[Elecraft] Fw: K2 and confused

[n0jrn]

 OK gang:

 I've about finished the build on my K2.      As I look forward and consider
 the options I've bought,  I'm puzzled over what I really need.

 SO,       figured I would put it to the group and get some advise.

 I bought the KAT2    &  the KIO2  originally.

 Changed my mind half way in and decided to go with the 100W upgrade.
( KPA100 )  Also purchased the KAT100-1.

 I understand the KIO2  is built in to the KPA100.     This makes the KIO2
 kit I bought excess to my need.
 ( I think )

 Also,     the KAT2  will be excess since I bought the KAT100-1.
 ( maybe )

Now for my confusion.

I've seen some posts in the archives from folks who have installed the
KAT100 in a case with the KPA100.    This allow them  to keep their
K2 as a QRP rig and hook up the amp etc. when they wanted a
 little more power.

 For those of you who have done this,     did you install the KAT2  and the
 KIO2  in your QRP rig  ??

 Are you running the QRP rig through the KAT100 and switching out the amp??

 IF you switch out the amp and want to run digital QRP will the KIO2  in the
 amp still work??.

IF  the KPA100 is installed in the rig,    can it be switched off and still 
run the rig
QRP or is it strickly a QRO rig ??

 I guess I'm looking for who done it and how ya did it to give me some
 guidance.

It would be cool to have the QRP rig with all features and hook it up to the
KPA100 /  KAT100  for contesting etc.

Are the KAT2 and the KIO2  truely excess now or should I install them ???



 What cha think ??
