"It works very well. The op has to set the K3 so that the power is controller per-band. When the KPA is switched to OPmode, it sends a message to the K3. The K3 then switches to the amplifier selection for power, which the op has set specifically for the KPA."
Jack, I'd love to see the worst case system timing diagram for that but I know that's not likely. Either the [KPA500 state]>[K3]>[K3 power control] is very fast or the KPA500 does not fault as fast as I though it did. Perhaps both? So, no KPA500 fault, no power spike, and no damage when KPA500 is switched to OPER when K3 is transmitting with 100 W output. I'll have to move that one to the "good as" list from the "better than" list if I even do a write up on my TS-590/Elecraft controller. "Good as Integrated K3/KAT500/KPA500" was a top level system requirement. "Better than" was just nice to have. 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]
