"I rode the drive power downward as the power increased to stay below the trip point of 105c."
Was that intended to be "as the temperature increased"? If so, do you have any data that shows PA dissipation is lower at reduced power levels for the KPA1500? For the KPA500 PA dissipation increases as power is reduced and peaks at about half rated output. 73, Andy, k3wyc ______________________________________________________________ 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 Message delivered to [email protected]
