Just a follow-up to my question about using the KPA500/KAT500 with a second, older radio. I just finished some more testing and found that when I remove the AUX cable from the back of the KPA and try to put the KPA into TX with the keyline, it stays in RX.
A continuity tester confirms the rig keyline is closing when the rig is in TX, and the KPA shows driver power output, as does the KAT. But, the KPA won't switch to TX and amplify. Is there some other function keeping the KPA in RX even though the AUX cable is disconnected? 73 de Chuck, WS1L [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]
