I wonder if a magnetic loop antenna might be worth considering? Their most appealing feature is their immunity to electronic noise, but the they are directional with significant nulls which could be directed at the interfering station.

You should find 2 or 3 quite lengthy old threads on this forum, and tons of references via Google about magloops. The commercial magloop made by Wellbrook sells at over £300, and those who have one swear by them. Alternatively, its clone, the "Wellgood", can be built for next to nothing (I built one). One or two people on the forum are pretty keen on them.
