David,
This is the first thing I'd try. I have much success using stubs
to eliminate problems such as yours. However, it won't help much in
the case of common mode problems which yours may very well be.
Shielding and grounding may be your best solution in that case.
I once had a Heathkit freq counter that picked up our FM
transmitter when connected to anything. A 1/4 wave open stub and tee
at the input cured the problem. I've also used them on FM receivers at
the station to knock down our signal enough to listen to other stations.
An open stub at the FM station's frequency hooked to your 900
receiver will add some reactance to the line but that should not be
too much of a problem unless it comes out as an even multiple of a
half wavelength at your 900 freq.
