[Elecraft] Reverting from FW 4.83 to the Previous Release Version

[Phil Wheeler]

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).
