My theory on the "Peculiar behavior" issue: I have seen this problem several times before and finally decided it's an issue of interrupted "handshaking" between the K3 and KPA500. Seems that all communicating digital devices go through and introduction to confirm communication before they get down to business. My solution is to power on the K3, -wait till the banner has cleared and then hit the KPA500 front panel ON button. -Wait till the "KPA500 On" banner has cleared and then switch from Standby to Operate. When I have taken the few extra seconds to all the handshaking to complete, I don't recall ever seeing a failure of the KPA500 to deliver full power.

I just turned on the K3/KPA500/P3 as usual (KPA500 is OPER, not Standby) and listened to the band for awhile. I heard a strong station calling on 12 meters SSB from Scotland and gave him a call and noticed only the K3 was putting out power (probably 20 or so watts, the low drive I usually use to drive the KPA500). He answered me and I then came back to him on the OVER, but now, the K3/KPA500 was putting out 400-450 watts as normal -- ______________________________________________________________ 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
