This morning I turned on K3 #250 and got a ERR AT3 msg which was strange as when I shut down the radio yesterday, everything was fine. I rarely use the ATU as I have a Steppir beam and inverted L which I run thru an external tuner. I started troubleshooting and went thru the following sequences: After seeing the ERR AT3, I check the config, it was in BYP. ATU Tune- No ATU Config-ATU to auto ATU Tune-No ATU Power-OFF/ON No msg this time ATU tune- ERR LPF ATU tune-ERR IO3 ATU tune-ERR IF1 ATU tune-ERR xv3 ATU tune-AT3 ATU tune-ERR PA1 ATU tine- ERR BP3
Xmit/Tune- 12 w max (KPA100 installed) SWR shows 1.8 on K3 display, LP Pan shows 10.6w and SWR of 1.15 (on exact Steppir freq of 14.050) Same with ATU in BYP or Auto KPA3 in nor Any ideas/suggestions 73 Tom CX7TT ______________________________________________________________ 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
