K2 Outboard Amplifier options

[Curt]

My K2/10 is most times sufficient for DX.  But, sometimes it would be nice to have 50-100 watts.  Would rather not cram a KPA100 inside the K2, am wondering what options others have found useful recently.  Have encountered some references to installing the KPA100 inside a separate box, but seems there is a lot of wiring to run between the two boxes.  FWIW, I use a manually adjusted tuner.

Curt,

Not a lot of wiring at all.  There are only 2 cables - one is the coax
to connect the KPA100 to the base K2 (yes, you have to drill a hole into
the rear panel of the EC2 enclosure to accept a BNC jack.  I would also
suggest that you solder the header that normally is placed on the RF
Board onto the back of this BNC jack so you can plug in the normal RF
input cable to the KPA100.

The 2nd cable is to connect the KIO2 in the base K2 to the KPA100.  It
is built just like the cable shown in the KAT100 manual - yes I know you
will not have the KAT100, but the cable instructions are in that manual,
and you can download it.

So two cables to connect and disconnect, and that is all.

Curt...

     The K2/100 PA fits nicely inside the K2...(my experience)...and if
you try it, you will find it is not a "cram" job. I think it would be
much more convenient than trying to run things "outboard."

It takes 6 screws and about 2 minutes flat to swap out a KPA100 for the K2 cover with the KB2, KAT2.  I have entertained outboarding the KPA100 but is is so much more convenient to have the KPA100 right on top.  Operating it as a QRP K2 is easy - just power it with the K2 power (not the powerpole on the KPA100) and you have fine tuning all the way up to 15W.  You hear a DX station and need more power, turn the knob and you are there and does not need the desk space of the EC2 and without the expense.  Want to take it to the field as a K2/10 - takes just a few minutes to put in the K2 cover.  It does take longer than an outboard KPA100 by about a a minute and a half and $180+ less money (and yes you need a KIO2 with the K2 cover to connect to the outboard KPA100).  I am happy with this set up until I find $200 burning a hole in my pocket waiting to be spent.
