Jorge, Have you checked the KPA500 menu to see what the transceiver setting is? It could have changed for some unknown reason. It should be set to K3 for the K3 to change bands on the KPA500. When you say it works fine alone, is the KPA500 changing bands correctly when you change bands on the K3 using the band change button on the K3 not RF sensing?

I had been successfully using my KPA500 with an Icom and a K3 , alternatively with the use of the Key Line interrupter and a separate key line. Suddenly I cannot change bands on theKPA500 or go on Tx, even though the auxiliary cable is well seated and the Key line interrupter is well screwed to the K3 . The kpa500 works fine with the K3 alone, or when I disconnect the auxiliary cable from the K3 ,then I can change bands and use it with the Icom as long as I turn it off and the on again . This happens even when the K3 is off . I have also tried disconnecting the k3s serial cable to the computer and even from the PS , but no luck. Wonder if any one has experienced such a problem. Any ideas? Thank you Jorge HK4CZE ______________________________________________________________ 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]
