Hm, the difference is that not everyone needs a automatic antenna tuner and everyone needs the power supply. If you have one of them external, there are strong arguments for it being the antenna tuner.
We have tuneable antennas, and many other antennas run fine without a tuner. And the options for an antenna tuning unit include automatic tuners, simple manual all-band boxes, and per-band matching networks, as well as intersting things like the fellow (I can't find the URL right now) who switches binary weighted lengths of twin-lead feeder in and out to match his wire to his radio. I suspect that the KPA500 will bootstrap Elecraft into a higher-power amp in the same size box with an external power supply, but that's wild speculation. 73, doug Date: Tue, 20 Apr 2010 09:09:14 -0700 (PDT) From: Mel Farrer <farrerfo...@yahoo.com> I agree, I don't mind an under the counter supply.

It would leave plenty of room for a built In antenna tuner ? ______________________________________________________________ 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
