Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I updateTheSoftware?
Most 3-500 based amplifiers with 2800 V (no load) on the plates require 120 Watts or so for legal limit output. That's about 11 dB gain. Even with 3 x 3-500s in my LK550 and 2,900V no load, I only need about 25-40W input depending on band to reach our legal limit: 500W. Which is plenty, way too much in fact for the digital modes. Part 97.317(a)(2) limits the maximum gain to 15 dB (approximately 50 W drive for 1500 W out). Not in NZ. Is there really a max gain regulation in the US? How quaint! The extra 10 to 20 watts of drive makes a difference for those who have SB-220, TL-922, AL-82, AL-1300, AL-572, etc. amplifiers. It can mean another 200+ W output. ... The difference will be small in pure signal strength terms but sure the operator's confidence is improved. A cheaper option (as used by certain CBers) is to tweak your power meter to read high. Seriously, though, a bit more attention to operating skills and maybe a little investment in your antennas and feeders will eclipse the QRO option every time. #1 DXing tip is simply to be very active and listen hard. #2 is to save up those tenths of dBs you get for free by eliminating unnecessary coax connectors, and indeed unnecessary coax. Someone should start giving out 0.1dB savings stamps and a DXers' collector's card. 73 Gary ZL2iFB __ 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] Will I Lose the 120 Watt Max If I update TheSoftware?
Unfortunately the 3rd order IMD of a typical 12 Volt PA is barely acceptable when operating at 100 Watts let alone pushing 120 Watts from a K3. The K3 would output 120 Watts, or 110 Watts in later firmware, and yet is recommended by Elecraft to run 100 Watts max on SSB. Running a K3 at 25 Watts improves the IMD on SSB by around 10 dB. My Acom 1000 amplifier runs the UK limit of 400 Watts with less than 30 Watts drive. For amplifiers needing 120 Watts of drive you need a higher power transceiver than a K3, at least that way you stand a chance of having a clean signal on SSB. 73 Dave, G4AON K3/100 #80 -- Most 3-500 based amplifiers with 2800 V (no load) on the plates require 120 Watts or so for legal limit output.

[Elecraft] K3 Feature Idea
Not too long ago there was some debate about the Fast QSY function that can be used if you set VFO OFS = 1. There were those who feel that the fast QSY function should *not* clear the LSB's so that if you use it (or perhaps accidentally bump it) you have an easier time getting back to the frequency that you were previously on. However there are those who have grown accustomed to the M.CH knob on Kenwood rigs that allow for 1Khz movement but it *does* clear the LSB's and allows you to tune the band in a channelized fashion. Personally I kinda wish that we'd use the band in a more random fashion and less like CBer's but thats just me... ;) Any way I had a thought. Being that the CLR button has no function when the user is simply listening with RIT and XIT off why not have that button clear the 3 LSBs. That way if you want the first scenario mentioned above you simply grab the knob and crank away. However if you prefer the second scenario you only have tap that CLR switch. This is a very simple action and one can hit this button in the same motion while reaching for the knob. Anyone have thoughts? ~Brett PS: Sorry for more nit picks on the K3 guys but honestly I think we're at this level now... For me the K3 works wonderfully. Granted I know that with this group out here there will be more great ideas and some more big exciting firmware releases are on the way!

[Elecraft] Re： RadCom, Chinese K1?
Hello David, The ham radio market in China is something like Japanese market 25 years ago. While ham population has been declining in most part of the world, the number of ham in China is in fact increasing. China is just like a world factory and manufacture products from high end to low end. Of course, you may say that some of them are copy cat. However, it is a kind of evolution proces like Japan in the 50-60's. I have no idea about the quality of this Chinese K1 but I would guess its price could be just 1/4 of an Elecraft K1 in China. Hong Kong is just the southern door of Mainland China. Within one hour travelling distance, we can reach the silicon valley of China, Shenzhen and there are varieties of Electronic products at 1/3 of the US price. As you may be aware there are now Chinese made V/U handheld at price of 1/3 of the Japanese one. Initially, the quality of these Chinese H/T is not up to standard but I find them in fact keep on improving. Back to Elecraft, as we are aware, material costs of K2 and K3 etc should not be great. All we paid for is the design concept and excellent support service from Elecraft. I do not try to put myself into the debate of intellectual rights. The reality is that there are always Chinese products with similar function but at 1/4 or 1/5 of the price. You may not like it but within a second, you may think about it though you eventually disregard it. As mentioned before in this reflecter, Li-ion battery in China is now so cheap that it is only 1/5 of the price in US. I once thought of using them in the KBT2 of my K2. However, like most of you in this reflector, I have doubt on the quality of these cells and drop my idea. I do not know how long I would insist on thinking like that because I find the quality of these cells keeps on improving. 73 Johnny VR2XMC from Hong Kong 寄件人﹕ David Lankshear d...@lanks.plus.com 收件人 Elecraft@mailman.qth.net 傳送日期﹕ 2009/9月/21 (星期一) 8:47:44 PM 主題： [Elecraft] RadCom, Chinese K1?

If you want good quality electronics, it probably will come from China. The K1 does not come from China, but I expect many of the components do. My PC was made in China - fastest I have ever had and cheapest too. My TV came from China (ditto) my mobile phone was made in China. and so on. If there is an Elecraft in China I wish them every success and I expect Elecraft will too as long as they are not making direct copies.

Re: [Elecraft] K3 Feature Idea
I plan to change VFO coarse tuning in general so that it quantizes. Tapping CLR to accomplish this strikes me as further control overloading, which I want to avoid. Besides that, CLR clears the RIT offset even if RIT is off. Wayne Sent from my iPhone On Sep 21, 2009, at 4:12 AM, Brett Howard br...@livecomputers.com wrote: Not too long ago there was some debate about the Fast QSY function that can be used if you set VFO OFS = 1. There were those who feel that the fast QSY function should *not* clear the LSB's so that if you use it (or perhaps accidentally bump it) you have an easier time getting back to the frequency that you were previously on. However there are those who have grown accustomed to the M.CH knob on Kenwood rigs that allow for 1Khz movement but it *does* clear the LSB's and allows you to tune the band in a channelized fashion. Personally I kinda wish that we'd use the band in a more random fashion and less like CBer's but thats just me... ;) Any way I had a thought. Being that the CLR button has no function when the user is simply listening with RIT and XIT off why not have that button clear the 3 LSBs. That way if you want the first scenario mentioned above you simply grab the knob and crank away. However if you prefer the second scenario you only have tap that CLR switch. This is a very simple action and one can hit this button in the same motion while reaching for the knob. Anyone have thoughts? ~Brett PS: Sorry for more nit picks on the K3 guys but honestly I think we're at this level now... For me the K3 works wonderfully.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
But that's still only a fraction of 1 dB gain in signal - not detectable on most S-meters. RF power is one place where more yields diminishing results. The increased signal at a receiver when going from 10W to 100 watts output is exactly the same as the difference between 100 and 1000 watts, but that extra 900 watts costs a lot more to produce than the 90 watts.

Re: [Elecraft] [K3] K3 ergonomics
I use the BAND button without even thinking about it when I only need to go up or down one band, which is often. Along with the MV direct band selection I would say that on average it takes me about 1.25 button pushes to switch bands, hahah... So, one-push dedicated band buttons aren't on my wish list. However, I do think the BAND button could be made to be a lot more versatile. I'd like to have it jump among a contiguous range of slots in the programmable frequency memories (10-99). Then I could program as few or as many bands as I wanted, in whatever order I wanted, including non-ham bands.

Re: [Elecraft] [K3] Fw: Non Amplified D104
Did you use the K3's MENU:MIC SEL option to choose high gain for the microphone input? It sounds like the element is good, but they were designed for very high impedance inputs. A very simple one-transistor amplifier would fix that and provide a better impedance match for modern rigs. Indeed, impedance matching was one of the major functions of the amplifier built into the base of the later D104's. Crystal elements like the D104's were appreciated for their relatively high audio output which made up for their being very fragile - easily damaged by a hard knock, high temperatures and moisture. If it's an old D104 whose element has survived all these years, it's likely a ceramic element. Ceramic elements replaced the crystal elements in most microphones starting shortly after WWII. They are relatively rugged but provide somewhat lower output. It sounds like your ADI rig had more mic gain available than the K3. Has the mic cord been replaced? I tried that for a buddy who had a D104 with a badly worn cord. Didn't work at all using modern shielded microphone cable. The problem was traced to what's considered a shield these days - a few strands of bare wire wrapped around the center conductor! They can get away with that today for most applications because of the lower impedance of modern dynamic microphone inputs, but it's hardly a shield. Using it with the high-impedance D104 element it picked up hum and lots of other noises like the fan noise you mention. I fixed my buddy's problem by throwing away the mic cord and using RG-174 coax - the miniature stuff - that has a decent braid shield around the hot conductor. FWIW, the D104 has a starring role in the new film about Amelia Earhart, Amelia. It makes lots of appearances in the hands of people at ground facilities talking to her in the air. Ron AC7AC -Original Message- I tried a non amplified D104 and it was not good at all. The audio was real low when the mike was at 60. It had a slight fan noise and I had no fans running. The mic was wired up right because when I put it back on my ADI radio it worked well. My ADI radio hand mic works on my K3. ADI and Kennwood wiring is the same. Now the non amplified D104 is a museum piece in the shack. __ 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] Fw: Non Amplified D104
Did you use the K3's MENU:MIC SEL option to choose high gain for the microphone input? Good advice from Ron. After checking that, and assuming the mic is relatively old and its past quality-of-life unknown, I would consider replacing the D-104's mic element with a similar crystal element from Mouser: http://www.mouser.com/catalog/specsheets/KT-400023.pdf Price in small quantities is USD $4.77. If you use a single-transistor FET buffer, be careful of the various designs and mods seen on the web. Some utilize unnecessary components at best, and performance-degrading parts at worst. If an existing 2-stage Astatic buffer is used, one can place a resistor in series with the mic lead, 1 megohm in value and make up the gain with the amp's level pot although it may become unstable and certainly noisier than a well-designed single-stage FET circuit. Either circuit can be powered from the K3's mic connector through a current-limiting resistor. The existing input Z of the Astatic pre-amp calculates to ~ 470K-ohm and although it may seem high, it's just not high enough for a crystal element to achieve a reasonably flat response down to 80-90 Hz -- the first fundamental of most male voices. My D-104 achieves this with the K3 in ESSB mode, although I'm not sure if all of the extended low-end can be captured in the K3's default SSB Tx setting.

If this Chinese K1 is simply another ham's design of a QRP rig, that's fine. If it's a copy of another company's radio, it's theft, plain and simple. 73, Jim Brown K9YC __ 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] Ren+s( RadCom, Chinese K1?
For anyone interested in a comparison the Chinese transceiver manual (including circuit diagram) can be downloaded from: http://www.hamradio.co.uk/pdf/HB-1A.pdf It's similar to the KX1 and priced at 250 GB Pounds, the KX1 costs approx 264 GB Pounds including postage import handling and tax, at the current exchange rate. Your mileage may vary, as they say, but it just doesn't compare to a KX1 on cost, accessories, support, or anything else I can see. 73 Dave, G4AON __ 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

Those that transmit extended HF response are selfishly using more bandwidth and generating more QRM to their fellow hams. Well, yes -- in the middle of a crowded band or contest or whatever. No one sense there should be a lack of common sense about what constitutes good operating practice. But good operating practice is very dependent on time and place.

A major difference today is that back then we simply rolled off the upper frequencies with the very simplest audio filtering - often just using bypass capacitors in the audio stages that tended to attenuate highs. The result was substantial audio energy being transmitted well above 3 kHz. Nowadays we have the filters to limit high frequencies much better. I understand that there's good evidence that, when digging for a signal in the noise, a lower upper-frequency limit can provide better communications (provided the lows below 300 Hz or so are also attenuated). It's a matter of concentrating the finite amount of RF into the most effective part of the audio spectrum. I find such pinched audio tiring to listen to for any amount of time, and losing the higher frequencies makes many phonemes harder to decode, perhaps because of the US Army's special gift to me (tinnitus from firing too many rounds from my M1 rifle parked next to my ear - our steel helmets don't come with ear protectors). Perhaps before long we'll start to see computer generated speech that is optimized for minimum bandwidth and maximum intelligibility rather than continue to use our clumsy, inefficient and highly variable biological speech mechanism called lungs, throat and mouth ;-) After all, we've largely dispensed with that personality in CW since most Hams have dumped their mechanical keys for keyers that compensate for most variations in fingers movements or even to a keyboard that eliminates any chance of human variability or inefficiency while pounding brass.

By cutting through I am specifically talking about speech intelligibility, and thanks to my background in pro audio and sound reinforcement, it is a topic I know quite a bit about. Sound systems that must provide speech intelligibility in difficult environments are carefully designed to limit the low frequency response. Three reasons. First, the lower octave bands make very little contribution to speech intelligibility. Second, the lower octave bands are most subject to the effects of reverberation. Third, the lower octave bands burn power that could be better used on the spectrum that does provide intelligibility. The only part of the above that doesn't apply directly to radio communications is reverberation. Note that no one is recommending excessive modulation or processing, which certainly does degrade intelligibility. The K3 can very easily be set up to limit the audio bandwidth, shape it to provide pre-emphasis for the bandwidth lost due to IF filters, and provide dynamics processing (compression). And it sounds VERY good when done properly. I'm coming at this from the perspective of an audio professional and a radio professional. I'm a Fellow of the Audio Engineering Society, passed my First Phone in 1959 and began working in broadcasting soon thereafter.

However there are those who have grown accustomed to the M.CH knob on Kenwood rigs that allow for 1Khz movement but it *does* clear the LSB's and allows you to tune the band in a channelized fashion. Personally I kinda wish that we'd use the band in a more random fashion and less like CBer's but thats just me... ;) Any way I had a thought. Being that the CLR button has no function when the user is simply listening with RIT and XIT off why not have that button clear the 3 LSBs. That way if you want the first scenario mentioned above you simply grab the knob and crank away. However if you prefer the second scenario you only have tap that CLR switch. This is a very simple action and one can hit this button in the same motion while reaching for the knob.

Re: [Elecraft] K3 Feature Idea
Sorry -- geekSpeak :) Suppose the VFO were tuned to, say, 7040.23, in CW mode. Further assume your CONFIG:VFO CRS menu parameter is set to 1.0 kHz (i.e., your COARSE tuning step is set to 1.0 kHz in CW mode). If you then go into COARSE mode and move the VFO up one tic, you'll get 7041.23 with present firmware. In the future you'll get 7042.00: quantized to the nearest quantum which in this case is the next even multiple of 1.0 kHz. The same will apply if you have the RIT/XIT offset control enabled for use as VFO coarse tuning when it's not being used for RIT/XIT (see CONFIG:VFO OFS). The control will be quantized just like the VFO when it is in COARSE mode. The VFO already quantizes with smaller tuning increments selected (e.g. 50 Hz).

A clean square sided audio response that passes 150-200 Hz to 2800-3000 Hz (2.8 KHz bandwidth) with a notch between 750 and 1100 Hz and a response that rises at 3 - 6 dB per octave between 1000 and 3000 Hz is a thing of joy to hear. Such a response is very efficient use of bandwidth, is easy to understand but not harsh and almost natural sounding. Those who boost bass below 150-200 Hz do nothing but make their audio muddy - particularly if the bass boost is followed by any compression/clipping - and difficult to tune. I'd very much like to see the Elecraft equalizers modified to match 10 of the ISO 2/3 Octave standard (63, 100, 160, 250, 400, 630, 1000, 1600, 2500, 4000 Hz) frequencies. By having a band centered a 1000 Hz, it is possible to cut the interformat band (significantly reducing background noise in an area lacking any voice energy), to cut audio below even the most low pitched male voices (63 Hz), provide a smooth rising characteristic (1/1.6/2.5K) and sharply limit the high frequency (4K) components that cause adjacent channel interference without contributing to communication efficiency. In addition, control over the two groups (100/160/250/400 and 1600/2500) provide the ability to balance the high/low formats compensating for variations between strong/weak voices. 73, ...

Such a response is very efficient use of bandwidth, is easy to understand but not harsh and almost natural sounding. Those who boost bass below 150-200 Hz do nothing but make their audio muddy - particularly if the bass boost is followed by any compression/clipping - and difficult to tune. It's natural if all of your friends are parrots. This is ridiculous. No one here is advocating 20Hz-20Khz as a regular option on the ham bands. (Well, you would if you really wanted to sound like YOU instead of a parrot, but that's another issue). There is nothing natural sounding about what you propose. Unless you have really bad hearing, or or just so used to thinking that nothing sounds better than a KWM-2 that anything else doesn't work. All of this efficiency stuff is smokescreen. You sound like a human being or you don't. You can understand (out of context) what the guy on the other end is saying or not. No one here is advocating using 20Hz to 20Khz transmit bandwidth in the context of good amateur practice. So why is there so much hard core insistence than we should have bad audio ALL of the time.

Re: [Elecraft] K3 Feature Idea
If I interpret the geekSpeak correctly, this looks like rounding off the frequency whether the user wants it or not. Coarse tuning rounding off when using the main tuning control is not a problem, but when the RIT/XIT tuning control is configured for coarse tuning works just fine for me the way it is, it is very similar to the implementation from Kenwood on the TS570 and TS480. Rounding off the frequency when using the RIT/XIT for tuning is a pain, as an accidental move of that control means you can't return in a couple of clicks to your original frequency. The K3 interface already has awkward compromises (accidentally going up or down a band when turning VOX on, QSK on, not being able to spin through multiple memories while listening to each one across different bands, etc.) lets not make it harder to use. 73 Dave, G4AON K3/100 #80 - Suppose the VFO were tuned to, say, 7040.23, in CW mode. Further assume your CONFIG:VFO CRS menu parameter is set to 1.0 kHz (i.e., your COARSE tuning step is set to 1.0 kHz in CW mode). If you then go into COARSE mode and move the VFO up one tic, you'll get 7041.23 with present firmware. In the future you'll get 7042.00: quantized to the nearest quantum which in this case is the next even multiple of 1.0 kHz. The same will apply if you have the RIT/XIT offset control enabled for use as VFO coarse tuning when it's not being used for RIT/XIT (see CONFIG:VFO OFS). The control will be quantized just like the VFO when it is in COARSE mode. The VFO already quantizes with smaller tuning increments selected (e.g. 50 Hz). So quantizing COARSE increments would be more consistent with present behavior. 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] Elecraft email List Official Guidelines [Sept 2009]
Elecraft Mail LIST GUIDELINES [Sept. 2009] For those of you who are new to the list, (and for those of us who have rapidly failing memories..), here is a quick list of things to remember when posting to this list. Please save this for future reference. The most important thing to remember is that this is only a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share troubleshooting ideas etc. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft@mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1...@arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w...@arrl.net from your physical address of j...@aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and monthly afterwards.) 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. Always delete -everything- from the prior post except what is necessary to keep your reply in context. Most copied messages can be reduced to one or two sentences to retain context. Remember to delete the email list footer from the previous post and especially avoid copying a long posting and adding 'Me Too!' or something similar. As the number of users on this list grows (over 1500 now) we need to work to minimize information overload... If a reply is -not- of interest to the list, just reply directly to the posting party. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With close to 3,500 list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building and troubleshooting their kits. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** [NEW] When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line. Examples: Subject: [K3] Filter Options Subject: [KX1] How to use ped portable? Subject: [XG2] Wow! Its a big help. 5. *** IMPORTANT - PLEASE KEEP ALL POSTINGS CORDIAL. Restrain the urge to email someone admonishing them about a posting. The last thing we want to do is to scare anyone off the list. Overly aggressive postings and negative comments about other posters only serve to scare away new potential list members. Waiting over night before hitting 'send' really helps to put things in perspective.. ;-) If you have a complaint about someone or a thread please email it directly to me ( eric(at)elecraft.com ) and I'll address it. 5a. Please do not post publicly or privately asking people to stop a particular thread, no matter how long, off topic or repetitive it
[Elecraft] K3 - Quantizing...
Greetings, As a very active CW op, I would find what Wayne has just mentioned a backward step. Quite often I find occasion to ask DX to move up 1 when they call me as I finish a QSO I had initiated by responding to a CQ - in other words - I need to move my intending QSO away from the other stations' frequency. It's really handy to be able to go up 1 or 2 etc exactly. Rounding off the next KHz would totally defeat the purpose for me; or am I missing or misinterpreting something here? By the way, I'm sure that the Kenwood rig could be told whether or not to quantize with its' equivalent up 1 button as I would call it. 73, Tony, ZL2AGY K3 #2867 __ 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

It's really handy to be able to go up 1 or 2 etc exactly. Rounding off the next KHz would totally defeat the purpose for me; or am I missing or misinterpreting something here? As I recall, the TS850 only quantized (rounded off) the frequencies when using the rapid QSY function (i.e. the M.CH/VFO.CH knob). QSYing with the VFO knob or RIT/XIT stepped as normal in whatever step rates it was set to with no rounding. Quantizing was useful to get quickly to rounded frequencies, such as the NCDXF beacons on 28.200 21.150 etc. Also for rapid band changes when chasing mults in contests (QSY 7035 NOW). By the way, I'm sure that the Kenwood rig could be told whether or not to quantize with its' equivalent up 1 button as I would call it. Maybe a config setting - I can't remember. But the K3 function will presumably be a configurable option too so those who want to quantize can and those who don't needn't. Actually an up 1 split function (e.g. if A=B, then SPLIT would automatically add +1 kHz on B since there's no point in 'splitting' on the same freq) would be neat for us CW DXers - maybe an up X button where X is a settable parameter would suit the SSBers too? 73 Gary ZL2iFB ZM4G G4iFB (www.G4iFB.com) K3#2887 K2#1770 Forget the Internet.

Re: [Elecraft] K3 Feature Idea
Wayne, In the spirit of not desiring magic buttons, I can say that if I want that behavior on my radio, I will set the dial (with VFO A knob) to .00 and then I can use the RIT knob to move in 1 kHz increments. In other words, I like the behavior as it is now. If I am tuning the SSB portion of the band, yes, I will quantize the low order digits manually, but if I am tuning the CW portion, automatically quantizing the low order digits is not as great an idea - I may want a particular offset from 00, so let me do it myself if I desire, but please do not force it on me. 73, Don W3FPR Wayne Burdick wrote: Sorry -- geekSpeak :) Suppose the VFO were tuned to, say, 7040.23, in CW mode.

[Elecraft] Upcoming K3 features
Wow! I go off-line for the weekend and everyone goes crazy. Must have been a slow news weekend, or just poor propagation on HF.. :-) I see there is a lot of misunderstanding out there on what is already here, or is coming soon, so I'd like to clarify a few items. 1. TX/RX EQ = OFF in digital modes will be implemented in within the next couple of releases. 2. RX active while manually tuning through memories will also be implemented shortly, within the next couple of releases. 3. AM Sync is actively being completed. We have an internal version in the test lab and we should have a beta version out soon. It turns out this was not a simple task. 4. The TCXO-1 actually turns out to meet 0.5 ppm over the commercial temp range. We were over conservative in our initial public specs on this item - It already met this without additional calibration. We are also testing a future version of K3Utility that lets you enter temp correction values for a further increase in accuracy, but I'm not sure how quickly this will be released. As a general comment, we have a very specific prioritized list of items that we are working on for the K3. some we've talked about, some we haven't. And some are internal items to improve manufacturing yield, etc. We certainly do pay attention to the list comments and requests, but we do not jump back and forth each week trying to meet new requests at the expense of others. Some times it conveniently works out that we are already about to implement something requested on the email list, or that it is trivial to add quickly. That's why you might see it pop up shortly after a list discussion. Also, while it may seem like we have not responded to your specific request, it does not mean we have ignored it. We get so many varied requests that there is no way to satisfy all of them, but we do write them down and we periodically meet and re-prioritize those items that are doable. Wayne and I both feel strongly that a lot of our success is due to our company's responsiveness to your product ideas and requests. We see our major products, like the K3, as a continually evolving and improving in response to customer feedback. We're constantly amazed at the breadth of applications that you are using the K3 for. From Rag Chewing, DXing, QRP, Contesting, SO2R, Moon-bounce and Data modes to ESSB, each user community has a wide range of uses and requests. We can't do everything, but we do make careful attempts to add the most useful requested features over time. We'll never meet everything requested - there just isn't that much development time or microprocessor memory available. But we'll strive to make the K3 as good as it can be. Its impossible for us to guess the many ways our products, like the K3, will get used up front, so we make our best effort to get a good core set of features into the product at initial release, and then we iterate and improve in response to your feedback over the life of the product. We hope that approach keeps our products fresh and fun to use over their life, and that it keeps us ahead of our competition :-) 73, Eric WA6HHQ . __ 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

Hi Wayne: With regard to the VFO coarse tuning. I would use it if it was disabled when the VFO A LOCK function is active. At the present time, the knob is not locked out.

[Elecraft] K3 EZ software
Hi Is there a version out there that does NOT require .NET on the computer? I will not allow .NET to be installed on my machine, hence my question.

[Elecraft] K3 EZ and .NET
Ok, the reason for me not wanting the .NET software is as follows: 1. The program will run off line for a limited time and then want to go to Microsoft for updating. 2. It is not a particularly fast program and has caused a few issues in the past. Some folks have suggested that it is easier for software developers to use .NET to write programs etc. In my case, I run my K3 from my motorhome in remote areas that have no access to the internet for me and therefore I do not want web dependant programs on my computer.

[Elecraft] using K2 in ARES
Hello Group, I would like to enquire any of you has the experience using K2 in ARES. QRP K2 is handy and with minimal current consumption. With KAT2, a HF portable station can be set up right the way with a piece of random wire. By replacing the lead acid battery with 3300mAH Li-ion cells, the weight of K2 will be much reduced. Do I miss anything in considering using K2 as a ARES HF rig? Your comments and advice are much appreciated. 73 Johnny Siu VR2XMC Yahoo!香港提供網上安全攻略，教你如何防範黑客! 請前往 http://hk.promo.yahoo.com/security/ 了解更多! __ 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: IF output buffer gain modification
I've just gone through the last 800 or so recent reflector messages (I haven't downloaded my email in a few days), and not a single one was devoted to this hardware modification. I have a couple of questions: 1. What is this mod for? I'm assuming it's for the Elecraft panadaptor, but why do we need to mod the K3? Couldn't the IF output be amplified by the panadaptor? I'm not really comfortable cutting stuff out of my 4 thousand dollar investment. 2. If I do decide to buy the panadaptor, can Elecraft perform this modification for me if I send the radio back? I've already done most of the hardware mods, but SMD stuff I refuse to deal with. 73 de James K2QI __ 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

From Rag Chewing, DXing, QRP, Contesting, SO2R, Moon-bounce and Data modes to ESSB, each user community has a wide range of uses and requests. We can't do everything, but we do make careful attempts to add the most useful requested features over time. We'll never meet everything requested - there just isn't that much development time or microprocessor memory available. But we'll strive to make the K3 as good as it can be. I can envision the day that you will be able to boot your K3 with different FW, related to the mode of operation (as listed above) you desire. FW would be stored on your computer and loaded via utility. So, if you wanted to do a CW contest, load the CW version, Data Modes, load data mode FW, Hi-Fi AM, and so on. It would only take a few minutes and give you a rig suited to any mode of operation. Sure could save a bunch of memory. You could even keep a FW similar to todays, just not refined in all modes.

I'm not really comfortable cutting stuff out of my 4 thousand dollar investment. In some circumstance, the IF output level is weaker than the signal at the antenna connector, so the S/N suffers. This mod adds gain back in the appropriate location so the attached panadaptor will be able to display signals as weak as you can hear on the K3 itself. 73, Lyle KK7P __ 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] RIT and VFO-A was (K3 Feature Idea)
Wayne, Maybe it would be possible to have the best of both worlds. Have the firmware remember the frequency in VFO A. With your example of VFO A at 7040.23, have a clockwise turn of the RIT knob move the frequency to 7041.00, 7042.00, 7043.00 etc. Reversing the direction of the RIT knob would result in, 7042.00, 7041.00, 7040.23 , 7040.00, 7039.00 etc. If you move the RIT by mistake, all you have to do is rotate the control until you see an odd frequency (*.xx). That will be your original VFO A frequency. Any rotation of the VFO A knob or band change allows a new reference frequency to be stored with the next RIT knob rotation. Most SSB contacts and nets are on even KHz so the RIT can be used to quickly get on an even frequency but it would not work to return to the original VFO A frequency unless some other form of announcement is used (a beep perhaps!). This is just food for thought. 73, Tony Fegan VE3QF Wayne Burdick wrote: There will be a menu entry.

If I am tuning the SSB portion of the band, yes, I will quantize the low order digits manually, but if I am tuning the CW portion, automatically quantizing the low order digits is not as great an idea - I may want a particular offset from 00, so let me do it myself if I desire, but please do not force it on me. 73, Don W3FPR Wayne Burdick wrote: Sorry -- geekSpeak :) Suppose the VFO were tuned to, say, 7040.23, in CW mode. Further assume your CONFIG:VFO CRS menu parameter is set to 1.0 kHz (i.e., your COARSE tuning step is set to 1.0 kHz in CW mode). If you then go into COARSE mode and move the VFO up one tic, you'll get 7041.23 with present firmware. In the future you'll get 7042.00: quantized to the nearest quantum which in this case is the next even multiple of 1.0 kHz. The same will apply if you have the RIT/XIT offset control enabled for use as VFO coarse tuning when it's not being used for RIT/XIT (see CONFIG:VFO OFS). The control will be quantized just like the VFO when it is in COARSE mode. The VFO already quantizes with smaller tuning increments selected (e.g. 50 Hz). So quantizing COARSE increments would be more consistent with present behavior. 73, Wayne N6KR e NF4L Wayne Burdick wrote: I plan to change VFO coarse tuning in general so that it quantizes. __ 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

By cutting through I am specifically talking about speech intelligibility, and thanks to my background in pro audio and sound reinforcement, it is a topic I know quite a bit about. Sound systems that must provide speech intelligibility in difficult environments are carefully designed to limit the low frequency response. Three reasons. First, the lower octave bands make very little contribution to speech intelligibility. Second, the lower octave bands are most subject to the effects of reverberation. Third, the lower octave bands burn power that could be better used on the spectrum that does provide intelligibility. The only part of the above that doesn't apply directly to radio communications is reverberation. Note that no one is recommending excessive modulation or processing, which certainly does degrade intelligibility. The K3 can very easily be set up to limit the audio bandwidth, shape it to provide pre-emphasis for the bandwidth lost due to IF filters, and provide dynamics processing (compression).

Re: [Elecraft] [K3] K3 Audio Response - Version 3.33 Firmware
It's natural if all of your friends are parrots. It is far from a parrot and light years ahead of the muddy base rumble from the overly boosted, compressed and clipped 50-150 Hz that passes for audiophile product these days. This is ridiculous. No one here is advocating 20Hz-20Khz as a regular option on the ham bands. Even 20 Hz to 5 KHz is absurd on the amateur bands. More than 90% of all transceivers have IF filters that on their best days will pass 3 KHz ... most are less than that. To transmit a signal wider than 2.8 KHz (200 to 3200 or 150 to 3150 Hz) to 3.2 KHz (150 Hz to 3350 Hz) anywhere other than on 10 Meters for a local QSO is an absolute exercise in ego self-gratification and intentional QRM to other users of the band. Like K9YC, I have more than little professional familiarity with good audio. I spent my entire professional career in in the broadcast and recording industries and started out doing more than enough live recordings, talk shows, and live event audio to know what constitutes good and excellent audio for all purposes. More importantly, I know the difference between audio designed to go to a digital recording media and audio that needs to work through a band limited channel. So why is there so much hard core insistence than we should have bad audio ALL of the time. Nobody is insisting that we should have band audio, ever - but both Jim and I are saying that wide bandwidth and good audio are NOT the same. With the proper choice of passband, equalization, and judicious use of clipping/compression, one can have good audio in a reasonable bandwidth ... AM (5-7 KHz) or FM (12-15 KHz) broadcast audio bandwidths are not necessary or appropriate for amateur use at HF. -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Grant Youngman Sent: Monday, September 21, 2009 5:58 PM To: Elecraft List Subject: Re: [Elecraft] [K3] K3 Audio Response - Version 3.33 Firmware On Sep 21, 2009, at 4:14 PM, Joe Subich, W4TV wrote: A clean square sided audio response that passes 150-200 Hz to 2800-3000 Hz (2.8 KHz bandwidth) with a notch between 750 and 1100 Hz and a response that rises at 3 - 6 dB per octave between 1000 and 3000 Hz is a thing of joy to hear. Such a response is very efficient use of bandwidth, is easy to understand but not harsh and almost natural sounding.
