Radio Systems has CC Transmitter/CouplerThis will be of interest to Jim Henry and others... Radio Systems has a carrier current transmitter and coupler, perhaps the only source of such equipment in the U.S. This transmitter page contains links to the CP-15 Coupler and manuals, etc. TR-6000 TransmitterThere is a Greek CC transmitter proven by Tha Dood in West Virginia who has had one running for a few years. It runs 0-20 Watts, and I'll have the link for you in the near future.

Radio Systems has sold the rights to the TH, iAM, TR-6000 and CP-15 coupler to Information Station Specialists.
as far as I know RS no longer sells or services those products even though the pages are still up on their site.

Tracing the TrailFollowing Part15 Engineer's tip here is ISS (Information Station Specialists): ISS WebsiteThe same TR-6000 transmitter is here, but I find no mention of the CP-15 Coupler or carrier current. Bill Baker is the top guy to ask, and he was guest on a LPH about TIS. Hope we can add better information to this thread.

Notice that you can't get the talking house transmitter outside the US. Since it isn't approved for use anywhere else that's no big deal but that's a shame because it's a whole lot more affordable than the others but if you want to go AM in Canada you are stuck with the $700 one. One choice.

Smart To Say
Mister Hills says: "If one has "one choice," that's really not a choice at all."
The ALPB is the best choice!

Greek Transmitter Well RecommendedFor several years Tha Dood in Poca West Virginia has been running carrier current with a Greek made transmitter and experienced no down time and perfect service! Of course you still need an American made RF Coupler to match between the transmitter and the power lines, but with luck either Radio Systems or I.S.S. (see previous posts) can solve this need. The Greek Transmitter Being Talked AboutCarl Blare is thinking about getting one of these, and if he does he'll let us know.

Yes I saw that Greek transmitter on ebay for $500. Does anyone now the cost of the TR-6000 mtr and the CP-15 coupler? Radio Systems does not price them on their web site. Radio Systems has CC Transmitter/CouplerThis will be of interest to Jim Henry and others... Radio Systems has a carrier current transmitter and coupler, perhaps the only source of such equipment in the U.S. This transmitter page contains links to the CP-15 Coupler and manuals, etc. TR-6000 TransmitterThere is a Greek CC transmitter proven by Tha Dood in West Virginia who has had one running for a few years.

Jim Henry question: "Does anyone now the cost of the TR-6000 mtr and the CP-15 coupler?"
A few years ago I got a quote. They asked $2,500.00 for the TR-6000 and around $500 for the CP-15.
The new owner, which appears to be I.S.S. might have different prices... the main man there, Bob Baker, is a friend to Bob Felmly and was a guest on a Low Power Hour.

Carl, Thanks. Right now I will first see how well I do by enhancing my ground radial system before I consider purchasing a carrier current system.

If the price isn't listed you probably can't afford it
Though I see that Carl has posted an estimate, and it's in the commercial pricing range for the equipment, similar to what LPB used to charge for their school and theater transmitters. LPB cost less, but in today's money it's probably about the same for commercial gear 25 years later.
I've seen the info on that Greek-made transmitter, The FOX, but can't find any user reviews on it on line. There's another transmitter that's 10 watts like the Radio Systems, it comes in a yellow cabinet, and with the color scheme it looks like Civil Defense equipment from the cold war years. Someone sent me a photo, and it looked cool, but I haven't been able to find it again. I think it was also a European model.
You could check with high schools and colleges in your area to see if they have carrier current gear that they're not using, drive-in theaters too. Many schools now have gone on to online broadcasting and don't want to maintain their local AM systems, so they sit idle. Auction and trade sites have older LPB and Radio Systems gear sometimes.
Old gear isn't always perfect though, it can be a hassle for the hobbyist to repair, set up on the proper frequency and use. You want to find a technician who knows the old stuff, since the companies are out of business and there are no service centers for it now. Get past that, and it's quality built, and I especially like LPB's solid state transmitters and coupler.

$3k for the TR-6000 $595 for the CP-15.
