With a set of Baofeng PMR 446 MHz walkie talkie radios, the initial channel frequencies didn't match between: BF-88E and GT-22 models.
This can easily be fixed using CHIRP (a free, open-source tool for programming your radio. It supports a large number of manufacturers and models, as well as provides a way to interface with multiple data sources and formats).
I've been using the following version on (x)ubuntu 20.04 successfully without problems.
All working smooth out of the box:
CHIRP next-20230924 on Linux - Ubuntu 20.04.5 LTS (Python 3.8.10)
Follow the instructions on the CHIRP website:

Jumping out of an airplane is not a basic instinct. Neither is breathing underwater. But put the two together and you're traveling through space!
