Tom, I believe you are speaking of functions that can be (and should be) implemented in DSP (if it is to 'search', some intelligence is required). The KDSP2 de-noiser does provide a lot of noise reduction similar to what you are describing - unfortunately, it is a bit more than $30,40,50.
The KNB2 deos a good job with impulse noise above the set threshold. The blanking width can be modified by changing a capacitor if a different width is needed for a particular noise situation. Beyond that, the addition of the KDSP2 adds the intellegence and levels of control to deal with other types of noise. 73, Don W3FPR > -----Original Message----- > > With technology available today I wonder if it would be possible > to design a > 2-stage tracking NB! > Just in the same manner as auto beat canceling. > I'm a better builder than designer , but can't help myself > throwing out some > thoughts on this. > Stage 1 when turned on search and lock on the noice pattern and > stay locked. > Stage 2 workes same way as stage 1 , but can be turned on after > stage 1 to > lock on a second pattern. > Each reactivation starts a new search for patterns. > Do some of you designers think this is possible? > I would gladly throw an extra $30,40,50 for a high performance NB. > > Tom LA1PHA K2/100 3829 , K1 1491 > > ----- Original Message ----- > From: "Darrell Bellerive" <[EMAIL PROTECTED]> > To: <[email protected]> > Sent: Monday, July 18, 2005 7:06 AM > Subject: Re: [Elecraft] KNB2 Performance > > > > Perhaps one of the design wizards that reads this list could > come up with > > something like this http://www.ussc.com/~turner/syn_blank.html > adapted for > > HF > > and the K2. > > > > My guess is that noise blanker effectiveness is directly related to the > > characteristics of the noise.
