Use this firmware/code ENTIRELY at your own risk. This firmware is totally experimental, and at
times will go completely tits up (break your radio).

## Observed radio boot problems
After having two UV-K5(8) radios for a while now, and I don't know how many programming lead
insertions/deinsertions (lots n lots!) both radios are now having trouble booting up into either
the bootloader and/or the firmware.
After having two UV-K5(8) radios for a while now, and I don't know how many programming lead insertions/deinsertions (lots n lots!) both radios are now having trouble booting up into either the bootloader and/or the firmware.
The reason appears to be something to do with the the 3.5mm/2.5mm mic jack sockets or the volume control pot, most
likely the internal contacts in either/both of the sockets or the on/off contacts in the pot.
I suspect the reason being something to do with the the 3.5mm/2.5mm mic jack sockets or the volume control pot, either that or broken throu-hole plating in the PCB or such like.
Need to find matching replacements to confirm this though (or just temp short the terminals that are suppose to be shorted at power on).

# Radio performance
Please note that the Quansheng UV-Kx radios are not professional quality transceivers, their
performance is strictly limited. The RX front end has no track-tuned band pass filtering
at all, and so are wide band/wide open to any and all signals over a large frequency range.

But, they are nice toys for the price, fun to play with.
# User customization
You can customize the firmware by enabling/disabling various compile options, this allows
us to remove certain firmware features in order to make room in the flash for others.

You'll find the options at the top of "Makefile" ('0' = remove code, '1' = include code) ..

Sounds a lot/complicated but once you done it a couple of times you'll be fine (hopefully).
When you're editing the name, you can enter digits (0 ~ 9) directly without having to use the up/down
