Is the K3's filters an improvement to the K2's variable one? Are machines or
people building the factory assembled K3s? Has someone compared K2 and K3
side by side? Thank you!
The K3's filters are much better than the K2's, in terms of IMD
performance and ultimate rejection.
The K3 has both an analog noise blanker and a DSP noise blanker; the
combination is effective against the Chinese radar (at least as heard in
California!).
Note the DSP noise blanker is different from the DSP noise *reduction*,
which is an entirely different function. NR reduces background noise
which makes listening more comfortable, but does not remove pulse noise.
The K2 has an optional analog noise blanker and an optional DSP which
provides an NR function. The K3 comes with the analog noise blanker, the
DSP noise blanker, and the DSP NR function.
All of the above are much more easily adjustable on the fly in the K3.
I have listened to the K2 and K3 side by side and the K3 is much better
in many ways. Of course, it is also bigger, more expensive, and more
power-hungry (which might matter if you will run it from batteries).
