WSJT-X and FT-891

Followed the Digirig DR-891 Setup Manual step for step. Everything seems to work until I Enable TX. When I enable Tx i get two error messages.

  1. Error in Sound Input - An error occurred during read from the audio input device.
  2. Rig Control Error. I opened the details window and it states a Hamlib error.

Using the Digirig USB cables with Rf chokes on them.
Anyone have an idea how to fix this?

A good common mode choke on the feed line will take care of it.
Palomar Engineers stuff is good, but homebrew choke based on ferrite mix 31 may also work.

OK, you are saying a choke on the coax line going into the FT-891? This has nothing to do with the hamlib?

Yep, the RF coming back on the braiding of the coax kicks out the USB connection and then you get peppered with error messages. You can try sending at 1W and see if you still get any errors.

Many thanks K0TX! Dialed the power output down to 5 watts and all is fine. WIll install a feedline choke.
Appreciate you.

Yes, wsjtx is hypersensitive to rf unpredictability. try using a dummy load and see what happens. should work okay, 73 Ed w8eo
