Eric, That's easy, #1 requirement should be spectral purity at full smoke. So simply take the features and functions of the KPA500 and increase output to 1500W PEP. I'd not like to see Elecraft waste their time with an Spurious/IMD spec that only just pass the FCC requirements, it's about time someone showed leadership here. At the very least I'd expect to see Spurious emissions 60dB (or more) below PEP and IMD 30dB (or more) below PEP across all bands, I'll admit this is not easy to do from 1.8-50MHz but it's also not impossible. This is the minimum commercial spec for 1kW HF gear here in VK already, for inspiration Codan 3062 or LINEARamp Gemini. However it's not easy especially since the FCC ties your hands behind your backs in terms of gain from the get go.
The nice to haves (wish list) would be; - Four antenna output with an internal tuner that could flatten antennas that creep up towards 3:1 at the band edges (ala alpha 9500 series) - Limit the weight of the KPA1500 to the same as the KPA500 is now (preferably lighter) so switchmode PSU's this time please. - Make allowances for those countries that aren't limited to FCC 13dB gain, we'd be happy with just 16dB (*30-40W grin*) and let us pocket the IMD/Spurious improvements If Elecraft were to make such an amp with this sort of spectral purity I'd be inclined to complete the necessary paperwork for a high power variation on my license here in VK and purchase an amp. I've toyed with the Gemini Amp a couple of times but the integration of the KPA500 eventually tipped the balance. Then all we've got to do is get more people pointing their beams at us during DXpeditions and Contests and we'd be set. 73 Matthew VK5ZM On 18 March 2017 at 03:36, Eric Swartz - WA6HHQ, Elecraft <e...@elecraft.com > wrote: > Interesting discussion. > > Folks, if we did introduce a 1500 W solid state amp similar to our KPA500 > in operation, what features etc would be important? > > 73, > Eric > /elecraft.com/ > > > > ______________________________________________________________ > 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 vk...@bistre.net > ______________________________________________________________ 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
