By Paul Dordal, K2PMD
Introduction
Below is the specific digital set-up I have used
successfully using the XGGComms USB-Digimode-4 sound card with the Xiegu G90 HF
radio, running WSJT-X FT8 with FLRig (rig control) on a Raspberry Pi-4 Model B.
Additionally, for the FT-8 and FL-RIG software, I am using the latest KM4ACK Build-A-Pi download which you can find here (my download was on August 8, 2021): https://github.com/km4ack/pi-build
