I am cross posting this to the blind-hams list for info only.  Please look
at his last comment regarding going back to former firm ware versions.  Very
73 all.

I have downgraded from V1.04 to V1.03 successfully so it is possible to
backtrack.
Hope that helps,

Dick, after having spent a career in software/firmware engineering,
I agree with your overall assessment. However, there are also
risks associated with upgrading. There is a slight risk that the
upgrade will introduce a new bug. There is a risk the install
itself may not play well in some radios. Also, someone else in an
earlier thread here mentioned that the Kenwood firmware installer
will not allow you to downgrade to an earlier release. (Can anyone
confirm this? If it is indeed the case, I believe Kenwood has
made a mistake in enforcing such a prohibition.) But, because of
these sorts of risks, I generally avoid putting in an update for
the first week or so in order to allow time for the early adopters,
who act as the guinea pigs, to report their results.
