Have a Sigtronics 4 place sgi stereo intercom to replace my old sigtronics 2 place in my 182. Planning on starting the work in the next little while. I need wire for the rear jacks. 20 awg 3 conductor twisted shielded ground seems the best, but who sells it? Nothing at spruce...Other options?

20ga is probably more wire than you need. 22ga should be sufficient and is readily available.

There's always Radio Shack, too.

I would use 22/3 Mark.

Perfect the 22 popped right up on spruce's site. Not sure why they only supply a 4 ft length for the rear seats with the kit, wire is relatively cheap.

FWIW, until I had my PS Engineering audio panel installed 4 years ago, which includes their outstanding intercom, I had a 4 place Sigtronics for about 9 years. It worked OK, but by its design, it opened all 4 mics whenever one was triggered--it only had one channel. It also tended to clip speech, not breaking squelch immediately and squelching if the speaker lowered his/her voice a little. It seemed like I was always having to fiddle with the squelch. So there may come a time when you'll want to upgrade to a better intercom; if you do, I can definitely recommend PS Engineering. Meanwhile, I suggest that not plugging in the headsets that aren't being used helps a whole bunch to minimize annoying false triggering of the intercom.

Curious what model you had? I've worked on many sigtronics and had a couple now and have never heard of that. They work great and I really like the sigtronics.

Mark, not sure which one you got, but the 4S has a seperate volume on its case as well as the front. Be sure to try it and make sure it's high enough before mounting it in the panel. It's a can he a bit of a pain to adjust after, depending on where you mount it.

I got the new SCI -4 as a present last Christmas. I sure hope it would be decent. The 80's era one I have still works ok, just only two place.

I haven't any idea what model it was. It was installed in the airplane when I bought it, and only wired to jacks for the front seats. At the first annual after purchase, I asked my IA about getting a 4 place model, and he told me that what I had was a 4 place, only wired for 2 places. So he added some jacks for the back seat. As I said, it seemed to work fine; the PS Engineering intercom is just a whole lot better.
