"The ONLY good use of ALC between rig and amp is to protect the amp from a failure in the antenna system. "
The KPA500 doesn't work that way so I'd be surprised if the KPA1500 did. For the KPA500 a badly mismatched load will trip the reflected power fault without making any change to the ALC voltage. I know this because ALC voltage is included in my logger data set and I have several logger records for Fault 09. (It's not that I'm really careless about antenna switching. FL09 was a deliberate test case for evaluating a KPA500 firmware defect.) 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
