That material is anything but brief, but I believe that it is quite clear and easy to study IF you understand the fundamentals of electrical circuits that include R, L, C, and Z. but the short answer is that with a coil balun, the inductance increases as the square of the number of turns. With the beads, the inductance just increases as the number of the beads. YES So, ignoring stray capacitance, You CANNOT ignore stray capacitance, it makes a VERY major contribution to the behavior of ANY choke. a toroid with 10 turns will have 10 times the inductance of the same cable passed through 10 toroids (beads). You get more bang for your buck by coiling the cable. The additional losses are not too great for most applications. YES. BUT -- it is NOT about INDUCTANCE, it is about the RESISTIVE component of the impedance. And that RESISTANCE is the loss component of the parallel RLC circuit formed by the inductance of the choke, the capacitance, and the loss coupled from the ferrite core. It is the RESISTANCE that solves our problems, NOT the inductance. We use inductance in TRANSFORMERS and in resonant circuits that are part of radios. We use RESISTANCE in RFI suppression and in common mode chokes.

Re: [Elecraft] K3 - amp plate current wiggles on fsk
Hi Dave: I made a few contacts in the cqww rtty today with a K3. Everything seemed to work fb, but I noticed the amplifier plate current wiggling with FSK modulation. I never noticed this with my old TS-850. I hooked up a hand key to the K3 FSK jack, and when the key went down, there was a short power excursion upwards. When the key went up, there was a short power excursion downwards. The final power was the same after these excursions settled out (about 0.5 second). The power excursions were about 100 watts out of 1500. Operationally this is no big deal, but I wonder if there are transients being generated. Has anyone else noticed this? Yesterday afternoon, I decided to give a CQWW RTTY Q to a local (W4RK) who had been toiling long and hard in the contest. I don't have ANY(!) RTTY software on hand, so I programmed the K3's M1 and M2 with an answer to someone's CQ (M1) and the appropriate exchange (M2), and then send the station's call in CW, using the CW-to-RTTY conversion facility. I was driving my Alpha 76PA to about 700W output with about 25W from the K3. I noticed no(!) variation output of the amp at any time during the 50 (or so) Q's I made (in order to ensure that's I'd not appear as a UNIQUE in W4RK's log). I was working stations as fast as I could tune 'em in and ID the decoded call...! I watched the RF output envelope closely on an SM-220 monitor scope AND on an LP-100A wattmeter (from N8LP, thanks Larry). No RX-to-RX or TX-to-RX anomalies were noted. I operated on both 20M and 15M. Oh... I never did find W4RK to give him that QSO... turns out that while I was looking for him, he was outside, working on the house... heheheh!

Hi, my K3 has always done this, and is, as far as I am concerned, part of its personality. The couple of watts bounciness has never caused any problems.

Re: [Elecraft] Line In problem ...
I've simply tacked a jumper around L4 at the present time and will decide on a permanent fix later. The more important question is why L4 would fail at all? Joe, Possibly a high DC offset from the external sound device or an accidentally high AC audio level at the KIO3's LINE IN jack. If for example a sound card produced a high DC offset from it's LINE OUT jack that were present on the K3's LINE IN connector, then I could see where L4 could possibly fail. At least as far as I can see in the K3 schematics, there's presently no coupling cap as part of the KIO3's LINE IN circuit Since R13 (T1's series input R) limits the LINE IN current, it would take a substantial DC offset (or very high AC audio level) to cause L4 to fail. If DC was the root-cause, then one possibility to avert an occurrence in the future is the placement of a 4.7uF coupling cap ahead of the KIO3's LINE IN jack -- or in the alternative, between the KIO3 LINE IN jack and T1. With this cap value, the R13 series build-out R, together with the T1 primary would present a -3dB turnover point of ~ 30 Hz when driven from an external sound device with a low-Z output. OTOH, perhaps L4 was on the ragged-edge of failing as a defective component anyway. Anyone know a way to autopsy an SMT inductor? g Paul, W9AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Elecraft Rigs in Emergency Service...
Several years ago (10+) during a contest, probably phone sweepstakes, I heard a marine emergency calling and calling. I first thought it was somebody messing around, BAD IDEA. After I listened for a couple of minutes, I believed it. The contesters were ignoring it or not hearing it and I tried to talk to the guy but couldn't hear him reliably because of the contest and finally asked several times to please clear the frequency because of a marine emergency and gladly it happened. I still had trouble hearing everything he was saying and asked if anyone else had a better copy than I did. One of the big stations came on and took it over, got the information of his location and that he was dead in the water, called it in, and went back to him and told him that it had been reported and that they were on the way. He wasn't using SOS and do not recall if he used anything else or not as I have never heard of pan pan or QRRR until now. I am a new ham and it wouldn't have meant a thing to me. He was just calling for help, repeatedly, and describing his situation and requesting somebody to make a call for him.

Re: [Elecraft] KAT3 settings saved per band
Steve, The KAT3 does remember the last tuned settings for each band and each antenna. In the case of an external manual tuner, it is easy to set the manual tuner to the approximate correct settings for each band and then use the internal tuner refine the final match. No need to use the bypass setting. An SWR less than 2.0 for a short run of coax will have insignificant loss. Those with remote auto-tuners cannot use that approach, but it works great with manual tuners. Those with remote auto-tuners or a linear, read below for one way to address that situation. Tuning one of the ANTx jacks into a dummy load is one way to make an effective BYPASS, since tuning into a dummy load will set the ATU for a 50 ohm match. Then just use TUNE (hold XMIT) instead of ATU TUNE for tuning of the remote auto-tuner (keeps from modifying the internal tuner settings). The config menu allows you to set the power level for TUNE separately from the fixed low power level used for ATU TUNE. The same technique works for those using an amplifier - do an ATX TUNE into a dummy load, and then do not use ATX TUNE again when that antenna output is selected. The KAT3 operation may not be the same as that in other transceivers, but with the availability of both TUNE and ATX TUNE, it can be even more versatile. 73, Don W3FPR [EMAIL PROTECTED] wrote: I use two doublet antennas, one hooked to ANT1 through a balun for 40M which uses the KAT3 tuner, and a second (ANT2) in which I bypass the KAT3 and use an external Palstar BT1500A balanced tuner for 30-10M.

[Elecraft] CQWW RTTY - K3 Experience
I worked the CQWW RTTY contest last weekend. After nearly 30 years of amateur radio operating, I have never had more than a handful of RTTY QSOs so I struggled from the start with accepted contest procedures and also the rig set-up necessary to maximise copy of the wanted signals and the rejection of adjacent signals. I cracked the procedures quite quickly but the copy problems continued for some hours until I cracked the filter set-up. Once I set the high and low cuts to just past the mark/space tones it was so simple and I posted 260k+ points easily. I have the filter shape settings for this type of contesting saved now. Another problem for me was the line input from my pc for the tones was set at '3', anything more and the whole thing over modulated and caused my linear to pop, especially on 80m. Having said how flawlessly the K3 performed, it was complemented by N1MM's cracking software which does just about everything for you. Whether I was running or SP the only effort required was turning the VFO and clicking the mouse - easy contesting! (Oh dear! Another marketing slogan from me - sorry). I'm looking forward to seeing how this set-up works in the SSB and cw legs over the next couple of months.

RE: [Elecraft] Toroids frequency range and baluns
Hi Bob, See comments interspersed. On Mon, 29 Sep 2008 09:51:11 -0500, Solosko, Robert B \(Bob\) wrote: Jim, I've been reading through your tutorial, and, if I understand it, the best approach is neither a plain wound coax balun nor a string of ferrite beads strung on the coax but is a balun made with coax wound around a ferrite core in a way the minimizes capacitance - is that correct? It depends mostly on the frequency range and the ferrite material, and to a lesser extent, on the power level. Think of the choke you're winding as any other inductor that has VERY low Q (typically around 0.5), and thus a very broad resonance. Like any inductor, we vary the number of turns, their diameter and spacing, and the core material to hit the desired resonance. A choke of #31 material can provide a strongly resistive impedance over a frequency range of roughly 4:1, so we can wind one to cover 160-40 meters. That choke would use closely spaced turns, because we need the additional capacitance and mutual coupling between windings to move the resonance down to about 80 meters. On the other hand, a choke to cover 20-10 meters needs wide-spaced windings, because we only want to move the resonance to about 21 MHz. Power level enters the equation only to the extent that the choke must provide sufficient common mode impedance that it reduces common mode current to the extent that the P=I*E is small enough that it does not overheat the coax or the core. The tutorial shows that's an easily achievable objective once you realize that it's a key design parameter. But I still have several more questions: - it appears that material 31 is the best material to use for baluns. It's the best material to use for a COAXIAL CHOKE that needs to work below 5 MHz. #43 is equally good on 40M, and slightly better above 40M. If you're only stocking up on one material and buying in quantity for the best price, # 31 is the best choice. In addition to my transmission line balun, I also have some problems with power supply birdies on 160m, and to a lesser degree on 80m. Is material 31 still the optimum material for adding additional RFI filtering to my power supply (along with parallel capacitors)? These chokes kill common mode current on the cable you wind around them, but there can also be differential mode coupling that a capacitor ACROSS the line (that is, plut to minus) can suppress, and there can be direct radiation from insffficiently shielded circuitry. No external filtering will kill (or change) that direct radiation. - My transmission line balun is serving two purposes: as a current balun to reduce the RFI in the shack problem that I have had, and as a 4:1 transformer to better match the ladder line from my antenna to the short length of coax to my rig. (My 4:1 balun is made from 2 separate cores as is the BL2, but they're much larger cores to minimize saturation and heating problems.) It seems to me, if I understand your tutorial, that the characteristics of the cores used for transformers (low resistance) and those used for suppression (high resistance) and mutually exclusive. Thus, does it make sense to have a single balun serving these two purposes, or is it better to optimize the balun for the transformer application (material ??) and have a separate balun optimized for suppression? That's a very perceptive question. For the first part of the answer, study the photo of the high power DXE 4:1 balun in my Power Point presentation -- select it from http://audiosystemsgroup.com/publish That balun is essentially two chokes wound with parallel wire transmission line (that is, bifilar) around what could be #31 or #43 cores. On the 50 ohm side, they're wired in parallel, on the 200 ohm side they're in series. Because the chokes are bifilar, there's a lot of leakage flux in that core if you're running power. The choking impedance isn't very high either. A far better design would use coax, #31, and a lot more turns. That balun would have a much higher choking impedance, and would also be a lot more efficient. The second part of the answer is to study the DXE catalog -- they sell a separate product that they call a common mode choke! When you study my measurements (in the Power Point) for three of their high power baluns, it's obvious why -- they have very poor common mode rejection. So the short answer to your question is, YES! Another point of clarification. Both the DXE two-choke series/parallel combo and the one I described wound with coax are NOT transformers -- they are NOT coupling signal through the core, they are using the core to form a choke. They ARE doing impedance transformation and balancing. So it is correct to call them baluns but incorrect to call them transformers. 73, Jim K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It is a function of how N1MM sends CW -- it runs a separate program that hogs the processor, so that almost nothing else can happen on the computer while you're sending CW! I'd call that bad programming, but what do I know. :) I raised this issue, and N2IC, one of the guys who has contributed to N1MM, attempted a fix. I beta-tested the code on my 5-year old 1.1 GHz IBM T22 running SO2R during a recent NA Sprint. It worked, I could interrupt sending, I could shift focus from one radio to another, but the CW could best be described as lumbering -- that is, sort of choppy. Much better -- it's stable, no crashes -- but not ready for prime time. That software works FLAWLESSLY for a SINGLE radio, including a K3, MP, Omni V, and TS850 with CW and PTT on the same cable -- in fact, I've done that for five years with both WriteLog and N1MM on that same T22. It's only SO2R that chokes it, and it's the way that N1MM (and probably WL) send CW. That's why so many guys doing SO2R use the WinKey -- it takes keying outside the computer. So as far as I can tell, it has NOTHING to do with the K3, and the programmers should not need a K3 to solve the problem. They just need to find a better way for computers to generate CW. Since I'm not a programmer, I have no idea how much of a challenge that is. The sad thing though is that the N1MM programmers SEEM to have abandoned the idea. If you want to use N1MM and run SO2R, you should voice your concerns to them. 73, Jim K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Elecraft Rigs in Emergency Service...
Often plain language is best. The special calls are for *trained* operators who recognize them quickly even buried in QRM. Every marine or aircraft operator will tell you there's nothing more arresting than suddenly hearing SOS pounded out in Morse or Mayday on voice. Even listening to playback of a distress call makes my skin crawl. You know there someone in mortal danger at the other end of the message. But that's true only if you know what the call means. I'm deeply sorry to hear about the Amateur operators who clearly couldn't be bothered with a distress call until they were asked. They are not qualified to be Hams and should have lost their licenses. Ron AC7AC -Original Message- Several years ago (10+) during a contest, probably phone sweepstakes, I heard a marine emergency calling and calling. I first thought it was somebody messing around, BAD IDEA. After I listened for a couple of minutes, I believed it. The contesters were ignoring it or not hearing it and I tried to talk to the guy but couldn't hear him reliably because of the contest and finally asked several times to please clear the frequency because of a marine emergency and gladly it happened. I still had trouble hearing everything he was saying and asked if anyone else had a better copy than I did. One of the big stations came on and took it over, got the information of his location and that he was dead in the water, called it in, and went back to him and told him that it had been reported and that they were on the way. He wasn't using SOS and do not recall if he used anything else or not as I have never heard of pan pan or QRRR until now. I am a new ham and it wouldn't have meant a thing to me. He was just calling for help, repeatedly, and describing his situation and requesting somebody to make a call for him.

RE: [Elecraft] Elecraft Rigs in Emergency Service...
Good going Keith! An experienced operator would have closed the loop for you with a service message informing you of the outcome. I've relayed such traffic and the first thing the fire service wants to know is where the person who reported it is located. They want to confirm that he/she is not in the danger zone and the status of any others in the area. (Even if not in the fire danger zone, many people don't realized a fire drives all the wildlife away from it. I've heard of people watching a fire from a 'safe' distance when suddenly bear, cougar and lots of other animals not particularly friendly to humans come charging right at them.) The RACES manuals say how to handle emergency traffic in the Amateur Service. Basically, you reply adding SVC to the message number when closing the loop with the originator. It presumes a *written* message. Special forms aren't needed. It's strongly recommended Hams know how to properly format messages on a plain piece of paper. Even if the originating station in the middle of the emergency doesn't take the time to write one, the relaying station should to make a written, time-stamped record of the exact contents of the exchange in a message format. Most commercial licenses in the USA (radiotelegraph, radiotelephone, GMDSS, etc.) require the applicant to demonstrate how to behave when involved in emergency communications even though a person might spend a lifetime operating without using it. It sounds to me like the Amateur licenses should require the same.

I asked him to contact authorities to report a fire and he said OK. That was it. I have no idea if the fire got reported or anything. It left me feeling very unsatisfied. I suspect, however the fire was already known about. - Keith N1AS - - K3 711 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] CQWW RTTY - K3 Experience
Ran barefoot here, into a dipole at 40'. 2 stereo cables, a serial cable (for band info) and ran in VOX mode. 420 Qs, 235,296 pts. Only my 3rd RTTY contest. I had never done it at all before getting my K3 in March. David Wilburn NM4M http://www.nm4m.com G4MKP wrote: I worked the CQWW RTTY contest last weekend. After nearly 30 years of amateur radio operating, I have never had more than a handful of RTTY QSOs so I struggled from the start with accepted contest procedures and also the rig set-up necessary to maximise copy of the wanted signals and the rejection of adjacent signals. I cracked the procedures quite quickly but the copy problems continued for some hours until I cracked the filter set-up. Once I set the high and low cuts to just past the mark/space tones it was so simple and I posted 260k+ points easily. I have the filter shape settings for this type of contesting saved now. Another problem for me was the line input from my pc for the tones was set at ‘3’, anything more and the whole thing over modulated and caused my linear to pop, especially on 80m. Having said how flawlessly the K3 performed, it was complemented by N1MM’s cracking software which does just about everything for you. Whether I was running or SP the only effort required was turning the VFO and clicking the mouse – easy contesting! (Oh dear! Another marketing slogan from me – sorry). I’m looking forward to seeing how this set-up works in the SSB and cw legs over the next couple of months.

RE: [Elecraft] K3 - interfacing to N1MM Contest Logging software
At a wild guess (since I've never used the program) they are running something at a high priority in order to try to overcome Windows innate inability to do accurate high speed timing. That is correct. With SO2R the logging programs must run their CW timing at high priority in a separate process or Window's non-realtime nature will severely screw up the timing. It is the lack of Windows' ability to handle real-time events and the lack of common PC hardware to provide an independent clock that is at fault here. WinKey is the only transceiver independent way to get that timing outside of Windows where it is not effected by the vagaries of Windows (or any other operating system). Unfortunately as has been pointed out on two previous occasions when I have questioned why it is not used, the trouble is that the K2 and K3 are the only radios that implement this in a properly thought-out way, so developers of general purpose software are not interested in doing the necessary work to exploit it. First, the Kenwood TS-480, 570, 870, 2000 also support the KY command. However, KY is not properly thought out and lacks several features - most notably the ability to edit portions of a message that have already been sent to the external device.

There is no reason why a highly accurate background thread cannot be implemented in a Windows NT-based system for sending CW where the solution does not use all CPU or affect other programs which are running, it's up to the programmer to code properly. There are several problems ... first, most of these developers insist on maintaining support for Windows 98 (although I think Win 98 users should be left to fend for themselves along with any DOS users who might still be hanging on). Second, no programmer can protect against poor programming by other programmers and the bloatware that gets installed as part of other software (auto stat/auto update/auto config, etc.) on many computers unknown to the user. Finally, too many users insist on using ancient (PIII/450 MHz with 256 MB RAM) hardware that is just not up to the task and destroys performance due to memory paging issues. WinKey is the very best option IMO. We agree. Since the serial WinKeyer 2 kit which is available for $36 from K1EL can be extended to full two radio support with two FETs, two resistors and two capacitors, I don't see any reason for the resistance by so many.

That's also why a kept going on with the 5nn instead of 599. Next time load your memory with 599 14 IM (dididahdah with no space between). The IM is for IMmediate end of transmission. Don't send 5NN since 599 is just as fast in RTTY and less confusing to RTTY ops. Using my paddle, I loaded: M1: W4ZV W4ZV IM M3: 599 05 NC IM (if I needed linked repetitions I just double-tapped M1 or M3). Using the memories, I was later told I sounded like regular RTTY (i.e. no delays due to CW sending speed since my memory exchanges were sent at full RTTY speed of ~60 WPM). I didn't see any point in repeating the call of the other station since I was always dead zero beat (thanks to CWT) and was responding to his CQ (i.e. not CQ-ing myself). I found the K3's CW TX decoder more sensitive to perfect CW timing than my poor fist, so after mangling my first QSO with the key I used the memories exclusively for my other QSOs. I tuned for a CQ, pressed M1, if answered I pressed M3, got my confirmation and went looking for another. My only slight confusion was when my call would appear in the buffer after answering a station. The first time I thought that was the station answering me but quickly realized it was left over in the display from my call (i.e. M1) since the DX often answered someone else in the pileup. This was my first experience with RTTY after 51 years on the air. I would never have bothered were it not for the K3. I now feel very comfortable using the above technique to call DX stations in a pileup, should the need ever arise (i.e. in case a new one should show up on RTTY and not CW). 73, Bill -- View this message in context: http://n2.nabble.com/CQWW-RTTY---K3-Experience-tp1126034p1127632.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re[Elecraft] ceived My K3
It has arrived!!! I placed my order in the beginning of February and it came Thursday, September 25. I even got a picture of the UPS guy carrying over the box. The reason why it took so long was I had to wait for the sub receiver which was on back order and I wanted them to install it. Every time I put something together, I always lose screws, spill drinks, step on parts running to get the door, ect. ect. Strange, I didn't have to sign for it. If I wasn't home, I guess it would be in plane view in front of the door. I could not believe I was up 24 hours having fun learning the functions of the new radio. I still have a long way to go. I was even more surprised how easy it was downloading the software into the radio and opening it up for MARS. Very easy! I got on the MARS Nets right away. I had a couple questions and Elecraft was very helpful. Thanks Scott and Dale for the patience with someone from old school.! I bet they had a good laugh but they walked me through the computer software and helped me understand the settings which were shot into the radio. I also can't believe how it really cuts down the line noise around the neighborhood. I don't want to bother Dale or Scott too much so I guess I will be posting on here if I don't understand something. The hand mic I received seems to give better audio than the three studio mics I have laying around and it seems sharper but I really do need a good desk mic that sounds good. (I am afraid that I'll drop the hand mic in my super big gulp cup.) If anyone has good EQ settings, please respond with those values. Well, that's all for now.

Re: [Elecraft] [K2] Tuning During Repeat Memory Sending
The K2 cannot tune while in transmit mode. It takes a bit of time for the K2 to restore to RX mode (as far as the firmware is concerned).

Tell your MARS director before you fill out the application that your K3 can be modified for MARS and that you can't modify the radio until you get your MARS call sign and credentials to send to Elecraft. In the mean time, you can be studying the MARS manual. I am sure your MARS director will have a better understanding of whats going on and he will instruct what to put in the application regarding if your radio is opened for MARS. See you on the bands. Michael Fox (K5MEF) wrote: Is anyone using the K3 for MARS work? If so, can you contact me off-list to provide more info? I'm interested in getting involved with MARS. But the application simply asks if you're able to transmit/receive on MARS frequencies without specifying what those frequencies are. So, I'd like to know what frequencies I need to worry about and what, if any, modifications are needed to the K3 to make it able to participate in MARS work. Thanks in advance. 73, Michael - K5MEF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] CQWW RTTY - K3 Experience
Yes Bill, I used the IM during paddling and using the memories. If using the paddle, be sure to really send ..-- A bit too slow with the paddle and it sends IM. :-) The high speed of the memories: good idea! Implented for next time. 73 Arie PA3A - Next time load your memory with 599 14 IM (dididahdah with no space between). The IM is for IMmediate end of transmission. Don't send 5NN since 599 is just as fast in RTTY and less confusing to RTTY ops. Using my paddle, I loaded: M1: W4ZV W4ZV IM M3: 599 05 NC IM (if I needed linked repetitions I just double-tapped M1 or M3). Using the memories, I was later told I sounded like regular RTTY (i.e. no delays due to CW sending speed since my memory exchanges were sent at full RTTY speed of ~60 WPM). ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
