How about a pair of 3CX3000A7's with auto tune, in the K3 form factor? :-) Sent from my iPhone > > I'd like to see the KPA-1500 use dual 1kw LDMOS transistors __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] KPA-1500 features
Is Elecraft seriously considering a KPA-1500 or KPA-2K?

Re: [Elecraft] KPA-1500 features
Eric asked for input on features/characteristics/specifications desired
"if" Elecraft were to embark on such a project. He's gotten a lot of
input. There were a couple of prototypes knocking around at selected
hamfests several years ago. Nothing came of them. There's obviously no
technical/engineering reason that would prevent Elecraft from fielding
something of this nature on the market. The real issue is ... would it
be profitable. Sadly, the math to answer that question is far more
complex than designing it. [:-)
