james, you say "other channels"... Could you elaborate?
Sounds to me like a leaky ch3 or ch4 analogue output from a STB or VCR or similar device, often caused by really crappy cables between devices, or a horribly leaky TV or device. Plastic housings are notorious for this kind of thing.
If it was a leaky cable company run, you'd get more channels spread across that spectrum as opposed to various channels from time to time on a single frequency... :-)
One side effect of cable going digital is it places tougher demands on the systems to use better quality cable, thus reducing "egress", the signal leakage from cable, and likewise, "ingress", signals getting into cable systems.
Taking that radio portable could help sleuth the source.
