[quote=radio8z]You ask a good question and you are going to receive a lot of answers which are just opinions.
Here’s mine:
First, are we talking about AM or FM. It may not matter since the part 15 rules allow for operation on both bands based on a maximum field strength at a specified distance from the INTENTIONAL RADIATOR.

I am talking AM and looking at possibilities as covering a certain area whether it be a path a mile or two long, or perhaps much further if someone had the money and the man power to bury the wire several miles along a road.
This could mean anyone driving along within 20 feet of the road would pickup the signal. I use this as a possibility as the drive in theater concept as a example.
How about a buried wire along a county road, a buried wire along a pathway, a buried wire from your property to throughout your subdivision or neighborhood ( assuming if you got permission from all concerned).
So how much power would it take to cover a mile or two using buried wire? 100 milliwatts? Or several watts? If a college campus is using electrical lines to transmit a signal within the building.
Would not then a buried wire work for quite a long distance too along the path of the wire? And the signal should be steady along the path of the wire which would make this even more ideal for covering a couple of acres or miles with no fading or interference.
Now for the questions…
So is it legal?
How much power would be involved?
Is one restricted to “leaky coax”?
Can one use a buried single insulated wire instead?
Is this now a carrier current station?
A part 15 station?
Would this be less expensive than several transmitters?
I’ll add this in here, this would not be for everyone. But it could be yet another option one could consider without having to buy extra transmitters and trying to keep them all synchronized. If this legal, it is definately worth experimenting with.
