Reverting from FW 4.83 to the Previous Release Version

My K3/P3 arrived Friday. I listened a bit, mostly
on SSB but some on CW. I don't recall any issues
with how it sounded to me.

Yesterday afternoon I finally got around to
installing the K3 Utility and P3 Utility on my
shack Win 8.1 PC. I discovered that MCU 4.83 had
been released and upgraded from the version my K3
#8004 was delivered with. All that went well --
and I noticed that the DSP firmware was updated,
too, from msgs on the LCD.

Last night I again listened to more CW and with
some settings the audio seemed "different", for
lack of a better term. Most likely this is due to
my newness to the K3 and some significant hearing
impairments (stone deaf in one ear and the "good"
one isn't so great), but I'd like to wring it out
and see if there is/was a difference.

So I'd like to try installing the previous release
version (4.67 or 4.76) on my K3 and do some A-B
testing. The problem is that since my K3 came with
the earlier version installed, I likely do not
have the needed firmware files in my computer to
be loaded -- though reading at the Elecraft
website it looks possible to do such a reversion
if you do have them in your computer

My questions: Are the needed earlier files
available for download, and if they are, which
files are they and how do I go about telling the
K3 utility to load them (I assume it's akin to
installing a beta version but as a K3 owner of 48
hours I've not had the opportunity to load beta
firmware).

Re: Reverting from FW 4.83 to the Previous Release Version

A followup on this: I've gotten lots of input and
help on this issue, on list and off. A local ham
with K3 experience, and who owns a KX3, came over
and gave my K3 a listen yesterday. All is good.
The issue was not in the new firmware but in my
still newbie-level understanding of the K3 and how
to set it up.

Yes. Check the web site download pages and there should be a Archive of earlier releases.

Also check for earlier betas. Beta with same number as production are same.
