Talk:K3 Roofing Filters

From Zerobeat

Is there a typo on the shape factor of the 2.7 kHz 5-pole filter? It says 2.9, which is almost the same as the 500 Hz 5-pole filter (3.1). I would expect the wider filter to do much better than that. Where did the info first come from? - Al N1AL

I'm pretty sure Barry N1EU found that somewhere, he's the one to ask. - Don wb8yqj
