I have the GAP Hear It on my K3 and in the car. I have the Clear Speech on my boat with a Icom M802. I find they reduce substantially the background noise. It is particularly helpful in the car and on the boat but I also love it in my shack.

I also listen with the SGC ADSP2 speaker, but I do not find it very useful 
with actual QSO's.

How do you get around the relearn time of the DSP speaker when switching 
from transmit to receive?

Keith,
I have been using a Clear Speech AND an SGC ADSP simultaneously with a fixed
K3 at my home base for several years. Basically, I leave it on 'ALL THE
TIME'.  It reduces 'ear fatigue' from extraneous noise and makes the whole
experience inviting to have long casual 'rag chews' even between continents.
Whenever I turn off the extra signal processing to reset the K3 settings to
best performance, I inevitably turn it back on again, because the difference
is so dramatic.  Strong signals sound like local FM and weak signals are
sometimes readable with the outboard DSP, while impossible without it.

Good luck on whatever you decide to do.

I have used the Gap "Hear It" and SGC ADSP2 speakers, which are very
similar, and they have their advantages.  I prefer the SGC because of it's
ease of switching between 0db, -13db or -26db noise reduction with a single
switch.

I use the SGC on 6M, when I want to monitor 50.125 USB continuously.  I put
it in the -26dB mode and all the static is gone, so I just wait for voices
to show up.  Unfortunately it makes everything sound like water dripping,
which can be a little annoying.  The GAP is either on or off, and you are
constaly messing with the switches on the back of it to change the level.

Generally the DSP speakers have a slight delay, which can be a problem.
Every time you switch from transmit to receive, the DSP speaker has to
relearn its parameters, so the first 1/2 second or so is without DSP.  It is
amazing how often this is the other call you are trying to pick out, which
is obliterated by the initial switch-over noise.

I have a K3, and have not found it's DSP to be particulary useful.  Usually
by the time I need to use the NR on the K3, the signal I am listening to is
too far gone for it to really help much.

Is anyone using the West Mountain Clear Speech Noise Reduction Speaker
with their K3? If so, how do you like and what does it do for you that
the K3 does not?

Thanks,
