[Elecraft] KPA500 - power out question

[Bill]

Thanks to all who answered. I didn't know there was such a perceived 
difference, at the receiving end, between 500 Watts and 850 Watts. I 
have always been under the impression that doubling of power (3 db gain) 
was the least discernible difference and that if you did not, at a 
minimum, double your power - there was really little to be gained.

Also, I am amazed at the reported differences in power - from 350 Watts 
to 600 Watts. That is a rather large disparity.

Thanks,

Bill W2BLC
