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!

K1 - 1800
K2 - 5944
K3 - Oh, probably not!

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,
Gary, N7HTS

Thanks for the input, Terry!  I operate mainly CW also but, I also operate SSB
a little.  I have an Autek Q1-FA audio filter and it works fine but, the K2
doesn't have enough mojo for my external speaker.  I noticed that the AF1 has
a built in amp so I'm hoping that will work.
