Re: [Elecraft] P3 or Sub Rx?
I might have to re-evaluate. For casual split chasing the P3 can still be awesome. And the P3 is just so cool for general use. If I were funds limited I would definitely buy a P3 and save up for the sub RX. Having both is the greatest thing since sliced bread. 73, Mike K2MK ae4pb wrote I like the way you split it up.

Re: [Elecraft] P3 or Sub Rx?
I think some folks may have forgotten that a subreceiver is not required to locate a DX station's listening frequency in a split pileup. Before second receivers were available we all did what we had to do . we quickly switched between VFOs and tuned the listening range . and it worked . not all the time . but most of the time..and it still works .. And guys who are good at it can do as well as others with two receivers. The second receiver, of course, makes it easier.. And a panadapter makes it even better. I had my second receiver long before I bought a P3 and thought I was in great shape . but when I started using the panadapter it opened up an entire new world and I would no longer want to be without it. I still believe however that the P3 is much more valuable when it's used along with a second receiver, so I would still buy my second receiver first. It is really the huge pileups where the real value of the combination of subreceiver and panadapter will be revealed. To illustrate, I made several videos while tuning through the huge pileups generated during the recent K1N dxpedition. Here's one that will speak for itself.

Re: [Elecraft] K3/K3S DB9 Conn - If it plugs in, then it should work
Standard use of connectors is a good thing. It saves the various number of different connectors that we must retain for various uses. However, there is no standards in the ham radio community regarding the use and types of connectors. In the military, they use a different connector for every different application and a different connector for each series of equipment. The result is that no two connectors are really alike. However, the advantage is the fact if one didn't have the proper connector and cable for the specific application, then the user could not connect anything. Both methods are correct just as both methods are incorrect, depending on the users point of view. 73 Bob, K4TAX K3S s/n 10,163 On 8/23/2015 10:25 AM, Jerry Moore wrote: I respectfully offer that it's a very good thing Elecraft used a commonly found connector in their radio designs. One bane of technology is when manufacturers use a myriad of proprietary connections. The huge advantage that we have in using common connections is the availability of plugs, sockets, and cables.

In the case of Elecraft radios with a DB9 connection we CAN use an RS-232 spec cable from the rig to our computer with the requirement that certain pins or wires be removed/cut/disconnected due to the nature of the connection. The Beauty of RS-232 is that it's a 3 wire system. The other connections are typically used for HARDWARE support (DTS/RTS) and aren't required for RS-232. So out of a DB9 connection we are left with 6 usable lines. What's a better design, combining purposes into a common connection where the consumers are technically skilled and educated, or having 10 extra connections on the back? If you were homebrewing the radio how would you build it? I'm betting that most of us would use single connectors and bundle the functions/features there. It just makes more sense. One thing that may help would be to label a warning on the connector if you may tend to forget that it's not a modem connection, rather, it's a multi-function DB9 connection. Just my opinion.

Re: [Elecraft] P3 or Sub Rx?
Regrettably, the JAs are catching up to the EUs, but generally true. As to the original question, I use neither, but do have the near equivalent of the P3. an SDR-IQ used as a panadapter. Although this could be used as a second RX, I have enough difficulty listening to one RX, I don't need to be further confused with a second. A couple of more QSLs for 30-meter QSOs and I will have 8-band DXCC.

Re: [Elecraft] [K3] what audio passband should I expect in TX DATA/DATA A mode?
Hi Pf, Most tone modes operate at an offset from carrier frequency, so that the audio frequencies of interest are more or less cenetered in the filter passband. I believe the JTx modes are already in the 1200 to 1500 Hz range so no offset is required. The crystal filter being used only restricts the bandwidth of the RX chain (1st IF). The DSP imposes its own audio filtering on the baseband, and that's what you're seeing as rolloff below ~300 and above ~3500 Hz. 73, matt W6NIA On Sun, 23 Aug 2015 19:03:21 +0200, you wrote: Hello, I'm dabbling with wsjtx, and I see that my rx audio has some definite roll off at 300 Hz and 3500 Hz.

Also are you ready to spend 25$ per connector because your application differs in some way and everyone has to invent a new connector for a new use which can never benefit from economy of scale. Or perhaps we should just quit inventing anything new. Aircraft safety is a completely different animal, where the money *WILL* be spent for safety issues bearing on loss of life, even if an item now costs $1000 instead of $10 because it is now a very specific quality-warrantied small-volume item that can never be mass-manufactured in 100,000 or 500,000 count runs.

Don't EVER put any male DB9 or DB15 or DB25 in any female DB9 or DB15 or DB25 without knowing what is on all the pins. And then what is DB25, serial or parallel port, or something weird? You always have to look at a DB25 which could be anything. Look at the back of a MicroHam box sometime, which has dozens of specialty connections to DB25's. Separate one of a kind jack for each cable connection? We really do hate to RTFM, don't we... I heard one XYL remark at a wives-invited ham function that her husband wouldn't RTFM any more than he would ask for directions, or even look at the all-language comic book assembly guide for that Christmas present, some assembly required. A friend of mine blew up a beautiful Alpha 99 he'd gotten off eBay for a really good price because he didn't read the manual for setup and fed 240V to a transformer that was strapped by the previous owner to 120. That was really expensive. I remember him saying that if I mentioned RTFM even once he'd come after me with a club. His eBay savings was wiped out and quite a bit more by the repair cost. But it was just one more of a bazillion examples of the trouble we cause ourselves in every aspect of life by our seeming intransigent unwillingness to RTFM before making assumptions and sticking things in things.

[Elecraft] If it plugs in, then it should work
I would agree with Ted in many instances (especially where safety is paramount), standardization is a necessity (excellent examples are given by Ted). That said, I would have to disagree with him if we try and apply that rational across the board. For instance, I do think applying the if it fits, it should work is practical for ALL electronic devices. Using a fully loaded K3S as an example, there are (not counting the ground lug) twenty four jacks on the back, and 2 on the front; requiring 13 different types of connectors (SO-239, BNC, Anderson Power Pole, RCA/Phone, 1/4 mono jack, 1/4 stereo jack , SMA connector, 1/8 mono jack, 1/8 stereo jack, USB, RJ45, DB15, and last but not least, an eight pin mic connector). If you were to apply the if it fits, it should work rule to the K3S, it would now require twenty six different types of connectors (double what we now have). O yes, even the ANT 1 and ANT 2 need to be different (maybe ANT 2 should be a N connector). WIth Radio Shack going tits up, it is hard enough finding the 13 types of connectors we need today; can you imagine trying to find twenty six different types just for the K3? And if you happen to have a VHF/UHF radio, it should have different connectors than any on the K3 or (for that matter) power amp; God forbid you inadvertently connect the output of your 1.5 KW amp to the ANT jack on your VHF radio!! Anybody who plugs a cable into a socket just because it happens to fit is a fool; especially amatuer radio operators, we all passed tests on radio theory and should know what all the inputs and outputs on our radios are for and how they are used. As for the DB15, it is marked ACC, it is not labeled VGA; why anyone would think it should be connected to a VGA monitor is beyond me?? Do you assume all radio manufactures use the same pinouts for their RJ45 or 8 pin mic connectors, and connect any mic to any radio? And yes, Bob (K4TAX) said it all; it is very important to read and understand the manual before plugging or inserting any connector into any hole on any radio today.

Line boys, as they¹re called, are no more or less cautious than the rest of us, but the theme is that people make mistakes so the systems in which they work should be engineered to prevent those mistakes or to prevent them from doing any harm. Ditto in medicine. Patient safety was significantly advanced when the oxygen and the anesthetic gas fittings were made different enough that oxygen couldn¹t come from anything but the oxygen supply (e.g. noninterchangeable screw threads). Patient safety gurus have also insisted that wrist bands used in every hospital everywhere not only have standard language, but also standard colors so that, in a rush, a band announcing an allergy (red) couldn¹t be confused for a DNR (purple) even though the words on each are clear. And crash carts should be in exactly the same place in every hospital ward. Until very recently some surgeons marked an X on a limb to mean cut this side, while others marked it to mean don¹t cut this side.

Re: [Elecraft] If it plugs in, then it should work
I agree with both Richard (K8ZTT) and with Guy (K2AV), in that all safety and error prevention strategies have to be subject to a practical cost-benefit analysis. That’s true even in healthcare — when you receive a transfusion, the transfused blood type is checked five or six times, not ten or fifteen, even though that might add a sigma or two to the mismatch incidence rate. Everything has declining marginal returns and some things have returns that start out less than their costs. No argument there. That said - and again confessing that I am not an electrical engineer - there may be some things that could be addressed cost effectively. For example, the reverse polarity problem that Alan (G4GNX) mentioned. Would it be cost effective to have reverse polarity supply and use connectors made green rather than black, or something like that? That shouldn’t cost too much. I don’t mean to be passionate about this. But as a lawyer (and a pilot) and a professor of healthcare policy, I have spent a fair part of my careers helping clients overcome inertia in advancing safety in the fields where I’ve worked. Reading that RTFM may be enough just struck me as out of phase with all of the QA literature of the last 15 years. It is essential that operators study the manual, of course; but it is not sufficient. Systems should assume that human error will happen anyway, and be robust enough to block the errors that inevitably happen. Again, I agree that when the cost of more attention to prevention exceeds its value in the practical world, that should be the end of it. And so I’ll go QRT with my part in this thread . . . Thanks for the comments and replies. As always, I gain a lot from this reflector. The benefits are worth far more than the cost. Ted, KN1CBR On 8/23/15, 10:39 AM, Guy Olinger K2AV k2av@gmail.com wrote: Good luck retrofitting that on 15 year old electronics. Also are you ready to spend 25$ per connector because your application differs in some way and everyone has to invent a new connector for a new use which can never benefit from economy of scale. Or perhaps we should just quit inventing anything new. Aircraft safety is a completely different animal, where the money *WILL* be spent for safety issues bearing on loss of life, even if an item now costs $1000 instead of $10 because it is now a very specific quality-warrantied small-volume item that can never be mass-manufactured in 100,000 or 500,000 count runs. I'll pay my portion of the cost of all of that, to be safe on my airplane trips. But my K2 ain't an airplane, and I don't sit in it at 35,000 feet doing 500 knots. On reason K2's are affordable is because they do NOT use a lot of specialty one-of-a-kind items. And how many would be complaining if it needed a hard to find specialty plug on the back. We can't afford stuff made idiot-proof to the extent that RTFM is never needed for success DB9 and DB15 are used for all kinds of non-standard stuff, all over the place (not just Elecraft)... Don't EVER put any male DB9 or DB15 or DB25 in any female DB9 or DB15 or DB25 without knowing what is on all the pins. And then what is DB25, serial or parallel port, or something weird? You always have to look at a DB25 which could be anything. Look at the back of a MicroHam box sometime, which has dozens of specialty connections to DB25's. Separate one of a kind jack for each cable connection? We really do hate to RTFM, don't we... I heard one XYL remark at a wives-invited ham function that her husband wouldn't RTFM any more than he would ask for directions, or even look at the all-language comic book assembly guide for that Christmas present, some assembly required. A friend of mine blew up a beautiful Alpha 99 he'd gotten off eBay for a really good price because he didn't read the manual for setup and fed 240V to a transformer that was strapped by the previous owner to 120. That was really expensive. I remember him saying that if I mentioned RTFM even once he'd come after me with a club. His eBay savings was wiped out and quite a bit more by the repair cost. But it was just one more of a bazillion examples of the trouble we cause ourselves in every aspect of life by our seeming intransigent unwillingness to RTFM before making assumptions and sticking things in things. We shouldn't be asking others to make it safe for our failure to RTFM. YOU blow it up, YOU suck it up.

Re: [Elecraft] K3/K3S DB9 Conn - If it plugs in, then it should work
I respectfully offer that it's a very good thing Elecraft used a commonly found connector in their radio designs. One bane of technology is when manufacturers use a myriad of proprietary connections. The huge advantage that we have in using common connections is the availability of plugs, sockets, and cables. The responsibility we have is to always ensure the connections are as intended. In the case of Elecraft radios with a DB9 connection we CAN use an RS-232 spec cable from the rig to our computer with the requirement that certain pins or wires be removed/cut/disconnected due to the nature of the connection. The Beauty of RS-232 is that it's a 3 wire system. The other connections are typically used for HARDWARE support (DTS/RTS) and aren't required for RS-232. So out of a DB9 connection we are left with 6 usable lines. What's a better design, combining purposes into a common connection where the consumers are technically skilled and educated, or having 10 extra connections on the back? If you were homebrewing the radio how would you build it? I'm betting that most of us would use single connectors and bundle the functions/features there. It just makes more sense. One thing that may help would be to label a warning on the connector if you may tend to forget that it's not a modem connection, rather, it's a multi-function DB9 connection. Just my opinion.

Re: [Elecraft] K2 calibration questions
John, Certainly, this is a valid reflector for any Elecraft product. Don't worry about exactly 4.000 MHz on that reference oscillator. It is only important that it be right on just before running CAL PLL followed by CAL FIL - and the frequency may not be exactly 4.000 MHz when set properly anyway. That check in the manual was intended not as a calibration point, but only as a check to see if the oscillator was actually in close range of where it needs to be. When not running CAL PLL and CAL FIL, the K2 does not depend on that oscillator at all, it uses the data stored in memory during those routines to know what frequency to display. If you really want to fine tune the K2 dial calibration, go to the article on my website www.w3fpr.com and follow the procedure there. You will need to use Spectrogram or other audio spectrum analyzer to correctly tune in WWV and also to judge the width and placement of your IF filters. If you need spectrogram, look for the links near the bottom of my Home webpage. Those are links local to my website and those copies have been virus scanned many times and are known to be 'clean'. Be aware that due to limitations in the BFO DAC, you may find up to a 20Hz error in the final dial calibration results. That was quite tolerable until recently when new data modes (such as JT65) were developed requiring greater frequency accuracy. The K2 may not be suitable for those modes for that reason. 73, Don W3FPR On 8/23/2015 2:02 PM, John Wiener wrote: Hi Do people still ask about the venerable K2 on this group? hi my K2 serial # 5312 : I built it 9 yrs ago now.

Re: [Elecraft] If it plugs in, then it should work
You will never win! Many years ago we designed a military unit that had many I/O ports, so we chose a selection of MIL STD connectors with different shell sizes, numbers of pins, plugs/ sockets, orientations etc. to make it soldier proof. What we didn't realise until later was that if you used enough force you could get a 14 pin plug to mate with a 19 pin plug with the same shell size!

That said, I would have to disagree with him if we try and apply that rational across the board. For instance, I do think applying the if it fits, it should work is practical for ALL electronic devices. Using a fully loaded K3S as an example, there are (not counting the ground lug) twenty four jacks on the back, and 2 on the front; requiring 13 different types of connectors (SO-239, BNC, Anderson Power Pole, RCA/Phone, 1/4 mono jack, 1/4 stereo jack , SMA connector, 1/8 mono jack, 1/8 stereo jack, USB, RJ45, DB15, and last but not least, an eight pin mic connector). If you were to apply the if it fits, it should work rule to the K3S, it would now require twenty six different types of connectors (double what we now have). O yes, even the ANT 1 and ANT 2 need to be different (maybe ANT 2 should be a N connector). WIth Radio Shack going tits up, it is hard enough finding the 13 types of connectors we need today; can you imagine trying to find twenty six different types just for the K3? And if you happen to have a VHF/UHF radio, it should have different connectors than any on the K3 or (for that matter) power amp; God forbid you inadvertently connect the output of your 1.5 KW amp to the ANT jack on your VHF radio!! Anybody who plugs a cable into a socket just because it happens to fit is a fool; especially amatuer radio operators, we all passed tests on radio theory and should know what all the inputs and outputs on our radios are for and how they are used. As for the DB15, it is marked ACC, it is not labeled VGA; why anyone would think it should be connected to a VGA monitor is beyond me?? Do you assume all radio manufactures use the same pinouts for their RJ45 or 8 pin mic connectors, and connect any mic to any radio? And yes, Bob (K4TAX) said it all; it is very important to read and understand the manual before plugging or inserting any connector into any hole on any radio today.

I believe the JTx modes are already in the 1200 to Matt 1500 Hz range so no offset is required. Hi Matt, actually, I'm seeing JT9 stations transmitting at 3400 Hz, and who knows if there are some even above that. JT65+JT9 uses quite a wide receive window.

Re: [Elecraft] P3TXMON question?
This seems to have things really screwed up. Yes, the Bird 43 is a 5% of F.S. accuracy instrument. The Bird 43P is somewhat less accurate, although 5% F S with carrier, and more like 8% F S or so in peak mode. In measuring a 100 watt radio with a 100 watt F S slug would seem to be most accurate.Total accuracy decreases as the indicated value approaches the left side of the scale. Now using a 250 watt slug to measure a 100 watt radio, the earlier states that most accuracy is to the left of center, which by the way, is the compressed side of the scale. This makes no sense as the scale markings are much more difficult to approximate.In fact the most accurate area is to the right of center toward full scale is the expanded scale which is where the highest accuracy actually occurs. With a 100 watt radio and a 100 watt F S slug the error is +/- 5 watts at 100 watts. Using a 250 watt element and measuring 100 watts near center scale the error is more like +/- 12.5 watts or 5% of the F S value. If one measures the same power source with identical elements and gets different results, they should refrain from buying ham fest elements for indeed the elements are not identical. To wit, I purchased 3 new 100 watt elements and 3 new 2500 watt elements. They all give identical results +/- the width of the pointer. I don't buy ham fest Bird elements as I find they are junk and not worth the brass they contain. And remember, Bird 43 instruments are calibrated for only a 50 resistive load. Any other load being used leaves one with a best guess situation as to actual power. 73 Bob, K4TAX K3S s/n 10,163 On 8/21/2015 11:48 PM, Wes (N7WS) wrote: So by your logic it would be best to measure one Watt using a 100W element.

Re: [Elecraft] If it plugs in, then it should work
Whilst much of this may be true, it certainly isn't the case in the electronics industries (including Ham Radio) no matter how much we would wish it. A classic case is the 2.3mm power input plug (which is really a line socket) which is used on radios, power tool chargers, cell phones, laptop PCs and just about every wall wart in existence! When we pull the new appliance out of its box along with its charger, it's a fair assumption that the charger will be the correct voltage and it will work and cause no damage. If the charger dies and we have to source a new one, we expect the manufacturer to provide the correct device, PROVIDED that we quote the correct model number. If we go to an alternative supplier, WE are expected to check the voltage and current requirement and order accordingly. If we don't do that we are inherently STUPID! Remember in all this, the plug on the end of the wire is the SAME, it's use is not. We may also find that the polarity has been reversed on one particular model and what we thought was positive center, is no longer the case. This IS the case for some commercially built Ham Radio rigs and for some musical keyboards, to name but two. It is up to US the USER to check before plugging it in and if we don't we are again STUPID! All this for one style of connector with only two connections - wow!!! I've seen 5 pin DIN plugs used on Ham Radio rigs, I also use EXACTLY the same plug for MIDI on musical instruments. They are wired differently, the voltages, currents and signals are different and if I presumed that I could simply interchange the plugs, I would consider myself very STUPID! I would prefer Elecraft to have NOT used the same connector for RS232 and for AUX, for one reason only. In a moment of stupidity (yes I have them) I could absent-mindedly plug the wrong connector into one or more orifice. However, Elecraft obviously did not know that I have these moments of silliness, so have chosen to not attempt to save me from myself. This leaves me with three choices: 1) Don't buy the radio. 2) Buy the radio and modify it to a non-(Elecraft)-standard connector. 3) Buy the radio and RTFM - thoroughly! C'mon guys, if you've bought a kit (even a solderless kit) and you consider yourself capable of successfully assembling it, doesn't it tend to prove that you are two things at least - 1) You can read and follow instructions. 2) You are not the average appliance operator. As Radio Hams who have been to Radio Ham School, I really hope that the above two qualities truly apply. 73, Alan.

Re: [Elecraft] K3/K3S DB9 Conn - If it plugs in, then it should work
I respectfully offer that it's a very good thing Elecraft used a commonly found connector in their radio designs. One bane of technology is when manufacturers use a myriad of proprietary connections. The huge advantage that we have in using common connections is the availability of plugs, sockets, and cables. The responsibility we have is to always ensure the connections are as intended. In the case of Elecraft radios with a DB9 connection we CAN use an RS-232 spec cable from the rig to our computer with the requirement that certain pins or wires be removed/cut/disconnected due to the nature of the connection. The Beauty of RS-232 is that it's a 3 wire system. The other connections are typically used for HARDWARE support (DTS/RTS) and aren't required for RS-232. So out of a DB9 connection we are left with 6 usable lines. What's a better design, combining purposes into a common connection where the consumers are technically skilled and educated, or having 10 extra connections on the back? If you were homebrewing the radio how would you build it? I'm betting that most of us would use single connectors and bundle the functions/features there. It just makes more sense. One thing that may help would be to label a warning on the connector if you may tend to forget that it's not a modem connection, rather, it's a multi-function DB9 connection. Just my opinion.

Re: [Elecraft] K2 - KPA100 RS232 interface repair
Some of the pins on the AUX I/O connector meet parts of the RS232 spec, but other of the pins are used for an elecraft proprietary expansion interface. So, from an electrical perspective you can say it is actually a mix of both RS232 (partial) and AUX I/O. From a physical connector perspective, it is definitely not RS232, which is why you need to make an isolation/breakout cable. This is explained in the KIO2 manual. The main K2 manual doesn’t really seem to emphasize the point that severe damage can result if you connect this port directly to the serial port on a PC without making up an appropriate isolation/breakout cable. Due to the potentially serious consequences, I would have thought a warning in the main manual would be appropriate. -- 73 de Matt VK2RQ Le 23 août 2015 à 3:22:23 PM, Richard W.

Historically, RS232 was used in electromagnetic applications where there was a need to drive a relay with line levels. Since modern equipment doesn't need this - since TTL became commonplace in the 1970's - and since many lower power devices no longer have 12V power supplies, it has been practice to observe a ONE state at a voltage of 3V+.

A classic case is the 2.3mm power input plug (which is really a line socket) which is used on radios, power tool chargers, cell phones, laptop PCs and just about every wall wart in existence! When we pull the new appliance out of its box along with its charger, it's a fair assumption that the charger will be the correct voltage and it will work and cause no damage. If the charger dies and we have to source a new one, we expect the manufacturer to provide the correct device, PROVIDED that we quote the correct model number. If we go to an alternative supplier, WE are expected to check the voltage and current requirement and order accordingly. If we don't do that we are inherently STUPID! Remember in all this, the plug on the end of the wire is the SAME, it's use is not. We may also find that the polarity has been reversed on one particular model and what we thought was positive center, is no longer the case. This IS the case for some commercially built Ham Radio rigs and for some musical keyboards, to name but two. It is up to US the USER to check before plugging it in and if we don't we are again STUPID! All this for one style of connector with only two connections - wow!!! I've seen 5 pin DIN plugs used on Ham Radio rigs, I also use EXACTLY the same plug for MIDI on musical instruments. They are wired differently, the voltages, currents and signals are different and if I presumed that I could simply interchange the plugs, I would consider myself very STUPID! I would prefer Elecraft to have NOT used the same connector for RS232 and for AUX, for one reason only. In a moment of stupidity (yes I have them) I could absent-mindedly plug the wrong connector into one or more orifice. However, Elecraft obviously did not know that I have these moments of silliness, so have chosen to not attempt to save me from myself. This leaves me with three choices: 1) Don't buy the radio. 2) Buy the radio and modify it to a non-(Elecraft)-standard connector. 3) Buy the radio and RTFM - thoroughly! C'mon guys, if you've bought a kit (even a solderless kit) and you consider yourself capable of successfully assembling it, doesn't it tend to prove that you are two things at least - 1) You can read and follow instructions. 2) You are not the average appliance operator.

Re: [Elecraft] K3S or K3
What is leading you towards considering a K2? What do you plan to use it for? I really enjoyed building and using my K2. The QSK on it is smooth and silent, whether QRP or with the KXPA100, and I love being able to switch seamlessly between paddle and straight key without having to change anything on the radio. I miss the PX3 panadapter when using the K2 -- maybe at some point I'll tap the IF and use a softrock SDR + laptop to get a panadapter display. I haven't used the K2 for any digital modes so far -- I think there are some mods recommended first. Frequency stability could possibly be a concern with some of the more fussy digi modes -- although I have to say the K2 I bought/built last year came with all the latest improvements and the stability is really very good, certainly more than enough for CW and SSB. Maybe some other K2 owners can comment on their digimode experiences.

Re: [Elecraft] [K3] what audio passband should I expect in TX DATA/DATA A mode?
Hi Guys, As an active WSJT-mode user, I'll attempt to clarify this set of issues. For a more complete answer, download the WSJT 10 and WSJT-X pdf documents. WSJT 10 and WSJT-X are designed for the rig to be set for the full USB bandwidth of an average radio. Each mode has an agreed upon slice of each of the HF and VHF bands. For JT65, WSJT-X includes as defaults the dial frequencies for those agreed upon slices, which are from about 400 Hz to about 3 kHz above the dial frequency. The 400 Hz and 3 kHz points are the result of the IF filters, and can be varied a bit from one radio to another. On 20M, for example, a dial frequency of 14,076 kHz puts JT65 between 14,076.4 and 14,079. The slice for JT9 is 2 kHz higher, with a dial frequency 2 kHz higher. This puts their operating slice between 14,078.4 and about 14,081 kHz. Note the overlap, which is intentional. WSJT-X can be set to decode BOTH JT65 and JT9. If, for example, you call CQ with a dial frequency of 14,076 and 2.2 kHz audio, it will be within the passband of other radios tuned to 14076, and they can decode you. Go higher than 3 kHz audio and you're taking your chances. :) This one for Matt: Joe Taylor, K1JT, the inventor of the WSJT modes, strongly recommends that the rig be set for full USB bandwidth, and that we allow his software to do the filtering to separate signals from each other. We talked about this at Pacificon several years ago. The reason is simple -- filters creates phase shift, and phase shift is the enemy of good decoding. Another thing -- WSJT-X is undergoing extensive development, and will eventually include most WSJT modes, not just JT65 and JT9. The latest versions of WSJT-X have added a feature that, if the rig supports it, will set the rig for split mode with different audio tones on the TX than the RX but setting the split so that they come out on the right frequency! Again, RTFM -- this time the WSJT-X manual. 73, Jim K9YC On Sun,8/23/2015 12:51 PM, Pierfrancesco Caci wrote: Matt == Matt Zilmer mzil...@roadrunner.com writes: Matt Hi Pf, Matt Most tone modes operate at an offset from carrier frequency, so that Matt the audio frequencies of interest are more or less cenetered in the Matt filter passband.

Hi Matt, actually, I'm seeing JT9 stations transmitting at 3400 Hz, and who knows if there are some even above that. JT65+JT9 uses quite a wide receive window. Matt The crystal filter being used only restricts the bandwidth of the RX Matt chain (1st IF). The DSP imposes its own audio filtering on the Matt baseband, and that's what you're seeing as rolloff below ~300 and Matt above ~3500 Hz. Yes, and that was what I wanted to know. I've read in this mailing list that the DSP limits the audio at 4 kHz. I'm seeing it roll off at little above 3400. The low end rolls off at around 300, so I'm getting an audio passband of ~3100 Hz.

Re: [Elecraft] [K3] what audio passband should I expect in TX DATA/DATA A mode?
Yes, and that was what I wanted to know. I've read in this mailing list that the DSP limits the audio at 4 kHz. I'm seeing it roll off at little above 3400. The low end rolls off at around 300, so I'm getting an audio passband of ~3100 Hz. I wonder if this is normal, or if there's something else I can tweak in the settings. It depends on your roofing filter ... If you have an AM (6 KHz) or FM (13 KHz) filter, you will see 300 Hz to 4200 Hz with FC=2.20 and BW=4.00 (at -3dB). If you only have a 2.8 KHz filter, bandwidth will be around 2800 Hz (900 - 3700 with FC=2.20 and BW=4.00 or 400 - 3200 with FC=1.60 and BW=4.00).

Re: [Elecraft] If it plugs in it should work
There is no doubt there are many fields where being able to plug something wrongly is life threatening or way too expensive an outcome. But, there are many more electrical/electronic systems than different plugs and sockets. It is simply not realistic to achieve although a connector with several key-way options can give 2^n different fits. Edge fit PCB connectors used that method.Witness the number of different mike plug options even for mating plugs. The two pole version used by Kenwood and Yaesu some 20 years ago were different polarity. Realistically we are forced back to colour if possible (PS2 mouse keyboard) and good labels. As soon as third party kit is introduced then all bets are off.73 Alan G0HIQ __ 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

Tuning it is so very easy now---all I have to do is watch the advancing wave of noise and signals rise until the crest of the wave is centered on my P3 screen! Voila! I set the span to 200kHz and the delay to about 6ms and the results on the P3 remind me of my old body surfing days in KH6 as I would often watch the waves off to the side (like seeing a cross-section) until I saw one I wanted to try. Worth every penny to me now that I found a slightly different than intended use for it with my magnetic loop antenna. Other Elecrafters with sharp-tuning high Q loops like mine should take note as the P3 becomes an essential operating aid when tuning them for resonance at the desired operating frequency. Thank you, Elecraft for making my radio life a little bit easier! 73, Jeff, NH7RO __ 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] P3TXMON
That's just the problem. The K3 is so clean that it's almost boring to watch the display. Although, I can see the RFI that occurs with my fan dipole connected to the outboard tuner with using the amplifier on 160m (it clears when I disconnect it). I am getting more value from the Wattmeter and SWR displays, but watching the waveform while I talk is neat. I have yet to transmit PSK or another digi mode with the P3TXMON in line. Maybe this evening! 73, Nate -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

Re: [Elecraft] P3 Button settings
I put the Peak Toggle and the Fixed Tune Toggle on buttons. To capture the measurements that I want to save to a USB drive, I have the commands to Freeze the display and to save the screen assigned to buttons on one of my P3s. The other P3 has more span settings. 73, Jim K9YC On Sun,8/23/2015 6:48 PM, K5HM wrote: Anyone have any suggestions with regard to what favorite functions to assign to the P3 buttons.

Re: [Elecraft] KAT500 Utility
This is a tough one given that everyone else is likely running without issue. The common/obvious question: did you install as Administrator and are you running the utility as Administrator? Depending on resource requests from the program this can be a problem. Is the user you are running as an Administrator? If not, right click on the setup file and select “Run as Administrator”. Do the same when running the Utility. I just downloaded the latest utility and installed/ran without issue. This is Win10 x64, but I also run it on W7.

Re: [Elecraft] RJ-45 was K2.....
How many crimp tools? (accumulated partly for working jobs I had to supply my own tools) Two coax crimpers for RG58/RG59/RG174 - the one I use is ratcheted with replaceable dies One NAPA crimper for butt spices, spades, and ring connectors One RJ11/RJ45 Two Molex type 1.4 to 2.8mm One for 50-conductor computer cable and ribbon wire connectors One snap-ring plier at work I had a $500 Times Microwave coax crimper up to 1/2 inch (LMR-600) connectors. I do not use crimp-style at home; preferring the old back-nut clamp-style connector for N connectors. (retired so no access to this one) I do make RG58 and RG8x crimped N and BNC connectors (primarily shorter jumper cables). - From: brian als...@nc.rr.com To: elecraft@mailman.qth.net Subject: Re: [Elecraft] RJ-45 was K2.

I wonder who has the most crimp tool laying around and how many.
