Well truth be told I have been using my first K3/# 5299 since July of last it was a basic model I bought used, then a fully loaded one K3/# 6730 I bought the last 1/4 of 12.
I have not really noticed this all that much it does what I want it to remove carriers most of all. But what do I know I only listen to the 8-12 hrs a day in my spare time the rest I listen to my KX3, K2, IC-9100 or one of my old FT-101 lines of radios now 4 of those 8>). But since I sold my FTDX-5000MP that I owned for 2 years 90+% of my time has been spent using my K3's although sometimes it is hard to figure which Elecraft radio I want to use that day.

I too have noticed it and it really bugs me - very unlike the fine auto-notch filters found on the Kenwood, Icom, and Yaesu rigs. The nay sayers in this group will quickly tell you they don't hear it or give excuses for its existence. Don't buy into it - the distortion does exist and it is very annoying. To me, there is no excuse for the notch filter distortion to exist on the expensive K3 - when it does not exist on $1000 rigs. As a work around, I have found the following settings go a long way to eliminate the distortion. Be advised - these settings are for armchair copy on 75, 40, and 160 meters. I don't know if they would do well for contesting or DXing - of which I do neither. **K3 settings (Config Menu): AGC DLY - NORM AGC HLD - 0 AGC PLS - NORM AGC SLP - 4 AGC THR - 12 AGC F - 120 AGC S - 20 Shift - 1.4 Width - 2.7 RF Gain - 90 ATT - ON RX EQ 1 -2 2 0 3 +9 4 +12 5 +11 6 +14 7 -16 8 -16 Be sure to read the "Noisy K3" section on http://www.w3fpr.com/ - excellent information! The disclaimer: Your mileage for the above settings may vary - depending upon speaker selection, personal preferences, and your hearing acuity. Note: I made all of my settings by hand, using the K3 menus. I did NOT use K3 EZ as that program will sometimes upset the AGC settings. ** ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ----- No virus found in this message.
