Hi Richard, It's true that there are lower-cost alternatives to the KXPA100, including backpack-style 30-50 W amps. The latter would be a good choice if you're looking for minimum size and weight in an amp.
Many competing 100-W amps don't cover 160-6 meters, or don't make it to 100 W on 6 meters. Many have poor IMD performance on some bands (we bought one of each and tested them in our lab; some were truly awful). None of them offer a companion internal ATU. We were very aggressive in our efforts to minimize cost, but we had some non-negotiable objectives: 160-6 meter coverage at full power; individual low-pass filters on every band to optimize for low transmit IMD; extensive monitoring circuitry to ensure safe operation; a large heatsink to eliminate the need for fans; and full integration with the KX3, including automatic control of the ATU option and its dual antenna jacks. We included a carrying handle and mounting points for mobile installation--as far as I know, these are unique to the KXPA100. The KXPA100 isn't for everyone, but it does meet our stringent performance and functional objectives. 73, Wayne N6KR On Jun 18, 2013, at 11:27 AM, Richard Thorpe <[email protected]> wrote: > QRP is looking better…. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
