I bought a k2 with every option and a battery pack. I also bought the external
at/100 and pa/100 in the twin enclosure.
My idea is same as yours qrp/portable with the battery pack and built in tuner
then at home with external amp/tuner combo.
I love mine and have completed it to my kenwood TS-590sG that I recently bought.
I have owned the k2 setup a few weeks I got it from a ham about 4 hours away
and I drove up to but it.
I believe it is every bit as good a receiver if not better than the TS-590 and
way better in HF than my TS-2000.
Buy one you'll love it- even if you don't choose to build your yourself it is
still a very capable rig.
I can have any rig in the world I want but I've found myself using the k2
consistently since I got it.

First I would say though that one of the big reasons to get a K2 is the
fun/experiences of building it yourself. If you are farming that out to
someone else, then I would be thinking carefully if K2 is the right option,
or whether a more modern design radio might fit the bill better (like KX3,
K3, or even, dare I say it here, a brand Y/I/K radio)
Assuming you go with a K2, then if you want to take the K2 portable QRP, you
need to think about whether you want to install the KPA100 in the same
chassis as the K2, or whether you want to put it in a separate enclosure, or
maybe even consider a separate amplifier like the KXPA100. Below are some
pros/cons of the different options.
KPA100 in same enclosure as K2:
+ one easy convenient fully integrated package
+ if you want to run the radio as QRP, just power it using the coaxial power
connector, and the KPA100 is bypassed
- have to lug the heavy KPA100 with you when you go portable
- if you want an ATU, it will need to be separate
- can’t put the 20W QRP ATU in the K2 enclosure (need to swap lids, which is
a hassle), battery option, etc. (actually, I would prefer to run the K2 off
external LiFePO4 batteries rather than put an SLA inside)
KPA100 in separate enclosure as K2:
+ full integration between K2 and amplifier
+ can leave the KPA100 behind when you go QRP
+ can put a 100W ATU in the same enclosure as the KPA100
+ can also equip K2 with 20W ATU, battery, etc. ready for portable operation
- takes more desk space
- if you want to go QRO portable, you need to take two enclosures
- can’t use the KPA100 with any other radios besides K2
K2 with separate KXPA100 amplifier:
+ can leave amplifier behind when going QRP portable
+ can equip K2 with 20W ATU, battery, etc.
+ flexibility to use the amplifier with other radios, like KX3, FT817, etc.
+ can put 100W ATU in same enclosure as KXPA100
- integration with K2 not quite as good as KPA100/KAT100
- may need to build extra keying circuit
- takes desk space/need to take two boxes for QRO portable
Other people on the list may have further comments based on their experiences
(I myself ended up going for the third KXPA100 option, mainly because I had a
KX3 already).

I am considering having a kit builder assemble a K2/100 for me to replace
my current station (see QRZ) Before making the commitment I would like to
chat with someone who owns a K2/100 and hear the PROs and CONs and any
issues. Additionally if there is a K2/100 owner in the Woodinville, WA I
would
love a demonstration. Woodinville is 25 miless NE of Seattle.
Please contact me offlist at _ardujenski@aol.com_
(mailto:ardujen...@aol.com) .
I will be operating it primarily as a base station but want the ability to
go portable QRP or to be able to operate off battery power during one of
the many power outages.
Thank you in advance for taking a few minutes to share your K2/100
experience with me
