Tim in Bovey’s situation sounds like a very lucky one, given the line of sight.
Neil has posted in the past about infra-red or L.E.D. point-to-point links for line-of-sight solutions.
I would think AM would be a last choice for making a link.
Probably the Decade FM Transmitter would be excellent, but also to mention the Ramsey 25B FM which has an RF output adjustment that goes above typical levels to overcome obstacles like walls and windows. It’s a good kit.
One guy I know uses 49MHz for S.T.L. work.
Hey, and maybe the cable company could enable an upstream solution so you could feed an “out-of-band” signal into your cable for demodulation over at their location.
