[Elecraft] K3 SSB transmit IMD

[Dave Hachadorian]

I'm a little unsure about what the ARRL is saying in their 
evaluation of the K3's transmit IMD. Here's what I THINK 
they are saying:

ARRL's K3/10 measured -23dB worst case. They contacted 
Elecraft about this low reading, and Elecraft told them it 
should be "significantly better" than that, and Elecraft is 
working with ARRL to see why their K3/10 had such a low 
reading.

Elecraft also seems to have made a general recommendation 
for ALL K3's that until the IMD problem is resolved, the low 
power amp should be run at no more than 8 watts on 17 meters 
and higher. ARRL then got ahold of a K3/100 and measured IMD 
at the output of the low power amp, with that amp running 8 
watts, and measured IMD at -27dB.

Am I reading that correctly? So for best IMD, until the 
issue is resolved, the K3 needs to be throttled back on 17 
meters and above? Is that like 80 watts or so on a K3/100?

Thanks.
