As I recall Eric stating when they first were developing the KPA800/1500 kits that some portions (high voltage boards) would be pre-assembled for product liability/safety considerations. There probably are a few KPA800/1500 beta amps existing somewhere since I believe they were doing some early field testing back in 2006 or so. In 2005, Eric had a working prototype of the KPA800 in his room at the Holiday Inn (QRP hotel - kind of ironic). I believe they had a KPA800 and KPA1500 at the Hamvention in 2006. And in 2007, the K3 took centerstage. Time flies I guess. Doesn't seem like it was almost 4 years ago that the amps were shown at Dayton.
Myself, I have a K3 driving a PW-1 using a Microham MKII interface to control PW-1 frequency/bandswitching, etc. John K8WDN K3 #157 -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of WW2PT Sent: Thursday, February 11, 2010 2:52 PM To: Elecraft Reflector Subject: Re: [Elecraft] Elecraft Amps Since we're dreaming, how about a base model kit (500W) with the option to add up to two additional 500W PA modules via a power combiner circuit. This would allow people to configure it to their needs and/or budget and it would meet Phil's "something new" requirement. Optional: auto-tuner, optional interface (remote band switching, antenna management, SO2R operation, RS232 control, etc.). Offer a fully assembled version for those with Instant Gratification Syndrome, and everyone's happy! An added benefit would be fault tolerance; the amp could continue to operate at reduced power in the event of failure of an individual PA module -- just pop out the damaged module and repair/replace it. de WW2PT ______________________________________________________________ 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 ______________________________________________________________ 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
