Q signals, including QRP, pose no such conflict. However, as W3BE points out, other popular self-assigned indicators are illegal, particularly /M, commonly used by mobile stations, a prefix assigned to the UK, That's an odd one! The prefix M is indeed assigned to the UK and used in the amateur service. But in the UK /M it is also the legally assigned suffix to be used when operating from a vehicle or as a pedestrian (leaving aside the recent regulation change in the UK which seems to have made the use of the suffixes for mobile/portable etc. optional). As far as I can read in our regs there's nothing to prevent adding /QRP to one's callsign.

I do find it useful as a QRP operator to know in advance that the weak station I can hear is actually QRP because then (through the theory of reciprosity) I can assume that he'll hear me just as well as I can hear him. Without this clue (/QRP) I tend assume other signals are from normal 100w stations and therefore I'll be receiving 13dB more signal from them than they will from me. I'll switch in my attenuator and see how it still sounds. If he's still workable I'll give him a call (not signing /QRP). I never sign /QRP but accasionally I'll add QRP into a CQ call if I'm on one of the QRP calling frequencies and want to inform other QRPers that I'll be able to hear them, if they can hear me.

Hi Brian, What you are trying to do for your GB Montessori School is exactly what I was going to do for a youg association here near Geneva. But I failes because I did not get any allocation for this project, as it was termed unnecessary!!! Well You did right with the K2, because when you finish the kit, by the book, you know and understand the transceiver as much as their conceptors. As you intend, take the SSB module, beside fone you will be able to run digital mode too. I waited two years before ordering the KPA100 and it is not yet in service! About a year after the K2 and SSB, I instaled the KAT2 antenna tuner. So you can do lot of things whith QRP level and I will not change anything but for another K!!!

Hi Steve, You wrote: I have been using a FlexRadio SDR-1000 rig mostly because of the great DSP. One of the advantages is the external Firewire sound card which is able to boost audio into the headphones. I even found a cheap set of KOSS UR29 headphones have more output than my Heil's. The headphone output on the PRO II causes the headphone audio to distort before its loud enough for me. My 0.02c worth: At ZM1A we use several transceivers - IC-746PRO, IC-780, Kenwood TS-850 and two Elecraft K2s in serious Multi-Single/Multi-Two Cw contesting. With three or four regular operators, (one of whom has moderate hearing loss) each with their own transceiver preferences, we 'discovered' that not all headphones are created equal. We have two Heil, one Sony and two 'el cheapo' (NZ$29.95) headphones. At both operating positions we have dual headphone sockets available. When the Heils are used on the K2s they are either severely mismatched or lack sensitivity. The other 'phones are very loud indeed on the K2s - the Heils are fine on the other rigs. During contests we have reserved the Heils for use by shack visitors. Also, because they rest on the external ear, they admit too much external noise - the cheap 'phones enclose the ears, reducing the inter-operator banter (shouted insults and cheers etc.) to a quiet roar, barely audible above the ambient blower/fan noise. However, the op with moderate hearing loss uses an Audio Enhancer (in QST a couple of years ago) with the Sony 'phones which works very well for him in that he doesn't hear the shouted insults, cheers or blower/fan noise at all. I have tried his Audio Enhancer unit and can thoroughly recommend it - there is a PC board available in the US. 73, Ken ZL1AIH K2s 767, 3725 Fists #9094 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Headphone output levels on the K2?
I have an old set of full size sony headphones that give way more than enough audio output for my moderate hearing loss. Most headphones are rated for the level of audio out for power in, and the ones that cover the ears seem to be more comfortable for me and reduce any outside noise. How you set up the agc effects the audio output level of the k2, and there are resistors that can be changed or eliminated in the headphone circuit, or you could plug the headphones in the ext speaker output. You can also change the tone of the CW to get in a range that you might hear better, I seem to like a much higher CW note than many operators as I am up against the BFO range limit on my K2.

Hello again! I have a requirement that my rigs have relatively high audio output wo/ distortion from the headphone jack. I have a moderate hearing loss, about 45 db down especially in the speech region. The audiologists calls that MODERATE. 60 db down is considered more serious. Wow! Even the FCC wants tx spurs down 40 db or so. I have been using a FlexRadio SDR-1000 rig mostly because of the great DSP. One of the advantages is the external Firewire sound card which is able to boost audio into the headphones. I even found a cheap set of KOSS UR29 headphones have more output than my Heil's. The headphone output on the PRO II causes the headphone audio to distort before its loud enough for me. But the simplicity of CW seems wasted on a lot of hardware hanging off a PC. I am a new CW op. Started last fall getting my code speed up after 31 years as a ham and 29 years on HF. Do about 15 wpm on a good day. A friend of mine thinks the K2 is a good rig for copying weak CW popping through the QRN. The SDR is the best I've found so far. It certainly puts my PRO II to shame on rx. I think the best thing about a kit like the K2 is that adding a small audio stage internally before the headphone jack doesn't ruin the rig. But I would hope that won't be necessary. Also I don't wear my hearing aids with headphones because of feeback. I went with behind the ear hearing aids. Maybe a heaphones with larger deeper cups would help. I welcome comments from those who are familiar with the headphone output level on the K2.

RE: [Elecraft] Getting ready to order K2
Well, you need to get the antenna, coax, a key, microphone? I would nix the KPA100, and the DSP, and even the SSB option as you can receive ssb fine on the base K2. It might be more fun to put up a G5RV and use the low power auto tuner, you can go anyplace on any band that way. If you really want to TRANSMIT the digital modes, I guess you would need the KPA100, but without a tuner, the swr needs to be almost zero, something most multi band antenna's will not do over a useful frequency range on the lower bands. You can receive the digital modes fine with the base K2 I guess. You could build the K2 this year and next year build options, or are you going to build a K2 every year? It seems to me like building a K1 or K2 would teach students a lot more useful info than most of the other stuff in school. Brett N2DTS So after all this discussion of the K3, here I am getting ready to purchase a K2. As I think I have mentioned before, I am setting up a science and technology center in our school, Granite Bay Montessori School. (http://www.gbmontessori.com) We have received a grant from the ARRL to help populate the center with equipment including an amateur station. We have been asked for a list of what we would like and I have decided to go against the flow and request a K2 kit. (They were recommending we choose either a Yaesu FT-897, an Icom IC-706mkIIg, or a Kenwood TS-570SG.) My plan is to have the all the kids work on the kit so that they have the feeling of both participation and accomplishment. I also plan to use the assembly and testing procedures to help cement what they are learning about electricity. The radios mentioned above all fall into the sub $1000 range so that is a calibration point for what I think we can get away with spending. So my question here is, if you were going to outfit a K2 and try to keep the price reasonable what would you get and what might you leave behind. As I see it, the absolute must-have items are: 1. the K2 itself (duh); 2. the SSB module. After that it becomes a bit fuzzy. For instance, I would like opinions as to the need for the KPA-100. Note that if I don't opt for the KPA-100 I *will* get the KIO-2.

What about the DSP module? The kids are learning the code and I hope/expect that there will be a fair amount of CW operation. (The kids actually think that learning the code will be a cool thing in and of itself. I am using the Code Quick system with them.) I also expect some SSB and digital (AFSK, PSK31, MFSK, SSTV, etc.) operation. Anyway, I solicit the input from the folks on this list.

[Elecraft] K3 Noise Blanker ahead or behind roofing filter?
I have K2 SN 1031 and an IC-746PRO. Last week my next door neighbor brought home a large screen TV that looks to be the rear projection type. I didn't pay much attention to it as they unloaded it but now find it puts out lots of QRN. It puts out S9 on the PRO 60 HZ QRN on 20, 15, 10 6 and 2 meters. Those are the bands I have antennas that work. The noise blanker in theK2 and the PRO both eliminate this bad QRN right down to the background noise :-) when there are now strong signals on the band but when a strong station such as the W1AW code sessions come on 20 meters, (20 over 9 in ND), than the K2 using NB1 has problems 5 KHZ or so either side of W1AW. NB2 has problems up to 10 KHZ either side of W1AW and the PRO has problems 15 KHZ either side of W1AW :-( . Is the noise blanker on the K3 ahead of the roofing filter or behind the roofing filter. If it is behind the roofing filter buying a K3 might put me back on the air :-) but if it is ahead of the roofing filter than would I have the same problem as the K2 :-( ? I have looked at the FAQ part of the Elecraft K3 site and do not find the answer to this question.

Re: [Elecraft] Getting ready to order K2
You'll need the SSB module for the digital modes. Keep it on the list. The KAT-2 (auto tuner) also adds a real bridge and a second antenna connector. If you have an antenna that is matched on all freqs you plan on running, and only plan on having one antenna, the KAT-2 won't do anything for you. However, if you'd ever like to be able to easily switch between two antennas, or you'd like to experiment with other antennas, the KAT-2 is a great thing to have. I'd 'leave behind' the noise blanker and the DSP. The noise blanker gets mixed reviews on this list, and the two I have have never blanked any noise at my QTH. (Maybe I just have the wrong kind of noise?). Mark AD5SS On 6/12/07, Brian Lloyd [EMAIL PROTECTED] wrote: So after all this discussion of the K3, here I am getting ready to purchase a K2.

[Elecraft] Signing /QRP
As for legality, for FCC licensed stations, signing /QRP is perfectly legal. FCC Regs 97.119(c) allows for self-assigned indicators. There is an interesting gotcha to the rule. The last sentence of the regulation says No self-assigned may conflict with any other indicator specified by the FCC rules, or with any prefix assigned to another country. Q signals, including QRP, pose no such conflict. However, as W3BE points out, other popular self-assigned indicators are illegal, particularly /M, commonly used by mobile stations, a prefix assigned to the UK, and /R commonly used by repeaters, a prefix assigned to Russia, and used for special ham callsigns for Russian WW2 veterans. 73, Steve Kercel AA4AK -- Interesting what you find when reading the rules! However, I wonder if your illustration of signing /M for mobile really is a problem. It's my understanding that when operating from a foreign country you would place that country's prefix in front of your call, not at the end as a suffix. In other words, in the U.K. I would sign M/W7AQK (or G/W7AQK?) rather than W7AQK/M. So, using the /M as a mobile designator wouldn't really be in conflict with the rules would it? It's being used as a suffix, and not as a prefix. Maybe that's not a correct interpretation, but I've never heard of anyone being dinged by the FCC for signing /M when operating mobile. Of course, I don't think FCC listens much any more to what goes on in the ham bands anyway!

Martin, I would strongly suggest using the 8R signal instead - when inverted it is the same as the signal from the KPA100 ext amp keying interface or the Amp Keying interface for the base K2 that is offered by Tom N0SS. 8R can be set to a delay in the K2 menu and is present about 15ms prior to the onset of RF, 8T cannot be manipulated by the menu parameters. The amp keying interface grounds when active, but you could drive a small (fast) relay that will in turn provide your required voltage. 73, Don W3FPR Martin RATH wrote: Hi !

Re: [Elecraft] K3 Noise Blanker ahead or behind roofing filter?
Hello Brett, Sorry, this is a little off topic, but ... Shunting loudspeaker terminals on an amplifier (or at the loudspeakers themselves) may cause instabilities with some amplifiers due to phase shift, causing them to break into oscillation well out of hearing range, resulting in possible failure of the output transistors (at the very least), and some embarrassment and expense to the applicator :-) It's usually more effective (and will not cause any instabilities to the amplifier) to place ferrite beads over the individual wires or over the pair of wires (whichever works best) as near to the loudspeaker terminals on the amplifier/receiver as possible. Sometimes, due to the size of the connector terminals at the ends of the wires, it is not possible or practical to fit a ferrite bead over the wire. In those instances, you can obtain some split cores from Radio Shack, Mouser, Digi-Key, etc. that will allow you to wrap several turns of wire around half of the ferrite core that is temporarily opened, after which you can close it again. Keep adding more of these devices until you no longer have a problem. 73, Dale WA8SRA Brett gazdzinski wrote: Some caps across the speaker outputs cured it totally!

[Elecraft] Headphone output levels on the K2?
Some headfones have MUCH more gain with the K2 than others. the Kenwood HS-5 is a low impedance phone. I put it on the speaker jack. with that, I have to turn the AF gain down to almost 8 o'clock and the RF gain down to about 10 o'clock to keep from blowing my head off with volume. the HS-5 is monoaural as it comes form the manufacturer. it came with a 1/4 inch jack. Change it to an 1/8 inch monoaural, and it will plug right in to the speaker jack on the back of the K2. I reqired mine to stereo which can easily be done by popping the back off the the headfones. The cable is already three wire, and simply requires moving one lead in the can to make it stereo. If used with just a K2, however, this modification is not necessary. 72, Fred - kt5x ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Now I have to construct the facilities. Well You did right with the K2, because when you finish the kit, by the book, you know and understand the transceiver as much as their conceptors. That is what I am thinking. As technology gets more and more complex, the prevailing sense is that ordinary people cannot understand it. We are creating a society of appliance operators. I am trying to counter that by bringing technical subjects back within the grasp of kids so that they understand that they CAN understand what is going on inside a computer, a cell phone, a television, a rocket, a radio, a robot, etc. Arthur C. Clarke once stated in his third law, any sufficiently advanced technology is indistinguishable from magic. I think he was trying to point out that we can take things that appear magical and turn them into technology that we can understand. OTOH I can see that going back the other way. As the technology gets more complex people give up trying to understand it and it turns into magic. I want to try to stop that trend, at least for a small subset of children. The Montessori method has children learning by manipulating. All their math is done by manipulation of things. The first-year children in a Montessori school tend to have as good a grasp of geometry as most high-school (years 9-12) children do. I am just taking that one step further and applying that to their science class as well. Electricity is more difficult as one is dealing with an intangible so making it hands-on is more of a challenge. I will actually have several cathode-ray oscilloscopes for them to use. (Right now I have an HP-180A I am repairing and a Tek 465 that is working pretty well.) I taught myself to use a 'scope when I was in elementary school. I built my first 'scope from a kit (an Eico 435) when I was 11. A 'scope is the most useful tool I have ever found for working on electronic equipment. I suspect that my fascination with the 'scope played a large part in my visual understanding of electronics. I have one lab where they use a function generator and a 'scope to help the kids learn about the relationship between amplitude, time, frequency, and wavelength. It lets them view what they are learning and tie it to the geometry that has been the cornerstone of their math. (BTW, in a Montessori school kindergarten students understand the concepts of multiplication, division, squares, and square roots. By the time they hit their 4th year they are surprisingly advanced in their grasp of mathematical concepts including the beginnings of algebra so I can begin to teach them the physics from a quantitative as well as a qualitative point of view. This year they were learning about ratio and proportion as applied to simple machines. The older kids designed and built their own throwing machines, e.g. mangonels, balistas, and trebuchets.) As you intend, take the SSB module, beside fone you will be able to run digital mode too. That is the idea. I am not sure I will get to the point where I can explain modulation from a mathematical point of view but I can give them the practical idea. I am looking around for a good, old spectrum analyzer so I can show them things in the frequency as well as the time domain. I waited two years before ordering the KPA100 and it is not yet in service! Thank you. I have had a couple of private messages say that too. About a year after the K2 and SSB, I instaled the KAT2 antenna tuner. I am hearing similar things from people.

Re: [Elecraft] K3 Noise Blanker ahead or behind roofing filter?
Most RF-spectrum noise generated by TV sets and computers and radiated by the power line is common-mode noise, and the typical differential-mode (in-line) power filter will do nothing to suppress it. You need to make a common-mode RF choke. Get some large ferrite toroid cores (Palomar Engineers as well as others sell them) and wind the entire power cord of the TV through a couple of these in series. (In less severe cases, just one toroid may do the trick.) The toroid needs to go as close to the TV set as possible, as any unshielded conductor between the toroid and the power supply will still radiate. You can also encase the whole power cord in clamshell ferrites if you can find them in the correct size, but I've found this to be less effective than toroids. The benefit of this method is that you don't have to supply an extension cord to replace the length of the power cord you wound through the toroids. Bill / W5WVO Brett gazdzinski wrote: I would ask the people if I could put a filter on the power line to the TV. That might reduce or eliminate the QRN.

[Elecraft] Re: K3 Noise Blanker ahead or behind roofing filter?
Hi Ken, The short answer is both. The 1st I.F. noise blanker module is ahead of the roofing filters, so it can blank wideband pulse noise. It has a wide AGC range and various threshold and blanking width settings. There's also a DSP noise blanker *after* the roofing filters. This blanker has the advantage of not being modulated by signals outside the roofing filter bandwidth. Of course you can't use it in all cases, because the roofing filter stretches the pulses and thus requires longer blanking times. But I have some noise on 160 m that the DSP blanker suppresses by some 40 dB, making otherwise completely inaudible signals stand out clearly. We're also experimenting with reconstructive blanking algorithms to make the DSP blanker even more effective. The noise blanker LEVEL switch displays the parameters for both the hardware blanker and the DSP blanker on the VFO A and VFO B displays. You can then adjust either or both to see which is most effective on noise. The settings are stored on a per-band basis. 73, Wayne N6KR On Jun 12, 2007, at 4:50 AM, Kenneth A.

RE: [Elecraft] Getting ready to order K2
First of all, there was substantial interest in the K2 sitting alongside the K3 at SeaPac in Oregon June 2 and 3. It's a great rig and, as several people pointed out, one is assembled at lower cost from individual parts. Elecraft just did a major update of the K2 Owner's Manual to be sure everything was current and complete for those who will continue to buy K2's for a long time to come. I'd consider the analog or DSP audio filters entirely optional. I find the basic I.F. filters in the K2 more than adequate for virtually any situation. Sure, the denoiser is handy under tough signal conditions and the extra selectivity is handy from time to time, especially if one needs the signal to stand out alone from the QRM to copy it, but it's a significant cost for something that isn't needed most of the time. Was it the ARRL who recommended the Yaesu, Icom or Kenwood rigs? How dare they leave Elecraft off of that list? If so, it's time to sharpen my rhetoric (don't use a pencil much any more) and shoot off a letter (er... Email) to Newington! Ron AC7AC -Original Message- As I think I have mentioned before, I am setting up a science and technology center in our school, Granite Bay Montessori School. (http://www.gbmontessori.com) We have received a grant from the ARRL to help populate the center with equipment including an amateur station. We have been asked for a list of what we would like and I have decided to go against the flow and request a K2 kit. (They were recommending we choose either a Yaesu FT-897, an Icom IC-706mkIIg, or a Kenwood TS-570SG.) My plan is to have the all the kids work on the kit so that they have the feeling of both participation and accomplishment. I also plan to use the assembly and testing procedures to help cement what they are learning about electricity. The radios mentioned above all fall into the sub $1000 range so that is a calibration point for what I think we can get away with spending. So my question here is, if you were going to outfit a K2 and try to keep the price reasonable what would you get and what might you leave behind. As I see it, the absolute must-have items are: 1. the K2 itself (duh); 2. the SSB module. After that it becomes a bit fuzzy. For instance, I would like opinions as to the need for the KPA-100. Note that if I don't opt for the KPA-100 I *will* get the KIO-2. Since I expect to be using this rig mostly in in the classroom with a matched antenna (I am leaning toward the GAP Titan DX as I have one and like it), I probably would not opt for the KAT-2. What about the DSP module? The kids are learning the code and I hope/expect that there will be a fair amount of CW operation. (The kids actually think that learning the code will be a cool thing in and of itself. I am using the Code Quick system with them.) I also expect some SSB and digital (AFSK, PSK31, MFSK, SSTV, etc.) operation. Anyway, I solicit the input from the folks on this list.

All that means is that it's more important to tune in signals using narrow filters (like any other mode) rather than dump the whole audio bandwidth into the computer and do the filtering there looking at a 'waterfall' display. Trying to let the computer filter signals means the receiver AGC is responding to the strongest signal in the passband and suppressing all the others in proportion.

RE: [Elecraft] Getting ready to order K2
This was a good usable rig for very little money, not sure if they are still selling the entire kits or just the boards, or what, but for $80.00, it was a well working radio, and easy to build. http://emtech.steadynet.com/nw.shtml All the verticals I ever used had VERY narrow bandwidths on the lower bands, my butternut has about 40kc on 80 and if I add the 160 coil, that's about 10 khz before the swr is high! Maybe the gap stuff works different? Its great the kids show ANY interest is anything other than TV or video games. In my day, I built a 6SN7 regen out of the encyclopedia we had (world book). Next was a 6146 xtal transmitter. What fun! I cant say I think I learned anything in school after about 5th gradeeven science class was dull! Sounds like you are doing great work.

I had forgotten a microphone but will probably get a good cardioid dynamic mic. I would nix the KPA100, and the DSP, and even the SSB option as you can receive ssb fine on the base K2. I understand but I want the kids to have the opportunity to operate voice and digital modes too. It might be more fun to put up a G5RV and use the low power auto tuner, you can go anyplace on any band that way. I may be limited in horizontal space to do that. If you really want to TRANSMIT the digital modes, Yes. I guess you would need the KPA100, but without a tuner, the swr needs to be almost zero, something most multi band antenna's will not do over a useful frequency range on the lower bands. I have a GAP Titan DX that was given to me. I was skeptical at first but now am a believer. It has amazing bandwidth with lower SWR. You can receive the digital modes fine with the base K2 I guess. You could build the K2 this year and next year build options, or are you going to build a K2 every year? Well, the K2 will be the school rig. Some of the kids have expressed an interest in building their own stations. This is why I am introducing CW early as QRP CW is certainly the least expensive way for a kid to have his/her own station. I will probably pick out an inexpensive QRP transceiver kit for them to build. Since the school usually pays for projects like this the K1 might be a bit out of reach. (Hey Wayne! Do you have a good educational discount? :-) I am leaning toward something like the Small Wonder SW+ transceiver kits and let the kids build their own enclosures in wood shop. It seems to me like building a K1 or K2 would teach students a lot more useful info than most of the other stuff in school. Ah, you understand where I am going with this then.

[Elecraft] Getting ready to order K2
I wonder how a whole class of students, some with potentially no electronics or mechanical skills - could do, building a K2 HF Transceiver? Who would ride herd over them, steer them, and check their work as they soldered and placed 100's and 100's of electronic and mechanical parts in place, in the correct order, position, and polarity? You might have better success, and a considerably better communications radio, by going with the K3 - even the 10watt model, with SSB and etc. For under $1400 - you'd have a much better radio. And one wouldn't have to be concerned with 35 students and their associated soldering skills. :) :( Rather than solder all class long - they could study, and be presented the theory and idea behind each of the K3 pre-built modules. Just a thot . Long long time back, I took a 10-week Electronics course in Ft. Erie, Canada - and there we each built a simple superhetrodyne AM radio. Very simple, and it even had tubes. But we learned the electronics theory about each item, as we built that radio. That simple course sparked something in me, and I went to attend the Univ. of Buffalo's SUNY EE School - and did right well there, graduated in 73. Good luck on your fine educational class!

Hallo Julian, Fortunately the CE requirement does not apply, as it is a personal import. AFAIK the CE marking is not always necessary for kits, otherwise whether personal import or not, the CE marking is always required, even for stuff like a penlight! The CE marking is not required for customs, but without it, it is highly questionable that you are allowed to operate the equipment, assuming it is not homebrew or a kit.

On page 61 of the manual in the vco alignment, I measured the voltage of r30 first out at 2.33. that was with the tuning slug, L30 turned all the way in. turning the slug out the voltage changed to 2.44. this is no where near the 6 volts. My question is, the manual says if the voltage does not change, refer to troubleshooting. I can't find anything in troubleshooting that refers to this.

I was just wondering how many here use SSB with their 15 watt K2? Does it meet your expectations? The reason I am asking is because, I have the SSB board ready to install. I have been using the basic K2 the last few days in CW mode and I really like it since I work mostly CW.

So, I'm trying to gather as many opinions as possible so that I can sit and torture myself further. :-) I did own an Argonaut V for about eight months. It would put out about 20 watts which made SSB a bit more of a challenge. Since I have the Kenwood that will put out 170 watts, believe it or not, I'm thinking that I would probably not use the SSB option unless it's for QRP SSB. Your opinions are welcome. I should mention that I'm not planning to add the 100 watt amp to the K2. If I'm going to do that, I'll just buy a K3! I also work a lot of QRP CW.

Re: [Elecraft] K2 and SSB
Gary the K2 works nifty on SSB, either as a 15 or 100 watt radio. even with only a vertical I would not hesitate to call someone DX on 20m. of course its easier when sunspots are higher! i have made many contest QSO's running SSB QRP. and this is a great rig for running PSK31. so if you have the board go ahead and install it! count the dB's carefully and convert them to the number of S-units. i am not saying don't QRO, as when i discovered working DX on 80m CW is interesting I added 100w to my K2. i won't debate the K2 vs. K3 trade! converted to $ per dB of performance, i am not sure where this will fall. 73, curt --- Gary D Krause [EMAIL PROTECTED] wrote: I was just wondering how many here use SSB with their 15 watt K2?

The first month you get the certificate and and sticker for that month (say January). Then for each successive month you do it again and get another stick (for that month). Get all twelve (20 QSOs X 20 minutes per month X 12 months) and you get plaque for the anniversary award. To allow late comers to get the plaque, you get a free month sticker for any two consecutive months the feat is achieved. These can be used for missed months. The conversations have been wonderful.

[Elecraft] Signing /QRP
I respectfully disagree with the argument that folks with small signals are QRP or that running more power makes you less likely to ragchew on CW. I know many QRPers who have significant antenna systems and many 100 watters that have piss poor antennas. You can argue that folks who operate around the QRP frequencies are more likely to ragchew, be more polite, or whatever. My feeling is that folks who have built their own equipment and/or antennas, or who have challenges to just get on the air are more likely to chew the fat. Mostly because they are happy to play with hand-ons stuff. Cheers, Julius n2wn ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The reason I am asking is because, I have the SSB board ready to install. I have been using the basic K2 the last few days in CW mode and I really like it since I work mostly CW. I have a Kenwood TS-530SP that works great on SSB so, I'm trying to decide if it's really worth installing the SSB option. So, I'm trying to gather as many opinions as possible so that I can sit and torture myself further. :-) I did own an Argonaut V for about eight months. It would put out about 20 watts which made SSB a bit more of a challenge. Since I have the Kenwood that will put out 170 watts, believe it or not, I'm thinking that I would probably not use the SSB option unless it's for QRP SSB. Your opinions are welcome. I should mention that I'm not planning to add the 100 watt amp to the K2. If I'm going to do that, I'll just buy a K3! I also work a lot of QRP CW.

RE: [Elecraft] K2 and SSB
There's a small but significant advantage to staying with the standard Elecraft OPT1 filter bandpass, rather than using one of the wider bandpasses you can achieve with the optional capacitor kit. The narrower bandwidth helps the S/N radio. The less bandwidth the 5 watts occupies, the louder it'll be at the receiving end.

If you are feeding a resistive 50 ohm dummy load with good coax, the wattmeter (either internal or external) should read 1:1 even with a KPA100 problem.

[Elecraft] Crystal Clear book
I just finished reading a book, CRYSTAL CLEAR, by Richard J. Thompson Jr. The book presents the fascinating history of the World-War-II effort to provide crystal frequency control for military radios. This was critically important, because radios without crystal control drifted badly, which made net operation difficult and also made it impossible to assign closely-spaced radio channels. The book was announced in the New Book section of the June 2006 QST. The book's author had written a nice summary article on the same topic that appeared in the January 2004 QST. I make mention of the book here because I know that many members of the Elecraft list have long memories and share my fascination with radio's technical history. (Like Ron, AC7AC, I too remember Edward R. Murrow's reports from London during the Blitz.)

Re: [Elecraft] Feed PTT thru coax for DB6NT Transceiver
Martin, I would not recommend that you take the 8 volts out of the K2. As an alternative, develop the required DC voltage at the transverter end, and then ground it during transmit with the K2 amp keying circuit. OR - key a relay at the K2 end with the amp keying circuit, then use the relay contacts to apply voltage (from a separate supply) to the transverter. The 8 volts inside the K2 should not be loaded down with external devices. If the current requirement is very low, it may be OK, but in this case, we do not know the current requirement, so a relay is my recommended solution. 73, Don W3FPR Martin RATH wrote: Don and Tom, Thanks to both of you for your answers.

The obvious reason for this was that it was being used to patch between pads that are only about 3 mm apart.

Re: [Elecraft] Strange KPA100 behavior
Mike, Fine, and thanks for clarifying that you do have the latest level KPA100. The fact that you have lower than expected resistances at R26 and R27 suggest that you may have something wrong with U5 (it could be damaged). Initially, you should make the DC voltage measurements on U5 and U6 and Q10 and Q11 (see the DC voltage chart at the end of the manual). The prime suspects for a problem like yours are D16 and D17, T4, U5, U6 Q10 and Q11 - of course the associated resistors can be suspect too, but are usually not a problem if it worked before. (if it has never worked, check the resistors associated with the devices listed above (see the schematic to identify the resistors). Since your KPA100 is producing maximum power, I suggest that you remove the power from the KPA100 and feed only the DC coaxial connector on the base K2 - that will limit the power output to the QRP level (but it will still produce maximum power from the base K2, so keep the keydown periods short. If the DC voltage measurements check out with no problem indication, I can help you trace the detected voltage from R26 through to the VRFDET signal. 73, Don W3FPR Mike Geddes wrote: Don, This evening I have had a chance to look at my KPA100 again.

Of course, one of the pioneers was Hazard Reeves (K2GL, SK in 1986). Buz was a world class engineer and beyond that, is still well known for the winning-est Multi-Multi Contest Station in history (I operated there from 1976 to 1986). In fact, the Multi-Multi Category was invented because of Buz' operations in the CQWW DX Contest. He won everything, so they created a new category to distinguish what he was doing from what others were doing. Can you imagine competing head to head as a Single-Op with M/M because there was only one category?

Wayne: Your mention of some reconstructive algorithms was very interesting to me. For some time, I've wondered if it would be possible to have a circuit which would regenerate a CW signal and play it back in a noise free environment. I'm not an engineer, but I seem to remember that work was done a number of years back with UARTs and the like to regenerate fading or noisy TTY signals and they seemed to work reasonably well. At the very least, such a system might provide considerably improved copy under heavy noise conditions. I don't know of any other radio currently using audio reconstruction. Perhaps it's because it doesn't work or hasn't been high on the priority list. In any case, I think it's a very interesting idea.

Christiansen Cc: elecraft@mailman.qth.net Subject: [Elecraft] Re: K3 Noise Blanker ahead or behind roofing filter? Hi Ken, The short answer is both. The 1st I.F. noise blanker module is ahead of the roofing filters, so it can blank wideband pulse noise. It has a wide AGC range and various threshold and blanking width settings. There's also a DSP noise blanker *after* the roofing filters. This blanker has the advantage of not being modulated by signals outside the roofing filter bandwidth. Of course you can't use it in all cases, because the roofing filter stretches the pulses and thus requires longer blanking times. But I have some noise on 160 m that the DSP blanker suppresses by some 40 dB, making otherwise completely inaudible signals stand out clearly. We're also experimenting with reconstructive blanking algorithms to make the DSP blanker even more effective. The noise blanker LEVEL switch displays the parameters for both the hardware blanker and the DSP blanker on the VFO A and VFO B displays. You can then adjust either or both to see which is most effective on noise. The settings are stored on a per-band basis. 73, Wayne N6KR On Jun 12, 2007, at 4:50 AM, Kenneth A.

Re: [Elecraft] RE: [QRP-L] CW Field Day operations in Northwest Oregon
They obviously feel threatened by a ham with superior skills. :) The animosity exhibited even by some old-timers when the topic of CW comes up is amazing to me, especially in the context of contest. Don't they realize that, in most contests, you get more points for CW contacts than for phone contacts? 73!

Re: [Elecraft] CW Field Day operations in Northwest Oregon
This is another fantasy of mine. Form a club of CW operators who like to operate in the boonies and actually build their own rigs. Glory be I think that may draw a few fine souls. Maybe even a glowbug or two :) Kevin.

If there aren't, why not start your own? That's what I did many years ago, when I got fed up with the local clubs' approach to FD.

Re: [Elecraft] Crystal Clear book
In a battle war situation - the last thing a operator military person needs to have to do, is dial in an exact frequency. I suspect this was one reason for crystal control. Also in secure comms nets - periodic crystal changes, would make code book syncing net frequency very practical and reliable. By definition, in the military, all radio operators - where war fighters first. Does anyone remember Gabriel Heater? When I was a kid, out at my grandparents cottage south of Buffalo - everyone used to sit around the Philco radio - and listen to Gabriel Heater's news program, at that time about WWII. . and all the ship's at sea. 73, de Fred N3CSY ...just got a TH-F6A toy, should keep me busy, till K3 arrives :) TV dinner still cooling?

Re: [Elecraft] Crystal Clear book
Hi Fred, Yes, I remember Gabriel Heater news; but the all the ships at sea was the tag line of gossip commentator Walter Winchell. Remember him? He also had the snappy code burst at the start of his broadcasts. Can you believe, Andy Rooney of CBS 60 minutes was a reporter for Stars and Stripes newspaper in WW2? 73, Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Considering the fact that many if not most Hams today would not consider picking up a soldering iron to do more than attach a connector to a cable, I agree they are probably being cautious. After all, I understand the ARRL has launched their own program of technical courses to help Hams become more technically competent. They are putting me through a one-week intensive training program to help me integrate their recommended lesson plans into my syllabus. They are also training us on the Parallax Boe-Bot robot kits. I am going to get several of those too. The kids get to build those as well and it introduces them to programming. Again, the hands-on aspect of writing a program that then causes the robot to behave a certain way in the physical world should be another reinforcing learning tool. The comparison is striking: when I was in the 6th grade our class built crystal sets as part of science. I already had a three-tube regenerative receiver so I got an A without breaking a sweat G. We didn't even do that in our classes. I am going to show kids how much fun making things can be. Oh, and I have to get T-hunting and emergency communications in there too. I want to make sure there is something for everyone. 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] flagrantly OT: name of WWII comedian who ...could teach Morse code to a dog....?
I heard this very funny piece on NPR a couple of years ago about a 40's-era comedian who did skits about military life. In one skit he played a radio-class instructor disgusted with a new class of underachieving recruits who were there to learn the code. He chastised them for not studying while bragging that he could teach anyone the code, even a dog, which cracked up the studio audience (or, I'm not sure which, prompted the laugh-track operator to open it up all the way). Being not quite 50, I wasn't there. I bet a few of you were :) I couldn't find his name with a web search. Anyone have a clue? tnx Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
