Did you know you don’t need any additional equipment to leverage digital modes on the FT-891? All you need is the right cable and the right settings.
The following steps outlined in AA0O’s (now unavailable) blog post will help you assemble the cable.
The packet interface cable was pretty straightforward. Be aware you are working with very, very small wires. I followed the “use a lighter method” and it worked well enough. Make sure you hold the flame to the fire just long enough to soften it.How to strip real small wires
Give yourself enough wire length to work with. I was a little too conservative and it was a tight squeeze when I attached everything with electrical tape. Now that I have verified it works as expected I plan to solder the connections and use heat shrink tube to add durability.
To hook my new cable up to my rig I purchased a USB Type-C Stereo adaptor. Ensure the correct audio plugs are plugged into the appropriate spots on the adaptor. If you’re having problems at the end switch them up and see if that gets you going.
Apply the settings below to enable digital modes on the FT-891. I’m not promising these are the optimal configs, but they worked well for FT-8. I haven’t made it far enough to understand if these are the be-all-end-all digital settings for the FT-891.

I used my MacBook Pro and the WSJTX install was pretty straight forward. Do use the README file provided to walk through the additional installation instructions. If CAT control isn’t playing along ensure the baud rate in WSJTX matches the 05-06 setting.
For logging the AA0O blog suggests RUMlogNG. So far RUMlogNG has solved my problems for generating POTA logs, and integrating with WSJTX. MacLoggerDX seems to be a more robust (but not free) logging solution for Mac. I’m interested to see if I end up shelling out the money for a license as I get deeper into the hobby. For the time being free does the job.
Making QSOs isn’t straightforward at first. But as long as you see information coming in on the left side of the screen you can start to make some contacts.Making FT8 QSOs with WSJT-x on 20M
