Thank you Joe. That is a good suggestion. However I have checked and as far as I can tell there is no conflicting PTT actions. I also use DATA A as the recommended mode in the KX3 and do not use VOX. I believe that PTT is either via RigCAT or Hamlib, and no PTT port is provided in the Fldigi configuration. Everything works fine except for that the KX3 refuses to completely unkey on its own.
I unlikely to encounter this problem for long because I have decided to order a USB sound card hub to provide the MacBook Retina with an external sound card with audio input and output. The MacBook Retina is supposed to have external input and output via the single stereo audio port using a 4-ring stereo plug, but in my experience this did not work. Besides using an external sound card makes also sense to avoid spurious signals from the environment. I'll be using the Signalink with my desk radio and keep the little audio hub for the occasional digital with the KX3 from the trail. Much appreciated. 73 Jose VA3PCJ -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-won-t-unkey-properly-tp7599065p7599124.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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]
