[Elecraft] [KPA500] Low Power Use Cases

[Chris Johnson]

I love my KPA500.  I don't use it enough because of all the low power digital I do.   I was wondering if the quality of my signal would better if I let the KPA500 produce the output even if the wattage is 50 or less watts.   If I drive it with 1 to 5 watts, it produces 10 to 50 watts.   I like the thought of offloading the thermal load of my long JT65 & JT9 duty cycles onto the KPA rather than my main rig which is a Flex 6700.

Does the KPA500 make a much cleaner signal than the built in barefoot amp because its running at such a higher voltage?   I'm not too concerned about power efficiency comparisons, because we know its not more efficient doing it this way. :)

Thx
