[Elecraft] (K3) KPA-250 (sort of)

[Edward R. Cole]

Hey, all that were wondering about the HF amplifier kit I obtained 
over a year ago - I finally built it!  It uses two MRF-422 for 300w 
output with 20w drive.  Well, the K3/10 will not provide that.  I do 
get 15w output (uncalibrated RF) with my K3/10.

The amp kit is distributed by Communications Concepts, Inc. and the 
model is EB27A.  I am getting 270w out on 20/15m, 240w on 
10m.  Output drops as frequency drops but getting 170-190w on 
40/80m.  Full data on;

I'll have photos up in a day or so.

I'm wiring up a relay to provide TR bypass in receive so may be heard 
soon on the Elecraft Net.
