[Elecraft] AF1 filter

[Terry Wilkinson]

Gary:

I've had the AF1 audio filter for several months now, using it with my trusty ol' 
ICOM 735, and am very happy with it. I operate mainly CW (haven't tried it 
with SSB). It enables me to hear many a weak signal that would otherwise 
be buried in noise. Only negative (for me) is that it didn't come with an 
enclosure, but then an enterprising ham (hmm - forgot his name already, but 
he's on this list) began offering a very nice enclosure, so I bought one. Very 
nice result!

Does anyone have this filter and if so, what are your impressions of it? 
I need a good audio filter especially when listening to SSB.  The pitch of
the noise is fatiguing to me.  I don't want to install the internal audio
filter since I will be using this with other rigs.

Thanks,
