There is one claim that I thought was an exaggeration, until I heard
for myself. With the denoiser on and set very aggressive, the audio
output in the absence of a signal is so quiet that you'll think that
the radio is off. This in no exaggeration. On a quiet band with the
denoiser on, I find myself occasionally toggling it off just to
verify that the radio is working OK.
Like Steve, I've found the Noise Reduction to make received signals
'watery', BUT when I use it (and I ONLY use it mobile) it is
absolutely WONDERFUL for nearly making it as though there was a CW
SQUELCH feature in the K2. Virtually all(!) background noises
disappear and I only hear something when there's an in-band signal
present. Sometimes I leave the DSP NR enables throughout the QSO,
other times I don't. It depends upon what I'm listening for at the
time, but the NR DOES WORK.
On the other hand, I have never found the noise blanker to be
effective against the kind of noise present in my setting. Again,
the experience of different users varies according to their circumstances.
I've had GREAT experiences with the NB, and then some less than great
as well. MOST(!) times it'll do a very fine job of blanking spikey
interference, but then there are times when it's as though I never
turned it on.
Would I buy either again...yup... BOTH! Though, if you don't need
the NR feature of the DSP, the KAF2 is a nice, lower cost alternative
for CW reception. I don't operate fone, so I can't comment upon how
the DSP works on SSB.
