[Elecraft] K2 external auto tuner and 100 watt amp

[Jim Wiley]

Paul -


Yes, the K2 and the 100-watt amplifier / KAT100 tuner can be used in the 
way you describe.  Order the version of the KAT-100 that is intended to 
be used this way.  The correct model number is KAT100-2.  You will need 
the following items as well:  (1), an EC-2 enclosure  (2) a tilt-bail 
ETS2 (so you can tilt the amp/tuner up at the same angle as the K2) - 
although I preferred less tilt and ordered 2 each ETS15 tilt stands, one 
for the amp, one to replace the one on the K2.   You will want to make 
up a cable for use between the K2 and the amplifier, a cable with 3 
"ends".  One end plugs into the K2, one into the amplifier, and one 
hangs loose as the connecting point for external accessories such as a 
computer for digital modes. 


There are several ways to complete the assembly.  I chose to  leave the 
basic K2 pretty much alone,  so it could be operated as a 10-watt 
portable rig.  I did not install the speaker or shield that came with 
the amp, preferring to leave the speaker in the K2.  This also meant 
that I didn't need to install speaker wiring inside the amplifier/tuner, 
and saved one interconnecting cable.  You may want to do things 
differently.  When assembling the amp and tuner in the EC2, the tuner 
bottom plate becomes the bottom cover of the enclosure, and the 
amplifier heatsink becomes the top cover. 


In my setup, the K2, KSB2, K60RX, KNB2, KDSP2, KBT2, KAT2, and KIO2, and 
speaker reside in the basic K2 box, and the KAT100-2 and the KPA100 
(without the speaker) fit in the other box (the EC-2 enclosure). 


If you have any questions during the assembly, somebody on this 
reflector can help you.  If not myself, then one of the other people 
that hang out here will be available.
