I’ve paid for the Nicsure Patreon to get access to his new firmware for the Radtel RT-880G, and I’ve used his Linux CPS to flash it and load channels.
Having a Linux CPS alone is an amazing enhancement. The UI is not necessarily intuitive compared to other radios, but I’m getting accustomed to it. Most the functions I want from the menu are found by long-pressing the green button, and it shows you the shortcut key you could use. There are also posts about an extended manual that helps a bit, but I still found mismatches.
I have it beaconing APRS and receiving, but it still struggles to get a good decode. The stock firmware shows garbage decodes, but his one just doesn’t show anything for those failures.
It seems to have nice scanning, HF receive, and the spectrum analyzer.
