[Elecraft] Question about the K2

[Jim Wiley]

Eric


I have my K2 set up this way.  The "base" K2 has the internal tuner, 
battery pack, SSB, NB, and so on, including the KIO2 and the 160 meter 
option.   This is my "go bucket" version for emergency and portable use.


Then, for QRO use, I have the KPA100 and KAT100 in a separate EC2 case.  
I do not have to remove any of the base K2 options to  use the amplifier 
- it just plugs in.  3 cables - RF, control I/O, and power - everything 
takes care of itself from that point. 


The only caveat is that when running high power you have to make sure 
that power is applied to both the K2 and the KPA100 before turning the 
rig on with the front panel switch -  otherwise, the K2 will not detect 
the presence of the amplifier, and will not switch from one to the other 
as needed.   


When the the two units are interconnected, the K2 tuner (KAT2) is 
disabled automatically, and  returns to service when the 2 boxes are 
separated.


When I built the KPA100/KAT100/EC2 combo I decided not to install the 
speaker and wiring in the KPA100 - I left it in the base K2.
