[Elecraft] K1: Potential new product
This SGC page has links to 3 different reviews about ADSP2 -RadCom 11/03 -QST 01/04 -CQ May/04 I agree that 80mA is much compared to K1`s own 55mA. Elecraft KDSP2 takes 60mA (10mA in standby) and might not go in K1. Maybe an external unit is better. It can be left at home with power supply and current consumption. Experience shows that input level should be from loudspeaker line. Specs say 10mVrms min input for Lo unit, 100mVrms for Hi unit. To have a DSP Noice Reduction and AF-filter in K1 you might put this Low Power Board inside K1: http://www.sgcworld.com/ADSPProductPage.html Benny oh9nb ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] firmware update notification
Could I request that a very short notification to the Elecraft reflector (this one) be made when K3 firmware is updated, please. Just a short note like Today we released updated firmware for the K3 would be sufficient. All K3 owners will know to use their update tool to get it (or know were to look on web) and any info about the upgrade should be in the release notes (please Elecraft, do ensure info about the upgrade is well documented in the notes). So there should be no need for a long note about the update disturbing non K3 owners.

Re: [Elecraft] K1: Potential new product
If a really low power DSP could be made for the K1 and/or KX1 - say, one that consumes 10 to 15 mA from a nominal 6V supply, less from a higher voltage - which features would you be seeking?

Re: [Elecraft] Re: K1: Potential new product
The inclusion of the KX1 in this discussion is getting very close to saying that a small DSP unit should be created as an external option. There is just not room in the KX1 to add much of anything (unless the internal battery space is sacrificed. But then Lyle has created magic before, so he may be able to put one in if it has really tiny SMD technology. A small DSP board should easily be feasible inside the K1.

[Elecraft] firmware download issue
Greetings all, and FWIW: Downloaded the new K3 firmware utility v 1.1.1.7 and installed it, and then started a firmware download for the new K3 firmware 1.58/1.48 by clicking on Send all new firmware to K3. The MCU firmware downloaded OK; the DSP download ran until three bars showed in the progress indicator, and then Windows XP blue-screened, leaving the K3 disabled with a DSP error. I tried this several times and got the same result at about the same point in the download. Then I tried lowering the baud rate of the K3's serial port from 38400 to 9600, and was able to get the DSP firmware loaded, though it took a long time. Don't know what changed, but I've done several firmware downloads previously at 38400 and never had a problem. No other hardware/software changes have been done on the PC for some time. Wonder if anybody else has experienced something like this with the new version of the K3 utility? I also notice that while the download is running, the K3 display repeats new K3 utility required over and over, but often sending only a few characters and then starting over again. Don't know if this is significant, but.. 73, Van W1WCG - Original Message - From: John Hoaglun [EMAIL PROTECTED] To: Elecraft List elecraft@mailman.qth.net Sent: Wednesday, January 09, 2008 11:10 PM Subject: [Elecraft] XV222 tune-up issues Solved I figured out my tune-up issue.

RE: [Elecraft] Computer Noise ruining 20 30m
I have had good luck replacing RF noisy PC power supplies with PC Power Cooling Supplies. They seem to be well filtered. http://www.pcpower.com/index.html By the way, something I did in my shack that significantly reduced noise pickup: - Any coax line that has to do with receiving I use 100% shielded RG6 with a compression type F-connector. Where I didn't change to an F- female jack, I use an F-adapter to PL-259 or 1/4 phono. - Any coax line that has to do with transmitting I use 100% shielded Buryflex. It was amazing how much noise pickup dropped by getting rid of RG-213, RG-8X and RG-58 in the shack.

Consequently, a differential line filter often won't knock it down very much, if at all. What you need is ferrite toroids -- big ones -- around and through which you wind the power cord. In my case, the computer power supply is a 470W job in an ATX form factor, and because of the high power components, there wasn't any room in the PS case for filtering! So the RF noise from this PS was horrendous. It took TWO large ferrite donuts in series, with the ENTIRE power cord wound around them, to suppress the noise on 6M. I had bought a rather expensive differential noise filter for the line, and it did absolutely nothing. Brute-force common-mode filtering using ferrite toroids will usually cure the problem, but you may need a lot more saturability than you think. Bill W5WVO G4ILO wrote: Alan D.

Re: [Elecraft] Computer Noise ruining 20 30m
I realize this is not a specific Elecraft topic but it is in response to a request and it is on a radio subject. It would be interesting on reports on what the K3 noise blankers do on this type of noise. First of all I am no engineer but I have had some experience with this problem. I got the top of the line Carcom line filter based on suggestions on the 160 reflector and installed it right to the PC with about 1 inch of line cord and I put ferrite on that 1 inch. I knocked the noise down a bunch, I have to do some testing on a dead band to see if it is all gone but it made a huge improvement. I have to suspect your AC line filter is not a very good one OR the case is leaking. I say this because using the AC line filter seems to be the common cure that works. Fortunately my case was metal but on a lot of the new computers there is a lot of the case that is plastic. For me the problem was the worst on 160 meters. From my tests the noise was coming in over the antenna I was going to switch computer power supplies but my old ones did not provide the extra voltage line that most of the newer supplies do and that my mother board required. If I remember correctly the extra line had to do with the dual processor. It is kind of a catch 22 as the newer supplies that plug into the newer computers just are not built like they were for filtering. I am hoping someone can suggest a power supply that work with the newer computers that can be bought from places like Tiger direct etc. that is well built and quiet. One hates to buy a new supply and have the same problem and from what I can tell the odds of that happening are pretty high.. One could try and determine the noise level on a broadcast receiver and then go to a friendly computer shop and try some supplies until you found a quiet one on the broadcast receiver. That might not be all that cheap if you have to try several and take up a lot of time. It seems to me buying one that is of good design that others have not had problems with would make the most sense if one knew which one to buy. . Another approach is if someone would buy a supply and fix it and then document what supply it was and how they fixed it with filtering and toroids it would be a great service as this problem is going to be become very common as us hams update our computers. Actually I suspect they are all built about the same so what worked on one would work on all of them. A good article for one of the ham magazine but for now it could be on a web site. I will be interested in what others say. Another common problem is birdies from the Router and CAT5E cable. I am digging into that, here they seem to be on all the bands spread out. One can work around them but I want to get rid of them. Toroids seem to be one answer as a lot of routers have this problem. Again if someone knows of a router that is clean that would be an easier fix as some of the big toroids are not cheap. I guess one could buy various routers and take them back within the 30 day return period until you found a clean one but it sure would save a lot of hams a lot of trouble to know of one that is clean. I would be interested in what others say on this subject. Thanks Ed W0SD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] firmware download issue
Ouch! Please visit your USB to Serial adapter manufacturer's driver web site and see if your USB adapter drivers are out of date. If you're using the Elecraft KUSB, the Prolific web site link is in the K3 Utility's Help. I've heard a few reports of blue screen problems and all were resolved by the current Prolific drivers. The K3 Utility is using just the standard Win32 Serial I/O API, but sometimes responses don't come back when expected, and the CancelIo I need to issue is not handled well by some drivers. This doesn't show up unless there's some other communications problem. If you can, I'd be interested in the event log entry that corresponds to your blue screen event. The event viewer can be launched from a command line with eventvwr. I'll look again at the code that checks for a new utility version requirement. Maybe the end-of-year wraparound exposed a problem.

RE: [Elecraft] K3 serial cable
TX Data, RX Data, and Signal Ground are the only lines required for firmware loading.

Re: [Elecraft] Computer Noise ruining 20 30m
Great suggestion, Tony! A good way to tell if your RFI is being picked up by leaky coax in the shack or by your beam is to rotate the beam. If the noise changes amplitude during rotation, then at least some of it is being picked up by your antenna, and the only solution is to eliminate the noise at its source. This was the case in my situation, where my 6M stacked yagis are fairly close to the shack (about 35 ft), but far enough to one side that the directivity of the array had an effect. Bill W5WVO N2TK wrote: I have had good luck replacing RF noisy PC power supplies with PC Power Cooling Supplies. They seem to be well filtered. http://www.pcpower.com/index.html By the way, something I did in my shack that significantly reduced noise pickup: - Any coax line that has to do with receiving I use 100% shielded RG6 with a compression type F-connector. Where I didn't change to an F- female jack, I use an F-adapter to PL-259 or 1/4 phono. - Any coax line that has to do with transmitting I use 100% shielded Buryflex.

Consequently, a differential line filter often won't knock it down very much, if at all. What you need is ferrite toroids -- big ones -- around and through which you wind the power cord. In my case, the computer power supply is a 470W job in an ATX form factor, and because of the high power components, there wasn't any room in the PS case for filtering! So the RF noise from this PS was horrendous. It took TWO large ferrite donuts in series, with the ENTIRE power cord wound around them, to suppress the noise on 6M. I had bought a rather expensive differential noise filter for the line, and it did absolutely nothing. Brute-force common-mode filtering using ferrite toroids will usually cure the problem, but you may need a lot more saturability than you think. Bill W5WVO G4ILO wrote: Alan D.

Re: [Elecraft] Computer Noise ruining 20 30m
Yup. Lower wattage supply uses smaller componets which allows the inclusion of filter components (presumably due to more room in chassis space and components budget). It's a hypothetical model, as I've never taken one of these big boys apart, but I've seen going to a lower-power supply fix this kind of noise problem more than once. Of course, don't go to a PS that puts out less power than your computer needs. :-) I saw in another post in this thread that Antec was said to be a power supply one could count on to be less noisy. I think it has a lot more to do with the power rating than with the brand. The PS I had that was putting out so much noise was an Antec, the biggest one they made. I'm still using it, but it is brute-force choked up the yin-yang. Bill W5WVO Alan D. Wilcox wrote: SOLVED! Just replaced the 400w supply with a 300w that I had in the junk box.

Re: [Elecraft] Computer Noise ruining 20 30m
Summary: Based on the answers received and spending all morning reading on the WEB it appears PC Power and Cooling, Startec and Antec at least at the higher end have good computer power supplies. One amateur had good success curing his problem with a Startech ATX POW450Pro, two reported good results with PC Power and Cooling and one with Antec. Other possibility is Enermax but no testimonials. A lot of the information is in regards to a low DB noise level to the ear and delivering the power without a voltage drop. and not much on RFI/EMI information. The ones listed above do speak of RFI/EMI. Be sure you buy the right power supply for your computer. They are not nearly as standard as they used to be. Thanks for some great input!

Re: [Elecraft] Re: K1: Potential new product
John makes a good point. The K1 and KX1 already have much better receivers than most QRP rigs. With those rigs, the ability to make contacts is limited much more by transmitter power than by receiving capability. On the other hand, DSP noise reduction sure does reduce operator fatigue after hours of contest operation. I think NR would be the most important feature, with automatic notch and bandpass filters in the nice to have category but not as important.

Can you 'splain this a bit better Vic? Never heard of this method of timing... always worked on the baud method. First I have to reverse-engineer Wayne's code! The firmware now listens to the spaces between characters as you send. If the space is less than some fixed threshold it assumes that it is a letter space; if more, a word space. When it records what you have sent, it puts in a token that indicates either a word space or a letter space is needed. During playback, when it comes to a letter-space token it waits for the appropriate time (whatever that is); when it comes to a word-space token it waits longer. This means that while you are recording, if you wait a little bit past the threshold that it uses to decide what size space it is, it will put in a word space token. So when I send my call K 2VCO, I get K 2VCO. My suggestion is that instead of just two possibilities for spacing, there should be more. This could be implemented by creating tokens for smaller spaces, like 1/4 of a letter space. That would sound almost like a real-time recording, in terms of preserving the spacing as sent.

[Elecraft] OT - Patience, Perspective, and a Wandering Mind
I joined this list because I was contemplating purchasing a K2. I have since purchased the radio, and had more fun building it than I expected. I now have a great radio that I can fix, that I am proud of, and that is considered a standard. A standard, developed by an amazing group of people, and built by their customers. A standard which drew many current users to the list. Because of the amazing people that populate this list, I stayed, even after I had finished the rig. I marvel at the knowledge and discussions and history and experience that is here everyday, waiting for me to read. At that time the list was populated by those who had built the rigs, or were going to build them. They continue to share their experiences, their knowledge, their laughs, and their smiles. It isn't about them, it is about helping others experience what they have. If they did not have patience when they started the project, they learned about it before they were done. Many on this list have served their respective countries in admirable ways. Many have experienced life away from family and friends. A life that benefits the greater good. Many know what it is like to do their part, with little or no news and no idea what the big picture is. They know what it is like to wake up, having been dreaming about their family, only to find themselves in the dark, far from home and the ones they love. They do their part, one day at a time, and look forward to the time when they will return to home and hearth. If they did not have patience when they started to serve, they learned about it before it was over. My youngest son had the opportunity to attend a local public kindergarten. Many of the students had special needs. My son is used to this as my wife was diagnosed with Multiple Sclerosis while I was deployed for Desert Shield, and Desert Storm with the USAF. We have been married 21 years, and dealing with the disease for 16 years. She is now in a wheelchair. Thus, it was I that drove my son to school each day. Each day I had a chance to witness young children getting off of handicapped buses. They used wheelchairs and walkers. They did not know what life had in store for them, but they came through those doors in the morning with big smiles on their faces. Happy to once again be with their friends and to learn new things. These young people had patience in bulk. I learned about the K3, a few days after it was announced. I was not following the list as closely then. The radio was announced on the 27th of April, and my father passed away on the 28th. He had a great day. Many friends and family had a chance to visit, he was lively and enjoyed the day. He passed that night in his sleep. My parents had been married 64 years, and my mom is now in her early 80s and dealing with a world from a new perspective. As am I. On what would have been my father's 84 birthday, Nov. 11, 2007 (I was 12 years old before I found out they were not putting the flags out for his birthday), I ordered my K3. On January 28, 2008, my 47th birthday, my oldest son leaves for USMC boot camp, at Parris Island. He will learn a thing or two about patience. Semper Fi My point, as others have made, is to keep perspective. Learn something new everyday, share it with others that they may learn. Let those that count, know you care. Leave the world a little better as a result. Take care, and have a great day. 73 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: CW-to-RTTY with message buffers: are spaces there?
I missed some of this discussion, so I may be off track here. But I think I know what Vic means. Some message memories record in real time--you leave a long space, and it shows up in your memory the same way. But the K3 seems to be tied to a rather precise gap between letters or words. Actually, this kind of method will help point out flaws in the way a person sends. Some time back I was trying to record a CQ message in a keyer memory, and I discovered I had developed a tendency to leave a bit too much space between my next-to-last call letter and the last letter. I was sending W7AQK as W7AQ K. I probably did it for years! It was also possibly one of the reasons so many people came back to me as W7AQ, thinking I had sent the K as an invitation to transmit. In contests, etc., they weren't even waiting for the second K at the end. Now that I've been paying more intention (and it hasn't been easy getting out of that habit), I don't seem to get as many incorrect responses. The message buffers in the K3 are pretty large, so they make a pretty good recording device for recording yourself and checking on your sending technique. I know this method is kind of a pain in the butt for a lot of us, but I really like it if my messages come out like machine code. I'm not sure other methods would do this as effectively. Another thing I've been playing with a bit is sending CW and letting the K3 convert it to RTTY. If you don't move right along, with proper spacing, you get a bunch of extra garbage between characters. Being able to send RTTY without a computer is sort of a gee whiz feature, but it's been fun playing with it.

From a practical point of view, giving up some degree of flexibility - perhaps a limited number of bandpass filters and a fixed (in set-up) center frequency - would probably be acceptable. With DSP it might also be reasonable to give up some degree of performance (ultimate rejection) in the crystal filters as they would be similar in function to the roofing filter in the K3. 73, ...

[Elecraft] DSP for KX1 and K1
The nature of the KX1 (and the K1, hope to build one of those soon) would argue for a very low power, simple DSP. Since they are CW only rigs, Autonotch doesn't make sense to me (wouldn't it attack the CW note you are trying to hear?). Also, the KX1 built in crystal variable filter works FB for me. So, I think my preference would be a denoiser only - I'm sure you could fit that in the K1, maybe in a KX1. 73, Bill K4DXU KX1 # 702 K2 # 5540 K3 # 00175 Lyle Johnson wrote: If a really low power DSP could be made for the K1 and/or KX1 - say, one that consumes 10 to 15 mA from a nominal 6V supply, less from a higher voltage - which features would you be seeking?

For those who would like to use the large VFO A knob as if it were RIT, there's a setup just for you. Once you have your base frequency (or RUN frequency in a contest) TAP AB to send the VFO A frequency to VFO B. Then place the K3 into SPLIT mode. Your TX frequency will not change, but now you can tune your RX frequency with the VFO A knob to tune in those stations calling who are slightly off frequency. In the CONFIG menu there's also a BA function that you can assign to one of the programable buttons. This feature allows you to pick up your TX frequency from VFO B to match your RX frequency on VFO A. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 Operating Tip: How to do RIT (sortof) with the BIGknob
That's just how the K2 works too. I run split 100% of the time and almost never touch RIT with either the K2 or K3. For those of us who cut our teeth in Ham radio on separate transmitters and receivers, it works just like they did. 1) Tune around and find the frequency you want to transmit on. It might be someone calling CQ or a clear spot to make a call. 2) Hit A B to load the frequency you've selected by tuning around into VFO B. VFO B sets the xmit frequency, just like when we set our Tx VFO on the Rx frequency, only a lot faster. Now you can continue to tune around with the big knob, but whenever you xmit it'll be on the previously selected frequency in VFO B. At any time you want to move the TX freq to the one you're listening to, just tap AB again. If you're working a pileup or other situation where I am listening and transmitting on different frequencies, pushing REV allows me to peek at my xmit frequency to make sure it's still clear. (Of course that'll be even easier when the Subreceiver is available!) For me it's not like doing sort of RIT with the big knob, it makes RIT unnecessary. Ron AC7AC -Original Message- For those who would like to use the large VFO A knob as if it were RIT, there's a setup just for you. Once you have your base frequency (or RUN frequency in a contest) TAP AB to send the VFO A frequency to VFO B. Then place the K3 into SPLIT mode. Your TX frequency will not change, but now you can tune your RX frequency with the VFO A knob to tune in those stations calling who are slightly off frequency. In the CONFIG menu there's also a BA function that you can assign to one of the programable buttons. This feature allows you to pick up your TX frequency from VFO B to match your RX frequency on VFO A. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
