You can do this. You need to have the firebox mixer program running and you need to turn up the software pot in that program for ch 2. The firebox does not like DC bias on its input so if your thinking of just taking some speaker output from your keyer and blasting that into the firebox, think again. I used an audio transformer in the output of the keyer to accomplish this feat using a logikey keyer.
I tried to use a non polarized DC blocking cap but found that solution to be inadequate. The primary was connected to the output of the keyer chip, the secondary went to a stereo self canceling jack. the canceled side went to the speaker and the plug side went to the firebox. I think I used a 1:1 transformer but I can't remember for sure. I got the transformer from Radio Shack. 73 W9OY __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
