I just discovered the idea of carrier current for AM broadcasting. This is very interesting. I didn't know that you are allowed to transmit an AM station directly into power lines. This seems like it would be fun. Building a big AM antenna is hard, but if you could have the AM signal in the power lines, driving down the road next to the power lines and hearing the signal much farther than with a traditional antenna is exciting.
Unfortunately, most of the info on this subject is outdated and always seems to reference using an LPB (low power broadcasting company) coupler. This company no longer exists. I was able to find one independent diagram however:
Does this seem like a viable circuit? I don't know what that 0.5 AMP part is though (don't know what electrical symbol that is). It's also kind of pixelated. Can anyone comment on those resistors 5.x or something? Also, do you think this could be built to handle a 100W AM transmitter? This seems really sketchy, but that makes it even more fun
