Meantime, I am running 100 Watts and am direct from antenna to the K3 - took the other stuff out of line. Lots of complaints about this, but has anyone tried reverting to an earlier firmware version? I've never had this problem, even once ... ever. Except for the tribander, my antennas are not really resonant and the tribander is getting so old I'm finding trap covers at the base of the tower. I don't remember my FW version off-hand, something like 1.3 or close, certainly not the latest. I guess I'm assuming that the older FW is either available on the E-site, or you saved it when you installed it. I would imagine it could help the E-engineers a lot to know that the problem you're experiencing is or isn't FW-related. "The Latest FW Isn't Always The Best For You." I update my firmware on all the E-things either when it fixes a problem or "undocumented feature" that I've actually experienced, or when it adds something I'll actually use. Other than that, if it works for me, I leave it alone. Sad part is that no one noticed the lack of power. Before springing for the KPA500, I ran my 1.2KW amp at 500W for a year. Neither I nor any of my regular contacts could tell the difference. Since we have a "smart meter," I can look up our demand on the power company's site, and looking at contest weekends where I really did put my butt in the chair, I think I might be able to see a small decrease. However, our biggest usage is pumping water to the 35+ valves that the irrigation system for the botanical garden I live in requires, so contest weakends may be in the noise. If anyone wants info on a 40 station irrigation controller, let me know, I built one. :-)) So far, the "smart meter" has not caused any problems around here, and last time I saw my VA doctor, he confirmed that I didn't need to put tin foil in my hat, all my problems are caused by accumulated birthdays and not taking real good care of my body in my 20's.

Re: [Elecraft] KX3 "Full" SDR
Let me say that I calculate path losses the same way I did as an engineer at the phone co when calculating the losses in fiber optic systems - the path loss includes all losses between the TX and RX. This is the path the signal takes, hence this is the path loss. We must deliver a certain amount of energy to the RX. If it is in the path and it has loss, it becomes part of the path loss. As best I can tell this is the same approach employed in VOACAP. There they call it system loss instead of path loss. But I believe it is the same quantity. If you chose to define it differently that is fine. And keep in mind that this does not include the gain of an amp or a beam. If you put those into the mix the RX noise level increases by several dB. You can call the level by whatever term you prefer. -27 dBm, 2 microwatts, S9+45. They are all the same. S9 is a reference point, so many dBm. TX/RX makes no difference. It is a signal level we are talking about. A level of S9 is something many hams are familiar with. They can relate to S9+45 better than they can relate to 2 uW. This is just like SWR = 2, return loss = 9.5 dB, voltage reflection coefficient = .33, power reflection coefficient = .11, they are all different ways of expressing the same thing. But far more hams know what SWR = 2 means than know what RL = 9.5 dB means. And, yes, the wideband noise emitted by any of the Flex TX is excessive. 73 de dave ab9ca/4 On 12/31/13 5:50 PM, Bruce Beford wrote: Dave, I agree with your math, except... Having a noise level of -27dBm delivered by the transmitter to the antenna system, does not mean the antenna has 100% radiation efficiency, yes? So -27dBm is 2 microwatts in transmitted noise to the antenna system, at this particular spacing, in a 500Hz bandwidth. You must make some allowances for not only path loss, but antenna efficiency on each end, yes? As I said, I am not trying to defend these performance (or lack thereof) claims. I just disagreed with the statement that the "Flex is transmitting wideband S9+45 noise" "S9+45dB" is a receive measurement, not a transmitter measurement. The Flex is sending 2 microwatts to the antenna at the frequency in question. Admittedly, that's too much, in many situations.

Re: [Elecraft] KX3 "Full" SDR
I am in general agreement with what Greg writes, below (but with some comments inserted); Date: Tue, 31 Dec 2013 12:38:28 -0500 From: Greg Troxel To: Don Wilhelm Cc: elecraft@mailman.qth.net, Craig Schroeder Subject: Re: [Elecraft] KX3 "Full" SDR There are several important questions that could be lurking behing "full SDR", especially since Craig talked about hobby aspects of SDR -- people often mistakenly equate SDR with "open-source SDR", blurring "functions are controlled by software" with "user can control functions by software". 1) Is the modulation/demodulation done in some sort of processor under software control, from a wide IF (perhaps at 0, perhaps higher)? This is the normal definition, and indeed the KX3 meets it. 2) Is the user of the radio able to change the firmwmare, in order to experiment or for other purposes? One might call this "user-changeable SDR". Here, the KX3 does not meet that definition -- while Elecraft has released updates and improvements and can be expected to keep doing so, users cannot improve or even read the software. x-x-x-x-x-x-x Here I must insert a comment that commercial SDR's do not generally offer "open source" sw to their customers, either. This is a special issue that fits one of ham radios treasured activities of being able to "roll your own" and redesign everything! I would maintain this is a small group in ham radio (even for a tech guy like me). x-x-x-x-x-x-x 2a) Can someone who changes the firmware share their improvements with the world? This is a further nuance, leading to "open-source SDR". Flex used to be like this, but I understand (from speaking to a Flex rep at Boxboro 2012) that the software used with their radios is now proprietary rather than open source. x-x-x-x-x-x-x Probably Flex has learned the hard way that opening up everything to general access has a huge customer service headache attached! Again you will not find this offered in commercial or military SDR's. x-x-x-x-x-x-x And, it is limited to Windows only, which leads to an unreliable system (as described by a Flex user who gave a talk at a local club). Note that there is hardly any discussion of KX3s locking up and being flaky and needing to be rebooted. Then there's a related question separate from SDR definitions, having to do with packaging and interconnects: 3) Does the radio function without having to carry along an external computer? There is great merit in a small low-power box being functional by itself. x-x-x-x-x-x-x I would venture to say you will not see the military running around with radios that require a computer to operate - they may use one as an accessory like a typewriter. x-x-x-x-x-x-x Craig: So it really depends why you think you want an SDR. If you want to understand the software and contribute towards a community of people improving it, the KX3 won't let you do that, and I would suggest that you look at GNU Radio and other open-source projects and their associated hardware (some of which has open designs). If you want a radio which has features typically achievable in SDR, and that you can expect to be improved by the manufacturer, and you don't mind not being able to change it (and that others can't either), then the KX3 fits the bill. If what you want is to experiment with code to demodulate, the KX3 is also a good choice because it provides I/Q output. But I know of no way to transmit custom signals (other than soundcard modes, which generally are viewed as below the SDR definition). x-x-x-x-x-x-x Yes, the soundcard interface is kind of limiting but still valid. I would see better interfaces coming in the future. x-x-x-x-x-x-x My advice is to think about what you really want in terms of an experimentation/learning platform vs. a really well designed useful radio. And if you are going to experiment with code, stay within the open-source world, so that you can share your changes with everyone. x-x-x-x-x-x-x My guess for 99% of hams the current SDR model is quite adequate as folks want to buy or download free sw as new stuff is developed by those technically able to produce it. In that sense the current crop of Flex and Elecraft SDR's are fine. SDR is a new acronym for folks to figure out and understand - this discussion is good for that!

Re: [Elecraft] KX3 digital modes problem
Jim, It is unfortunate that you do not have a microphone that works with the KX3. Right now, you do not know whether you have a KX3 problem or a problem with the interface output levels or with the cables. Do you have any other audio sources that you can drive into the KX3 microphone jack as a test? Yes, I understand that the interface(s) work with other rigs, but the question remains - is it providing the proper audio to the KX3? You should be able to drive the ALC indicator up to 4 bars with the audio from the interface. If that does not happen, then you will have to discover the cause - it could be improper cables, a fault in the cables, or it could be a KX3 problem. There are just too many variables at this point to say where the problem may be. 73, Don W3FPR On 12/31/2013 4:00 PM, Jim Fitzpatrick wrote: I recently purchased a KX3. I have made several hundred CW QSOs with it in the past several months. One of the main reasons for getting it is that I enjoy operating QRP while traveling and camping. I like to operate JT-65 HF with minimal power just to see what I can work. I have run into 2 problems with this radio. The first is I cannot get any power out when attempting to operate either JT-65 or RTTY (AFSK). The second is that I have been having problems with battery operation. The details on the first problem are as follows. When portable I operate using either a SignaLink USB sound card interface or a WestMountainRadio Nomic interface. I have been using these for several years with JT-65 and AFSK RTTY. I have used both of them with four different radios and have made thousands of QSOs without problems. The radios are a K-3, IC-7000, IC-706 and a Flex 1500. Attempting to operate digitally with the KX3 results in the PTT working with either interface, but no power output from the KX3. I am using commercial cables from the interfaces to the KX3. I have tried it with 2 different computers, both of which work fine with the other radios. I strongly doubt that the problem is with either the computers or either of the interfaces, they all work fine with my K3. I have read the manual 416 times to try to figure out what I may be doing wrong, but can find nothing in there that I am not doing correctly regarding menu settings, gain/compression controls, etc. I do not have a microphone that works with the KX3 so I cannot see if there is power out in SSB mode. I have tried it in both standard SSB mode and in Data mode (DataA). I have fiddled with the mic gain, the sound card output, and anything else I can think of. I am wondering if there is some secret menu setting I should be using or if there is actually a problem with the radio. I'm obviously hoping it is something simple and obvious that I am overlooking. The other problem has been operating with batteries. Using fully charged brand new NiMH batteries the radio simply turns itself off after I turn it on. I have the BAT MIN set at 8.4V. I measure the battery charge at about 11V. This should be enough to keep it running, but it doesn't even after I have enabled all the power saving measures suggested in the manual. Loading it up with 8 brand new Duracell AA batteries gives me 12.2V, and it seems to work fine just as it should.

Re: [Elecraft] KX3 "Full" SDR
The article itself is far less relevant to this discussion than the data included in it. There has been lots of complaining in various contest forums regarding the insidious wideband trash caused by rigs with bad phase noise, and if you think that 30 to 50 db difference is not noticeable at HF you either don't live in a very quite area (I do) or you don't do much contesting where several hundred other stations are operating at the same time on the same band. Besides, what do you think happens during events like Field Day, or when the ham three miles away is putting out that kind of trash??

His summation was that the Flex-1500 is marketed as being perfect for driving microwave transverters. His article outlines why this may not be true. The FLEX SDR radios are not as objectionable on the HF bands, where atmospheric and other noise dominates.

Re: [Elecraft] KX3 digital modes problem
Re: "Using fully charged brand new NiMH batteries the radio simply turns itself off after I turn it on." Several possibilities here. First be sure the battery connector is fully engaging the pins on the circuit board (reference Figure 8 of the KXBC3 Installation and Operation Instructions). Mine wasn't fully engaged and would occasionally become intermittent. Second, be sure the cells are good. Take them out and measure their individual voltages. They should be within about 0.1v of each other; also, any cells that are below 1.0v should be replaced. While a faulty cell may be flagged by the KXBC3 charger during charging, it is possible that one of them discharges very quickly after charging is complete. Are your cells relatively new and all of the same type? I was given an old set of 2500mah Ray-O-Vac NiMH cells, and they would discharge while sitting in the KX3 (or on the shelf for that matter) over a few days time causing the same symptoms you are seeing. Any of the modern "Low Self Discharge" NiMH cells should not exhibit this behavior, and will remain charged for a long period of time Mark KE6BB From: Jim Fitzpatrick Sent: Tue, Dec 31, 2013 at 1:01 PM To: Subject: [Elecraft] KX3 digital modes problem I recently purchased a KX3.

Re: [Elecraft] KX3 "Full" SDR
Dave, I agree with your math, except... Having a noise level of -27dBm delivered by the transmitter to the antenna system, does not mean the antenna has 100% radiation efficiency, yes? So -27dBm is 2 microwatts in transmitted noise to the antenna system, at this particular spacing, in a 500Hz bandwidth. You must make some allowances for not only path loss, but antenna efficiency on each end, yes? As I said, I am not trying to defend these performance (or lack thereof) claims. I just disagreed with the statement that the "Flex is transmitting wideband S9+45 noise" "S9+45dB" is a receive measurement, not a transmitter measurement. The Flex is sending 2 microwatts to the antenna at the frequency in question. Admittedly, that's too much, in many situations.

Re: [Elecraft] Shipping a K3
Bob, Many who ship USPS do not use Priority Mail Flat Rate because often it is more expensive than regular Priority Mail. If the item is heavy, or the distance is far, then flat rate will provide an advantage, but that is not universally true. I check the USPS shipping rates when packaging and give my customers the lowest price available, whether that be Flat Rate or regular Priority Mail. Most items I ship fit into a Large Flat Rate box, but for light weight items (K1s and KX1s) along with nearby shipping addresses, it is usually less expensive to use regular USPS Priority Mail. I am a small shipper, so I can afford the time and effort to compare prices. Elecraft OTOH ships enough in one day that it is not practical to compare prices for each USPS shipment, so they just choose regular Priority Mail. I would do the same if I had volume shipments. 73, Don W3FPR On 12/31/2013 6:25 PM, Bob wrote: I like and prefer Priority Mail for orders if that option is available.

Re: [Elecraft] KX3 "Full" SDR
Well, I don't understand your math . . . Yes, 100w is +50 dBm. The TX noise is 77 dB below the carrier (for a SSB bandwidth). We subtract 77 from 50 noise level = -27 dBm This is the level of the wideband TX noise as it leave the TX. S9 = ~ -72 dBm -27 dBm is 45 dB above -72 dBm Hence the TX noise level is S9+45 as it leaves the TX . . . Now . . . the RX noise level is whatever the TX noise level is minus the path losses. Assume skywave path losses of 100 dB. RX noise level is -100 - 27 = -127 dBm. This would be approx the MDS of most RX and would usually be buried in the band noise. Now assume ground wave path losses of 60 dB. RX noise level = -27 - 60 or -87 dBm. If S9 is -72 dBm this is only 15 dB below that or about an S6 noise level. The level of any RX signal is irrelevant (except for whatever AGC action it may induce). It is what it is. This is wideband noise which the RX will hear as wideband noise. The noise level will jump up each time the Flex is keyed. Note that no modulation need be sent. All that is necessary is to key the TX. And, no, the station listening to the Flex TX does not hear the noise. He hears the signal. The guy tuned to another signal, even one 300 kHz away, is the one that gets blasted by the wideband TX noise. And the paper linked-to was indeed about VHF/UHF contesting. But for those ops the path loss is mountain-top to mountain-top and is much less than skywave path losses. So any Flex model is really, really not welcome by the VHF contesting crowd. That was the point of the paper. And the same thing applies to most ground wave paths as well. 73 de dave ab9ca/4 On 12/31/13 3:38 PM, Bruce Beford wrote: For those, the noise from a Flex at 100w, at -77 dBc (which is -27 dBm), can be quite substantial.

I am not trying to defend the transmitted phase noise performance of the Flex products, but... Your math is flawed. Assume 100w transmitter is delivering +50 dBm to an antenna. (100W is 50 dB greater than 1 milliwatt) Also assume you are at a receiving station, and hearing this station at S9+30 dB, on a receiver calibrated to 6dB/S unit, S9=50uV at 50 Ohms, or -73dBm for S9. Your receiving the fundamental signal at -43dBm (S9+30dB). With the transmitted phase noise 77dBbelow the carrier, it would be received at -120dBm, or about S2. Granted, it would be 10 dB stronger (abt S3.5), if you were receiving the fundamental transmission at S9+40dB, etc. But... the Flex is not " transmitting wideband S9+45 noise."

Well my experience (hassle) with the UPS store is different. I had the local store owner state that their shipping charges are the same as UPS. That as as a franchisee that was all they were allowed to charge. He said this with a straight face too. It turns out he was truthful but deceitful. He did not disclose that "his" insurance rate was almost 3 times the UPS rate for the same coverage. So he lost it all. I had prior to this used his shredding service and bought some supplies through him. I opened an online account and just drop the packages off there now.

We had hoped to be able to operate on the same band on different modes.

Re: [Elecraft] Shipping a K3
Like just about any service, it's often the person you are interacting with who defines your experience of the whole organization. In our rural neighborhood my mailbox is several hundred yards from the house. Whenever I get a package too big for the mailbox, the mail carrier makes a side trip to my front door to deliver it in person. I don't know if that's according to the USPS rules, but what matters to me is that service is what our mail carrier, Karen, chooses to provide. 73, Ron AC7AC -Original Message- I've had a lot of trouble with the postal service. They now refuse to deliver packages to my house. They apparently found a rule that says if your house is more than 1/2 mile from the public roadway, they don't have to deliver parcels. So to save the driver 5 minutes delivering to my house I have to make a 1-1/2 hour round trip to the post office to pick up my package. FedEx, UPS, OnTrack and all other delivery companies do deliver to my house. But not the postal service. My experience is that USPS is a big, bureaucratic, semi-governmental organization that doesn't care about its customers.

My digital meter can not measure over 10 amps so the lower current measurements were made with it and the higher current measurements were read on the meter in my Alenco DM-330MV power supply.

This is what I have come up with using the formula in the handbook; Aqrm = NL + 10 x log (BW) Aqrm = interfering signal in db NL = noise level on the receive frequency in dBc BW = receiver IF band width in hZ (I am using a 500 hZ filter) Aqrm = -77 + 10 x Log (500) = -77 + 10 x 2.69897 = -77 + 26.9897 = -50.01 dB If the tx signal is S9 +20 dB then you add +20dB to the -50.01dB and you get -30.01dB which is a S4 signal. So a S4 signal is a lot of QRM. If the band width is 1000 hZ the signal would be S5 plus 3 dB. And all of this is at 350kHz away from the Tx signal. K3 Doing the same math but using the 120 dBc at 360kHz we get a interfering signal of -73 dB, which is 75 dB below an S1. Now no one has ever accused me of being the brightest bulb in the box, but this is what I have come up with. 73 and HNY looking forward to SKN in a few hours!

Same boat here. I gave up my PalStar tuner and a single 3-500 amp that worked flawlessly for the KAT500 and KPA500. Getting older, I wanted seamless operation from the PTT to the antenna. I still am wanting that - so we will see what the coming changes bring us. Meantime, I am running 100 Watts and am direct from antenna to the K3 - took the other stuff out of line.

Re: [Elecraft] KX3 / K3 Antenna Sharing
Some of the relay-based antenna switches actually have two sets of relay contacts between the antenna and the not-selected radio. This can improve the isolation. However the difference between "S9+" and "I can barely hear" is a whole lot of dB, and asking for complete silence is asking for a lot. http://www.qth.com/topten/abss.htm Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Bennett Sent: Tuesday, December 31, 2013 12:56 PM To: Elecraft Reflector Reflector Subject: Re: [Elecraft] KX3 / K3 Antenna Sharing Thanks for the info all - I looked at that Bird 6 position switch - about 1/2 the cost of my KX3 - yikes!

[Elecraft] KX3 digital modes problem
I recently purchased a KX3. I have made several hundred CW QSOs with it in the past several months. One of the main reasons for getting it is that I enjoy operating QRP while traveling and camping. I like to operate JT-65 HF with minimal power just to see what I can work. I have run into 2 problems with this radio. The first is I cannot get any power out when attempting to operate either JT-65 or RTTY (AFSK). The second is that I have been having problems with battery operation. The details on the first problem are as follows. When portable I operate using either a SignaLink USB sound card interface or a WestMountainRadio Nomic interface. I have been using these for several years with JT-65 and AFSK RTTY. I have used both of them with four different radios and have made thousands of QSOs without problems. The radios are a K-3, IC-7000, IC-706 and a Flex 1500. Attempting to operate digitally with the KX3 results in the PTT working with either interface, but no power output from the KX3. I am using commercial cables from the interfaces to the KX3. I have tried it with 2 different computers, both of which work fine with the other radios. I strongly doubt that the problem is with either the computers or either of the interfaces, they all work fine with my K3. I have read the manual 416 times to try to figure out what I may be doing wrong, but can find nothing in there that I am not doing correctly regarding menu settings, gain/compression controls, etc. I do not have a microphone that works with the KX3 so I cannot see if there is power out in SSB mode. I have tried it in both standard SSB mode and in Data mode (DataA). I have fiddled with the mic gain, the sound card output, and anything else I can think of. I am wondering if there is some secret menu setting I should be using or if there is actually a problem with the radio. I'm obviously hoping it is something simple and obvious that I am overlooking. The other problem has been operating with batteries. Using fully charged brand new NiMH batteries the radio simply turns itself off after I turn it on. I have the BAT MIN set at 8.4V. I measure the battery charge at about 11V. This should be enough to keep it running, but it doesn't even after I have enabled all the power saving measures suggested in the manual. Loading it up with 8 brand new Duracell AA batteries gives me 12.2V, and it seems to work fine just as it should. AUTO OFF is set to infinite. I'd appreciate any constructive ideas. Thanks.

Re: [Elecraft] KX3 "Full" SDR
While it is true that, for a station receiving via skywave on the HF bands, the path loss will usually drive the noise from a Flex TX below the distant stations noise floor, let us not forget those within range of the ground wave. For those, the noise from a Flex at 100w, at -77 dBc (which is -27 dBm), can be quite substantial. Recall that S9 is approx -72 dBm. A Flex is transmitting wideband S9+45 noise. I would think that a Flex would be absolutely intolerable for any event involving nearby stations, such as Field Day. And I would think anyone running a Flex who happens to have neighbors within a few miles would not be a popular fellow. 73 de dave ab9ca/4 On 12/31/13 12:57 PM, Bruce Beford wrote: Many people seem to be either forgetting, or missing the point of Leif's article (referenced below).

His summation was that the Flex-1500 is marketed as being perfect for driving microwave transverters. His article outlines why this may not be true. The FLEX SDR radios are not as objectionable on the HF bands, where atmospheric and other noise dominates.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
I reported this problem to support back in February, and though my question was responded to, it was never really answered -- I've been living with the problem since.., I'm sure support can look at the case, it was around February 7 of this year. Before I switched to KPA500/KAT500, I was running 12-1400 watts PEP from a SB-220 through a Drake MN-2700 tuner, with never an issue, so I don't think the problem is arcing connectors, balun, coax, antennas. Also the raw VSWR on my 75M antenna is about 2:1, maybe a bit better. (The K3 says 2:1, the LP-100A, 1.98:1), so I don't think the problem is brought on by excessive SWR...

The K3 and P3 work quite well with Rumlog. Connect things normally: K3 <--> P3, P3 <—> USB Interface, USB Interface <—> Macintosh. Then look at how the serial interface is configured for Rumlog. It most likely needs to be set to 38400bps to properly communicate with the P3/K3.

Re: [Elecraft] Shipping a K3
Alan, Don't spread that news to my post office! My carrier has to travel 3/4 mile on a private road to get to the mailbox, and then if parcels will not fit in my large mailbox, he comes up my 1/4 mile driveway to deliver them to the front door. I have always had great service from the postal carriers. At least my local postal carrier does seem to care! Of course, UPS and FedEx also deliver to the door too - we have a sufficiently large area for them to turn even a large truck around with ease. 73, Don W3FPR On 12/31/2013 2:55 PM, Alan Bloom wrote: I've had a lot of trouble with the postal service.

[Elecraft] Progress on K3/KPA500/KAT500 SWR/band change (+ improved K3/KAT500 integration)
Hi all, Yesterday we analyzing the reports of unexpected SWR faults and band changes. They fall into a few categories, and we have a good handle on how to deal with all of them in firmware. (Faults caused by antenna/feedline/connector problems are the only exception. These can cause SWR to change asynchronously, and there's no way to fix this in firmware. The amp and tuner are correctly going into bypass mode, retuning, or inserting attenuation in such cases.) Unfortunately the KAT500 changes cannot be completed immediately because the responsible engineer is leaving for a week's vacation starting tomorrow. But the changes are fairly simple, so shortly after he returns we'll be sending out new firmware to a group of customers who have reported problems. Sorry for the delay. In addition to firmware changes needed to handle SWR and band-change issues, we'll be improving integration between the KAT500 and the K3. For example, you'll be able to use the K3's ANT switch to select antennas at the KAT500. We're also working on a K-Line Installation guide, intended to be a more convenient resource for all of the information needed to interconnect and setup the K3, P3, KPA500 and KAT500. We hope to have this out a month or so after all of the pending firmware changes have been completed. 73 (& Happy New Year) Wayne N6KR __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX3 "Full" SDR
Many people seem to be either forgetting, or missing the point of Leif's article (referenced below). The entire thrust was in the context of using an HF transceiver as an IF rig with VHF/UHF/SHF transverters. Band noise on those higher freqs is low enough that transmitted phase noise can be an issue. This is especially true when running high power. His summation was that the Flex-1500 is marketed as being perfect for driving microwave transverters. His article outlines why this may not be true. The FLEX SDR radios are not as objectionable on the HF bands, where atmospheric and other noise dominates.

Yes. You were transmitting on 50.376 MHz. The forward power was measured at 1411, which is a bit north of 300 watts. It appears that the amplifier key line is not being interrupted by the KAT500.

Re: [Elecraft] KX3 "Full" SDR
An equally important consideration for any rig, SDR or not, is what kind of signal you are transmitting. All of the FLEX rigs have a very bad reputation for transmitting lots of wideband phase noise, while the KX3 is near the top of the heap for cleanliness of signal. The difference between the two is not slight ... it is spectacular. Coincidentally enough, there was a very recent thread here discussing this very topic. Based upon the published test results I've seen, if everyone used FLEX SDR rigs nobody would enjoy SDR rigs ... or any other rigs for that matter.

There are several important questions that could be lurking behing "full SDR", especially since Craig talked about hobby aspects of SDR -- people often mistakenly equate SDR with "open-source SDR", blurring "functions are controlled by software" with "user can control functions by software". 1) Is the modulation/demodulation done in some sort of processor under software control, from a wide IF (perhaps at 0, perhaps higher)? This is the normal definition, and indeed the KX3 meets it. 2) Is the user of the radio able to change the firmwmare, in order to experiment or for other purposes? One might call this "user-changeable SDR". Here, the KX3 does not meet that definition -- while Elecraft has released updates and improvements and can be expected to keep doing so, users cannot improve or even read the software. 2a) Can someone who changes the firmware share their improvements with the world? This is a further nuance, leading to "open-source SDR". Flex used to be like this, but I understand (from speaking to a Flex rep at Boxboro 2012) that the software used with their radios is now proprietary rather than open source. And, it is limited to Windows only, which leads to an unreliable system (as described by a Flex user who gave a talk at a local club). Note that there is hardly any discussion of KX3s locking up and being flaky and needing to be rebooted. Then there's a related question separate from SDR definitions, having to do with packaging and interconnects: 3) Does the radio function without having to carry along an external computer? There is great merit in a small low-power box being functional by itself. Craig: So it really depends why you think you want an SDR. If you want to understand the software and contribute towards a community of people improving it, the KX3 won't let you do that, and I would suggest that you look at GNU Radio and other open-source projects and their associated hardware (some of which has open designs). If you want a radio which has features typically achievable in SDR, and that you can expect to be improved by the manufacturer, and you don't mind not being able to change it (and that others can't either), then the KX3 fits the bill. If what you want is to experiment with code to demodulate, the KX3 is also a good choice because it provides I/Q output. But I know of no way to transmit custom signals (other than soundcard modes, which generally are viewed as below the SDR definition). My advice is to think about what you really want in terms of an experimentation/learning platform vs. a really well designed useful radio. And if you are going to experiment with code, stay within the open-source world, so that you can share your changes with everyone. 73 de n1dam __ 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] Shipping a K3
Since the question was asked, I thought I would share my experience in shipping my K3 from Ohio to Elecraft in California last August. I thought I would be smart and ship my K3 via air to speed its delivery and avoid excessive handling. This turned out not to be the case and it cost almost twice the price of ground shipping. Because of a holiday and weekend, the K3 took only one less day than if I had shipped it by ground. I tracked it every day and it was scanned and transferred multiple times before it arrived in Watsonville, CA. I double-boxed the radio with plenty of packing. When I got to the UPS station, I purchased $4,000 worth of insurance. When I told the clerk the description of the radio and the insurance amount, he wanted me to undo all of the packing and show him the radio! It took me quite a bit of describing exactly how I packed it, and the clerk had to get a supervisor's approval to avoid doing so. Apparently some UPS offices have a policy that requires opening the package if the declared value is over $1,000. I recommend that you check in advance and take pictures of your packing method to avoid opening the box. On the way from the factory, I choose UPS ground at half the cost of sending it there. It arrived in fine shape, SINGLE boxed, and was held in place with special foam. The radio traveled back to Ohio mostly by rail car and was handled and scanned far fewer times than going it. It took seven days to get home. Incidentally, the factory repair service was superb, several updates were done free, and the radio performs better now that when I bought it in 2009. 73, Dennis W0JX Milan, OH __ 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] Serial Cable routing

The ACTIVE use of the serial connection is between P3 and K3 so that the P3 knows frequency, and between the K3 and the computer for logging and control. That's the only connection that most of us leave in place. The only need for serial to the KAT500 and KPA500 are for occasional firmware updates, which, as has been noted, don't come very often. So every 6-9 months I fire up the K3, P3, KPA, and KAT utilities, check for firmware, load them into K3 and P3 with the routine serial connection, and then use another serial cable to to update KAT and/or KPA when needed. 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

Craig, Most of the filtering is done in DSP.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
Hi, Are you in AUTO mode when this is happening? I found it wise to switch to manual mode when finishing the quick tune after a QSY. Before I got into that habit this was happening a number of times. I am running barefoot with no internal tuner in the K3 so those are not a factor. The MFJ tuner I was using before I got the KAT500 also had this problem so it's not unique to the KAT500. For the MFJ I ran a wire out to the remotely located tuner connected to the TUNE button so I could run it in manual (really semiautomatic) mode.

Re: [Elecraft] KX3 "Full" SDR
Craig, The KX3 is a "full SDR" radio (the K3 is as well). By virtue of the modulation and demodulation all being done the firmware rather than in hardware. Yes, the KX3 does have knobs which are used to pass parameters to the firmware - the "computer" is inside the KX3 and no external computer is required. There are some (maybe many) who believe an external computer is required for the radio to be a "full SDR" but I am not in that group. There are others who believe that one must have a panadapter display to be a "full SDR", and again, I am not a member of that 'camp'. The KX3 with an external computer can have a panadapter display.

Re: [Elecraft] Shipping a K3
Hi Gary, Shipping anything large has gotten to be expensive. Since you used the term "first class mail" I can tell you haven't shipped a large package for quite a few decades. Simply put, if you have the dimensions of your box, the weight, and the insured value the easiest way to determine shipping cost is to go to the UPS and USPS web sites and enter the data. You'll want to choose "Ground" for UPS and "Priority Mail" for USPS. The Post Office will pick it up at your house for no extra charge. UPS will charge for pickup but you can drop it at any of the many UPS shipping stores for free. Or you can hand it to a UPS driver when he is making a delivery also free. You can do the package labeling yourself directly off of your printer. You just have to register a few details and use your credit card. Or you can take the package to the Post Office or UPS store. The price is a little higher if you take it to the Post Office but it is the same if you take it to the UPS store. If you live in my town it will take 45 minutes at the Post Office or 1 minute at the UPS store. 73, Mike K2MK Gary Smith-2 wrote > I'm going to be shipping my K3.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
Thanks, Ray. We think there are several issues. At least some of these reported problems have been resolved by changes to the antenna system (connectors, baluns, and the antenna itself). If there is flashover or heat-related impedance change, the KAT500 measures a changed SWR and reacts by interrupting the key line and retuning (in mode Auto) . Some cases are related to antennas whose unmatched SWR is outside the KAT500's spec of 10:1 at 600 watts, 3:1 SWR at 1000 watts. If the antenna system (before matching) exceeds these limits, often a match can be found, but this match shouldn't be used at power above our specified threshold. More heat is dissipated by the tuner's components. If this gets way out of hand the antenna tuner does fault, which bypasses the ATU, the amplifier key line is interrupted, and the ATU red FAULT LED is illuminated. We log these faults and you can see them in your KAT500 Utility fault log display. The fault description is along the lines of "power too high for unmatched SWR'. And I believe in some cases the frequency counter is counting a signal other than the primary transmitter RF signal. I don't have much control where the pulses we count come from, but I might be able to better qualify the use of that count. If the frequency count is seen as a band change, the ATU can change antennas. We're digging into all these, and there will be firmware change to address those we can fix in firmware. I am not asserting that every one of these observations comes from antenna system problems. But some do. If your specific problem is due to a coax connector, balun, or antenna that changes impedance at high power, the changes I make in firmware aren't going to fix that problem. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ray Coles Sent: Tuesday, December 31, 2013 5:29 AM To: Elecraft@mailman.qth.net Subject: [Elecraft] K3/KPA500/KAT500 SWR problem As the original poster of this problem topic I have been transfixed by the subsequent correspondence on the matter.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
Was on 75 this morning and carefully monitoring what is going on with the tuner. I am running 100 Watts through the KAT500 - the amp is on standby until this gets fixed. No smoke wanted here hihihi. Results: Several times during QSO the tuner would click and make noises - this while on MANUAL. No changes noted on any meters - and I monitor output from the K3 and before the antenna. No unusual deflections noted. Then comes the real sadness: No one noticed that I wasn't running the amp! Not a single comment - negative about my signal. Makes me stop and think about making some near future changes in the equipment lineup. I think this "problem" may have been a good wake up call on what I really need. Odd the lessons we take away from conversations on the reflector.

Re: [Elecraft] Shipping a K3
Dear OM Poul Erik, This would increase costs for Elecraft in dealing with Europe and therefore need to result in higher sales price. Elecraft prices are not exorbitant. They do not use a dealer network. If you purchase from a dealer in the UK the rule of thumb is your price in Pounds will be about the same as that in Dollars or about 65% higher and often the UK warranty is not as good as that in the USA. I personally hope Elecraft never locks us into dealerships. You can still purchase directly with a savings in cost or you can purchase from a dealer and take advantage of their warranty. Mind you the savings are not 65% as you must pay for shipping and taxes. We pay for living in Europe but there are also some things we prefer here. Elecraft support is good and so if you can localize the fault to a module then the module could be returned rather than the whole radio.The Elecraft products are reasonably reliable and not prone to failure. I do not believe we are going to do better. I would not find radios from other manufacturers to be better supported. You are right to explore the topic. Please forgive my counter view.

I did run into situations where such signals induced up to 5 volts into low band antenna. Then KAT500 counts that signal as reflected and thinks that SWR is very high. One may try to connect broadband spectrum analyzer to the antenna and see what is going on. If it is broadcasting signal well below ham bands then high pass filter between the tuner and antenna can help.73, Igor UA9CDC” __ 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
[Elecraft] KX3 / K3 Antenna Sharing
I've got a KX3 and a K3 - I want to share an antenna between the two radios. I do this now by manually detaching the coax from one and connecting it to the other. Are there any quality coax switches on the market that have adequate isolation between ports that I could use for this purpose?

Re: [Elecraft] KX3 Headphone Clicks
I am using a Heil headset and a set of Bose head sets and I have no key clicks at all.

Re: [Elecraft] Shipping a K3
Please be aware, if you are from outside the US, when sending Elecraft equipment for repair *including warranty repair* you will have to pay for the return shipping. For European hams, Elecraft is offering the option to have faulty equipment repaired by a partner in Italy. However, unlike your American ham friends, for warranty repair you will be requested also to pay for the return shipping - also if you choose to have the faulty Elecraft gear repaired "locally" in Europe. It may be that the same applies to other ham-radio manufacturers. But we got used to get a better service from Elecraft than from the others. Concerning shipping that's however not the case. In my job I have over the years sent professional equipment for warranty repair both in the US and in Canada, and I believe those companies did pay for the return shipping without asking. I earlier - in this forum - have asked for a comment from Elecraft to this service related issue, but Elecraft decided not to comment (hopefully they will do now). 73 and best wishes for everybody in 2014 OZ4UN Poul-Erik K2/100, K3/100, KPA500 (for warranty repair!), KAT500 -Oprindelig meddelelse- Fra: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] På vegne af Rick Dettinger Sendt: 31. december 2013 09:27 Til: g...@ka1j.com Cc: elecraft@mailman.qth.net Emne: Re: [Elecraft] Shipping a K3 If you pack it, the USPS will advise when you go to the Post Office.

What I'm hearing is probably the same thing, except I dont have NR switched on... I'll read through the list of things to do to reduce the effect and see if any work out.
