[Elecraft] Inrad 1500Hz filter for the K3

[Bob Stonesifer]

Well they are out of stock, so the filter must be pretty good, or at
least popular.
 
I have read nothing but good about this filter, though it seems to be a
bit narrow for SSB, or that is what history tells me.
 
Any bad on this filter?
 
I would actually like to put one in the K3 and also the Mark-V, as they
share a common IF frequency ( 8125 kHz ).
 
Not looking for Hi-FI, just the best blocking that will still give an
intelligible SSB signal.
