I’m a new user of Digirig Mobile, which I bought to use with Yaesu FT-818ND transceiver. First I got it working on a PC with Windows. Now I’m trying on another computer (Asus C201) with Linux, in this case PrawnOS, which is Debian based.
In case it can be of help for others, I’m here explaining how I did it on Linux. So far I got fldigi to receive audio from Digirig. Perhaps someone also has advice about how to best continue.
Fldigi was installed from the command-line:
sudo apt-get install -y fldigi
Plugged in Digirig (using USB Isolator) to a USB port on the computer and found it in Linux, using the command:
lsusb
(on the second attempt, after changing to another USB port on the computer)
That way, three new USB devices were listed:
C-Media Electronics, Inc. USB Audio Device
Silicon Labs CP210x UART Bridge
Microchip Technology, Inc. (formerly SMSC)
Apparently, I can also find it in Linux using:
ls -l /dev/ttyUSB0
The response was:
crw-rw---- 1 root dialout 188,0 Jun 17 21:25 /dev/ttyUSB0
To get permission, I used:
sudo usermod -a -G dialout USERNAME
(where USERNAME was replaced by my real Linux username)
Now I was in fldigi able to configure the soundcard/devices (PortAudio), but saw that the audio input level was too high. Went back to the command-line to adjust that.
Found that <alsa_input.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.mono-fallback> has index 4, by using:
pacmd list-sources
The audio input level was in my case adjusted for index 4 by:
pacmd set-source-volume 4 7000
(the last number, which adjusts the level, could have a different value)
However, I’m from fldigi not yet able to control the frequency of the transceiver (despite trying to use the same settings in fldigi as in Windows, where it worked fine)
