K2 upgrade notes not found on Elecraft site...

[ke9uw]

I’m not finding the several firmware upgrade notes. I see where you can buy the new firmware chip, but not finding why you would want to.
I have noticed that the Elecraft site somehow has info, but sometimes it is difficult to find it...or it’s no longer there. Don’t like to see the latter.

Does this link get you there?

https://elecraft.com/pages/k2-mods-and-notes

I did not find a list of features incorporated in the various firmware
updates.

That’s an informative link. But what is missing from the upgrade firmware
listings is the history of the upgrades.  And they are not shown in the area
where you buy the upgrade chip. On the K3, the latest firmware upgrade lists
all the upgrade information from the beginning. Not so on the K2 upgrades.
Only the last firmware upgrade lists the details for that upgrade. And it’s
not easy to find...I forget where I saw it as I write this.

Chuck,

I found an old copy of the K2 firmware update instructions with brief
descriptions of prior versions' feature changes using the Wayback Machine
(aka archive.org).

https://web.archive.org/web/20090822034804/http://elecraft.com/

Once at this archived page, select Manuals and Downloads in the left hand
menu, select K2 manuals,
and scroll down to the link titled "2.04 K2 Firmware Notes."  That lists the
features of the Rev 2 firmware
succession.

The most recent firmware version, I believe, is 2.04R.  The instructions for
this version have a more limited history of changes.

I hope this helps a bit more................

Mike, K8CN

 Hey.  Thanks!  That is a big help.  I've been following along in the shadows as I built my K2 in 2000 and have been looking at bringing it up to date.  I kept up with updates number of years but I'm not exactly sure where I am and where I need to go with it.
