Dave (G0DJA) - Original Message - Sent: Friday, June 27, 2014 9:43 AM Subject: Re: [Elecraft] KX3 - UHF emissions I've just done a couple of tests using an RF Explorer portable spectrum analyser set to monitor between 15MHz and 614MHz. I can 'zoom in' if necessary but kept it wide in the first case to have an overview of as wide a frequency range as possible. The antenna is the Ngoya NA-773 144/430MHz whip antenna supplied with the analyser with the whip fully retracted.The analyser and fitted antenna are about 15cm (6inches) away from the KX3. My KX3 has leads plugged into the RX I/Q socket, the Phones socket, the ACC1 socket and a 13.8V supply to the 9-15V DC socket. No cable connected to the ACC2 socket. None of the leads have any RF beads on them, that I can see anyway. The DC, ACC1 and RX I/Q leads are the ones suplied by Elecraft. If the screenshots get taken off before they get onto the reflector, I'll put them in a dropbox folder and will post a link. The 1st screenshot shows the situation with the KX3 switched off, date stamped 27-06-2014 1002. With the KX3 swiched off I see a steady signal at 389.999MHz (-83dBm) and, as the red line shows, there's an occasional signal at 143.571MHz (-78.5dBm). There's also another occasional signal at 422.142MHz (-78.5dBm). The second screen shot is with the KX3 switched on, date stamped 27-06-2014 1005, frequency set to 7.080Mhz USB. With the KX3 on I am seeing a rise in the noise floor at a whole range of frequencies, but no specific single frequency spike, other than the ones that I see with the KX3 switched off of course, as yet. I'll set the analyser to monitor just the VHF/UHF spectrum next and see if I can track any specific carriers down.

I use those double ferrule aluminum crimp on's that are designed for flexible wire cable to hold everything together. I was concerned about them holding through the poly insulation, but the following antenna has been up for about ten years now. It consists of a double (fan) dipole with a pair of 80 meter traps in the top leg for 160 80 M coverage and a pair of 40 meter traps in the lower leg for 60 40 M coverage. It is fed thru a 1:1 balun with RG-213 and is tuned for resonance. Basically, I operate SSB 99% of the time, so the antenna is tuned for that end of the bands. An MN-2700 tuner in the shack takes care of small excursions from resonance. It's only up about 50 feet, so performance is what you'd expect. It's not straight either and is sort of a lazy Z, being strung between two 55' telephone poles that are 105 feet apart. The ends droop down at about 45 degrees to tie-off points in trees.

In the middle of the cord I attach the balun for the Vees, thereby allowing the legs to be in the clear, moveable from side to side, and tied to smaller (8') trees at their distal ends. In one variation on the theme I had a 40 meter dipole as the center section of the supporting rope, tied to the same balun as an 80 meter vee. In another I tried a linear-loaded 80-meter Vee, about 45' on a leg; it loaded fine but didn't perform as well as the full length version. If you can suspend a flat antenna between two tall trees, why would you want an inverted vee, which is a less effective radiator? Your two trees 200 ft apart could support a full size 80/40 fan and a 20/15/10 fan, in line with each other. A high 80/40 fan is a VERY good antenna, and is easy to build. My technique has evolved to starting with #8 bare copper from the big box store, stretch it VERY slowly between a tree and a trailer hitch until it breaks. Do this carefully where there's no one around to get hurt. Now you have #10 hard drawn copper, which is pretty strong, and pre-stretched. Use that for the longest dipole in each fan. Use #12 or #14 THHN (house wire) for the other elements. I make spacers by cutting 1/2-in PVC conduit into lengths of about 16 in for 3-wire fans, and about 12 inches for 2-wire fans. 5-6 ft between spacers is a good rule of thumb. Hold the spacers in place by soldering short lengths of copper around the spacer to the bare copper of the long element. The higher your antenna is, the more robust your center insulator should be. A high 80/40 dipole (80 ft or more) will be closer to 75 ohms than 50 ohms. A 20/15/10 fan will be close to 50 ohms. Use RG8 or RG11 depending on the Z at resonance. Don't waste a dB or two with small coax. My 110 ft 80/40 fans are fed with Belden 8213. For weights, I fill 6 gallon water jugs with dry sand, and tie one to one end of each span. The other end can be fixed. I have pulleys high my trees. If you don't have a pulley and weight, your antenna WILL end up on the ground, and it won't take a big storm for that to happen. My HF antennas are all at the 110-120 ft level in a dense redwood forest that towers 50-75 ft above them. They work. My seat of the pants observation is that attenuation increases with frequency, and is greatest with vertical polarization. 432 MHz is a waste of time, 2M sort of works, and 6M works pretty well. For an analysis of the value of height, study this. It supports the statement earlier in this thread that a high dipole beats a low tri-bander.

Re: [Elecraft] RF in the Trees
The professional Arborists use a cloth or leather bag filled with lead shot and something called tangle-free line or similar to throw up in a tree so that they can pull up a supporting rope for tree trimming etc. From what I've seen, the bag is about the size of a tear drop shaped golf ball. The idea of the shot instead of a solid weight is to make the bag less damaging if it hits your house (or window) on the way down. I have a neighbor who's son is an arborist, so I've watched him on several occasions. It DOES take a bit of practice, but the line never seems to get tangled. I tried this with a few lead fishing weights on some thin nylon line and it was a disaster. The secret is to use a thick enough line so that it won't spin around itself and (mysteriously) tie itself in a knot way up in the tree. 73, Charlie k3ICH - Original Message - From: Fred Jensen k6...@foothill.net To: elecraft@mailman.qth.net Sent: Thursday, June 26, 2014 8:05 PM Subject: Re: [Elecraft] RF in the Trees On 6/26/2014 4:12 PM, Rick Bates, WA6NHC wrote: This may be off topic, but in light of it being Field Day Weekend in the US It's radio, Eric will probably see it as relevant, unless we overdo it, which we do at times. :-) The arrow has an issue because it gets hung up or in branches and doesn't have enough mass to pass through some branches or allow gravity to pull it down.

I believe Jim K9YC modeled a true vertical dipole (including the n6BT end-loaded vertical dipole) - but I would expect it to work out differently from an end fed half wave vertical. The GAP antennas and Cuschraft R8 and R9 type are supposed to be loaded vertical dipoles, and are not, I don't think, end feds... but that is the question... are these really all equivalent? Certainly feeding at the bottom of an end fed would be easier from a construction and deployment point of view, so I can see the obvious appeal therefor, but then does it work as well as, say, the N6TB vertical dipole fed in the middle?

Half-wave dipoles are equal no matter how they are fed. With an end-fed dipole, the short counterpoise advocated by W8JI is merely a method of accomplishing feed to that high impedance point.

I know W8JI thinks the end fed half wave needs some sort of ground system-counterpoise to keep the feed line from becoming part of the antenna, so I am wondering - asking not telling - whether these two are really equivalent? (He said reaching for his ARRL Antenna Book...) I believe Jim K9YC modeled a true vertical dipole (including the n6BT end-loaded vertical dipole) - but I would expect it to work out differently from an end fed half wave vertical. The GAP antennas and Cuschraft R8 and R9 type are supposed to be loaded vertical dipoles, and are not, I don't think, end feds... but that is the question... are these really all equivalent? Certainly feeding at the bottom of an end fed would be easier from a construction and deployment point of view, so I can see the obvious appeal therefor, but then does it work as well as, say, the N6TB vertical dipole fed in the middle? __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Do we need 2 groups?
Hello, Yahoo has a feature that I use for each of my groups.

I scan the summary and, if any topic looks interesting, I scroll down to read it; otherwise, I delete that email. Some groups may have as many as 15 postings in that summary, so with this feature, rather than having to delete 15 emails, I delete only one. I'd like to have that feature here as well.

Re: [Elecraft] KX3 - UHF emissions
Hi Dave, Thanks for performing this comparison test. I admit that I found it difficult to perform repeatable measurements, as levels varied by as much as 10 to 15dB due to position and orientation of the rig and cables and my position with respect to the equipment. That is why I chose to provide considered representative figures derived from multiple observations as opposed to precise measurements or screen-shots, but I could provide screen-shots by way of examples if anyone feels that would be really useful. My KX3 is #01685, purchased complete (not kit) with the roofing filter and ATU options, from Waters Stanton in the UK. I fitted the battery charger when it shipped, and have also recently fitted the SideKX end-plates and a VE7FMN CoolerKX heatsink (although as noted before, the issue described pre-dates these retrofits). Your results lead me to hope that my KX3 might be defective and that the problem could be resolved by repair or exchange. I suppose I should order a KX3-PCKT cable set to try in case the official I/Q cable mitigates this issue, but I have tried the 2.5mm to 3.5mm stereo cable that came with my Sennheiser headphones and that didn't seem any better. I look forward to hearing confirmation from Elecraft of whether or not these emissions are considered typical for this build standard of KX3. Cheers, 73 Darren, G0HWW On 27/06/14 11:39, Dave wrote: Here are two more screen grabs for KX3 on and off, but just looking at the frequency range 100MHz to 500MHz.

Re: [Elecraft] Adding an SPE amplifier
I have exactly the same setup with Expert 1K-FA, K3 and P3 and have been using it for the last 5 years. I actually have a pair of K3s connected to 1K-FA simultaneously. It is pretty easy to connect SPE amp to your system. You need to make Y splitter for RS 232 port of K3. One leg of Y goes to P3, another goes to one of the DB15 connectors of the amp. The details are in the SPE manual that you can download prior to your purchase. This amp actually got 3 x RS232 ports. 2 ports are on DB15 connectors (these are used for CAT connection of 2 transceivers, PTT, ALC etc) and one port on DB9 connector used for remoting the amplifier where you can duplicate all the buttons and meters on the computer screen with the help of a software SPE supplies with the amp. 73, Igor UA9CDC - Original Message - From: WILLIS COOKE via Elecraft elecraft@mailman.qth.net To: Bill Turner dez...@outlook.com; elecraft...@yahoogroups.com; Elecraft at mailman.qth.net elecraft@mailman.qth.net Sent: Friday, June 27, 2014 11:19 AM Subject: Re: [Elecraft] Adding an SPE amplifier The SPE Expert Amp needs a separate connector to the port.

Re: [Elecraft] Do we need 2 groups?
Jerry, You *can* do that on the Elecraft reflector. Go to http://mailman.qth.net/mailman/listinfo/elecraft, log in, and set your mail delivery to Digest. I find that inconvenient to post a reply, or even to read through it, and some replying to a digest post do not delete the 'extra' and you find the entire digest being sent back to the reflector. You might try what I consider better, just by creating a filter in your email client. First create an Elecraft folder in your Inbox. Then create a filter so that everything with [Elecraft] in the subject line is moved to the Elecraft folder. Now you have your own personal digest that you can view at any time. Delete those emails that are not of interest, reply to those you wish to, or save some for future reference. Quick and easy and it does not clutter your Inbox. 73, Don W3FPR On 6/27/2014 10:48 AM, Jsodus wrote: Hello, Yahoo has a feature that I use for each of my groups.

Re: [Elecraft] Noise from P3
Bill, I do not have the SVGA board in my P3, but do weak signal 6M operating and have no difficulty with noise floor increases on the K3 on 6M. I removed power completely from the P3 just to be sure. The noise floor stayed the same. You might remove the SVGA board and just see if that is the problem. Most modern flat screens actually do not turn fully off with the on/off switch. I would remove the power source completely to make sure the noise is not from the monitor.

Re: [Elecraft] RF in the Trees
On 6/27/2014 6:30 AM, Don Wilhelm wrote: if you can couple RF into it, it will radiate. Yes. There are many ways to feed a vertical dipole. I developed a method that uses the outside of the coax as half of the dipole, and uses a ferrite choke to form the end insulator. The choke is positioned a quarter wave down the coax from the center insulator. I published this method about six years ago, after seeing a similar suggestion ftrom Rudy Severns, N6LF. Rudy used a coil of coax, forming only an inductor. My contribution was the ferrite choke, which makes the antenna insensitive to feedline length. The end of a dipole is a high voltage point, so there's considerable voltage across the choke if you're running much power. I tested this concept around 2008 on 40M with 1.5kW, and found that I needed two chokes in series, each of which was 5,000 ohms. A single choke would work quite well at 100W or less. Note that electrically, this dipole is center fed -- there's a quarter wave wire connected to the coax that goes to an end insulator that can be suspended in a tree, then the coax hangs down, and the choke is a quarter wave down from the wire. The impedance of a vertical dipole like this is about 70 ohms at resonance, which makes it a good match for 75 ohm coax. Remember that SWR in a system is determined by the match between the antenna and the line, so losses will be lower with 75 ohm coax. Also remember that the velocity factor of coax is for signals INSIDE the coax. For signals OUTSIDE the coax, the velocity factor is like any other insulated wire of comparable size, roughly 0.98. The choke should be wound using the guidelines in my Cookbook. 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] RF in the Trees
I don't really understand why traps have gotten such a bad rap. Consider that most all triband beams use traps as well as many verticals. I have been using Spi-Ro traps for 20 years and never had a problem and I certainly don't see any indication that I am suffering some kind of loss as a result. I have made many comparisons between the trapped dipoles and single band non-trapped dipoles and the only difference I see is a reduction in usable bandwidth. The Spi-Ro traps are rated for 600 watts making them perfect for the KPA500 powered station. Indeed - do not rule out traps. I also use a similar wire that to what Charlie mentions. Last order was for 600 feet. It's great stuff. Now I'm thinking of what would be the best all-band antenna for the K2 which is my secondary operating position in the living room where I can give demos to visitors. I'm thinking of giving the 88 foot doublet fed with 300 ohm twinlead a try. Doug -- K0DXV On 6/26/14, 6:30 AM, Charlie T, K3ICH wrote: Don't rule out traps. Also, the RF Connection and probably others, sell a nice stranded copperweld wire that has a black polyethylene insulation. If I remember correctly, it is 13 ga and is ideal for antennas. For all practical purposes, it doesn't stretch, is fairly slippery and only a little springier than hard drawn copper. I use those double ferrule aluminum crimp on's that are designed for flexible wire cable to hold everything together. I was concerned about them holding through the poly insulation, but the following antenna has been up for about ten years now. It consists of a double (fan) dipole with a pair of 80 meter traps in the top leg for 160 80 M coverage and a pair of 40 meter traps in the lower leg for 60 40 M coverage. It is fed thru a 1:1 balun with RG-213 and is tuned for resonance. Basically, I operate SSB 99% of the time, so the antenna is tuned for that end of the bands. An MN-2700 tuner in the shack takes care of small excursions from resonance. It's only up about 50 feet, so performance is what you'd expect. It's not straight either and is sort of a lazy Z, being strung between two 55' telephone poles that are 105 feet apart. The ends droop down at about 45 degrees to tie-off points in trees. A compromise? Yes, but it works. 73, Charlie k3ICH - Original Message - From: Jim Brown j...@audiosystemsgroup.com To: elecraft@mailman.qth.net Sent: Thursday, June 26, 2014 1:55 AM Subject: Re: [Elecraft] RF in the Trees On 6/25/2014 5:43 PM, Dauer, Edward wrote: So, I've been selecting two of the tallest candidates a couple of hundred feet apart and stringing a stout nylon rope between them. In the middle of the cord I attach the balun for the Vees, thereby allowing the legs to be in the clear, moveable from side to side, and tied to smaller (8') trees at their distal ends. In one variation on the theme I had a 40 meter dipole as the center section of the supporting rope, tied to the same balun as an 80 meter vee. In another I tried a linear-loaded 80-meter Vee, about 45' on a leg; it loaded fine but didn't perform as well as the full length version. If you can suspend a flat antenna between two tall trees, why would you want an inverted vee, which is a less effective radiator? Your two trees 200 ft apart could support a full size 80/40 fan and a 20/15/10 fan, in line with each other. A high 80/40 fan is a VERY good antenna, and is easy to build. My technique has evolved to starting with #8 bare copper from the big box store, stretch it VERY slowly between a tree and a trailer hitch until it breaks. Do this carefully where there's no one around to get hurt. Now you have #10 hard drawn copper, which is pretty strong, and pre-stretched. Use that for the longest dipole in each fan. Use #12 or #14 THHN (house wire) for the other elements. I make spacers by cutting 1/2-in PVC conduit into lengths of about 16 in for 3-wire fans, and about 12 inches for 2-wire fans. 5-6 ft between spacers is a good rule of thumb. Hold the spacers in place by soldering short lengths of copper around the spacer to the bare copper of the long element. The higher your antenna is, the more robust your center insulator should be. A high 80/40 dipole (80 ft or more) will be closer to 75 ohms than 50 ohms. A 20/15/10 fan will be close to 50 ohms. Use RG8 or RG11 depending on the Z at resonance. Don't waste a dB or two with small coax. My 110 ft 80/40 fans are fed with Belden 8213. For weights, I fill 6 gallon water jugs with dry sand, and tie one to one end of each span. The other end can be fixed. I have pulleys high my trees. If you don't have a pulley and weight, your antenna WILL end up on the ground, and it won't take a big storm for that to happen. My HF antennas are all at the 110-120 ft level in a dense redwood forest that towers 50-75 ft above them. They work. My seat of the pants observation is that attenuation increases

Re: [Elecraft] RF in the Trees
Doug - I've been using an 88 foot long doublet at 45 feet for about four years - works very, very well on 40-6 meters. It tunes on 80 but I have an inverted L I use there. Currently I feed it with about 110 feet of 450-ohm ladder line and a Current Designs 4:1 balun, and then about ten feet of RG-8X into the shack. My only complaint is that the SWR jumps all over the place when it's raining, which it normally does here in this part of the state in the winter. I may go back to 600-ohm open wire line later this summer. But other than that, the 88-foot doublet is a good performer. BTW - mine is made out of #26 silky coat wire from The Wireman in SC - I have to keep it stealthy, but have no problem running 500w to it from my Elecraft K3/KPA500.

[Elecraft] KX3 FAST-PLAY field-test firmware now available (rev. 2.11)
Several KX3 users have now tested the new fast-play feature (see operating details below), so we're making the firmware available for those who don't mind working with a field-test release. It'll be a great feature for Field Day, but you'll want to get it downloaded and tested before hand. The rev. 2.11 firmware can be found on this page: ftp://ftp.elecraft.com/KX3/firmware/beta/ (If it's a bit slow, note that FTP directories can take awhile to open.) Make sure you have the latest release of KX3 Utility before loading the new firmware into your KX3. If you haven't loaded new KX3 firmware in awhile, you might have a temporary issue with MCU/DSP firmware compatibility that affects the load process. If have any difficulty with the normal one-click firmware load: 1. Select Advanced mode within KX3 Utility. 2. Check the box to load just the MCU code, then click the send button. 3. When the MCU load completes (possibly with DSP error code), check the box to load just the DSP code, and click send. On completion of Here are the details on fast-play: FAST MESSAGE PLAY A long-hold of MSG (~3 sec) puts the KX3 into FAST PLAY mode. In this mode, the BAND+, BAND-, and FREQ_ENT switches can be used to play/repeat messages 1, 2, and 3 immediately, without the need to first tap MSG. To turn off fast play, hold MSG for ~3 seconds again, or turn the KX3 off and back on. Notes: (1) In voice modes (using the built-in DVR), only messages 1 and 2 are available, corresponding to BAND+ and BAND- in fast-play. (2) At present, message chaining (starting another message while one is already in progress) is only available in CW modes (with both normal and fast-play). 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Do we need 2 groups?
Between self-moderation and Eric's very reasonable tolerance of OT posts, I don't think further measures are necessary. Breaking it up into subgroups just means the experts we all rely on most will have less reason to hang around answering questions. That would be a very negative consequence. What would REALLY help is that more people use meaningful subject lines, particularly using Elecraft model numbers, and OT when that is the case. I filter out KX3 and K3 because I don't have those rigs. Lots of posts have to do with those two rigs, but don't note it in the subject line. Not a problem, though, because I have a functioning Delete key and I'm trained to use it. Ironically, this thread about OT complaints and splitting up the group is far less interesting than any of the OT threads that precipitated it.

[Elecraft] Playing with my KX3-2M
Finally hit a breather in my busy schedule* to spend a little time with the new 2M transverter module. *Just wound up running a week of W1AW/KL7 for 2m eme. My unit was one of the few that had to have the Rx fixed as result of field testing. Came back in great shape and verified the RF output to be 3w. I still don't have enough time to make the exhaustive frequency measurements that I want to evaluate for use with mw transverters that commonly use 144 as IF, but ...made some local 2m-FM contacts and noticed the receiver audio seemed scratchy, sort of like one would see with poor signals. That got me curious to make some tests with my other 2m-FM rig and that also seemed off. At the same time I decided to program the KX3 with the local NOAA Wx station (162.475) and it was terrible. I switched to my standard vertical dual-band base station whip and NOAA came at S6 loud and clear -wow! Quick check of the tower-mounted preamp shows its blown. It reverts to bypass by removing 12v power. BTW the preamp is connected to a yagi pointed toward Anchorage 70-mi north. The NOAA station is 20mi south. But the thing I wanted to say is KX3-2M Rx sensitivity at 162 MHz appears pretty good! Quick check of 2m Rx sensitivity was made using my XG3+30 dB step-attenuator and good it was hearing down to -137 dBm in SSB bandwidth. Now I am fixing a RFConcepts 2-23 30w linear amp to be driven by the KX3-2M. This amp is a very nice brick which is small enough to take on a plane in a briefcase when traveling. Being linear it can be used on 2m-SSB with the KX3-2M. Check out my new webpage for the 2M module: http://www.kl7uw.com/KX3-2M.htm 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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 Message delivered to arch...@mail-archive.com
[Elecraft] N1MM setup help
I am using my IBM Thinkpad with an older K1EL keyer. The keyer is plugged into the back of the K3 in the keyer socket. The USB connection from the K1EL keyer is hooked to the Thinkpad. The laptop is hooked directly to the K3 via its serial port; yes, a true serial port with a DB9 connector. Now comes the problem: Setting the com ports correctly. It has been years since I last hooked this together and I just today installed N1MM onto the recently installed OS. I know I need to set the com ports to get it running correctly. One for the serial connection and one for the USB connection. Reading the installation notes for N1MM just buries me in information when all I really need is a picture of which com ports to use. The last time I did this I just worked my way through all combinations until one magically worked. Currently I don't have that kind of patience :) Could anyone direct me to the short form of the instructions or give me a little hint as to which ports may work? By the way, the OS I am using on the Thinkpad is the last version of XP. 73, Kevin.

Re: [Elecraft] RF in the Trees
This guy comae up with a variation on the OCF Dipole that matches well on many bands and has been field tested in contests by a station in Germany. Lightweight, low profile, durable, especially good for QRP or field day operations. Maybe it will give you an idea or two...

[Elecraft] N1MM and K1EL Winkey

Re: [Elecraft] N1MM and K1EL Winkey
Kevin, If you have moved the USB connection from connector to connector, check your USB port assignment in Control Panel.

[Elecraft] Progress with N1MM
I can run the contest from the K1EL Winkeyer at this point and N1MM tracks the frequencies of the K3. But, N1MM keeps telling me I don't have a CW port selected even though I have set the COM1 port as such. The baud rates of the com ports on both the laptop and the K3 are the same which was causing one difficulty. However, this last problem seems to be very arcane. Luckily I can log on paper as I do for the few contests I enter. Any suggestions would be helpful. Kevin.

Re: [Elecraft] N1MM setup help
Hi Kevin, Setting up the K3 and the Winkeyer is actually pretty simple. Lets assume that you have connected your K3 to your laptop on your serial port. Let's also assume that you have connected your Winkeyer and that it has passed the communication test. Now your serial port is probably Com1. So open N1MM make sure you have the information and entry windows open. Now click on Config at the top of the entry window. Then select the very first line on the drop down menu called configure ports, mode control, ports, other. This will open the rather intimidating configurer window. Make sure the Hardware tab has been selected. Look at the first column, do you see Com1 on the left? Now click the little down arrow on that line and select the Elecraft K3 from the list that opens. Now push the set button on the right hand side. All the suggested Elecraft K3 settings have already been set for you. Just press OK down at the bottom. Now select the Winkey tab. Again, the settings have already been selected for you. Click OK at the bottom. When you do you will see the Winkey version appear on the Information window. Voila! You should be in business.

[Elecraft] N1MM lack of instructions
I finally guessed the correct setup. No searching of N1MM's documentation helped at all. It was simply guessing which made the setup work. Since COM1 is used by the Elecraft K3 and the Winkeyer uses COM4 I thought COM1 should be set as the CW port. No, this is incorrect. It is solely the control port and not the CW port. What is necessary is to go into setup from the Configure panel and check one box. That box says Winkey. I have yet to find this explained anywhere or by anyone. It was just random chance that lead me to the dialog box I needed. I picked COM4 and setup to get there. Once I checked the Winkey box I was able to use CW from the N1MM application. Now how many more hours will it take before I discover how to load a Field Day template? Does anyone use N1MM for a contest logger? Kevin.

[Elecraft] Finally got N1MM to work
It only took six hours this time to install and setup N1MM to run with my K3. Hopefully it will work tomorrow when I reboot that computer. I wish the documentation was not so confusing. Most application manuals I read are not so obfuscated. A few real world examples would have been nice. Simply guessing at the settings to make things work is a ludicrous method of obtaining the goal desired. If I had not found the Winkey check box by mere luck I would still be banging at the keyboard. A good index to the documentation would be nice since searching by suspected keywords did not work at all! Kevin.

Re: [Elecraft] KX3 self activites
I worked at KSBY-TV supporting myself in college. In the control room, large windows in the hall behind me, the transmitters were on the other side of the hall. Many meters, had to read and log them every half hour. Late at night, studying physics while on network with nothing local to do, I got this eerie feeling that all the meters were totally wrong and getting worse. I never could turn around quickly enough to catch them at it.

Re: [Elecraft] N1MM setup help
Yes, sometimes, trial and error works the best Kevin. Setting up for field day is also very simple. First open N1MM and make sure you are at the entry window. Now click File at the top. Click on new database on the menu that opens. For a file name I would suggest ARRL Field Day. Now click save. Go back to File and in the menu that opens select the first line new log in data base. In the window that opens, up at the top push down on the little down arrow and scroll through the alphabetical list until you see FD. Click on that entry. Now in the contest tab below look at all the pre-filled entries to see if they match your proposed operation. You can explore each by clicking on the little drop down arrow. My entries in the order listed are: Single-Op, All, Low, CW, (N/A overlay), Fixed, Assisted, One. You may wish to consult the rules to see what applies to you. Just press the button to the right labeled Show Rules. Now your sent exchange should be filled in according to the class of station that you have and your ARRL section. The example already filled in may already have your section but not your class. Now click on the tab called Associated Files. The first line refers to the Master.DTA Filename. It should be Master.DTA. Make sure you have the latest version installed on your computer. To check, close out the open window by clicking on OK at the bottom. Now to to the tab Tools on the entry window and select download latest check partial file. Follow the instructions on the website to download and install the latest file. While you're at it also _download_ and _import_ the latest Country File in the Tools menu. One last thing and we're done. Open the N1MM website and click on the Files Tab. On the menu that opens select sample function key files. Then click on the CW keys. On 6/27/2014 9:01 PM, Kevin wrote: Thank you.

Re: [Elecraft] KX3 self activites
Another Cal Poly grad? I was an EL major there from 1963 to 1965, US Navy from 1965-1969, and Math / Comp Sci from 1968-1971. It's a great place, isn't it? I remember a drive up Cuesta Grade and up the hill to KSBY once, we took a two meter radio and some sort of antenna up on that hill for some event. It was a long time ago, I can't remember why.

Re: [Elecraft] N1MM setup help
Sorry Kevin, I pressed send before I was quite done. In the CW keys right click on the one that reads FD-CW.mc. Download that file and save it to your N1MM directory. Now go back to the entry window, select file, open log in database, associated files, and in the CW function key filename line, click Change in the far right and find the sample function key file that you just downloaded. Click open when you find it. Then OK to close out the open window. Take a look at your entry window, see if the function keys are to your liking. If now they can be edited by going to Configure, change CW function key definitions. An editor will open and you can make the changes directly. Save the file and you are in business. I am sorry this took so long to explain, but it is much easier done than written about. With experience you will become a pro. If you have specific questions, do not hesitate to contact me. I am about done for the night but I'll be back early tomorrow. Hope to wrk you in FD. CUL. 73, Charles N2SO. On 6/27/2014 9:01 PM, Kevin wrote: Thank you.

Re: [Elecraft] N1MM lack of instructions
Kevin, Did you look at the Getting Started documentation at: http://n1mm.hamdocs.com/tiki-index.php?page=N1MM+Logger+Documentation It's pretty foolproof. For specific information on interfacing with a K3 see: http://n1mm.hamdocs.com/tiki-index.php?page=Supported+Radios#K3 http://n1mm.hamdocs.com/tiki-index.php?page=Supported+Radios#K3 On 6/27/2014 7:59 PM, Kevin wrote: I finally guessed the correct setup. No searching of N1MM's documentation helped at all. It was simply guessing which made the setup work. Since COM1 is used by the Elecraft K3 and the Winkeyer uses COM4 I thought COM1 should be set as the CW port. No, this is incorrect. It is solely the control port and not the CW port. What is necessary is to go into setup from the Configure panel and check one box. That box says Winkey. I have yet to find this explained anywhere or by anyone. It was just random chance that lead me to the dialog box I needed. I picked COM4 and setup to get there. Once I checked the Winkey box I was able to use CW from the N1MM application. Now how many more hours will it take before I discover how to load a Field Day template? Does anyone use N1MM for a contest logger? Kevin.

[Elecraft] Elecraft CW Net warning
Good Evening, Please don't wait for the net on Sunday. As usual on Field Day I will not be running either net. Why? As I learned from Tevye: the best thing to do is spread your arms wide and proudly state Tradition!. Don't worry, I'll be back next week checking in as many of you as I can hear. Good luck with Field Day and stay safe. Beware of the sparrow sized mosquitoes of the South, heat stoke of the Midwest, the sticky maple syrup of New England, dehydration in the Southwest, or hypothermia in the Pacific Northwest. Stay dry, let your generators cool before you refuel them, make sure they're grounded safely, watch out for falling antennas, don't eat too much :), and treat other operators with respect. Kevin.
