Re: [Elecraft] new K3 owner
Spend the time to check off all parts against the parts list. Ensures all is there and aquaints you with many similar looking screws (so you don't use the wrong ones). I bought a large Plano plastic parts box (like a fishing tackle box) with many dividers to place the sorted parts. Some items it is best not to remove from packaging until you install them. Also take your time and enjoy the process of building. Rushing usually leads to mistakes. Likewise do not shortcut the instructions. They were written to help you avoid mistakes! Use pencil to check each off as you work (I also check parts shown in diagrams as they are installed). Often the shows up an error before I go too far.

Use a wrist strap as a minimum, but an anti-static mat in addition is highly desirable. The idea is to keep everything within reach at your work area at the same potential. Do *NOT* use a fully conductive work area (like a cookie sheet) - that can be a hazard to your well-being in case there is a short of some kind - sparks and molten metal spewing into the air and onto your body is possible. The anti-static mat and the wrist strap can connect to the ground screw on the plate of an AC receptacle - but make certain the receptacle is properly grounded, you can check with an inexpensive tester that can be found at your DIY or hardware store in the electrical department. Driving a ground stake is totally unnecessary, and can in itself be a hazard if it is not connected to the utility entrance ground stake with a #6 or larger copper wire. As I indicated, the idea is to keep everything at the same potential (even through a high resistance). The wrist strap will have an internal 1 megohm resistor to assure your safety. 2nd, buy yourself a *new* good quality #1 Phillips screwdriver - do not skimp on quality for that item, stripped or partially stripped screwheads can reward you if you ignore this small item. Some will tell you to use a magnetic screwdriver, but I don't like anything magnetic at my workbench - they pick up bits of metallic things and drop them in places where Murphy says they will cause the most damage. Other than that, follow the instructions in the order written - and do an inventory up front. If you do not understand any step, stop and ask, there will be several on this reflector that will try to clarify for you. Have fun with the build, in the end you will have a great transceiver. 73, Don W3FPR On 1/17/2014 4:11 PM, Carl Yaffey wrote: Hi. I've just ordered a K3 kit.

Re: [Elecraft] How do I put KX3 into transmit with JT65-HF
Ariel, Do you have the KX3 set to DATA A mode? Do you have 4 to 5 bars indicated on the ALC meter? Is the KX3 going into transmit? If you are trying to use PTT from the Signalink, do you have the KX3 set to use PTT? VOX is also usable, but you must get enough audio into the KX3 to activate it. You will be using audio tones out of the SignaLink. The KX3 Utility does not use the audio path, so that does not compare. You must have the Signalink set for mic level output. Set the soundcard sliders in the computer to about 2/3 of full scale. Then start out with the mic gain set at a low value and bring it up until you have 4 bars solid on the ALC meter with the 5th bar flashing. Do your adjustments with a dummy load connected so you don't bother your fellow hams. 73, Don W3FPR On 1/18/2014 7:59 AM, Ariel Jacala wrote: I am sure I am missing something simple here I can't get the KX3 into transmit using the software for JT65-HF.

Yes Randy is correct. The Tube dealers LOVE people who tune up with a Brick on the Key. Kills your Tubes much faster. Plus you get a much more accurate tuneup by sending dots than you do with a solid tone. It duplicates your actual transmissions using dots rather than solid tone. Its really easy to do guys.

Re: [Elecraft] How do I generate a Key Down to tune an external 6m amp?
What the man said was that he was going to plug in a bug. A bug AKA semi-automatic key does not make a string of dahs, just automatic dots. The dah position of the finger piece makes dashes manually like a straight key except that you push it side ways instead of down. A proficient operator can change from using the dot motion to the right and the dah motion to the left to using the dah paddle as a straight key without you noticing. This is a great way to QRS to a slow speed for a new operator without changing keys. If you are using paddles and the internal keyer, you plug it in to the paddle jack. The K3 has two jacks instead of the one jack and a switch to turn the keyer on and off. That is what you are missing.

Re: [Elecraft] new K3 owner
Be sure you have good tools!. Buy a new, high quality #1 Phillips Screw Driver and use it. Round up all the Reed and Prince cheap screwdrivers that you bought at the bargain store and preferably throw them away, if not keep them with the punches, that is all they are good for. Buy a static mat, read the instructions and use it. Read the construction manual from front to back. If you don't understand them, read them again and again until you do. If you still don't understand them, get help until you do. Before you do anything read the appropriate part again so you really know what to do. Follow the instructions in the order the manual prescribes and be sure you understand each step. When you need to plug in a part, make sure that you have the right plug and socket then use as much force as required to seat the plug fully. When assembling something, if it will not go, loosen some screws so you can move it a little then be sure to tighten them before you go on. There is no magic formula, just be careful and forget the hi-hi until you are sending Morse. It is easy, but every step is important and must be done correctly.

Re: [Elecraft] KAT500 Signal Isolation between antenna ports
Hi Keith – Take a look at the measured KAT500 isolation numbers in the “Product Reviews” section of my website at www.ad5x.com. The isolation varies based on the ports chosen, and the frequency band. As an example, the isolation on 20 meters has a worst-case value of 36dB between ports 2-3 (when 3 is selected), and a best case value of 65dB between ports 3-1 with port 1 selected. You might want to select the antennas and ports to maximize isolation. As an example, port 1-2 isolation is much worse than port 1-3 isolation. So I put my 6-meter beam on port 2, and my two HF antennas on ports 1 and 3. You can easily hear signals that are very far down from a desired signal. Measurements made in my old telecom days indicated that you can usually hear tones as low as 90dB down! And, of course, if the signal on the unselected antenna is hotter than on the selected antenna, things can sound worse.

[Elecraft] KPA500 Power On

[Elecraft] Remote K3/0 and 2WIRE 3801HGV modem/firewall
Hi, anyone out there successful in punching holes in the 2WIRE firewall for Remote operation? The user interface for browser access seems to me to be lacking. Does anyone have the secret sauce?? The browser interface also wants the application type from a pull down menu. What are the two 11000, 12000 protocols? The 5060 is SIP.

[Elecraft] KPA500 DC
With all of the recent talk of solar, I've made the move away from my trusty Astron power supply. But the KPA500 remains... I did a little searching but couldn't find anything other than a couple of posts from Oct which looked to be about using an inverter to power the KPA but nothing with real results.

Re: [Elecraft] KX3 comparison
I'm sure that a lot of us would like to see the results of that comparison, George. What we do know is that the Argonaut VI has a higher current demand on receive, and is missing some bands. The Argonaut should have a very good receiver, like the Eagle, and excellent break-in CW; a Ten-Tec legend. But an actual A/B comparison would be useful. The human ear can't detect everything that laboratory instruments can. After much wringing of the hands over the missing bands, I realized that I have an Argonaut VI+ so to speak. All I have to do is turn my Eagle down to 5w. :-) 73 de Jim - AD6CW On 1/17/2014 8:10 PM, george fritkin wrote: I have a KX3 and the new Ten Tec Argonaught Vl.

Re: [Elecraft] KPA500 Power On
I don't know much about hooking multiple transceivers to the KPA500 (I only have the K3/KPA500 mix) but it would not surprise me to learn if the problem might be connected with some status check or something that is expected from the K3 if the K3 is indeed connected or maybe had been connected. A complete power cycle would clear that kind of thing. Is the KPA500 really designed to work with multiple inputs even if they are switched? I would be interested in knowing since I also have a KX3. 73, phil, K7PEH On Jan 18, 2014, at 9:25 AM, Jim Bennett w6...@mac.com wrote: I recently got a KX3 and have set up my station such that the KX3 can share the KPA500, KAT500, and several antennas by using a pretty beefy Daiwa 2-position coax switch.

ditto on the high quality screwdrivers... And, replace them every now and then because even high-quality will become worn over the years. You want the flutes to have nice clean sharp edges -- any rounding at all (which is common on poor quality new screwdrivers) will result in stripped screw heads more often.

Re: [Elecraft] new K3 owner --- addendum on kits...
Phil, Yes, those capacitors are getting more and more difficult to read. My solution is a small lighted handheld magnifier. I think it was designed for reading - look in your local drugstore.

Just plain magnification is not enough - the lighting helps immensely 73, Don W3FPR On 1/18/2014 1:07 PM, Phil Hystad wrote: Also, while we are on the kit-building theme I have a problem with small parts such as small capacitors.

Re: [Elecraft] Remote K3/0 and 2WIRE 3801HGV modem/firewall
It's not so much lacking as it is poorly arranged and almost terminally under-documented. 11000 and 12000 will need to be user-defined. You'll find add a new user defined application at the bottom of the Firewall/Applications page. You'll need to define both ports separately, you only need to select UDP and fill in the port. Leave the application as - Call them something like Remote-1 and Remote-2. As you noted, port 5060 is SIP, and there are probably several choices from the known applications that do SIP, but I think it's easier to define Remote-3 with port 5060 and select SIP on the Application Type pull-down. Once you've defined them, you'll need to pick the computer (your RemoteRig device) by name, and then set it up for each of your applications (Remote-1, Remote-2 and Remote-3). DMZplus mode would probably work, but I don't know how hardened the RemoteRig box might be, so I'm reluctant to say go for it. Note: I don't own a RemoteRig, but I am blessed with one of these wonderful 2WIRE devices from U-Verse.

Re: [Elecraft] KPA500 Power On
I think your on the right track with the kat500 being powerex up first. The other thing that can cause this is if you try to use the kpa500 on 27mhz. When field testing, I tried it and the kpa500 does a full fault and requires power down at the rear, then power up to rset. The FW does a nice job of preventing use on illegal sections of the spectrum such as this. MARS frequencies are fine though.

Re: [Elecraft] new K3 owner
If you're REALLY serious about using the right tools, and do any service work on Japanese radios, you might want to buy a set of JIS (Japanese Industrial Standard) screwdrivers. The cross drive is different from the Phillips or Frearson (Reed Prince). Compatible screw heads are usually identifiable by a single depressed dot or an X to one side of the cross slot. This is a screw standard throughout the Asia market and Japanese imports. The driver has a 57° point with a flat tip. 73, Charlie k3ICH - Original Message - From: Phil Hystad phys...@mac.com To: WILLIS COOKE wrco...@yahoo.com Cc: elecraft@mailman.qth.net Sent: Saturday, January 18, 2014 1:02 PM Subject: Re: [Elecraft] new K3 owner ditto on the high quality screwdrivers...

Re: [Elecraft] new K3 owner
Hi Carl. I am a new K3 owner too. Finished my K3 a month ago (SN7819). Assembling the kit is fun. As stated before: Take your time. I used all anti-static and good tools. Used a wrist strap and anti-static mat. The mat and my wrist strap were grounded to the house safety earth. All boards and components are very well indicated and the manuals are clear. Except the Operating manual. This feels a bit minimal. But don't worry. The support from Elecraft is quite okay. QRP-project in Germany, Elecraft's representative in Europe did very well. I also experienced fast response from Elecraft USA too. No problem to make it a proper job. Read, read and re-read the manuals. And when you finally can run the rig, be prepared to have a long and pleasant learning curve. 73, Peter PA2V Date: Sat, 18 Jan 2014 01:07:58 -0900 From: Edward R Cole kl...@acsalaska.net To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] new K3 owner Message-ID: 201401181007.s0ia7whn036...@huffman.acsalaska.net Content-Type: text/plain; charset=us-ascii; format=flowed Spend the time to check off all parts against the parts list.

Use a wrist strap as a minimum, but an anti-static mat in addition is highly desirable. The idea is to keep everything within reach at your work area at the same potential. Do *NOT* use a fully conductive work area (like a cookie sheet) - that can be a hazard to your well-being in case there is a short of some kind - sparks and molten metal spewing into the air and onto your body is possible. The anti-static mat and the wrist strap can connect to the ground screw on the plate of an AC receptacle - but make certain the receptacle is properly grounded, you can check with an inexpensive tester that can be found at your DIY or hardware store in the electrical department. Driving a ground stake is totally unnecessary, and can in itself be a hazard if it is not connected to the utility entrance ground stake with a #6 or larger copper wire. As I indicated, the idea is to keep everything at the same potential (even through a high resistance). The wrist strap will have an internal 1 megohm resistor to assure your safety. 2nd, buy yourself a *new* good quality #1 Phillips screwdriver - do not skimp on quality for that item, stripped or partially stripped screwheads can reward you if you ignore this small item. Some will tell you to use a magnetic screwdriver, but I don't like anything magnetic at my workbench - they pick up bits of metallic things and drop them in places where Murphy says they will cause the most damage.

Re: [Elecraft] KPA500 Power On
Jim, the key question is what version of firmware is in your KPA500. This is viewable in the menu, under the FIRMWARE selection. Also, what is your RADIO selection in the KPA when using it with the KX3? If you do not have the latest firmware, I would advise you to upgrade. There was a bug fix that affected this some time back.

Re: [Elecraft] KPA500 Power On
Other than this occasional hiccup, yes. If you've got Fred's KX3 book, check out pages 146-147, especially figure 9.17 - this is exactly how I've got mine cabled up. Last night was a good example of why I wanted to have this flexibility. I was listening on 160 meter CW with the KX3 and heard W1AW/0 in Nebraska calling CQ. I cranked up the KX3 power to a whopping 12 watts and called him several times. Not so much as a QRZ did I get. I just got a CQ in my face! So, rather than turn on the K3, switch things over and tune in the station with the K3, I simply powered up the KPA500, set the KX3 to 9 watts (170 watts out on the KPA500), called him again and this time got him on the first call. I could have been there a very long time running 12 watts! Of course if I had a great 160 antenna, 12 watts probably would have been OK. But I live in a CCR/HOA neighborhood and have a stealthy Inverted L semi-hidden in the redwood trees that only has about 25-30 feet of vertical run.

Re: [Elecraft] How do I generate a Key Down to tune an external 6m amp?
This seems like a kluge to reduce average power. It would work if you are manually tuning a tube radio with analog meters, where the meters would integrate the pulsed signal. Sort of. It is crazy for digital metering, SWR metering, or an autotuner. In those cases, the instruments are trying to get a measurement with about 10 milliseconds of carrier (one dit at 60 wpm, if I got the math right). Reducing drive power for tuning is a lot better idea, and works for all situations. With the K3 (or KX3), you can use the front-panel TUNE function and even set reduced drive with the TUNE Power Level option. wunder K6WRU On Jan 18, 2014, at 5:23 AM, John K9UWA j...@johnjeanantiqueradio.com wrote: Yes Randy is correct. The Tube dealers LOVE people who tune up with a Brick on the Key. Kills your Tubes much faster. Plus you get a much more accurate tuneup by sending dots than you do with a solid tone. It duplicates your actual transmissions using dots rather than solid tone. Its really easy to do guys. Just set your coffee cup against the paddles making dots and turn the knobs on your amp.

Re: [Elecraft] new K3 owner
Everything Ed said; Check. I used 18 egg, egg cartons to hold parts and cut card stock in strips, labelled them according to small part then taped them in the individual egg holders with those parts in the egg socket. Didn't knock over like cups would have and kept everything separate till the end. No spare parts when I was done. Gary KA1J P.S.; Good choice, the K3! Spend the time to check off all parts against the parts list. Ensures all is there and aquaints you with many similar looking screws (so you don't use the wrong ones). I bought a large Plano plastic parts box (like a fishing tackle box) with many dividers to place the sorted parts. Some items it is best not to remove from packaging until you install them. Also take your time and enjoy the process of building. Rushing usually leads to mistakes. Likewise do not shortcut the instructions. They were written to help you avoid mistakes! Use pencil to check each off as you work (I also check parts shown in diagrams as they are installed). Often the shows up an error before I go too far.

Re: [Elecraft] new K3 owner
Absolutely true. Same for Japanese motorcycles which I repair, JIS is the only screwdriver to use on those screws. As Charlie said, they are ID'd by the dot on the head. Gary KA1J If you're REALLY serious about using the right tools, and do any service work on Japanese radios, you might want to buy a set of JIS (Japanese Industrial Standard) screwdrivers. The cross drive is different from the Phillips or Frearson (Reed Prince). Compatible screw heads are usually identifiable by a single depressed dot or an X to one side of the cross slot. This is a screw standard throughout the Asia market and Japanese imports. The driver has a 57° point with a flat tip. 73, Charlie k3ICH - Original Message - From: Phil Hystad phys...@mac.com To: WILLIS COOKE wrco...@yahoo.com Cc: elecraft@mailman.qth.net Sent: Saturday, January 18, 2014 1:02 PM Subject: Re: [Elecraft] new K3 owner ditto on the high quality screwdrivers...

Re: [Elecraft] new K3 owner
My perception is that the JIS drivers are the best fit for Elecraft screws. I've never gotten a response from Elecraft about their choice of drivers. 73, doug On 18-Jan-14 16:03, Gary Smith wrote: Absolutely true.

The cross drive is different from the Phillips or Frearson (Reed Prince). Compatible screw heads are usually identifiable by a single depressed dot or an X to one side of the cross slot. This is a screw standard throughout the Asia market and Japanese imports.

[Elecraft] KX3 and Argonaught Vl
First, I have no connection with either Ten Tec or Elecraft, except being a customer. Second, I have 2K3s and 1KX3 Third, I have an ORION ll, OMNI Vll, Eagle, Argo Vl Fourth, More other radios than the law allows Fifth, I am an EE, had my own company and did many products with the same DSP (TI) used in most radios Sixth, there is other junk but why bore you All I can say is wow to both radios. Yes the Argo does not have 12 or 60 meters or built in ATU, all of this has been well talked about. The Elecraft has its short comings too. Fell..the KX feels a little fragile to me, while the Argo feels like a real radio. I hate the power on scheme of the KX, Argo has a real on- off knob. The Argo has this multi-function switch to get triple duty from front panel buttons, while the KX has push once, push twice to get various functions from front panel controls. This gives the Argo a cleaner look, but not necessarily easier operation. If you have a K3 you slip into KX operation easily, if you have an Eagle then the Argo is easy. But I would give simplicity of operation to the Argo, but flexibility and options to the KX So how about operation. Well if you come to my QTH, you only will find a couple of O'scopes and signal generators that are old enough to vote. In other words no fancy test gear just on the air testing. I have been in this hobby for many years (over 50) so I have had many radios. They get better and better. These two radios are simply outstanding. Compared to either of my so called high end radios (and high end price) they and more than hold their own. The speaker in the KX has been well discussed so I will leave it alone, but the Argo has a great internal speaker with tons of audio. I do not use headphones so this does matter to me. Also maybe its me, but the KX seems to have slightly more artifacts in the receive audio than the Argo. The KX QRM rejection controls maybe a little more flexible, but the Argo controls are great also and do their job When you read this realize I am mostly on SSB with a little CW and Digital. But if I were to operate Digital my choice would be KX, but for CW I would stick with the Argo Both put out excellent transmit audio, with the KX sounding smoother and the Argo puncher. So where does this leave me. Other than they are QRP radios, they really are quite different. The whole concept (direct conversion versus down mixing) worlds apart, but they both come to the same answer. They are both truly amazing and engineering master pieces. As a EE and a DSP guy I really appreciate what both have done. Which to buy? I will, as an old Prof. of mine would say, leave the proof to the reader Now excuse me, I am going back to play with my toys. This little write-up covers just a tad of my impressions, if any one has questions, please email me Thanks, 73 de George, W6GF PS: No charge for poor grammar and bad spelling.

Re: [Elecraft] KPA500 Died
Due to recent experience, I have to wonder about the KAT500??? Do you have a resonant antenna or a high power dummy load you can go to directly - removing the KAT500 from the antenna circuit? If it works without the tuner in line - then you have likely eliminated the KPA500 as the problem. I did a similar test using a dummy load (Mil-Spec 2 kW) with the KAT500 in line and carried on a QSO while watching all the meters. After about 45 seconds the tuner went nuts and started a retune - with no change in frequency etc. having been made. I did this to eliminate any futher waste of time checking and repairing non-existent antenna problems. For the naysayers: The dummy load does not heat up at that low power. Going directly to a dummy load eliminates everything in the antenna line(s).

Re: [Elecraft] KPA500 Died
Gary; I’m sorry my attempt at humor struck you the wrong way. You would be surprised at how many avid contesters forget that NAQP is one of the few major HF contests where high power is not allowed. From out this way, high power would help a lot, especially from the postage stamp sized lots most of us have… As for the log, if you change your mind and would like to get a head start on the diagnostic process, go ahead and forward the fault table. Having the analysis ahead of time should speed things up for the crew. 73, and try to enjoy the rest of your weekend. We will get your amp going as soon as we can.

Re: [Elecraft] KAT500 Signal Isolation between antenna ports
Hi Phil, Thanks for the info. I read the product review. I will try to find better combination of antenna connection to the ANT1/2/3 ports. Local noise is very strong in my location, sometimes S7 to S9 in worst case. So bigger antenna picks up more noise. When my 14MHz quad is connected to ANT1, the noise from the 14MHz quad goes to TRX on selecting ANT2 or ANT3. If the unselected ports went to ground level, we would have better isolation. 73 de JH3SIF, Keith On 2014/01/19, at 1:23, Phil Debbie Salas dpsa...@tx.rr.com wrote: Hi Keith – Take a look at the measured KAT500 isolation numbers in the “Product Reviews” section of my website at www.ad5x.com.

You might want to select the antennas and ports to maximize isolation. As an example, port 1-2 isolation is much worse than port 1-3 isolation. So I put my 6-meter beam on port 2, and my two HF antennas on ports 1 and 3. You can easily hear signals that are very far down from a desired signal. Measurements made in my old telecom days indicated that you can usually hear tones as low as 90dB down! And, of course, if the signal on the unselected antenna is hotter than on the selected antenna, things can sound worse.

[Elecraft] KSB2 SSB Adapter Problem
Hi everyone! I recently bought a used K2 with the KSB2 SSB adapter. The builder did a very clean, professional building job on both the radio and the KSB2 and I can find nothing wrong with the construction - i.e. no cold solder joints, no shorts, no solder bridges, all circuit paths are as they should be and have been verified several times. The radio works perfectly normal in CW mode, and RX in the SSB modes is fine. So here is my problem - when I key the radio in SSB mode via either the mic jack or the cw jack, I get a brief HI CUR warning and I get 12 watts of carrier which is unaffected by the carrier balance pot. Also, there is virtually SSB TX audio. ONLY SSB mode is affected. I have taken voltage readings as suggested in the KSB2 manual and found (2) voltages to be out of line, both on U2: U2 pin 5 - 5.99v, should be 0.6v U2 Pin 8 - 0.45v, should be 6.0v These are way out. All connections, components, etc. have been verified correct and good so I am thinking that U1 (the PIC) is the problem as it does affect this part of the circuit. I ahve reflowed all solder connactions on the entire board without success. Toroids have been checked for shorting against the crystal cans, no shorts. Q2 on the K2 RF board has been checked for proper installation and is verified good. Again, the symptoms are: constant 12w output with inability to balance carrier. No TX audio on SSB (yes the mic is good and is correctly wired) Hi Cur message. TX cur is set in the menu @ 2.5A so this should not be a problem. Any thoughts are appreciated, thank you! __ 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

Good Evening, It was sunny and mild for most of the week. The loggers are taking advantage of it by clear cutting the eastern side of this mountain. The road is getting a pounding. Both the county and the logging company have been dumping gravel on the road but it gets pushed down faster than they can lay it. I expect them to continue logging this section until summer. Propagation has been decent when the noise levels drop. The sun has been tossing various ions at us making for both better conditions and an auroral hiss in the background. If the moon were not so bright this week I would probably have been able to see the northern lights this far south. I have only seen them once while living here and they were right on the horizon.

I'll bet your measurements were for 50 ohm sources and 50 ohm loads. Real world antennas differ widely from 50 ohms even when they are close to resonance on the bands of interest, and by a lot more when they are resonant on other bands. And if that isn't enough, source and load Z are transformed by transmission lines between the antenna, the device (the KAT), and the load (the RX). We run into exactly the same issues when measuring bandpass filters, a lot of which I published a year or so ago in NCJ. Our measurements look great, we do them very carefully, but hook real antennas and equipment to these networks and the results can be very different. 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
