I would like to use N1MM's voice keyer with my TS-480. To control the radio with N1MM is no problem... But how do I get the radio to "play" the WAV files? Do I just connect the computer audio-out in paralell with the mic input on the local RRC? Or is there any smarter way to do it?
Regards,

That's more or less how I do it Adde. I have the usual isolation for the pc and us a relay that switches the mic in line when the ptt is pressed. Works just fine. 73 steve

Thanks... Two more quedtions then... What type of isolation, and where on the PC do you take the PTT signal?

Adde I use a traditional PC interface using optoisolators, but I guess transformers will work just fine too. I define a com port on N1MM to switch the PTT and pick it up from there. The relay in my h/b interface box steers the audio. As I contest on VHF+ I call CQ a lot. As a result my NC relay contacts are connected to the souncard audio and NO to the footswitch (mic) PTT. I do not route my mic audio via the PC soundcard in case the PC fails for some reason.
This is not an elegant solution, but I had the bits in my junkbox, so I made something that worked at the time. It hasn't broken, so I haven't changed it!
With my other radio (also via an RRC) I have used a microham interface, but am having problems with that set up at the moment.
Hope that helps?
