[K3] RX Audio/AGC
Locked
 
|
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 the qth list as daily digest and yahoo as individual email. It's much easier to respond on yahoo. I've posted to both. Thanks Mike R RIP- Mr 500.

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 attenuator on may help as well. Then too, if you are running with noise reduction turned on, that could create some 'funny situations' that are similar to what you are hearing - try with NR turned off. 73, Don W3FPR On 1/23/2014 6:39 PM, [hidden email] wrote: > I have a ongoing nuisance.

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.

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.

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 fast or slow. AF limiter 30. Signal around s7. I run into this frequently on a 20m rag chew net. 73 Mike R RIP- Mr 500. STP's Andy Granatelli from racing fans everywhere.

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

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.

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.

I my be wrong Mike,
but I don't think the AF Limiter is active *IF* the AGC is active my understanding is it is only active if AGC is *OFF* Quote from pg 15 of K3 owners manual D10.pdf: AGC off/on (when off, an AF limiter is available; see CONFIG:AF LIM) also pg 53: AF LIM NOR (Advanced.) Adjustable AF output limiter for use when AGC is turned off. This can protect your ears if a large signal appears. Signals or noise above the threshold will sound highly distorted due to the limiting action, reminding you to back down the AF or RF gain. Typical settings for those who often turn AGC off are 17 to 23; some experimentation will be required. On 1/25/2014 6:35 PM, [hidden email] wrote: > > > Hi Knut, > > Sorry I cannot.

Looks like this was because volume turned up too high.
I have tended at times to run RF GAIN backed off quite a bit thus requiring a hefty amount of volume of about 2 o'clock. I would then adjust RF Gain to the level of volume I wanted. It looks like some stations were strong enough to overcome RF Gain enough to distort with that amount of volume. So I'll have to alter my style in group QSO's with noise. Thanks Everyone.
