K2 FW questions

[Jon-2]

In my continuing efforts of rediscovering my K2,  I'm wondering how
badly I want the current FW versions.

I currently have 2.01f and 1.02,  not sure what/if it needs one the SSB
version is.   I don't seem to be able to find a revision list of
versions back down to mine,  just what's written up for the current last
couple of 2.04 versions.

It's a 10W K2,  (embarrased to not remember my s/n!) have done a lot of
the upgrades and fixes probably up to the '04 or so point in time. I
have a lot, but not all of the options,  antenna tuner, SSB, 160m/RX,
NB, KIO2?.... No AF or DSP.    So, I'm wondering what feature additions
am I missing,  or am I pretty much OK as is?

Thanks...

My S/N [4398] is on a tag on the back of the K2. :-)  Mine is a 10W,
ATU, SSB [which I've never used, no mic], AF filter.  No DSP, 160, or
other accessories.  It was last aligned by Don, "The K2 Master."  It
works perfectly, I use it on CW with my AlexLoop, mainly on summit
activations and QRP field events.  So far as I know, it has the original
MCU FW, it's buried in my SOTA Go-Bag and I don't have time to dig it
out and fire it up to check right now, game about to start. :-)

For quite awhile, with the KPA100 and KAT100, I used it on RTTY.
Finally sold the amp and ATU when I got tired of that.

I'd guess that you're just fine and "if it works, don't mess with it"
may be the applicable maxim.

Jon,

Go to the Elecraft website. Click on the Manuals and Downloads link. Scroll down to the K2 link and click that. The first box is the K2 manual. In the box to the right of that is a link to older manuals called Manuel Archives. Click on that and scroll down to the K2 Fimware box. 2.01 is the only one listed. Click on that.

Hope this helps.

Jon,

The major firmware upgrade was from MCU version 1.xx to 2.xx.  Since you
have 2.01, you may not have any need to upgrade if you are satisfied
with it.  Your K2 will work as well as any other with that firmware version.
The first upgrade from 2.01 was to 2.03, and I am sorry to say that I
have forgotten what the added features were in that upgrade.
The change from 2.03 to 2.04 was mainly to support the more recent
upgrades and options - the K2 Keying Modification and the addition of
the K60XV option both required firmware changes.

If you have the K2/100, I would recommend the firmware upgrade and the
addition of the K2 Keying Waveshape Mod, but if you have the K2/10, you
may be happy with what you have now.

BTW, the K2 Keying Waveshape Mod is not currently available from
Elecraft, but if you want to install it, I can tell you how in a
separate off-list email.  I have already published it on-list, so you
can find it in the archives.  If you have the K2/100 (or drive an
amplifier with your K2/10), I highly recommend you add that mod to
eliminate keyclicks that are not obvious with the K2/10, but become
troublesome when an amp is added.
