Bug #11488 » uvk5.py

Potentially dangerous driver to allow OSFW-bd90ca3 uploads - Dan Smith, 08/23/2024 03:07 PM

 
# Quansheng UV-K5 driver (c) 2023 Jacek Lipkowski <sq5bpf@lipkowski.org>
#
# based on template.py Copyright 2012 Dan Smith <dsmith@danplanet.com>
#
#
# This is a preliminary version of a driver for the UV-K5
# It is based on my reverse engineering effort described here:
# https://github.com/sq5bpf/uvk5-reverse-engineering
#
# Warning: this driver is experimental, it may brick your radio,
# eat your lunch and mess up your configuration.
