I’ve been having this issue with my radio setup lately where it’ll perform like a champion on the digimodes, but after about 5 minutes WJST-X acts like it is receiving RFI. WJST-X seems to lose communication with the radio unit, and pops the Rig Control Error dialogue box.
I have tried troubleshooting over the last few days, including:
swapping coax
adding ferrites to the USB
Swapping for the DigiRig USB
Utilizing rig without ATU
Changing computers
The only thing I haven’t been able to isolate thus far is the DigiRig. Thoughts?
No, using the embedded USB-A ports on the computer. Thus far, I’ve used the coiled DigiRig USB-C to USB-A with the ferrites, as well as a regular usb with added ferrites, and then a regular USB router through a toroid. All have been unsuccessful
I also have an IC-7000 and a Digirig running WSJT-X with similar issues. I’ve tried all the suggestions found in this and other forums and none have totally resolved the issue. I think the IC-7000/WSJT-X combination is particularly sensitive as others have noted. I can swap out the 7000 for a Yaesu FT-891 with its Digirig with everything else being the same and have no issue. I too would welcome a solution!
The most effective solution is a common mode choke on the feedline - it prevents RF from making it back to the radio vs trying to deal with it in accessory connections. One of the less expensive ones that I came across is this model:
RF was traveling down the coax into the system and causing hell. I added a common mode choke make from a jump cable wrapped about 12 times around a FT240-43 toroid. Just made a flawless transcontinental QSO on 50W.
