The lingo does sometimes get in the way of things doesn’t it. Don’t be shy here. There are a lot of people here who will try to answer your questions and help you.
Carrier current (CC) AM radio is a system which the FCC rules permit for campus operation. Instead of broadcasting from an antenna as you will do with your SSTRAN, CC systems use building power lines and branch circuits to distribute the signal. The transmitter output is coupled to the plain old 120 volt AC line. The good news is that you can get really good signals inside the building, but the bad news is that power transformers block the signal. This makes covering large or multiple buildings complicated, either requiring multiple transmitters or networks which couple the signal across the transformers (dangerous and expensive). Don’t try this with your transmitter!
In my story in a previous post I mentioned we used leased non switched private phone lines. Back then campuses were not wired for a phone to every room nor did they have their own signal circuits which are so common today. Amost all of our engineering budget, which came from student fees, went to pay for these lines. That is why we built our own transmitters.
Based on your situation at campus as I understand it, CC is not the way to go. I would expect that with a good antenna you can cover your campus with a broadcast part15 legal signal. Start there and see if you are really interested in going further. You will learn a lot by using your transmitter at your home. I predict the first thing you will want to do is extend your range. That’s where the learning begins. Don’t give up because the range you get with a piece of wire antenna is not much. It can be a lot better, you just need to do your research and build a good antenna.
Your experiences and technical knowledge gained if you do this will make a great technical report or term paper.
Keep us posted on your progress.
