Can someone please explain how a "roofing" filter differs from the old
fashioned (band pass) IF filter? Or is it just another name for it?

Bill:
It appears to be just another name for it.
Commercial use of this name implies that a filter is low-pass with an upper cut-off freq. (a roof)
But amateur usage seems to use the "roofing" name as being closer to the "front end" of the RX....
(a roof over the receiver??)


We had a discussion on this many months ago and we'll just adapt to the new interpretation... :-)
