Jorge,

I find that the 250 Hz filter helps a lot when there are strong signals 
very close to a weak station. I bought one a year or so ago to try, and 
quickly bought two more for each RX (I have one radio with a sub-RX). I 
recently bought a third K3 with one RX and a 400 Hz filter. I plan to 
add a 250 Hz filter to it as well.
