K2 Mods list

[Robert Cochrane]

I'm the proud builder / owner of K2 No 3314 which I built in the
evenings at the start of my "retirement".

The reality was that I replaced one full time job with four part time
occupations, two of which involve global travel.

No regrets.  Never thought I would be able to visit Mongolia at
temperatures of 40C below and 40C above, or climb the volcanoes of
Nicaragua and El Salvador, or visit the ancient capital of Laos, or
see my old friends from my years in Asia again.

But the K2 has gathered dust under its embroidered felt cover for a
few years - there has never been time to get a temporary license for
these countries.  I now want to bring it up to the current
standards.  I have already carried out quite a few mods and have
parts sets for some more, but I really need a full list in date and
K2 number order of all the mods which a reasonably competent
un-solderer can make on the boards I already possess.

Can one of the Elecraft Elmers point me in the right direction
please?  Off list is fine unless you think the advice is of more
general interest.

I would not dream of describing myself as an Elmer, but is this what you
are looking for?

Or perhaps the list of K2 mods from the Elecraft order page?  They
list K2 serial numbers that began including each and you should be
able to check them off:

Many thanks to you both - the combination of the two is close to what
I was looking for.  I had already made a list from the Elecraft
component pages but was not sure it covered all the changes.

  Rob.

You don't have that much to add to bring it up to level.
*E850138 - The temperature compensation for the PLL Reference Osc.
**K2KEYMDKT - The Keying Waveshape Mod (also requires updated firmware)
The Extremely Strong Signal Handling Mod - see application notes - no
kit, but requires only 2 1N4148 diodes.*

That is all the official Elecraft mods to bring it up to the current
level.  There are unofficial mods as well, but those are usually for a
certain situation - choose wisely, if the intent meets your purposes,
then try it, but if the originator's purpose does not fit you, then
bypass it.  Examples of the latter are my K2 Fixed Audio Output mod and
my CW PTT for the K2 (see my webpage www.w3fpr.com).

73,
