Nate replies: That shouldn't be too hard, I found two schematics for carrier current coupled intercoms, and the circuits are both simple, and similar too. The line cord comes in, goes through two choke coils, then into a power transformer for the unit.
There's a final transistor connected to an outpup coil, and it's tunable, guessing it has a screwable coil like a receiver IF coil. The secondary of the coil the RF output, goes through a capacitor to the junction between one side of the incoming line cord and chokes.
That seems to show that if you wound a coil and and then a secondary over it with fewer turns as shown, connecting the primary across the Talkinghous oueput, you could connect the secondary to a line cord through capacitors the same as the intercom, but all external to the TH.
Rock95Seven, I've had the same effect myself, running the Talking House inside, and the signal on the power lines goes alot farther than the through the air signal. Under the lines it can go a long way and finally it fades out. Lower frequencies seem to do better on the line, they last longer, but upper band is almost as good, it seems the signal has more energy at first and then dropps off faster though.
Funny how so many of the experimenters here trying this stuff are pretty big Rock heads, maybe all of this prog and album rock has expanded our minds.
Yup I'd like to see it tried and maybe it could work really nice here. Got to love it.
Rock Heads are driven by a strong need to bring rock to every empty frequency on the dial and every un-filled ear.

Or maybe it was those "extra carricular" activities after school and on the weekends, or maybe that was an illusion.
