[chirp_devel] Baofeng UV-3R

Dan, thanks, that helps my curiosity a bit.

A number of things about the Wouxun made more sense after
someone had posted the datasheet for the microcontroller
which the vendor named "FRS-MCU".

I haven't looked yet to see if the Puxing, TYT, etc. are
using the same chip or same manufacturer.  Though I suppose
some of them could be using clones of this chip or that chip
is a clone of ...  (loop detected).

If you are willing to take the time to type it, I'd love to read it.

I suspect you are right. That pattern seems to show up in other products.
