I can work using my 7300, but it would be nice to have the G90 working for portable activities. If there is anything i can do in helping with debugging, please let me know!

Hi Erik. When you Test PTT ON/OFF on the settings screen - does the PTT OFF work?

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.

I suspect of something Erik.

Please go to VarAC.ini file and increase this parameter.

PortWaitTimeMs=100 --> 200

try again and let me know
