Digipi with Digirig and Xiegu G90 | G90 Stuck in Transmit

[badukp]

I am trying to setup the Digipi to work with my Digirig and Xeigu G90.  I connected all the hardware, started "WSJT-X", and the G90 started transmitting and would not stop.  I am getting the error message shown below:

 

I connected to the digipi using ssh, and searched for "rig_set_conf", but did not find anything.

I did some searching online, and it appears that the "flrig" configuration can cause issues.  There are two files in that directory that look pertinent to this issue.  One is the "flrig.prefs" and "IC-705.prefs" files.

The "flrig.prefs" file originally contained the line "xcvr_name:IC-705".  I changed this to "xcvr_name:G90", restarted the digipi, and still have the same problem (G90 transmits continuously).

Do I need to replace the "IC-705.prefs" file with a "G90.prefs" file?  

Other pertinent info:

My WSJT-X configuration is shown below:

I also turned the power down to 1W on my G90.  I am using several chokes on the coax, so do not believe that RFI is an issue.

Note, that I did see Craig's previous post with a digipi configuration change:

I made this change to my digipi, and it did not solve the problem.

Hi Badukp,

Let's back up a bit, about WSJTX, are you using flrig for rig control? 
i removed that Initialization option from 2.0-1.
FLRig, and Rigctl should not be used in conjunction with WSJTX unless
you know how and why to use them.
Generally speaking they just grab the rig and cause problems and you
can't use the rig directly with wsjtx.

rigctld is only used with SSTV and pat, at this time.

wsjtx is setup for an ic705 by default, so you need to tweak wsjtx after
you start it.

So making sure flrig/rigctld aren't running, configure wsjtx using a
xiegu howto.  Click SysInfo to make
sure there is a device file (ttyUSB0 or ttyACM0 listed), and configure
wsjtxt.  once working, press
[save configuration] on the digipi home page to save your updates to the
SD card.

if it helps,

Hi Craig,

Thank you for your reply.  I configured WSJT-X, shown in screen capture above, based on "how to" videos for the Xiegu G90.  When that didn't work, I searched the internet and found a lot of references to flrig, and went down that path.  I didn't check to see if flrig is running or not.  Dumb mistake.  I am using the latest digipi release, but will check anyway to see if flrig is running.  

In any case, I did configure WSJT-X for the Xiegu G90 and it does not work.  The error references "rig_set_conf" and "icom".  I don't know why since I selected the Xiegu G90 as my radio.  I did click on SysInfo and saw the device file listed.  Do I need to save the configuration and restart the digipi?  Or should it work without saving the configuration, and saving is just for convenience?

it should work w/o pressing [save configuration], that just commits whatever changes
you made to the SD card for next reboot.

Let's see the entire wsjtx error if there is one.

it's really between wsjtx and the g90.  select hamlib, xiegug90, device ttyUSB0, unknown baud rate

I know we have g90 users on this list too.

help me remember if the g90 has a usb port, or if you're using some sort
of digirig-mobile interface?   I don't have a xiegu here.

cool,

Since I previously made changes to the configuration, I re-imaged the SD card.  

The lower portion of my initialization are shown below:

I configured the WSJT-X the same as I did previously.  The radio still starts to transmit immediately after starting WSJT-X, but now the "Test CAT" is green and there is no error there.  When I press "Test PTT" that button is red, but no errors are displayed.  I looked for an error log, but do not see one.

Photos of my setup are below:

I searched online and saw that the line in/out levels can cause problems, but I have them set at 50%.  This is the value that I saw recommended by others online.

Below is a screen capture of the WSJT-X settings.  It looks fine here, but the radio is stuck in transmit.

[badukp]

The radio is in receive mode until WSJT-X opens, and then it stays in transmit no matter what I do.

The setting is PTT via CAT, but do the audio settings in WSJT-X make a difference?  I left them at the default settings.

Attached is a video of my WSJT-X.  It shows that there is decoding etc, but I do not see that any signals were decoded (no decoded text from received signals etc).

Haven't read through all of this, but it looks like you have hardware flow control turned on. This will likely cause the COM port to raise RTS when WSJT initializes, and that will force PTT on the DigiRig. Try setting that to None.

[Craig]

In one of the pictures, DigiRig is connected to the keyer, so there is no serial/hamlib/data
connection to the Xiegu.  If this is the desired configuration, select "RTS" for PTT, instead
of "CAT".

And Scott is right, if you try to use hamlib, it opens the serial port for hamlib communication
which raises RTS which engages the keyer/PTT on the DigiRig, which is what it's supposed
to do in that configuration.

Doesn't the Xiegu have a USB/serial port?  Is the DigiRig mobile necessary?

cool,

Are you referring to setting the "Handshake" to "None"?  I tried this, and the transmitter is still stuck in transmit.  

[badukp]

Hi Craig,

The keyer is sitting on the power supply next to the G90, but there are no cables connected to the digirig.  Just the keyer out goes to the key in for the radio.  The G90 does not have a USB port, just serial in (by the headphone jack) and an "AUX" in jack on the back of the radio.  I am new to digital and don't know what I am doing right now, but the majority of folks that I have seen online using the G90 use a digirig.

[badukp]

I changed the "DTR" setting to low, and one of the audio settings.  It is nolonger stuck in transmit, and I can receive signals.  The only issues with the current configuration is zero output power.  I made sure that the G90 has "line in" selected, and the gain is set appropriately.  In WSJT-X, I tried setting the audio out to the same selection as audio-in, but that did not fix the problem.  

[badukp]

Success!  The setup is up and running with ft-8.

Thank you Craig and Scott for your help!

[Stephan Forth]

This is great. I'm fighting the same battle with my FT-817ND.

Can you please post a screenshot of your configuration?

Hi Stephan,

Screen captures of the "Radio" and "Audio" tabs are below.  I watched quite a few videos of people setting up their G90 radios with a digirig.  My configuration is different than the videos that I watched.  I set the "Force Control Lines" -> "DTR:" to low.  All the videos that I watched, they said to uncheck both "DTR" and "RTS".  Thanks to Scott for the hint that led me to this.
