Re: [Elecraft] Elecraft. G5RV Question
Leigh, My doublets work great on the higher bands. In theory, the lobe configuration does changes with wavelength n of the wire, so you have roughly 2n lobes. But you also get some gain, and, more importantly, a lower peak angle of radiation. You can read all about it in W4RNL's great write up: http://www.cebik.com/wire/abd.html 73, steve, kx7r Leigh L Klotz, Jr. wrote: What is the difference between the G5RV and the twinlead-fed 102' doublet with a current balun at the coax-to-balanced transition mentioned as an alternative? Is it just the random length of twinlead rather than a calculated length? Or is it a long run of coax vs. a short one? I know some people with G5RV's advocate a long coax run, but that just adds loss, so I kept mine as short as possible. Mine works ok on the low bands, but poorly on 15m and up. Wouldn't an 80m dipole be even worse, with many more strange lobes? Leigh / WA5ZNU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Elecraft. G5RV Question
The 80 m dipole feed with ladder line and a tuner can work well even with multi lobes on the higher bands. See any edition of the ARRL Antenna book or handbook for typical patterns, or www.cebik.com antenna web site for patterns. If you take into account the lobe directions you will have fine results. Just orient so that lobes are mainly in directions of ham populations on the higher bands. Stuart K5KVH
[Elecraft] K2 and FSK (summary)
Ron and Dick I appreciate your interesting posts. As Ron says AFSK is as clean as FSK if AF in level is set properly. Last week end I enjoyed CQ WW RTTY contest with QRP K2 (5W) One of major problem was that AF in level must be re-adjusted each time when I change Band. This is not in the case of FSK. I believe FSK is much simpler at least in operation. I have same problem (re-adjusting AF in level) when I change mode (RTTY to PSK31 etc) This is why I posted this question on the list. I hope Elecraft plans something new in this area.

[Elecraft] Elecraft. G5RV Question
Hi Guys, my main rig is a K1 feeding a multi dipole for 80/40/20 with no ATU. I am thinking of taking down the dipoles and trying a full size G5RV. Questions: Will the KAT1 ATU tune up on all bands from 80-15m I will be using about 80 feet of 50ohm coax to get from the matching section to the rig, am I going to get big losses in the coax due to the high SWR on most bands? The beauty of the G5RV is that it can be fed with coax but with only 5W I don't want to waste all the power in the feeder. I intend to build the G5RV myself (like all of my antennas), how accurate does the length of the matching section have to be? does it need tuning in some way. Can I use any insulated wire for the open wire section? The multi dipoles have been great performers but it's a lot of wire up there and very heavy, I thought that with the G5RV being one single top wire it will be lighter and I may be able to get it higher. Any thoughts would be appreciated.

[Elecraft] K1 Transmit Offset
Hi all, My base station rig is a K1 that I did not build. Is there an easy way to determine the actual transmit offset? It doesn't seem to be available from the menu. The manual section on offset adjustment says to place switch S2 on the bottom of the rf board in the test position. Is there an easy way to get to this switch? (I have found capacitor C13.) I have thought about checking the transmit frequency externally with an o'scope, but there wouldn't be a way to externally (accurately) measure the recieve frequency for comparison. Obviously I am just beginning to explore the inside of this fine rig.

RE: [Elecraft] Elecraft. G5RV Question
While the G5RV has a lot of advocates for multiband use, it works much better if you bring the parallel feedline all the way to the tuner. When used for multiband, with coax and the matching section, you will likely find a higher than desirable SWR on the coax except on 20 meters. I have found the claims for the G5RV antenna to be highly exaggerated. For good unbiased information on the G5RV (or most any other antenna for that matter) check out the wealth of information gained by modeling at L B Cebik's website www.cebik.com. Your multi-dipole will be more efficient on 80 meters, and can be fed directly with coax and no tuner. If I were in your shoes, I would leave well enough alone unless there is some other overriding reason to change it. 73, Don W3FPR -Original Message- Hi Guys, my main rig is a K1 feeding a multi dipole for 80/40/20 with no ATU.

Re: [Elecraft] Elecraft. G5RV Question
Martin, Before going to a G5RV, I would try feeding your 80 m dipole with 450 ladder line to a (good) 1:1 current balun and use a short run of coax to the K1. I use this setup to feed 102' and 44' wires. My Ks tune them on any of the bands they cover (you need a bit of additional L/C help on 160) and they work great.at QRP levels. 73, steve, kx7r [EMAIL PROTECTED] wrote: Hi Guys, my main rig is a K1 feeding a multi dipole for 80/40/20 with no ATU.

Questions: Will the KAT1 ATU tune up on all bands from 80-15m --snip-- Howdy Martin: Since you are planning on using a tuner anyway why not just put up a center fed doublet cut for the longest frequency you want to operate on, say 80m. Using a balanced tuner like the ZM2 Z-match tuner with this antenna will prove very effective...better than the G5RV I believe. Remember, the original G5RV was designed to provide a couple of DB's of gain on 20m only.it was later re-designed a bit to provide multi-band coverage.certainly not an optimum antenna by any means. I currently use a 170ft center fed (ladder line) doublet (extended Double Zepp on 40m) with a balun and remote tuner and it is the best wire antenna I have ever put up. Right now your multi-dipole antenna is about as good as you can get for multi-band coverage and you don't need a tuner with itso your system is pretty darn good as it is.

Your multi-dipole will be more efficient on 80 meters, and can be fed directly with coax and no tuner. If I were in your shoes, I would leave well enough alone unless there is some other overriding reason to change it. FWIW I had a multi-band trap dipole from Spi-Ro that worked OK but was frustrating because it seemed multiband meant equally bad on all bands. There wasn't a single ham frequency at which it was naturally resonant -- thought it had many non-ham-band resonant frequencies. I replaced it with a 40/20/10 multi-dipole which can be coax-fed and is well under 2:1 throughout the CW portions of 40, 20, and 10 and is reasonably resonant on 15. I can tune it with the KAT100 very easily for any band including 80 and all the WARC bands. I'm not an antenna guy, but I've gotta believe more signal is getting out of this dipole than was with the multiband antenna that required traps, baluns, and a tuner.

[Fwd: Re: [Elecraft] Elecraft. G5RV Question]
Sorry, Don. I didn't mean to spam you, I forgot to make sure the TO: address was going to the reflector! I meant for this to go out to everyone. Sorry Original Message Hi, Guys. The thing you have to remember is that the G5RV originated in the days of final amplifiers built with vacuum tubes and adjustable pi-output networks. The pi-output network itself functions as a narrow-range antenna tuner. I've used G5RV's quite successfully without an external antenna tuner on all bands available on my trusty Kenwood TS-820s. I found the G5RV to work as advertised, with the load presented to the rig falling within the tuning range of the output network. So, the claims of a G5RV not needing an external tuner for multi-band use can be fulfilled with an older rig. However, using a G5RV as a multiband antenna on a modern-day, solid-state rig that always expects to see a 50-ohm, non-inductive load simply won't fly. Like Don said, it was originally designed as a 20-meter antenna, so you can expect reasonable performance there. I agree with Don on the final recommendation. Until you get an ATU, keep the multiple dipoles. Experiment with the G5RV (and other antennas) after you get an ATU.

Re: [Elecraft] Two Band Moxon/wire beam
Charles, With dual band close spaced beams, everything interacts. You can try adjusting the wire lengths by the percentage you were off your target frequency, or just operate them as they fell. They will vary with height, and there is no compelling need to have them exactly resonant in cases like this, as long as your are getting about the beam action you want. Your SWR actual at 21 feet seem to be OK for operations. Or just use a tuner to touch up the match.

Re: [Elecraft] Elecraft. G5RV Question
Certainly, traps and baluns may contribute some losses as well as loading coils may. Tune losses in a decent tuner are pretty low, unless you are trying to match outside its design range. There is no advantage save not having a reactance term to match out, to having resonance on the antenna. You will not get significantly more out of the resonant antenna, if the reactance canceling means is high efficiency. In other words you cannot hear the difference between a resonant antenna and one near resonant. See the writings of various antenna authors such as Cebik, Walt Maxwell, (in Reflections) and others such as Bill Orr.

Re: [Elecraft] K2 and FSK (summary)
hi Aki - absolutely right - for contest situations, it is especially useful to not have to worry about readjusting the radio when changing bands. But even for casual operating, its nice to be able to set the mode and go, without having to make adjustments. This past weekend, I operated the CQWW RTTY contest at another operator's station. Since he was not a RTTY op, nor did he have SO2R capability, I hauled two FT1000Ds and a desktop computer to his QTH. I had wanted to operate high power, but after getting two monster rigs, keyboard, and monitor on his table, there was no way I was going to be able to deal effectively with his two non-auto-tune amps - so I went low power and did all right. But lugging those big radios was definitely non-optimal! Later, I was thinking about the perfect portable set up for the future... how cool would it be to have two K2/100s with peaked and tweaked data filters, plus a KPA800 or KPA1500 amp with its SO2R ability (and auto-tune and it can sit under the desk)? I have always hesitated to use the K2 in RTTY contesting because you cannot zero the RIT by computer command, and because of no FSK (and also because you have to use non-standard tones to get within the filter bandwidth capability - with practice, I have gotten pretty good at tuning to pitch.) The latest RTTY contesting software, with the ability to have multiple receive windows with different settings, has made it so that I hardly ever touch the RIT anymore. If we could get FSK, I would probably get past the tone issue... Looking at the schematics (RF sheet 1, left side), if I understand the circuit correctly, all it would take is injecting a voltage of the correct value and summing it with the thermistor voltage to create a 170Hz shift (shifting the 8B value to the thermistor might even be easier). What I don't know is: 1. How precise this voltage would need to be; 2. Whether the same voltage would work for all bands. Any insight on how baked this scheme is, before I start messing up my K2, will be very much appreciated! thanks - jeff wk6i ps: plan B: inject the two tones directly into the transmit audio. this sounds harder.

Last week end I enjoyed CQ WW RTTY contest with QRP K2 (5W) One of major problem was that AF in level must be re-adjusted each time when I change Band. This is not in the case of FSK. I believe FSK is much simpler at least in operation. I have same problem (re-adjusting AF in level) when I change mode (RTTY to PSK31 etc) This is why I posted this question on the list.

RE: [Elecraft] Let me build your K2
I appreciate Alan's occasional reminder of his available Elecraft building services. Alan recently upgraded my auction acquired K2 #2318 with SSB and IO2 to a revision B K2/100 adding the NB, DSP, PA100, 60M, and 160M modules. The upgrade job was complicated by the fact that the rig had been previously involved in a house fire and rescued by me from the charred debris through repeatedly cleaning the boards with alcohol and distilled water. I also had to replace the front panel, melted knobs, melted bezel, and melted buttons and scrub the soot blackened exterior. For about a year, I could smell a faint smoke odor every time I used the rig. A year and a half after my restoration to operable condition, the K2 stopped responding to computer control. I had seen Alan's e-mails and decided it was time to ask Alan for repair help and for the upgrades that I had been wanting for some time. Alan began to work almost immediately and kept me advised of his progress by e-mail as he repaired defects and built the upgrades. Working on the fire affected boards was difficult because each new solder point required recleaning. He finished the project promptly and charged very reasonable fees for his labor. My commercial surface mount technology rigs did not survive the fire, only the K2 because of its modular easy to work on design. I am greatful for Alan's services that again enable me to use my K2 fire survivor. The K2 worked FB QRO during last weekends CQ DX RTTY contest.

[Elecraft] Elecraft email List Official Guidelines - Updated 9/26/05
ELECRAFT eMail LIST GUIDELINES For those of you who are new to the list, (and for those of us who have rapidly failing memories..), here is a quick list of things to remember when posting to this list. Please save this for future reference. The most important thing to remember is that this is only a hobby - Let's have fun! 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft@mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like [EMAIL PROTECTED] If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with [EMAIL PROTECTED] from your physical address of [EMAIL PROTECTED] will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and monthly afterwards.) 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. Always delete -everything- from the prior post except what is necessary to keep your reply in context. Most copied messages can be reduced to one or two sentences to retain context. Remember to delete the email list footer from the previous post and especially avoid copying a long posting and adding 'Me Too!' or something similar. As the number of users on this list grows (over 1500 now) we need to work to minimize information overload... If a reply is -not- of interest to the list, just reply directly to the posting party. 4. If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. Just click on the ones you are interested into read. You can also set your list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 5. ***Please keep all postings cordial. *** Restrain the urge to email someone admonishing them about a posting. The last thing we want to do is to scare anyone off the list. Overly aggressive postings and negative comments about other posters only serves to scare away new potential list members. Waiting over night before hitting 'send' really helps to put things in perspective.. If you have a complaint about someone or a thread please email it directly to me ( [EMAIL PROTECTED] ) and I'll address it. 5a. Please do not post asking people to stop a particular thread, no matter how long, off topic or repetitive it gets. Email me instead :*). I will step in when I feel it is necessary to end a thread. 5a1. Please exercise restraint in posting when a thread is getting heavily covered. 30 posts on one topic in a day (like the recurring CW thread) is usually excessive. 5b. Please do not post any direct attacks or snide comments directed at a list member. Enthusiastic arguments are encouraged, but please keep everything cordial. Members who verbally attack another (either via the list or via direct email) will be removed from the list. As the 'official' list Cop, I'll jump in as necessary to keep everything orderly. I do this off line and occasionally to the list when it is appropriate. Our goal is to keep the Elecraft list a fun, informative central clearing house for Elecraft information and enthusiasm. 6. Please DO POST your technical questions and comments to the list. Elecraft owners are your best source for quick answers (and they NEVER sleep!) If you don't get the answers you need from the list please email us direct at [EMAIL PROTECTED] , which is our customer service address. We do try to watch the list traffic, but we may not respond to everything immediately and may miss some postings sent to the list or our personal addresses. 7. Please post your experiences

[Elecraft] Working the CQWW RTTY
I am at the beach and decided to 'play' in last weekend's rtty contest with my K2/100. I also have the KAT100 with me, and used the Rigblaster nomic as the sound card interface. I was pretty impressed with the rx in the contest. I am sure 80% of the qsos did not show any deflection on the s-meter. The usage of the KDSP2 was very positive. I set the AFIL filters to center on 1.1 Khz and did a range of bandwiths, from 800-250. After a while, I mainly used the 500 hz bandwidth filter. It was as good as the filtering in my old Icom crystal setups. I can concur with the discussion hoping that someday we could have a KFSK2 card so I did not have to manage the afsk set-up. I was disappointed to not be able to do any 40/80m rtty. The swr on both is below 1.5/1 but anything over 8 watts would cause the k2 to reset itself. Listening through the 'audio out' port on the nomic, the audio coming from the PC had a strong swoosh sound just before the reset of the K2. I suspect it must be some RF in the shack. I do not have a dummy load so I cannot accurately state the cause. I hope its stray RF. I can work cw on both bands at full power with no issue. I bought a computer fan at Staples that you normally mount in the computer case where all of the pci cards are. I clipped off the excess aluminum tabs, got a large rubber band and put it on top of the K2 to blow over the heat sink. The fan is not so noisy and I felt much better that the 50 watts were not causing any real damage. If anyone is considering any sustained psk/rtty operations, you might consider this approach. All in all, it was a positive experience. I hope to learn the cause of the 40/80m problem. Now if I just had that Elecraft power amp.. 73 de Neal k3nc ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Let me build your K2
Indeed, I was fortunately able to have the time to build my K2, but since receiving the KPA100 in early July, I got very busy at work have not yet completed it. It doesn't look as though it will be ready for the Worked All Germany contest in mid-October, which was my goal. As far as I can see, Alan is providing a really useful service to people who either are unsure of their constructional abilities or don't have enough spare time.

[Elecraft] K1 or KX1 ??? That is the question.
Whether 'tis nobler to bear the slings and arrows of outrageous propagation or with a kit end them? You guys and all this talk of kit building is making my nose twitch and my fingers itchy. The soldering station is ready, pad wet, and rosined solder to the fore. Now which shall it be? My stalwart K2/100 #2511 works quite well each Sunday afternoon and each weekday morning for its various nets and skeds. But I want another rig to carry with me on trips and campouts. I am torn between the masters (read Wayne and Eric here) other two rigs. The KX1 has great reports: heck I give them all the time during ECN. They work quite well in the hands of the best (Ray, K2HYD and Rick, KL7CW please take a bow). Seems like they can beat their way through pileups to get my attention ;) I never truly believe them when they tell me 3 watts but it must be true. I've even worked Wayne from the sandy shores of Lake Michigan while he was contesting with his KX1. However, the K1 was shown to me by Karl, N7NLU during a contest where it worked admirably from our local park. It had some very nice features which pull my attention away from the KX1. More bands are covered but it does not cover so broad a frequency range as the KX1 in each of them. I also am not sure how well it may work during cross mode contacts. But, the countersunk screws sure are enticing. Once again in the hands of a master (read Ric, VE3XL with his late, lamented K1) it shines. Some of you have solved this dilemma by building one of each. I am fairly sure Wayne and Eric do not mind this solution. Then there is the input of the holder of the purse strings. How can one sneak another kit into the house without her approval? What should I say when asked? I know she'd send a nastygram to Elecraft in a minute if my heart is not pure and my reasoning sound.

Re: [Elecraft] auto tuner
Ron group, I initially used a predecessor to the Z-11, the LDG QRP autotuner (the early version without latching relays) with my (then) basic cw K2it worked pretty welllater I added the Elecraft internal K2 autotuner ...it works a little better and is much handier (no jumper cables, no separate power supply, etc.), especially when used for portable ops.

Re: [Elecraft] auto tuner
Sorry, I failed to notice that your inquiry was about using a Z-11 with a K1.but I think my commects about using the LDG with a K2 will still apply to the K1.

Re: [Elecraft] K1 or KX1 ??? That is the question.
Based on replies I got recently, and what I have heard for a while, it seems pretty easy. If you want something really easy to grab and go, especially light camping and pedestrian mobile, go KX1. If you want something for easy mobile, camping with some extra weight and room, and for hotel duty, go K1. The K1 seems to get the nod over even the K2 with many for casual ragchewing. Many describe it as having an undescribable quality that makes it easier to listen to. Just what I have heard. I already own a KX1, which was fun to build and even enjoyed passing on feedback on the manual and build process back to Wayne and Eric. I have hemmed and hawed recently over which rig to get next, including the impressive new NorCal NC2030, but I hope to be ordering my K1 quite soon. Hope this helps.

You guys and all this talk of kit building is making my nose twitch and my fingers itchy. The soldering station is ready, pad wet, and rosined solder to the fore. Now which shall it be? My stalwart K2/100 #2511 works quite well each Sunday afternoon and each weekday morning for its various nets and skeds. But I want another rig to carry with me on trips and campouts. I am torn between the masters (read Wayne and Eric here) other two rigs. The KX1 has great reports: heck I give them all the time during ECN. They work quite well in the hands of the best (Ray, K2HYD and Rick, KL7CW please take a bow). Seems like they can beat their way through pileups to get my attention ;) I never truly believe them when they tell me 3 watts but it must be true. I've even worked Wayne from the sandy shores of Lake Michigan while he was contesting with his KX1. However, the K1 was shown to me by Karl, N7NLU during a contest where it worked admirably from our local park. It had some very nice features which pull my attention away from the KX1. More bands are covered but it does not cover so broad a frequency range as the KX1 in each of them. I also am not sure how well it may work during cross mode contacts. But, the countersunk screws sure are enticing. Once again in the hands of a master (read Ric, VE3XL with his late, lamented K1) it shines. Some of you have solved this dilemma by building one of each. I am fairly sure Wayne and Eric do not mind this solution. Then there is the input of the holder of the purse strings. How can one sneak another kit into the house without her approval? What should I say when asked? I know she'd send a nastygram to Elecraft in a minute if my heart is not pure and my reasoning sound.

RE: [Elecraft] Elecraft. G5RV Question
The G5RV may work well, but I doubt if it'd work better. For most of my Ham career my mainstay antenna has been a doublet. That's a center fed wire as long as I can make it (seldom over 150 feet since and currently only about 50 feet) and as high as I can get it. It's fed with open wire line using a balanced tuner. The efficiency is excellent, even down to the band where it's only 1/4 wavelength long overall. At that extreme it's about 1 dB below a full-size dipole. As always with a horizontal antenna, the big issue is height. For best DX it needs to be about 1/2 wavelength above the ground: easy on 20 meters where that's about 32 feet, a bit harder on 40 where it's 64 feet and pretty challenging for most ops on 80 where 1/2 wave off the ground means it needs to be 130 feet high! That's why many ops who want to chase DX on 80 go for a vertical. Less efficient on paper but still puts out more low angle radiation than most of us can manage from a low horizontal antenna. Of course, on those lower frequencies the horizontal is an excellent, high-performing short-skip or NVIS antenna providing excellent signals out to maybe 500 or even 1000 miles. My doublet at 30 feet has about 6 dB gain straight up on 40. I've worked a few Japanese and Europeans on it on 40, but most of my 40 meter contacts are in North America and my 80 meter contacts show very good signals out to 600 miles or so. On 30 and 20 it's a good DX performer that often gets me DX stations answering my CQ running my K2/100 on CW. I couldn't help but smile to see that Mike, ZL1MH reported to Kevin that I was one of the three stateside stations he could copy in New Zealand during the ECN last Sunday afternoon on 20 meters. The bottom line is that most of the designs that have become popular over the years are simply variations on either the basic doublet that I use or the basic Marconi antenna worked against ground. Some of them provide a somewhat easier range of impedances for the ATU to handle, and others, like the common center-fed 1/2 wave 'dipole' provide an easy match for cheap and easy-to-handle coaxial feed lines, albeit only on the bands where they are either 1/2 or 3/2 waves long.

[Elecraft] Tenna Dipper Kit... a small solution !
Hi, For people that do a lot of field radio operation, carrying an antenna analizer like a MFJ-259B could become anoying and also a waste of space in your luggage. We nearly always tune the antenna at the same frequency on the same band. So instead of carrying a big box, why not carrying a small box that will do this antenna ajustment... I build a Tenna Dipper from the 4SQRP Group. A pretty small kit, fun to build, like Elecraft kit. It costs almost nothing compared to a MFJ analyzer, and you will save space and weight during travel. Take a look at my photos... http://homepage.mac.com/jfmenard/PhotoAlbum48.html The website for ordering or have any info is: http://4sqrp.com/kits/ td/td.htm 73 and have a nice build time !!! = /¯\/¯\/¯\/¯\/¯\/¯\ JEAN-FRANCOIS MENARD V A 2 V Y Z \_/\_/\_/\_/\_/\_/ Elecraft K2 #4130 Elecraft KX1 #999 http://homepage.mac.com/jfmenard = ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
