[Elecraft] K3 - using Clear Speech Speaker

[KB9WMJ at wi.rr.com]

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,
