[chirp_devel] [PATCH][px888k] Adding support for the Puxing PX-888K. Fixes, among others, #288

List of issues asking for support of the model: #3447 #1659 #379 #288

The code has been formatted to fully comply with pep8 requirements, which in my opinion in some cases makes it harder to read, but I understand and appreciate the need for a common standard in a multi-developer project.

Have a nice weekend. Leo
