Hello all. I have a cobra 138xlr. The radio has a relay in it. I was wanting to install talkback in it and cant seem to figure it out. I have tried the traditional ways, resistor across the pa and ext. speaker, grounding speaker, etc. Please help.

You need a resistor with a 10uf cap in series with it connected across 2 of the points on the relay. If you cant find the points, I will see if I can dig up a schematic.

i will try and let you know. Thanks a lot

That got it. Thanks a whole lot
