Andy - Yes, there are many reasons to match as well as possible ... depending on many other factors ... so I never argue with that principle. Bob put together a very nice spreadsheet that makes it easy to quickly see what's going on.
One thing I really like about this group is the friendly, helpful participants. I'm probably in 15 different groups, but this is the one I always check first. Thanks! 73 Lyn, W0LEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Andy Durbin Sent: Wednesday, September 22, 2021 5:59 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] KPA1500 Power Level "Would you care to share your KPA500 power measurements at each of those drive levels (and test mode used)?" If you receive this data set be sure you understand that dissipation, heating, and efficiency will be strongly dependent on the complex impedance of the load. I have previously shared test data for my KPA500 but I made no attempt to record drive level and have no data for gain. My measurements were made to explore the influence of output power and loading on PA dissipation. Once you have this data you'll stop believing those who say there is no reason to match to better than 1.5:1. 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 l...@lnainc.com ______________________________________________________________ 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
