[Elecraft] KPA 500 or SPE EXPERT 1K-FA

[W4GRJ]

I am sure the KPA 500 will be an outstanding amplifier however, there is an
existing alternative with advantages (besides 1kw) over the KPA 500. Namely
a built in antenna tuner in addition to power supply. The spec says it tunes
3:1 but mine will match 5.5:1 automatically and close to 10:1 manual mode.
Very compact  (W 11.02", H 5.51", D 12.60") see all the specs

However, the 1K-FA is not suitable for outdoor application.
