RE: [Elecraft] Re: K2 #5652 speaker
Shame, shame, shame! So you made a mistake, ea? Welcome to the club :-) I *almost* completed my K2 with no mistakes. Near the end of one building session, I had very carefully soldered a resistor into its place, trimmed the leads and as I checked it off in the book realized I had the right resistor in the wrong spot! Perfectly mounted, nicely soldered trimmed. And of course I lost a couple of parts. Fortunately the spare parts bin had replacements for me so I wasn't held up. Oh yea, I had some bad solder joints as well. Reheating a bunch of connections resulted in issues disappearing. I suspect that very few builders get through the kit having made zero errors.

Re: [Elecraft] KDSP2 - artifact
Johnny, Here are the KDSP2 settings I am using. I'm sure they are not optimum but I am happy with the performance I get. There is quite a bit of QRM here on 80m SSB and the KDSP2 suppresses most of it so the voice is readable. nr 94 10 nt 40 07 Sn G 5.0 SF G 7.0 I don't have 80m transmit capability but I like to listen sometimes to the Canadian traffic nets. I use a little indoor vertical from MFJ and they are very strong signals here in northern Washington. I usually have the KDSP2 agressiveness set at nr2 or nr3 and the voice is usually intelligible. Sometimes the QRM is very low and I don't turn on the DSP. I suspect there are no really perfect settings since each signal being received has its own characteristics. 73, Harvey KN6VP K2 s/n 5022,5404 - Original Message - From: Stewart Baker [EMAIL PROTECTED] To: [EMAIL PROTECTED]; Siu Johnny [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Sent: Tuesday, October 31, 2006 4:30 AM Subject: RE: [Elecraft] KDSP2 - artifact Johnny, I suggest that you search the archive for threads on this subject.

Re: [Elecraft] KDSP2 - artifact
Johny, My 0.02. Underneath I review my K2 DSP SSB speech NR experiences and not the CW ones ( CW NR works much better ). I also encountered considerable K2 DSP drawback problems ( I guess everyone does.. ). ( I know about the free lunch, but even then.. ). I have been tweaking the beta and decay for hours but whatever I tweaked, problems still bother the most where you need the NR most, i.e. with weak signals. Actually, I encountered three kinds of K2 DSP drawbacks : 1. bothering bath tub song sound 2. seriously decreased intelligibility 3. audio artifacts ( distorted audio and splatter like crack sounds etc. ) The audio sample of the K2 SSB speech NR on Elecrafts website ( which seduced me to buy the K2 DSP after having asked a question on this to the Elecraft people, which question was not answered properly ) is kinda misleading ( sorry Wayne ) in that way that it obviously offers a pretty strong signal where the NR indeed does not suffer from decreased intelligibility. Not quite fair of the Elecraft people, since, in contrary, the NR is needed most where the sigs are weakest. I would advocate that the Elecraft people would also offer on their website an audio sample of a weak signal, where the potential DSP buyer can get some idea how the intelligibility suffers by the NR as the sigs get weaker. DSP NR of ( other :-) commercial tranceivers suffers from the very same ( part of the NR concept ) but I feel it wouldn't be a shame for a high quality concept like our K2 to show these K2 DSP SSB NR limitations to a potential buyer before he buys. Some would then decide not to buy this DSP NR. BTW, the real audio artifacts ( not the bath tub sounds and not the decreased intelligibility, but the real audio distortion ) are not really kinda problem ( at least for me ) since they could be easily avoided by decreasing the DSP gain setting ( drawback remains that e.g. changing filter settings, changing bands et al requires changing of the gain setting every time as well ). The bath tub sounds, critisized repeatedly on this list, are no real problem for me. My ears/brain quickly adapt to this and though not pleasant indeed this does not decrease intelligibility for me. Funny to let my inmates think I am talking with little green men from Mars. On the other hand, concluding and to be honest, I must frankly state that even with weak signals ( be it not the really weakest ones ) the DSP does improve intelligibility somewhat if ( and only if for me ) the IF filter is ( default ) widest and the audio filter is ( default ) 2 at maximum or even better at 1. Disadvantage is that in contest ( as I noticed in the very very crowded cq www dx contest last weekend ) that selectivity lacks heavily then and neighbour qrm is hardly endurable. That's why ( in spite of some different opinions on list some weeks ago in the IF shift discussions ) I still do appreciate so much my IF shift in my FT-100 radios ( yes, I do know, please no extra conversion in the K2... ). And, end of all, having said my griefs on the K2 SSB DSP, with some tweaking and some good will, the K2 DSP is still more useable for me than I heard on some commercial radio DSP's. Do I regret having bought the DSP ? No, but with some thoughts as exposed above.

Re: [elecraft] ANTENNAE LINE THROUGH WALL INTALLATION
Hi Bill, When we moved into our house 11 years ago I put a feed through in the concrete block wall. I used 2 inch PVC. I drew out the size of the circle I needed and cut out the drywall. Make sure that there are not any 110v lines where you want to put the feed through. Also try to place it so you are going through a hollow spot on the block. Then I drilled a series of small holes on the circumference. Then I just hit it with a hammer and knocked it out. Same for the outside. I got some stucco patch at Home Depot and patched around the PVC on the outside. I finished it by putting a 90 degree fitting on as a weatherhead. Don't fill it with expanding foam...you'll regret it. A small piece of fiberglas insulation will keep out wind and critters. Anyway that is what I didthe cheap way and still is fine. Went throught Frances, Jeanne and Wilma. 73 de Bob K3YT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KDSP2 - artifact
Hello Johnny! I experienced exactly the same in the recent CQww SSb contest. I really want to know how I should adjust the beta and decay time to minimise the artifact. I don't mind having much less aggressiveness in NR during SSB operation. In some extreme situation during the contest, I simply turned off the KDSP2 Could any of you in the list point me to the right direction? I suggest you tune in a typical signal and change Beta from 99 to 00 and back again. This will give you a good idea of what Beta does. Then do the same for Decay, changing between 99 and 00. Please also read the Design Notes article about the KDSP2 http://www.elecraft.com/KDSP2/kdsp2design.pdf . It explains the techniques used and the limitations of the DSP noise reduction system. There is not best setting of the noise reduction system. The defaults are a reasonable compromise based on input from the field test team. Hearing and sound preferences are different each individual. What is acceptable to me may be very annoying to you, and vice versa. As signals get weak, they become more like noise and are harder for the DSP to separate, just like it is harder for you to separate. Noise reduction will have the best chance to work if the signals are moderate and the bandwidth is wide. Weak CW signals will come through the noise reduction system much better than weak voice signals. I believe that within its limitations, the DSP system does a very good job. But it cannot do miracles :-) So, please experiment with the settings, and understand the limitations of the system. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hi Al group, QCWA maintains a library of old Callbook dating back to about 1913 when the Department of Commerce produced a complete list of stations. Pretty small book! All member applications are verified by the two person HQ staff. It helps to have an approximate year to start the search since this is a manual effort. You just need the original call and best guess on the year. Congratulations! There is an award for members available from QCWA for 50 years. You got me by 10 years. 73, Gary K0BC (former QCWA President) At 07:59 AM 10/31/2006 -0800, Robert Tellefsen wrote: I've heard that the QCWA (Quarter Century Wireless Ass'n) has, or at least had, a complete set of the old Call Books.

[Elecraft] K2 #05810
K2 s/n 05810 is up and running! Got the kit last Friday and it's now Tuesday! :-) No missing or wrong part. Instructions very easy to follow! All three smoke tests went without any kind of problems at all. Output pwr not 15, but 12 watts on 20 meter, but that should be OK, I think... Building the the K1 a few years back was much much more difficult. Parts were missing, parts were broken (or I broke them) and all kinds of difficulties. Took me three months to get that kit together and working properly. However, now only remains the hardest part; aligning the filters on my new K2 and, of course, to compare it to my old trusty IC-703 to confirm that I have not totally wasted my money Håkan / SM6EQO ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] OT: 50 years
Morning Ron and Group - I too was an early 1950s young teen ager with a new WN7VZX call not not long after the novice license was created. In those days the FCC was still going through the available W7 three letter combinations in order the first time since starting in the late 1920s. A few years later they went back and reissued the old calls that had been dropped and my dad received WN7AVK. Which I asked for and received after his passing. :-) Received a couple years ago a very nice wall hanging from the ARRL saying I have been a LIFE MEMBER for 50 years. In those days life member ship was calculated as 20 times a single year dues. Remember it cost me $120. A very big sum when receivers like the SX-71 were selling for $250. 73 Bob W7AVK K2 s/n 1414 Ron D'Eau Claire wrote: Yes, congratulations Vic!

Re: [Elecraft] KDSP2 - artifact
I suggest you tune in a typical signal and change Beta from 99 to 00 and back again. This will give you a good idea of what Beta does. Then do the same for Decay, changing between 99 and 00. Note that if Beta or Decay is at 99, one more increase will wrap it around to 00. Likewise, a reading of 00 can be changed to 99 by a one step decrease. This makes it easy to hear the effect of the change without pressing buttons a great many times! 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [elecraft] ANTENNAE LINE THROUGH WALL INTALLATION
It may sound like overkill to drill at a downward angle toward the outside in most installations, but it's an excellent idea in addition to a good drip loop, especially for frame houses that have walls made of wood and other organic materials. Even a small amount of moisture from snow building up right on the fitting where it exits the wall or the small amount of rain that will contact it directly can seep inside and start dry rot and other problems. Here in the northwest mold is a real concern. It's not just a nuisance, but a life-threatening concern that has killed people, especially children, who are unlucky enough to breath the air containing the spores. A couple of years ago a builder left some tiny gaps in wood siding on a new home that allowed moisture to seep in. Deadly black mold to started growing. Once started it spread drawing moisture from the air. By the time it was discovered because the family was suffering health problems, a new, 1.5 million dollar home had to be totally demolished and much of it disposed of as toxic waste, complete with the crews working in bunny suits inside a tent loading the remains of the house into sealed bags. When you're running open wire feeders or a single end-fed wire, good electrical insulation is important too unless the power is very low. Heyes, in his book Practical Wire Antennas tells a story about visiting a fellow Ham in England who used an end-fed wire that came into the shack through a small hole drilled in the wood frame of a window. On one band a voltage loop occurred at that point. Whenever the guy transmitted, smoke would curl up out of the hole where the wire touched the wood. Heyes observed that he was not aware that the Fire Brigade ever had to visit, but it didn't seem like a good way to get the RF outside G.

Re: [Elecraft] Attic Antenna
Hi antenna challenged fellow hams. You can do your own stealth gutter antenna these days. Two easy ways: 1) Get a combination of metal gutter and one short section of plastic gutter to join two metal halves of a dipole. Remember, you can use shorter than quarter wave lengths of elements, since their cross section is large compared to wavelength. 2) Even easier: Get all plastic. Lay dipole elements in bottom of plastic gutter. Even hook up wire can be used for elements. Glue them to corner of gutter bottom that will be furtherest from the house. Better still, glue them UNDER the gutter corner, so water in gutter will not stand on antenna wire. Use 1/4 inch coax feed to feedpoint, or twin lead, again glued to underside of gutter. Run it into soffit, and then to rig. An all band tuner, will facilitate operations on multiple bands, especially if the dipole is at least 60 per cent of a half wave for the lowest frequency of interest. Your nearest Lowe's or Home Depot is already a stealth antenna store, and you did not know it. Even coax can be purchased there! I regularly use insulators and standoff's from Home Depot's electric fence department for various home antenna projects. They have a compression spring for electric fence gates that is ideal for relieving stress in a dipole element tied to a tree. Unlike a door spring which is extension type, this spring will not elongate with use. At least, not as much as extension springs.

[Elecraft] SSB output overshoot
G'day, When I run the K2/100 into my Acom 1000 I usually set the requested power to about 30 - 35W. I seldom drive the amp more than 400 - 500W output. On CW all is fine but on SSB I notice there is a severe overshoot on the output for the first syllable after changing to TX and after a few seconds pause in talking. With the K2/100 barefoot at 30W requested, on CW the RF bar is steady on 3 but on SSB it overshoots to 4-5 before settling at 3. At present the K2 is set up as twins with the KPA100 co-located with the KAT100. Anyone else noticed this? It would be interesting to put a scope on the output to monitor what happens to the RF level, unfortunately I don't have one. On 40M SSB problem is particularly severe, CW no problem.

Re: [Elecraft] SSB output overshoot
Same thing here, with or without an external amp. CW is as expected. But when switching to SSB I will get full output (sometimes well over 100 watts) at any power setting over 11 watts and sometimes cause a shutdown of my power supply and a reboot of the K2/100. This behavior goes away when I press RF/ALC to switch the bar display to ALC. I have been told there is a mod that may cure the problem but I have not done anything. I just make a point of switching to ALC display whenever I operate SSB. Don K7FJ G'day, When I run the K2/100 into my Acom 1000 I usually set the requested power to about 30 - 35W.
