You could try running some copper wire for an am antenna. it's simple. lots of diagrams on how to do it. "long wire am radio antenna"

it's just a line of 12 gauge copper wire, with insulators.
You should be able to get CJOB where you are.... worth a try.
Also, maybe try the car radio, they seem to be better than a tabletop radio for reception.
If it's it's hilly where you are, that reduces reception.
