Thx, but that's not the ones I have. I have the SR3000 HRS, and it uses a std. stranded copper wire. And no plug inside
Also the wire comes out from the top of the case, not the side.
I just couldn't figure out the circuitry board on this one! It just looks odd! I've replaced many antennas before on FM system, no problem there. Use a small solder iron, very small tips etc.
I'll see if I can post some pics to explain...
