Re: [Elecraft] [K3] Problem w/front panel switches
Get a roll of 3M super strength moulding tape at your local auto parts or farm store. Comes in a red package. Two different widths. It's a grey double sided sticky tape and leaves no residue if you remove it. It's intended for sticking mouldings onto the sides of cars. I cut a little square of about 3/8 ths inch and put under at least the two front feet on the K line stuff to keep everything from moving. It's good for sticking an outlet strip to the desk, etc. Won't hurt the paint and can be removed by rolling it off with your finger. Do not use too much like a whole strip of it, because it'll take a large force to break a large strip loose from say sticking an outlet strip to a formica desk. A little dot here and there does it.

Re: [Elecraft] KX3: No RX - SWR 25 to 1
Hi Fred, The problem as you have described it does suggest that either 1) The KX3's LO (the synthesiser) is not working, or 2) The LO is working, but its output is not getting to the receiver and transmitter mixers because of a broken connection or a bad solder joint. I do not have any details of the pcb layout to see how the LO is connected to the mixers. It would be a good idea, I believe, to try the experiment which Matt W6NIA suggested. But because the LO might be working and its output is not getting to the mixers, I would do one more thing if you do not hear the LO on your main receiver (Matt's test 4). I would use a Sniffer connected to the input of your main receiver to see if the LO is working or not. In case you are not familiar with Sniffers, a useful Sniffer can be made from a loop of insulated wire (not enamel) about 3 cms long, one end connected to the centre conductor of small coax, the other end to the coax's braid. It is wise to insulate the connections. In this case the other end of the coax is connected to your main receiver. By placing the Sniffer close to the LO chip, if the LO is working you should hear it at good strength on your main receiver. By placing the Sniffer close to each of the mixers, you should also be able to tell if the LO signal is reaching the mixers or not. Good luck! 73, Geoff LX2AO On August 27, 2012 at 12:50 AM, Fred Carvalho wrote: snip If it was an analog equipment one could say that the local oscillator stop oscillating. snip On August 27, 2012 at 2:43 AM, Matt Zilmer wrote : Hi Fred, To pin this down a bit further, maybe you could try an experiment. 1.

Re: [Elecraft] KX3: No RX - SWR 25 to 1
Geofrey and Matt I have done what Matt suggested and used an oscilloscope probe at the ouput of the receiver to check for the LO carrier with the RX ISO off. Nothing. So this seems to be the problem However during my tests, the reception went back on for a while. It does this !!! I will try to check for the LO when it returns to make sure I have both situtions checked. BTW I have tried to find a bad connection on the main board by applying some pressure with my fingers, but nothing happens. In case the Rx returns I will check for the carrier with the osciloscope.

Re: [Elecraft] KX3 DVR
Dom, We're working on the DVR feature right now. I'm sorry it has taken so long for us to get to it. At the time we wrote the product brochure, we thought we would have it in place within a couple of months, but many things came up that we didn't anticipate. Every release of the owner's manual includes an errata sheet showing which firmware features have not yet been implemented. The DVR has been on this list since the beginning, along with noise reduction and auto-notch. Since we had literally hundreds of requests to hurry up and finish the NR and auto-notch features, we prioritized those ahead of the DVR. (Until recently there had been very few requests for status on the DVR.) Of course the NR and auto-notch are now complete, so our DSP engineer and I are now digging into the DVR. It's quite a complex feature so I suspect it will take us until the end of September. As soon as we get it fully implemented, we'll be asking for some customers to help test it. I'll be happy to put you on this list if you'd like. 73, Wayne N6KR __ 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] Mac K3 and P3 Utilities
Hi Jim, My apologies if I came across as chastising. It certainly was not my intent. It's just that in my experience, repairing permissions has not solved the problem. It is *usually* not related to permissions at all. If you do get a crash that is solved by repairing permissions, and it happens often, then something serious is going on with your hard drive. I can't remember the last time I had to repair permissions for any reason, and I've been using Macs for as long as there has been Macs. Repairing permissions has become increasingly less necessary since Panther (10.3) was released. The problem with the Elecraft Utilities usually occurs when the firmware folder's name has been changed, or it has been deleted, since the last time the Utility was ran. This can happen, for example, when someone creates a temporary firmware folder to store the beta firmware for download. Once the beta firmware has been loaded, the user no longer needs this temporary folder and will delete it. Then when the Utility runs again, it looks for that deleted folder and when it can't find it, it causes a crash. There are also other situations that can cause problems, such as not having the Help folder in the same location as the app file. There will be new Cocoa versions of all the Utilities released soon that will address this problem. A new version of the KX3 Utility, which addresses these problems, has already been released. Again, I didn't mean to step on any toes.

[Elecraft] K3: interfacing with AL-811 amp and buffering...
Hi All, I would value some advice. Is it necessary to use a keying buffer between my K3 and my old AL-811, or is the K3 keying circuit robust enough not to need this interfacing arrangement? I currently have an ARB 704 buffer in the keying line, but I'm simplifying my shack wiring and wonder if it's safe to get rid of it. Somewhere in the past, I read of keying line transients and the like and what they could do to sensitive transceivers, but I wonder if that concern is valid in the case of the K3 / AL811 combination.

Re: [Elecraft] Win 7 K3 and P3 Utilities
I'm not familiar with the source code, but the obvious common element of I.E. and the Utility is that they both access the internet. I'd suspect some of the shared program files used by both for that purpose and begin with reinstalling I.E. In my work I need to look at HTML as displayed in the various popular browsers, so I have Chrome, Firefox and I.E. all running on my workstation. Every once in a while an update to one of them will cause trouble to that browser or others that triggers those messages.

Re: [Elecraft] K3: interfacing with AL-811 amp and buffering...
John, I am not going to give you a specific yes or no answer, but will give you and everyone else an answer that will tell you how to check any amplifier to see if the K3 will key it without harm. All you need is your amp and a DMM capable of measuring voltage and up to about 10 amps of current. The K3 KEYOUT is rated for +200 volts at 5 Amps. Turn you amp on and connect it to a dummy load (just for safety to the amp). Put the positive lead of your DMM into the center connector of the KEYIN commector for the amplifier and the negative lead to the shell or chassis. Is the voltage DC positive and less than 200 volts? If so, the voltage rating is OK. If it is AC or is negative, then you will need a buffer of some sort. Next, change your DMM (disconnect one lead from the amp first) to measure current - I suggest using the 10 AMP scale (usually you have to change the plug on a DMM lead) - again connect the DMM lead you disconnected from the amp - the amp should go into transmit mode - read the current indicated on your DMM. Is it less than 5 amperes? If both those tests pass with Yes answers, then the K3 KEYOUT can handle that amplifier. All that says nothing about the speed of the amplifier relay. If that AL-811 has the original open frame relay, it will not keep up with the K3 QSK without 'hot switching' which will burn relay contacts and possibly damage the amp's output tank. Plan to use PTT or install a QSK kit in the amplifier. 73, Don W3FPR On 8/27/2012 6:32 PM, zen...@netspace.net.au wrote: Hi All, I would value some advice.

Re: [Elecraft] Mac K3 and P3 Utilities
David, No problem. I was attempting a bit of humor. I kept looking for the preferences after your posts the other day, but just today found your reply on another QA forum. Deleted the preferences files and everything came alive. It is strange that it occurs as often as it does. I have had the utility run for days and then unexpectedly up jumps the devil. I remember an app I wrote for a Forestry group a few years ago. Worked great and all of the sudden one day, it just started having trouble. That turned out to be a memory leak, from an object I did not release. The usage had gone up and crossed a threshold. Embarrassing but true. Actually I was discussing the repair permissions with Apple Care today and it is supposedly on effective on the OS and apps from Apple. So now I wonder how it worked for me. Must have done something. Who knows? As far as folder name changes, none here. and as far as I know the help is always in its default location. I am running the Beta release but I have a folder where I put that stuff and it is there all the time. I have always said, there comes a time in software development when we programmers can hear a click. Everything falls into place. It may take a while sometimes but it will come. Programming is a science , Yes, but it is also an art form. Believe me you have not stepped on any toes where I am concerned.

It's just that in my experience, repairing permissions has not solved the problem. It is *usually* not related to permissions at all. If you do get a crash that is solved by repairing permissions, and it happens often, then something serious is going on with your hard drive. I can't remember the last time I had to repair permissions for any reason, and I've been using Macs for as long as there has been Macs. Repairing permissions has become increasingly less necessary since Panther (10.3) was released. The problem with the Elecraft Utilities usually occurs when the firmware folder's name has been changed, or it has been deleted, since the last time the Utility was ran. This can happen, for example, when someone creates a temporary firmware folder to store the beta firmware for download. Once the beta firmware has been loaded, the user no longer needs this temporary folder and will delete it. Then when the Utility runs again, it looks for that deleted folder and when it can't find it, it causes a crash. There are also other situations that can cause problems, such as not having the Help folder in the same location as the app file. There will be new Cocoa versions of all the Utilities released soon that will address this problem. A new version of the KX3 Utility, which addresses these problems, has already been released. Again, I didn't mean to step on any toes.

Re: [Elecraft] KX-1 power output varies
It is also worth noting that the power output of the KX1 is quite sensitive to DC voltage in. If you can give it 12v the power output should be closer to 3 to 4 watts. It is much more sensitive to this than my K1.

At various times I notice anywhere from about 1.9 to 3 watts power output. In all cases, the ATU has indicated a low SWR after tuning. I'm wondering why the power output varies so much. Is this due to varying losses in the tuner as the match varies at different locations?

Re: [Elecraft] KX-1 power output varies
Michael, The KX1 does not have a power control loop as the K1 (or K2, K3, KX3) have, so its power output is highly dependent on the voltage. Those with power control loops measure the output power and report it to the MCU which will adjust the drive to attempt to produce the requested power. If the voltage is low, it will just take more current to produce the requested power output. The KX3 is a bit different in that it switches output impedances at lower voltages (and reduces the power) to remain more efficient. 73, Don W3FPR On 8/27/2012 8:19 PM, Michael Babineau wrote: It is also worth noting that the power output of the KX1 is quite sensitive to DC voltage in.

Re: [Elecraft] Win 7 K3 and P3 Utilities
I have a propensity to not believe such automated messages as MS is looking for a solution. If it is a problem with an MS application (office for example), that may be believable, but for every other application in the world stretches my imagination. I run Windows XP, and it had finally stopped attempting to (unsuccessfully) upgrade one of the MS DotNetFix solutions on all my computers.

[Elecraft] K-1 4-bander suggestions?
I was out of Ham Radio since the late 1960's getting my license back as an extra class guy one of the last to get the extra when you still had to pass with the 20 wpm test about 10-15 years ago, although frankly I would have made the test alot more difficult as I can remember sitting before the FCC examiner when I was 14 years old in 1966 shaking in my boots taking the novice test. I just ordered a K1-4 bander that should be here by the end of this week. My question is this. Those of you in the know on this group, can you please give me your input as to what additional items that I might want to order from Elecraft for this radio?

[Elecraft] K3 interfacing with AL-811 amp and buffering...
Don - Thanks - that 's exactly what I needed to know. I've measured an open circuit voltage of 16.2VDC at the amp keying RCA jack and current of 116mA when the relay is closed. These parameters are well below the limits of the K3 keying circuit, so I'll remove the buffer interface unit. I see from the AL-811 schematic that there is a 1N4007 across the relay, which is there to block any back EMF pulses from being applied to the keying line, I guess. That was my other concern, whether these transients would damage the K3, but I guess the amp designer put the diode there for that. I'm only using this amp for SSB phone, so QSK is not needed. My amp is nearly 25 years old ( 3 owners now) - it has the original open frame relay: slow and noisy, but still reliable. What I'd REALLY love, of course, is a KPA 500 :) But this old AL811 is humming away perfectly on a set of 572b tubes and I don't have the heart to get rid of it until something expensive goes wrong. I'm off to rationalise my shack wiring - one less black box! 73, John VK7JB __ 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] K-1 4-bander suggestions?
Welcome back! I remember my HW-16 fondly, and I came back to the hobby after a multi-year hiatus as well. I also remember that CW test at the FCC office as a teenager. I would only suggest that you take your time and really savor the build. There are a number of accessories available, but you can order them as you find the need. Try your new radio, engage with the community and get opinions. There are a lot of friendly and extremely knowledgeable folks on the Elecraft reflector. I started my Elecraft experience with a couple of mini-modules to get my soldering skills honed again, then I built a KX1. Then a K2, then a K3, then... I ended up selling off my other gear and now use most of the Elecraft product line. Now I work for them. I sold my first K2 and my second K2 kit is waiting for when I find a few hours free for a few days in a row. 73 de Dick, K6KR On Aug 27, 2012, at 5:49 PM, Jim Hahn jimh...@rocketmail.com wrote: I was out of Ham Radio since the late 1960's getting my license back as an extra class guy one of the last to get the extra when you still had to pass with the 20 wpm test about 10-15 years ago, although frankly I would have made the test alot more difficult as I can remember sitting before the FCC examiner when I was 14 years old in 1966 shaking in my boots taking the novice test.

Welcome to the Elecraft list, Jim. I didn't realize that Novice exams were ever given at an FCC office, nor Technician exams either, unless the examiner gave a person credit for 5 wpm after a 13 wpm test failure, as sometimes occurred (as it did for me in 1969). I just ordered a K1-4 bander that should be here by the end of this week. My question is this. Those of you in the know on this group, can you please give me your input as to what additional items that I might want to order from Elecraft for this radio? I have found the following very useful, in order of importance: 1. Optional LCD backlight - Don't even think of building a K1 without this option!! This is an extremely useful feature that is dirt simple to install as part of the **initial** build of the K1 front panel board, but a real pain in the butt to back fit afterwards. This is truly an important option. (K1BKLTKT LCD Mod Kit) 2. Auto antenna tuner - It has 10 relays that switch its four inductors and five capacitors to produce an inductance range from 0 to 4.9 uH and a capacitance range from 0 to 300 pF in 2^10 (1024) various combinations, of which 1020 are unique. The tuning is a series inductor, with capacitance on either the transmitter side or the antenna side. (KAT1) 3. Noise Blanker - It does a good job on certain types of noise on its minimal setting (HIGH threshold), but can affect dynamic range significantly on the maximum (LOW threshold) setting. (KNB1) I did not find the internal battery option to be useful...no way to charge, a potential source of corrosion if leakage occurs, only eight AA-cells utilized. Also, the standard speaker sounds much better than the micro speaker used with the internal battery kit. (KBT1) I find the tilt stand to be way over-engineered when all I need is something that props up the front of the K1. (KTS1) I would recommend choosing 40, 30, 20, and 15 meters for your KFL1-4 filter board. The 17m band is nice, but it does not compare with the usefulness of 15m. That's one of the finest QRP bands as Solar Cycle 24 progresses. I also have found the 150 kHz VFO span option (you'll actually get about 170 kHz) to be very manageable, at close to 17 kHz per turn of the VFO knob. But some home-made felt washers between the front panel and the back of the VFO knob can prevent disturbing the dial as you remove your fingers from the dial. The 10-turn potentiometer has almost no resistance to rotation and is easily disturbed. I also believe that four small squares of foam tape should be stuck to the four corners of the front panel board, on the side with the MPU socket. This will prevent (1) Audible rattle/vibration at some audio frequencies when the internal speaker is in use, and (2) Visible front panel push button recession when one is depressed, due to play between the corners of the front panel PCB and the support blocks behind them. The K1 is a mature product that appeared in 2000. I built S/N 175 and it has always been my favorite QRP rig. I know of very little else, such as any electrical mods, which should be added. I am remembering the Heathkits of the 1960's which made me nostalgic for a CW only radio. I love listening to 15m when it is open, at 0400, hearing VK, JA, and ZL stations here in Alabama on 15 feet of hookup wire indoors. It's a great portable or backpack rig too. I think you'll like it! 73, Mike / KK5F __ 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
