[chirp_devel] FYI for Wouxun KG-UV6D 199 memory channel radio

[Robert Terzi]

FYI, for the maintainer of the wouxun driver.  David Behar has done the work to
map out the memory format as well as the .tw file format for the newer
version of the Wouxun KG-UV6D radio.

This is a newer version with 199 memory channels and 2.5 khz spacing.

Note: the memory format and software between the earlier 128 memory channel HT's
(KG-UV1,2,3) and the 199 memory channel is similar but incompatible.  There have
been reports of people running into problems (including possibly bricking radios)
by using incompatible versions including .tw files from a different version of
the radio.

The wouxun settings including the band limits seem to be in range of the
writable memory area without much protection.  It sounds like using the
wrong version will unintentionally overwrite those settings with garbage
(channel data).  I've read that writing band limits outside the range
the radio is capable of will cause the PLL to fail to lock and the microcontroller
will then hang waiting.

Note: it may be worth mentioning on the chirp pages that the KG-UV(D)[123][PD]
driver is not compatible with the kg-uv6d.

I don't know if the UV6D radio sends a different identification or has any reliable
way of telling the difference.  I don't have one.  I'm just sharing what I've
seen on other mailing lists as an fyi.

Hope this helps,
--Rob

I've passed on to Jim a draft memory map of the radio's memory space and of the KG-UV6D TW file format.
