Hi Franco, Fully agree Arie's comments, I'm not using an auto Amp. only a manual one with a Russian tetrode, and only checked on the K3 that the time delay corresponds to the amp specs and that's all. With my K3-100, most of the time I'm driving it with 12W and the output with my amp is ±350W thats cover most of my applications. At 13W it engage the KPA100 for higher power needs. Just set the K3 to the power level you want to use without going over the specs of your equipment. Bst 73's Philippe A65BI

Just gently set the power of the trx yourself to drive the PA to the right powerlevel and go. 73 Arie PA3A -----Oorspronkelijk bericht----- Hello I use the Expert 1K-FA with K3 full power and ALC , but i think i have two issue. When i use K3 full power ( with Expert full power ) the rig output is not stable but fluctuates around 15 watt and more or less of 5 watt , and of course the output of Expert varies consequently . When i use Expert half power i have not issue , the input and output power are stable. Another issue is that when i put the Expert in STBY , the K3 output power does not return instantly at 100 w , but slowly in 3 - 4 seconds. When i not use the ALC i have not issue. Thank you Franco I6QFZ ______________________________________________________________ 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 ______________________________________________________________ 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
