How to attenuate certain FM frequencies?

[g33ky]

Hi you lot. Does anyone know if there is a way to block certain FM frequencies while letting others through? Where I am I have Storeton, Llangollen and Capital Liverpool blasting into my SDR meaning I can't set the gain too high without having receiver overload. I know there are full FM band blockers but thats not what I'm after .

put the rx in a farady cage ,what an option ,or use a band pass filter tunable.

Neither is going to work, Radium - he just wants to eliminate particular specific frequencies.

You need stub filters cut for the frequencies that you need to attenuate. The ARRL handbook shows how to calculate and tweak them.
