I can also add backup to that as well - I have K3 SN 20 fully upgraded.
It may not be relevant to the initial question, but the same thing
applies to the K2 - yes, there was a borad change at SN 3000, but
upgrade kits were available at modest cost to bring the older board up
to the same level except for minor and inconsequential differences. The
K2 upgrades continued through about SN 4660 and after that no further
upgrades were made. The result is that even the lowest K2 serial number
can perform just like a brand new K2 thanks to the way Elecraft has
handled upgrades. If you would like to compare my SN 20 K2 against a
brand new K2, just come over to my workbench - I can show you that the
performance is equal.
No model number changes that require you to purchase a new transceiver
to get the benefits of the change - just get the upgrade kit and install
it and you have a new and improved transceiver.
It is just the way Elecraft does business.

Just to back Mike up on his remark, I own K3 s/n 24 and have all the
mods installed as well as up to date firmware. AFAIK, this K3 is
roughly equal to all others that are up to date.

Dick -
IMO, not as useful as you might expect being that an early serial number is
fairly likely to have been brought up to current production standards. That's
unique to Elecraft as far as I know.

Is it possible to tell from the Serial Number when the unit was manufactured
and if there were any upgrades or mods made after that S/N ?
If one is looking at buying a used K3 or KPA500 then that info would be
helpful in determining a price.
