I have the base K2, with battery pack and low-power tuner in one box,
and the 100-watt amp and high-power tuner in another. Very versatile,
and the battery powered K2 is ready to go on a moment's notice for fun
or emergency use. I also have the SSB, Noise blanker, and 160 meter
options in the K2. Consider those if you don't already have them. I
did put a dedicated KIO2 interface module in the K2, so I did not have
to depend on the amplifier for that functionality.
I have the KDSP2 DSP noise reducer. It works well as an automatic notch
filter, but only so-so for noise reduction. Not sure if I would do that
again. The KAF-2 audio filter can be a big help for the CW operator.
although careful choice and adjustment of the base K2 filters can
provide amazing results.
There are lots of places to find tutorials on how to build the rig as
"separates". It is easy. You will also need the EC-2 case kit and
another wire bail "foot". I chose to replace the K2 bail with the 1.5"
version, I like that much better than the taller version that comes with
the rig. I decided to leave the speaker in the base K2. Read the
manuals carefully before beginning construction of the amp in the EC-2
case so you don't do unnecessary work.
If your K2 does not have the latest upgrades, I would strongly suggest
that you purchase and install them before building the amp.

I have recently bought a previously owned K2/10 & am thinking of upgrading
it to the 100 watt version. My question is:
Is there any reason or advantage to upgrade with the amplifier & radio in
one unit or in the EC2 with the KAT100-2? I suppose it is a matter of how
it will be used but I guess I am looking for the experience of how others
use either or both configurations & why.
Being somewhat of a ‘Rookie’ ham, I frequently make hasty decisions based
on my lack of experience, so I am seeking the advice from the collective
experience of this distinguished group. J I am not solely qrp/cw but my
goal is to be operating mostly qrp/cw but I will also be getting a KX3
within the year & I also currently own a K1.
I thought the K2 would be my home station for now & would like to have the
power available if I wanted or needed it.
Any thoughts, comments or suggestions would be appreciated.
