"The Elecraft KPA500 amplifier also works efficiently into a load SWR of 1.5:1"
Any such claim is at best misleading. There may be some 1.5:1 loads that that the KPA500 will be happy with but there are other 1.5:1 loads that it will object to, to the point of giving multiple PA DISS faults. 1.5:1 SWR does not define the load characteristics. A 1.5:1 load could be pure R or it could be a complex impedance. The efficiency, PA dissipation, and risk of fault trip are not defined by the SWR. 73, Andy k3wyc ______________________________________________________________ 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
