Re: [Elecraft] K3 FIRMWARE, Rev. 3.25: Improved NR, 10-Hz SHIFT steps, Received CW WPM display, VFO noise reduction, etc.
Strange operation here... AGC-S seems to work as it should and AGC-F as expected but if I turn AGC off my rig does silent. I'm still able to see the S-meter swinging to the signal that I was listening to. Current settings are as follows: AGC Decay = Soft AGC Hold = 0.00 AGC Pulse = Normal AGC Slope = 10 AGC Threshold = 7 AGC-F = 120 AGC-S = 20 I've made a few changes to this setup and I'm unable to get a sound out with AGC off. I've performed the SPI clock mod and the extreme signal protection mods. I've tested with both AF and RF gains maxed and the output it still silent. I've also fully swiped the range several times to rule out a dirty pot.

You know I even told myself about that parameter but then talked myself out of thinking it was that because I was under the impression that that feature was in play regardless of if AGC was on or off.

I then found another tone that seemed to be drifting back and forth a little bit and hit the auto notch on that. It seemed to notch it but was following it a bit slowly so it was just off of it every so often but it was updating and keeping things quieter.

[Elecraft] [K3] K3 ATU tunning discrepancy
Hi, The other day I was tuning up on 20M (14.220Mhz thereabouts) and noticed my SWR on the K3 was at 5.3. When I put up the antenna, it was tuned to a less than 2.0 SWR. Accounting for wear and tear over time I thought it might have slipped a little, so I re-tuned the antenna back to 2.0 SWR. Back at the tx it still shows 5.3 and checking on the the MFJ-259B it's still at 1.9-2.1. What could cause the big difference? BTW the antenna is a HF6V vertical. Most of the other bands show little difference over all. The K3 was matching 1 to 1. Any ideas. I'm going to take down the antenna and do a full cleaning as it's been up for a few years. -- View this message in context: http://n2.nabble.com/K3-ATU-tunning-discrepancy-tp3449460p3449460.html Sent from the [K3] 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] K3 new V3.25 NR not so good for CW week signal
Hello, After testing new beta 3.25 I have fond that new NR software has lost the ability to make weak signals to stand out on low bands. This was one of the best features the K3 had in small and bad QTH like mine, 3 BC and a Big Power Station, all of them at 1 to 2KM away, you can not imaging the QRM I have. I have read here many K3 users in this list are very glad with new NR, I suppose are SSB operators and most using it on normal conversation and not very weak signal. The new NR is quite good for chatting just in the line of my old IC-PRO2, there is no much difference changing the adjustments like the old NR but for CW the old firmware with narrow roofing filter, looks to me a bit but better as an old FT-1000 Peak Filter, very good for 160M. Maybe it could be add in a future firmware for CW operators as a digital Peak Filter similar to old NR. So for me or I go down to V3.19 and missing all new improvements or use my old FT-1000 for Low bands, which is not very good after all money I have spent in my full K3. Thanks, 73.

[Elecraft] [K3]Advice needed from audio grounding experts
Hi all, I am making up a cable set to connect a Pactor modem to the K3 and wish to avoid ground loops. The connections to the radio are: PTT Power (from the 12v out connector on the back of the K3) Line in Line out According to the schematics one end of the K3 line out isolation transformer is DC grounded and the line in transformer is DC floating (just to be clear I am talking about the windings for external connection). The modem only has 1 ground connection. I obviously need to connect audio out and ground from the modem to the line in on the K3 and this will not provide DC ground. My current thinking is that I connect the modem ground to the 12V ground on the K3 accessory socket to provide the DC ground. Shielded cables would be used for PTT and the connection to the K3 line out with the shield disconnected at the K3 end. Is this the best approach?

Re: [Elecraft] [K3]Advice needed from audio grounding experts
Hello Paul I took the pre-wired cable that came with my PTC-IIex and terminated the cable in a plastic project box, I connected all 4 of the braid of the screened leads to/from the K3 to the braid of the cable to the SCS modem. The white wire (pin 2 of the DIN plug) on the cable from the modem also connects to the braid at that common point. You might at some stage consider making a switch box to avoid needing to keep swapping those audio plugs when using sound card modes, a cheap 4 pole 3 way rotary switch works well, just needs a few sockets on the rear panel of a small box and you're in business. It saves wear and tear on the rear sockets of the K3. 73 Dave, G4AON K3/100, SCS PTC-IIex - I am making up a cable set to connect a Pactor modem to the K3 and wish to avoid ground loops.

Re: [Elecraft] K3 VFO Tuning noise reduction
Eric - I've switched the settings back to SPI1 until I have the parts to perform the HW modification. I'm curious however; SPI2 totally eliminated the noise for me even without the hardware mod in place. The communication errors you mentioned, could those lead to permanent hardware failure if someone where to use SPI2 without the resistor/diode combination? Anyway, when I was beta-testing this release, there wasn't any mention in the release notes of a hardware change being required in order to use those functions, hence my surprise.

If you have a computer connected, you can also set power with the PC command. I realize not everyone has or wants a computer connected at all times, but it is another way.

[Elecraft] K3 : toggle between two powers ?
K3 is wonderfully flexible and though mine is only a few weeks old I see it's getting more flexible. BUT. I'd rather not see a scenario where a PF gets dedicated, leaving me without any way to access variables I want to be able to change in real time. In fact I would be real pleased to have more PF buttons. Obviously you can't add buttons to the panel. Conceptual idea: an accessory of tethered knob and programmable button array. OK, OK, not high tech, or now enough? Make it Bluetooth instead of tethered, with a microphone jack, headphone jack, little built-in hi-fi speaker, operating from a single AAA NiCad that you replace once a year like a smoke alarm. Oh, and a couple of belt loops.

Benny, If you are willing to use the K3 Utility Command Tester, then you can read or set the K3 power using the PC command - see the K3 Programmers reference for a full description.

Re: [Elecraft] K3 new V3.25 NR not so good for CW week signal
Many FT-1000D owners (and non-owners who have used them) have urged implementation of an Audio Peak Filter in the K3 for weak-signal CW work. The APF on the FT-1000D is exceptional and it's a true gain-producing peaking filter at the center frequency. By contrast, the APF in the Icom 7700/7800 is probably better characterized as an audio bandpass (ABP) filter with no peaking gain at the center frequency. I suppose the ideal APF would incorporate all the attributes of a single-channel parametric EQ with variable Q, frequency, and amplitude.

Re: [Elecraft] K3 new V3.25 NR not so good for CW week signal
Kent, very well put and very true. So far this one very simple feature has kept the K3 from being at the top of the line so to speak. (tin hat on, keep your flames to yourself) It all boils down to having the two radios side by side, and operating weak signal 160 meters for instance. Both receivers hear the signal exactly the same, but a touch of the APF on the old 1000D brings the signal out of the surrounding noise just enough to make copy possible. If you cant hear them you cant work them, and this is the case time after time using the K3, I have to resort to turning on the 1000D to make the contact on extreme weak signals on 160. I am sure others will disagree, and a large part of the K3 ownership may never work with signals that weak, or work 160 even. But for those of us who do the APF is a major tool. To continue to try and duplicate such a simple feature in DSP is just work for naught, the reason its APF is it is Audio Peak Filter, a one chip solution in the real world, and with the rxEQ already in the K3 seems to me a former programmer a simple audio implementation. If some dont like, dont use it. I can only imagine how long the want list must be, and how many times its reshuffled, and unless someone has hollered about it recently it drops down the list even further. For a temporary fix I use an external Datong peak filter, not near as good as the 1000D internal, I will limp along for a while longer, but not forever. 1000D may be ancient technology but if it copies signals the K3 cannot, then all the great numbers on paper in the world do not help you out. The K3 blows the 1000D out of the water on selectivity and close in signal handling, but 90 percent of the time there is no QRM near the weak signal. To me its like the beer commercial that states Drinkability.. On 160 weak signal reception, you need Receivability.. Just want the K3 to be all it can be. 73 Merv KH7C ex K9FD Jaime . . .

[Elecraft] K3 new V3.25 NR not so good for CW week signal
I've noticed in homebrew receivers as the bandwidth narrowed, shedding noise and QRM I preferred the gain to go up, increaseing the in-passband signal amplitude. I always attributed it to formative years with a Heathkit Q multiplier. It may be an effect similar to AGC with adjustable flatness (May 1996 analog circuit, in DSP of K3). I found I preferred to have strong signals sound louder rather than perfectly flat. Prolly a psycho-acoustic explanation (or maybe just get my head examined?). In firmware one could increase the audio gain by an adjustable amount as the IF bandwidth was decreased, with an operator-settable scaling number. Say 0 = gain independent of bandwidth, to 100 = gain multiplied by K * (2800/DSP bandwidth). Very similar to the AGC rise scaling. That sounds good to me. __ 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 will also rotate my beam during the net to listen north and south. See you there. 73, Phil, NS7P __ 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] Carrying Case for K3
W1UE wrote: I'm looking for a carrying case for my K3. I'd like it to be small enough that I can take it on an airplane as carry-on luggage. What size Pelican will fit? Any other suggestions? Dennis W1UE Hey Dennis The K3 will fit in a Pelican 1510 - about 1/4 of foam on each side, but that should be good enough for carry on - as long as you can keep it in sight or in the overhead. But I would not want baggage handlers anywhere to touch it! And you could probably get a switching power supply in the 1510 with it. The 1520 with a 1527 might be good to check in, but it doesn't look like it has wheels to pull through airports like the 1510 does. A 1527 alone looks like it might be about the same as a Rose Kopp case. I used a Rose Kopp case to take take my K3 to Nicaragua and was fairly apprehensive any time anyone came close to it! It is a very nice case for traveling by car or to Field Day etc but not on an airplane. This winter if I take the K3 again it will go carry on in a 1510 with wheels. 73HankK8DD __ 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 new V3.25 NR not so good for CW week signal
Not just Q-multipliers but go back another generation to the regenerative receiver (or, more properly put, regenerative detector). Same thing. As you narrow the selectivity by adjusting the regeneration closer to the critical point, the gain also increases, just as with a Q-multiplier. I've gotten used to turning up the gain as I narrowed the selectivity on my post-regenerative Homebrew receivers so I didn't miss it on the K3. Ron AC7AC -Original Message- I've noticed in homebrew receivers as the bandwidth narrowed, shedding noise and QRM I preferred the gain to go up, increaseing the in-passband signal amplitude. I always attributed it to formative years with a Heathkit Q multiplier. It may be an effect similar to AGC with adjustable flatness (May 1996 analog circuit, in DSP of K3). I found I preferred to have strong signals sound louder rather than perfectly flat. Prolly a psycho-acoustic explanation (or maybe just get my head examined?). In firmware one could increase the audio gain by an adjustable amount as the IF bandwidth was decreased, with an operator-settable scaling number. Say 0 = gain independent of bandwidth, to 100 = gain multiplied by K * (2800/DSP bandwidth). Very similar to the AGC rise scaling. That sounds good to me. __ 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] P3 first look
I had a short introduction to the P3 today from Wayne and Alan (N1AL) at the Santa Barbara ham fest. Wayne warned us that the P3 was an engineering prototype; I was expecting something less finished and with less functionality than what I found. It looked real nice sitting next to the K3. Display resolution is the first thing that I noticed, very high. The P3 and K3 were both propped up on their front bails. Having both units the exact same depth makes them match perfectly when sitting side-by-side. The prototype I saw had smooth black sides that matched the K3 finish. Wayne says there will be ventilation holes in the top of a production version. From Wayne's description, maybe 2/3s of the interior is open space for unknown future expansion ideas. There is a knob on the front to move the frequency cursor. Buttons are there on the right side of the display to change modes and select how much of the IF bandwidth is displayed. Up to 400 KHz and down to much tighter spreads. If I were operating CW on 40M for example I would probably be looking at a 30 KHz spread that covered a little bit more than the DX window. Other times I can imagine watching a much larger IF window, such as 10M phone. When I walked up the P3 was operating in split display mode with a waterfall on top and spectrum plot below. The waterfall is quite sensitive to picking up weak signals. I think it was Jim K9YC that said that his panadapter has led him to find all the troublesome wall warts in his house and quiet them. I can fully believe that this is going to be a result of many users of this technology as you will find all the donor signals readily. I asked if the P3 will have independent audio out (say of the cursor position). It is possible technically but is this really valuable? Hooks are in the K3 for the possibility to view sub receiver IF but the independent IF I/O isn't there so this isn't possible for now if I understood the answer correctly. The P3 sure has a wow factor going for it.

Re: [Elecraft] P3 Photo
My first reaction to seeing the P3 was that its front panel layout is presently designed for it to be located on the LEFT side of the K3. I know all the left handed people out there will say that's fine but as a rightie I disagree. Placing it on the left of the K3 it sits next to the front panel Mic and Phone connectors (with associated cables). It also sits next to the left mounted carrying handle (scratches from existing handle mounting screws). For me, this left side location forces me to shift the radio 7 inches to the right of my seating position. Guess I'm an old fart who expects various rig accessories (speakers, DMU's, scopes, etc) to be located on the right. I'm sure someone will say that all I would have to do is move the unit to the right side. However, the existing proto-type layout is not optimized for that location. Perhaps Elecraft will entertain reversing (flip) the existing front panel layout to allow optimized right side location. The only reason I can think of that may have prompted the P3's present location is the closer proximity to the IF Out/Accessory connectors, or all the designers at Elecraft are left handed ;-) Nice hi-res display, 400 KHz max display span, matching K3 esthetics.

Re: [Elecraft] K3 new V3.25 NR not so good for CW week signal
Not really, if you read the recommendations for the filters you will notice that caution is warranted for setting the gain higher than recommended, for IMD prevention if I remember correct. Kind of like the Inrad roofing filters, in some cases the gain is set to high and causes more IMD than without the filter. Some Inrad roofers for the FT-1000D had too much gain and the radio was worse with them installed than without. W8JI had some measurements on those issues.

Re: [Elecraft] P3 Photo
I don't see what you're talking about here at all.. Honestly looking at that picture I see this thing as optimized for placement on the right side of the K3. That gives you easier access to the select knob and the buttons along the right side. Hell if all else fails you can set the thing on top of the K3. Just because something is set on the left side doesn't mean its ergonomically designed to set there. It would do equally well on top of and to the right of the K3. Bout the only thing its not designed for is to sit below the K3. ~Brett (KC7OTG) On Sat, 2009-08-15 at 15:21 -0700, W6NEK wrote: My first reaction to seeing the P3 was that its front panel layout is presently designed for it to be located on the LEFT side of the K3.

Re: [Elecraft] K3 new V3.25 NR not so good for CW week signal

Kind of like the Inrad roofing filters, in some cases the gain is set to high and causes more IMD than without the filter. Some Inrad roofers for the FT-1000D had too much gain and the radio was worse with them installed than without. W8JI had some measurements on those issues. Merv KH7C This is sorta already there if you have multiple roofing filters. You can define the gain that is added when each filter kicks in.

I found I preferred to have strong signals sound louder rather than perfectly flat. Prolly a psycho-acoustic explanation (or maybe just get my head examined?). In firmware one could increase the audio gain by an adjustable amount as the IF bandwidth was decreased, with an operator-settable scaling number. Say 0 = gain independent of bandwidth, to 100 = gain multiplied by K * (2800/DSP bandwidth). Very similar to the AGC rise scaling.

Re: [Elecraft] P3 Photo
My only advice before it goes to production: Make the cabinet 1 wider, and stack some band buttons there. Maybe 2 wider with a bunch of programmable buttons that we can forget what they are programmed for. Loop the rs-232 signal through this box to send the band change commands.

[Elecraft] APF vs 10 Hz DSP, why they don't sound the same
After watching spectrogram on a noise signal and noting a much sharper shape on 50 Hz DS as an audio peak filter, I began to wonder about some of the posts I was seeing asking for APF. What was going on? After some measurements... 1) the 50 Hz DSP bandwidth is *narrower* at the top than any APF I have used. The 100 or 150 Hz DSP is more like it. 2) the 50/100 Hz DSP has *far* steeper skirts than the APF. 3) the APF *sounds to the ear* to drop off a signal more, but that is because the signal as it moves outside the APF is still controlling the IF AGC off the APF center, holding the input to the APF constant. In the 50/100 Hz DSP the AGC opens up the gain when one tunes off the signal, giving the *appearance* of no skirts. Watching the S meter will show what is going on. This effect dissappears entirely with the AGC *off*, where the signal falls off the table on the DSP skirts as one tunes away. If one simply measures the amount of discrimination between two close signals, the 50 Hz DSP can beat the APF by 10, 20 db or more. Listening to two S9 signals only 150 Hz apart, the 50 Hz DSP can completely isolate them. In run situation, the shift and 50 Hz DSP would allow me to pick up just one and then the other by remembering their respective tones, without changing my transmit or RX reference. The SOUND of tuning across a signal with APF in a 500 Hz IF bandwidth is illusory in close signal discrimination, even if it is one's favorite analog sound. Isn't this just dumbing down a superior DSP function to sound like an analog result? And reversing myself in one of my earlier posts, the modulation pops produced by the sharp skirt drops on 10 Hz shift increments off a strong signal are annoying, and perhaps the shift can be damped just a tiny bit to remove them. -- 73, Guy K2AV __ 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] K2 Guru needed KSB2 problem
Help please I recently purchased a K2/100 with a number of options including the KSB2 SSB adapter. (serial number 4000 plus) It was sold as a good working radio and it checks out ok at first glance. CW is working FB but the SSB is distorted with the MH-2 as it was set for this radio with the 5.6K resistor between pins 1 and 6 of mic jack. With the HC-5 Heil it sounds better but doesn't product the normal Christmas tree envelope on my scope. This is not an RFI related audio issue. It's the same sounding at low power (5, 10 or 100 w) or driving my KW amp By reading through the KSB Operation Instructions it seems that I might need to tweak the BFO as a refinement. However I've found that SSBA and SSBC do not adjust with changes in settings. In fact, SSBA Level 1 mic gain is atten 10dB and no changes on the scope or sound in another receiver all the way up to Level 4. Compressor Ratios from 1:1 to 4:1 on SSBC show no changes to the envelop on the scope or sound on a second receiver. This test was conducted with both the MH-2 and HC-5 Heil but the Heil sounds much better. Both these mics work well on my K3 Maybe it's cockpit procedure. I may have missed some step in the menu configuration process. I need to get the basics functioning properly before venturing on into the BFO Optimization process that might clean up the muffled sounding audio on transmit. Any helpful ideas from some of you who've lived with K2's will be greatly appreciated.

[Elecraft] Elecraft CW Net Announcement
Good Evening, The fire feels very nice today. I was simply too cold to go through another day without heat. But it does appear the forecast has some sun and warm weather in only a few days. Hopefully this will be the only fire I need in the month of August. In all the years I have lived here I have only gone a few months without a fire and those were not contiguous. Luckily I have plenty of wood left over from last year's cutting. This year's wood is ready but it is a long way from the house. Conditions were on again off again all week on twenty meters. Yesterday I made a contact but it was marginal at times. I did not realize solar minimums could be so low nor so long. I am glad that is not the only means of exciting the ionosphere. Coronal mass ejections, solar wind, even a good sized contest can all excite the ionosphere enough to allow contacts. Work on the buried power line has left me with a persistent buzz on 40 and 80 meters which has never been present before. Since the line is buried for miles in either direction I am not sure of its cause. Tonight I will pull the main breaker and start listening with a portable AM radio. Maybe I will find a source or at least a direction.

Re: [Elecraft] APF vs 10 Hz DSP, why they don't sound the same
Guy, your missing the whole point of what APF is and what is does, has nothing to do with selectivity, nothing to do with skirts at all, it is in the audio chain and there for no effect or cause with AGC Is rarely if ever used on a signal that is loud enough to copy, its mainly used for signals that are at the noise level or very weak. Narrow bandwidth can be the enemy of APF. Many times copy at wider width is the best with APF. APF never drops off the signal, it enhances it. APF = Audio Peak Filter not DSP or some other manipulation to try and fake it. To say that DSP beats APF in the proper use of APF by 10 or 20 db is proof that there is a lack of understanding of what APF does or even is. APF is not used as a selectivity tool. Its not a Q-multiplier type function, or a filter as in xtal filter or DSP filter. There were many reiterations of APF in various radios, the FT-1000 being one, and with the 1000 there were various versions even, the one that works correctly is the old original circuit, many ops had to change components to the older circuit to get the APF to function, so unless you had one of the correct versions you have not heard APF work. After watching spectrogram on a noise signal and noting a much sharper shape on 50 Hz DS as an audio peak filter, I began to wonder about some of the posts I was seeing asking for APF. What was going on? After some measurements... 1) the 50 Hz DSP bandwidth is *narrower* at the top than any APF I have used. The 100 or 150 Hz DSP is more like it. 2) the 50/100 Hz DSP has *far* steeper skirts than the APF. 3) the APF *sounds to the ear* to drop off a signal more, but that is because the signal as it moves outside the APF is still controlling the IF AGC off the APF center, holding the input to the APF constant. In the 50/100 Hz DSP the AGC opens up the gain when one tunes off the signal, giving the *appearance* of no skirts. Watching the S meter will show what is going on. This effect dissappears entirely with the AGC *off*, where the signal falls off the table on the DSP skirts as one tunes away. If one simply measures the amount of discrimination between two close signals, the 50 Hz DSP can beat the APF by 10, 20 db or more. Listening to two S9 signals only 150 Hz apart, the 50 Hz DSP can completely isolate them. In run situation, the shift and 50 Hz DSP would allow me to pick up just one and then the other by remembering their respective tones, without changing my transmit or RX reference. The SOUND of tuning across a signal with APF in a 500 Hz IF bandwidth is illusory in close signal discrimination, even if it is one's favorite analog sound. Isn't this just dumbing down a superior DSP function to sound like an analog result? And reversing myself in one of my earlier posts, the modulation pops produced by the sharp skirt drops on 10 Hz shift increments off a strong signal are annoying, and perhaps the shift can be damped just a tiny bit to remove them. __ 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

The general guideline is as little as possible. I'd suggest starting with 0 and working up to as high as a few dB only if it seems necessary. Narrow bandwidths themselves create a psychoacoustic gain effect, so you don't really have to make up for the entire loss relative to wide filters. Also, excessive gain can in extreme cases worsen the performance of DSP signal processing, such as noise reduction (NR). Finally, AGC tends to flatten signal amplitudes in general, further reducing the need for per-filter compensation. While I'm on this topic, I'd also like to suggest using a minimum of both RX and TX EQ. The '0' levels were carefully determined empirically, and in most cases the optimal values will be well below the maximum range provided. Unless you have an aural sensitivity issue in some pitch range, or a serious mic deficiency, I'd stay between +/- 6 dB. As with filter gain settings, excessive values can result in adverse interaction with the DSP. And yes, there will be per-mode RX EQ in a future firmware revision. Thanks for all the suggestions on this. 73, Wayne N6KR __ 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

The general guideline is as little as possible. I'd suggest starting with 0 and working up to as high as a few dB only if it seems necessary. Narrow bandwidths themselves create a psychoacoustic gain effect, so you don't really have to make up for the entire loss relative to wide filters. Also, excessive gain can in extreme cases worsen the performance of DSP signal processing, such as noise reduction (NR). Finally, AGC tends to flatten signal amplitudes in general, further reducing the need for per-filter compensation. While I'm on this topic, I'd also like to suggest using a minimum of both RX and TX EQ. The '0' levels were carefully determined empirically, and in most cases the optimal values will be well below the maximum range provided. Unless you have an aural sensitivity issue in some pitch range, or a serious mic deficiency, I'd stay between +/- 6 dB. As with filter gain settings, excessive values can result in adverse interaction with the DSP. And yes, there will be per-mode RX EQ in a future firmware revision. Thanks for all the suggestions on this. 73, Wayne N6KR __ 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] first post in ages W9VNE
I ordered my K3 a week ago today (Saturday) I have now used it for 48 hours. Having operated ham gear for 57 years I am just astonished how nice this little box plays. I am 98 % CW operator. I use my K2 for digital modes now. I built my K2 eight years ago. My eyesight at 71 years old suggested that I let the folks our West build this on for me. I still own a TS 930 and Omni 6+ and the K2. I have enjoyed reading the K3 instruction manual with a legal pad and writing out relevant instructions. Then returning to the rig and attempting to implement the instructions. With rare exceptions, my use has been without problems. I had to laugh to myself while reading some of the comments posted on this reflector. Humans sure like to nit pick. I had not been on this reflector for about five years. I had to get back on when I purchased K3 # 3355. The nit pickers really stand out. I wonder when they get to the pearly gates if they will complain . . .? Probably ! This is one sweet rig. Thanks to all who made it happen. Great job despite those who make suggestions (complain). The comment about the P3 should go on the right rather than the left really took the prize. Get a life OM. 73 to all the great folks at Elecraft. It also arrived one daily earlier than the 3 day UPS I paid for.

[Elecraft] Question on K3 EZ V2.0.0.3 Program
The TX CONFIG tab brings up the KAT3 bands. There is a KAT3 label at the top of the band listing. At the bottom of the screen is a statement: Click on KAT3 label to populate (FW3.03). What is FW3.03? I clicked on the label and the box for each band was populated with BYP. I had the KAT3 bypassed on each band. I hope I haven't inadvertently passed a firmware revision to my KAT3. I would appreciate it if someone can tell me about this FW3.03. Thanks.

Re: [Elecraft] K3 new V3.25 NR not so good for CW week signal
Well you can follow the convention that is mentioned I believe in the manual and use the values outlined there. Or find a steady signal on the air (or connect a signal generator) and use the AFV feature to determine the level and detect the reduction in signal level as you adjust through the filters and then you'll know how many dB delta you have between filters. ~Brett PS: The real answer to this question is to put in as little gain as it takes to make you happy and no more. The less you can use the better. On Sun, 2009-08-16 at 02:45 +, dave.wilb...@verizon.net wrote: I understand where to set the values. I'm asking how to empirically determine the value to use?

[Elecraft] APF vs 10 Hz DSP, why they don't sound the same
The DUAL PASSBAND makes a pass at providing an APF type of function where you make the DSP passband as narrow as you choose, but there's a wider passband that's 20 dB down. Undoubtedly it isn't the same shape as APF amplitude v.s. frequency, but conceptually a signal peak floating on a sea of weaker undesired signals is similar. G3XJP implementated a DUAL PASSBAND function (that terminology hadn't been invented then) in his STAR transceiver, but there the amplitude of the wider passband can be dialed to be -20, -30, -40, -60 dB. It probably isn't too big a deal to make the skirt attenuation number a user-adjustable variable but I enjoyed being able to dial it up and down as QRM changedwhich would ite up another programmable functio button. For those who suggested kicking the gain compensation up when narrower roofing filters are switched in, that's exactly what I did. I'm well aware that IF the roofing filter is setting the IMD capability of the receiver adding pre-filter gain reduces the intercept/increases IMD WHEN that IMD happens to occur, and IF it happens to fall into the passband with the desired signal. I intentionally emphasized the string of IF..WHEN..IF.. because depending upon you penchant for living in pileups, or turning the rig off on big contest weeks, a 4 dB IMD increase IF all of those things happened to occur may, or may not, be that big a deal. A post-roofing filter gain increment would not affect intercept or IMD and could be a smoothly varying increase that could conceivably be matched to a users memory of APF or Heath QF-1 function.
