Re: [Elecraft] K3/100 or KX3 with all the options?
Well my answer is get them both! I have the K3/10 and ordered the KX3 with KXFL3, KXAT3, and MH3. I left off the CW paddle and NiMH charger as I will use an external key and battery for portable use. I will order the KX3-2M and KXMM3 when available. I might have been tempted to get the KX3 instead of K3/10 if it had been available in 2010 when I bought the K3. It will be less expensive and provides almost all that I desire. But having dual-Rx and transverter I/F is essential for my activities ...so I'm keeping the K3! The K3 really is a keeper! 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] KX3 and Data modes
OK, I guess I need to repeat what I said. The 25H is SPECIAL order from Radiodan W7RF mailto:rfpo...@radiodan.comrfpo...@radiodan.com, who has the ability to run NBS traceable calibration on these elements. Any Bird element can be modified to a different power range (if you do a search you should find some sites that talk to this). But most of us do not want to dig into one that far. I think the wrong impression has been taken of Bird's statement of accuracy. I doubt the inaccuracy is a fixed amount that is the same at any reading. More likely Bird does its calibrations at full scale and this is the accuracy that they will warrantee. Seem more reasonable that the error is relative to the level of the reading. The actual adjustment is a variable cap inside the element. That and a resistor determine the level the element functions at. But that being said, I have no proof the element in question is any better than reading 25w +/- 1.25w. Ideally, I would have sent the meter to Radiodan to be calibrated with the element. Then he could have specified what the accuracy was for the calibration. But this is a brand-new element, freshly calibrated. Should I doubt it in favor of my 35 year old 100H element? Especially since resolution of reading 12w is much worse on the 100 scale than on the 25 scale. There is only one way for me to determine what the accuracy is. That is by observing the waveform across the dummy load with my scope, calculating Vrms from the peak-peak voltage and using that to determine power using V^2/R, assuming the load is not reactive. Well I might do that out of curiosity. That is probably the most accurate way for most hams to measure power (unless you are very rich and own a calorimeter). I did power measurement at 500-KHz by using my scope since I have no elements that work below 2-MHz. My 100w 500-KHz transmitter is equipped with an RF ammeter for measuring/monitoring power. For normal daily ham measurements I am willing to assume that the new element is my most accurate. Will it matter much if I am off 1.25w? BTW it could be better than that.

Re: [Elecraft] K3/100 or KX3 with all the options
Dave, I have a KX3 for field test. There is something eerie, shocking, about how something so tiny performs the way it does. Great fun! But I guess one will eventually get used to it. Some aspects that will stay with you: The KX3 is designed to sit on a table top, Supported by its rear feet. The display is, at least for now, optimized for viewing from below the perpendicular direction rather than straight on. Great for something you move to different locations (hiding it from the view of the xyl?) but, with wires hanging from the sides, it doesn't create the look of a permanent installation. If you want to hook up a lot of things to it at a given time, you are going to find unavoidable limitations that the K3 doesn't have in terms of size and number of connectors etc. The lack of a second independent receiver is a significant difference, but the KX3 does have dual watch that covers a limited range, and there is no extra charge for it. While you can get a built-in ATU with great range, you only get one antenna connector for HF/6m. There again, if you build a complex station you will have a lot of external things that make the KX3's size advantage less important, and the xyl might find the collection of equipment more unsightly than a single K3 box. Firmware-wise the KX3 is where the K3 was years ago. CW and SSB work great, but if you want FM or AM you will need to wait a little bit. Bottom line: You really want both. The K3 is more expensive, but you could perhaps offset the difference by picking up a used one, or a 10W model, and enjoy it while KX3 production and refinement ramps up. BTW with the conditions we now have on the higher HF bands, it is really easy to work DX with 5 or 10W, even with a poor antenna, as the KX3 has shown me. Years ago someone gave me a little 3 ft baseloaded whip made by Maldol. I hid the shameful thing away in a drawer, knowing that it will radiate only a very tiny fraction of the applied power. Now I tried it for the first time (on the KX3, outdoors) and worked Japan on CW on the first call. Like I said, there is something unreal about it... It definitely gives you more opportunities for hamming. 73, Erik K7TV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of David Stratton Sent: Tuesday, March 13, 2012 3:45 PM To: Elecraft Reflector Subject: [Elecraft] K3/100 or KX3 with all the options My radio needs are very modest for I am not a contester, or DXer, or even one who makes a lot of contacts but I do listen quite a bit.

The actual adjustment is a variable cap inside the element. That and a resistor determine the level the element functions at. The manufacturer's accuracy specification is what it is...not what you might think is reasonable. Most analog meters are calibrated in % full scale due to the inherent error in visually interpreting a needle on an analog scale. This visual error is constant at all readings, hence the specification is a percentage of full scale. This is exactly why DMMs replaced analog meters (e.g. Simpson, Triplett, etc) decades ago. But that being said, I have no proof the element in question is any better than reading 25w +/- 1.25w. Ideally, I would have sent the meter to Radiodan to be calibrated with the element. Then he could have specified what the accuracy was for the calibration. The LP-100A is factory calibrated (NIST traceable in 11 frequency bands) to 5% of reading (3% typical). As stated before, the key difference with the analog Bird is that accuracy is specified in % of reading...not % of full scale. There is only one way for me to determine what the accuracy is. That is by observing the waveform across the dummy load with my scope, calculating Vrms from the peak-peak voltage and using that to determine power using V^2/R, assuming the load is not reactive.

This is essentially what the LP-100A does using an A/D converter and microprocessor. Besides being much more accurate, it provides many other useful features such as Z, R, X, SWR, SWR and phase versus frequency, Smith Chart output, translates coupler load Z to antenna load Z (for remote measurements), peak-to-average (useful for measuring SSB compression), etc. Measurement range is 1-3000 Watts over 1.8-54 MHz with the standard coupler (higher power available as options) at full rated accuracy. For normal daily ham measurements I am willing to assume that the new element is my most accurate. Will it matter much if I am off 1.25w? BTW it could be better than that. That is the worse-case specification. I can understand being locked in to Bird because of your significant investment in 16 slugs (typically $60-80 each on eBay not counting the Bird 43 itself). However, for anyone considering a truly state-of-the art Wattmeter, it's hard to beat N8LP's LP-100A because it does so much more than simply measuring power. If you add up the total cost of a Bird plus multiple slugs to cover the same power ranges, the LP-100A is a steal. Like all of Larry's products (LP-PAN, LP-Bridge, etc) the engineering and support for the LP-100A is first rate (e.g. providing a customer upgrade path from the original LP-100 to the LP-100A). http://www.telepostinc.com/ I have no connection with Larry other than being a very satisfied customer with several of his products. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-and-Data-modes-tp7368721p7371630.html Sent from the Elecraft mailing list archive at Nabble.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
Re: [Elecraft] KX3 and Data modes
Ed, Yes, the most accurate is to use the 'scope with a 10X probe to measure the RF voltage across the dummy load. No need to convert to RMS and all that - use this formula - Power = the square of the peak to peak RF voltage divided by 400 if the load is 50 ohms (8R if other than 50 ohms). You can substantiate that by formula manipulation - the sqrt of 2 terms fall out. 73, Don W3FPR On 3/14/2012 3:56 AM, Edward R.

Re: [Elecraft] KPA has FAILED...high SWR reported by K3 when amp in Operate
Hi, The amp has worked well with 500 watts out, and in standby works fine with 100 watts and the power shown on the led meter is correct. When in operate, it shows high swr with only 1 or 2 watts of drive. So something in the t/r switch has failed. I guess. Thanks for the reply.

I have used it for a couple of months on my remote station that is controlled by a prototype K3/0 terminal. It consists of a K3 macro and an additional wire in the AUX cable between the K3 and the KPA500. This simple control is all that is really necessary for remotely operating the amp, as it works along with the AuxBus communications to both enable/disable the amp and also report what the amp is doing.

The main difference is that instead of being powered ON in standby mode, the amp turns off. Since the MOSFETs have no filaments to wear during power cycling, this does not present a problem. If the amp faults, a message appears on the controlling K3's VFO B display. Press the macro key once to turn OFF the amp, then again to turn it back on.

Since this is the first K3 macro I have written, and since it worked the first time, I did not bother to optimize it to use the minimum reliable wait times.

Re: [Elecraft] KPA500 RemoteRig
No. The K3 cannot control the KPA, so this is not feasible. If you want to use the KPA with remoterig, you will need to set up a separate serial communications channel between the remote computer and the KPA. Note that while the KPA sends the K3 information, the K3 does not talk back to the KPA. The KPA does listen to the K3's band pins, but this does not provide reliable information to allow communications. Jack B, W6FB On Mar 14, 2012, at 10:04 AM, David F.

Re: [Elecraft] KPA500 RemoteRig
Jack is not quite correct here, as we are currently able to set the KPA500 into operate and standby via a K3 macro that togges a pin on the K3 aux connector. The K3 then displays the Operate / standby status on the VFO B when this changes. Bob, K6XX, our KPA500 program manager, figured out how to do this.

Re: [Elecraft] Make the Feet Stickier

[Elecraft] newbie setup questions on memory editor repeater setup
Hi from KT4JR, wife of K4MWE, and new co-owner of a K3 with 144mHz transverter built in. I have not been able to understand how repeaters are supposed to be set up and I am hoping some kind spirit out there can clarify for me. I have entered the repeater frequency in the VFO A cell of the memory editor on the computer. I have selected FM so that offset and PL tone choices appear next to the VFO B cell. I can put in the offset and PL tone, but do I enter a frequency in the VFO B cell? I can't tell whether the program would apply the offset to the VFO A frequency or to the VFO B frequency, so I don't know whether to put the same entry in A and in B, put the actual transmit frequency in B, leave B blank, or what. Say we have a repeater with VFO A frequency at 145.20 mHz and a negative offset of 0.6 mHz. So my transmit frequency needs to be 144.60 What should my table row look like? What goes in the VFO B cell? Name VFO AVFO BoffsetPL tone ABC club 145.20 _-0.6 82.5 A related question (why I can't figure out the above) is where on the K3 I could actually see the result. Is there some way I can display the frequency I am transmitting on using the display screen of the K3? Do I need to set the K3 to split before using a repeater, in addition to setting the above? If there is a pre-fab dummy guide for repeater set-up, please point me toward it! Finally, I have not figured out the squelch yet either. is there a set-up guide for squelch? Clearly this radio is amazingly flexible, and I need to keep on studying! THANKS for your help!

[Elecraft] Antenna switch question
Currently I physically change coax lines when switching the antenna from one HF rig (K3) to the other HF rig (TS480). Of course it is fool proof when it comes to making a transmit error. That said, I'd like to use a coax switch for this purpose. Years ago I did this often, however, rigs were less complex and sensitive back then - so I trusted simple coax switches. I do not run rigs simultaneously on different antennas and bands the operation is very simple. Question is: What coax switches are recommended for this job and what db isolation should I be looking for? I do recall that in the USAF - all antenna switching at listening posts was done with patch cords and panels. No switches. That was in the days of the R390.

Re: [Elecraft] KPA500 RemoteRig
Hello, The RRMTCBL set comes with a DE-15 to RJ45 cable. The DE-15 side is not molded, it snaps together. If you are going to purchase the RemoteRig set, its required to have the RRMTCBL set also (unless your making your own).

Re: [Elecraft] P3SVGA
Hi Mike, The 12 DC input to the P3 is connected internally to two DC/DC converters. These both have over current protection and limit at less than 1/2 amp each. Probably worst case is 1 amp. Of course if the cable itself shorts out or the regulators somehow short at their inputs we would exceed that. Certainly putting an external fuse inline with the P3 power supply wouldn't hurt. 73, Paul Mike K2MK wrote Hi Paul, I'm curious about circuit protection. If I connect this cable directly to my 35 amp 12V power supply is there any over current protection within the P3? I understand that the cable itself might go up in smoke but at the present time I'm only really worried about the P3. 73, Mike K2MK Paul Saffren N6HZ wrote Hi Bill, We're going to start shipping a 6' 2.1MM power cable with every P3SVGA board ordered. The other end of the cable is bare and can be used to connect the P3 directly to your 12V mains. This should start by tomorrow or the next day. If your SVGA hasn't shipped yet, there'll be one in the box. Anyone who has already received their SVGA board can simply contact the factory and we'll send one out. 73, Paul (n6hz) -- View this message in context: http://elecraft.365791.n2.nabble.com/P3SVGA-tp7366923p7373655.html Sent from the Elecraft mailing list archive at Nabble.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
Re: [Elecraft] K3/100 or KX3 with all the options
Erik K7TV states: Firmware-wise the KX3 is where the K3 was years ago. CW and SSB work great, but if you want FM or AM you will need to wait a little bit. What? Here is what I read at the top of the KX3 listing: 160-6 meters, SSB/CW/DATA/AM/FM modes I will be sorely disappointed if it is not capable of FM use with my 144-28 transverter. I can wait for the KX3-2M module but not for having FM. If this is so then I hope this will be added, soon. This is hard to believe, really? I can use the K3, of course, but then it is not available for other use.

Re: [Elecraft] KX3 and Data modes
Well we have taken this off topic a bit. Bill W4ZV writes of the advantages of the LP-100A over analog meters. Definitely a nice piece of equipment that can do much more than a simple power meter. However, it only reads to 54 MHz. I also occupy 144/222/432/927/1296/2400/3400/10,368 MHz bands so I need to read power to 10-GHz. With the Bird43 I can get up to 2.4 GHz with expensive elements (I have a 10K for 1100-1800 MHz). Then I switch to my HP432A mw power meter which is limited to +10mw, but can read to 18 GHz. I have 900w directional couplers and coaxial attenuators for measuring higher power with the HP meter. Also, I would not feel comfortable using the LP-100A at 50-foot in a light rain on my tower checking cable loss or power levels. The Bird is the industry standard instrument for field use (inaccurate as it is). So this is NOT and argument of what is better. If some day I can afford it, the LP-100 would be real nice in my shack. For 99% of the readers on this reflector the LP-100A will suit them perfectly. The other 1% of us have different/additional needs. I suppose we have beat the Bird to death?

Hi all, The KX3's LCD is identical to the K3's, except that it its polarizer optimized for 6 o'clock viewing, similar to that of LCDs in digital multimeters and other instruments with a top-facing display. Since the LCD has a low muliplex rate, it has very high contrast, and as Erik observed, works with a wide range of viewing angles -- but not from above the display. The contrast is not presently adjustable, but we can add this if warranted. This may extend the range a bit further.

For mobile operation I would think the mobile mount that sits on a gooseneck would allow you to adjust the radio orientation for perfect contrast. 73, Erik K7TV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Andrew Moore Sent: Wednesday, March 14, 2012 4:43 PM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3/100 or KX3 with all the options Is the viewing angle adjustable? Is so, by how much? Is contrast adjustable? (or is that accomplished by changing the viewing angle?) While a below the perpendicular optimization works well for tabletop use, I am concerned about mobile use - something I intend to do with the KX3. The rig would likely be mounted with the display perpendicular to line of sight (i.e., flat on view) -- or even such that viewing is above the perpendicular (like when the rig is sitting on the floor/console area). --Andrew, NV1B ..

By above I mean an angle higher than perpendicular to its face (also known as normal to the display in engineering terms). Displays that require such viewing angles use 12 o'clock displays. The K3 falls into this category, since most operators either look directly on the LCD (normal to it) or from above.

[Elecraft] Alternative Amplifiers for HF
I will not advertise very often on this list, but I do want to remind folks that I am developing a couple HF amplifiers that will work with either the K3/10 or KX3. One takes 5w drive to provide 140w output (12vdc), and the other takes 12w drive to provide 275w (28vdc). Both are assembled versions of the kits offered by CCI with addition of chassis, connectors, LP filters, TR relays in a complete package vs the plain pcb amp parts kit that CCI offers. Essentially, I am offering a kit building service + packaging. Its taking me a bit longer to work out some details like the custom pcb for the six-band LP filter and some delays in suppliers for my 300w prototype (I am building for myself). On air reports have been good, so far, but full testing remains after the LP filter installation. This should not be confused as a KPA250 (smile): A more basic amplifier for a little less money (take the link at the bottom line in my signature). Hoping to have start date in mid-April. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] Antenna switch question
recently ther was a similar question in QST's QA and they showed what they had at W1AW. rather than an antenna switch the have an antenna patch bay. so I created a similar setup. your needs are simpler than mine but the basic Idea would work for you. I have some vintage rigs in addition to the main station so I use a panel that has several SO239 connectors, each SO239 has a line that goes to the antenna connection of each rig, two SO239s in the case of rigs with two antenna connectors like the K3. Each SO239 is labeled for its corresponding rig.Then since I have 3 antennas I have 3 short coax leads with PL259s each lead goes to and labeled for each antenna. so when I change antennas or rigs all I do is connect the lead from the antenna I want to use the SO239 corresponding to the rig I want to connect it to. there is no way to connect a rig to a rig in error this way or more than one rig to one antenna. It essentially brings all the antenna connectors from the radios to one panel and the same for the antenna leads.the last thing is I have three dummy SO239 connectors that are grounded one for each antenna. when an antenna is not in use or when I am not operating the station I connect the antennas to the ground connectors for protection from static. in your case all you need is one lead from your antenna and an SO239 for each antenna connector on your rigs. This is easily expandable and has excellent isolation that is probably better than any antenna switch.Just remember to use a metal box and to be sure its connected to the station ground.if you scrounge a bit you probably will find that you can make this type of system for far less than buying an antenna switch.

Of course it is fool proof when it comes to making a transmit error. That said, I'd like to use a coax switch for this purpose. Years ago I did this often, however, rigs were less complex and sensitive back then - so I trusted simple coax switches. I do not run rigs simultaneously on different antennas and bands the operation is very simple. Question is: What coax switches are recommended for this job and what db isolation should I be looking for? I do recall that in the USAF - all antenna switching at listening posts was done with patch cords and panels. No switches. That was in the days of the R390.

[Elecraft] P3 SVGA Frequency Display
Having a large screen is pretty nice. However, the frequency display at the top is pretty small. It would be nice if the size of the numerals used could be enlarged (and/or set by the user). It would also be nice if we could change the colors on the SVGA display. 73, Ed - K6CTA __ 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] P3 SVGA Frequency Display
You can set the font size for the P3 screen in the menu. Not on the external monitor? Maybe it doesn't change the end-point and center frequency display, I'll have to check. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org On 3/14/2012 8:43 PM, Ed Schuller wrote: Having a large screen is pretty nice.

[Elecraft] Elecraft KX3 Programing Cables
All 2 questions? 1 Is the KXSER the same as the programing cables furnished with the W2 and XG3 ? I've got three of these cable and don't need more. 2 Does the KXUSB cable need specific drivers for the OS? I'm running XPE. What chip is used for the USB to RS232 ? Thanks for any info.
