[Elecraft] Elecraft Support
I would, once again, like to applaud Gary Surrency at Elecraft K3 Support for his patience and speed of response in helping me install a firmware fix yesterday. The level of technical support provided by Elecraft is superb. 73 Tom G3OLB __ 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

Our electricity bill is high enough as it is, and besides, leaving stuff switched on when it isn't being used is not a very responsible use of non-renewable resources. I'd be happier with a computer-based solution if the software ONLY gave you the panoramic display. I want a standalone display that I can use alongside the software of my choice but although I certainly understand the reasoning of those who want one that will work without a PC I personally don't mind if it is a standalone application. I can always buy a second monitor to display it on if I want to. What I don't want or need is a whole screenful of PowerSDR which was designed to be the front end to a fully computer controlled radio not a "simple" panadapter. - Julian, G4ILO.

[Elecraft] [K3] Newer K3 user
I've was in the dark ages of radio for sometime. Over year ago I decided to update my HF transciever, the newest one I was using was an SB-102 Heathkit. I didn't have money to burn, (not that it would help) I wanted the most modern and new at a good price. Something traditional looking and hopefully a kit. So after a little research, the K3 came up. I had seen the K2 and was considering going down that road until the K3 was released. I waited a while until some. kinks were worked out and ordered one (No.2483). It arrived a few months later (forgot to confirm the email), then it sat for another few months until I could pick it up. The waiting was nuts. I built it over a fews days when time permitted, (about 7-8 hours) did the mods/fixes on the boards too. I couldn't belive how well everything fit together - amazing. Reading this forum and various reviews over the interim was a real help, it made me aware of a few things. It has the lastest firmware (beta version) and I use a Gamma HPS-1a power supply to - modernise. I took it all to the club meeting, hooked it up and dazzled everybody there, like little kids in a candy store. The whole set-up sans antenna fit in a briefcase and weighed nothing. This K3 is more radio than I am ham. After a few months using the K3, I loaded up HRD on my laptop at the urging of a fellow club member to stop using the old paper logs and get a computer logger. That's another story. Neat stuff. So much to learn. So the shack is cooler now, electric bills are lower and I have sooo much more room on my desk! Thank you all at Elecraft for making such a great product. I have a few questions about the some issues with the betaware, but I'll put that in another post. 73, Douglas 4Z5TO -- View this message in context: http://n2.nabble.com/Newer-K3-user-tp3324807p3324807.html Sent from the [K3] 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] New K1 on the way - Band Module Questions
Hi All, I sure agree with Rick's comment. I liked my K1 from the outset, but not nearly as much as I have since I finally got the 4 band board installed! As nicely designed as the K1 is, swapping band boards got to be a real pain. Personally, I would never recommend that someone only buy a 2 band board unless they were absolutely, dead certain they weren't going to want to upgrade later. Of course, initially the 4 band board wasn't available. Some folks may be put off by the fact that 17 isn't the CW band that 40, 30, and 20 can be, but when 17 is good, it's really good! So, if you decision about getting the 4 band board is tempered by uncertainty about 17 meters, I'd suggest you add it to your system. Even while propagation was falling off the face of the earth this past year or so, I worked a lot of good DX on 17 meters. I've also been less than thrilled with the internal battery option in either the K1 or the K2. I think it's better to forgo that option, and just use outboard power sources. That way, you have more flexibility about what size power source you provide, and the rig doesn't get weighed down with batteries. Probably a lot of folks will disagree with that, but it's strictly personal preference. You still have to have "the weight" somewhere, but with external power you can pack it separately, like "checked luggage" vs. "carry-on". The internal ATU option is a tricky decision. I have it in both the K1 and K2, but the T1 is a super alternative. If you have both rigs, or other rigs (like an FT-817 maybe?), the T1 can solve a lot of problems. If I was really pinching pennies (which I seem to be doing more of these days!), I might have just let the T1 be my sole tuner option for QRP stuff. If you have any kind of collection of QRP rigs, you will probably want the T1 anyway. It's a great little tuner. Dave W7AQK - Original Message - From: "Rick Dettinger" To: "Gary W.

I have nothing against the T1, but another low cost ($65 kit, $90 assembled) alternative is the Emtech ZM-2: http://emtech.steadynet.com/zm2.shtml It's small, light (8 ounces), passive (non-autotune but very easy to tune and no battery to worry about) and tunes virtually anything on 10-80m (but not 160).

The 8-pole filters do have significantly better shape factor but mostly at the lowest levels on the filter skirts. For the most part you will never see the difference as the DSP has an almost rectangular response. You're not likely to see any real difference between the 500 Hz 5-pole and 400 Hz 8-pole filters in practice. I've measured the -6dB bandwidth of the 500 Hz 5-pole filters in both of my radios at just under 500 Hz and the -30 dB bandwidth at about 760 Hz. This compares to the published data of 435 Hz @ -6dB and 650 Hz @ -30 dB for the 400 Hz 8-pole filters - see: www.elecraft.com/K3/K3_8_pole_plots.htm or www.inrad.net/product.php?productid=150&cat=140&page=1 73, ...

Re: [Elecraft] K3 160M Diversity Users
Hi Gary, Do keep in mind that in CW mode, the maximum audio bandwidth is limited by the DSP to 2.8 kHz even if you have the AM or FM roofing filter installed. Even in phone modes, the audio rolls off somewhere around 4 kHz, so that would give you a fairly narrow chunk of the band at audio. 73 -- Joe KB8AP On Jul 24, 2009, at 10:43 PM, Gary Hinson wrote: ... > > I'm thinking of getting the AM and/or FM filters next so I can open up > the bandwidth to listen to a whole chunk of band at once using an AF > spectrum program: it sometimes helps to listen to all the callers in a > pileup and to choose a clear slot to call. > > 73, > Gary ZL2iFB __ 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] K3 160M Diversity Users
My experience pretty-much aligns with Bill's. I started out with matched pairs of 5-pole 500 Hz and 5-pole 200 Hz filters. The 500/200 combination makes a little more sense than the 400/250 combination because there's more difference between the filter widths. Like Bill, I rarely use the 200 Hz filters. Most of my use is contesting. If you spend too much time with BW cranked down to 200 Hz or less, you're going to miss a lot of callers. I only use narrow BW when someone plops down very close to my frequency when I'm in the middle of a QSO. That said, the narrow BW saves me every now and then, which for me is worth the cost. I was fairly satisfied with the 5-pole 500 Hz filters, but was sometimes bothered by thumping and clicking from loud stations (S9 and higher) just above my passband. This is likely caused by the hardware AGC activating at somewhat too low a level. Quite a while ago there was a fix to the RF board to raise the threshold, but some of us think it's still too low. At any rate, though the theory says that roofing filters aren't responsible for the ultimate selectivity (the DSP does that), I found that they do make a difference in the above situation. Switching off the 500 Hz filters and using the 200 Hz filters produced audibly less interference, most likely by providing greater attenuation at the hardware AGC stage. That induced me to replace the 5-pole 500 Hz filters with 8-pole 400 Hz filters. The result was a minimal improvement, not easily detected by testing. The real test will come this fall when I'm squeezed into 40m or 20m with zillions of loud stations on either side. All that said, Bill is correct that, with the matching fee, the price difference between 5-pole and 8-pole filters is small enough that it makes sense to get the 8-pole filters. I should note that the 8-pole filters are not necessarily perfectly centered, but they're close enough that you probably won't need to use any offset for diversity. As far as the 200 Hz vs 250 Hz filters go, if you want to have them in reserve for those really tough QRM situations, I would get the 5-pole 200 Hz filters. Elecraft says they're narrower than the 250 Hz filters all the way down. Also, there's more BW difference between the 200s and the 400s/500s. I agree completely with Bill on the merits of diversity: with the right antennas, it's amazing. 73, Dick WC1M > -Original Message- > From: Bill W4ZV [mailto:btipp...@alum.mit.edu] > Sent: Friday, July 24, 2009 10:27 PM > To: elecraft@mailman.qth.net > Subject: Re: [Elecraft] K3 160M Diversity Users > > > W4UM wrote: > > > What are your recommendation if I were to get only > one pair of filters? > > I would go with either the 500 or 400 8-poles. > > > Is there any real value to getting a pair of narrow > (200Hz or 250Hz) filters as well as a pair of the wider (400Hz or 500Hz) CW > filters, or am I just wasting money? > > I have a 200 Hz in my Main in addition to 500 Hz 8-poles in Main and Sub. > If you contest or are in huge simplex pileups, there are definitely times > when the 200 Hz may be useful.

I would find a "hybrid" solution more useful, ie. stand-alone or capable of interfacing w/ a PC. The current problem I run into now is that there is no "practical" way to run two LP-PANs (specifically PowerSDR) on one PC, one for each of two K3s. I've tested doing so w/ one instance of PowerSDR in a VMware container, but additional bandwidth limitations (virtual sound device), delays, et.al. are less than optimum. With two stand-alone units, there wouldn't be a particular PC-related limitation, but then "point-and-click" may be lost. Though, as I understand it, there were plans to use a "tuning" knob on the front panel with push capability to jump to K3 to the freq. were the on-screen marker is located. The Elecraft panadapter could take a couple directions as far as PC integration. 1) Provide I/Q outputs to interface w/ the PC's soundcard, or 2) Have a built-in USB sound device (ie. similar to some Microham devices). The latter would certainly increase costs, but would eliminate the need to go out and purchase a high-end card; maybe include it as an add-on option in the same style as everything else in the K3 realm. Anyways, it will be interesting to see the product when it arrives.

[Elecraft] Kits built for W4PM
I received 9 responses with offers to build the K2 and/or the KX1. In addition I received 3 or 4 other responses directing me to builders. I appreciate all responses. I need to put all the information into a spreadsheet (I'm a former accountant) so I can quickly compare the various responses. Some quoted prices, others needed more information. Here's more information: KX1 -Includes the 30M adapter. This kit has not been started. The box has been opened but all parts are in original parts bags and/or wrappings. The owners manual is REV A 10/10/03. The serial number may be 000100 if that's what that number on the box is? K2 - a very early kit which includes the following manuals: Rev A - 06/14/99 REV C - 04/19/00 The original owner must have ordered the newer ones later! REV E - 02/16/03 The original owner sorted and checked all parts and has them in boxes in envelopes identifying the contents of each. A set of prewound coils is in there too. There is also a box identified as "Revision B Components kit". In this kit components are all in original bags or wrappings. It has a new serial number of 03309. The original owner included a literal "mountain" of printed messages from the various Elcraft reflectors. The actual building of the kit has not been started. No soldering gun, wire cutters, screw drivers etc have ever approached this kit! :-) Frankly with all the various changes that have occurred I would not know where to start. Again thanks for the interest shown in this project. For those who needed more information before quoting a price let me know if what I provided above is sufficient. Those who inquired if I had received their messages, be assured I did but the response has been a bit overwhelming. For now I'm posting this to the reflector rather than respond to each of you individually. 73, Puck, W4PM __ 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] [K3] : Installing KBPF3 in the sub-receiver
Hi Elecrafters, I'm planning to perform most of the available enhancements on my K3/100 (#0615) with the objective of removing only once the KRX3 module. The question I have : is it possible to install a KBPF3 module in the subreceiver without removing the KRX3 module (provided, of course, that the two KBPF3 1/2" standoffs are already mounted on the KRX3 board). In the KBPF3 installation manual (Revision D - June 24, 2008), it is clearly stated page 7 that "If your K3 is equipped with the optional KRX3 subreceiver, you must remove the subreceiver module to install the KBPF3 in either the main receiver or the subreceiver." Nevertheless, when I read the KRX3 assembly manual, I have the feeling that it should be possible to install the KBPF3 module in the subreceiver without removing the KRX3 module. Could somebody clarify this issue ? Thanks and 73, de Raymond, F4FNT. __ 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] [K3] dBV display
I don't use the dBV display very often, but since I last did many firmware updates ago it seems to have developed a problem. Very often, the reading is stuck on +99.9dBV. Sometimes, rotating the VFO B knob to select a different reading, then back to dBV, gets it working. I'm in data mode with the AGC off, though I'm not sure that is always the case when this happens. Can anyone reproduce this? Perhaps it just needs a squirt of virtual WD40. - Julian, G4ILO.

Re: [Elecraft] [K3] dBV display
Hello Julian! > I don't use the dBV display very often... First, you need to select AFV. Once that is stable, go to dBV and you will then read dB relative to the AFV level. If you go directly to dBV, it is referenced to 0 so you get an over range.

I must have been going to AFV accidentally, which was getting it going. The problem must occur when it is left in the dBV setting from the previous time the radio was used. I didn't know you had to do that. It always seemed to just work before. Thanks for the info! - Julian, G4ILO.

Re: [Elecraft] [K3] dBV display
Julian, You moved too quickly through the AFV display. The way dBV works - it provides the delta from the last stable AFV value. Go to AFV and wait until the value settles down, then move to dBV and you should see a value very close to zero if the audio is close to what it was when you were on AFV. Now rotate your antenna, or change antennas, or or switch between whatever you are comparing, and you should see the variation in dB. To be meaningful, dBV should be used with a steady signal source (unless you want to indicated the varaition between two signals). 73, Don W3FPR Julian, G4ILO wrote: > I don't use the dBV display very often, but since I last did many firmware > updates ago it seems to have developed a problem.

Re: [Elecraft] Kits built for W4PM
I suspect that the K2 was originally a Rev. A kit and the original owner also purchased the Rev B upgrade Kit which included new pc boards and the additional components required for the Rev B boards (I recall that a complete set of resistors was included), so there will definitely be some parts left over. The upgrades received a new serial number and that one is close to mine (#3273), which I built as a Rev B upgrade. There is a set of upgrade instructions on the Elecraft web site. 73, Bob N7XY On Jul 25, 2009, at 1:32 PM, H. M.

I must admit, parting with 4991 was not as easy as I thought, but I know it will prosper in its new home. Alas, I have been co-opted by the dark forces and have once again ventured into the realm of the rice box. Perhaps there is a K# in my future - who knows?

Re: [Elecraft] LP PAN and "Point and Click"
Here is one way to pull off what you want... Use 2 PC's and 2 LP-PAN's with your 2 K3's and then user Synergy to tie the two PCs together. I use this at work. I have two monitors and two PC's (one running linux and the other running windows) and I'm able to share one keyboard and mouse between the two computers. I can move my mouse from one monitor to the other and which ever computer has the mouse cursor on the screen is the one that gets the keyboard focus. Its kinda complicated to explain but if you see it in action it works like a single computer with two displays except for the fact that there is a different computer running each monitor. They can both be windows boxes if you want to do it that way and you would for running 2 LP Pan's. You're of course going to need two sound cards too... ~Brett On Sat, 2009-07-25 at 16:26 -0400, E.

Re: [Elecraft] [K3] : Installing KBPF3 in the sub-receiver
You need to be able to remove the sub receiver shielding in order to install the KBPF3, so it does have to come out. BTW, that's where I have mine installed and not on the main. 73 de James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Raymond METZGER Sent: Saturday, July 25, 2009 4:50 PM To: supp...@elecraft.com Cc: Elecraft@mailman.qth.net Subject: [Elecraft] [K3] : Installing KBPF3 in the sub-receiver Hi Elecrafters, I'm planning to perform most of the available enhancements on my K3/100 (#0615) with the objective of removing only once the KRX3 module. The question I have : is it possible to install a KBPF3 module in the subreceiver without removing the KRX3 module (provided, of course, that the two KBPF3 1/2" standoffs are already mounted on the KRX3 board). In the KBPF3 installation manual (Revision D - June 24, 2008), it is clearly stated page 7 that "If your K3 is equipped with the optional KRX3 subreceiver, you must remove the subreceiver module to install the KBPF3 in either the main receiver or the subreceiver." Nevertheless, when I read the KRX3 assembly manual, I have the feeling that it should be possible to install the KBPF3 module in the subreceiver without removing the KRX3 module. Could somebody clarify this issue ?

[Elecraft] Max voltage for a KX1
Hi All, I have acquired two loose 7.2V Li-Ion batteries, the result of the death of my Nikon Coolpix camera. I replaced it, apparently fixing high tech stuff died with the TV Repair shops. The batteries are just fine. Fully charged, they measure 7.45V each. Can I series them to power my KX1? That would be almost 15V, probably not for long, but at the start. These guys weigh less than an 11.7V Li-Poly RC model battery, which would be good for me in the Spartan Sprints, more Q's/lb. I hate to throw them away. 73, Fred K6DGW - Northern California Contest Club - CU in the 2009 Cal QSO Party 3-4 Oct 2009 - www.cqp.org __ 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

It provides reasonable shortwave performance, and its regeneration control can be adjusted for ssb and cw reception. The radio's open layout makes it a good kit for beginners, and the $80 price includes a nice case. The kit assembly even requires the winding of one toroid.

Re: [Elecraft] Need a kit recomendation (off topic a little)
While I agree that a regen kit would be a good receiver, remember that this is for a 5 year old, and a regen receiver requires 'two handed' tuning - one hand on the VFO knob and another on the regen control. A 5 year old needs a single control receiver IMHO. 73, Don W3FPR James Sarte wrote: > I second the MFJ regenerative SW kit.

Re: [Elecraft] New K1 on the way - Band Module Questions
Sandy wrote, and the information supplied by Elecract seems to imply, that: >The 4 band board can be only used on 40/30/20 and 17 OR 15 meters. This board is actually more flexible. It can be used on 40m, 30m, and ANY two of the 20m, 17m, and 15m bands. The assumption that Elecraft makes was that nobody would ever choose not to use 20m. If that is valid, then likely very few would choose 17m over 15m either. >That's the way it's designed and your only option is whether the topmost band >will be 17 or 15 meters. The real choice is which of the 20m, 17m, and 15m bands you will select to assign to the *two* top bands. The common elliptical filter for 40m can be used for 30m since the highest frequency that will be passed is less than two times the lowest frequency. Similarly, the other elliptical filter on the four-band board can be used for ANY combination of 20m, 17m, and 15m, because no frequency the filter will pass will be greater than twice the lowest frequency that it will pass, for those bands. It makes *no* technical sense to select a two-band board for two of the five bands that the four-band board can support. The four-band board has much better filtering than does the two-band board. The two-band board is inferior in performance on any band that is available on the four-band version. The only advantage of the two-band board is that it is cheaper (for good reason) than the four-band board, if the four-band board covers the two bands in which the builder is interested. The *only* technical advantage of the two-band board is that it can be built for the bands that the four-band board doesn't cover. I built my four-band board for 40/30/20/15m, and re-built an old two-band board for 80/17m. That covers all six "official" bands supplied by Elecraft for the K1. The four-band board offers the happy coincidence of double the band coverage, with better RF performance on those bands, compared to the two-band board. Elecraft should make note of that to customers who initially choose a two-band board for bands that the four-band version covers.

[Elecraft] Elecraft CW Net Announcement
Good Evening, Weather has been steady this week, very unusual. Fairly warm but Monday, Tuesday, and Wednesday will be hot with temperatures near 100 degrees. The fire crews have been driving by twice a day for the last week. Fire danger is rising rapidly. I took about a day to straighten out the antennas. Both of the HF antennas were brought down last winter and have been limping along on temporary repairs. Now they are both up again and free from limbs. One of them is in an inverted V configuration while the other, longer one, is a flat top doublet at ~70 feet favoring E-W propagation. Tomorrow I will flip between them so I can work more of you. The solar wind is down a little but who knows what will happen tomorrow? Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP help) Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0100z (Sunday 6 PM PDT) 7045 kHz Stay well, Kevin.

Re: [Elecraft] Li-ion battery pack for KBT2, K2
Johnny, Some have done this, but the Li+ cells are prone to catch fire, so it's risky. SLA is well understood and less risky. They can catch fire when over charged, of course, but also when over-discharged. Some people are reporting the A123-manufactured Lithium Nano-Phosphate cells are safer than the Li+ and LiPoly. They don't catch fire when over-discharged, for example. Unfortunately, they don't quite fit in the K2 battery case, at least now in a way I can figure. There are also non-A123 brand LiFePO4 cells which you should be able to get in HK easily. These are 3.4v and a better fit (4*3.4=13.6, max 14.4v) for 12v radio electronics than the ~16VDC full charge of Li+. They are thought to be safer than the Li+ cells, but the no-name brands don't necessarily have the same testing as A123 brand, so again it's more of a risk than SLA, though less of a risk than Li+. LiFePO4/A123 have excellent power density, and can source 60 amps easily, so they must be fused close to the pack. They don't have as good energy density as the Li+ technology, but with the K2 that's less of an issue since its RX draw is so low.
