I just finished airing LPH #13, and in it K-Rock was talking about an invention he was working on which would enable a hobbyist to simply plug his output into a wall outlet and be on the air via Carrier Current...
What ever became of that project?

The Last I Heard
At the time LPH#13 was recorded K-ROCK was between professional jobs and had time to experiment with carrier current, but very soon after that he was hired by Townsquare Media, a nationwide corporate owner of radio stations.
K-ROCK became the chief engineer of Townsquare AM/FM stations state-wide in Wyoming and it is a very demanding but great job.
I need to make contact to catch up, but meanwhile it's good to see his website is up and running.
He is the ultimate master of carrier current, helped me get mine on the air.

If he ever gets this working I would be most interested. Especially now that 1630 kilohertz is no longer available and I would have to transmit on the lower end of the band which we all know that over the air signals don't do very well on the lower frequencies. However carrier current would just be ideal.

Things To Know About Carrier Current and Sockets
The most efficient carrier current-to-socket coupler would plug into one of those big 3-pin 220-VAC sockets as are used for large air-conditioners, electric stoves and washer-driers.
A carrier current socket coupler feeding only a single 110-VAC outlet would only give about 50% efficiency but would be better than nothing.

Just plugging in is the common way for for non-professionals to do carrier current, when you think about some old push-to-talk intercoms. A radio associate, Tha Dood, has explained to me how they use a frequency in the longwave band with frequency modulation, and can be heard quite a distance there. Those couple the signal in and out through the same plug that goes into the wall.
Sure, with a proper coupler box, and hookup and some RF chokes, you can send the radio signal back up the line, even through the same AC socket that's powering the transmitter itself.

That was what I was thinking of. Especially in an apartment situation this could work nicely. Deltaville VA is small and from what I saw the main power comes in from just down the street from the Deltaville Market. This could be very good for running a good AM station in this town.
Maybe we'll finally have that ability.

It's not really hard, the problem is finding off the shelf parts and pieces you can just plug together and then into the wall to make it work. Some soldering could be involved, but luckily it's all big pieces. I'd recommend doing away with the soldering and just using screw type barrier strips. You'll need at least one strip, a power choke on a donut toroid core, a few capacitors and a power plug and cord. If I have time I can diagram what I did later on, made mine on a piece of wood with a radio loopstick.

Something to Learn FromThis project shows how to build a 2-Watt carrier current tube transmitter. The coupler is part of the diagram. If you built only the coupler it might work with another transmitter. The Project I'm Talking About

That's what I'm barkin' about, the RFCs 3 and 4 are like what I was thinking of, though I'd wind them both side by side on a ferrite toroid. I'd also make it so you can feed either side of the line with signal, or both.
I've seen that schematic before too, seems like a classic rig all around, especially for tube heads. All the tubes would be pretty easy to get, the crystal would be tough though.

Artificial Radio Empire
Is the "Artificial Ground" machine something from the Onion News Network?
I have an artificial audience that I am sure is listening out there somewhere.
On some days I think this forum is artificial.

On some days I think this forum is artificial. The actual product is used to tune reactance out of oh oh, LONG GROUND LEADS. So, could this be used a CC coupler?

Hopes Up Before They Come Down
Druid Hills seemed to say: "The actual product is used to tune reactance out of oh oh, LONG GROUND LEADS."
So, if what you are saying is what I hear you say, this machine will allow us to have long ground leads without incurring the wrath of the Resident Agent Provocateur?

I think he meant that you can use the machine to allow long ground leads and thus make your TX go further. Assuming the FCC is going to drive around like the Google car and check everyone's measured ground lead. Highly unlikely.
Too much paranoia among Hobby Broadcasters which outweighs the concept of reality at times.

TheLegacy lays it out: "Too much paranoia among Hobby Broadcasters which outweighs the concept of reality at times."
Carl laughs. Concept of reality! Ha ha ha. Sure. Who uses that?
