I've found that playing with the AGC SLP and AGC THRESH settings has really helped me out in this arena. I found that especially with the narrower filters that I was having this issue. You also want to make sure that you don't have too much additional gain thrown in for your narrower filters.
My rig is at S0 with no antenna input and the noise is very reasonable. I did have similar problems and concerns about my rig and the AGC settings have helped me in this area. I set the two main AGC settings into my PF buttons and have found that they are useful for allowing you to make changes to better fit band conditions as they change. One thing I'd like to see is that instead of PF1/2 only taking you to one menu item it could take me to the menu at the item of my selecting. That way instead of having to put AGC SLP one PF1 and AGC THRESH on PF2 I could just use AGC SLP on PF1 and then THRESH is just one click of the VFO B knob away. Then I can setup another area of the menu into the PF2 button. I wonder if I can use bank 2 of the M1-M4 buttons as separate quick jumps and still use the main bank for CW memories... Guess I'll try that when I get home. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of THOMAS BAILLIO Sent: Friday, August 08, 2008 6:09 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Receive audio in CW I've had the K3 for 4 months now, but I'm new to the list. So, forgive me if this has been discussed previously here. Overall, it's been a great rig and I'm encouraged by Elecraft's commitment to firmware upgrades. However, I see few minor annoyances with the K3 receiver and I wonder if others are also bothered by them: - First of all, in the prescence of summertime QRN the receive audio is a bit harsh. Static and noise in general seems more bothersome with the K3. Lowering the CW pitch, applying IF shift and reducing the width (the 400 Hz hard filter is installed) all seem to help by lowering the noise spectrum, but don't really mitigate the problem. Applying RCV-EQ doesn't seem to help. It almost seems the noise is aliased. - With the antenna removed and the input grounded or terminated, the background (audio) noise on all bands seems unusually high. - Also, with the S-meter configured for "absolute" and no antenna, the S-meter shows a 1 to 2 S-unit background level increase when ATT is enabled. I expect this is simply a software calibration issue.
