[Elecraft] Inrad 1500Hz filter for the K3

[K4IA at aol.com]

It is narrow but you slew the passband shift over so the max  
intelligibility matches up with the center of the audio (not necessarily with  the center 
of the filter) and you can copy SSB with a 1.1 khz filter.   Play with it 
you will be amazed.  The intelligible portion of audio is  really quite 
narrow.

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.
