Re: [Elecraft] Re k3 receive audio
This is in response mostly to Guy,K2AV's post. I am ashamed to say that I really didn't know better . Not having much experience with HF equipment I just assumed that it was meant to be really noisy and just lived with it. :) Of course this really annoys those around me so it tended to limit the time that I could enjoy the radio without headphones. Not to mention my aching ears after a 30 minutes under the headphones :) Thanks to your explanation and suggestions Guy you have increased my enjoyment of the K3 1000 percent and made me REALLY appreciate the difference in performance between my FT-897 and K3. The K3 is truly an amazing radio. I have had mine for almost a year now and I continue to be happily surprised by it. Now if I could only find a K3 equivalent on the VHF/UHF bands. I know, transverters are the preferred path for weak signal work. But I would still prefer a dedicated high performance radio for the VHF/UHF bands as it would better suited in general as an IF platform then an HF rig. Until then I have invested in an XV222 and Kenwood TR-751a. I will probably end up purchasing another K3 for use as a dedicated transverter platform to launch myself up into the microwave bands especially now that the K3XREF will be available soon.. In any case I would like to give my thanks to Guy and all the others on this list that are patient enough to provide meaningful explanations about why things work the way they do. I also want to give my ongoing thanks to all those at Elecraft that continue to provide some of the best equipment and customer service available at any price... -- Thanks Jon KG6VDW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Re k3 receive audio
Yes, it certainly IS that simple. I remember the old radios well. They never had the problem. They didn't have enough gain to have the problem. Nor was it possible to have the AGC recover in such a short interval that the noise sounded as if it were the same level as the desired signal, even if many S units weaker. Using RC timing only and a single voltage bus, really fast AGC produces really obvious distortion. So why have digital methodology that can produce setting combinations that produce roar-in-your-ear behavior? Very simple. People wanted the options and to be able to set it just like they wanted it, so the available ranges of AGC constants were set to allow people to set it to taste. If you go back and read the archives, people were pretty sharp-tongued about having all the options. But whether consciously or not, many (most?) people were EXPECTING the K3 to sound like Pappy's analog radio, and divergences were reported as K3 troubles, and still are. AND, as it has always been on the old radios, once AGC was on the scene, the only setting used for RF gain was wide open. And wide open is now 30 db farther down than Pappy's old analog radio, AND can do all that without distortion. Someone was asked why he was running RF gain at max and PRE on on 80 meters. He thought about it a while and said he guessed because he always had. And sure enough, looking at a now idled older Yakencom rig, that's how it was. Turned it on and the older rig *NEEDED* the PRE on 75 meters for morning SSB. And right beside that was an old Ameco preamp to put in front of the radio's built-in preamp if you wanted to hear anything weak on 15 and 10 meters. RF gain maxxed out is just habit and we are taking some time getting used to stuff that doesn't act like the old radios. On my K3 on 80 and 160 I use the attenuator on and the preamp off when listening to the transmit antenna. I have an on-the-ground loop array listening antenna, and when listening to that have ATT off and PRE on. The 20+ dB difference between ATT on and PRE on almost makes up for the RX antenna's normal very low gain. If I flip the RX source with the RX front panel button, the K3 seamlessly switches the ATT and PRE in and out. Very nice, very handy. It also makes for stellar diversity because the same trick is available for the second RX. That very useful convenience being in play for anyone who buys a K3, means that everyone has to understand PRE needs to be OFF and ATT ON for 80 and 160 listening on transmitting antennas, and adjust accordingly. Fail to do that, and somebody has a K3 noise problem. But the fix is between the ears, not in the K3. SETTINGS, which is what we are really talking about, are the user's problem. I'm watching my incoming noise tonight on 160. S5 between strike QRN, with that up to 20, 30 or 40 over. That's something like -100 dBm steady. -100 dBm just tickles the S-meter on my MP. On the K3's S-meter, where calibrated S units ACTUALLY ARE six dB per step, S0 actually *IS* 54 dB below S9, which actually IS -73 dBm. So, watching both of them, the K3 is five S units noisier than the MP, or that's how it gets reported -- my K3 is terribly noisy on 160 and 80. Add to that the maxxed out RF gain, plus PRE turned on, plus unfortunate user-chosen ACG settings and the user expecting it to act like old analog radios, and not understanding the differences, we have one unhappy owner. My MP's S meter is a liar. What was really going on was that the AGC and the signal measurement ARE THE SAME CIRCUIT, as they have been in all the old radios. The truth of the matter is that S0 (no deflection) is 54 dB below 50 microvolts across 50 ohms or -73 dBm. So S0 is -127 dBm. Our old radios had NO chance of AGC engaging at -127. A lot could not even HEAR -127. So the S-unit scale was a lie TO BEGIN WITH. What radio manufacturer is going to tell the truth and start his S-unit scale at S5? Now you have explained the MP's compression of S-units into 20 to 25 dB. And what manufacturer is going to take the AGC bus and show how cramped the range is on top, and put S9 to 40 over in the right 1/6th of the scale? So on the old radios you have a meter that doesn't show you much more than one signal is louder than another. Calibrated K3 tells the truth. The firmware program analyzes multiple states in the radio, and runs it through a calibration table to compute the actual signal strength. Personally, I wish there was a way to have the K3 (by itself) read out in dBm at the antenna. The K3 ain't your daddy's analog radio, however much we are unconsciously looking for that. But once you learn and get used to the new stuff, you'll never wanna go back. No way. 73, Guy.

Re: [Elecraft] Re k3 receive audio
Guy, Again your ability to write down what is REAL and what is NOT is again 'right on the money'. This last post of yours should be REQUIRED reading by all new owners of the K3 to help them better understand the radio, the design and the capabilities. Maybe even a version of your explanation should be included in the K3 manual or at the very least be included in a 'TUTORIAL' available to all on the Elecraft website. Thankyou.

Re: [Elecraft] Re k3 receive audio
Guy's analysis seems to identify the key point. You can definitely get better reception under noisy conditions by going into SX-101 mode, turning the AF gain all the way up and riding the RF gain with your left hand. This reduces the AGC effect, possibly defeating it altogether, depending on where the RF gain is set. As Don points out, the first step is to go to the Config menu, and set slope and threshold (0 for slope and 15 for threshold minimizes the noise enhancement of AGC). When that isn't enough, you can leave AGC on and tune as described above, or turn AGC off altogether; this gives good results, but requires even more constant cranking of the RF gain. I have noise not only on 80 and 160, but often on all bands. Sometimes when using this technique I can find a setting for RF gain that is right below some sort of threshold where the noise suddenly jumps into my ears. Re-shaping the AGC in this way almost always improves the K3's signal/noise audio as I perceive it when digging for weak signals. Perhaps some manufacturer, or maybe all manufacturers, will soon figure out a way to handle this automatically.

Re: [Elecraft] Re k3 receive audio
Tony, Why would we want manufacturers to give us a fully auto-magical, panacea radio that simply becomes a proverbial Black Box that we simply turn on and speak or operate in other modes? Elecraft are leading the way I feel in giving us some serious weaponry to fight widely varying conditions. The sun spot cycle is changing, so are signals we are receiving. I personally enjoy being able to dig that low down in the noise signal I hear with the K3. Something I am unable to do with the other radios I have had and used with the same antenna systems I have now. History shows us that manufacturers have tried the fully automatic approach and have now shied away from that by offering more knobs and buttons, FW selections and tweekability in their current products than ever before. Maybe, just maybe, a fully automatic design radio will only give us limited ability to override the receiver and create just another set of radios that perform worse than the current crop on the market. I want the choices I have now and I am happy with the K3 development to date. YMMV Gary On 14 April 2011 08:50, Tony Estep estept...@gmail.com wrote: Guy's analysis seems to identify the key point.

First of all, thanks for all the helpful replies. Second, it is possible to get someone to see the light. Early indications are I like the method of using hi/lo cut for ssb. I just didn't want to give up using shift and width. I see how much better this works and also for maximizing the sound quality of a given received signal. I believe this method makes the k3 sound better. I have the receive equalizer set to zero and using hi/lo to make the cut. Does this sound right? Are any of you tweaking the receive eq? I don't really see the need for receive eq when using hi/lo cut on ssb? Thanks so much. An old dog learning new tricks.

I've since discovered that narrowing the bandwidth to 2.4 removes a lot of noise so I'm currently trying that and have changed the equalizer to a more neutral setting. I think I'm liking that better. I like to use width and shift. I like to know where their at but I know a lot of Operators prefer hi/lo cut on ssb. I'll soon try that as well and hopefully find That full audio with non irritating noise. 73 Mike R Sent from my spy ring __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
