[Elecraft] amplifier keying

[Samir Popaja]

If I want to drive "RM HLA 300V Professional HF Linear Amplifier",

do I need something more to basic K2?

William (Bill?):

Contrary to what some have replied, you DO NOT have to have the 
KPA100 in order to drive an external amp to anywhere from 150W-600W 
output (depending upon your amp). The K2 will drive most amps pretty 
well even with the 15W available from the 'basic' rig. Of course, if 
you do want full output from your amp, them the KPA100 will be the 
better choice of driver. In which case you WILL NOT require the 
device suggested below! The AMPKEYKIT (below) is only required if you 
have the bare bones K2... the KPA100 and the K60XV (60M converter) 
option both include MOSFET drivers capable of keying external amps.

Yes, many are...

See:  http://www.n0ss/net/k2_t-r_rly_drvr.pdf

The link includes complete documentation for the addition of this K2 
(Basic) External T-R Relay Key Kit.

This link is also available on the Elecraft web site at:

   http://www.elecraft.com/order_form_parts.htm#

drop down to K2 PARTS AND MOD KITS, and then you'll find it at the 
bottom of that specific listing.
