Doug, I am not going to really answer your question, but give it some "food for thought" - most true Noise Blankers will not work on RF hash (which I would interpret as a "frying noise" mainly because it is too constant. If such a constant noise were to be blanked (the IF would be interrupted for the duration of the noise), then you would also kill reception. There are some radios with buttons labeled NB that do more of a "noise reduction" function rather than full blanking, and may be effective for those more constant types of noise.
Yes, the KDSP2 does do Noise Reduction, and does it quite well. Whether it will handle your particular noise is to be determined. If you can find someone with a K2 equipped with the KDSP2, you would want to try it at your location to see if it will handle your noise. If you do borrow, you may want to try several of the variety of setting available on the KDSP2, so record your friends settings and restore them before you return the K2. Just a note - some users of the KDSP2 do not know that the noise reduction parameters can be adjusted, and they just use whatever the defaults are. You may need something different than the defaults, so some experimentation may be required. 73, Don W3FPR On 10/4/2010 9:00 PM, Douglas Furton wrote: > I wrote a week or so ago for some advice about testing my K2 noise blanker. > From the replies I received (thank you), I now know that my blanker is > probably working FB, but isn't well suited to blank the type of noise that > plagues my QTH. > > So, I would like to ask anyone with the K2 DSP option if any of the noise > reduction schemes implemented digitally are good at blotting out the type of > I can't seem to get rid of. > > The noise I'm complaining about sounds a lot like the type of RF hash one > might expect a noise blanker to get.
