[Elecraft] Computer connections??
I am trying in vain to get my KX3 connected correctly to the computer with FLDigi I have the serial cable from AC1 to the serial port and the rig appears to interface with software. The frequency changes and I can click transmit and the radio goes into transmit. However, nothing shows on the waterfall and I am not sure anything is actually transmitting. Does anyone have the definitive guide to connecting the rest of the cables?? It looks like the phone and mic cables are where the problem is. I am just using the built in sound card, not PCI based. Could that be it? There is a mic jack and two speaker jacks on the computer. Help would be appreciated!

[Elecraft] Getting ready to order a K2 - which options
I am getting ready to put in an order for a K2 kit. I currently have the KX1, which is my only rig. I want something more substantial at home to sit on the desktop and have fun with. I am definitely getting the SSB option - mainly because I want to do some of the digital modes. I don't want to do the battery or internal tuner at this time (might make good Christmas presents down the line). What other options should I consider and why?

[Elecraft] KX1 + Tuner + Norcal Doublet
I constructed a Norcal Doublet using some speaker wire. It seems to tune up fine on 20 meters using the internal KX1 tuner - but on 40 meters I could not get the SWR under 4. Would a 4:1 balun help with this? Any links on how to build a simple balun using an aircore and not a torroid? Thanks a bunch!

[Elecraft] KX1 Filter Explanation for Dummies
Okay, so now that I am actually using my KX-1, I need some help. I am really a newbie when it comes to this stuff. Can someone please give me an explanation (at a basic level) of how you are actually supposed to use the filter on the KX-1? If I am listening to a signal, and then turn the filter, I seem to lose the signal. Is this because I am not tuned exactly to that signal? Thanks for being patient, someday it will all make sense.

Re: [Elecraft] KX1 Filter Explanation for Dummies
Okay, that is exactly what I was looking for. I might need to revist the manual and the part about setting the sidetone frequency. I can't remember what I did. Thanks! Burke http://N0HYD.com http://n0hyd.com/ On Sat, Jul 11, 2009 at 11:08 PM, Leigh L. Klotz, Jr WA5ZNU le...@wa5znu.org wrote: Burke, There are two issues: 1. When you set the sidetone frequency in the KX1 menus, you are also choosing the offset at which you hear received signals. So if you set it to 600 Hz, you'll be right on frequency with the other station when the signal you hear is a 600 Hz tone. You can match this tone by ear by goign back to the menu to StP or StL (better since it doesn't accidently change StP) and listening for the same pitch, within about 10 Hz. Once you get on the same frequency, turning the filter down to about 1 Khz will cut out most of the QRM and QRN and will give you a pleasant listening experience. If you're off frequency, the received signal will fall outside the filter passband and you'll be treating it as you would a QRM or off-frequency station, and it will be attentuated. 2. If you turn the filter below 1 Khz, and more prominently, below 500 Hz, the center frequency of the filter itself shifts down a bit, so you may need to re-tune slightly to get the signal back to full strength. Unfortunately, if you do this, you'll also be shifting your transmit frequency, so you can use the RIT feature of the KX1 just to shift the received frequency and leave your transmit frequency alone. You probably won't need to do this unless you need to crank the filter way down, as in a contest, or with a very noisy band. So you can safely ignore this for now and use the filter at about 1 Khz until you feel the need to learn more. Does this answer your question, or do you have a different issue that I've misunderstood? Leigh/WA5ZNU KX1 #712 Okay, so now that I am actually using my KX-1, I need some help.

Re: [Elecraft] KX1 ATU - Alignment Test
It's ALL good! I used the milivolt setting on my DMM, and really fine tuned C9 for the null which is really sharp. Now the power meter is reading correctly, and I am good to go. I will be heading to the deck tonight to toss up my end fed antenna, and give it a whirl. My CW is pretty rusty - but if you are listening on 40 near the QRP calling freq - and have patience, I would love to work anyone out there! Don, thanks so much for all your help!

It makes a BIG difference in both the forward and reverse (SWR) power readings. If the KXAT1 does not show decent power out - in ATU CAL mode into a 50 ohm dummy load, then remove the KXAT1 and install the jumper at J7, then using a known accurate external wattmeter, tell us what the power output on the base KX1 is for each band - ideally, power the KX1 from a 13.8 volt power supply - the reference data I have is based on that power supply voltage, and lower voltages will result in lower power outputs. 73, Don W3FPR Burke Jones wrote: I know this is an old thread, but I thought I would revisit it.

Can you verify that you are actually getting 2 watts or more output? If so, please do that. If you actually do have output, make the following measurements during transmit: 1) Cathode of D1 - the voltage will depend on the transmit power 2) P3 pin 5 - the voltage should be about half of the voltage in 1) above (depends on R1 setting) 3) KX1 U1 pin 2 - the voltage should be the same as in 2) above if all connections are solid. If those voltages are as I have indicated, then remove the KX1 board from the enclosure and check the socketed firmware chip. Pin 2 should be properly inserted into the socket, not sticking out to the side or bent under. If all looks good so far, solder a test point lead on the firmware chip itself and bring it out to the end so you can measure the voltage directly on the chip lead after putting the KX1 board back in the enclosure. Make the check again and see if you have the same voltage at the chip lead as you do at the bottom of the socket. If the voltage is the same, you need to install a replacement firmware chip. If you have proper voltage at one point, but not the next, there is a bad connection between those two points. 73, Don W3FPR Burke Jones wrote: Okay, I have assembled the KXAT1 ATU for the KX1.

Re: [Elecraft] Kx1 Z1 Encoder testing
Okay. Here is what happens. I was lucky when I turned it on to check it was having problems because it sometimes works right. The display showed .8 and 0 volts. I would turn it and it would go to 4.89 volts and the display would change to .9 and the voltage would stay at 4.89 until I turned it a bit. Then the display would change to .8 and the voltage would be 0. It would just repeat this over and over everytime I turned z1 a bit. Then it started working and the voltage would be 0 until I turned it and it would go up into the 5 volt range and then back to 0 when I stopped turning it. Does that seem to indicate a z1 that is faulty sometimes?

Another thing I meant to tell you in the las email. Unrelated to z1. I did the resistance checks on page 54. All checks out good except for Q4 Collector. I am getting 9.63k instead of 10k. Is this a problem? If so where should I look.

Measure the voltage from the encoder pins as you slowly rotate the encoder shaft. The outer two pins in the row of 3 are the ones to measure. As you rotate the shaft, the voltage should jump between zero volts and something close to 5 volts. If it does not go to zero, there is a problem with the encoder. If the voltage does not go up to the vicinity of 5 volts, look carefully at RP3 and U1 pins 3 and 4. If that does not reveal a problem, I can give you some resistance checks to make too. 73, Don W3FPR Burke Jones wrote: I am almost done with my KX1. During each test section I have noticed that there seems to be a problem. Sometimes turning Z1 changes the frequency display but sometimes when you turn it the last 2 digits on the display just go back and fourth - like from 1 to 2 then 1 then 2. I have triple checked the solder connections at Z1. I am trying to figure out if I might have a faulty Z1 encoder. Can anyone tell me how I could use my DMM to test directly at the leads of the Z1? If so which leads and what should I look for? Thanks for all your help!!

Re: [Elecraft] KX1 help
Edward, Welcome. I have been a Ham for many years, but I am just getting back into the hobby. I don't have an HF rig, so right now I am building the KX1 just as you, so I thought I might have a couple of thoughts. I am a soldering robot who can follow directions well - but I don't understand a lick of electronics theory! For power, I just went down to the local battery mart and purchased a 12V SLA battery, similar to the ones used for security system backup batteries. Then I just have alligator clips that attach to the batter, a fuse inline, and the J1 plug at the other end. Because I live in an antenna restricted neighborhood, I am opting for the PAR Electronics End-Fedz antenna. It is very discrete and I could easily take it down if needed. Plus it will work when we go camping. They have gotten good reviews and they are priced in my budget. I am currently working on Section 2 of the construction manual. I hope to have this section completed this weekend. It is very fun to build, and so far simple if you follow the directions. As you have seen, the guys on this list are a HUGE help if you run into trouble!!! Let me know if you have any questions.

I am going to add the auto tuner and the optional 80 and 30 meter board later. So as far as a power supply can I use an old AC adapter as long as it is within 8 to 14 VDC and if so how should it be connected to the connector for J1. Or would a commercial type application be a better choice. As far as the antenna is concerned what type of wire should be used and how is connected to the connector. I hope that as I start building my kit that these answers will be a little more obvious but I am trying to get as much information as I can before I start building.

[Elecraft] KX-1 Trouble...
Okay gang...I have finished up part one of the build. I applied power today and all the voltages checked out fine. The LED lit up, the display worked until I hit the menu button and LED appeared on the display. Then I tried turning the VFO knob to cycle through the menus, but it would only sparodically change menus. As I turned the VFO knob, every so often, very random the display would change to another menu item. Something appears to be wrong. I can't see any solder bridges, etc, all parts for Part One are installed. I am a complete electronics newbie, but can follow instructions well. I would love some ideas!

Re: [Elecraft] KX1 Newby Help!
Don, Philip Paul - Thank you guys so much for the help! It turns out I was confusing infinite resistance with zero resistance - it looks like I am good to go ahead with the next step. I have a steady hand and I am good at following the excellent direction provided by Elecraft - so with your occasional help, this project should end successfully! Again, thanks for the clear and patient explanations. Burke Jones N0HYD Olathe, KS On Mon, Dec 22, 2008 at 9:08 PM, Don Wilhelm w3...@embarqmail.com wrote: Burke, What do you mean by nothing? I am going to guess that it means the DMM indicates the same as when you have nothing connected to the leads and the DMM is set to read resistance (correct me if I am wrong). If my assumption (guess) is correct, that is the indication for infinite resistance (i.e. an open circuit) for your DMM. Now - consider the meaning of the indicator. That is the symbol for greater than. Infinite resistance *is* greater than the value indicated, so if my assumption is correct, you have no problem. A DMM resistance reading that continues to climb usually indicates that the DMM current is charging a large capacitor. As long as the lowest reading is greater than that indicated in the manual, no problem exists. Realize that at this point the resistance measurements are checking for shorts.(with the exceptions of the readings that are (less than) 5k), so any measurement that is greater than the indicated value (to include infinite resistance = open circuit) passes the test. 73, Don W3FPR Burke Jones wrote: Okay, I am a complete electronics newby - so please be patient. I have worked my way carefully up to page 26 on my KX1. I have double checked everything, but I may need to do it again. The problem is with the resistance checks.

This is true even if I touch the solder points on the bottom instead of the pin holes or legs. Also when I check the diodes D2 and D3 the Ohms just keep getting higher and higher. In other words when I touch the banded end of the diode the resistance just keeps increasing as long as the probe is on the lead. Is this correct? Any help would be much appreciated! This is my first kit, and while I know basically nothing about electronics I am good a physically constructing things and I am careful in my work.

[Elecraft] Walwart power?
Could I use a 12V 500ma to power my KX1 when at home? Burke Jones N0HYD Sent from my iPhone ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Walwart power?
Thanks guys! You have confirmed my suspicions. Burke Sent from my iPhone On Dec 23, 2008, at 5:23 PM, Don Wilhelm w3...@embarqmail.com wrote: Burke, There are exceptions to everything, but in general, wall warts are not a good power supply choice. For most of the 12 volt wall warts, the no-load voltage soars to as much as 17 volts and when loaded to full rated current, the voltage will sag below 12 volts. Now, if you can find one that is well regulated, it *might* be OK, but it has been a long time since I have seen regulated wall warts advertised. Most wall warts are designed to be used with equipment that contains an internal regulator and filtering. I would suggest looking for a 13.8 volt 3 (to 6) amp power supply. 73, Don W3FPR Burke Jones wrote: Could I use a 12V 500ma to power my KX1 when at home?
