I was able to successfully see the sound card when completing the steps that Mr. Hays gave. The issue I have is going onto the n7nix scripts. After running the ./app_config.sh core, I no longer see the UDRC sound card. This was discovered late last night and I have not had a chance to troubleshoot these issues. For those
having issues did you continue run that script before testing the sound card? I will try to troubleshoot soon and open a separate thread for the issues with the n7nix config script.

My steps I used.

1 Downloaded Buster 2019-07-10-raspbian-buster.img
2 Used Etcher on MAC to flash image to a SanDisk 32G Card
3 Booted SD in Raspberry Pi 3B+ DRAWS (received July 2019) hat installed - Power through 12V DRAWS hat
4 Boot resized file system and entered United States - and Chicago Time then set password and then selected WiFi.
5 enable ssh - to be able to cut and paste commands.
6 Changed Hostname (N9TJX-Draws)
7 Rebooted.
8 sudo apt update -
9 sudo apt upgrade.
10 Rebooted.
11 sudo apt install git build-essential vim and nmap (- git and build-essential were up to date installed vim and nmap)
12 git clone https://github.com/nwdigitalradio/n7nix.git
13 cd n7nix/config
14 sudo ./image_install.sh
15 sudo apt --fix-broken install
16 reboot - Current Location
17 cd n7nix/bin
18 ./sndcard.sh -

Second that notion. There is a lot of what I consider unwanted fluff in this image since I don't care about packet radio. I would really like to have a clean image with only the necessary drivers and such and then I could install my own programs, and select the HF programs that I want to use. So perhaps a "minimal" image
that gets the DRAWS functioning properly on the RPi??

Hi Mike,
I can confirm that I am powering it via the 12 volt plug. When you write up your clean install, please could you specify which version of the buster image you use....
