Digirig DR891 and cables to connect to your Yaesu DR0891 HF amateur radio. These pass audio and control to/from your radio so you can remote control the rig and send/rx digital modes such as WSJTX, RTTY and other ham radio modes. They are $90 new. I used it for a few weeks then sold the radio. I decided that I'm not interested in POTA.
Must meet in SW Ocala on Rt 200 west of the interstate.
