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 mu

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. STP's Andy Granatelli from racing fans everywhere. On Jan 23, 2014, at 11:04 PM, "Joe Subich, W4TV" wrote: > > Mike,

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 wr

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. Seems AGC should do that? Once again, it's like the high pitch voice is activating th AF limiter or a similar sound. AGC fa

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 in

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 wil

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. Yes, changing the slope may be helpful, but you will have to experiment a bit. Turning the preamp off and perhaps the atte

I have a ongoing nuisance. On USB it seems high voices will pop/crack just like if AGC was off and hitting the AF limiter. Reducing RF Gain clears it up. Turning agc threshold down has no effect. Is there a agc setting that might correct this? I haven't tried slope which is 15 (max). I get
