This sound card does not require any drivers. I chose a SABRENT USB Audio Sound Adapter for the audio feed between the PI and the radio. The PI interfaces to the FT-891 with a USB cable for Rig control and a 6 pin DIN cable for the audio sound card feed. After a few emails back and forth with Jason, I was able to get everything configured correctly. This was a single script that you ran on the Pi after building it, “ git clone $HOME/pi-build & bash $HOME/pi-build/build-a-pi” This downloaded and installed all of the programs that I wanted on the Pi. I then found a new video that Jason had put together called “Pi Build V2”. I spent several days building the basic computer, one program at a time and troubleshooting issues with the LINUX code. I had seen several videos by Jason, KM4ACK, he has a Youtube channel full of Ham Radio related information. Any mistakes you make later, you can start at this point again, instead of building the microSD card and reconfiguring the Pi all over. Next select “7 Advanced Options Configure advanced settings” then select “A5 Resolution Set a specific screen resolution” scroll down and select “DMT Mode 82 1920×1080 60Hz 16:9”. In the Terminal window Run “ sudo raspi-config” and select option 3 “Boot Options” then B4 “Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user” select This brings you back to the main page. The first is to set the Pi to “auto log in” and the second is to set the screen resolution. You will need to make 2 additional changes to the software. After running two scripts called “ sudo apt-get update” and “ sudo apt-get upgrade” the Pi should be at the very latest version and ready to load additional software. Once the initial setup is complete you can then us VPN software to remotely connect to the Pi computer from your home computer. The software takes you thru steps to setup the screen, create a WIFI connection and configure interconnection protocols. You need a monitor and keyboard plugged into the Pi for the initial steps. Once that is complete you insert the microSD card in the Pi 4 board and boot the system up. This is kind of like loading Windows 10 on a computer. You need to download the latest version of Raspbian software and using a program called “balenaEtcher” burn the software image to the microSD card. I set up a test station on the bench and began building the Pi software. I chose a Raspberry PI 4 with 4Gig of Ram and picked a 32G microSD card to hold the programs. The first big step in building the Go Kit was to select the Raspberry PI board that I wanted as the computer. After watching some videos on field radio operations by Julian, OH8STN, I decided to add the Portable Zero rails and installed the Raspberry Pi4 inside the Portable Zero battery box. For the HF rig I selected the YAESU FT-891 radio for its size and quality. I also wanted it to be compact and fit in a backpack with battery power or a small case. I wanted to build a “Go Kit” for field activation using both HF voice and digital modes. Write-up by: Bob Nazro Amateur Call W1RPQīuilding an FT-891 Field Rig with Raspberry PI computer.
