[Elecraft] KXPA100 with other QRP rigs...

[Igor Sokolov]

Phil,
With 1 W drive I get around 25-30 W on 15 and 10 m bands and close to 50W on 
20 m band from KXPA100

73, Igor UA9CDC

Yes, but that does not answer my question.  I could have been more clear I 
guess.   I am thinking that this 3.5 to 7 watt range is to achieve 100 watts 
output.  I am asking about, say, 1 watt drive and certainly I expect the 
output to be lower.
