The ATU blinks the MODE LED when a tune has been started, but not enough RF is arriving from the exciter to proceed. It's waiting for about 20 watts from your exciter. If you want to cancel the tune, tap TUNE again.
Don't use both the K3 internal ATU and the KAT500 ATU together. One or the other should be bypassed. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Clay Autery Sent: Tuesday, August 8, 2017 09:02 To: Elecraft Reflector <[email protected]> Subject: [Elecraft] KAT500 - Blinking Mode Light Situation: Tuner inline between K3s and known good dummy load. 1) Tuner off - K3s tunes 1:1 instantly 2) Tuner on in bypass - K3s tunes 1:1 instantly 3) Tuner on, and in Manual OR Auto Mode, tuner clicks and then Mode light starts blinking. All components in signal path obviously AND tested known good. Any ideas where to start troubleshooting the malfunction? -- ______________________ Clay Autery, KY5G ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
