[Elecraft] K2 Bandscope update
I've updated the little bandscope I wrote to fix the problem with unexpected messages if the K2 had previously been using another CAT program. I've also made some improvements in operation so you can more easily continue scanning the same band segment after clicking on a signal. For those who weren't sure, it REQUIRES a KIO2 and hence it's no use for any radio except a K2. And yes, it's a Windows program. Nearly 100 people downloaded the original as of midnight last night when the web stats were generated. I'd be interested in some feedback on it, particularly from those who have one of the commercial programs with a bandscope to compare it with. Those programs appear to use audio, via the sound card, to generate the bandscope. Those programs aren't available for free trial, so I can't test them to see for myself. As I wrote yesterday, this was primarily an experiment to see how to make a bandscope for the K2. It seemed to me that if I used audio, then in order to be sure the audio the program was hearing was coming from the frequency it set, the program would have to scan the band very slowly. This bandscope scans 100 1KHz segments in about 5 seconds, but it takes an S meter reading at each point and uses this to plot the activity. It doesn't look as pretty as the audio-derived bandscopes. The question is whether it does as useful a job. The download URL, for those who missed it the first time, is http://www.tech-pro.net/g4ilo/files/k2bandscope.zip . It's still just a zip file you have to install yourself, and you won't find any mention of the program in the web pages. 73, -- Julian, G4ILO (RSGB, ARRL) G4ILO's Shack: http://www.tech-pro.net/g4ilo ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Interpreting Color Codes
After having built a K2, KX1 and numerous other homebrew gear, I have noted by my own observations and comments of others some confusion as to exactly what colors are being observed on small parts, usually resistors and RF chokes. Having been in the printing business for some years, I can say that color perception is often skewed by the light used for viewing. Incandescent lighting seems to be the least accurate for determining the correct colors, particularly yellows, oranges, and browns. Many times I have used sunlight (if available) or sought out a fluorescent lamp (cool white with at least 5200K temperature) to properly interpret colors. When in doubt, I use a meter to confirm the value. Geoff, K6TFZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Interpreting Color Codes
A while ago, I purchased a flashlight from AES which uses four bright white LED's to produce light. The color temperature of the light seems to be very close to daylight, and the light, while extremely bright, is also diffused, so it will brightly and evenly illuminate something nearby (within a foot or two), but it's it's output drops rapidly beyond that distance. It's small, and works great for trying to see around inside equipment (the K2 for example), and I find it very helpful when reading color bands on resistors and rf chokes, since the colors render properly. The flashight is sold under the name 'Lightwave', and it can be found on page 148 of the Amateur Electronic Supply Fall/Winter 2004 catalog. It may be available elsewhere, but I didn't look since the QTH is only about 2 miles from AES store East of Cleveland. (a 'dangerously tempting' place to live if one is a ham!) Their price is $29.99 73, Dale WA8SRA Geoff, K6TFZ, wrote: I have noted by my own observations and comments of others some confusion as to exactly what colors are being observed on small parts, usually resistors and RF chokes...Incandescent lighting seems to be the least accurate for determining the correct colors, particularly yellows, oranges, and browns.

It is worth mentioning that the female retina is generally more richly endowed with rods and cones than the male retina. In fact, a small percentage of women actually experience four primary colors. In other words, for the male constructor it is always good practice to get the female in your life to check the colors. 73, Steve AA4AK At 08:22 AM 1/26/2005 -0800, you wrote: [EMAIL PROTECTED] wrote: After having built a K2, KX1 and numerous other homebrew gear, I have noted by my own observations and comments of others some confusion as to exactly what colors are being observed on small parts, usually resistors and RF chokes.

Re: [Elecraft] Interpreting Color Codes
Folks, Part of the blame for color confusion lies with the part manufacturer. I have many older resistors in my junkbox and the color bands are bright and clear - these older color bands are saturated colors and easy to read at a glance under most any lighting condition, so I know it is not my eyes getting dim!!!. Unfortunately though, I don't forsee the situation getting any better since the component manufacturers primary market is to production lines using automatic insertion devices, and for that market, any reasonable marking will do the job, even if it is not 'people readable'. Bearing witness to this fact is the unmarked SMD capacitors. We folks who have to read the values manually have to take 'second seat' (or maybe even the rear seat). The best tool I have found for myself is a small lighted handheld magnifier with fresh batteries - you can buy these for less than $5 at places like Wal-Mart, Target, local drugstore, etc. I use it for viewing the 'fine print' on capacitors as well, and the only color I have trouble with is violet and occasionally red/orange because many of the red pigments are not well saturated, they are more 'bright orange' than an actual red - yes my wife concurs and she has a keen color eye. 73, Don W3FPR - Original Message - After having built a K2, KX1 and numerous other homebrew gear, I have noted by my own observations and comments of others some confusion as to exactly what colors are being observed on small parts, usually resistors and RF chokes.

Re: [Elecraft] Bandscope
Julian, You have to use a separate serial port for MixW PTT/CW and HRD CAT. HRD uses the serial port connected to the K2, and MixW has no CAT. MixW uses the secondary PTT/RTTY port for PTT/CW and the DTR/RTS from this port are connected to the PTT/CW keying interface. CAT is disabled, and MixW has no CAT connection to the K2. On N4PY, you setup the N4PY program to use the K2 with the Pegasus interface. You tell MixW under configuration/CAT to use the Ten-Tec Pegasus. A window opens and you enter the path to the N4PY program. Frequency/mode commands are sent to the N4PY program which send them to the K2. The N4PY program sends the same from the K2 back to MixW, so MixW will track mode/frequency. You still have to use the secondary PTT/RTTY port for PTT/CW. The K2 can use CAT for PTT, but the N4PY program doesn't do CAT PTT. The best way to do this is to use separate directories for each configuration of MixW. One for MixW using its own CAT, one MixW for HRD and one for MixW with N4PY. You only have the full features of MixW when it does its own CAT. The Align function, for example. I set up MixW to send every function the K2 will take, using macros. When using psk31, I like MixW all by its self. For CW DXing, N2PY is the best, as you can get the K2 to do some things it won't do by its self, like have the filter settings follow VFO A or B selection. I will try your program shortly, and see if I can get it work with MixW using one serial port. 73, Chas At 01:29 PM 1/26/2005, Julian, G4ILO wrote: How do they not fight over the serial port? I loaded HRD, then loaded MixW, and it crashed with an illegal instruction. I closed HRD and then loaded MixW on its own, and it worked fine. My bandscope was slightly better behaved: it reported Error opening COM port when HRD was running. I guess N4PY is providing a virtual COM port for the other apps to use. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KX1 #978, comments and questions on second stage
Andrea wrote: This is my first kit and first big project, so my comments should be taken with a grain of salt. However, I try to follow the instructions very very closely (I've actually read them back-to-back once before even getting the package!) and I'm pleased to hear my little contribution will further improve an already awesome manual. --- As a writer I never object to comments about stumbling points in the instructions. The one you tripped over was something I should have brought it to Wayne's attention. Our objective with the Elecraft kits is that they be buildable by anyone who can solder, follow instructions and do basic electrical measurements such as resistance and voltage. An instruction for something to be ...about x mA... is never good and the worst place to put it is in a manual that will be used by someone who doesn't have a lot of experience with the circuits used in the radio. So I really appreciate your pointing it out. About the yellow vs. orange color coding, I don't know if Elecraft even stocks a 3.7 uH inductor in that size. If they do, I guess it's possible there was a switch. And, yes, I know that some of the colors being used today are not the best. Don mentioned that earlier in a post here. We used to see big stripes or round dots of bright unmistakable colors, but lately I get the feeling that those choosing color-coding paints for some companies are trying to make a fashion statement, not communicate a parts value! I'd say you have a 99% chance of having the right part already. You might drop a question about whether it could be an error to either [EMAIL PROTECTED] (Gary) or [EMAIL PROTECTED]. The latter e-mail address is strictly for ordering parts, but they might be able to clarify whether it is even possible that you got the wrong part based on what they carry in stock.

Re: [Elecraft] Interpreting Color Codes
Jim: It appears that tetrachromacy in the human female comes in two different flavors, funky red and funky green. You can visualize the rods and cones for a particular color as a bandpass filter, just as we use the concept at RF. (Small difference: instead of frequency, optickers think in terms of wavelength, usually in units of nanometers.) Thus, the normal red rods and cones are a bandpass filter with a peak at about 636 nanometers. In a human female tetrachromat with funky red vision, the fourth set of rods and cones are a bandpass filter with a peak shifted 4-7 nm from the normal red. Similarly, in a female tetrachromat with funky green vision, the fourth set of rods and cones are a bandpass filter with a peak shifted 4-7 nm from the response of the normal green. Two filters differing by such a small shift in frequency response does not look like it would have much effect, but the practical effect can be quite dramatic. For example, the perceptual difference between the tetrochromat and a person with normal vision is that the funky red tetrochromat can consistently distinguish between shades of red-pink-orange that are look exactly the same to people with normal color vision. (The fact that the distinction in the spectra of these different shades is real can be tested with optical spectral analysis instruments such as interferometers.) One peer-reviewed discussion of tetrachromacy is in the following paper: Richer color experience in observers with multiple photopigment opsin genes, Kimberly A. Jameson ;Susan M. Highnote ; Linda M. Wasserman Psychonomic Bulletin Review Volume: 8 Number: 2 Page: 244 -- 261 73, Steve AA4AK At 12:58 PM 1/26/2005 -0500, you wrote: Stephen, What are the four colors they see? Thanks, Jim W4BQP Stephen W. Kercel wrote: It is worth mentioning that the female retina is generally more richly endowed with rods and cones than the male retina. In fact, a small percentage of women actually experience four primary colors. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Shaft Encoder - KX1 #897
I've noticed recently that the VFO shaft encoder doesn't seem to count reliably. I usually run in the 100 Hz resolution, and turning it slowly in the increasing frequency direction will sometimes result in a 100 or 200 Hz decrease. The key seems to be slowly, going faster seems to be ok. I am sure this is recent (last few weeks) and wasn't a problem when I first finished the kit. Is this a common problem? Is it fixable? I finished bought the kit at Pacificon in Oct 04 and finished it a couple of weeks later. I will admit that my KX1 is getting quite a bit of use ... I worry the K2 is feeling like an ignored step-child these days. 73, Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'd recommend a very close inspection of the encoder connections. Two or three months is a common interval for a missed joint to start acting up as some oxide forms on the metal surfaces, depending upon the weather (Literally! Humidity, etc. Sometimes a missed joint won't show up for a year or more but it seems they do more often sooner than later.)

[Elecraft] Announcement: Hamlib K2 support
Hello fellow Elecrafters, Hamlib (http://hamlib.sourceforge.net/) is an open source project which provides software developers with a single interface to all supported radios. This allows the developer to support a large number of radios without having to learn how each radio interface works or write separate code for each radio. Hamlib has provided basic support for the K2 for a couple years. It treats it as a generic Kenwood radio. This provides basic functionality, but many of the KIO2's capabilities cannot be used. I am now the maintainer for the K2 portion of Hamlib. The eventual goal is to support the complete KIO2 command set. I say eventual because I am working on it in my limited spare time. My plan is to add a few features at a time as time permits. This will allow incremental improvements rather than a long wait for full support. Any suggestions, ideas, comments, feedback, offers of help, chocolate, etc, are always welcome. I am particularly interested in which capabilities are most wanted and should be supported first. -- 73, Brian VE7NGR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] #4687 is now a K2/100
Well, it has been 2 weeks since all these Elecraft boxes hit the door and everything is assembled, tested and ready for the 160 contest this weekend. The K2, K160RX, KDSP2, KNB2,KPA100, KSB2 and KRC2 went together flawlessly. I can't say enough about the organized assembly instructions and quality of the boards, parts and inventory. I didn't do ANY inventory count prior to construction and everything worked out perfectly. I realize I'm living dangerously, but that's the kind of guy I am. In this case, it all worked out perfectly...even the computer interface. NOW I just need to spend some quality time learning how to operate this rig. ;-) Bob K5WA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
