Xeigu X6100 Cat Issue

Greetings all:

I have a Xeigu X6100 that I use for digital mode portable and I noticed that the CAT control switches from USB-D to LSB when USB-D is selected. Is there a way that I can modify the INI file to correct this? Any idea where that file might be?

Try this for USD_D in the cat file. I believe it will work.

Please LMK.

Just changed the USB-D to the following in the INI file.

[Xiegu X6100]

CmdType=HEX

PTTOn=FEFE70E01C0001FD

PTTOff=FEFE70E01C0000FD

ModeUSB=FEFE70E00601FD

ModeU-DIG=FEFE70E00608FD

ModeFM=FEFE70E00605FD

So I may have solved this issue.

The X6100 uses the name U-DIG not USB-D as in the settings on VarAC. So by changing the name in the Cat control .INI file to U-DIG, it looks to work. I think VarAC just couldn't find a USB-D so selects LSB otherwise.

Maybe someone else would like to confirm this by edditing their INI file to confirm.

Not sure I follow what you did. you can you share the changes you have made to the section of 6100 in the varac cat command ?

Not sure my reply posted so here it is again.

Change the mode from USB-D to U-DIGI in the INI file as below.

[Xiegu X6100]

CmdType=HEX

PTTOn=FEFE70E01C0001FD

PTTOff=FEFE70E01C0000FD

ModeUSB=FEFE70E00601FD

ModeU-DIG=FEFE70E00608FD

ModeFM=FEFE70E00605FD

I looked also on fldigi code. No indication for USB-D there

constchar *X6100modes_[] = {"LSB", "USB", "AM", "CW", "RTTY", "FM", "CW-R", "RTTY-R", NULL};

What I suggest is a short trial and error

This is the current USB-D command. The number id RED is the mode.

01 is for USB

05 is for FM

try to play a bit with the numbers maybe you find the right combo.

Please let me know if you find it.

Irad, recall that some older Icom's use a seperate CIV Command to turn Data On or Off. We need to get a 6100 owner to get the CIV commands.

Thanks for the advice. I tried changing the USB-D command from 600 through 610. The rig did cycle through all modes, but it did not switch to USB-D. As a workaround, I eliminated mode control from the CAT.INI file so the rig doesn't switch out of USB-D when changing bands.

I will let you know what the folks on the X6100 reflector come up with.

Thank you!

There are some Icom rigs that do not have a CAT command for USB-D explicitly under the 06 category. They actually use 1A 06 xx to turn Data mode on or off. Not all Icoms that have USB-D actually have a CAT command to enable this. We really need a 6100 user to get us the CAT commands.

Does X6100 has a usb-d mode ? I dont think so. Use plain UBS. simply select that option on the settings menu.

If so - please let me know and I'll fix the file so the 2 settings will end up with just USB for the X6100 to avoid confusions.

Or if we can find an owner of one of these to send us the CAT commands that would be of great help.

Hi Irad:

Yes, the x6100 uses USB-D mode for digital operation. Using standard USB tends to cause audio artifacts not to mention a loud "pop" from the internal speaker during transmission. I received the reply below from the X6100 reflector.

Thanks Irad. Tony -K2MO

But I don't want to dig into it just yet.

in the VarAC directory, called VarAC_cat_commands.ini

Gary et al:

I checked the VarAC CAT file and the USB-D command for the X6100 appears to be identical to ICOM. Seems Xiegu decided to use ICOM commands.

The USB command shown below works, but the USB_D command returns LSB. Maybe someone can shed some light on this.

Not having any of these rigs, does the 6100 have a discrete Data mode above and beyond USB??
