I also have a 991 here.🤓However, I plan to keep using the 991 machine, even though it's older. The DSP chip and DX10 seem similar to those in the 857, so it shouldn't have screen display issues like that. It provides stable performance, excellent noise reduction capabilities, and sufficient power for features such as 144 and 430 frequencies, as well as modern functions like C4FM CW. The equipment is also fully certified.
