Doug,
I just bought some cables from Denis @ Digirig?
They work for the x5105 as well as the G90. I also got the Digirig itself as the CE-19 was just too wonky for me. The cables and digirig are pretty compact and I will be bringing them camping with me at the end of the month.
I like that it works with multiple brands of radios - just in case another radio follows me home.
Denis was super awesome and reached out to me to see how everything went after I ordered. I'm a new ham and he helped me with a few of my problems. Like my high SWR cutting my FT8 transmissions (I have my x5105 set to limit power to 2.5:1 SWR - I'd love input on this BTW ...should it be lower?), helping my configure omnirig, etc..? I'm running 5 watts from my apartment deck and hitting the east coast with a homebrew 49:1 balun with about 25' of wire in an inverted U shape, tuned with a nanoVNA.
Here is a photo of my setup!??

Best of luck!
