K3 - ClearSpeech filters

[Bill Clarke]

Is anyone using the West Mountain ClearSpeech filter with their K3? How
does it do with SSB white noise elimination (the constant background his
of the receiver when not actually hearing a signal)?

Thanks,

Bill W2BLC

I use the ClearSpeech speaker in my mobile operation. Same DSP, just adds an amplified speaker.  It is a good addition for mobile but would not recommend it for base operation. The DSP seems to add its own noise.

I suspect you have other noise issues if you are distracted by noise on the K3 in routine operation. I don't find mine noisy.
What is your setup; antenna, grounding, radio settings, etc?

Bill I have a Gap Hear It and a Clear speech both and you have a better
answer in your K3 just use your NR noise reduction. You can dial in exactly
what you need or use the RF/SQL button whichever one you like I use the NR
when I think I have to eliminate the "white noise".

Bill . . .

Neither the K3 nor the KX3 need any external Noise Reduction hardwareat
all, especially when their other receiving tools are brought to bear
along with the NR circuit.

However, I do use the West Mountain ClearSpeech external audio filter
(not to be confused with an I.F. filter) in conjunction with a Yaesu
FT-897D.  This radio (along with many others) benefits greatly from the
ClearSpeech due to the poor performance of the radio's DSP notch filter
and slightly less poor NR.  The adjustable threshold of the West
Mountain version is a distinct plus when compared with the original
Am-Com ClearSpeech which was not adjustableat all.

White noise is the oneparameter that all Noise Reduction circuits
accomplishbest, in my opinion, and the ClearSpeech does it very well.
