[Elecraft] K-3 Noise Reduction

[Eugene Balinski]

All,

   For basic noise reduction operation, the ADSP-2 unit in
the venerable SGC SG-2020 is about the best DSP I have
heard.   IMHO it sets the bar for all DSP NR units.

   The NR has 2 levels.  The first level is excellent for
electrical noise and QRN removal along with a great
auto-notch function to remove tones, all without fatiguing
digital artifacts. 

   The second level is a deeper version of the first and
can be used during strong signal high QRN/noise situations.
 

   The NR chip and algorithm are now quite old in
electronics terms, but the technology is still valid and
offers a great launching point upon which to improve. 

73,

Gene K1NR
