Frank,

I did the install on 3B+, so I needed unpack and setup a Pi 4 (4GB) to verify it ran there as well.  I just moved over the SD Card to test.

Installation (using the 3B+)

    git clone https://github.com/nwdigitalradio/n7nix.git
   cd n7nix/config
   sudo ./image_install.sh
   sudo apt install --fix-broken
   sudo apt update
   sudo apt upgrade

After moving the SD Card to the Pi 4

pi@draws-buster:~ $ uname -m
armv7l
pi@draws-buster:~ $ aplay -l
