I loaded the nicsure 5.14.01 firmware from the patreon onto my RadTel RT-880G. It changed storage stucture, so I needed to do a factory reset before installing. I found the RMS software does weird things importing chirp files or reading from the radio. I needed to sort out erroneous CTS codes, reverses, etc in the RMS.
The radio is receiving APRS really well off the outside antenna, and I’m seeing lots of good decodes.
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.
