I'm now wondering about changing to the 200 filters 5 pole or 250 8 pole (I'm adding the new synth, when the backorder is fulfilled). An edge is an edge but I suspect the 3 db is a rather bare edge.
I started with 400 Hz, then added 250 Hz. I've defined the 400 Hz filter as 450 Hz (so that it switches in at 450 Hz) and the 250 Hz filter as 350 Hz. Both are 8 pole filters. I find that I nearly always have the IF set to 200-250 Hz for CW, and 400 Hz for RTTY. In other words, I rarely use the 400 Hz filter.
It should be noted that the 250 Hz filter actually measures closer to 325-350 Hz. Since they're the same price, I'd buy the 250 Hz filter if I was going to buy one at all.
