I believe the Elecraft gang are hard at work on the KXPA100 for the
KX3 (kinda think it will be ready for Dayton -?). This amp will work
with any 5-10w radio, including the K3/10.
I build one of the CCI kits; the EB27A which provides 270w on 20m
with 12w from either the KX3 or K3. I have used it several times
checking into the Elecraft SSB Net.

I am starting on the AN762 kit (5w/140w) and will have it at Dayton,
if anyone is interested.

Hi Giff K1GAH,
I am in progress of building my own amp according to the Motorola EB-104
application note;
www.ab4oj.com/dl/eb104.pdf
5-10W in, about 600W out depending on your DC supply, all-transistor-amp
using four MRF-150 power FET's. Remember to add a low-pass filter after
the amp.
Communication Concepts in OH sells parts and bits for this construction,
in case you want to hit the ground running.

I cannot tell you about the performance yet since I am still weeks from
the first smoke test, hi-hi.
