I can't speak for the test conditions used here, but for an independent comparison of most ham transceivers, see: http://www.sherweng.com/table.html Sherwood sorts his table by 2-kHz (close-spaced) dynamic range. The K3 and FT5000 have the top spots. I'm still not entirely sure why Rob put the FT-5000 above the K3, given that they tied on narrow-banded IMDDR3 and the K3 had the better numbers in nearly all other categories.

[Elecraft] Website request
Eric, If possible would you please make the 'Elecraft' text at the top of your web pages an active link back to the Elecraft homepage? I've grown accustomed to this on many other commercial websites and appreciate the shortcut it offers. I'm referring to the brand name object above the webpage titles like what's seen on your Document and Software Download Page, Software Page, and your Price List and Order Page. I realize there is an 'Elecraft Home' link near the bottom of some pages but it seems to take a bit longer to find whereas the big brand name at the top is quick and easy to locate on every webpage that has it. Thank you Eric. 73, Gary N6LRV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] P3SVGA Question
Hi Toby, What you describe is not what I am seeing on my P3/P3SVGA scope. On the P3 screen with P3 Span set to 5 KHz the Green bandwidth display (Bar or U ) varies in width proportional to the K3 bandwidth setting. It is still visible with bandwidth set to a minimum of 50 Hz. The exact same Bar Display is duplicated on the P3SVGA display. What you are experiencing does not sound normal. Perhaps a P3 guru can shed some light on what you are experiencing.

Re: [Elecraft] Koss Headsets for the K3 (Was: Re: Yamaha CM500
Final post on my quest for the ultimate headset for my K3. First, a TON of thanks to Lu, W4LT. His step-by-step for replacing the mic housing on the SB40 with the housing from a Heil BM10 was first rate! Here's what I ended up doing. I replaced the microphone housing on the SB40 with a microphone housing from a broken Heil BM10. Heil still sells the housings and windscreens. In place of the crappy SB40 dynamic mic element I replaced it with a Heil HC5 that a friend had. It's a pity that Heil no longer sells the HC4 and HC5 elements separately. Ask around though...you'll find someone that has one laying around. In doing the above mods to the SB40 you end up with a VERY comfortable headset with a great sounding mic element. I just could not get the stock SB40 element to sound good. The HC5 rocks. By the way, I don't own a Yamaha CM500 but others have said it is identical to the SB40 except for the CM500 has an electret element and requires bias. On 3/17/2012 11:50 AM, Lu Romero wrote: Gary: I own both a Koss SB40 and two Yamaha CM500'ds. The Koss and the Yamaha are exactly identical, save for one thing... The microphone capsule. The Koss SB40 has a dynamic capsule while the Yamaha CM500 has a electret condenser capsule. Other than that, the headsets are exactly identical in every detail except for the name. Probably made in the same Chinese jobber. But here is where the simialarity ends: The Yamaha electrect capsule is flat and can be made to sound really great on the K3. The Koss dynamic capsule is all bass, very mushy, and has low output. Even engaging the K3 equalizers and tweaking a lot, I could not make my SB40 sound very good at all. The capsule just sounds ugly. The fix for this is to remove the two screws that hold the capsule on the SB40's boom and remove the offending microphone that looks surprisingly like a cheap Chinese dynamic earphone (its actually the same exact size as a IPod headset element and looks identical!) and replace it. In my case, I had an old Heil BM-5 with a bad earpiece but a perfectly good DX4 capsule. I removed the plastic mic holder from the rigid Heil boom, and with a slight widening of the boom inlet with a Dremel tool, it fits right on to the SB40 boom! Solder up the existing wires from the Koss mic and you have a wonderfully comfortable headset with a very flexible boom that, in my case, works great on my secondary Kenwood TS570 rig. Of course, YMMV, but it works for me here!

I looked at the SB49 first. (The SB45 is identical to the SB49 but without the volume control in the cord). I didn't really like the way the SB49 fit. It's a very subjective thing but comfort was what I was looking for. The other thing I didn't like was the flexible boom for the microphone was very whippy. It was almost like a wet noodle. Not good. Next I looked at the SB40. The fit was great and very comfortable for the 5 minutes I wore it. The mic boom was stiffer too. The SB40 has a dynamic mic element. I ended up buying the SB40. The price was $39.00 plus sales tax. I was all set to buy a Yamaha CM500 but I really wanted to see how they fit first. I looked at a couple places and couldn't find a local store that had the CM500. For this reason I look at Koss. The other thing Koss has going for it is the limited lifetime warranty. Being that I live near the factory this is a big advantage. Second is that I've owned other Koss products and have always been very happy with them. As I said I've never used the Yamaha CM500 but the Koss SB40 looks very similar. I'm also kind of a headphone junkie. With the K3 I figure that most modern headsets have much more performance (frequency response, etc) than one needs for communication. So they are all pretty much up to the task. Same for the microphone. With the TX and RX Eq features of the K3 I decided to concentrate on fit and comfort. I think that juist about any headset and microphone can be made to sound good. I haven't used the SB40's yet but will report back once I've played with them a bit.

Re: [Elecraft] filters and contests and interference question/opinions
Thanks for all the replies. I did forget about playing with the AGC so I went back and did some adjustments and was able to make things better. I think that the problem is that there is too much junk in the passband during contests and asking the dsp to take it all out just does not work. So I think that I will be looking for either a 1.8 or 1.5 filter. I did pay attention to the pc screen to see how wide I was running the filter and most of the time I was below 1.8 in width and a fair amount at 1.4 to try and reduce the splatter. Thus until I have more filters to play with I wont know for sure.

Re: [Elecraft] cable management
I have a good handle on my coax cables. I use a MFJ-4726/RC which has 6-inputs and 6-outputs, and can be placed under the bench as the switching is handled with a small remote control box. But for the rat's nest behind the radios for all the other interconnects, all I did was label the individual cables using Casio black-on-white labeling tape. I also labeled all coax cables attached to the MFJ-4726 using a Sharpie silver permananent marker as I could write directly on the black coax covering.

Re: [Elecraft] [Elecraft_K3] Re: Unfair Comparison?
I agree with a previous post that the price difference between an equally equiped K3 and a FT-5K is very close if none. I did the price comparison before buying the K3 and what really made decide for the K3 instead of the FT-5K was Elecraft's great customer service and the fact that I didn't have an immediate need for features like the second receiver and the 200 watts, thus saving some money. I also do believe that the K3 receiver is out of this world specially on the implementation of the digital NR. My SO2R second radio is a TS-590 and which I believe is the best bang for the buck for a DX'er/contester who doesn't want to spend more than $2K on a radio. In my opinion,it's unfair to compare a K3 with a TS-590 simply because they are in different price class. I paid near $1,700 for my TS-590 wheras my almost plain K3 costed me near $2,600 last December and it doesn't include some options the TS-590 includes like ATU, FM, AM and general coverage receiver. Does the K3 have a better receiver than the TS-590?, darn yeah!...much superior I would say and that's what I expected. Otherwise I would have two TS-590 sitting on my desk today with $1K+ (I intend to get the ATU option soon) to spare in my pocket. Therefore, the K3 is in my opinion in the same class as the FT-5K.

It is a good and tight filter while still bringing in some good audio. I used that same 1.8kHz Inrad filter in the old FT-1000MP, where it was very much needed for SSB contesting. Because that filter is also compatible with the K3, I decided to make a new adapter board and try it... and am very glad I did! The K3 is configured to switch in the filter at a DSP bandwidth of 1.9kHz, and with the center frequency set to 1.25kHz it gives a very good balance between selectivity and intelligibility - so good, in fact, that the SHIFT and WIDTH controls hardly ever need to be touched for the duration of an entire contest. That isn't just one person's opinion; my wife and guest operators also find those same filter settings immediately comfortable, so they can go straight ahead and operate. You won't be displeased. I agree with Dale.

[Elecraft] Orange Screen of Death
Today, while very casually operating WPX looking for new DXCC countries, my K3 went deaf and dumb. I had just switched bands and push the Tune button to adjust my antenna tuner. The radio started emitting a series of high pitched beeps (obviously the transmit output for tuning). I could not get it out of the Tune mode. I had to push the power button to turn the radio off. When I turned the radio back on, the LED's on the knobs next to the VFO cycled on for a second, then went off; the display was totally blank except for the orange background color. No controls functioned and there was absolutely no audio output. I could not turn the radio off except by turning off the external power supply. I tried to restart the radio several times with no success. I let the K3 cool down for an hour to see if it was heat related; no luck. Has anyone else experienced this or have any ideas what might be happening?

Re: [Elecraft] anyone running HRD with Signalink K3 help
The K3 also does fine on sound card modes with the VOX. (If I can remember to turn it on/off when I switch between data and SSB.) Even if you want to run with wired keying, you can turn on VOX to see if your keying connection is set up correctly. If the transmitter keys when your computer sends sound in VOX mode, but not with the wire, then the problem is in the wire/computer control (or the VOX level config).

[Elecraft] K2: Excessive ALC on Sideband
I've just recently started using phone on my K2/100 (s/n 6550) and I've noticed that even at an SSbA setting of 1, I'm getting a lot of ALC (3-7 bars when I talk in what I believe to be a normal voice). I'm using an Elecraft MH-2 mic. I checked the wiring for the mic last night and I believe it is correct. I also notice that the problem is worse on lower bands than on higher bands. I've been operating the radio at about 80 watts on phone. That's consistent with my experience in digital modes, where I have to turn the output of my computer down to around 20% and keep the TX control of my Signalink turned down to around 2/10ths (the 9 o'clock position). I have checked the jumper settings in my Signalink to make sure I'm not using the special jumper for increased gain on Tx. I operate the radio at 30 watts on digital modes. The KSB2 manual says that the value of R15 can be changed to increase the attenuation on SSbA. What kind of values should I be thinking of? Are there any other adjustments I can/should make to improve the situation? I caught some comment in a post a few years ago about there being an issue with the KSB2 on lower bands and mention of their being a fix, but I'm not sure what to search for in the archives (or rather, the terms I was searching for didn't give me anything that seemed relevant).

I tried another cable with no luck. Is there some menu item that needs to be set in order for this communication to happen?

My thoughts are that the dsp would work much better if some of the interference can be directly blocked out by the filter.

I am curious about others who may have tried these and if they kept them or if they thought it made no difference at all. The answer is...it depends. :-) I believe you're fairly new to radio and contesting. Therefore I'm assuming you mostly tune for DX stations and call them rather than running a pileup yourself, which requires good antennas and high power on SSB. For DXing or Search and Pounce (SP) contesting, you normally have plenty of time to tune in stations carefully before calling. In this case narrow filters (either XFIL or DSP) will work even with bandwidths down to 1.5 kHz. BUT...this assumes you have time to carefully tune in the station you want to call. In the case of someone running a pileup at fairly high rates (e.g. 150-200 per hour), it's a different situation. You want to copy callers correctly the first time without any tuning, send your exchange and get his exchange in the space of 15 seconds and go on to the next one. The problem with extremely narrow SSB filters is that many callers will be slightly off frequency (e.g. 100 Hz) which renders them unintelligible when using narrow filters. With a little wider filter, your ears can still copy the off-frequency guys without needing to touch the VFO. I had a 1.8k filter in the CQ WW last October and gave up using it because of this problem...and a 1.5k would be even worse. Instead I found myself using a DSP setting of 2.0-2.1k with the stock 2.7k XFIL, so after the contest I traded my 1.8k XFIL for a 2.1k. Unfortunately conditions on my favorite SSB band (10m) have been so poor that I opted not to enter the ARRL DX SSB or CQ WPX SSB and really haven't had a chance to try it under fire, but I believe it will be better than the 1.8k for my purposes. As Don said earlier, the major advantage of a narrow XFIL is to prevent AGC pumping from strong stations nearby. In extremely crowded contests this can be a major problem. However a narrower filter WILL NOT remove the splatter from nearby stations...nothing can do that short of using phased antennas to null their signal. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/filters-and-contests-and-interference-question-opinions-tp7403392p7404470.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] cable management
The most amazing station I've seen in terms of cable management is the DR1A M/M station. It's what you'd expect from German engineering. Every band had its own room with a radio and destop amp and all fed into their amp room with monoband, homebrew amps. There was not an exposed cable to be seen anywhere. Everything ran through metal conduit between rooms.

Re: [Elecraft] filters and contests and interference question/opinions
Hi Don, Every now and then on this subject, I have to throw in this rather significant (IMHO) caveat on all this talk about how good the DSP bandwidth is. I have an old MP, INRAD 8 pole filters in 8 and 455 IF's, that has selectivity just barely matched by a K3 with 8 pole roofing filter AND DSP set for skirt alignment. The DSP by itself is nowhere near the MP's selectivity, sorry. Not close. There is a point in CW contesting, where if you want to continue on a run frequency, you will have to be able to deal with a MUCH louder signal just a few hundred Hz up or down, and try to copy a MUCH weaker signal in band. And since the K3 is so clean in matters intermod, it really IS possible to deal with a 35 over 9 signal just up and copy an S1 signal in band, a mere 80 dB difference. IF you also want the desired signal to be 20 dB louder than the undesired signal in the audio, you are trying to create a separation of 100 dB !! IF you also want to be able to hear the forever present off-frequency callers, who to be kind, may actually be physically incapable of closely matching two tones (quite common actually), or to not be kind, don't have enough sense to listen first off a packet spot... if all of these, you will NOT be able to narrow down to super narrow to get rid of Mr 35over9 without giving up on all the +/- callers. Once you have figured out that 1/4 of all your contacts are off frequency then you have to maintain a barely adequate bandwidth. In my experience that is done using the 8 pole 250 roofing filter (really 330), and very carefully aligning the offset in setup, so that the roofing filter skirts are centered on the DSP skirts with width at 350, MEASURING AT THE -30 dB POINTS ON BOTH SIDES. This produces a remarkably sharp, very steep skirt, that equals the remarkable selectivity of my MP with INRAD 400 and 250 8 pole filters in the 8 and 455 IF's. Of course the MP never had the IMD performance. With aligned skirts, the K3 delivers the selectivity of the MP WITHOUT the 6 dB of IMD crud down at the bottom covering up 6 dB of Russians on 40 meters. And then there's key click cancelling, see below. With the shift control set for 10 Hz increments, Mr 35over9 can be edged out with just a tick or two up or down on the shift, and STILL have enough band width to get the other 25% of the callers. You will not accomplish this on a good antenna without a roofing filter that matches your preferred operating bandwidth. For those who can't stand key clicks, this procedure has another benefit. This very sharp combination skirt turns a key click from up or down into an amplitude-reduced very sharp waveform that has a very quick onset and very quick drop out, e.g. a ** PULSE **. Because the AGC can now reach down farther, some mistakenly think this is making the click WORSE. But it's only turned the click into a REDUCED AMPLITUDE pulse. The K3 is WONDERFUL at dealing with pulses, so the DSP NB settings of T1-7 T2-7 and T3-7, IF NB **off**, with AGC set to skip pulses, kills the clicks from the guy up above or down below. The K3 is the only radio I know of that can deal with serious clicks and maintain a satisfactory run frequency bandwidth in such ghastly conditions. But you CANNOT do this just with the DSP bandwidth. You need a matching 8 pole roofing filter with offset adjusted to make roofing and DSP skirts align 30 dB down. That said, conversational use outside of contests, where you don't have super signals just up and down, you might be hard pressed to hear the pumping, even using the 5 pole standard 2.7 filter on CW. The DSP AGC will suck up a lot of the hardware variation if you are on FAST AGC and don't run PRE on and RF gain wide open all the time on low bands. 73, Guy. On Sun, Mar 25, 2012 at 8:53 AM, Don Wilhelm w3...@embarqmail.com wrote: Don, The DSP filters can deal with all the interference as long as it is not overloaded - and overload is what the Hardware AGC prevents. What I am saying is - turn Hi-Cut down so you have the equal of a 1.8 or 1.5 filter - then if you begin to hear the Hardware AGC pumping from the nearby signals, you can conclude you need one of the narrow filters. The DSP filters do not need any filtering help, they are quite good all by themselves, but observe for AGC pumping, and if present under your contest conditions, then the only cure is a more narrow roofing filter. 73, Don W3FPR On 3/25/2012 8:33 AM, gold...@charter.net wrote: After spending time in two DX contasts this year and also dealing with lots of splatter from other stations during non contest conditions I find myself continually dialing down tighter and tighter filter settings on phone (ssb) Currently I have a 2.7, and 2.1 filter plus the narrow ones for digital.

[Elecraft] P3SVGA problem immediately upon installation

Current state (post-P3SVGA install) K3 Firmware: No changes P3 Firmware: MCU 1.12 The K3 shows normal expected S-unit levels. In order to show background noise on the P3, I have to adjust the reference level very low. My guess is that it is showing at about -9 S-units. Local AM radio station shows on K3 as S-9 +40 dB ; P3 shows it at S4. This is on both the P3 display and the flat panel display. They are talking to each other OK; it's just the levels that are extremely attenuated.

Re: [Elecraft] K2: Excessive ALC on Sideband
Jon, It is normal to have more TX RF Gain on 80/40 meters than on the higher bands. It is the gain through the transmit stages and will vary with frequency. The ALC circuits on the KSB2 board normally handle that variation. Make certain you have the normal value for R14 (1k) on your KSB2 board, and leave R15 at 180 ohms. You will normally use an SSBA setting of 1 with the MH2 microphone. Note that there are really only 2 SSBA settings for the KSB2 - 2 and 3 are the same. There is a mod to increase the KSB2 RF gain, but none to level it out across the bands. 73, Don W3FPR On 3/25/2012 11:09 AM, Jon Perelstein wrote: I've just recently started using phone on my K2/100 (s/n 6550) and I've noticed that even at an SSbA setting of 1, I'm getting a lot of ALC (3-7 bars when I talk in what I believe to be a normal voice). I'm using an Elecraft MH-2 mic. I checked the wiring for the mic last night and I believe it is correct. I also notice that the problem is worse on lower bands than on higher bands. I've been operating the radio at about 80 watts on phone. That's consistent with my experience in digital modes, where I have to turn the output of my computer down to around 20% and keep the TX control of my Signalink turned down to around 2/10ths (the 9 o'clock position). I have checked the jumper settings in my Signalink to make sure I'm not using the special jumper for increased gain on Tx. I operate the radio at 30 watts on digital modes. The KSB2 manual says that the value of R15 can be changed to increase the attenuation on SSbA. What kind of values should I be thinking of? Are there any other adjustments I can/should make to improve the situation? I caught some comment in a post a few years ago about there being an issue with the KSB2 on lower bands and mention of their being a fix, but I'm not sure what to search for in the archives (or rather, the terms I was searching for didn't give me anything that seemed relevant). __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] P3SVGA Question
Yes, I mean 200hz . Actually, the green cursor changes to a dull color barely visible from 150hz to 50 hz. Changing the Span to 10hz will keep this change from taking place and the cursor will stay green from 150hz to 50hz. 10hz is a very narrow Span, but it is the only way I could find to keep the cursor very visible. I have tried everything with the menu on the P3 and also on the monitors, ( I tried two different ones ) I have changed resolution, etc. Nothing seems to change this except changing the Span. It is not a bothersome issue since I would normally only tune the bandwidth down that low after I am in contact with someone, and then the position of the cursor is not an issue. However, I would like the cursor to retain its color and visibility. Toby W4CAK Toby, I assume you mean 200 Hz? At any rate, I can turn mine down to the minimum (50 Hz) and still see the green line. It's fairly dim at that width but still visible. Perhaps you can adjust the color and or contrast on your monitor to bring it out.

Re: [Elecraft] filters and contests and interference question/opinions
Hi Bill, Thanks for the reply. You are correct that I am new to contesting and do the SP method. So yes I try to dial in the frequency and tighten the filters as much as possible. Yes I was getting some AGC pumping and after emails stating this I went and played with my settings on low and high signals and eleminated this problem For running one frequency and trying to create my own pile up has not been sucessful. Michigan is just not that rare I guess :-). However, your point of running your DSP at about 2.0 ish tells me that I might want to keep that filter also incase this ever changes. Or maybe I need to spend more time on one frequency making calls. I have room in the K3 for 1 more filter so I just may go ahead and get a 1.8 to try it out to keep some noise out of the passband when I do the fine tuning. ~73 Don KD8NNU On Sun, Mar 25, 2012 at 9:20 PM, Bill W4ZV wrote: goldtr8 wrote Currently I have a 2.7, and 2.1 filter plus the narrow ones for digital. My brain is starting to tell me to stop using the 2.1 and get either a 1.8 or even a 1.5 or possibly both. My thoughts are that the dsp would work much better if some of the interference can be directly blocked out by the filter. These thoughts are guided by past readings on the list that this is the case. What is the collective wisdom of these filter changes I am thinking about. I am curious about others who may have tried these and if they kept them or if they thought it made no difference at all. The answer is...it depends. :-) I believe you're fairly new to radio and contesting. Therefore I'm assuming you mostly tune for DX stations and call them rather than running a pileup yourself, which requires good antennas and high power on SSB. For DXing or Search and Pounce (SP) contesting, you normally have plenty of time to tune in stations carefully before calling. In this case narrow filters (either XFIL or DSP) will work even with bandwidths down to 1.5 kHz. BUT...this assumes you have time to carefully tune in the station you want to call. In the case of someone running a pileup at fairly high rates (e.g. 150-200 per hour), it's a different situation. You want to copy callers correctly the first time without any tuning, send your exchange and get his exchange in the space of 15 seconds and go on to the next one. The problem with extremely narrow SSB filters is that many callers will be slightly off frequency (e.g. 100 Hz) which renders them unintelligible when using narrow filters. With a little wider filter, your ears can still copy the off-frequency guys without needing to touch the VFO. I had a 1.8k filter in the CQ WW last October and gave up using it because of this problem...and a 1.5k would be even worse. Instead I found myself using a DSP setting of 2.0-2.1k with the stock 2.7k XFIL, so after the contest I traded my 1.8k XFIL for a 2.1k. Unfortunately conditions on my favorite SSB band (10m) have been so poor that I opted not to enter the ARRL DX SSB or CQ WPX SSB and really haven't had a chance to try it under fire, but I believe it will be better than the 1.8k for my purposes. As Don said earlier, the major advantage of a narrow XFIL is to prevent AGC pumping from strong stations nearby. In extremely crowded contests this can be a major problem. However a narrower filter WILL NOT remove the splatter from nearby stations...nothing can do that short of using phased antennas to null their signal. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/filters-and-contests-and-interference-question-opinions-tp7403392p7404470.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

P3 version 1.13 is now available from the Elecraft website and FTP via P3 utility. Release notes for this revision: Removed 57,600 and 115,200 baud from the RS-232 menu. Added SVGA font menu selection to change font size on external display. (Requires upcoming new release of P3SVGA firmware) Added SVGA bias menu selection to adjust waterfall color bias on external display. (Requires upcoming new release of P3SVGA firmware) Monochrome waterfall option now works on external SVGA display also.

Re: [Elecraft] K3 Purchase - Info
I recommend the KXV3A transverter interface. Although you may not plan to use transverters, it also includes the receive antenna input and output feature. Since you are getting the general coverage BPF and 6 kHz filter, I presume you intend to use it also for SWLing, and you might want to use a receive-only antenna. It also makes it easy to insert a noise canceler like the MFJ without worrying about t/r switching. On 3/26/2012 9:44 AM, Dave (K7DRT) wrote: This is my first post.

Re: [Elecraft] KX3 Grounding w/dipole
On 3/26/2012 10:19 AM, Reed Bumgarner wrote: Page 9 of the manual seems to say that creating a ground for the KX3 is necessary in all cases. Is this really true when you're using a Buddipole, Yo-Yo dipole or any dipole fed with coax? This has nothing to do with the radio, but rather comes down to a matter of antenna fundamentals. First, any antenna needs an earth ground for lightning safety. Second, to function effectively as an antenna, any single-ended antenna that looks like a long wire needs some sort of counterpoise to carry the return current (and serve as a return for the electric and magnetic fields). A typical mobile antenna, most verticals, and a wire thrown into a tree all fall into this category. When the rig is tied to ground via the AC power supply and ground rods associated with the shack, that wiring and connection functions as a counterpoise of sorts. When an antenna is mounted on a vehicle and the coax shield bonded to the body, the body acts as a counterpoise. When you use a rubber duck on a VHF or UHF talkie, your body, capacity-coupled via your hand to the talkie, functions as a counterpoise. When operating battery portable with a rig like a KX3, a good practice would be to carry lengths of #22 wire that are a bit shorter than a quarter wave on the frequencies where you plan to operate, and that can be laid out on the ground around you to serve as a counterpoise. K2AV has also written about a folded counterpoise system that you can put together that is more compact than simple wires. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

There's a shelf below it also held away from the wall, that holds power supplies, stubs, and even a few antenna switches, and a shelf above it, also held away from the wall, that holds antenna tuners, a YCCC SO2R box, computer video monitor, rotator controllers, etc. that need some operator interaction.

Re: [Elecraft] Transmitter Alignment
Which parts of the alignment do you wish to do with a scope? I found it useful only for the final alignment of the LC filters in transmit mode because I don't have a sensitive QRP-level wattmeter. I used a modest old scope (Tek 2215) with a 10X probe, a BNC tee, and a good dummy load (Bird TermaLine). The rest of the alignment can be done adequately with just a DMM and the prescribed methods of the K2 manual, but filter alignment and BFO settings can be improved upon by using Spectrogram or any other audio spectrum analysis tool - there are lots of postings on this issue in the forum archives. I ran my K2 very happily for 4 years after using only the K2 manual's procedures for alignment, then re-did them last summer with Spectrogram. I can't claim any dramatic performance improvements except that I could see where the filter passbands were actually located. 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/Transmitter-Alignment-tp7406224p7407085.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Koss Headsets for the K3 (Was: Re: Yamaha CM500
In doing the above mods to the SB40 you end up with a VERY comfortable headset with a great sounding mic element. I just could not get the stock SB40 element to sound good. The HC5 rocks. The alternative is to use one of the Radio Shack electret elements in the SB-40 mic housing. The electret elements are essentially the same as the one in the CM-500 with performance similar to the new HC-6 - broader than the HC 5. With HC-5, HC-6 or an electret element one will still want to use the K3 TS EQ to roll off audio below 200 Hz and add 3 to 6 dB per octave of pre-emphasis above 800 Hz. 73, ...

I replaced the microphone housing on the SB40 with a microphone housing from a broken Heil BM10. Heil still sells the housings and windscreens. In place of the crappy SB40 dynamic mic element I replaced it with a Heil HC5 that a friend had. It's a pity that Heil no longer sells the HC4 and HC5 elements separately.

Probably made in the same Chinese jobber. But here is where the simialarity ends: The Yamaha electrect capsule is flat and can be made to sound really great on the K3. The Koss dynamic capsule is all bass, very mushy, and has low output. Even engaging the K3 equalizers and tweaking a lot, I could not make my SB40 sound very good at all. The capsule just sounds ugly. The fix for this is to remove the two screws that hold the capsule on the SB40's boom and remove the offending microphone that looks surprisingly like a cheap Chinese dynamic earphone (its actually the same exact size as a IPod headset element and looks identical!) and replace it. In my case, I had an old Heil BM-5 with a bad earpiece but a perfectly good DX4 capsule. I removed the plastic mic holder from the rigid Heil boom, and with a slight widening of the boom inlet with a Dremel tool, it fits right on to the SB40 boom! Solder up the existing wires from the Koss mic and you have a wonderfully comfortable headset with a very flexible boom that, in my case, works great on my secondary Kenwood TS570 rig.

I looked at the SB49 first. (The SB45 is identical to the SB49 but without the volume control in the cord). I didn't really like the way the SB49 fit. It's a very subjective thing but comfort was what I was looking for. The other thing I didn't like was the flexible boom for the microphone was very whippy. It was almost like a wet noodle. Not good. Next I looked at the SB40. The fit was great and very comfortable for the 5 minutes I wore it. The mic boom was stiffer too. The SB40 has a dynamic mic element. I ended up buying the SB40. The price was $39.00 plus sales tax. I was all set to buy a Yamaha CM500 but I really wanted to see how they fit first. I looked at a couple places and couldn't find a local store that had the CM500. For this reason I look at Koss. The other thing Koss has going for it is the limited lifetime warranty. Being that I live near the factory this is a big advantage. Second is that I've owned other Koss products and have always been very happy with them. As I said I've never used the Yamaha CM500 but the Koss SB40 looks very similar. I'm also kind of a headphone junkie. With the K3 I figure that most modern headsets have much more performance (frequency response, etc) than one needs for communication.

Needs the latest update installed from Elecraft, parts are included to update. KAT100 - untested, purchased used as in working condition. I have no reason to feel otherwise about the tuner. All manuals are included. I am not interested in separating the above items, would rather sell as a complete package. Worst case problem is possibly replacement of at least one final output transistor in the KPA100. I thought I would go through the exercise of adding the update kit to the KPA100 but just don't have time to do that and have lost the inclination. $950 will puchase all of the above and shipping is included at that price. Paypal add 3% ($28.50) to the total. 73 and best regards for reading my posting.
