Last April there was a thread started by Lyle in reply to a post by Dave, AB7E, about programming the audio mixer in the K3 via external commands. Based on what Marcus, HB9BRJ, discovered about the command structure I have mapped the complete set of mixer commands as follows:
Main=main receiver audio; Sub=sub-receiver audio; L=left earphone; R=right earphone !bec3; Main LR default main receiver setting !bed1; Main L, Sub R default sub-receiver setting !bed3; Main LR, Sub R most useful for split and SO2V operation !becb; Main LR, Sub L alternate preference of previous command !bed8; Sub LR !bed9; Sub LR, Main L !beda; Sub LR, Main R !bedb; Main LR, Sub LR I have programmed eight of the command tester macros in the Elecraft K3 Utility with these commands so I can control the mixer on the fly. The Main/Sub balance can be controlled with the outer (Sub) volume control once the proper CONFIG MENU setting is chosen (SUB AF set to BALANCE). To quote Lyle "Be sure SPKRS+PH is OFF, or SPKRS=2, with these commands." This setup is very convenient except that the commands are not sticky. If you turn the sub-receiver off and back on or power down and back up then you have to reenter the command. While most of the commands are not very useful to me the one thing I would like to have under control is the default value for the audio mixer when the sub-receiver is turned on. Also if an external program (such as N1MM) sends a macro to set the audio mixer then it would be preferable to have the setting not change unless another macro was sent to cancel the previous choice. I have heard that this is not the case at the present but I haven't tested it myself. I know that all of this can be done with an external audio mixing board. In my opinion that solution is a very inefficient use of resources, which are already available in the K3. Lyle would you please put the default audio mixer configuration choice on the DSP firmware development list if it isn't already? 73 Gary, N7IR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
