amplifier keying

[William Langford]

If I build the K2, how could I key my Ameritron ALS-600 amp?
Is anyone out there driving an amp with their K2?
Thanks

You'll need the K2/100, of course.
Then you key the amp with the PA Key out (RCA Jack)
connection on the rear panel of the KPA100.  Easy.

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.

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.

Hi Group,

I have recently upgraded my amplifier keying with Tom's kit.  In the past,
Elecraft also sold an amp keying kit at US$5 plus postage.  This earlier
version consists of two 2N7000 with similar working principle of Tom's kit.
This kit is now surplus to me. It is a completed kit and ready to be
installed in K2.

If any of you are interested, please email me off the list at
[hidden email]  I shall let you have it at US$4 to cover my ordinary
airmail postage + packing materials from HK to US.

If I want to drive "RM HLA 300V Professional HF Linear Amplifier",
http://www.rmitaly.com/scheda.asp?IDGr=1&cat=19&tipo=188
do I need something more to basic K2?
