The KXPA100 blinks a LED while ATU TUNE is in progress. The ATU TUNE needs steady carrier from your KX2. ATU TUNE is done with exciter power, and when it's complete, the amp can be switched in.

The power amp light blinks slowly (not on steady) and while turner tunes, the amp will not go to transmit but shows 25 W output. I am using the KX2-controled connection. My KX2 S# 01749 was new from Elecraft; the KXPA100 S# 1532 was acquired gently? used. 73 Sam, KG9NG ______________________________________________________________ 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]
