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. 73, Kent K9ZTV On 11/15/2012 8:01 AM, Bill Clarke wrote: > Is anyone using the West Mountain ClearSpeech filter with their K3?
