Digirig device best suited for FT-897D, as well as a couple of other single band HF radio's?

Looking for a Digirig device best suited for a FT-897D, along with a couple of 10 meter and a 10-12 meter radio’s

The Digirig Store has what you want. Consider looking at:

Yaesu FT-8xx cords for Digirig Mobile – digirig

Digirig Mobile – digirig

For the 10 meter radios, you will have to give more information about the radio connections.

What @Constrainted said, I’ll just add that you’ll need to select Logic Levels configuration when ordering Digirig Mobile. You’ll also need a USB-C cable cable if you don’t have one at home.
