KPA100 as a separate box

[John Wiener]

I read in the KPA 100 manual that it is easy to remove the amp to use  
K2 in QRP mode.  I also, see several amps mounted in separate  
enclosures.

Is it really a quick-change procedure to remove the KPA 100 from the  
K2?  If so, what would be the reason to use a separate enclosure?

Hi

Swapping the top is easy. It requires removing 6 screws and unplugging a few
cables. The only problem is the side screws that thread into the KPA100 tend
to strip out if removed too many times. You can replace them with the larger
screws available for free from Elecraft or just not use them. It does take a
few minutes to do the swap and you need to be careful to plug in the cables
correctly and make sure the cable routing is OK

The reason for mounting separately into an EC2 box is the K2 can remain in
its QRP dress including the battery, KIO2 and KAT2. The KPA100 and perhaps
KAT100 resides in the separate EC2 box. For QRP operation just unplug a BNC
cable from the KAT2 and the 9 pin control cable from the KIO2 and you are
ready to go. When every thing is reconnected the K2 "knows" the KPA100 and
KAT100 are there and sets the KAT2 to bypass as well as enabling the KPA100.
The unplugging takes less than a minute and does not require opening any of
the boxes. Besides the matching separate units look cool in the shack.
