[Elecraft] K3 Firmware Updates
Hi All, It has been some time since we had a new release and I am suffering from withdrawal symptoms I think. Has anyone heard about an impending new Beta release anytime soon? I have read all the posts regarding a scope and I am now wondering if Elecraft are designing a plug in unit such as Yucksu did for their FT-2000 FT-950 units. If Elecraft have in mind to do this I really hope they take a real good look at these DMU's and give us something far superior. I was kinda annoyed with mine when I looked at the audio display, I found it pretty meaningless to be honest and of course my FTdx9000D had the same unit and for the price paid I felt a little cheated. If Elecraft decide to do this I have a few ideas of what I would like it to do over and above a bandscope. Anyone got any ideas? K3/100 S/N 679 is just getting better by the day as I figure out what the knobs and buttons do. 73's Gary I just got lost in thought.

[Elecraft] K3: Removing front panel
But DO remember to remove the screw(s) from the 2D connector on lower LHS. Tom G3OLB It would be interesting to me to see somebody prying off the front panel assembly in video form. It's an easy job Brian. Just use a thin screwdriver placed as indicated in the instructions. Go back and forth between the slots on each side, prying it loose a little bit further each time. The connector pins are clearly visible so you can see the progress of the panel coming off. 3-4X on each slot and she's loose. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 #1456 - data modes setup
I tried connecting LINE IN and LINE OUT to the on-board soundcard (Realtek ALC883) on my PC and the problem now appears to be solved. LINE OUT level is now 13 and the MIC (LINE IN) level is now 30, which looks about right. Well, right enough for my first PSK31 contacts with EU stations on 30m. I was running about 5W. I can only assume that the input and output levels on the Aureal Vortex PCI card are too low for the K3. 73 Bob MM0RKT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 #1456 - data modes setup
I need to set the K3 LINE OUT level well above 50 before I can see a trace on MixW's waterfall, even with the soundcard's line in level set to maximum. Bob, some of us have measured distortion on the line out connection on our K3s and find that it is significant on high line-out drive levels. I think the manual suggests nothing higher than 10. Mine has noticeable artifacts on a waterfall with a single tone RF input from an XG2 signal generator with any line-out gain setting above 3. Luckily that is just enough to drive my internal soundcard, YMMV.

Re: [Elecraft] VLF/LF Converters
Geoff: There are a dozen or so experimental stations in the 500 KHz range operated by a group of hams. http://www.500kc.com/ has more detail. It seems that not too many are actually radiating as of this time however. There are also quite a few lowfer Part 15 (unlicensed, but permitted) beacons in the 186 KHz range. The Longwave Club of America is a good starting point for these Part 15 operations. http://www.lwca.org/ No 136 KHz amateur operations here in the US, unfortunately.

Re: [Elecraft] K3 - NR and Rx equalisation
Thanks Stewart--that does make quite a difference.

On cw with a 700Hz offset I find changing the 800Hz

without NR as you'd expect but the difference when the
NR is engaged can be quite remarkable. I can vary this
between seemingly attenuating the received audio
somewhat to increasing it substantially as if an extra
stage of AF amplification has been switched in.
Presumably a few dB extra at the sidetone frequency is
giving the NR more to work on

simple; trial and error I guess.

[Elecraft] Aren't some egg cartons ESD generators???
Greetings: Are not most egg cartons these days made of polystyrene or something similiar? If so, doesn't that material cause ESD?? Seems to me it does. I have avoided the use of that type, thinking that the answers to both questions is yes. Can anyone confirm this? I am certainly no expert on ESD. It also seems to me that even if even if you only store hardware items in them, simply touching the carton or sliding your fingers across that material could generate ESD. Am I overconcerned? I really like using egg cartons for part sorting, but I use the ones made from what looks like a molded grey paper material, which I think is less likely to cause ESD. And to keep them from flipping over, I glue them to a piece of 1/4 plywood, which has a footprint a little larger than the egg carton. You can also write the hardware description on the plywood underneath each cell. I used the molded paper ones when building the K2, the K3, and several other kits with no discernable ESD problem so far. Another question for the experts on this subject: Are the semi ridgid plastic partitioned trays you find in places which sell fishing stuff safe? I have used them, and experienced no problems to my knowledge. 73, George, n4ym ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I didn't put any of the boards in cartons - left them in the bags until needed. Everything else was bonded to earth (via correct leads with 1M ohn resistors), so that is mat, me via wrist strap and the motherboard and then chassis.

[Elecraft] K3- KRX3 and DVR Installation Sequence
I received my KRX3 (ordered with K3/100 #474 on 6/22/07) this past Monday. As we all know, the DVR ordered at the same time is still back ordered. After looking over the KRX3 installation manual I wonder if anyone on the reflector has looked into what will be necessary to install the DVR when it finally arrives. Will there need to be a substantial amount of disassembly of the K3 to get the DVR installed? If this is the case, I will probably hold off on installing my KRX3 until the DVR unit arrives and do it all in one operation. I've not been able to find any documentation on the DVR installation at this point. Perhaps I'm looking in the wrong places.

RE: [Elecraft] K3 #1456 - data modes setup
Bob, some of us have measured distortion on the line out connection on our K3s and find that it is significant on high line-out drive levels. I think the manual suggests nothing higher than 10. The Line Out level is not an absolute voltage - it represents a general gain setting. You will find that the distortion is based on absolute audio signal voltage. As long and Line Out remains below roughly 1V peak (about .8V RMS) distortion levels will be minimal. The specific Line Out setting will depend on your particular AGC settings. If AGC is off, an S9 signal (XG1/XG2, etc.) will generate 1V peak with Line Out as low as 3 or 4. If the AGC is on, the 1V point will depend on threshold and slope. With the highest AGC SLP settings (maximum output flatness), Line Out can be advanced to nearly maximum before the output reaches 1 volt. 73, ...

Just leave them in place and secure them out of the way with an alligator clip to the KPA3 shield. To reinstall, just plug in the 3 cables and drop the KRX3 in. It only takes a couple of minutes. The speed of KRX3 reinstall is a moot point relative to the DVR since as Lyle described, you don't need to remove the KRX3 to install the DVR.

[Elecraft] Egg Cartons and ESD
I used the plastic box method. I like the idea of having a lid that closes when you are not working so maybe you will not spill all those little screws on the carpet or even the desk. I bought mine at Fry's and it was about $7 or 8. Don't put the ESD sensitive stuff in the box or tray. Keep the boards wrapped in the original foam until you are ready to install them. ESD will not hurt the screws, bolts and nuts.

After having it on the bench for most of the last 24 hours and using it in a side by side comparison with my IC-7800, I thought I would pass on my first impressions. I am both amazed and pleased that Elecraft have continued to pack and amazing radio into the size and weight of the package. I find it to perform as well or better than my IC-7800 in many areas. If I had to choose between getting two fully loaded K3s or a 7800, hands down, Elecraft wins. There are however a couple of things I like better about the IC-7800: 1. The spectrum scope and display, with video output. 2. The availability of many features without menus; i.e. lots of knobs and switches. 3. The built in power supply and 200 watts. 4. Rack mountable (19 rack panel) All of those seem tied to the battleship construction and hernia inducing weight of the 7800; of these, the spectrum scope is the most important to me, so I am looking into the LP-Pan as a possible solution. I have a lot more learning to do, to be able to use it more effectively without constantly referring back to the manual, but so far, an amazing radio. I am waiting for the MARS mod software to try it out there, and will start exploring how it does in the sound card digital modes early this week. Well worth the wait; great job Elecraft! I have not figured out if it does this, but I think a worthwhile feature would be to disconnect the antenna automatically on power down (my PW-1 does this) as a small measure of protection. 73 de Dave, W5SV / NNN0SLA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 #1456 - data modes setup
But if you're running PSK31 with a typical wideband filter, the low frequency components (static, noise, other signals) could produce enough distortion to degrade operation of the PSK decoder (in the computer sound card). Operating narrow band modes with wideband receivers is not good engineering practice. If AGC is disabled the receiver and audio (soundcard gains) need to be backed off sufficiently to prevent overload with strong undesired signals. This give up dynamic range on weak signals. If AGC in enabled, strong undesired signals will activate the AGC and reduce gain - often to the point of blocking the weak signal. Narrow receiver filtering makes a big difference and protects the audio circuits from the unnecessary LF energy. As long as the user does not push the IF response below the K3 standard 200 Hz low cut, the LF energy is not a significant issue. A 1V peak tone at 250 Hz has harmonic distortion at -78 dB (2nd), -49 dB (3rd), -81 dB (4th) and -65 dB (5th). The 2nd and 4th harmonics may be lower as the measured values are the noise floor. Although those numbers are slightly worse than at 500 Hz or 1 KHz, -50 dB distortion levels are more than adequate for narrow band reception. By the way, in order to get 1V Line Out levels with an XG2 (preamp on), I found it necessary to disable AGC or set the slope below 10. With AGC and slope settings used by most users, maximum Line Out will not generate a 1V Peak signal for S9 inputs. With AGC, setting Line Out as high as 25 results in maximum audio levels at -15 to -20 dBu which allows sufficient headroom before the onset of distortion. 73, ...

[Elecraft] K3 Beta Firmware, Revision 2.31
K3 beta-test firmware revision 2.31 is now available. This is an extensive update; details appear below. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 2.31 / DSP 1.89, 8-28-08 New Features and Enhancements: * CW SIDETONE INCREMENTS NOW 10 HZ (originally 50 Hz). * RIT CLR switch now works during transmit in all modes and at any time. * RIT CLR MENU ENTRY: You can use this menu entry to select “UNDO ON” or “UNDO OFF”. OFF is the default. When “ON”, tapping CLR will alternate between 0.00 and the present RIT/XIT offset, if any. * DIVERSITY RECEIVE MODE: If you have the sub receiver (KRX3 option) installed, you can take advantage of “diversity receive” by using two separate receiving antennas. This can improve signal copy during fading, and adds a spatial (L/R) effect to signals. DIVERSITY MODE further enhances this capability by slaving the sub receiver’s mode, filter settings, and VFO to the main receiver. To enter diversity mode, hold SUB until you see “DIVRSTY” on VFO B (about 2 seconds). The kHz decimal point of the VFO A display will flash slowly as a reminder that diversity mode is in effect. Notes on Diversity Mode: 1. Entering diversity mode switches the sub receiver to its AUX antenna source. If you don’t hear any right-channel audio, you probably don’t have an antenna connected to the sub’s AUX input. Refer to the owner’s manual or KRX3 manual for information on sub receiver AUX antenna configuration. 2. If your main and sub receiver have 5-pole crystal filters with differing frequency offsets, you may hear a slow phase modulation in the received audio at some VFO frequencies. The only way to eliminate this effect is to use 5-pole filters with matched offsets (available on request; contact Elecraft) or use 8-pole filters, which have no offset. Miscellaneous changes: * DUAL PB CW MIN CONTEXT BANDWIDTH NOW 400 Hz. In high-QRM situations, a 400 Hz or 500 Hz crystal filter may be very useful as a limit to the context bandwidth. Note that the “pedestal” effect (-24 dB context filter) becomes more of a sloped response as the context bandwidth is reduced. * DATA TX ALC IMPROVEMENTS. PWR control is now more responsive during transmit in all DATA modes. * FM SQUELCH THRESHOLD: Closely matched between main and sub receivers. * NOISE BLANKER ON/OFF ON BAND CHANGE: The DSP noise blanker wasn’t set up properly during band changes. It may have been left ON on the new band in some cases. * PA TEMP and FP TEMP are now normal VFO B alternate display modes, meaning that you don’t have to set TECH MD to ON in the config menu. * DDS frequency shifting during T/R changed to eliminate a variation in CW keying duty cycle that was occurring only over specific, narrow frequency ranges on each band. This also eliminated a related CW keying artifact. For software developers: * RG$ command implemented (sub receiver RF gain). * FA, UP ,DN, “RC”, “RU”, and “RD” COMMANDS UPDATE VFO B IF VFOS ARE LINKED (except in SPLIT). These commands can also be used in transmit mode. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] VLF/LF Converters
Regarding the VLF converters, one question I have for the SW folks at Elecraft is whether they could add a transverter band to support these unique receive converter IF frequencies. For example, I have a VLF converter that I've used for years that was designed for a 4 MHz IF. I realize that I can simply tune 4 to 4.5 MHz and mentally ignore the 4 MHz portion of the display, but it would be ideal if I could define a new transverter band where 4 to 4.5 MHz is displayed on the front panel as 0-500 kHz.

RE: [Elecraft] VLF/LF Converters
I have worked the ham station call for the past two years during the Night of Nights and also monitored KPH on all marine frequencies except the 600 meter frequencies. I simply don't have an antenna for anything that low. After the second year I sent a QSL and, as you mentioned, I received a nice QSL on an RCA message form from Ms. Stoops. The volunteers there are doing a wonderful job in preserving an important part of radio history by restoring the old equipment and keeping the station available for tours, etc. I also understand they secured a new coastal station license for KSM which uses the same equipment as KPH and can accept commercial traffic when it is in operation. Monitoring KPH, KFS and WCC helped me with learning Morse back in the days when I was thinking of getting a ham license. I understand WCC was dismantled except for the receive building which they are trying to preserve as a museum but the transmitter location was dismantled and the receive location has no equipment. Fortunately, KPH has not suffered that fate. I wish I lived close enough to the station to visit during the next Night of Nights.

Re: [Elecraft] K3 Beta Firmware, Revision 2.31
Yes, very good. We've had ESSB Diversity implemented. VFO IND next ? 73 Stewart G3RXQ On Thu, 28 Aug 2008 10:42:15 -0700, wayne burdick wrote: K3 beta-test firmware revision 2.31 is now available. This is an extensive update; details appear below. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 2.31 / DSP 1.89, 8-28-08 New Features and Enhancements: * CW SIDETONE INCREMENTS NOW 10 HZ (originally 50 Hz). * RIT CLR switch now works during transmit in all modes and at any time. * RIT CLR MENU ENTRY: You can use this menu entry to select UNDO ON or UNDO OFF. OFF is the default. When ON, tapping CLR will alternate between 0.00 and the present RIT/XIT offset, if any. * DIVERSITY RECEIVE MODE: If you have the sub receiver (KRX3 option) installed, you can take advantage of diversity receive by using two separate receiving antennas. This can improve signal copy during fading, and adds a spatial (L/R) effect to signals. DIVERSITY MODE further enhances this capability by slaving the sub receiver's mode, filter settings, and VFO to the main receiver. To enter diversity mode, hold SUB until you see DIVRSTY on VFO B (about 2 seconds). The kHz decimal point of the VFO A display will flash slowly as a reminder that diversity mode is in effect. Notes on Diversity Mode: 1. Entering diversity mode switches the sub receiver to its AUX antenna source. If you don't hear any right-channel audio, you probably don't have an antenna connected to the sub's AUX input. Refer to the owner's manual or KRX3 manual for information on sub receiver AUX antenna configuration. 2. If your main and sub receiver have 5-pole crystal filters with differing frequency offsets, you may hear a slow phase modulation in the received audio at some VFO frequencies. The only way to eliminate this effect is to use 5-pole filters with matched offsets (available on request; contact Elecraft) or use 8-pole filters, which have no offset. Miscellaneous changes: * DUAL PB CW MIN CONTEXT BANDWIDTH NOW 400 Hz. In high-QRM situations, a 400 Hz or 500 Hz crystal filter may be very useful as a limit to the context bandwidth. Note that the pedestal effect (-24 dB context filter) becomes more of a sloped response as the context bandwidth is reduced. * DATA TX ALC IMPROVEMENTS. PWR control is now more responsive during transmit in all DATA modes. * FM SQUELCH THRESHOLD: Closely matched between main and sub receivers. * NOISE BLANKER ON/OFF ON BAND CHANGE: The DSP noise blanker wasn't set up properly during band changes. It may have been left ON on the new band in some cases. * PA TEMP and FP TEMP are now normal VFO B alternate display modes, meaning that you don't have to set TECH MD to ON in the config menu. * DDS frequency shifting during T/R changed to eliminate a variation in CW keying duty cycle that was occurring only over specific, narrow frequency ranges on each band. This also eliminated a related CW keying artifact. For software developers: * RG$ command implemented (sub receiver RF gain). * FA, UP ,DN, RC, RU, and RD COMMANDS UPDATE VFO B IF VFOS ARE LINKED (except in SPLIT). These commands can also be used in transmit mode. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] VLF/LF Converters
Scott, Right now, the K3 XVx RF can be set to most any frequency (MHz increment) from 0 to 999 - but unfortunately the IF frequency is currently limited to 7, 14, 21, 28, and 50 MHz. If we could convince Wayne and Eric to support the 10 MHz band as an IF, that would work for the 10 MHz IF used in the Jackson Harbor Press kit that has received some recent 'press' here. I suppose a 4 MHz If might be possible too - but that may depend on how many users there may be. What is the chance that you could change the mixer crystal to give your VLF converter a 7 MHz IF? If it has tuned circuits at the output, those would have to be changed to the new IF as well, but it certainly should not be a daunting task, perhaps just a few toroids to wind. I don't know how well any of this works because I have not tried it, but it seems feasible looking at the K3 transverter interface menus. 73, Don W3FPR Scott Prather wrote: Regarding the VLF converters, one question I have for the SW folks at Elecraft is whether they could add a transverter band to support these unique receive converter IF frequencies. For example, I have a VLF converter that I've used for years that was designed for a 4 MHz IF. I realize that I can simply tune 4 to 4.5 MHz and mentally ignore the 4 MHz portion of the display, but it would be ideal if I could define a new transverter band where 4 to 4.5 MHz is displayed on the front panel as 0-500 kHz.

RE: [Elecraft] W8JI review on eHam
I personally know Tom. He used to live within 15 miles from me before he moved to Georgia. He is an extremely knowledge person. I have NEVER known Tom to flat out rave about any radio equipment. I think his review of the K3 really means something because he always tells it like it is. The K3 is relatively small and rather innocuous looking. But in this case appearances are very deceptive. If your main interest is a large box with lots of flashing lights, maybe the K3 is not for you. I have some of those large boxes in the shack. But if you want superior performance and a company which is truly interested in making it the very best it can be, the K3 is for you. As Tom said, the K3 is amazing. If I worked for some of the other companies, I would be afraid . . . very afraid. I don't know how Elecraft can do all this with only 24 people but I suspect that may be part of the reason why it is amazing. The owners are very close to their customers.

(I almost hate to write this review. I'd like to be the only person in the world with a K3.) I like raw performance. I like working weak DX stations on low bands. I like contests. Because I have guest ops that aren't always accustomed to the radios I have, the radio has to be easy to use. With contacts coming three or four a minute for hours on end, with over a dozen antennas to pick, the radio can't be difficult to use or distracting. It also has to be top notch. This is a demanding situation with large antennas in a very quiet location. The location and large antennas demand uncompromised receiver and transmitter performance. Some top-of-the-line radios selling for three times the price of the K3 only lasted a few days here. Some have had serious design problems like so-called diversity that does not actually phase lock. Some only offer a crummy sub-receiver that isn't even worthy of being called second rate. By sub they must mean sub-standard. Some have transmitter keying issues or unreasonable transmitter IM on SSB, many have receiver close-spaced strong signal handling issues. I purchased one brand new top-of-the-line high-dollar radio, assured by the sales people it was the best radio ever, and the thing was not as good as my 15 year old FT-1000D in several different ways. I thought I was destined to spend my life going back to the FT1000 and heavily modified solid state mixer and IF section diversity R4C's. Enter the K3. I measured around -35 to -38 dB SSB transmitter IM3, better than my other radios. The transmitter is flawlessly clean on CW also. The raw receiver performance on HF is second to none. It is significantly better than radios costing three times as much as a loaded K3. The K3 is an incredibly easy to use radio, and it is very simple to upgrade firmware. Just a couple mouse clicks and the new firmware is located on their website and loaded into the radio. Elecraft is also super fast in updating and improving firmware, their response to suggestions is like nothing I have ever experienced. I didn't like the way a few controls functioned in diversity mode. The knobs required a little more operator attention than I liked. Unlike other companies, when I e-mailed Elecraft they listened and agreed. Within a week a firmware upgrade corrected the difficulties. Now it is smooth as silk. Can you imagine any other radio manufacturer in the world responding like that? It's unheard of today! I'm going to make a prediction. Within a few years all the successful serious contesting stations and DX chasers will have K3's. This is the first time I've bought a radio and not been disappointed. As a matter of fact, I'm ecstatic about the K3 performance and Elecraft's service. I've waited almost 20 years for the next major improvement in radios, and this is it. Not only is the radio great, the service and support exceeds all reasonable expectations. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] VLF/LF Converters
Don: It's certainly possible to change my VLF converter such that a 7 MHz IF is used instead, but I brought this up primarily because the addition of these virtual bands shouldn't be a tremendous effort in SW. But, of course, such things are always simple for the person who doesn't have to actually do the work. And the inclusion of such a band could open up the floodgates for special band requests. To standardize things a bit, I recommend that Elecraft consider adding the 10 MHz band as an IF in the transverter menu. I can easily move my VLF converter to a 10 MHz IF and the LO can be supplied by my local H/P frequency standard.

[Elecraft] Beta 2.31/DSP 1.89 CW Increments vs. DSP shift increments
Thanks to Elecraft for the 10 Hz CW pitch increments. I'm a little confused though, since the shift increments are still 50 Hz. For example, when I set the pitch to 380 Hz, the asterisked shift frequency is 0.35 Khz. When I set the pitch to 340 Hz, the asterisked shift frequency is 0.30 KHz. It seems to me there is a problem with rounding here. 73, Chuck NI0C K3 s/n 1061 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 SSB on 40M
Can't get proper output on 40M SSB. Rig works fine on all other bands. On 40M gives full output on CW but when switched to SSB although the Comp and ALC readings are OK (i.e.as for all other bands) but there is very little RF output.

[Elecraft] K3 Beta Firmware, Revision 2.31 E 00000C ERR DSE
Hi all, I just upgraded to the latest beta. Set pitch to 630 and then varied the WIDTH and SHIFT. Set the WIDTH for 0.80 then when shifting passed FC 0.35, the receiver dies with an error E 0C ERR DSE. It doesn't appear to matter what the pitch tone is set. After the error occurs, you must change the SHIFT setting 0.35 and power off and on.

He is an extremely knowledge person. I have NEVER known Tom to flat out rave about any radio equipment. I think his review of the K3 really means something because he always tells it like it is. The K3 is relatively small and rather innocuous looking. But in this case appearances are very deceptive. If your main interest is a large box with lots of flashing lights, maybe the K3 is not for you. I have some of those large boxes in the shack. But if you want superior performance and a company which is truly interested in making it the very best it can be, the K3 is for you. As Tom said, the K3 is amazing. If I worked for some of the other companies, I would be afraid . . . very afraid. I don't know how Elecraft can do all this with only 24 people but I suspect that may be part of the reason why it is amazing. The owners are very close to their customers. Bruce - W8FU -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Tippett Sent: Tuesday, August 26, 2008 11:12 AM To: elecraft@mailman.qth.net Subject: [Elecraft] W8JI review on eHam http://www.eham.net/reviews/detail/6673 Elecraft is amazing! (I almost hate to write this review. I'd like to be the only person in the world with a K3.) I like raw performance. I like working weak DX stations on low bands. I like contests. Because I have guest ops that aren't always accustomed to the radios I have, the radio has to be easy to use. With contacts coming three or four a minute for hours on end, with over a dozen antennas to pick, the radio can't be difficult to use or distracting. It also has to be top notch. This is a demanding situation with large antennas in a very quiet location. The location and large antennas demand uncompromised receiver and transmitter performance. Some top-of-the-line radios selling for three times the price of the K3 only lasted a few days here. Some have had serious design problems like so-called diversity that does not actually phase lock. Some only offer a crummy sub-receiver that isn't even worthy of being called second rate. By sub they must mean sub-standard. Some have transmitter keying issues or unreasonable transmitter IM on SSB, many have receiver close-spaced strong signal handling issues. I purchased one brand new top-of-the-line high-dollar radio, assured by the sales people it was the best radio ever, and the thing was not as good as my 15 year old FT-1000D in several different ways. I thought I was destined to spend my life going back to the FT1000 and heavily modified solid state mixer and IF section diversity R4C's. Enter the K3. I measured around -35 to -38 dB SSB transmitter IM3, better than my other radios. The transmitter is flawlessly clean on CW also. The raw receiver performance on HF is second to none. It is significantly better than radios costing three times as much as a loaded K3. The K3 is an incredibly easy to use radio, and it is very simple to upgrade firmware. Just a couple mouse clicks and the new firmware is located on their website and loaded into the radio. Elecraft is also super fast in updating and improving firmware, their response to suggestions is like nothing I have ever experienced. I didn't like the way a few controls functioned in diversity mode. The knobs required a little more operator attention than I liked. Unlike other companies, when I e-mailed Elecraft they listened and agreed. Within a week a firmware upgrade corrected the difficulties. Now it is smooth as silk. Can you imagine any other radio manufacturer in the world responding like that? It's unheard of today! I'm going to make a prediction. Within a few years all the successful serious contesting stations and DX chasers will have K3's. This is the first time I've bought a radio and not been disappointed. As a matter of fact, I'm ecstatic about the K3 performance and Elecraft's service. I've waited almost 20 years for the next major improvement in radios, and this is it. Not only is the radio great, the service and support exceeds all reasonable expectations. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] New K2 now!
Ditto what Bruce said. I purchased my K2 to get the radio that fit my needs. I did not focus on the building. But it turned out to be much more fun than expected. The directions are very straight forward. Do your inventories, and just start working your way through the parts. Before you know it, the front panel and control board will be together. Then you start on he RF board. The majority of it is just putting the right part in the right place, and soldering it well. Once you start doing some checks, you will really feel a sense of accomplishment. A great radio, and you learn something too. Both about the equipment and yourself. It doesn't get much better than that.

RE: [Elecraft] VLF/LF Converters
Actually 4 MHz is probably the most common I.F. for LF/MF converters. Many Ham band rigs receive in the 4.0 to 4.5 MHz range and it uses a commonly-available and cheap 4.0 MHz crystal for the L.O. The other designs I've seen mostly use that range. I bread boarded a diode ring mixer converter for the 400-500 kHz range, but haven't converted it into a finished unit yet so I haven't investigated what the K3 (or the K2) will with it in the transverter menus. Ron AC7AC -Original Message- Scott, Right now, the K3 XVx RF can be set to most any frequency (MHz increment) from 0 to 999 - but unfortunately the IF frequency is currently limited to 7, 14, 21, 28, and 50 MHz. If we could convince Wayne and Eric to support the 10 MHz band as an IF, that would work for the 10 MHz IF used in the Jackson Harbor Press kit that has received some recent 'press' here. I suppose a 4 MHz If might be possible too - but that may depend on how many users there may be. What is the chance that you could change the mixer crystal to give your VLF converter a 7 MHz IF? If it has tuned circuits at the output, those would have to be changed to the new IF as well, but it certainly should not be a daunting task, perhaps just a few toroids to wind. I don't know how well any of this works because I have not tried it, but it seems feasible looking at the K3 transverter interface menus. 73, Don W3FPR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] VLF/LF Converters
Or better pre-selection, such as a high-Q tuned antenna. I don't mean a typical active antenna either. Most of them are a broadband amplifier hooked to a whip. Signals way off frequency are amplified right along with the desired ones and no amount of preselection after the antenna is going to help once the amplifier at the whip has generated broadband cross mod. When I lived near Portland I had that problem on any MF receiver I tried, so I built a small ATU for that range and hooked on my HF antenna as a random wire. With the tuner in the circuit the MF range went from noise caused by BCB and every other sort of monster signal overloading the RX to Q5 copy of a large range of non-directional beacons (NDBs) and stations like KPH. Those NDBs only run 50 watts or so into a short antenna, yet I copied many of them over a range nearly 1,000 miles when cdx were good. All that aside, the fate of the 600 meter band seems sealed because the US Coast Guard (USCG) has reserved virtually the whole 400-500 kHz spectrum for low-frequency GPS beacons. Those beacons will transmit correction signals that improve the accuracy of GPS sufficient to control vehicles on the ground and to land aircraft. (It's no surprise that almost all of those beacons are slated for installation at airports.) I'm a little surprised that the FCC has issued some 600 meter licenses to coastal stations since, but those may be subject to cancellation at any time the USCG wants, just as the Amateur experimental license is provisional. So, one of these days, the 400-500 kHz band will be wall-to-wall data beacons bleating out their information to GPS receivers nearby, and in the slot just above 500 kHz and below the AM broadcast band we still have NAVTEXT broadcasting text weather reports to ships. I don't know the fate of the LORAN system there. It's been heralded as a backup to satellites, and there's some good sense in doing that. It all depends upon Coast Guard priorities with their greatly-expanded Homeland Security mission since 9/11. Ron AC7AC -Original Message- I'm on the west coast [near Sacramento] and about 120 miles from the XRAY-9940 LORAN-C station at Middletown CA, and about 190 miles from the Master-9940 at Fallon NV. Both run 400KW peak [I think]. That's about all I can hear anywhere from below 100 KHz to 400 KHz or so with my Palomar VLF converter, the signals are huge. Maybe I need a different VLF box. 73, Fred K6DGW ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K3 SSB on 40M
This sounds like exactly the same problem I had. Upgrading from 2.22 to 2.23 solved the problem. Worked fine on cw, and on USB bands but on 40/80 LSB no HP output and next to nothing on LP. I should note that after upgrading the LSB HP problem was fixed but an ATU problem appeared. Redoing the 5 and 50 watt calibration and then the TXMTR GAIN calibration on all bands got the rig to %100 functionality. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of WA6L Sent: Thursday, August 28, 2008 3:32 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 SSB on 40M Jack, AE6GC It has been in Aptos for two weeks now. :-( We will see . . .

Re: [Elecraft] K3 SSB on 40M
It occurrs on all bands when ESSB is turned on but the sideband varies. On 40 it's really obvious because low output happens in LSB. On 15m it's not obvious because it happens in USB. Elecraft just told me to install the new firmware which I had already done and to do an alignment via the menu. I'll fiddle with it later but I still think something is fishy.

[Elecraft] Portable QRP with a KX1
Over the past two weeks my wife and I have done quite a bit of travelling - Columbus, OH to visit our daughter, Wheaton, IL to visit my mother, and Ludington, MI for a few days of personal RR. I took along my shack-in-a-box which consists of an Elecraft KX1, a pack of 10 NiMH AA batteries, a Palm paddle, and a 40-ft random-wire antenna with three 16-foot radials all made from very thin bead wire. In each location I managed to find a few minutes to slip out to the backyard or to a nearby park, shoot the antenna up into a convenient tree (slingshot), and enjoy a few QSOs with a mighty three watts of power. Most of my contacts were made on 20 and 40 meters, with one or two on 30. I worked KS, FL, PA, VT, MO, VA, CT, WA, NJ, and OH, along with a couple of DX - an EA6, and an EA7.

[Elecraft] K2 K3: PowerMate Knob Utility
Hello! If you are interested in testing and providing feedback on pre-release software, you have a Griffin Technology PowerMate knob, and a PC running Windows XP connected to your K2 / K3 serial port, then read on. I do not have a K2, and thus support is limited, but I would be interested in hearing from any K2 testers. Responding to requests to provide a K2/K3-specific driver and utility to permit use of the Powermate, I developed a Windows application, EZSet3, that allows the user to program K2/K3 commands into the PowerMate knob's TAP, HOLD, ROTATE CCW, ROTATE CW movements. EZSet3 is released under a 'no fee' GNU GPL license. The application features an practically unlimited storage for the user's favorite commands, 10 knob function program access buttons and operation in the background so other programs can run. In fact, simultaneous operation of the PowerMate with a panadaptor, logging program, Elecraft KRC2 and SteppIR has been tested. Here is the Griffin site if you are curious about the PowerMate: http://www.griffintechnology.com/products/powermate EZSet3 application installation files can be downloaded here: http://www.mclendon.info/files/SetupEZSet3.zip I have no affiliation with Elecraft or Griffin other than that of customer.

[Elecraft] K3 ESSB/SSB firmware corrected; Beta revision now 2.32
Well, this is why we do beta test Revision 2.32, now on our web site, corrects a major problem we introduced in rev 2.31 and somehow didn't catch during our own testing. ESSB should once again be functional, and LSB/USB balance in both normal SSB and ESSB should be improved. Also note that we're planning to further improve the ESSB passband in future revisions. At present when you select 4.0 kHz, for example, you might get a -3 dB cutoff of around 3700 Hz. While this is much wider than normal SSB, we think we can extend it. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Ron wrote: Or better pre-selection, such as a high-Q tuned antenna. Or get something like the US Navy's R-1134/WRR-3, which was on several ships that I served on 30 years ago. It is mechanically digital tuned, all vacuum tube, and covers VLF to MF (14 to 600 kHz). It's a real link to maritime MF Morse operations, and only weighs about 60 lb! It's really the last of a breed. When I lived near Portland I had that problem on any MF receiver I tried Remember how often MF maritime Morse signals were heard coming in on the IF or as images on common AM broadcast band receivers. I used a WWII surplus BC-453-B to properly copy maritime Morse from 420 to 520 kHz in the 1960s. It did a pretty good job of it. Even in the 1980s I listened at night to 500 kHz on a modern receiver. Never tired of it. I'm a little surprised that the FCC has issued some 600 meter licenses to coastal stations... One hopes that a small region around 500 kHz will remain free, and dedicated to preservation of this extremely historically significant band. Maybe A2 MCW should be authorized to experimental licenses. Differential GPS beacons don't have the same mystique. I never found ham Morse to have the same interest. Maritime Morse MF and HF frequencies were far more interesting. It's hard to believe that less than ten years have passed since commercial radiotelegraph ceased. I received a solicitation in 1991 from a US radio officers union seeking operators. It seems that activation of old US-flag vessels to support the first Irag war led to radio officer shortages. I'd have been tempted if I'd been 15 years younger. I don't think there's much motivation today for ham equipment to have capability for LF/MF coverage.

[Elecraft] [K3] Wide CW RX issue in 2.32 firmware
With 2.32, CW mode doesn't seem to have the correct bandwidth above 1KHz, which is my 2nd-widest filter. LSB mode provides good bandwidth at 2.8Khz, but in CW mode, it doesn't offer that same result at 2.8Khz. I thought perhaps the issue was the center frequency of 600Hz vs 1.5Khz, and perhaps it is, but when I shift the CW center frequency, I don't get any more bandwidth. Furthermore, the audio sounds markedly different when I veer off of 600Hz center by even 50Hz, as if it's selecting a different xtal filter or something. If this isn't as designed and you can't reproduce this please let me know and I'll provide .wav file recordings for you to examine on a spectrum scope. 73 es TNX, Leigh/WA5ZNU K3#51 recent ECOs for HAGC and CW waveshape Well, this is why we do beta test Revision 2.32, now on our web site, corrects a major problem we introduced in rev 2.31 and somehow didn't catch during our own testing.

K1EA CT-DOS V 10.03, set COMTSR2 -b4800 active, choose TS940 as transceiver and in ct setup, comport2 = radio1, 4800baud. Bandmap, band changes-from the K3 from CT all worked. Did not check split freq operations. lpt2 as keying interface with CT paralell port circuit worked fb NOTE: I had no tnc and cannot vouch for point es shoot, announcements etc Using CTWin Windows op version of K1EA CTWIN: PC: Dell laptop 840c, xp pro, with Prolific USB-Comport device as comport3. Baud rate 4800 Transceiver TS940, setup: comport3 = radio1, 4800 baud rate LPT2 as keying input RESULTS: CTWIN worked fb EXCEPT entering freq on ctwin did not change the K3 frequency but changing the freq on the K3 registered fb on ctwin. Again no experience with a tnc, spot annoucements etc. I do not know how to set up CTWIN for TELENET operations. Using ctWIN IN WINDOWS XPPRO, K1EA CTWIN PC: Dell840c laptop, Prolific USB-Comport device AND LP-Bridge software from Telepostinc.com setting LP-Bridge Virtual Comport 1 with 1A option checked K3 baudrate set at 38400 baud. LPT2 as keying input toctwin. RESULTS: CTWin worked fb, could set K3 freq from ctwin, all else as above. This technique of using a Virtual COMPORT via LP-BRidge might be one method of using both the LP-PAN panadapter AND a logging/contest program simultaneously. NOTE there are 3 possible VIRTUAL COMPORTS available on LP-Bridge software. Others might relate their expereinces with other loggin/contest software as well alex w2ox alex w2ox at 38400 and ctwin setup comport1 =radio1, baudrate 38400, tranceiver TS940 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
