Re: [Elecraft] K3: advice about options to buy?
A short post to thank everyone for all the great help with thinking through my K3 options. I received a lot of very clear advice, both on and off the reflector, and I feel much better placed now to make a decision. Thank you, everyone, for your interest and for generously sharing your knowledge. I look forward to a having K3 contact with some of you - perhaps very soon. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-advice-about-options-to-buy-tp5891397p5894810.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] K2 MDS numbers off
Brian, Your K2 seems to be somewhat deaf based on your MDS measurements. I would recommend that you do the steps in the K2 manual under Receiver Signal Tracing to identify the failing stage. Once the failure point is identified, we can offer additional assistance. 73, Don W3FPR On 1/5/2011 8:10 PM, Brian - N5BCN wrote: > Hi all, > > I attempted to calculate my K2's (S/N 6800) receiver sensitivity using an > XG2, but I'm getting numbers way off from what are listed in the XG2 > instruction sheet. > > Using a Fluke 117 multimeter, I'm measuring S+N = 0.132 Vrms and N = 0.034 > Vrms, which I calculate MDS = -119 dBm.

[Elecraft] K2 MDS numbers off
Hi all, I attempted to calculate my K2's (S/N 6800) receiver sensitivity using an XG2, but I'm getting numbers way off from what are listed in the XG2 instruction sheet. Using a Fluke 117 multimeter, I'm measuring S+N = 0.132 Vrms and N = 0.034 Vrms, which I calculate MDS = -119 dBm. I'm probing the external speaker leads (I can't figure out how to get a reading from the headphone or ext speaker jacks). I'm using the set up parameters recommended by the XG2 instruction sheet: AGC Off, RF Gain maxed, Att Off, Preamp On, filter 500 Hz, etc. The K2 appears to be performing normally except for strange CAL S LO/HI behavior. Apparently, there might be a problem with the K2's receive sensitivity which is causing problems with the CAL S LO/HI. Any suggestions would be most appreciated!!!

[Elecraft] diversity
I installed the KXV3A today and while I had everything torn apart, I moved the cable on the KRX3 sub-receiver from BNC to J43 so that the sub-rx could listen on the idle transmitting antenna. All works great, and I am having fun trying diversity reception. But here's my question: My two antennas are located so each is in the other's null, but they are not far apart, maybe 50 feet at most. When I transmit, I don't hear any carrier-operated relays or see any adverse reactions, but I'm still not sure that it's okay. The manual sez "well isolated," but what I'm looking for is some objective way to test or measure. Can anyone tell me how I can establish for sure that I can, or cannot, transmit on A when the sub is connected to B, and vice versa? 73, Tony KT0NY __ 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

Hi Bruce K1FFX, Yep, this is also pretty much similar to what I ended up doing - gently bending the leads down below the body of the miniature RFC package, letting them rest elevated about 1mm above the PCB. Good picture - shows the detail of it, and good that there was a backstory to this and I was not the only one loosing my mind over such otherwise perefect build record. May I suggest you still check (as mentioned in the manual) with an ohmmeter that there is good DC contact through each of the RFC 6-7-8-9 to be sure that the bending of the leads does not cause for internal breakage ? 73' Brian OZ2BRN Den 05-01-2011 21:52, K1FFX skrev: > I believe this is what you are looking for: > > http://www.elecraft.com/Apps/Builder%20Alert%20Installing%20Small%20Chokes%20Rev%20B.pdf > > I found it after breaking one of the leads off RFC9 (!). > > You can have a look at the photo at: > > http://build-k2.blogspot.com/2010/12/rfc9.html > > Cheers - > > Bruce > > - > Bruce Rosen > K1FFX > __ 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] K2 BFO Drift / Filter Alignment
I think I've nailed it down as an interaction between the bottom cover and L33, which mounted on that rubber spacer on the bottom side of the RF board. I can get the same BFO shift effect by barely pushing on L33 with an insulated tool, for example. I took the cover off and measured clearances, and L33 seems to be well below the height of the two spacers. However the cover has a bit of flex to it (maybe made worse by the tilt stand), and pushing on the bottom cover does cause the BFO to shift, although it does not, AFAIK, actually touch L33. Not clear that there is anything to be done about it. Now that I know, I'll just need to avoid pushing on the case, particularly from the bottom. Will realign filters once more and see if they stabilize.

Re: [Elecraft] K2 BFO Drift / Filter Alignment
Bruce, Make certain that the two standoffs are mounted on the RF board and that the bottom cover is installed with all 6 screws. When properly secured, and with the tilt bail in either the up or down position, the bottom cover should not move with pressure on the K2 top. Be certain there is no "rocking" motion with the tilt bail extended - if there is, it could cause your problem - loosen the bail feet screws a bit and reposition to correct any "rocking". 73, Don W3FPR On 1/5/2011 4:23 PM, K1FFX wrote: > Hi, Don - > > Thanks for the hint.

Re: [Elecraft] win 7 32/64 bit
Are you sure its Windows "Permissions" blocking you (which makes no sense)? If one program allocates the serial port then other programs are blocked from using it. Often, even after closing one program, you must reboot in order to make the serial port available to another program. I simply use multiple serial ports - actually multiple serial-to-usb adapters, one for each application. I don't think there is any administrative-level requirements for using a serial port and every problem I have ever seen in Windows regardless of version, has been traced back to a particular program allocating the serial port followed by a second program being blocked by the first programs resource lock.

Re: [Elecraft] Filters and Configuration Questions
I do not know the details, but there is some sort of limitation which prevents the synthesizer from reliably acquiring lock with RX bandwidths greater than 2.8 kHz. I ran into a firmware bug about a year and a half ago (since fixed) that was allowing my 13 kHz FM filter to be selected in CW mode. The result was the RX would go dead intermittently when returning from TX. At that time Wayne explained that the permanent fix for the problem was to correct the firmware so CW mode never allowed a filter > 2.8 kHz to be used. 73 -- Joe KB8AP On Jan 5, 2011, at 5:47 AM, Bob Naumann wrote: > ... > Regarding the 6 KHz filter, why can't it be selected to receive CW? > > I think it was permitted earlier firmware- wasn't it?

Sadly, this is true, and until I bought my K3, no one who develops Hamlib code actually had a K3. I have made some changes with more to go that will be in the next Hamlib release, 1.2.13. This does not help those K3 owners stuck with an older version. Hamlib development relies on volunteers to either write the backend code and test with their own hardware or other volunteers who can test prototype code with their radios. Fortunately, the gap is closing bit by bit, thanks to help from many hams. Hamlib is a voluntary project and few of us are professional programmers. That has certain consequences for the project. > It's up to the maintainer of the Windows port of HAMLIB to fix the > issue. Actually, there is no "Windows port" as it were as the DLL for Windows is generated from the exact same sources used to compile the binaries for the *nix versions. So the changes made to the K3 and K2 backends before the next release will be in the Win32 release as well. The situation is complicated by whether an application has Hamlib compiled in it statically, or it is dynamically linked. For those wishing to test the latest code, there is a daily SVN source code snapshot at: http://n0nb.users.sourceforge.net For those willing to do so, a Win32 DLL can be compiled from the snapshot.

Re: [Elecraft] win 7 32/64 bit
Shut off account user control, try it then. If that fixes it, then look to the firewall settings. Running without UAC is a dangerous thing to do when you use the internet. So look to giving the permissions as an administrator. Incidently, I never use home addition so can't help you there. Good luck.

Re: [Elecraft] K2 BFO Drift / Filter Alignment
I'm wondering if there was any resolution to this problem, first posted just over a year ago, since I observe what I think is the identical problem with my K2 S/N 6982. A related symptom was obvious BFO shift when pressing down on the top cover just behind the A=B push button (for example, to hold the K2 steady while turning off AGC or checking current XFIL setting, i.e., an operation that requires two button pushes). Some loosening and moving of the side panels seems to have resolved this second symptom, but the BFO shift out of the filter center frequency persists. I'm currently working on KPA100 construction, and would really like to resolve this before installation (still several days away ... now looking at T1 installation!) and would appreciate any thoughts on this BFO shift. Meanwhile, have started tracking BFO freq/Pin 14 voltage per Don's suggestion.

It only affects Prolific USB to serial adapters. FTDI adapters and real serial ports are OK as far as I know. I am only an amateur programmer so others may know better but I believe that the Prolific adapters only work reliably with software that uses the MSCOMM.OCX component for serial port access. This basically means programs written using Microsoft development tools. The programs mentioned above are open source software developed using open source tools which use open source libraries for serial port access. Open source development tools do not support OCX components because they are Windows specific so ham software developers who use these tools cannot use this component to solve the problem. Nor can they fix the problem themselves because they don't actually write the serial port code. All they can do is complain to the developers of the serial port libraries who reply "it works fine with a real serial port so there is nothing wrong with our code, it is the Prolific adapter serial port emulation that is at fault." Which, while not being the helpful response you might expect from the developer of a component if you had paid good money for it, is nevertheless true. - Julian, G4ILO.

Re: [Elecraft] K3 Software for RTTY
Just use N1MM with the MMTTY plug-in and be done with it. You clearly have a computer, every compute made seems to have a sound card good enough to support this task. Two audio cables, ASFK-A using VOX and you're good to go. Be sure to set 45 BPS tho. Pick a mark frequency and be sure to set the K3 and MMTTY to the same.

Re: [Elecraft] K3 filter options
Like Dave and Jim I would recommend 2.7/1.8/400/200 along with a 13 KHz (FM) filter if needed. I have tried the 1.5 KHz narrow SSB filter and find to too tight in nearly all conditions ... the 1.8 KHz will be used more often and the 1.5 provides very little added benefits in really crowded conditions. I find the 400 Hz filters (measured bandwidth 420 - 450 Hz) to be significantly better than the 500 Hz, 5 pole filters (measured 480 to 490 Hz) and the 200 Hz filter is a useful "narrow" filter when needed compared to the "250 Hz" filter which measures more than 350 Hz at the - 6dB points. With 2.8/1.8/400/200 Hz, my only wish is that there were three more slots or at least that I could use the 13 KHz filter for AM and ESSB transmit (without resorting to calling the 13 KHz filter a 6 KHz filter). 73, ...

Re: [Elecraft] Latest Sherwood table
It has been a known (documented by W8JI with fix) issue since the FT-1000D. The noise blanker contains a dual gate MOSFET connected to the IF that runs all the time. Instead of disabling the MOSFET, the second gate is simply biased into an "off" state when the NB is turned off. Unfortunately this allows the first gate to be overdriven by strong signals which creates IMD that is coupled directly back into the IF. The FT-2000 uses the same noise blanker circuit as the FT-1000, FT-1000D, FT-1000MP, etc. 73, ...

Re: [Elecraft] win 7 32/64 bit ... caution needed...
Much as I hate Microsoft Windows, I have to admit that if you just want a computer that works, Windows is the best choice. If you don't mind climbing up a steep learning curve and spending hours playing around with the computer trying to get everything to work, then Linux is the way to go. I use Ubuntu Linux on a computer that is dedicated to email and web surfing. By keeping my Windows machine (that has all my important stuff on it) not connected to the Internet, I don't have to worry about viruses. I would like to be able to use the modem on the Linux machine as a backup for when my Internet access fails (which happens on a fairly regular basis). But, despite reading through all the help files and spending several hours on it, I have never been able to get the modem to work. It works fine under Windows on the same computer (dual-boot Windows and Lunux). Took me about 5 minutes to activate it. When I first installed Ubuntu, everything else worked fine. But after one of the updates, the sound quit working. I Googled the problem, found a couple of helpful troubleshooting information sites, and spent several hours trying various things but was never able to get it working again. Also, I use a KVM (keyboard-video-mouse) switch between the two computers. Ubuntu worked fine with it at first, but after one of the updates I now have to completely boot up with the KVM switched to that computer or it hangs up. And again, a couple hours of troubleshooting did not cure the problem. No doubt, given enough self-study and hours of messing around I could eventually solve those problems. But frankly I have better things to do. Computers are not a hobby for me. I don't enjoy messing with them. I just want something that works. So I hold my nose and use Windows.

Re: [Elecraft] K3: advice about options to buy?
John says he is a casual operator, ie not really interested in contests. I suggest any additional filters (apart from the General Coverage BPF ) are probably unnecessary for his style of operating. As I understand it, the filters are not there to determine the operating receive bandwidth, but are to protect the A/D from overload. This overload is unlikely in his operating environment, ie not contending with super - heavy QRM unless he has a very close neighbour who persistently creates that sort of signal. The K3 has a superb adjustable DSP filter that goes all the way down to 50Hz with little or no ringing plus the new APF for very small signal enhancement. Save the money and spend it on something else like the auto-atu which is superb.

[Elecraft] [P3] Filter Width Brackets
Is it possible to turn off the filter width brackets in the display? At times when doing weak signal work they can obstruct the signal spike on the display, especially when having the filter width cranked down to 100 or 50Hz. I'm not talking about the center line.

Re: [Elecraft] K3 Software for RTTY
Robert, While the K3 has the capability to do RTTY (and CW and PSK31) from an ASCII text stream, there are few applications that support it. K3 Utility does it, but that is not a logger. You will probably have to use the audio cables from the soundcard and use the AFSK A Data Mode. Maybe someone else will know of a ham application which sends the ASCII data stream over the RS-232 connection. 73, Don W3FPR On 1/5/2011 1:10 PM, robt...@comcast.net wrote: > With the ARRL RTTY Roundup coming up, I'm having difficulty choosing a > software control and logging program. > > N1MM needs audio cables to and from the K3 for RTTY and yet the K3 user > manual states “The K3 directly supports CW/PSK31/RTTY ASCII text transmit and > receive via its RS232 port.” I do have the RS232 to USB cable installed .

Re: [Elecraft] K3: advice about options to buy?
Hello John, I would get the KTCX03-1 option instead of the 2.8 filter. You won't notice the difference between the filters. I have two K3's one with the 2.7 and one with the 2.8 and there is no real difference between the two. I would get the 500hz CW filter for starters. When you start working serious DX CW you can get one of the narrower filters for that. That's my opinion. I could be wrong. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Life Member 35102 ARRL Life Member Retired Professional C# Software developer http://www.n5ge.net On Wed, 5 Jan 2011 01:11:44 -0800 (PST), VK7JB wrote: > >Hello group, > >My mouse is hovering over the "Add to Cart" button for a K3/100 modular kit. >I'd really value some candid advice about options before I commit. > >My situation: I'm a casual operator, data modes, SSB and CW.

Re: [Elecraft] win 7 32/64 bit ... caution needed...
John,
You are correct, GRUB is difficult to remove, In the past, I have given
up and just format the hard drive and then re-load.
However, I recently discovered on the Ubuntu website a loader that loads
Ubuntu in a Windows computer. It can be removed with Windows Add/Remove
Programs. It seems to be a clean way to go for those who want to try
Ubuntu.

Re: [Elecraft] Filters and Configuration Questions
I'll vote with Bill here. Since the CW envelope in the digital number stream is pristine, the filters and any envelope delay can only distort it. In the case of the 2.7, the delay is far enough away frequency-wise from the signal to be insignificant. Given that the filters are subject to manufacturing variance, and a super clean filter would be prohibitively expensive, to use a narrow one would involve some kind of routine to "reverse modify" the CW envelope number stream to the transformative opposite of the distortion, so that the delay undoes its distortion by distorting it, kind of like two amps in series that together have less IMD than either alone, common enough. While that is attractive in a geeky way, it would have to be done on a bench for the exact filter. Given the results we have, aside from unfortunate and now-fixed issues such as the microphonic sensitivity of the VCO boards, CW is remarkably clean. It's the only rig available to me I would consider using to park on 7000.25 as a run frequency. It MAY be that Wayne et al have some of that reverse magic in effect, but I haven't heard of it. Trying to fix something that ain't broke? 73, Guy. On Wed, Jan 5, 2011 at 11:19 AM, Bill W4ZV wrote: > > > P.B.

Re: [Elecraft] win 7 32/64 bit ... caution needed...
As a long-time Unix and Linux user, I have the following comments...
1. It is indeed possible to have a dual-boot machine running both WIN
(e.g. WIN 7 or WIN XP) and Linux.
1a. The bootstrap loader ("GRUB") is not easy to remove, and I would
highly recommend you have a complete bit-image (not just a data-file
backup!!!) copy of your original, functional, system, including programs
and OS, before you try to install Linux.
2. Some amateur radio programs (e.g. FLDIGI) have very good versions
that run under Linux.
3. Some UBUNTU distributions load and run on my particular machines
(usually I use a Dell XPS 420 running WIN 7 Ultimate (32 bit)), and
others do not load properly. In particular, the last Ubuntu distribution
that I was able to load and use successfully ON THIS MACHINE was
10.04.1. This seems to be somewhat dependent on the machine.
4. Various Red Hat (Fedora, etc) distributions work, but are a tiny bit
more difficult to install and extend.
5. It is not true that there are no virus issues with Linux. There are
specific Linux viruses, but since Linux is much less popular than
Windows, the creeps that write such malware have paid less attention to
it than to Windows. I speak from the experience of having to rebuild a
Linux OS that was virus-infected. Vide:
http://en.wikipedia.org/wiki/Linux_malware
6. "Drivers" are still an issue. Ubuntu 10.04.1 would not recognize my
sound cards on the Dell XPS. This is disastrous for programs that
utilize a sound card for AFSK, etc. Red Hat's distribution would. Go
figure.
In the best of all possible worlds, Linux is fine. It is small, very
reliable, almost virus-free, and when used with a windowing shell, it is
almost like a Windows OS. The main problem you might encounter is that
there is a paucity of applications for Linux, for the same reason that
the malware builders don't spend much time on Linux.
If you try to operate from a console window in Linux, you are faced with
the same situation as with Unix...the command structure is quite
different, and there is a bit of a learning curve. The situation is not
as utopian as is sometimes said. Be prepared, in the worst case, to
rebuild your Windows from scratch (i.e. from your bit-image backup). It
is not too hard to get into a situation where a machine won't boot at
all without some outside help.

If the CW Tx frequency is not reasonably centered in the filter passband, poor keying quality reports will result, especially if placed on, or near the upper or lower skirt of a crystal filter. This asymmetrical group delay issue plagued the Omni VI+ as the CW carrier frequency was placed right on the skirt of the 2.4 kHz @ 9 MHz filter. The placement of the Tx BFO frequency near the filter skirt was done in order to better accommodate variable CW Tx offset in the Omni 6+ design. In the Omni V, the CW BFO was fixed and located about 400 Hz above where Ten Tec placed it in the Omni 6+. That shift of a few hundred Hz made all the difference in the world. Among several other contributions to poor keying in the Omni 6+, including a poor ALC design that mutated from the Omni 5 and 6 (non plus), the primary culprit was the BFO placement near the skirt of the filter. The overall solution included filter replacement with a custom 2.8 kHz filter from INRAD and re-working the ALC with a handful of components. I ended up bypassing the filter with a hard wire in CW Tx. Passing the BFO through the filter simply isn't required when the rig is capable of generating a clean waveform. Plenty of old homebrew boatanchor rigs were capable of producing a high-quality RF envelope and didn't rely upon ALC nor a filter to pass the CW waveform. True, just as many homebrew rigs produced horrendous signals on the air. Since keying bandwidth is a function of the RF envelope shape, I'm not sure why anyone would want to narrow the K3 filter on CW transmit. As long as the ALC is stabilized and the slope is reasonably smooth and absent sharp discontinuities, all a narrower filter will accomplish is to produce envelope distortion if not placed squarely in the center of the filter passband.

Re: [Elecraft] K3: advice about options to buy?
NR4C's advice on an additional filter if you plan on doing much SW or MW listening is good, and something I overlooked in my first response. While you can achieve quite good results using USB or LSB in conjunction with the 2.7 KHz roofing filter, a wider filter for use with AM RX will be more satisfying if you plan to do much of it. But I would recommend the 15 KHz "FM" filter for this purpose rather than the 6 KHz filter. Only get the 6 KHz if you plan on TRANSMITTING on AM. For RX, the 15 KHz filter will allow you to obtain the full 10 KHz bandwidth on BCB stations. And, you can always narrow it, as desired, by using the DSP filter. 73 Craig AC0DS __ 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: advice about options to buy?
OK, you are just about to buy, and want ideas. Here goes. You've indicated the General Coverage module. If you are going to get that, I'd suggest you also get the 6khz filter so you can take advantage of all the AM broadcasts you'll be hearing. The 2.8/7 filter just won't work with AM. I felt that the K3 was probably the best radio I could find and decided to go with the 8 pole filters all the way. Bought the 2.8-8pole right off the bat. As I buy filters, i'll only get the 8 poles. Figured I'd always wonder if they would have made a difference later. I like the DVR a lot. You may think about this but it is easy to install as you go from the beginning. By all means get the ATU option. The KAT3 is the best ATU on the market for a built-in ATU. It is fast, very quiet and accurate. And it will tune just about anything. I'm not sure what i think about the high end ref oscillator. I did not get this, and my radio is as accurate as I can tell, and I don't notice any drift. One item I'd suggest is the P3. I just got mine and I think it makes the radio a lot more fun to operate. And, it is great to be able to see what is going on on the bands. Don't forget you need the KXV3(a) interface module to make this work. It also opens up the option of a rec only antenna. As for other filters, I'd suggest waiting until you find you need them. I so far have only the 3.8 standard one. i'm about to buy some but can't determine what ones to get. The DSP filtering is so good, it is hard to imagine that a real filter will make a difference. There, I've spent about $4000 of your hard earned money, but you Will have a radio you'll be proud of, And you'll be working with a group of developers who are on top of pack.

This is a waste of money for a casual operator and is unnecessary for HF operation (but possibly needed for some VHF uses). If your shack is kept at a relatively constant temperature and you allow a reasonable warmup time, your properly calibrated VFO will typically be within 1 Hz at HF even with the standard TCXO. 2. You will need a CW filter if you ever expect to have S9+25 signals within ~3 kHz of your CW or digital frequency. If you don't have one, your AGC will "pump" when strong signals are near. For casual operation, you might consider the $90 5-pole 500 Hz filter instead of the $131 8-pole 400 Hz. 3. For casual operation the 2.8<>2.7 filter swap is unnecessary (I don't have this in either of my K3s). 4. I don't have a KAT3 in my shack K3 since I'm always driving a tuned input linear and my antennas are resonant anyway. However my K3 configured for portable/expedition use does have the KAT3. At $300 (kit) or $330 (assembled), it's worthwhile to think carefully about whether you really need an ATU. The beauty of the K3's modular configuration is that you're not forced to pay for options that you may seldom if ever use (e.g. AM, FM, general coverage in my case). However, unless money is no object, careful consideration before you place your order can save you a lot of money. Some people say the K3 is a $4-5k rig, but it need not cost that much if carefully configured. For example my shack K3 cost about $3k (even with KRX3) and my portable unit cost about $2.4k (including KAT3). 73, Bill P.S. I would strongly suggest you build the kit version. You'll not only save $300 but you'll learn a lot in the process and will not be afraid to do hardware updates, make repairs or add modules later. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-advice-about-options-to-buy-tp5891397p5892027.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
[Elecraft] Filters and Configuration Questions
I've asked about the 2.1 filter before, but here it is again. Will the K3 configuration be changed to allow the selection of the 2.1 filter for transmission purposes? If not, aside from it being some amount of work to allow this, is there a technical reason why not? In other words, would my signal be "bad" if it was routed through the 2.1? I really want to have the following 5 filters in my K3: 6k, 2.1k, 1k, 500, 200. The 2.7 wastes a filter slot since all I use it for is to transmit. Regarding the 6 KHz filter, why can't it be selected to receive CW? I think it was permitted earlier firmware- wasn't it? This one really puzzles me why this would be restricted. I like listening to a wide passband and narrowing it down only as much as necessary - sometimes 6 kHz is OK.

Re: [Elecraft] win 7 32/64 bit
Ron, I thought I'd try Linux, so I installed "Julia Mint" on my older (2.1 Celeron) flaptop. I cannot get it to connect to the internet. I had a LOONG exchange on the Mint groups, and no joy. It only fills a portion of the screen. The download was very long, and it was a real trial to burn the ISO. Now I find that apparently there's no way to un-install it. For all the talk of the superiority of 'open source' software, I find it's quirky and un-supported, and the development and bug-fixing is too diverse to be effective. When I buy a car, I don't want to have to wind the armature for the starter motor before I can drive home. :-D If you have any hints for getting it going I'd like to hear from you (off list). 73, Mike NF4L On 1/4/2011 7:36 PM, tuxman wrote: > Bob, > > if you are that concerned about windose, why not look into Linux.

[Elecraft] K3: advice about options to buy?
K3 is said to be having a better DSP filter than its competitors. Therefore, even for CW operation, the DSP could further narrow the BW hence additional crystal filter such as 400Hz may not be necessary under most of the circumstances. KAT3 is necessary. Under most circumstances, ATU can both act as a preselector and an additional protection between the radio and antenna. No matter whether I have a matched antenna, I always engage KAT3 and don't mind the tiny insertion loss. In case, there were something wrong with my antenna which I did not realise, I could sacrifice my KAT3 to save the radio. I do not favour the proposition of no ATU for a matched antenna. cheers, Johnny VR2XMC 寄件人﹕ Arie Kleingeld PA3A 收件人﹕ elecraft@mailman.qth.net 傳送日期﹕ 2011/1/5 (三) 6:24:11 PM 主題： Re: [Elecraft] K3: advice about options to buy?

It works great for most things. I one issue I've run into and haven't been able to resolve? When I'm running HRD, I can't connect to QRZ or the DX windows. Heck, I can't even register the software. I can't hook to any I/O ports because Windows permissions is blocking me. I've been reading everything I can find and have tried many different things to get around this but haven't found the answer. SO, can any of you pro Win 7 folks point me in the right direction??

Re: [Elecraft] K3: advice about options to buy?
Hello, John... I have just such a device as the one you describe...a K3/100 without the KTCX03-1 and with the normal factory filters. The only serious add-in that my box carries is a K144XV internal transverter (more on that anon). I operate a little SSB, more CW, and a lot of other digital, e.g. BPSKxx (31 and 63 mostly), Olivia, Feld Hell, WSJT, etc. I find that this combination works wonderfully for me. The 400 Hz filter is fine for the most demanding CW, but mostly my machine stays with the wide filter (FL1). Now, about the internal 2 meter transverter. This was a Christmas present from the wife. It installed very well, and seems to function superbly. Unfortunately, the 10 watt (actually 9 watts in my case) is not sufficient to drive my 2 meter amp to more than about 60% power. I would have been better off with the external transverter, and I may just get one. The only downside to the external one is that it makes portable operation a bit more complex...more cables, more pieces, and so on...but one could argue that it is unlikely that I would carry the external transverter anyhow, since the high-power 2 meter amp and its gargantuan power supply (60 lbs) are never going to go portable. You can see that I am bedeviled by this matter. [not the Tasmanian kind!] I believe you would be perfectly happy with a plain-vanilla version of the K3/100. John Ragle -- W1ZI P.S. Wasn't the K2/100 a blast? I also built one from scratch and loved it. During a misguided fit of anti-Luddite sentiment, I swapped it off for a Flex 3000, which was a SERIOUS mistake, rectified by purchase of my K3/100. I won't say that I sent the Flex to Botany Bay, just to San Francisco Bay... = On 1/5/2011 4:11 AM, VK7JB wrote: > Hello group, > > My mouse is hovering over the "Add to Cart" button for a K3/100 modular kit. > I'd really value some candid advice about options before I commit. > > My situation: I'm a casual operator, data modes, SSB and CW.
