KPA100 remote w/o KAT100?

[Dan Schieler]

Hi, I'm proud owner of K2 SN 4426.  Have built this out as a QRP rig
with KBT2, KATU, KDSP, SSB, NB.  Ordering the 160 module today.  I also
want to have 100W capability but don't think I want to build it in the
rig, I'd rather put it in a EC2.
 
The main reason I don't want to build the KPA100 in the rig is that I
travel frequently and sometimes like to take my K2 with me.  I just
assume it is an effort to take out the top with the KBT and put in the
KPA100 top section.  Is my assumption correct?  Can I keep the 20W tuner
in the rig if I put in the KPA100 and just put it in CALP mode?  Can
this happen automatically so I don't accidently toast the tuner with
100W?
 
All of the posts I have seen regarding remoting the KPA100 always
include the KAT100, which I don't think I want.  Reason is, the only
time I'd use the 100W is when I'm home in the shack using mostly
resonant antennae but also I have my KW tuner in line as well.  I run a
linear amp when needed for DX and bad conditions which the KPA100 would
drive at 65W or so.
 
Therefore, can I just order the KPA100 and EC2?  Do I need a KIO in the
rig to interface with KPA?  I would want to interface the K2/KPA100 to
my N3FJP program so I would most likely do the dual uart cable I've seen
from the KPA100.
 
Appreciate the feedback.

The 20W tuner won't fit in the K2 with the KPA100.  But you can keep the
20W tuner in the K2 if the KPA100 is remoted.

The KAT100 is not required to remote the KPA100 into the EC2.  You need
a way to get the auxbus connection between the KPA100 and the K2.  The
KIO2 is the simplest way to do this.

You might try

for suggestions on how to remote the KPA100 into the EC2 without the KAT100.
