David, Wow, the default Beta and Decay settings leave me with a lot of distortion. I can tolerate more distortion on SSB than on CW. The denoiser makes CW sound scratchy, but till copyable. I left the Beta setting close to the default, but really reduced the Decay setting. I put it down to 30, though I did have it down to 5 at one point.
I guess I am used to DSP with less distortion. My 756PROII is able to reduce the noise level without the degree of distortion present in the KDSP2. The KDSP2 does get the job done. I starting to prefer the bandpass filtering over the denoiser, and only use the denoiser if really needed. For example, I use the narrowest filter setting of 50 Hz, for the CW bandpass filter. I've found it can work better than the denoiser in most situations. 73, Steve N6VL K2 #2289 -----Original Message----- From: David Wilburn [mailto:[EMAIL PROTECTED] Sent: Sunday, October 21, 2007 10:20 AM To: Steve Kallal Cc: 'Elecraft Discussion List' Subject: Re: [Elecraft] K2 - DSP - Impressive I set everything back to the default settings. Then the only ones I ended up change was the SSB & CW gain settings. After that, when I want to use the DSP, I would step through the different "freq widths" that are supplied by S1(NR1, NR2, NR3, NR4), then S2(NR1, NR2, NR3, NR4), and so on. This is the piece that I did not "get" the first time around. My initial tinkering had focused on the settings you mentioned. But it seems to me, that tinkering with Beta and Decay, before you have worked through the existing setup, that is the application of the various filter widths to you problem noise, is going about the process from the wrong end. Perhaps Lyle can explain it better. I hit DISPLAY to get into the DSP settings, usually C1 .nr (for CW) or S1 .nr .nt (for SSB) is seen at this point. If not, press RCL untill one of them is visible. Then pressing STORE brings up C1 .nr1, pressing STORE again, brings up C1 .nr2, and so on till you are back at C1 .nr1. If I do not find a suitable setting in the first 4 filter settings, I then press AFIL to take me to CF2. Now pressing DISPLAY followed by STORE brings up C2 .nr, and I can go through these steps again. This cycle can be continued through CF3 and CF4. In performing these steps, I have not needed to fiddle with Beta and Decay. I assume and changes to Beta and Decay, impact all 16 filters per mode. Hope this helps. It sure made a big difference in how I use the radio.
