Hi all,I have built an interface for PSK31,SSTV,RTTY and it works brilliantly.The problem I have is that I have it plugged into my microphone socket because it appears that there is no accessory plug in the back of the radio.When it comes to working SSTV and speaking to the operator at the same time I have to unplug the interface and plug in the micro and then the interface again,it's a big hassle.Has anyone wired their interface to the back of their radio and if so what socket did they plug into.I would be very interested to hear because this is so frustating.Thanks for taking the time to read this message.

               Cheers Steve ZL3TS

PS:Happy New Year to all.

Some where I saw a device that would let you plug in 2 mic connections with one cable out for the rig...
I had the same issue with my old FT840. Mobile rigs do not often come with auxilary connections in the back... What I did was open the bottom of my MC-50 base MIC and wire my HB interface cables (audio and PTT) into the appropriate terminals inside the MC-50 base. The PTT and audio functions of the interface were in parallel with the MIC. This worked great for 5 years! I assume you could do the same for even a simple hand-held MIC... Make sure you adjust levels so that the MIC does not pickup your shack audio while you are in the sound card mode.
