[Elecraft] Higher SWR When Using Amp.
I have noticed when I fired up my amplifier on 40 meters that the SWR reading on the K3 when I tune up is higher then when I tune up on standby. But what is really odd is on my External Wattmeter the SWR is the same when the amp is active versus standby. On standby my SWR on 40 meter SSB is 1.0 to 1. When I tune the Amp it goes up to 1.6 to 1. I realize that it isn't that high but just would like to know if there is an explanation as to why this occurs.

Re: [Elecraft] Higher SWR When Using Amp.
Mark, Where do you have your external wattmeter? On the output side of the amp? If so, then your external wattmeter and the K3 are reading the SWR of your antenna system when the amp is on standby. When you put the amplifier in-line, the K3 will read the input of the amplifier. In the meantime your external wattmeter is still reading the antenna system, and should not be expected to change. 73, Don W3FPR On 11/15/2010 6:43 AM, pastor...@verizon.net wrote: I have noticed when I fired up my amplifier on 40 meters that the SWR reading on the K3 when I tune up is higher then when I tune up on standby.

[Elecraft] HIGHER SWR WHEN AMP IS ON LINE
And Mark that means your amp tuned input circuit is not properly tuned to 50 ohms,that is why your K3 will see a higher swr when the amp is on line,you have two choices,one to enable the K3 builtin tuner if you have it installed,second tune the amp input circuit properly to let the K3 see a lower swr closer to 1.

[Elecraft] K3 LPF add-on filter
Good morning Elecrafters! It's been some time now since the K3 LPF add-on filter board was released. I've been contemplating purchasing one since its debut as I've noticed in the past hi-frequency DSP artifiacts, especially when listening with headphones. However, as time passed and firmware improved, I don't seem to hear so many of the things I thought I heard before. Perhaps my hearing has changed as well - who knows? So, with that said - what are people's opinions now on the LPF module? Is it still worth the purchase? Can a noticeable difference be heard, particularly on SSB with the filter installed? Finally, for those who performed the install themselves, what did you use to cut the two traces? Will a box cutter work or should I use a dremel cutting wheel?

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP
I had the chance to look at the FTDX5000's manual last night, as I was curious to see how the rig could be connected to a computer for digital modes. I had almost forgotten what a pain it was to hook up my FT840 to a PC, and I see with the FTDX5000, not much has changed. In order to connect to the computer and use something like DM780, one would need to purchase a separate TNC. I'm surprised that Yaesu still insisted on using a proprietary interface requiring a special connector. At least the new Icom's can pass rig commands and audio via their built-in USB ports. I would have assumed that Yaesu would have followed suit, but I guess not. It suddenly occurred to me how well designed the K3 really is, especially if one purchases the KIO3 module. No mess, no fuss, no external boxes and settings to deal with. It's as close to plug-and-play as one can get. All I needed to interface the K3 with my computer was 2 stereo cables for line in and line out, and an RS232 straight cable for rig control.

Re: [Elecraft] K3 LPF add-on filter
James, I recently installed the LPF myself. I cut the traces with my pocketknife. Nothing to it, just be careful. Soldering the filter was easy, after I cleaned up the via-holes. About the sound: The K3 sounds great with it. I THINK it sounds better than before (i use a heil headset). Proof for what it's worht: I find myself listening with the the headset more than before. (BTW, besides the headset I have two reasonable cheap Trust Soundwave Dynamic speakers for filling the shack with audio.) 73, Arie PA3A Op 15-11-2010 16:25, James Sarte schreef: --- So, with that said - what are people's opinions now on the LPF module?

Re: [Elecraft] Higher SWR When Using Amp.
Mark, when you tune your amp you are reading the input impedance of the amp SWR, not the antenna SWR. The only way that your external SWR meter and the transceiver SWR meter should match is if the external meter is between the amp and the transceiver. Even then, the SWR meters available to us are not precision instruments and are usually 5 to 10% of the max reading, so a 2kw watt meter could read 200 watts in error and still be in tolerance for an inexpensive meter. The better meters could be 100 watts in error, so the error can equal or exceed the output of the transceiver. If the 1.6 bothers you, you can adjust the input impedance matching circuit of the amplifier and perhaps reduce it, or you can activate your antenna tuner on your transceiver if you have one. You can also expect the SWR to change some as you tune your amp. If you have an old amp from the tube final days when the transceivers all had a pi network to match the amp, such as my Dentron Clipperton L, you may not even have an input matching circuit. I use the tuner in my K3 to match the input of the Clipperton. I don[t think you have anything to worry about.

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP
Thanks for pointing that out Joe. I should probably have used a better word. By proprietary, I was simply meaning that it's not as common an interface as an RS232 port, and two 3.5mm audio jacks. Almost everyone has stereo patch cables and perhaps a straight DB9 serial cable laying around. Not many might have a DIN 5 plug. At least I don't. :) 73, James K2QI On Mon, Nov 15, 2010 at 11:33 AM, Joe Subich, W4TV li...@subich.com wrote: I'm surprised that Yaesu still insisted on using a proprietary interface requiring a special connector.

Re: [Elecraft] K3 LPF add-on filter
Hi James, It's been some time since I bought and installed the LPF, and since it's not something you can put in and take out easily I can't comment on whether later firmware changes have reduced high frequency artifacts. The artifacts I was hearing back then were the aliased audio around the 12 kHz D/A clock, which the LPF pretty much knocked out. The difference when I installed the filter was subtle, but noticeable; I still have SOME hearing left in the 12 kHz range :-) I would say it's worth installing if either you hear the high frequency artifacts and they bother you, or you just want to keep your rig up-to-date with the latest mods, perhaps for resale reasons down the road. Installation is pretty straight forward. A sharp knife will do to cut the traces, I don't think you should get in there with a Dremel tool. One twitch and you could do a lot of damage. I used an Xacto knife with a new blade and it was almost disturbing how easily the traces were cut! 73 -- Joe KB8AP On Nov 15, 2010, at 7:25 AM, James Sarte wrote: Good morning Elecrafters!

[Elecraft] Still no tx or rx on new K3
Bob I had a similar experience for a few minutes during set-up of my new K3. In my case I had not installed a roofing filter at FL1, choosing instead to leave a gap there for later installation of a wider filter. The firmware default assumes a filter will be present at FL1 and the absence of one made the RX deaf and provided 0W RF out on TX. Once I had changed the default filter location, which I did using the Elecraft K3 utility, the RX came to life and TX Gain Cal ran just fine producing the required 5W output on every band. This might possibly be your problem. Good luck.

Once I had changed the default filter location, which I did using the Elecraft K3 utility, the RX came to life and TX Gain Cal ran just fine producing the required 5W output on every band. This might possibly be your problem. Good luck.

Re: [Elecraft] K3 APF
K3 ain't your daddy's analog radio... Incoming signals are handled as analog signals until they are converted to a 15 kHz IF. At that point the analog is converted to digital. All the rest is done in firmware as part of the number soup. Calling firmware functions IF or AF is really a misnomer. All the neat stuff is done BEFORE the number soup is converted to an actual AF voltage. APF number soup, NR digital soup, DSP number soup... I suppose you could say that some of the numbers were AF numbers and some of them were IF numbers? 73, Guy On Mon, Nov 15, 2010 at 11:19 AM, WILLIS COOKE wrco...@yahoo.com wrote: Igor, wouldn't you expect to find the Audio Peaking Filter in the Audio Frequency section?

Well, I would certainly hope that if one had the disposable income to buy an FTDX5000, he would also have the resources to take care of the family. My K3 was slightly north of $4k after all was said and done. To many others, that might seem exorbitant. Anyway, it's all relative. The important thing to keep in mind is priorities.

Re: [Elecraft] Higher SWR When Using Amp.
On 11/15/2010 3:43 AM, pastor...@verizon.net wrote: I have noticed when I fired up my amplifier on 40 meters that the SWR reading on the K3 when I tune up is higher then when I tune up on standby. When a rig drives an amp, it does not see the antenna, it sees the input circuit of the power amp. When the amp is in bypass mode (that is, not in the OPERATE mode), your rig DOES see the antenna. What you are seeing is some mismatch between the K3 and the power amp, which is the result of the input circuit of the power amp not being a perfect match to 50 ohms. This is QUITE NORMAL for most power amps. You should only worry about this if that SWR is much more than about 2:1. Most rigs, including the K3, will fold back (reduce power) to protect themselves if the SWR gets too high. As long as the K3 provides enough power to drive the amp to the desired output level, don't worry about it. With some amps, you can engage the K3's antenna tuner and tune it to provide a better match. That depends a bit on how the amp is being keyed. It is also common for the mismatch to vary from one band to another, and from one place on the band to another. In most power amps, the input circuit includes some form of bandpass filter. 73, Jim Brown 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

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP
Well, since I already took the XYL on a 2-week Alaskan cruise in August, I guess I'm good to go for the FT5000 :-) But I won't. I know I'm in the minority here, but if they took the second receiver out and lowered the cost accordingly, it would have more appeal. I appreciate the TX IMD, except that keying waveform and resulting spectrum sucks. I could do without the panadapter since the SDR-IQ as I use on the K3 suits my needs. The FT5000 size is more my cup of tea though. I'm old enough to remember when the first new car I bought (also a Pontiac) stickered at $1,800, so $6K for a radio sounds like a lot of dough. But that was before the $100 bill became the new twenty and it was then half a year's salary. To put things in perspective, I paid $2,200 for my TS-870 over 10 years ago and I still have it, and I wouldn't sell it for less than half that. So on a cost per year basis, it's not much. I don't play golf, so I'm entitled to at least one other indulgence.

[Elecraft] K3 rev 4.22 Beta Release: Improved APF (CW); all SSB anomalies fixed
K3 beta-test firmware revision 4.22 (with DSP rev. 2.70) is now available. This release includes our new APF (audio peaking filter) for CW mode. APF pitch is now tunable in 5-Hz steps, and the entire 200-1000 Hz pitch range is usable. For voice modes, the Fast Monitor and improved TX Noise Gate are now fully functional. All known issues with SSB power level have been corrected. See detailed release notes below. Please send any questions to k3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 4.22/DSP 2.70/FPF 1.14, 11-15-2010 NOTE: Be sure to install all firmware files for this release, including FPF 1.14. Otherwise your menu text will be incorrect. * APF (AUDIO PEAKING FILTER) ADDED: APF provides enhanced copy of weak signals in CW mode, and is especially useful when signals are at the noise level. The K3’s APF is patterned after the most successful analog APF implementations, and is equally effective in user tests. To use APF, make sure CONFIG:DUAL PB is set to APF. (This is the default. “NOR” restores the original DUAL PB function.) Then hold DUAL PB to turn APF on/off. A special DSP graphic display is used to show that APF is in effect. At the time APF is activated, the regular I.F. SHIFT setting, if any, is “frozen,” and SHIFT then controls the center pitch of the APF filter in 5-Hz steps. APF is independent for the main and sub receivers, as well as for presets I and II. Switching between these two presets is a convenient way of turning APF on/off quickly. * ADDED VOICE TX “FAST MONITOR”: Normally the voice monitor includes a ~20-ms delay, which is necessary to hear how your on-air signal will sound (with compression, etc.). If you prefer to not hear any delay in the voice monitor, set CONFIG:TX MON to FAST. Note: You’ll still hear the delayed and processed monitor if you adjust the MIC, CMP, TX EQ or TX GATE settings while transmitting. * TX NOISE GATE IMPROVEMENT: The Noise Gate/Downward Expander for voice modes has smoother response and much improved performance near the threshold. * NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT and WIDTH when using very narrow DSP filters no longer causes ‘pop’ artifacts. * SSB reduced power level bug fixed: Error was introduced in DSP 2.65. * FSK-D PSK-D bug fixed: In DSP 2.69, there was no monitor for these modes if CONFIG:TX MON was set to FAST. __ 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] Some bands and modes are always upconversion on the TS-590
I am sure that they were all design trade-offs made to get the radio to meet a certain market price point. The question is how much bang do you get for the buck? Is a K-3 worth the (nominal) $1,200 more ? To us, the answer is yes. To others, the improvement seen in the receiver may not be worth the extra money given the manner is which they operate. Also, there are plenty of hams that can just not afford a $3,000.00 + radio no matter how good it is, and the Kenwood gives them a nice rig for the price point.

Re: [Elecraft] K3 LPF add-on filter

I didn't hear anything back, which is just as well, cuz I like the firmware version as much, or better, than anything I've cobbled up g. In any case, if you download the K3 LPF add-on filter manual and study the schematic, you can experiment with your own low-level active or passive APFs using the cuts as in and out, if you choose. Just bring the connections out of the radio in shielded cable.

Re: [Elecraft] Fwd: FT5000 PIN Diodes
Hi Karl, I think there are a few issues to clear up here. The K3 uses PIN diodes that are rated down to around 500 kHz, so they won't cause any IMD due to broadcast band signals. Such PIN diodes are readily available, but more expensive, so I can see why a manufacturer might want to use relay switching instead. That wasn't an option in the K3 -- it had to have solid-state T/R switching. In addition to using the right PIN diodes, we took two extra precautions. First, we incorporated a high-pass filter into the T/R switch. It rolls off signals below 1 MHz to ensure that extremely strong signals in the 500 kHz range or below are attenuated. The attenuation at 500 kHz is about 20-25 dB. This is not a problem for casual broadcast band DXing. However, we also provide a way around the T/R switch: the RX ANT IN jack on the KXV3 or KXV3A module. Most broadcast-band enthusiasts connect their low-band receiving antenna directly to RX ANT IN, bypassing the high-pass filter. If you still have a particular station that's a problem, you could use an external notch filter in line with RX ANT IN. 73, Wayne N6KR On Nov 15, 2010, at 3:33 PM, Karl Marderian wrote: Sent from my iPhone Begin forwarded message: From: Karl Marderian karl...@sbcglobal.net Date: November 15, 2010 3:23:33 PM PST To: elecr...@mailman.gth.net elecr...@mailman.gth.net Subject: FT5000 PIN Diodes As I remember, when I bought my K3.

Re: [Elecraft] K2/100 QSK problem
Jim, No relays are involved in the K2 T/R switching, it is all solid state and it is quite fast. I could surmise that your problem occurs after a band change or right after a power cycle or after a change in the requested power. In cases like that, the K2 will drop the power to a low value and build up to the requested level after a dot or two - the DX station may not be hearing the dots at lower power. To avoid that initial power leveling situation, you would have to transmit a few dots before your callsign. OTOH, if that happens consistently (and not after a band change or change of power), then you should check further. 73, Don W3FPR On 11/15/2010 6:45 PM, k2z...@aol.com wrote: Upon initial power up OR after the K2 has been idle for a short period of time I have discovered that the first character keyed gets truncated.

[Elecraft] I like the modular design (was: OT: QST's review of the Yaesu FTDX5000MP)
Hello George, I have recently purchased a second hand K3 and discovered the KPA3 was not working. Since K3 is modular design, I simply sent the problematic KPA3 back for repair. Modular design is good for overseas user like myself. A modular design is workable as long as majority of the users, Elecrafters, have some technical knowledge (all of us passed the radio amateur examination). Or, the users, like the Elecrafters here, at least border to look into the radio. For commercial / institutional radios, when there are causal users not so technical oriented or simply don't have the luxury of time, the approach in K3 may have to be carefulluy considered. For most commercial radio manufacturers, I suppose they have to comply all the ISO (i.e. ISO 9000, 9001, 9002) requirements. Manufacturers will possibly be worried about whether plug out / plug in modules will affect the performance of the radios under those ISO requirements. On the other hand, extensive support service (like Elecraft) has to be provided to cope with all those updates and exchange / replacement of modules / PCB. Elecraft is doing very well now. However, how about if Elecraft's sales volume like the Icom, Yaesu and Kenwood (I think Wayne and Eric would like to have that sales volume), extensive support service could be a burden from business point of view. I shall be back on the air again with K3 upon finish repair of the KPA3. cheers, Johnny VR2XMC - 郵件原件 寄件人﹕ George A.

I've programmed the N1MM macros from N6ML's site http://www.dseven.org/ar/n1mm-kdvr3 to drive the K3 DVR and they work great when pushing the physical N1MM Function keys or clicking same on-screen. BUT, when using VOX, I've discovered that the message won't play if I try to start it (with the N1MM F-key or ENTER in ESM mode) while the PTT is still asserted from my earlier speaking. If I wait that fraction of a second until the VOX PTT drops (i.e., when I hear noise in the headset again) before I initiate the message, it plays fine. Switching to the footswitch instead of VOX, everything plays fine even if I keep the footswitch down while the DVR message is starting. Seems like the same logic in the K3 that allows that should also apply to the VOX PTT assertion, but apparently it does not? Is this expected behavior or maybe a bug or needed enhancement in the DVR? 2. I find that the playback level of the DVR is a function of the MIC GAIN setting when recording. In other words, changing the MIC gain during playback does NOT affect then playback level. However, the DVR evidently stores UNCOMPRESSED audio because the compression DOES vary directly with the COMP control during DVR playback. Again, is this normal/expected? With all due respect, I LOVE my K3, but I HATE having to experiment (or read this reflector) to learn things like this when it SHOULD be in the manual. Frankly, IMHO, the K3 manual stinks.

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP
What would bother me about this kind of a rig is that after spending all that money on it, I may find myself owning an outmoded rig in a couple of years. They only maintain the current state of the art up to a point, then they want to sell a new model. I would be extremely mad if I had bought the FT-2000 and now find the FT-5000 offering significantly enhanced performance. Why would you be mad if you bought an FT-2000 and then Yaesu comes out with the FT-5000 with significantly better performance? It costs twice as much, it'd better have significantly better performance.

Again the K3 is for the HAM that whats to design his own radio.I have little or no use for a sub receiver. Others may not only want, but need one. I like making it the way I want it to be and not pay more. Give me some lottery winnings and I would love to have a FT5000. Again we the HAMS win when stuff gets better and better.

Hello, For those of us who have two K3's and two W2 Watt meters, would you consider one of two options to help us know which interface we are looking at? 1) Since one has to rename the Interface executable to run two copies at the same time, perhaps in the load event of the main form, put code that changes the form Text (Title) to the name the W2 executable started up with. 2) In the setup form add a TextBox control that allows the user enter Text they would like to display in the form Text (Title).

[Elecraft] Unstable KPA3-100W
I got a number of reports from SS CW of spurious signals. I have isolated it to one K3 (S/N 4498). With the KPA3-100 disabled (below 12 watts) the signal is clean. From about 13 watts to 90 watts, there are spurious signals about every 1KHz + and - the carrier frequency. The frequency of the spurs changes as the power control is advanced and the signal becomes clean again at about 90W. This happens on 80, 20 and 10 (the only bands this radio has antennas for). Also, the power output is unstable on the wattmeter and the SWR apparently changes continually indicating a wandering spur. Any ideas?

[Elecraft] OT: Problems with Icom 756 Pro III internal tuner
Greetings fellow Elecrafters, I'm sorry for emailing this question to the group, but the folks on this reflector are a smart bunch. Maybe someone could give me some advice or suggestions. I posted this question to the Icom 756 Pro III group and QRZ, but no one seems to have an answer. I'm diagnosing a problem with an Icom 756 Pro III. It's tuner's insertion loss is quite high. For example, when the tuner is off, sending an unmodulated FSK carrier shows the transceiver putting out 100W. As soon as the tuner is activated, power drops by 10-15%. That's a lot of power being dissipated somewhere, and I don't think it's good especially for 100% duty cycle modes. It doesn't matter whether the Icom is connected to a dummy load or resonant antenna. The results are always the same on every band. In comparison, the K3's tuner seems to be incredibly efficient. If there is a loss of output power on the K3 whenever its tuner is inline, it's not noticeable. More often than not, power increases when the K3 finds a good impedence match. I've gone as far as recalibrating the Icom's tuner. This was done by terminating the remote jack on the rear panel, and entering the tuner service mode. The tuner calibration process completed with no errors reported by the Pro3. Any suggestions? I'm going to call Icom support tomorrow to see what they say. - 73 de James K2QI President UNARC/4U1UN __ 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] OT: QST's review of the Yaesu FTDX5000MP
Joe: Ahhh, Product Marketing/Management. I miss it so. :) Very bad design with slick marketing. You mean it was designed by Sony Broadcast? :) Your points are dead on. But I think there is more. It may be that in the next two years, they will be able to offer you the upgraded TS590S(G) with a real dual receiver system and quality IF filters, or they will bail from the market altogether. Successful patterns are repeated in Product Marketing. This looks to me like a stalling tactic while working on proving market segment competitiveness to help make a decision; continue to play or fold? More than likely, funds were limited because they were starved for product development resources while merging with JVC, and Corporate wants better data to see if the Amateur Radio market makes sense, so they chose to stay with the basic TS570 platform and enhance it much in the same way Betacam became BetacamSP (some added signals here, some metal tape there. Presto!). Good Marketing will take care of the rest! We build Legends is performance by association from the era when there were resources for product line development and RD. There's still a lot of Goodwill from the TS950/TS850 days! Even from TS520 days! And Larry, you're right, from a technical perspective, the 590 receiver schema is really Goofy! But they will sell a ton of them, as will Ten Tec with the Eagle, which is the 590's true competitor IMHO! Then there is the Icom Behemoth. I still think that all the Icom Marketing folks are disciples of Alfred P. Sloan. Their product line looks exactly like General Motors in the late 60's early 70's. Products from Cradle to Grave, with a sports car and some trucks thrown in for good measure! Elecraft's well targeted market niche is being attacked from above by the FTdx5k and from below by the 590 and to a lesser extent, the Eagle. Most of the erosion will be in the lower side of the equation. Main K3 competitor is really the IC7600, and technically it leaves a lot to be desired and is not as customizable, but undercuts K3 in price and it has the Icom mystique by association. Icom has done a masterful job at brand identity. So the K3 niche is still rather exclusive, but eroding a little bit. Frankly, Yaesu has just cannibalized the FTdx9k product line AFAIC! That platform is a dead end now and must be awfully expensive to continue to market, so I expect for it to quietly fade away. Elecraft is a lot like Honda in the mid 70's. Pick the niche, build a solid product and back it with uncompromising service, winning one customer at a time. -lu-w4lt- K3 # 3192 -- Message: 29 Date: Mon, 15 Nov 2010 17:13:35 -0500 From: Joe Subich, W4TV li...@subich.com Subject: Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP To: elecraft@mailman.qth.net Message-ID: 4ce1b08f.1050...@subich.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed That makes absolutely no sense to me.
