A very surprising little guy!? Fldigi works properly with a few tweeks on the alsamixer.? Run your USB cable from the Signalink to a port on your multiple USB adapter and you are on. I didn't check on FT8 because I need to find FT8 software.? Also, for you Arduino folks, the zero 2 W works like a charm with it.? To get Arduino just do the following from the terminal:
sudo apt update
sudo apt full-upgrade
sudo apt-get install arduino
After a few minutes, the Arduino shortcut appears on your monitor. I have so far used several canned programs from the Arduino book and they have all worked as shown in the Arduino book.? Use the examples folder for the canned programs.? I am using a 5 V, 3 A power supply, a 10 inch HDMI monitor and a generic keyboard and wired mouse.? Power to the Arduino UNO is a 9 V, 1 A supply. Happily, the Arduino UNO has a voltage regulator to provide 5 V and
3.3 V.? As you might not know, the zero 2 W has a faster and more efficient processor. The zero 2 W is so small a visitor may wonder where it is but it does the job. Put it in a small generic box and it will get lost on your bench like mine, best 73, KK4AC, Charles
