With any typical SSB filter bandwidth, AGC pumping is not a practical issue (it IS a big deal for CW however). Bill, I'm confused by that first sentence. How can a signal within the passband NOT pump the AGC? Normally when AGC pumping is discussed, it's a negative reference to an adjacent signal that's outside of the passband.

I agree. Although I routinely use 1.8Khz roofing filters in ssb contests, I doubt they help at all and are probably a waste of money. What does help to copy a weaker signal in the presence of splatter is to turn AGC off.

For more casual operating or on sparsely populated bands, the 1.8Khz filters do just fine for me. After all, it's 95% dsp. I find the advantages of the narrow roofing filter greatly outweigh any minor advantage of having a wider cw passband in contests. When running, they protect me from offending neighbors who would have otherwise ran me off my run freq, which occurs a few times in EVERY contest - far outweighs the one or two off frequency callers I might have missed. And in SP, the narrow filters allow me to hear that weak signal right next to that s9+ running station and give me those dx mults in 160M contests.

Re: [Elecraft] [K3] AGC-OFF
Dave Hachadorian wrote: There are two major problems with turning off the K3's AGC: 1. There is very little dynamic headroom until the AF Limiter causes severe distortion on even a moderately loud signal, even if the AF Limiter setting is max. That's not necessarily true, although probably true with most headphones on the market. Assuming non-impaired hearing, the effective dynamic range will be highly dependent on your baseline (ambient) noise level and subsequent gain settings. That's why K3NA strongly emphasized the need for high isolation headphone schemes in his original treatise on AGC-less contesting. The higher the isolation, the greater the ability to hear low audio levels, the lower the needed gain setting, and the greater the dynamic range before onset of distortion/clipping/painfully Loud levels. With the highest isolation schemes, distortion/clipping rarely occurs while the weakest signals are still rendered audible. I know that in-ear type phones (ear buds) can be very successful in this regard, but long term comfort is suspect. Every over-the-ear headphone I've tried so far that was touted as high or extreme isolation didn't quite deliver the degree of isolation that was hoped for, and weren't any better than my Sennheiser HD-280. I'm still searching for more isolation without compromising comfort. 73, Barry N1EU -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-AGC-OFF-tp6500910p6503775.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] Receiving/transmitting into an empty antenna jack
Decided to listen on 6m today for the first time, ever. Heard a bunch of signals, then tried to tune my multi-band dipole with the ATU. Seemed to tune, but was erratic, and even worked a few stations in the contest. Then, noticed I was on ANT2, which is empty. Switched to ANT1 and it worked much better ;.) How was it I was able to hear and work anything on (an empty) ANT2?

[Elecraft] K2/100 #6459 alive and well
I would like to thank Gary and Richard for all the help that they gave me in trying to sort out a distorted audio problem on transmit that I had with my K2/100. I did not seem to be able to resolve the problem, so looking at the list on Elecraft's Website of Hams in the UK that might be able to help me I contacted Dave G3TJP. He said he was willing to have a look at it for me so I took it to him, to cut a long story short Dave found several problems and was able to sort them out for me. There is one outstanding fault but it is not affecting it's operation, that is I have lost the voltage/current measurement caused by a damaged MCU on the control board also CP U3. I will replace these items at a later date to bring it up to full spec. So thank you Gary, Richard and Dave and any others I have forgotten for all the help. I know of no other Amateur Radio manufacturer who offers such a first class support and help service to their customers.

Not necessarily - if you have a low ambient audio noise floor (isolating headphones, quiet room, etc) then you can have a wide audio dynamic range without constant cranking of the RF gain. Several of us have been evangelists for this for quite some time and you can search archives/Web for more info.

One filter offset is -.94, the other is -.81 In order to do diversity receive, I have to set them both to about -.88 My question is: what happens when you set a filter offset differently than the one specified (as in my case) ? How is this supposed to influence operation (normal as well as diversity mode) ? How can things be improved, short of buying new filters? By offsetting the 2.7Khz filter center freq, you may incur some slight asymmetry in the passband response at the lower and/or upper knee of the response curve, but the vast majority of the passband will be unaffected. If noticeable, it will be relatively minor. The other options would be to use closer matched 5-pole filters or use 8-pole filters. 73, Barry N1EU -- View this message in context: http://elecraft.365791.n2.nabble.com/Re-k3-receive-audio-tp6259940p6271081.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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

Ron AC7AC -Original Message- Like some other threads, I'm baffled by this one. I installed the KDVR3. I recorded some stuff from my Heil headset/boom mic I got from Elecraft [iC element I think, plugged into the back jack] without messing around with any of my audio settings. I played them back in TX TEST mode, and they sounded like I sound to myself in the monitor audio, including audio levels. I played them for a nearby buddy and talked to him. He couldn't tell the difference. In the WPX SSB last weekend, I got 3 unsolicited Great audio reports, one from 9K. I have my TX EQ set as Jim, K9YC, has posted here several times, strong low cut and moderate high boost. I'm nearly deaf, so I have my RX EQ for SSB set to try to approximate the shape of my digital hearing aids. It doesn't have near the gain they do, but it does help. I have recorded off-the air [same buddy], and played it back to him on the air, both with my normal TX EQ and with it flat. He can definitely tell the difference. As I said, I'm baffled by this thread. My KDVR3 was literally plug and play. I first used it in the ARRL SS for the static part of my exchange and CQ. Several people said [unsolicited], nice to hear recorded audio that sounds like you do. If there's a separate gain control for it in the latest firmware, that's OK, I'll just ignore it. 73, Fred K6DGW Auburn CA 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:[hidden email] /user/SendEmail.jtp?type=nodenode=6225767i=0by-user=t This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html If you reply to this email, your message will be added to the discussion below: http://elecraft.365791.n2.nabble.com/Is-DVR-audio-really-getting-equalized-and-compressed-tp6210714p6225767.html To unsubscribe from Is DVR audio really getting equalized and compressed?, click here http://elecraft.365791.n2.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_codenode=6210714code=dzJ1cEBjb21jYXN0Lm5ldHw2MjEwNzE0fDEyODM3ODA5MTk=. -- Barry Kutner, W2UP Lakewood, CO -- View this message in context: http://elecraft.365791.n2.nabble.com/Is-DVR-audio-really-getting-equalized-and-compressed-tp6210714p6227290.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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

I'm using a subjective term because that is what it SOUNDS like, both in my monitor and over the air. I don't have a scope, so all I can go by is PERCEPTION, which is really the bottom line. I'm just trying to figure out why and how to fix it. I'd be happy to try it on the air with you, or anyone else willing. 73, Barry W2UP On 3/26/2011 10:07 AM, Guy Olinger K2AV wrote: I think a part of the problem is the use of a very indistinct term, lackluster, which could refer to low volume, frequency response, desired artifacts of compression, etc. Can you be terribly specific and technical about what you mean by lackluster? It has been a measured fact since the middle 20th century, that people do not hear either highs or lows as well as midrange when the volume is low. This lead to the addition of a loudness setting in stereo amplifiers which artificially raised the level of lows and highs to have the same PERCEPTION of full frequency range at quieter listening levels. Not surprisingly some found the sound harsh at higher volumes when the loudness was engaged. If you have your monitor level set low for DVR playback, and you have normal human hearing, you WILL hear LESS highs and lows. Comparison of two results for sound spread and brightness must be done at equal volume levels, or your ears will deceive you. 73, Guy.

When listening thru the MON, live audio sounds much better than the DVR playback of my callsign. Does recorded audio in the DVR go through the TX EQ filters either when recorded or during playback?

Re: [Elecraft] Elecraft at the Orlando ARRL Hamcation this weekend
I just left the Elecraft booth an hour or so ago and the K-Line (LOVE that name) did look great with the K3-P3-KPA500 combination bolted side-by-side. With the amp at 26 pounds in weight per Eric, I'd guess the whole station comes out well under 50 pounds . Of course you have to add a DC supply for the K3 but you might still get in under 50 lbs overall even with a KAT500R added. IMPRESSIVE!! I live in Silicon Valley not that far from Elecraft and that's USUALLY where I see Eric. But I'm in Florida visiting a relative so thought I would check out the Hamcation. Since Eric wasn't expecting to see me it was fun to see his little double-take when he did and admitted to wondering for a millisecond if he had REALLY just traveled 2500 miles :-) It's a pretty decent show - check it out if you can, 73, Barry K6RM __ 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] K3: APF effectiveness
What you're describing (hear signals that aren't even there) sounds to me like the APF is working just as intended. You're hearing faint ringing at your sidetone frequency when no signal is present. When a signal is present and tuned in, it will have precisely that same tone but will pop further out of the noise than that phantom signal. It just demands a little practice and patience along with fine tuning. If someone wants a lower Q APF with less gain, they should try a dsp width of 50hz without APF. 73, Barry N1EU Ralph Parker wrote: ...perhaps less gain and a little wider BW or give the user the tools to do it ourselves. I was thinking exactly that myself last night on 160m - no problem with the bandwidth, but I'd gladly give up a db or two of APF gain to reduce the ringing. Because of the ringing, I can hear signals that aren't even there! -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-APF-effectiveness-tp5961155p5961190.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] APF ringing
Bob, I'm not sure how you are using the APF but I'll make a few general comments from my experience with it. The APF is intended for occasional use only on weak signals that aren't much above the noise level. And when used, it requires careful fine tuning so that the signal is precisely centered in the K3 rx passband. The over powering and ringing is by design, to make it effective in popping those tuned-in weak signals out of the noise. The APF was never intended to be left engaged while tuning the band. 73, Barry N1EU Bob Lanning wrote: Is there away for the user to adjust the APF?

[Elecraft] K3 line out
I've starting using the K3 line out for the first time driving some powered speakers and really enjoying some great sounds. But I was surprised to find that with my subreceiver turned OFF, there is no audio on the line out right channel. I was expecting mono audio with main rx heard through both L R channels. The subreceiver audio comes through fine on the right channel when it's turned on. Can some other folks please check their K3 line out and please let me know if you hear the same thing?

Re: [Elecraft] [K3] Matching 5 pole filters in main and KRX3
No, you need to use the same offset values for the same filter position in the main and sub receivers.
