[Elecraft] KX3 Noise Reduction Performance

[Ed Ketterer]

All,

The effect of the NR (DSP) feature on my KX3 appears to vary with the band I
am on. On 80m and 40m, NR significantly reduces noise when the preamp is
off, but has little effect when the preamp is on. On 30m and 20m, there
might be a bit more noise reduction provided when the preamp is on, but
again, the effect is much more dramatic when it's off. On 17m and above, I
get very effective noise reduction regardless of whether the preamp is on or
off. It would be nice if the NR feature provided significant noise reduction
on 40 and 20 with the preamp on. Is anyone else experiencing this? Any
ideas? I'm running the current firmware.
