Re: [Elecraft] [K3] RX Audio/AGC
This debate comes up way too often - so I rather think there is an inherent problem with the perceived comfort of the receive audio. First, I am a long-time Kenwood user and am very used to armchair copy - as most of my hamming is rag chew on 75 and 40 meters. To that end, I have spent too much money on speakers and too much time trying to get the K3 to sound as good as my TS-480 or a TS-590. That said, you can see the current settings I am using on my K3 at: http://www.w2blc.net/K3.htm The above captioned settings are not carved in stone and I tweak them often. Tweakability is one of the strong features of the K3. You can arrange the radio to suit your specific needs and desires - not just what some lab-rat decided at the manufacturer.

Joe, Thanks. I should double check AF Lim. I've always set at 30. EQ mostly flat with band 8 -16. I may experiment with -3 or -6 on some EQ bands. 73 Mike R RIP- Mr 500.

Re: [Elecraft] [K3] RX Audio/AGC
Mike, The high pitched voices should have no connection with AGC. I would suggest that those signals are off frequency. Using the RX EQ might help, or reducing the HiCut may be the answer to make your RX more comfortable. 73, Don W3FPR On 1/23/2014 11:33 PM, mikerodgerske5...@yahoo.com wrote: Let me add, I don't mind reducing rf gain more one on one BUT its aggravating after a while in a group to turn it up and down for one or two guys with high pitch voices.

Re: [Elecraft] [K3] RX Audio/AGC
Adding on Don's post, my experience is to go slow, make one change and try it out in real situations. I was about to give up on the RX Eq, and got that advice from K9YC. I did finally zero it in where I want it. With a radio that has as many configurable parameters as the K3, some of which interact, it's very easy to get things totally out of whack with big and rapid moves. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 1/23/2014 3:55 PM, Don Wilhelm wrote: Mike, I don't know if it will help in your situation, but take a look at my webpage www.w3fpr.com article on "Noisy K3" for some guidance to setting the AGC parameters.

Re: [Elecraft] [K3] RX Audio/AGC
Mike, An added note - when experimenting with the AGC settings, do take heed of the information on how to evaluate the results of your changes - listen between pauses in the signal rather than listening to the noise on the band. Listening to the noise level without an intermittent signal will lead you in the wrong direction. 73, Don W3FPR On 1/23/2014 6:55 PM, Don Wilhelm wrote: Mike, I don't know if it will help in your situation, but take a look at my webpage www.w3fpr.com article on "Noisy K3" for some guidance to setting the AGC parameters.
