[Elecraft] Amplifier thoughts

[David Bunte]

John -

I used to live in the world you do... but I now live in a neighborhood
where I can't put up a tower, or even a multiband dipole. My 30' Flag Pole
is OK, and, in fact, my neighbors think it is quite nice looking, but in
order to use it on more than the one band where its unmatched SWR is less
than 3:1, I must use a tuner.

I don't expect to be in the market for an amp that is more capable than my
KPA500, but my guess is that an optional, internal tuner capable of
handling 1500 watts into a 3:1 or lower SWR, would suite quite a few
potential users quite well. That way, someone like you, who does not need a
tuner at all could opt to not order that option.

If Elecraft chooses to market an external tuner capable of handling 1500
watts into a 10:1 SWR, then I hope it is one that could be placed out at
the antenna, and controlled remotely. For some folks, putting such a tuner
in the shack, but out of sight would be equally appealing.
