New Amplifiers ...

I know that information on the new Elecraft amplifiers is scarce, but does
anyone know if the K2 (15W) will be able to provide sufficient drive or will the KPA 100 be required? I'm trying to plan my future purchases ...

Hi
I have no information on this but I think there is a specification from the FCC that any external HF band amplifier must require at least 50 watts of drive for full output. This is to keep the CB'ers from using the amps with the 4 watt CB rigs. There was even a lot of discussion about the KPA100 but it was approved because it can only driven with a K2 because of the tightly integrated control structure. It is really considered a part of the K2 not an external amp. I would expect the power amps to require the KPA100 although Elecraft has a way of surprising us in good ways when new products come out. There always seems to be more performance than you expect when final product is announced.

Dave, The K2 by itself cannot legally drive an amplifier to full power; the rule states that at least 50 watts of drive must be required. That said, you'd still get hundreds of watts out :) By the way, I replied to you twice on this subject already (when you e-mailed me directly). Looks like there's problem problem at either your server or mine. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

How about a version for all of us not in the USA that are not encumbered by
FCC regulations? Take the K2's 10 watt PEP or 15 Watt CW output and generate somewhere in the neighborhood of 400 watts PEP or CW. Perhaps a KPA400 would solve the FCC problem. And of course we would need a matching KAT400, BL4,...

In previous comments here on the reflector, Wayne said that the new amps
will develop several hundred watts output when driven by a K2 at 10 watts or so and: "...will accept band change data from most popular transceivers, as well as computers, or via complete manual controls on the front panel. It also has a large, easy-to-read, 20-character alphanumeric LED display that shows what rig you're using (A or B), the antenna (complete with names, e.g. "YAGI"), PA temperature, and PA current drain. There's a full menu system, etc., etc. Details pending!" Ron AC7AC -----Original Message----- How about a version for all of us not in the USA that are not encumbered by FCC regulations?

Yes, but with all those features and SO2R, and the capability of 1 or 2 KW,
the price will be high. I'd love to see a 400 watt or so integrated amp for the basic K2 with no frills. A KPA400 option rather than a KPA100. A separate box would be okay, like some have done with the KPA100 in an EC2 case, but still with full control from the K2.

Something like that just might just get me to sell my 200W Yaesu FT-1000MP
Mark V. I love my K2 but I use the FT-1000 when I need more power. A 400 watt K2 would do it all. Have you ever looked inside an FT-1000 or other similar radio. I wouldn't know where to begin to repair one. It's difficult just seeing the components. A K2 and a 400 watt amp that you could build and repair. What could be better.

First off, I didn't mean to imply that Elecraft shouldn't continue on their
path to the big amplifiers that they are building. Sorry if anyone had that impression. My hope was that a lower priced, lower power version would also become available. I can't help but wonder if some of the technology in the new amps could result in such an amplifier as I propose. Just like the K1 uses a lot of the design and technology of the K2, but in a simpler context. To get a solid state amp of kilowatt proportions, it must have at least a few individual power amplifiers combined into one output. My hope was that perhaps one or two of these individual power amps could form the basis of a KPA400. I also didn't realize that the FCC restricted manufacturer of amplifiers with certain power specifications, I thought that they merely resticted the sale or importation of such devices and it would be okay for Elecraft to build an amplifier for export only. I have since been educated. Therefore a KPA400 option looks like the most practical option. 73, Darrell VA7TO K2 #5093O on February 4, 2006 08:33 am, Darrell Bellerive wrote: > How about a version for all of us not in the USA that are not encumbered by > FCC regulations? > > Take the K2's 10 watt PEP or 15 Watt CW output and generate somewhere in > the neighborhood of 400 watts PEP or CW.

Let's see:
K2 + KPA400 vs. K2 + KPA100 + 800 watt amplifier. What would be the $/watt? You're right 800 watts is a very nice power level, but there have been a few transceivers that have featured 200 to 400 watts output like the Yaesu FTdx-400 or some versions of the FT-1000. Niche market to be sure.

What a refreshing thing.....although the AFA(amateurs for aligators) might object to not being able to run high power.
