[Elecraft] How to stop hearing amplifier relays at start of transmission?
On SSB, whenever I go to transmit (I use the PTT line) I can hear the distinct click of the amp relays at the start of my transmission. This is, if nothing else, embarrassing. I tried changing the TX DLY setting, but it seems that that setting only goes up to 20 ms, which is insufficient to stop the click from being audible. (Actually, it's not clear whether that setting even works in SSB mode; I assume that it does.) What setting can I use to increase the delay to something rather longer than 1/50 of a second? A quick calculation shows that anyone in a large-ish room and using an amp with loud relays is likely to have this problem. So there must be a solution, but what is it? Doc N7DR PS OT -- I thought I had posted this last week, but for some reason the reflector is now rejecting e-mails that comply with RFC 2440 and 3156, so I think it never appeared. webmaster@ (which is supposedly the address to which to send questions about the reflector) has not responded to my request for the rationale for this -- rather unusual -- decision. -- Web: http://www.sff.net/people/N7DR __ 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] K1 - 80m tx not working with wrong toroid for T4 transformer
Hello Lorenz and others, I have got the same problem on 80m with my recently assembled K1, sn#2919. The PA current was over 4amps for 5 watts RF output. I also burned the PA final Q7. After investigation, it turned out that wrong toroid was supplied for T4 with the kit. After replacing the toroid by a correct FT50-43 and a new PA 2SC1969 FOR Q7 the set was working perfect also on 80m. I will advise al owners of recently assembled K1 sets to check the type of the T4 toroid. With the wrong type the set is working on the higher bands, output is normal, but the PA current is higher than it should be as the efficiency of the PA is too low. The wrong toroid is complete black with a diameter of 11mm. The FT50-43 is black with one side dark grey and the diameter is 12,7mm. I know already from two other sets with the same problem. So there will be more around I suppose. At Elecraft they are aware of this. Hope this will help you and maybe others out of the problems. 73, Guido, ON6RL. -Oorspronkelijk bericht- Van: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] Namens Lorenz Koestler Verzonden: zondag 17 oktober 2010 22:39 Aan: Elecraft@mailman.qth.net Onderwerp: [Elecraft] K1 no output power Hi I build a K1 (80m, 20m) during the last days and had a lot of fun! The manual is just awesome and I am looking forward to make my first qso with it. Now I have a problem with the tramitter. That is why I joined this list and I was very glad to see, that there is much activity. The rx alignment went well and the resistance and voltage checks of the tx part are all fine. When I first started the tune mode on 80m with 2 watts, it shows me somewhat like 1.7, Q7 became quite hot and something started smelling. I was not able to read the current consumption before I disconnected the source. After double-checking all resistor values, the orientation of all diodes and ICs and the transformers, I tried it again. But now, regardless on what Out-Pwr and Band I choose, the display shows P0.1 in tune mode. I can hear a very weak tone in the K3 standing next to the K1. The current consumption is at about: 60mA rx, 200mA tx I cant see any cold solder connections nor bridges. So I guess I burned Q7 somehow. Any idea what I can do or what went wrong here? How can I test a 2SC1969 and what do I have to check, to make sure, I don't just burn a new one?

[Elecraft] RF Noise in the Neighborhood
Dear Electrafters, Perhaps off topic, I write for advice tackling a problem that plagues my K2 and QTH: overwhelming RF noise from a source I cannot identify. I've posted a screen shot of an o'scope trace of the IF output from a parlstar R30 showing the magnitude of this problem at the following URL. http://gegenschein.wordpress.com/2010/10/18/rf-noise-in-the-neighborhood/ So, I’ve been working on tracking down the source of this noise. Here is what I know: 1) Noise is persistent, but not always present. Perhaps present 90% of the time, with no pattern. When present, it is overwhelming. My K2 noise blanker cannot blank it reliably. 2) Noise - 120 Hz pulses - is present from AM broadcast band to about 20 MHz. 3) Source is not in my house. I’ve turned off the main circuit breaker and operated from battery — noise still overwhelming. 4) Noise is on the neighborhood power lines. 5) I cannot locate a single source of the noise (walking around with a portable radio); as noted above, it is on the main power lines in the hood. Please — any suggestions how I might track down this noise source and quiet it? I first started noticing the problem about 6 months ago and it has grown steadily worse. Now, I can't imagine how it could get worse. I am just waiting, now, for whatever is the source to final go up in a puff of smoke (or move out of the neighborhood).

Re: [Elecraft] RF Noise in the Neighborhood
Step 1: If it syncs on line as your RFI does, it is Power Line Interference. Call you local power company. They will have the instrumentation to locate the source and if it is their problem they will fix it. If it is a subscriber's problem they will most likely identify the source. Step 2. If step one fails then contact the RFI group at ARRL. Mike Gruber is on a first name basis with most of the utility companies and has a association with the FCC. The plan is, work with Mike and if all else fails then Mike will get the FCC involved. This type of interference can propogate over the power lines for quite some distance. in my case it turned out to be a bad GFCI outlet in my neighbor's garage. Changed the outlet and problem solved. 73s Jim, W4ATK On Oct 18, 2010, at 7:08 AM, Douglas Furton wrote: Dear Electrafters, Perhaps off topic, I write for advice tackling a problem that plagues my K2 and QTH: overwhelming RF noise from a source I cannot identify.

Re: [Elecraft] RF Noise in the Neighborhood
Went through this myself. S7 to S9 noise appeared out of nowhere and persistent almost 24 hours a day. I hunted for the source with no luck. Then it dawned on me the noise commenced while PECO (utility), Comcast and Verizon were doing upgrades in the neighborhood. All utilities are underground. PECO was convinced it wasn't them, but they sent someone out to check...No joy. However, when the upgrades were done (including the installation of new underground power lines and dog house transformers) the noise went awayWell kind of. The powerline noise was masking another noise source that was trashing everything from 80 up to 10m. This noise was about S5-7, but would cycle on an offon for about 40 seconds, off for about 20 seconds then back on. At first I thought it was some appliance on a timer, but that didn't make much sense. Not a furnace either. Eventually tracked it down to my neighbor's sodium vapor flood lights. These lights are notorious for generating interference when they are on their last legs. Had the rig on and observed his light flickering (noise present), going off (noise gone) and then coming back on (noise returned). Neighbor would not replace it until it eventually craped out. In the meantime, I used a Timewave ANC-4 and made a noise antenna (after some experimentation) that reduced the noise to about S1. Check the ARRL website as well as the eHAM Elmer forums. There is a link to a site with a dozen or more noise recordings that may be useful helping you narrow down the possible cause.

Re: [Elecraft] K3 VOX
Yes, this is the reason for using VOX to turn digital mode transmit on and off. Makes life in the real world of multiple simultaneous software applications much easier. I routinely run two instances of WSJT along with JT65-HF at the the same time. (I could try to run them all through LP-BRIDGE, except that it's just one more layer of complex code, and I know the main K-3 utility, K3-EZ, and (I think) K3 Frequency Memory Editor won't run reliably through LP-BRIDGE. VOX is just a simpler solution for digital.) LOL I operate both WSJT and SSB on 6 meters. Usually when I switch from WSJT mode to SSB mode (with the VOX on), my mic trips the transmitter a few times until I remember to shut off the VOX. One of the local 6m hams, who is ALWAYS monitoring 50125, keys his rig and coughs a couple times into his mic, just to needle me. This kind of teasing is innocuous enough, but I could sure do without it. :-/ When can we get independent VOX status for data modes and SSB? Assuming it's still on the list, how far down the list is it, Wayne?

[Elecraft] New Kenwood TS0-590
I finally got a chance to see the new Kenwood rig at HRO in Portland last Saturday. Didn't get to play with it for very long as there were too many others who wanted to play with it too. Anyway, it seems like a nice radio--sounded good--looks good--but still missing lots of things we get with a K3. It does seem like an obvious attempt to compete somewhat with the K3, but it's NOT a true contender for a lot of reasons. The ergonomics were fairly good, and unlike Yaesu, for example, they don't bury everything deep in a menu system. But you still have to push buttons a few extra times. For example, setting power level and keyer speed takes a couple of extra pushes of buttons vs. the K3. Like I said above, I didn't really get to play with it very long, but I'm certain you would be giving up a lot if you opted for this vs. a K3. The folks at Pacificon probably got a better chance to look at the new Kenwood. At least it shows that Kenwood is still in the amateur radio business, which I think is a good thing.

[Elecraft] K3, P3, other RS-232 Accessories and Baud Rate
I don't need a fix for this because mine is working now, but I thought I'd pass along what I did to correct my problem in case anyone else was having similar issues. Please don't send me an email to tell me I was an idiot and I should have known this, or to read this/that post. I just wanted to pass this along to possibly help someone else out. I have a K3 that connects to a MicroHam band-decoder and a Palstar AT-Auto tuner with a split RS-232 cable. The band-decoder also drives my remote antenna switches for one-click-and-everything-is-set for operation. I have a computer background and this set-up was completed about 2 years ago and has performed well at 4800 baud. When I put the P3 in the mix, the RS-232 communications between the devices started mis-behaving. The band-decoder would not know what band it was one and the AT-Auto tuner would start trying to tune for the wrong band. The K3 would change from 4800 to 38400 baud. I know the P3 and the K3 communicate at 38400, but I thought (and maybe I was wrong) that the K3, the accessories and the (output) RS-232 settings on the P3, should all be set at 4800 and everything should work. If I turned off the P3(but left it in line) everything would pass through and work properly at 4800. the K3 and P3 are at current/latest Firmware revisions. Anyway, Saturday, I set everything (K3, P3, Band-decoder, PC serial port and AT-Auto Tuner) to 38400 and everything is playing nicely and switching properly. Hopefully this may help someone with extra RS-232 gadgets like me. 73, Tad, WF4W What a long, strange trip it's been The Grateful Dead Truckin' __ 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

Believe me or not. The designer of TS590 also a K3 owner. He sure made some very questionable choices if he had a K3 to copy from! The TS-590 only uses the down conversion/roofing filter system on the 160, 80, 60, 40, 20 and 15 meter amateur bands! Outside those bands and above 21 MHz it is a conventional up conversion design. Why he chose to do what amounts to a complete second receiver from the antenna to the 24 KHz DSP last IF/demodulator is complete mystery.

Didn't get to play with it for very long as there were too many others who wanted to play with it too. Anyway, it seems like a nice radio--sounded good--looks good--but still missing lots of things we get with a K3. It does seem like an obvious attempt to compete somewhat with the K3, but it's NOT a true contender for a lot of reasons. The ergonomics were fairly good, and unlike Yaesu, for example, they don't bury everything deep in a menu system. But you still have to push buttons a few extra times. For example, setting power level and keyer speed takes a couple of extra pushes of buttons vs. the K3. Like I said above, I didn't really get to play with it very long, but I'm certain you would be giving up a lot if you opted for this vs. a K3. The folks at Pacificon probably got a better chance to look at the new Kenwood. At least it shows that Kenwood is still in the amateur radio business, which I think is a good thing.

[Elecraft] K3 MON feedback question
I thought I knew my K3s pretty well but I've got a simple issue that I can't seem to figure out so I thought I would toss it out to the crowd to see if you can clear my fog. There must be a simple setting that I've set incorrectly. I don't get on SSB very often but I'm trying to get ready for CQWW SSB soon and needed to go through this process of setting up the PC sound card for sending recorded messages. Problem: I can't use the MON on SSB because I get feedback (not the squealing type but the RF garbled sounding type) into my transmitted signal. When MON is set to zero, everything transmits perfectly, but, of course, I can't monitor my audio. Setup: Pair of K3s in SO2R with homebrew SO2R switching box. (The problem occurs with or without the SO2R box installed.) I use LINE IN for my recorded messages and my MIC is attached to the rear MIC input. My headphones are connected to the rear PHONES jack via the SO2R box. Sound card is the internal PC sound card of a DELL XP machine. MIC+LIN = ON. FW 4.06. KDVR3 installed but not used for contests. KRX3 installed but not involved in this problem (I don't think). It seems as if my headset microphone is picking up audio from the MON and dumping it into the MIC line, however, the speakers are OFF and I'm only using headphones. Since it can't be the speakers, I'm thinking I've got an open path between the MON and the MIC input but I'm not sure where that could be...inside the K3, on the PC sound card, etc.?

Re: [Elecraft] KPA 500
Not yet, but probably before year end. We want to see our final production parts price quotes and production parts lead times finalized before setting the price and order date. We also have to complete the FCC part 97 self certification submittal and get the subsequent approval. We are working on that now. That takes 30-60 days. For the FCC test data, there is nothing really difficult. We just have to present test data showing that the amp: 1. Has no more than 15 dB of gain. 2. Does not amplify between 26 and 28 MHz. (We use an internal freq counter for auto band switching to to handle this requirement.) 3. Meets the normal part 97 spurious levels for harmonics etc, which it easily exceeds. Plus we submit a bunch of additional docs, including a preliminary manual, block diagram, schematics etc. Lots of fun! :-) We'll certainly post here when we open it up for orders :-) We will not do that until we are confident of both the cost and the production ship date. 73, Eric www.elecraft.com On 10/18/2010 9:27 AM, Doug Faunt N6TQS +1-510-655-8604 wrote: So, when can we order one? 73, doug Date: Mon, 18 Oct 2010 09:24:19 -0700 From: Eric Swartz - WA6HHQ, Elecrafte...@elecraft.com We're shooting for first regular production in Feb.

Another forklift upgrade model enhancement path like the Alfred P. Sloan school of Product Management road map adopted over at Icom? Great way to keep up-selling radios to the masses!

Jon feels the K3 is a great SSB contest radio (!!!) but prefers the FTdx5000 for most uses. He feels the K3 RX is noisy. He also feels the TS590 is a great bang for the buck transceiver. I dont disagree. It might be nice to have a TS590 to replace my aging TS570 as a secondary radio. I always loved Kenwood ergonomics (except for the position of the dreaded MULTI knob on the TS570 that Kenwood moved on the 590!) all the way back to the TS820s. To each their own.

[Elecraft] Not Elecraft - AOR Proto AR7070
Hi all, Imagine… there are still people fiddling with “classic” conversion HF receivers ! Martein, PA3AKE, has just updated his web site to show the test results of the AR7070 up conversion radio. The AR7070 has been designed by John Thorpe the designer of the highly acclaimed AR7030 HF receiver and also the designer of the 'HF' series of receivers made in Matlock by Lowe Electronics in the late 1980s and early 1990s. IP3 dynamic range at 200Hz is 97 dB with an IP3 of 19dBm in a 2.4 KHz bandwidth. This rises to 115dBm at 50 KHz with IP3s around 46 dBm. The receiver has good sensitivity with no preamplifier before the first H mode mixer so for the 7Mhz band running with a 5 dB attenuator would put IP3 over 50dBm. Martein presents in tabular form all the performance measurements that have been made by John Thorpe the radio’s designer. There are also comments by Colin Horrabin, G3SBI and Martein. Basically this receiver is an up conversion CDG2000 receiver. To illustrate a particular point the AR7070 is compared with the review, by Peter Hart G3SJX, of the Yaesu FTDX5000 measured close in IP3 on the 7MHz band using the down conversion receiver. He did these tests with different roofing filter bandwidths. The test, using a 15 KHz wide filter, clearly showed that the IP3 within the roofing filter bandwidth was only -8.5 dBm. With the receiver noise figure being around 20 dB this gives a close in IP3 dynamic range of only 77dB compared to the AR7070s IP3 +19 dBm and 97 dB dynamic range in an SSB bandwidth. Take a look at the results and you will be surprised: http://www.xs4all.nl/~martein/pa3ake/hmode/ar7070-proto2.html It should prove to be the best up conversion radio of all time. 73 Gian I7SWX __ 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] VFO OFS
Hi Elecrafters I like the VFO OFS function for quick, large VFO A excursions very much. But I have to be so careful because it has happened a few times that while maneuvering VFO A and VFO B for delicate SPLIT settings, I accidentally bump the RIT knob and kepoi I have to start all over again. This is being plain clumsy but there might be a very elegant solution if the RIT knob could have a TAP= QSY feature similar the P3 'SELECT' knob.

I don't get on SSB very often but I'm trying to get ready for CQWW SSB soon and needed to go through this process of setting up the PC sound card for sending recorded messages. Problem: I can't use the MON on SSB because I get feedback (not the squealing type but the RF garbled sounding type) into my transmitted signal. When MON is set to zero, everything transmits perfectly, but, of course, I can't monitor my audio. Setup: Pair of K3s in SO2R with homebrew SO2R switching box.

It seems as if my headset microphone is picking up audio from the MON and dumping it into the MIC line, however, the speakers are OFF and I'm only using headphones. Since it can't be the speakers, I'm thinking I've got an open path between the MON and the MIC input but I'm not sure where that could be...inside the K3, on the PC sound card, etc.?

Should be easy to make a box with a switch to disable certain lines without having to disconnect the cable between the P3/K3. Maybe could be triggered by the Key Out signal, or just a simple toggle switch.

Re: [Elecraft] Elecraft at Pacificon, CA, Hamfest this weekend
Well, Dayton gets 20,000 people, Pacificon had maybe 2000. Not as large. I feel the forums are better at Pacificon, as they have more forums and rooms than Dayton. There are a lot of smart hams in the bay area that really support the forums. The commercial and flea market areas are not as large as Dayton. I am not sure if next year is the ARRL National at Pacificon or the year after. I arrived a bit late during the ARRL forum to catch that bit of data. When the show is the ARRL National convention, they bring the ARRL Expo, which I believe is the same as they setup at Dayton. Next year is the new larger hotel! I really like Pacificon, I go mainly for the forums to learn something new. I enjoyed Gordon West at breakfast - great way to start the morning, Cliff Stoll dinner speaker, moonbounce, WJST, 2M path to Hawaii, wG0AT and his goat adventures, and other great forums. Plus all day Friday's antenna forum for $10 is a bargain. I gave a talk on WSPR, filled the small room at 8 AM Sunday morning with about 35 people. Looking forward to next year, make your reservations early, as the hotel and special events typically sell out. Pacificon has become an annual three day event for me.

Re: [Elecraft] RF Noise in the Neighborhood
I Guys, I know how frustrating this can be. I had the same problem with a power line this last summer. You can have noise miles away off of a power line on the HF bands. Most utility company's have a department to track down RFI interference. They have equipment that will track it down to the insulator or bolt on a pole. Most PLC's Powerline Comminication have been installed for many years. Most PLC's are on mayor power lines and not on a normal over head line that is in the Neighborhood. Plus they only send a TX signal for Blocking and or Tripping. I understand if you have Internet over power lines, this can be a big problem. Call you utility company, they can help clean it up.

Re: [Elecraft] Re： New Kenwood TS0-590
Looks like I missed a few other tricks (not treats) in the TS-590. I refer the reader to Kenwood's own brochure for the TS-590 at: http://www.kenwoodusa.com/UserFiles/File/UnitedStates/Communications/AMA/Brochures/TS-590.pdf and their ad on the rear cover of QST for November 2010. The brochure and the manual are at odds about down-conversion on 60 meters. The manual (Specifications, pg 82) says the 5 MHz band uses down-conversion, the brochure (pg 3) omits 60 Meters in the list of bands that use down-conversion. Both sources and the ad are clear that down-conversion is not used when the receive bandwidth is more than 2.7 KHz (can you say ESSB), in AM or FM. Instead the rig switches to the conventional up-convert to VHF system. The brochure also makes another strange claim ... the TS-590 uses a bare DDS to drive the down-conversion mixer (pg 3) and claims that architecture is cleaner with less reciprocal mixing than a conventional PLL/VCO synthesizer. The brochure shows a picture of an Analog Devices AD9951 DDS ... I haven't checked recently but last I heard the Analog Devices and similar DDS products had some serious close-in spurs which resulted in poor wideband SFDR and *MORE* reciprocal mixing than a well designed PLL/VCO synthesizer, not less. Taken with the lack of a sub-receiver, no input for a separate receive antenna, no wideband IF for a panadapter, a 12V power amplifier, etc. the TS-590 is looking more and more like a warmed over TS-2000 with a gimmicky (partial) amateur bands only front end and not the serious, higher performance transceiver it was made out to be. When the serious testing begins, I hope independent engineers like Rob Sherwood, Peter Hart and the ARRL Labs will compare performance on 20 vs. 17 meters and check other issues like reciprocal mixing and IMDDR3 for *both* front ends. 73, ...

Anyway, it seems like a nice radio--sounded good--looks good--but still missing lots of things we get with a K3. It does seem like an obvious attempt to compete somewhat with the K3, but it's NOT a true contender for a lot of reasons. The ergonomics were fairly good, and unlike Yaesu, for example, they don't bury everything deep in a menu system. But you still have to push buttons a few extra times. For example, setting power level and keyer speed takes a couple of extra pushes of buttons vs. the K3. Like I said above, I didn't really get to play with it very long, but I'm certain you would be giving up a lot if you opted for this vs. a K3. The folks at Pacificon probably got a better chance to look at the new Kenwood. At least it shows that Kenwood is still in the amateur radio business, which I think is a good thing.

Re: [Elecraft] Re? New Kenwood TS0-590
Someone told me, when I was looking to buy my K3, that while the K3 was the top of the heap today, soon or later someone would come out with something equal or better. It's a competitive world. I am pleased that Kenwood is finally doing something decent in HF. I love my old TS-930s, a simple rig with great ears and a really great sound. My best guess is that new purchase decisions are going to be made according to priorities. The K3 will always be attractive because of its kit orientation and a lot of options for modifying and self servicing. Plus the K3 is constantly being improved and improvements are always passed on to the earlier models. The TS-930 will have some appeal because of price. The FTdx5000 is preferred by someone who wants a large box and lots of individual buttons and knobs, and who is already familiar with the FT series approach to controls. I still would like to see individual band and mode buttons. -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Lu Romero Sent: Monday, October 18, 2010 10:44 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Re?

Argument was that when the sunspot cycle peaks and especially with beam antennas that rigs with down conversion will suffer from image and IF rejection perhaps overload on 6-17m and that's why Kenwood chose that approach. More likely because: 1) the Kenwood DDS could not be made clean above 33 MHz or it might have been limited to 35 MHz (21.5 + 11.375 = 32.875 MHz). 2) Kenwood did not want to spend the money to design and build and align 10 (11 if you count 60 Meters) high performance filters necessary to cover each amateur band plus eight more high performance filters (ca. 4 MHz each) necessary to cover the spaces between bands. 3) Kenwood did not want to accept a hole in coverage around the 11.374 MHz first IF. By the way, the TS-590 is limited to two high performance roofing filters (2.7 KHz and 500 Hz). No option for additional filtering at other bandwidths ... they make up some BS about an advanced, level-optimized AGC even for signals that slip between the Roofing Filter and the final IF passband (brochure, page 3). 73, ...

What do you guys think Argument was that when the sunspot cycle peaks and especially with beam antennas that rigs with down conversion will suffer from image and IF rejection perhaps overload on 6-17m and that's why Kenwood chose that approach. If that were the case and signals that strong, looks like you could attenuate or rf gain. As far as the k3 is concerned, I've read it has extremely sharp bandpass filters for each band and I suppose that would help. And it has extremely good numbers on 14 MHz and 70db rejection on 50 Mhz and I assume it would be better on 28Mhz than 50Mhz would it not? Does this idea have any merit? I'm hoping to get my k3 by year end. Happy QSO'ing.

I don't understand the reason for the unusual conversion scheme. 73, Rob Sherwood, NC0B Joe Subich, W4TVli...@subich.com 10/18/2010 7:10 PM Looks like I missed a few other tricks (not treats) in the TS-590. I refer the reader to Kenwood's own brochure for the TS-590 at: http://www.kenwoodusa.com/UserFiles/File/UnitedStates/Communications/AMA/Brochures/TS-590.pdf and their ad on the rear cover of QST for November 2010. The brochure and the manual are at odds about down-conversion on 60 meters. The manual (Specifications, pg 82) says the 5 MHz band uses down-conversion, the brochure (pg 3) omits 60 Meters in the list of bands that use down-conversion. Both sources and the ad are clear that down-conversion is not used when the receive bandwidth is more than 2.7 KHz (can you say ESSB), in AM or FM. Instead the rig switches to the conventional up-convert to VHF system. The brochure also makes another strange claim ... the TS-590 uses a bare DDS to drive the down-conversion mixer (pg 3) and claims that architecture is cleaner with less reciprocal mixing than a conventional PLL/VCO synthesizer. The brochure shows a picture of an Analog Devices AD9951 DDS ... I haven't checked recently but last I heard the Analog Devices and similar DDS products had some serious close-in spurs which resulted in poor wideband SFDR and *MORE* reciprocal mixing than a well designed PLL/VCO synthesizer, not less. Taken with the lack of a sub-receiver, no input for a separate receive antenna, no wideband IF for a panadapter, a 12V power amplifier, etc. the TS-590 is looking more and more like a warmed over TS-2000 with a gimmicky (partial) amateur bands only front end and not the serious, higher performance transceiver it was made out to be. When the serious testing begins, I hope independent engineers like Rob Sherwood, Peter Hart and the ARRL Labs will compare performance on 20 vs. 17 meters and check other issues like reciprocal mixing and IMDDR3 for *both* front ends. 73, ...

He sure made some very questionable choices if he had a K3 to copy from! The TS-590 only uses the down conversion/roofing filter system on the 160, 80, 60, 40, 20 and 15 meter amateur bands! Outside those bands and above 21 MHz it is a conventional up conversion design. Why he chose to do what amounts to a complete second receiver from the antenna to the 24 KHz DSP last IF/demodulator is complete mystery. For essentially the same parts cost he could have included a second, lower performance receiver like the FT-5000. 73, ... Joe, W4TV On 10/18/2010 10:11 AM, Johnny Siu
Re: [Elecraft] K3/P3 - To watch own TX, what lines need to be disconnected?
The RS-232 cable between the P3 and the K3. You could make a box with a DPST switch or relay to open the TXD and RXD lines if you don't want to unplug the cable. On the other hand, how often do you adjust TX EQ? It would probably be easier just to unplug the cable than to build a switch box.

Should be easy to make a box with a switch to disable certain lines without having to disconnect the cable between the P3/K3. Maybe could be triggered by the Key Out signal, or just a simple toggle switch. Better still, add it to the P3, or offer it as a 'fungtion key'. ...bc __ 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 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] [K1, not K3] Toroid Problem and Other Comments
Guido wrote: ...it turned out that wrong toroid was supplied for T4 with the kit. ...At Elecraft they are aware of this. One would have thought that Elecraft should have issued a notice about a problem such as this which can cause real damage and waste great effort for troubleshooting if 80m use is attempted. At the very least it would be a sleeper problem silently reducing K1 efficiency on higher bands. (Disappointing.) I notice that after eight years a new revision of the K1 manual has been published...with the same incorrect info on the quick reference quide for the noise blanker that was noted on this list a decade ago! (Disappointing.) Hope this will help you and maybe others out of the problems. Yours is an excellent post. If my K1 had been subject to this problem, I'd have been most appreciative. Nine years ago I had a noise generation problem that was due to lack of RF bypassing in the noise blanker. I had to find out about the solution from a list member, for whom Elecraft had provided the solution. But enough...I've owned K1 #175 for ten years (waited five months for delivery) and it's still the finest QRP rig that I've ever owned. If I were in the market for another multi-band portable QRP rig, I'd have an order in for another K1. I prefer it (greatly) over the KX1 for a portable backpack rig. Even the KNB1 noise blanker, which for years I had a very lukewarm assessment, has turned out to be wonderfully effective on some sort of digital hum that affects 20m and 15m locally, as long as I use the HIGH threshold setting. (LO threshold setting introduces too much IMD and further reduces dynamic range.) I also like the capability of selecting iambic mode A or B on the K1. Most Japanese rigs do not allow selection of mode A, which is easier to use than mode B and just as fast. I'd have bought an ICOM 7000 years ago for mobile use, but ICOM designers are too stupid to figure out how to provide such simple but essential capability in a $1500 radio. Outfits like Jackson Harbor can design and sell a PIC that provides that capability in a DSW mono-band QRP kit...for $7! One more comment...the K1 LCD backlight. This is an excellent, even an essential, addition to the K1. But I found it damnably aggravating to install on an already assembled K1. The backlight SHOULD be a standard feature of the K1 because of the difficulty of backfit if it is desired later. If one orders a new K1 without backlight, a big mistake is being made!
