Re: [Elecraft] [K3] KY Command
Interesting that you bring this up Julian. I've been using KY mode from HRD DM780 but it just wasn't 'conversational' enough for me - so today I've gone back to using the trusty Winkey to generate CW. Maybe it was a function of VOX timing, but at 25wpm, I'd send something like de callsign and the d would be sent and then a pause, then the e etc. Embarassing! I could get more scientific about this, but the Winkey seems to work fine ... rgds, Julian VK4CMV -- View this message in context: http://n2.nabble.com/K3-KY-Command-tp4593734p4596823.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] [K3] KY Command
Hi Julian. Perhaps it has something to do with the way HRD implements KY keying? I have used it for CW for years, first on the K2 with my old program K2Net and then on the K3 with KComm and I have never noticed the issue you mention. KY keying still works fine on CW, it is only the digital modes PSK D and FSK D that appear to have a problem with it. - Julian, G4ILO.

Re: [Elecraft] For you Anti-Scopes
I'm sure it could be done, and I'm sure the programmer who wrote it could justifiably feel satisfaction at the results he got, because for sure he would have put a lot of effort into creating it. The question is whether those who simply downloaded his program and used it would have their enjoyment if the hobby and sense of achievement enhanced by so doing? I think the fishing analogy is an apt one. No-one would advocate going back to using a stick and a bit of string (although some in this thread seem to be suggesting an equivalent of it) but surely it is undeniable that a radar that could let you see where all the fish are would remove the sporting element of fishing? Isn't ham radio like sport fishing, something done for the pleasure and skill of it? I get the feeling that for some people it has become more like commercial fishing and anything that can maximize your catch is good. Different strokes for different folks, I know. But I wish I could understand what they get out of it.

Re: [Elecraft] K3 and the subreceiver
Two simple benefits: 1. With just one antenna, when a DX station is working split (transmitting on one frequency, listening on another) you can listen on his receive *and* transmit frequency simultaneously when you are trying to work him. This makes it much, much easier to figure out his listening frequency and pattern to adjust your transmit frequency - gets you in and out of the pileup much faster. 2. With a separate antenna on the sub-RX, you can turn on diversity RX: listen to the same signal on the same freq with two different antennas. Fades on one antenna are often filled in by rx from the other antenna. Especially neat on weak signal bands like 160. Definitely worth the $$ to me. 73, John K3TN -- View this message in context: http://n2.nabble.com/K3-and-the-subreceiver-tp4593879p4597629.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] K3 chirp
Just to close this subject maybe. In addition to the chirp I found on my K3 on 3526 kHz I was told by others (Bruce N1LN) that they had found chirp on 14030.5 kHz. Bruce cured it by adding a resistor+capacitor to the Synth Board and load a specific f/w file and Bruce praises the support from Elecraft! I checked mine, and indeed I also found chirp in a 400 Hz range around 14030.6 kHz. It was even worse than the 80m chirp and over a much wider bandwidth - it sounded real bad. I then first soldered in a 55 ohm resistor on the KSYN3 board across R20 (as I was originally told to try by Gary). It took away the chirp on 80m but did not improve much on 20m. I then received the specific f/w file hfpf0108.hex from Elecraft and also the suggestion to solder in a resistor + capacitor combo to terminate the xtal filter on KSYN3. I decided to try the f/w upgrade first without this termination, since I was not too happy with soldering on the KSYN3 board. I placed the hex-file in the directory with the (latest) firmware files and loaded all new files into the K3 and ran the VCO MD Cal. This eliminated the 20m chirp problem. I have not yet checked every band and every frequency - which requires about 6000 measurements where you have to tune both the K3 and a separate rcvr ;-) The solution of this problem gives me good reason to also praise Elecraft support! 73/OZ4UN Poul-Erik __ 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] K1 VFO Range Question
Steve, All you need to do is tack an NPO capacitor in parallel with the 68 pF C2 - try different values until you find the range that yo want. After finding the range, then adjust the turns on L1 to place the lower end of the range where you want it. No other tuning should ge required, although you could re-peak the bandpass filters on transmit (use a low power level like 1.5 watts). If it is working well now, do not movethe adjustments far - just re-peak them. If you have the 4 band board, be certain to do the bands in the proper order - 30 meters before 40 and 15 (17) m before 20. Be aware that if you have the 30 meter band on that K1 you will lose coverage of most of the CW portion of 30 meters by moving the bottom of the range upward - all bands will move. 73, Don W3FPR Steve KS1G wrote: Hi! I've had an early (S/N) K1 since mid-2001; bought it already built from the original owner, has 80kHz bandwidth. Am I correct I just need to change C2 and re-peak the filter board to widen the range? Is tacking another cap in parallel practical? I'm also considering just re-aligning the VFO coverage to hit, say 7.030 or so and up, as my cw speed can't keep up with the faster ops below 7.025 or 14.025 anyway. Either way, any gotchas to look out for before I start disassembling a working rig to fix something that may not need fixing? I assume I have to remove the antenna tuner and 2-band filter board before I can work on the VFO. 73 de Steve KS1G __ 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

Let's be reasonable though - the Flex is not a piece of junk just because it's in second place on the Sherwood list. There's a whole lot of good radios behind the two of them further down the list.

So many Flexradio users have PC problems and hangups. I would not go near this concept. At least if you plug the P3 in it wont hangup. You certainly wont have to spend months seeking out a good motherboard that wont cause hangups or stutter. I dont see Agilent bringing out test instruments with a PC for the main interface. They dont do this for for very good and valid reasons. Ham radios are exactly the same in nature, they need a front panel with knobs and buttons. I dont mind using my Perseus for casual monitoring and testing tasks, however when tuning the bands for a long period of time I just shut the thing off and use a real VFO knob. Its the most efficient device ever invented for tuning, its the equivalent of the wheel for ham radio! We all know there's little point in reinventing the wheel! Hail the VFO Knob!

Re: [Elecraft] W9OY on P3
That's a very interesting observation, Don. I recently got a new computer but I didn't get it to have it bogged down by a CPU hog quite this soon. As well as the cost of the computer you also need to include the cost of the high end sound card. The P3 is looking more cost effective by the minute. Don Wilhelm-4 wrote: I just found that setting up Flex software is not a trivial task. I spent 2 days getting my software installation for my Softrock/Z1 - E-MU 202 soundcard addition to my K3 working. It did not go smoothly, but the document that Larry Phipps wrote certainly provided great help. It is not a plug n play operation. As a side-note, I am using a 3.0 GHz Pentium 4 with 1 GB of RAM, running WinXP Pro and the CPU utilization ranges from 50% to 90%, so anyone thinking of choosing this alternative with a lesser computer had better think about a new computer first. The Softrock solution is inexpensive *unless* one has to purchase a computer too. If one includes the computer cost, the P3 is inexpensive. - Julian, G4ILO.

Re: [Elecraft] For you Anti-Scopes
Although I operate almost entirely in CW my bandpass is typically set wide open. However, this is effectively only about 2 KHz max, which is not nearly wide enough when you want to hear what is going on around you on the band. I concur with this statement. I am used to using my ears as a band scope, and the K3 with the 2 KHz bandwidth limit in the CW mode sometimes makes me feel like I have blinders on. This limit is not present in the Data mode, so it is hard to understand why it is necessary in CW mode. Still a great, versatile radio, but with a curious limitation.

Re: [Elecraft] W9OY on P3
Quite so, and if I could order one of the new QRP 1500s for what they cost in the US rather than what we'll end up paying over here I'd be tempted to get one just to try it out. Most of the issues seem to be a consequence of the software implementation rather than problems with the idea of SDR itself. Installing net frameworks and virtual audio cables - let's face it not all radio enthusiasts are computer wizards and even those of us who are supposed to be knowledgeable are not immune to blue screens of death and the like. And I think the CW latency issues I've read about are due largely to the fact that Windows isn't a realtime OS so you need a powerful CPU and plenty of buffering to ensure that pauses don't occur when the OS is busy doing something else. If the software side came on a dedicated board with its own processor and OS then you wouldn't have to worry about any of that, except to update the software now and again. But hang on, isn't that more or less what the K3 is, except you get knobs and buttons as well? Arie Kleingeld PA3A-2 wrote: The flex radio's are fine and very good radio's.

Re: [Elecraft] W9OY on P3
Hi, I don't think anybody is saying Flex is a piece of junk. Its receiver's number two position on the Sherwood list is outstanding and the audio on the air is the best there is. I have worked a number of them and they always sound great. But the software is not for the faint of heart. I use LP-PAN with my K3 and the modified PowerSDR software (one of the several versions). I see on Larry's Yahoo group that there is now a new version out with a resulting explosion of activity on the group. I am not ready to jump in. The version I am using is reasonably stable (except it always loses communications with the K3 after a while) and I am not ready to fight with not-so-plug-and-play installation of the new version, even if the new display is a little prettier and the elimination of unusable buttons is welcome. I don't agree with W9OY that the P3 looks like a joke, but really it doesn't come close to the gorgeous high resolution PowerSDR panadapter display on a high resolution monitor. But they really need to work on making that software a little easier to install and maintain. It is really the only serious knock against the LP-PAN panadapter solution.

Re: [Elecraft] W9OY on P3
Well, I don't know about anyone else but ham radio is one of the activities I partake in to get away from computers ;). But then again I'm a software engineer and by the end of the day have pretty much had enough of fighting with Windows and .NET, etc. hi hi and want to do something else. Tho all that said, I looked at the Flex briefly not too long ago when I was shopping for an HF rig. I had to reject it right away because it only supported Windows (Im a MacOS X user). Don't know if that's true anymore or not. Seems like an interesting idea; they just need to choose a better SW platform than Windows/.NET ;) Also, the performance no's of the Flex 5000 look really good too. But then again, you can have that and a little more with the K3 _and_ not have to fight someone's Byzantine array of SW drivers, cables, endless configuration options and SW with who-knows-what wrong with it with every release JMO, LS W5QD, K2 #6882 -- View this message in context: http://n2.nabble.com/W9OY-on-P3-tp4596769p4598330.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] [K3] Separate PTT outputs for HF, 6m and Transverters
Hi all, I have built a number of interface boards for my K3's that some of you may be interested in. Since a K3 only has one PTT output, I have built an interface board that takes the LP Keyout, DIGOUT0 and DIGOUT1 and generates a separate PTT output for HF, 6m and non-Elecraft transverters that use the low power outputs from the KXV3. It also provided a switched 12v to control the 6m preamp since DIGOUT1 is used on this board. The board contains 6 RCA jacks, one is 12v in from the 12v jack on the K3 rear panel and another RCA is provided with 12v out. There is a switched 12v jack that is activated on 6m for the remote preamp and then the 3 PTT output for HF, 6m and VHF transverters. This is not in competition with the KRC2 which does band decode and lots of other cool stuff, this is a quick and easy way to control amps and transverters. It is NOT for folks running QSK as the relays are typically 35ms switching. I will have some pictures up on the K8GP website tonight. I have about $30 in parts and will provide the units assembled and tested. You will have to provide a interface cable with a DB15HD for the ACC connector on your K3, the other end of this cable connects to this board via a push on connector (supplied) and a suitable enclosure.

Re: [Elecraft] W9OY on P3
That blog seems to be The world revolves around Flex. Beyond the dig on the P3, there was the dig on the Yaesu FT5000. Ho HUM? Now that's the way to judge a radio. I guess we don't have to see a P3 up close to know that the screen doesn't look as good as a 40 monitor. :) The point of the P3 is portabilty, not watching BluRay movies. As for the FT5000, it looks like the best radio Yaesu has come out with for a long time. Using the 9mHz first IF with narrow roofing filters, it will probably be up there with the top receivers in blocking. It also has lots of buttons and knobs for those that want them. If I had lots of money, and there was no K3, I would probably replace the Mark-V with one. The Flex-5000a is a fine radio, other then issues with CW, but I wouldn't want to be married to PowerSDR. I still like knobs, and when PowerSDR-IF is running to use the pandapter, I still spin the knobs on the K3, and avoid that mouse. :) Some hams seem to think the only good radio is the one they have. In reality, there are lots of good radios. Well I have a K3 and it is the best... well I will not go there. :) -- View this message in context: http://n2.nabble.com/W9OY-on-P3-tp4596769p4598590.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] W9OY on P3
To me it is comparing apples and oranges. With the K3 the computer is optional. With the Flex the computer is mandatory. To use the K3 you only need the K3 itself, an antenna, and a key or mike. With the flex you need a bit more. And as has been mentioned before, the K3 will be useable long after Windows xx no longer supports the Flex software and no one wants to update it. I still have a Yaesu FT-101B and FT-101ZD. Both perfectly useable even though about 30 years old. I have confidence that my K3 will still be workable after 30 years. I am less sure about the Flex radios.

[Elecraft] K2 T1 tuner operation question
Hi all, I got my T1 tuner from Elecraft yesterday (bought the built/tested version to speed things up hi) and have a question about operating it. When it's tuning, the K2 power output tends to go bonkers. It often gets up to slightly scary levels while the tuner is still negotiating pretty high SWR's. I've had it at full 15W output at the end of the tune, even tho I started off with the power set at 1W. My question is, is there a way to keep this from happening or at least moderate it a bit? I suspect it's normal for a transmitter's current flow to increase during high SWRs, but I don't want to stress my transmitter any more than necessary. Or perhaps I should just go with the internal ant. tuner - does it do the same thing? Other than that it seems to work great Tnx es 73, LS -- View this message in context: http://n2.nabble.com/K2-T1-tuner-operation-question-tp4598628p4598628.html Sent from the [K2] 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] For you Anti-Scopes
Then listen in SSB mode. If you use the following, it's easy enough to change mode to CW if you hear something interesting: * AUTOMATIC CW VFO OFFSET ON MODE CHANGE: Allows switching quickly between SSB and CW mode without either you or the other station having to re-tune the VFO (often done on 6 meters and transverter bands). First, locate CONFIG:CW WGHT and tap ‘5’ on the keypad until you see “VFO OFS”. From then on, when switching to CW mode from any other mode, the VFO will be offset by an amount equal to your sidetone pitch (as set using the PITCH switch in CW mode). If the sideband most recently used on this band is USB, the VFO will be shifted UP; if it was LSB, the VFO will be shifted DOWN. Note: If you make frequent use of this feature, you may want to use CW reverse on bands where you use USB, and CW normal on bands where you use LSB. This results in perfect pitch matching when listening to a CW signal and switching from SSB to CW. --- On Fri, 2/19/10, Dean45 ebd...@mytargets.com wrote: Although I operate almost entirely in CW my bandpass is typically set wide open. However, this is effectively only about 2 KHz max, which is not nearly wide enough when you want to hear what is going on around you on the band. I concur with this statement. I am used to using my ears as a band scope, and the K3 with the 2 KHz bandwidth limit in the CW mode sometimes makes me feel like I have blinders on. This limit is not present in the Data mode, so it is hard to understand why it is necessary in CW mode. Still a great, versatile radio, but with a curious limitation.

Re: [Elecraft] W9OY on P3
At $400 for a decent PC, including 19-inch monitor (multiple items on BestBuy website, used and new), and $310 for an LP-PAN kit and an EMU-0202 sound card, the choice of a P3 strikes me as having to be based on other than economics. Plus, as Don says, you have the fun of learning the ins and outs of PowerSDR-IF and LP-BRIDGE, both free. Aspirin not included. Monty K2DLJ That's a very interesting observation, Don. I recently got a new computer but I didn't get it to have it bogged down by a CPU hog quite this soon. As well as the cost of the computer you also need to include the cost of the high end sound card. The P3 is looking more cost effective by the minute.

Re: [Elecraft] W9OY on P3
Hear, hear! Julian, I just joined up with MARS - our Military Auxiliary Radio System in the US. One of the objectives I have (now, reinforced by MARS) is to be able to pack up the station and go where needed. Of course this also applies to contesting, mobile ops, emergencies, etc. A standalone rig is vital to the objective above. And not having to do more than plug in cables is equally important, because it seems like set up time may be short. So far, I've been able to tear down the station and set it up after travel in record time. Something less than 30 minutes at each end, neglecting far-end antenna set up time. Simply put, I've never been so pleased with a 10 pound box in my life. That Elecraft slogan, You can take it with you, to me, has become almost everything of importance. [True, this is a recent development...] All of the station fits into a large gym bag, plus a Pelican-like carry case. All of it, even stuff for data modes. It's also important for this type of operation to not have a PC or any similarly complicated piece of equipment get in the way of operating once the station is set up. I've never had to wait long for the K3 to boot up, it's never blue-screened on me, and it doesn't scream at me for security updates. That is a tactical advantage that no PC-based solution could ever provide. I'm not trying to say that Flex (or whatever competition the K3 has) is not a good solution. It may be for a different setting, or the designers had different goals, etc. But if your interests run to portable operation, quick set ups and tear downs, and so on, the K3 is a better choice. Just my thoughts on the subject. I have no financial relationship with Elecraft, except the part where I pay them for new bits on K3 #24. 73, matt W6NIA I found it rather amusing that the bulk of this post, many paragraphs, contained a description of setting up a Flex station for portable use. It involved installing the .Net framework, installing drivers, configuring buffers, recalibrating the radio, installing a virtual audio cable and virtual serial port. Someone using a K3 would probably have got 200 contacts in the log by that point. I don't think it was intentional, but to me he just made the case for why so many of us prefer the Elecraft approach. - Julian, G4ILO __ 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 and the subreceiver
Depends on what kind of operating you do. For some things a second receiver is highly useful, for others, not at all useful. To get the maximum benefit you need a second antenna for each band. Then diversity reception is possible, mitigating QSB and enhancing weak signals. If you like to monitor frequencies you are not transmitting on, especially on another band, the second receiver is excellent. You can do some of this with VFO B, but is limited - see the manual. I have the second receiver but do not use it often. I'm pursuing digital modes right now, not rare DX or weak signals. You can always add the second receiver later.

For exactly the same reasons that we recognise running, cycling, horse riding and motor racing as completely separate events. ... and radiosport has CW, RTTY and phone contests.

The question is why the CW snobs insist that everyone must use low compression, flat head, four cylinder engines and not allow multiple valve, fuel injected and/or turbo charged technology. Every other form of computer assistance - SCP, computer and/or memory keyers, band maps, computer logging, history databases - is all fair game. 30 years ago those were all functions of a second operator but now they're no longer assistance.

Re: [Elecraft] W9OY on P3
Just a minor point: There might be a misconception that high CPU utilization means your computer is inadequate for the task. Actually, you want the CPU to work hard for you. It isn't only CPU you should worry about, it's what is called the 'run queue'. The run queue determines how long your job has to wait until it's serviced by the computer. It's okay to have 100% CPU (and in fact you want it) if you don't have to wait at all. A person assessing the performance of a computer looks at several other things besides CPU when determining what to tune for better performance. Don Wilhelm-4 wrote: I am using a 3.0 GHz Pentium 4 with 1 GB of RAM, running WinXP Pro and the CPU utilization ranges from 50% to 90%, so anyone thinking of choosing this alternative with a lesser computer had better think about a new computer first. __ 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

Quite so, and if I could order one of the new QRP 1500s for what they cost in the US rather than what we'll end up paying over here I'd be tempted to get one just to try it out. Given their list price, the Flex-1500 looks like an interesting alternative to the SDR-IQ as a software panadapter and/or engine for running CW Skimmer. Forget about the QPR transmitter and use the receiver only.

Re: [Elecraft] K2 T1 tuner operation question
If you do not have the internal tuner or the KPA100, the K2's power output indication is just based on an RF voltmeter, which assumes a 50 ohm load. If the load is not 50 ohms, this will be wrong. While the T1 is tuning, the load seen by the K2 will go all over the place. So... Don't worry about it.

[Elecraft] sub RX ant source shared with Main = no RX?
Hello, If I select SUB-RX Ant source Main instead of AUX, it does not rx anyting. When I select AUX it works fine from the AUX. According to the manual The K1 relay should be engaged then sharing the Main ant between the two RXs (latest manual page 42 fig 2). When I change it to Aux it receives fine from that port. K3/100 nr 3636 with KXV3A, no ATU, with latest SW revisions. CONFIG:KR3A is Ant-BNC, changing works vis BSET-ANT. Any ideas, pse? I can't imagine this is a real bug. 73, zoli ha1ag __ 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 and the subreceiver
You probably could, but you would need to rig a QSK system to mute the K2 when the key is pressed. With the sub receiver you tune the DX station with the main receiver and listening with both ears. When you learn that the DX is working split you press the AB button to put both VFOs on the DX, tap SUB to put the sub in the right ear and the main in the left ear. Then tune to the frequency for transmit with VFO A. You can now listen to the transmit frequency to possibly hear other callers or the QSO you are about to QRM or whatever is going on. It only takes a couple of seconds to set up, much less time than it takes to type the procedure. But, if you are short on cash and don't want to buy the sub-receiver, you can just press and hold the AB,3,SPLIT button and work the DX in the normal split manner. I would do this before I would spend the time to set up a second transceiver. (I have a TS-850 setting here, ready to go).

Re: [Elecraft] W9OY on P3
Yes, That thought has occurred to me too. A flex 1500 as second rx with panorama view combined with a K3. Or a RFSPACE IQ for that matter. It's not a new idea. But I think I will settle for something simpler than that. The reason why I bought the K3 instead of a Flex is that I do not like clicking the mouse in everything I do. 73, Arie PA3A = Wait a minute, Joe, are you suggesting an Ele-Flex combination here?

Re: [Elecraft] K2 T1 tuner operation question
LS, Vic gave you good info. If you want a smoother output from the K2 while the tuner is tuning (and the input load impedance is varying wildly), about the only 'solution' I know of is to place an attenuator between the K2 and the tuner - a 5 or 6 dB attenuator with an adequate power rating will do. The attenuator provides a more constant load to the K2 during the process. Unfortunately, you would have to remove the attenuator after tuning - perhaps a relay to switch it in and out. 73, Don W3FPR lstavenhagen wrote: Ok, thanks Vic.

If you HOLD (instead of TAP) RX ANT on the front panel, the Sub RX antenna will toggle between MAIN and AUX (BNC). This is much easier than having to go into the BSET menu IMHO. Of course if you TAP RX ANT, it will toggle the Main RX antenna between ANT1 and RX ANT (BNC). 73, Bill -- View this message in context: http://n2.nabble.com/K3-and-the-subreceiver-tp4593879p4599649.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

I don't want to 'fry' the K2. You need something called a Front End Saver. http://www.aytechnologies.com/TechData/RIP-1.pdf Another alternative to a second receiver is using PowerSDR software with LP-PAN, but this requires additional hardware (KXV3, LP-PAN, decent sound card and a decent computer). You use PowerSDR as your second RX. http://www.telepostinc.com/LP-PAN.html LP-PAN allows you to use your PC / sound card as a second receiver with lots of nice features if you use the PowerSDRTM app. Shown above is split operation using the main and sub receivers in PowerSDR. VFO A (green) from the K3 is linked to the main receiver in PowerSDR, and VFO B (blue) is linked to the sub receiver. The K3 doesn't need the KRX3 2nd receiver option. PowerSDR provides both receivers.

Re: [Elecraft] W9OY on P3
Quite true... Also, with an SDR, just like any other SW based gear, the SW has to work. The hardware is useless if the software is broken. All it takes is one or two hefty bugs to get by their QA and you're screwed. At that point, you have to get the manufacturer a) to reproduce/recognize the bug and b) fix it in a timely manner. If you're fighting a 3rd party issue (i.e. a bug in Windows or some other software an SDR depends on), you're potentially dead in the water with a total loss. These are _big_ challenges to SW customers as we all know. With fully hardware/firmware defined rigs like our elecrafts and others we're not as dependent on that. I.e. elecraft writes the firmware and designs the hardware so they own the whole thing. And 3rd party issues aren't going to be nearly as big of a factor LS W5QD, K2 #6882 -- View this message in context: http://n2.nabble.com/W9OY-on-P3-tp4596769p4600121.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] W9OY on P3
The graphics processor makes a big difference. I have several Dell SX-260 computers that run SDR programs painfully slow, despite 2 GB of RAM and 2.5 GHz CPU. It turns out that Dell's graphic processor has no dedicated memory but rather shares normal RAM. That creates a huge bottleneck when running a graphics intensive program such as all the SDR software. Some is slightly worse than other but they all bog way down on the SX-260 compared with a machine with a separate graphics card and memory. Same SDR program on the SX-260 may run 70% CPU but only 10% on a computer with a separate graphics card and memory, with similar CPU speed and RAM.

Re: [Elecraft] W9OY on P3
Again, you cannot look at *only* CPU utilization and make a judgment about the software, load, etc. Yes, it *could* be a problem, but the point I'm making is you don't know by looking *only* at CPU. It frequently is a symptom of something else happening -- the real bottleneck. For instance, it could be a symptom of running out of memory, but it shows up as CPU because there's a lot of paging going on. To help understand this, imagine you walked into McDonald's. As soon as you put in your lunch order, the people behind the counter start running around like crazy. You get your order in 5 seconds. You go, Wow, that was fast! The next day you walk in and there's 30 people in line ahead of you. The people behind the counter are still working like crazy and each lunch still takes only 5 seconds, but you have to wait a lot longer. The workers are the CPU, the customers are the run queue. We haven't even started to talk about swapping, disk I/O, and other I/O. You might say, Yeah, but if you could hire other workers that worked even faster, then each job might take only 2 seconds. That's true, but in our example it would cut down your wait time from 150 seconds to 60 seconds. That's a great improvement, but chances are the user (you) would still complain about it.

Re: [Elecraft] W9OY on P3
One problem with radios like the Flex hasn't been mentioned much. It is the RF feedback problem. I have seen demos of the Flex in action, and practically every cable in sight had to be loaded down with chokes to keep the RF out of the transceiver control circuits. On the face of it, the P3 in its small metal box adjacent to the K3 should be better isolated against RF feedback. I sure hope Elecraft is checking this aspect closely. There are interconnects between K3 and P3. Are they vulnerable? 73, Oliver W6ODJ On 19 Feb 2010, at 1:46 PM, Jack Smith wrote: The graphics processor makes a big difference.

Re: [Elecraft] W9OY comments about K3
I think some of you guys are really over reacting to the comment made in the link that was referenced. I read the blog and did not even see the K3 mentioned. It did say: Elecraft had their little answer to the pan adapter, what a joke. It was a little screen maybe 9 and made the radio look like a toy. The quality of the display was horrible. He was at Orlando, saw the Elecraft display and made comments based on his opinion. I wonder how many who have responded to the blog posting have not actually seen the P3 in person but yet are ready to defend it to the death? At this point, the P3 has not passed the acid test it will be put through by all of the fanatics on this list. The jury is still out. Based on my having owned a Flex 5000 for a few months at the same time I owned a K3, I can say that the 5000 is a fine radio. I doubt if many could hear a difference between the two. I can also say that it was not difficult to set the 5000 up with the Power SDR software. It worked very well. I actually had a bit more difficulty getting the LP-Pan setup running on with the K3. With both of these, I liked the large panadaptor display on the 22 monitor I have for the shack computer. I don't think I would like a small display like the P3. I think the size will impact the functionality. You may be able to zoom to smaller BW segments on it, but I don't think the small size would work for me. With the guesstimated price of around $700, I'm not interested at all. I'd go back the the LP-Pan solution before I would lay out that kind of money for a P3. With that said, I did not keep either my LP-Pan or Flex 5000 setup. My first radio back in 1966 had knobs and controls on the front panel and so does my K3 in 2010. As far as I'm concerned, it's not a radio if you can't spin a knob..just my own opinion and preference. As a side note, I did find that even with the panadaptor display and the ability to click on a signal to tune the radio to that frequency, you still had to fine tune it with the mouse or other means. That just wasn't for me. It was cool to see the signals across the BW of the display, but you can only work one at a time. I hope those of you who purchase a P3 enjoy it and find it useful. 73, Dave N8AG K2 K3 #414 __ 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] W9OY on P3
Hi All, I have a degree in computer science and 25 years in the industry, and *I* wish someone could explain the disparity in performance among PC makes and models. Hi Hi The fact is there are a very large number of factors that come into play. I can list some here... CPU -- 1 or 2? Video card -- on board processing? The same video board can display vastly different performance depending on OS and driver. There is also differences between models within the same line. Memory -- not just how much you have, but how much is actually available for allocation to the apps. Disk -- when you get to a point where the OS has to page memory out to to disk, the speed of the disk will make a huge difference in performance. Granted you are already compromised in performance at this point, but a faster disk will minimize the pain. Sometimes by an order of magnitude. Drivers -- version and vendor make a big difference here. Some drivers perform well. Others are junk. Hard to know which is which. Junk Software -- many vendors load up the PC with pure garbage that suck up resources and provide little benefit. Sadly you don't always know that this stuff is running or what it's doing. Background processes -- antivirus, malware scanners, file indexing, etc. could impact performance in non-intuitive ways. I doubt I've even scratched the surface here, but I think we begin to see that the combinations of factors at play here makes for quite a challenge in explaining the disparity among machines. Sometimes an older PC will run things faster because it has less unneeded garbage on it and better drivers. It could also have less bloat (XP is less bloated than Vista, for example). When I get a PC, the first thing I do is wipe the hard drive and load my own clean OS. It's a pain but it mitigates many of the problems here and I have always had better performance afterward. Now I do not just reload the OS from the vendor supplied disks -- that just loads the same junk back on. I reload using a fresh copy purchased off the shelf. Hope that sheds at least a little light on the issue. 73 David. K6DCH.

Hi Don Separate controls for the Monitor would have been nice. ON/OFF and level. Same goes for MIC gain, power and processor. I know that you have limited real estate to play with. What program did you use to do those images? The most sensible layout for a radios front panel that I have seen is the FT5000. Even the smaller FT950 has a well laid out front panel. If the K3 had a front panel like the FT5000 boy would it sell! Maybe the K4-XXX will be such a beast. I would be happy to pay the deposit.

Re: [Elecraft] W9OY on P3
I think there is a lot more important things in there other than 1 or 2 CPU's. Architecture means quite a bit more. How much L1/L2 cache, and caching algorithms. memory bandwidth, video memory bandwidth, which ties in with FSB speeds. Pipelining structures and how well each application performs can vary depending on if its optimized for each pipelining structure. Not to mention that the OS can have more than its fair share of play on how efficiently your applications even make it to the CPU. I see Disk as less of an operation speed bottle neck with the price of RAM today but as bad as Windows can get when its been on a computer for a long time this can play a role. Usually it has more to do with start up and shut down times. When you're in Windows how bloated your registry has become and how many TSR's you've loaded over the years can play to a large bit of difference as well. Thats why often just formatting a computer and reinstalling the same version of windows for people usually makes them feel like they just got a brand new computer.

Last month some might remember that I posted a plea for help in fault finding my K3 RS232 connection. The fault was traced to an open RFC L3 on the KIO3 digital I/O board.

Re: [Elecraft] W9OY comments about K3
Those comments on the blog were over the top in my view. I wouldn't say something like Your blog is a joke. That would be somewhat rude. The fact is, the P3 isn't trying to compete with a 22 monitor. It is a portable and easy solution. I don't think I would drag my desktop, LP-PAN, and Firebox audio interface into the woods, just for that nice 22 HD screen. Even if I did, there would be a power supply issue. Does the P3 do the job? Yes. Is it small and ready to go portable? Yes again. Do I need it for my home station, when I already have an LP-Pan, Firebox, and 22 monitor. NO. Is it the best panadapter solution for working portable with minimum current consumption and interface cables? YES. The P3 is hardly a joke. It is a product with a specific purpose, and it fills a void that nothing else fills. I think I will start a blog that compares watching movies on my Asus netbook's 11 LCD, to my 60 Sony. The netbook is a joke, and the display is horrible. But it does fit in my Jeep, and runs for 9 hours on the internal battery. :) Elecraft will sell a lot of P3 units, not because it is the cheapest or best for a home station, but because it is best for portable. Isn't portable a big factor in all Elecraft products? But don't listen to me, as I have Begali keys. I don't need them, but I sure do like them. :) I think some of you guys are really over reacting to the comment made in the link that was referenced. I read the blog and did not even see the K3 mentioned. It did say: Elecraft had their little answer to the pan adapter, what a joke. It was a little screen maybe 9 and made the radio look like a toy.

[Elecraft] Monster K3
--- Tom wrote: If you want to click a screen display to operate you k3 why not just L-P PAN and PowerSDR? --- I've used the point and click interface with K3 and it was not my cup of tea, I'd just go Flex for that if it seemed important. The function keys at the PC keyboard are programmed to supply dedicated BAND keys, MODES, filter width keys, and keys for NB, NR, Notch, and SCAN - all with a single press. The keys are easier to find and use than accessing the equivalent keys on the K3, or by using the mouse. For example the row of F5 to F8 is single press filter widths and I have big labels with 500 1200 2400, and 4000 on the front of the keys. Then, the graphical inteface uses photographic cues to provide a simpler impression for what is happening at the K3, for example the full time display of the DSP filter width, or the display of AUTO NOTCH and an LED as compared to finding the small NTCH at the lower left corner of the K3 display. So, the idea was less to take K3 point and click, and more to make it seem bigger on the desk and add some precision to the S-meter. It's not for everyone, definately retro.

Re: [Elecraft] K3 Utility and LP-Bridge - Correction
Thanks Larry, By the way, since I already had a Presonus Firebox, I am using it for the interface to the LP-PAN. I did find a mod (100K resistor), while poking around the unit, that lowers the spur about 20db. If you or anyone else has interest, I will try to find the picture I took and give details. The spur is still visible with pre-off and att-on, but with pre-on and att-off, it is below the noise. That said, I haven't recorded into the Firebox, so I don't know if the mod had any negative effect on the audio input. My guess would be no. 73, Bob -- View this message in context: http://n2.nabble.com/K3-Utility-and-LP-Bridge-Correction-tp4598240p4600893.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] W9OY on P3
I agree Bob. The Flex 5K is a nice radio. I had one myself for a brief time. It really comes down to user preference as with all things. Of course you cannot beat the K3's receiver performance so that you cannot dispute. But if someone is so hung up on computers then it is not a bad option for them. The main things I did not like about them were 1. I just don't want to rely on a computer being so vulnerable to problems. If you have a computer problem then you have a radio problem too. With any other radio a computer problem does not induce problems with the radio. 2. Just did not like the UI having to bounce back and forth in a contest situation between the logging program and the radio window. Too cumbersome. 3. While the CW performance was improved it was still nothing close to the K3. 4. Too many child programs you had to run in addition to PWRSDR for it to do certain things. And while they did work, it was just one more ingredient in the pie where something could go wrong.

Re: [Elecraft] W9OY on P3
Yes...caching both type and quantity...front side bus speeds...pipelining...registry bloat... I agree with Brett that all these impact performance and can account for disparity in performance numbers between machines. But you can almost never get a true apples to apples comparison between PCs because even if you are running identical hardware and identical software, or what you would think is identical, there are so many other variables that can directly and sometimes dramatically impact performance it's hard to quantify them all. As for me, if it works I leave it alone.

Re: [Elecraft] K3 and the subreceiver
Note on diversity reception.Way back in early 70ies while using two Drake R4C receivers for contesting, I discovered interesting effect. When using two receivers, L R, going to two ears L R, using different antennas - Beverages and Inv Vee, I would come across situations when I can hear weak station using both ears/RXs, but when switching to individual one, signal would not be there. It looked to me like some kind of noise canceling, perhaps in combination with brain processing.Diversity can be with polarization, angles, directions. Having tracking receivers makes it sooo cool.Recently while operating as TF4X in CQ 160 CW while using K3 and array of Beverages, Rhombics and Arctic King (TF4M.com) this again came very handy in digging out the weak ones.

For some things a second receiver is highly useful, for others, not at all useful. To get the maximum benefit you need a second antenna for each band. Then diversity reception is possible, mitigating QSB and enhancing weak signals. If you like to monitor frequencies you are not transmitting on, especially on another band, the second receiver is excellent. You can do some of this with VFO B, but is limited - see the manual. I have the second receiver but do not use it often. I'm pursuing digital modes right now, not rare DX or weak signals. You can always add the second receiver later. Monty K2DLJ Hello all, I'm considering a K3 and I'm wondering what the benefit of paying the extra money for the subreceiver is. Can any of you elmers enlighten me on why one should put down the extra cash? __ 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 and the subreceiver (fixed)
ooops, sorry about the formatting, here it is again. Note on diversity reception. Way back in early 70ies while using two Drake R4C receivers for contesting, I discovered interesting effect. When using two receivers, L R, going to two ears L R, using different antennas - Beverages and Inv Vee, I would come across situations when I can hear weak station using both ears/RXs, but when switching to individual one, signal would not be there. It looked to me like some kind of noise canceling, perhaps in combination with brain processing. Diversity can be with polarization, angles, directions. Having tracking receivers makes it sooo cool. Recently while operating as TF4X in CQ 160 CW while using K3 and array of Beverages, Rhombics and Arctic King (TF4M.com) this again came very handy in digging out the weak ones. Noise floor there was just at about 0 and it was some experience to hear the world, being on the top of the world. K3 is unique in using two RX diversity reception, especially for serious contesting, and when limited with 13 lbs weight limit in carry on luggage - jus' one honey of the radio. Packaging, modularity, circuit design and performance is leaving just about all of my big boxes in the dust. Congrats and thanks Elecraft!

Re: [Elecraft] W9OY on P3
For what its worth, TSR's (so called Terminate and Stay Resident apps) went away with Windows NT and all subsequent NT-based versions of Windows. There pretty much isn't an analogue in current versions except perhaps services which have a slightly similar intent. The registry is a terrible design, mostly because there's no simple way to access it and clean it up. .NET and DirectX are deals with the devil a little bit too as MS rewrites and obsoletes both of these at a frightening rate. They break backwards compatibility on both pretty much at will and in subtle, hard-to-find ways. This forces you into upgrading to be able to keep your stuff working, a very expensive proposition for a .NET/DirectX development shop. I've found the best fix for Windows was to just replace it with something else. MacOS X (and of course an Intel Mac) is what I use and of course the Linux distributions are coming along pretty good. Most of those problems go away in one shot with these hi hi. Only drag is I couldn't use a Flex rig (unless I got the 5000c). Darn. Good thing I have my K2!
