[Elecraft] Getting ready to order a K2 - which options
Hello Bill, I still carry the view that the rework eliminator is not necessary. Elecraft's instruction in how to upgrade earlier K2 is well written: http://www.elecraft.com/order_form_parts.htm#K2 Parts If you have any problems, please send your email to supp...@elecraft.com Your questions will be well handled by elecraft.

It sounds interesting but I can't imagine that working on K2 upgrades is that daunting, is it? Granted, I didn't build my used K2 but all I've heard is that the process is very straightforward with Elecraft's excellent instructions. I'm about to upgrade my early model to the latest version myself, and was going to just plow through the stages one by one (I already have all the upgrade parts). Would there be any advantage to this rework eliminator at this stage or is that designed for upgrades "to be done at a later date"?

[Elecraft] [PSSVGA] Betta software messed up the K3
After installing P3 SVGA module everything was fine. Then I decided to try the beta software for P3. I had trouble loading it, the P3 utility would show that one of the FPGA images will not load. After couple attempts suddenly MCU LD appeared on K3 display and the red TX LED on K3 would blink. No matter what I do the K3 is stuck in this state and P3 is not working either. When I try loading the software again to P3 it only downloads the MCU and do not recognize the SVGA at all. What did I do wrong and how can I correct the situation? Did anybody have similar problem?

[Elecraft] Getting ready to order a K2 - which options
Completely on the contrary, I always don't feel the "Rework Eliminiator" is necessary. Installation or rework of most of the K2 options is NO more difficult than the K2 itself's construction. Taking KSB2 or , KAF2 and KNB2 as examples, after you take out option, you could easily revert to basic K2 by adding a few jumpers or one / two components. In the construction of over ten K2 in the past, I never felt the need of the rework eliminiator. Currently, I am working on turning an early version K2 into latest version.

Why you may ask - well, the change of the C71 value modifies the PLL voltage range drastically. With the K60XV installed, the lowest voltage which must be adjusted for occurs at 5300 kHz, and if one does not have the K60XV in place, the K2 will not tune to the 60 meter band - so you have to guess about the low voltage point, and remember to revisit it when you do put the K60XV option in. It might be OK to install the headers, add the coax on the bottom of the board and install D19 and D20, but do not change C71 until it is time to install the K60XV. I just worked on a K2 that was sent in for repair because the owner did not know to turn the D19 menu parameter to "y" - the rework eliminators had been installed and he did not know that either (he had just bought the K2).

So, if you have time this weekend, and want to take part in a nice and easygoing operating event/contest, fire up your rigs and jump in! All info is at: http://fists.org/operating.html#feetwet There is a multiplier for each station licensed between 2007 and 2012 that you work. (there is a misprint on the log summary sheet from the website) Hope to hear more people taking part when I go back on perhaps later this evening and throughout the day tomorrow.

Re: [Elecraft] KX3 Power Supply
Why not use the power supp;y that powers the rest of the shack equipment Nrmally in the hamshack environment the footprint is not important - put the power supply under the desk and it does not take up extra desk space. Most of the battery/power supply discussions here has been about portable operation. For Fixed operation, many more possibilities arise such as the Astron linear supplies. I use a 35 amp to power everything in the shack, but you might get away with a 20 or 25 amp supply for a 100 watt station. If you are dedicated QRP, then a 6 amp power supply will be adequate. 73, Don W3FPR On 9/14/2012 8:40 PM, TG9AJR wrote: > Hi, > > I will like to get a small footprint power supply for my KX3 when in fix > operation. > > Any suggestions ? > > Thank you, 73 DX de > > Juan > TG9AJR > > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

I was able to make a simplex contact on the calling frequency and now I am trying to get the offsets set up for repeater. I am looking at both the Fred Cady, the K3 2m transverter manual and the K3 manual and I cannot seem to find the section that talks about frequency specific offset setting for repeaters. Any help would be awesome! If someone has a program in the San Diego area they could send me I would appreciate it.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
The thing is Jim, if you are being relevant or not irrelevant, it is not necessarily the same thing. Certain eyes find that you are not in agreement , using a same meaning response and will accuse you of not being able to read properly, because you have used a negative inverse of another's word meaning agreement. Rather than waste DXcluster space and set of alarms unnecessarily, or not necessarily. why not confront the dirty keyclicker click to click & face to face n let em have it rather than waste Cluster bandwidth.

For the purposes we are discussing here, the only requirement is to show that a signal is notably worse than others of similar strength nearby. A SVGA waterfall display with a good amplitude-sensitive color palette and faster scrolling can show up these defects very clearly indeed. Those features are standard in most PC-based SDR software, but have not yet been implemented in the P3SVGA firmware. The other requirement, as already noted, is to capture the image quickly and easily from the P3SVGA for future use. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek __ 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´m not talking about modulating anything. I know for a fact that transmitters can be keyed without producing key clicks that can be detected in a receiver using 250Hz bandwith with steep filters and tuning just outside that passband. Still the keyed CW signal is "hard" enough to be perfectly readable even if it´s weak. Clicks from a K3 can be heard approx 500Hz out from the passband null, in other words it is not click free. Now, the rise/fall time on a K3 is approx 5ms and the CW signal is quite hard (almost ringing) when listening to it. This is just fine from a communication standpoint but the price we pay are "mild key clicks". I have a feeling, if we just could increase the rise/fall to 6 or 7ms the K3 would be click free or more or less click free. IMO it´s a shame we can´t do this. / Jim SM2EKM __ 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] Phase Noise / CW Key Clicks
Unfortunately in this litigious society, "calling out" someone for outrageous behavior like intentionally generating key-clicks or "wide" modulation can leave one exposed to lawsuits for defamation and/or slander. Without automatically generated, objective and unassailable data, I sure would not want to be naming specific "big gun" stations we all know are engaged in the such practices. It's far easier and safer to condemn the practice general that allow the argument to become a personal battle. 73, ...

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
True. As I said in another post, I'd love to see someone write an SDR application that captured and quantified such things, but in the absence of that screenshots from a scrolling spectrum display (waterfall) would help. The problem is that you lose the amplitude information when you use the waterfall that is necessary to establish the time correlation between center frequency and spurious crap. With a normal spectrum analyzer that shows amplitude you can't see the correlation in a screenshot. Maybe it's possible to display a 3D spectrum display! ;) 73, Dave AB7E On 9/14/2012 12:32 PM, Ian White GM3SEK wrote: >> I don't scan the bands >> looking for bad signals because I spend my time contesting instead, but >> I always jot down the callsigns of the really bad signals I find and I >> highlight the worst of them in my 3830 report.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
Key clicks are CW modulation sidebands. Key click management is about having CW sidebands that occupy a reasonable amount of the spectrum, not eliminating them entirely. Eliminating clicks (the sidebands) is easily done - just don't key the signal. But then you can't send CW. 73, Ron AC7AC -Original Message- Be course the K3 is not click free.

For this and many other reasons, it really would help is if we could *quickly* dump high-resolution screen grabs out of the P3SVGA's USB port, onto a memory stick for example. (A simple system-generated filename with a time stamp would be enough to identify the image for consideration later, without interrupting our own operating.) Part of that same signal analysis package would be a much faster waterfall for improved time resolution. These features were kind-of on Alan's list, but they need some momentum. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek __ 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] Operating from a Hotel
I used to operate successfully from many hotels but every year it is becoming noisier. New ballast lighting, more electronics, etc. But there are exceptions. The suggestions with getting wires outside are excellent. Sometimes I try to have the wires outside, attached to a TV line, which goes to a tuner.

Re: [Elecraft] [KPA500] stuck on TX when AUXBUS attached
This is a matter of physics. A driver pulls its output to a power rail, either power or ground. In the case of the drivers used in the K3 for the AUX signals, pullups are used, to the positive rail to provide the pullup function. This means that when the driver is off, its output will be pulled to whatever voltage the power rail is sitting at. When the K3 is powered off, this voltage goes to zero, thus causing devices connected to the driver to see a zero value at their inputs. Thus the KPA sees a 60 meter input, and the key line appears to be active. Note that the Auxbus signal itself is only an output from the KPA, and has a diode block on the input. Thus it is _not_ part of this situation. There is another, potentially bigger problem that occurs when you parallel two devices in this way. When one device is powered, and the other off, the powered device can actually inject power into the "unpowered" device through the IO lines. This will actually power up the device, at least partially. The device is in a dangerous state at this point, with transistor junctions improperly biased and processors running in very strange situations. It is actually possible to blow ICs in this situation. Beyond this, it is sucking power from the other device. This scenario is called "incidental power," and is a major problem in the telco co-processing arena where we specifically design to protect against it from happening. Now, with all this going on, do you _really_ want to parallel the K3 and KX3 control signals to the KPA, or even leave one connected while the other is driving the amplifier? By far the best thing to do is to pull the plug from the K3 when you use the other transceiver, then plug it back in when you use the K3 with the KPA. Why risk damage to any of this precious gear we have invested in?

Re: [Elecraft] K3 Signalink setup - no TX using MixW
Ken, I figure you are trying to use the Line In on the back of the K3 for audio if so, have you changed the jumper in the Signalink to produce line level output (it comes plugged for microphone level) Once you make that change, you should have sufficient audio. Adjust the audio level to produce 4 bars solid on the ALC meter with the 5th bar flickering. those first 4 bars do not indicate ALC at all, they are there to help you adjust the audio. ALC starts with the 5th bar. In other words, the K3 is different - ignore the common advice of no alc indication. Adjust the power output with the power knob, not the audio level. If you do not drive the K3 audio to the proper level, the power will drift. 73, Don W3FPR On 9/14/2012 12:48 PM, Kenneth Hale wrote: > I have been working for about a week on something that should be so simple, > sending digital.

Re: [Elecraft] Getting ready to order a K2 - which options
If you do use the "Rework Eliminators" (or often called "unPCBs") I recommend you do *NOT* install the one for the K60XV - wait until you actually have the K60XV option in hand. Why you may ask - well, the change of the C71 value modifies the PLL voltage range drastically. With the K60XV installed, the lowest voltage which must be adjusted for occurs at 5300 kHz, and if one does not have the K60XV in place, the K2 will not tune to the 60 meter band - so you have to guess about the low voltage point, and remember to revisit it when you do put the K60XV option in. It might be OK to install the headers, add the coax on the bottom of the board and install D19 and D20, but do not change C71 until it is time to install the K60XV. I just worked on a K2 that was sent in for repair because the owner did not know to turn the D19 menu parameter to "y" - the rework eliminators had been installed and he did not know that either (he had just bought the K2). So he endured the cost of repair and shipping just because of a simple menu entry - don' change C71 until you have the K60XV in hand. 73, Don W3FPR On 9/14/2012 12:30 PM, Wayne Conrad wrote: > On 09/14/12 02:19, Fred Smith wrote: >> One thing I would suggest "strongly" is to consult with Don and ask him to >> advise you of the options and the order of installation as some can be done >> during the build.

I guess you don't read the 3830 reports then.

Re: [Elecraft] K3 min. insulation between in band TX & RX?

I can tell you what I do, and I can run two K3s into 1,5kW Titan amps into beams separated by about 180 ft on the same band. Depending on how the antennas are pointed, I can be within 60 kHz one K3 doesn't know the other one is there. For example, when I point the two antennas to the ENE (the east coast of the US), they are at right angles to each other. If I point one antenna at the other, the radio will usually be overloaded, the preamp will turn off, and the attenuator will turn on, but I can often hear strong stations and work them in between transmissions by the other rig. As an example, I might have one antenna pointed east and the other one NNW to work KL7 or UA0. Another important part of the equation is feedline. The long runs to my antennas are mostly Hard line, and all the other coax in the system (including jumpers in the shack) is very high quality RG8 (similar to LMR400) with a robust copper braid plus foil shield. All of the connectors are Amphenol 83-1SPs, all are carefully soldered, and all connections are tightened with a wrench Each year, I'm part of a group that takes our K3s to a remote county for the California QSO Party (coming up in a few weeks). Our setup allows spacing of about 150 ft between two tri-banders, carefully located so that when we point them ENE (about 70 degrees, which gets us the East Coast, EU, and the Caribbean) they have a null to each other. We use our K3s with 600W amps, mostly KPA500s, but also sometimes a Yaesu or a Ten Tec Hercules II. With this setup, we can have a CW station and a SSB station on the same band and work signals down to about the S5-S6 level. To work weaker signals one of the stations has to switch bands. The primary difference, I think, are the feedlines, which are made from coax pooled from several members of the team. Some very good cables and connectors, some not so good, some connectors crimped rather than soldered, some good soldering, some not so good. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

When I change bands, I hit a dit or tap my mic, the KPA reads the frequency, changes bands, and is all set to go by the time I've found someone to TX to. I'm beta-testing a KAT500, and I'm using it in the same manner. With the KAT500, the AMP KEY line is "looped through" the KAT500 -- that is, K3 to KAT500, KAT500 to KPA500. There are two RCA jacks on the KAT500 that make this easy. The only thing I use the AUX bus for is to drive a KRC2 that switches bandpass filters. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

These guys are much closer to EU than to me in CA, so we don't hear their trash. As long as cheaters like this are allowed to continue without public exposure, they will continue. I don't understand why those EU contesters who play by the rules don't expose them. They must make life absolutely miserable for you.

Re: [Elecraft] [KPA500] stuck on TX when AUXBUS attached
*Art The Auxbus cable without the adapter carries the PTT function also so maybe that is also an issue that FW may not be able to change? With the addition of the KAT500 into the K-Line this may become even more difficult as the Auxbus cable will run from the K3 to the KAT500 and then to the KPA500 to enable really tight integration of the K-Line and this may also make a FW option in the KPA500 difficult.

Re: [Elecraft] [KX3] Antenna Tuner Or Not
The advantage of internal ATU is convenience, just press a button and the tuner works. Also no extra battery and no cable. The tuning range of of my KX3 ATU is good but not great. It matches OK (with exceptions) antennas when their total length is close to half wave or more, but not shorter. For example, a dipole of 40ft would not be matched on 40m. Almost a deal breaker for me in portable work. But my ATU may be broken or toroids in KX3 ATU may have lower loss than in other tuners; in some tuners with lossy toroids one can obtain a match without any antenna connected. Also, the tuning range may be deliberately restricted to avoid lossy matches where ATU may self destruct. With external ATU you can have an easy and low-loss balun by wrapping a jumper (say of RG174) around a toroid a few times. I would buy an internal ATU if size and speed of setup are important issues.

Re: [Elecraft] [KPA500] stuck on TX when AUXBUS attached
Uh - oh... Then perhaps what I'm doing is not 'best-practice'. I just leave the K3 connected and --powered on--, and I can drive the KPA500 from another radio and the KPA500 follows it and works perfectly. I even have the PTT connections from both radios paralleled (the other radio is a FLEX-5000A), so the only thing I need to do is change the source of the rf drive to the KPA500. 73, Dale WA8SRA On 9/14/2012 6:39 AM, Jack Brindle wrote: > Yes.

Re: [Elecraft] [KPA500] stuck on TX when AUXBUS attached
Yes. It must be disconnected. The K3 is loading the band and PTT inputs to the KPA, pulling them low. This has two effects - it will cause the KPA to change to 60 meters, and the KPA will transition into transmit. If you wish to use the KPA500 with another transmitter, you will need to first disconnect it from the K3.

There is wisdom here. What Mike is saying is that, even though your auto-tuner may find a match to make the transmitter happy, there may be more efficient ways of coupling your signal to the ether. IR losses (Ohms law) within the tuner can eat up a fair amount of your QRP signal. This loss is higher when the inductor is wound with teeny-tiny wire. This is the case in some of these small internal ATUs. So, bottom line- 1. The internal ATU can make it possible to operate using an antenna that presents a wild reactance that must be cancelled out to make the transmitter "happy". 2. When an antenna system (i.e. feedline plus antenna) requires a fairly large inductance to cancel out capacitive reactance in the system, this inductance can be provided by the nifty little ATU. 3. If the ATU has small diameter conductors creating this inductive reactance, the Ohmic losses in the wire adds up quickly. 4. The smaller the wire used for the inductors, the higher the losses. 5. To maximize your actual radiated signal, optimize your antenna system to require the least inductance to resonate it. 6 alternative to 5 (above), you could build an external ATU with a large roller inductor made from heavy gauge conductor. 7. For most situations, ignore 1-6 above, and just get on the air. 8.

Re: [Elecraft] Getting ready to order a K2 - which options
If this your only base rig I would order the KPA100 that will give you a lot of operating options with the added wattage and still turn down to QRP if you want I do so with mine quit often. The KAT100 is a very nice tuner and tunes high SWR loads I prefer the external enclosure on mine. One thing I would suggest "strongly" is to consult with Don and ask him to advise you of the options and the order of installation as some can be done during the build. Otherwise you will disassemble much of the radio to install some of the options. On the other hand some are easily done after the build is completed at any time.

Yes, the KSB2 will allow you to use digital modes - the K2 also has a 3rd set of filters that can be set up called the RTTY filter set (turn it on or off in the secondary menu). The K160RX adds a receive antenna and the 160 meter band. The K60XV option adds 60 meters and a transverter interface. The KAF2 adds a peaked audio filter that is very nice for CW. The KDSP2 (which goes in the same place as the KAF2 - you can't have both) adds audio DSP to provide brick wall selectivity as well as Noise Reduction. The KNB2 works well with impulse noise (like auto ignition noise) if that is a problem at your location. The KIO2 allows you to control the K2 from a computer or use an automated logger.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
Jim If you look at any major DXpeditions and pay close attention over 80% of all the radios are supplied by manufactures as well as most of the equipment.

Usually it's Elecraft for one major reason weight vs. performance a excellent comparison weight being important shipping costs, air, ship whatever then carrying them to where they are going to be used. Two radios in the same class FTDX-5000MP top notch receiver and performance proven worldwide at 18"x 8 1/2"x19 1/2" and weighting 50# and only 120v then the K3 about 10 3/4'x4'x10' and weighting about 10# and 12v. This in itself is a huge factor in the selection the sheer size of the two and Elecraft does supply radios to most who request them. I personally appealed Elecraft for the support they give to them I'm sure that along with good antenna donors for just two of many that have helped me to add many "new Ones" to my DXCC count and contributed in my decision to go with Elecraft equipment in my shack. I am not 100% Elecraft "ONLY" like some, but they don't have a few things that others offer or that I like so for now only (6) Elecraft items including 3 radios 2 K3/100's a P3/SVGA and a K2. And all of this came about because of a friend who will remain un-named that cost me all this money when I was happy without anything Elecraft(8-) 73 & Good DX, Fred/N0AZZ -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Thursday, September 13, 2012 1:47 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] [K3] Phase Noise / CW Key Clicks On 9/12/2012 9:18 PM, Matt Zilmer wrote: > The main real-world problem is that the K3 is a minority in the > general ham rig population.

Re: [Elecraft] K2 with Z1000B
Only problem I had with it were all software. When it worked and you could never count on that it was great, but if and how long this time is why I sold mine I spent more time working to keep it working than using it. Then went with RF Space SDR-IQ It works every time and gives you another SDR receiver to boot plus very simple 2 wire hookup with equal Panadpters. 73, Fred/N0AZZ -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Paul Freeman Sent: Thursday, September 13, 2012 10:32 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K2 with Z1000B Good morning, I'm interested in operating a K2 with an installed Z1000B buffer amp. along with LP-Pan 2, SDR software, etc. Primary mode of interest -- CW.

[Elecraft] [KPA500] stuck on TX when AUXBUS attached
Tonight I tried to use my KX3 with my KPA500, but when I turn off the K3 that it is attached to via AUXBUS, then put the KPA500 into OPERATE mode, the asterisk comes on and it is in TX, which means that the receiver of the KX3 goes deaf. Is this the way it is supposed to work, or have I messed up a setting? Will I have to remove the AUXBUS cable from the K3--even though the K3 is turned off--whenever I want to use the KPA500 with another rig?
