Re: [Elecraft] Very Dissatisfied With Elecraft Support
Jon, I haven't read all the replies on this list, it's getting late here in California, so I hope I'm not being repetitious. From what I read it sounds like you are having a rather normal experience. I don't know how old you are, so I can't tell if this will be very helpful. Usually I can guess from the call sign, but a KB1 that's only a couple months old is a little difficult to 'decode.' Anyway, I wanted to tell you that I am a retired engineer who is teaching electronics at the local high school. I have actually been teaching part time for the last 23 years, partly for my own fun and partly to help make sure some of our youth gets more out of high school than most schools offer. If you were living in Santa Barbara, I can guarantee you wouldn't be having this problem. Our local school district offers the classes I teach absolutely free of charge and there is no age restriction except we prefer students be over 15. ( I have several 9th graders that are barely 14 and several adults in their 40s.) We offer the training along with the books and online resources, and every imaginable test equipment you could need. My class just completed a K2 10 Watt transceiver, and their antenna is going up tomorrow. I suggest you get in touch with your local school district/community college and local ham clubs. You may have had some contact with a local club already. In fact the ARRL headquarters and their entire lab is only a short drive (~69Mi) away from Stamford, where you live. And be sure to take your K1 with you. Take an adult ed class, maybe. Hams are one of the greatest 'fraternities' I know of. Look at all the replies you got on this list! We've all been through this and we rely on each other, most of us can't afford a lot of test gear, etc. either. So, we share with each other. Oh, yes! One other thing - don't be too hard on the Elecraft support people. After all, this list is their idea. Plus, they have don't a super human job of putting a new product on the market this past year and it may have them spread a little thin. What you have received from them isn't available from most companies at any level. Good Luck, let us know how you make out. (Even experienced builders have had problems getting as far as you have).

Re: [Elecraft] K2 - KIO2 stop bit oddity
The receiver's stop-bit setting needs to be greater than or equal to the stop bit setting of the transmitter. It is OK for the transmitter to You meant less than, not greater than, although, as you noted later, receivers generally don't have a stop bits setting. Yes. send two stop bits and for the receiver to be set for one stop bit. It won't hurt a thing. Most UARTs use the stop bit setting to affect only the transmitter (RS-232 sending part of the device). The receiver will Delete RS232. (In fact, historically, current loop was used for the physical interface.) True, once the mechanical teleprinters fell from grace, current loop fell by the wayside. (Unless you were connecting to DEC hardware. I have implemented more than one 20mA current loop to RS-232 converter in my life.) handle anything that is at least one bit-time long for a stop bit. Modern UARTs accept stop bits that are just over half a signalling unit in length (they sample in the nominal middle, but there is a limited sampling clock resolution. They need to accept ones that are strictly shorter than the transmitted ones, because, as we are talking about asynchronous signalling, they need to be able to cope with recovering from false start bits and cope with clock rate differences (more common on mechanical devices, but some electronic devices rely on these to allow working with convenient crystals. (When sending asynchronous data over 1200 bps synchronous modems, sometimes no stop bits could be sent over the wire, if the source clock was fast, as, being synchronous, there was no option to shorten the stop bit. Stop bits were re-inserted before creating the baseband output; I believe they ran the output clock fast to ensure that this worked.) You are, of course, correct. I should make sure that I am rigidly correct when I write and I was being sloppy. Having implemented UARTs in both software and hardware, and then the protocols to run over them (I am one of the authors of PPP and the architect for MLPPP) I do have a modicum of understanding. Longer stop bits just reduce the maximum rate (characters per second) that you can send data. And give better recovery from false start bits - not a problem you should have on a short piece of wire. Incidentally, 4800 baud is normally sent with one stop bit. As noted elsewhere, it is only really for mechanical devices that one needed longer ones, so it tends to be 110 and below (maybe 300) that uses 2, or for, 5 unit, Baudot, 1.5. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Very Dissatisfied With Elecraft Support
I can understand your frustration, but there may be a simplier solution. The K2 comes with the parts to make a simple RF probe: 1N34A diode, .01 uf cap, 47 M ohm resistor and a length of RG-174 coax. You should be able to order all of the parts from Elecraft, including the small PC board that is used - part number E100079 (it's also used as a spacing tool for mounting the front panel switches). The instructions are on page 9 of Appendix E in the K2 manual that can be downloaded from the Elecraft web site. For that matter, someone who has already built their K2 and used a 'scope instead of the RF probe probably has all the bits lying around and would send them to Jon if he asked. -- 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

IMO one area where the IC-7700 and co. win out is in ergonomics, especially for those of us who are members of the Terminally Bewildered club (tired eyes, colour blindness). Given the extra real estate this may seem like a daft comparison, but the FTDX-9000's tuning knob(s) and the IC-7700 / IC-7800 display are excellent.

In the intense QRM conditions of RTTY contesting in Europe, I routinely use two cascaded 250Hz filters at 8215kHz and 455kHz in the 1000MP. (Unfortunately the new Inrad website doesn't include filter plots, so it isn't possible to estimate the cumulative bandwidths of these cascaded filters.) When the channel is clear, copy of weak signals is not noticeably degraded compared with cascaded 500Hz filters; but when QRM appears, the narrower filters often make a decisive difference by preventing a strong unwanted tone from capturing the AGC. A 200Hz 5-pole filter for the K3 is arriving next week, and then I'll be able to do some A/B/C testing against the K3's own 400Hz filter and the 250+250 filters in the MP. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Shipping to UK
I'd be grateful for any feedback from UK amateurs as to their experiences with the various shipping options.

[Elecraft] K3: Comparison to Big Guns
The K3 has a different receiver design. Its first IF is 8,215 Mhz while the IC-7700, IC7800 has an IF that is near 75 Mhz. The result is that roofing filters can be built for 8,215 Mhz that have smaller and pass, since trying to build a 200-500 cycle filter for the higher freq is impossible or extremely expensive using current technology. SO... the design of the K3 and Orion allow the roofing filters that are key to their performance. The higher first IF used in the Icom rigs has an advantage of fewer images. That is their key disign criteria, rather than a sharp roofing filter. As a result, I would say the K3 is the performance choice for CW and digital, where as the Icom rigs with all the bells and whistles are the SSB operator's dream. It sure is pretty'!

However, whatever you are ordering it is probably worth paying the extra for UPS anyway unless you are willing to be very patient. My eagerly awaited KPA was despatched from Aptos on 8th May and I am still waiting for it! It took 3 days to reach British customs, the bureaucrats took 4 days to decide how much money I have to give our useless government to squander, so it left customs yesterday evening. Now it all depends on whether Parcel Farce manages to lose it or not. Incidentally the KK7UQ IMD meter I ordered at the same time as the KPA was shipped by US Interface in an official USPS cardboard mailer and took only 4 days to arrive.

[Elecraft] K2 SSB Watery Audio Distortion
There has always been some watery distortion on my SSB signal from my K2/100. It is there with or without the KPA100. It is there with three different mikes. It is there with two different KSB2 modules. It is there on both upper and lower sideband. The CW signal sounds pretty good, no obvious problem. The SSB distortion is not real bad, but noticeable. The ALC is high and has a hard time settling down on 80M. It settles to two bars but may start at 6 or 7 bars. The ALC on 10M is just one bar. The watery distortion is on all bands 80M thru 10M and into a dummy load. I assume the problem is not KPA100, KSB2, mikes, or RF getting in. The problem has been there for years (sn 3194) but has worked it's way up the fix list. At this point I'm not sure where to start.

RE: [Elecraft] The K3 in comparison to the Big Guns
I've been following the 'big gun' thread with interest. I'm astonished that this group seems to imply that 'big gun' status depends upon the radio you own, rather than the amplifiers and antennas you use. Most rigs today put out between 100-200 watts, regardless of price. DX'ing and contesting success seems to me to be related to your amplifier and your antennas, not your radio. The radio only comes into play on the low bands, where being able to hear the weak ones through the noise becomes important. All this begs the question, Who is a 'big gun'? Is it someone with a 5 figure radio, someone who breaks all the pile-ups with one call, someone who wins all of the contests, someone who is on top of the Honor Roll and has 5BWAZ, or someone who has 160 acres of antenna farm with full wavelength beverages every 22.5 degrees? Maybe it's all of the above, but I doubt it. I'm a little pistol by most definitions, but I'm #1 Honor Roll, have 2507 band-entities toward the Challenge, and hold the WPX Award of Excellence endorsed for 160, 30, 17, 12, and digital modes. I lack 8 entities on 160 for 9BDXCC, lack 6 zones for 5BWAZ. I've been DX'ing since 1981, and I use an FT-100 (FT-707 before that), 600 watts of amplifier power, a TH-11 at 48 ft. (since 1996, a HF6V before that), a side mounted 5 element yagi on 6 meters, and a HF2V with 30 meter coil. I have a flag, mag loop, and low 80 meter dipole to help me hear better on 160. My entire antenna farm is crammed into a back yard in town that measures 60x70 ft. So why did I order a K3? Because I can't hear the DX very well on 80 and 160, and I'm betting that the K3 will enable me to improve my low band Challenge score and finish 5BWAZ from my sub-optimal location. Besides, I'm retiring, and it's time for my dream radio. Maybe 'big gun' is more about what you do than what you have, but I'm really looking forward to my K3.

Re: [Elecraft] K2 SSB Watery Audio Distortion
John, You said it is there with and without the KPA100. Have you physically removed the KPA100 and tried it with just the base K2? If not, please try that. Should the base K2 be clean, re-install the KPA100, but after it is installed, remove the right side panel and fold/tuck the ribbon cable and the speaker cable into the area near where the ribbon cable attaches to the control board. Often such a watery sound is caused by coupling from the ribbon or speaker back into the KSB2 board - dressing the ribbon and speaker cables away from the KSB2 fixes it. That is at least a starting point. 73, Don W3FPR John Huffman wrote: There has always been some watery distortion on my SSB signal from my K2/100. It is there with or without the KPA100.

Re: [Elecraft] K2 SSB Watery Audio Distortion
Hello John If you have another ssb receiver available that can tune to the K2 IF frequency, try listening to ssb directly out of the KSB2 and see if it is watery there. If not, the problem lies elsewhere in the rig. If it is watery, which I doubt it will be, since you say you get the same result with two different KSB2 modules, then the problem may be in the KSB2s. Also check the stability of the oscillators by listening to them. Is there any warble at all in their frequencies?

[Elecraft] (no subject)
I can not say that the specs prove the 7700 is better or worse overall as a SSB rig. I think it is clear that for CW contesting, the K3 has better specs. The 7700 seems aimed at the comfortable arm chair, brandy in hand, cuban cigar, imprepressive setup with a 30 display, let me tweak my audio a bit, you are always 5x9 here, it looks good on the scope, am I wide enough -- approach to hamming. It is surely a rig with great style and feel, and by the way also a world class performer. On the other hand the K3 is the sports car that can be stripped down simple, or you can add the performance packages -- but at its core is high performance. Frills second, performance first.

That's exactly what I was thinking, and was wondering why in the scores of earlier replies there had been no suggestion of this. The RF probe won't solve this very likely cause! Jon, see if you can find a local ham who has a receiver that can copy 22.000 MHz and get your K1 next to that receiver. When 20m is selected on your K1, you should be able to hear the 20m filter board heterodyne crystal signal strongly in the other receiver if a piece of wire laying near your filter board is input to the other receiver's antenna connection. The signal should likely be found around 21.995 to 22.005 MHz. If you hear nothing, then the crystal is not working. If this is not possible, get Elecraft to send another 22 MHz crystal and swap it in (easter-egg it). Elecraft support is, in fact, of the highest order and not matched by many other ham radio merchants. The K1 is a fantastic little rig...my favorite QRP rig of all time. I would have suggested buying the four-band filter board instead of the two-band, because not only does it double the bands but it does so with much sharper RF filtering than is found in the two-band board. At least you'll be able to upgrade later when you find out what a gem the K1 is, and maybe re-build your two-band board for bands the four-band board doesn't cover. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] The K3 in comprison to the Big Guns
The experts will weigh in better than I. One can buy an Escalade or one can buy a Tahoe. The Escalade has more bells and whistles, but doesn't drive better or haul more than a Tahoe. The 7800/FTdx9000 have something for everyone. A knob for every function (or nearly). What they also have is an upconversion receiver, which is where the difference in receiver performance begins. It is not yet possible to make narrowband multipole filters at VHF that are as good as narrowband multipole filters at the K3 8MHz first IF, that the amateur community wants to afford. That is why the narrowest 7800 first IF filter is (if memory serves) 3KHz. So the K3 starts out with a huge filter advantage because its first IF filter can go to whatever is available, like 250Hz. (I avoid the term 'roofing filter' to honor Wayne's preferences.) The remainder of the K3 receiver front end advantage, i.e. inside the 1st IF filter specs, is the result of what Wayne wants in a radio. He's been designing stout front ends as long as I've known him coming up on 20 years. The competition makes their design compromises in accordance with objectives, cost effectiveness (i.e. good enough for who its for) etc. while the K3 design seems to lean toward no compromise in performance. I note that the 7800 first appeared with something like a 6KHz first IF filter, got hammered in the press, eham etc. for lousy close-in performance, and quickly added a 3KHz 1st IF filter option. Some of the K3 front end specs are up there near the very top line spectrum and network analyzers from industry luminaries like Rohde-Schwarz, Agilent etc. which cost $50,000 to start (that's like the base K3), running up towards a quarter million with decent options. Not to say the very expensive radios are not good. They are, and they fit well in the livingroom entertainment system as well. Whereas the K3's appearance is more attuned to 'the shack' or the backpack, a utilitarian tool. Let's not forget Wayne is first and foremost a QRP backpacker. The 10 watt K3 version is surely the very highest performance rig serving the portable market, and fortunately the DX/contest market as well. Plus one can buy 3 or 4 K3's for the price of a livingroom appliance (lest I get hammered on the appliance remark, I happily owned a IC781 for many years). I do hope I haven't said something stupid here. If so, it's all my fault. 73 Art Snip Shane wrote: Message: 7 Date: Thu, 15 May 2008 21:06:15 -0700 (PDT) From: Shane White [EMAIL PROTECTED] Subject: [Elecraft] The K3 in comprison to the Big Guns To: elecraft@mailman.qth.net Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=us-ascii That's it, I'm going to ask the silly question.

Hi Don, The temperance and helpfulness that you and all the other list members extend to help solve a frustrating problem makes this list a great part of the Elecraft package that enables folks to get their gear going. I was thinking, after Jon mentioned joining a local ham club, that it would likely be simpler and quicker to find a ham with the appropriate receiver to check this. Even a RF probe is not as iron-clad a device for detecting this problem, but if an RF probe only were to be employed for troubleshooting this would be the first place to look for a problem. I believe that the eight-year history of the K1 shows there to be no more likely cause of K1 20m band problems (on either the two-band or four-band boards) than the failure of the 22 MHz heterodyne crystal before installation, or its premature death afterwards. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Shields - Theory of Operation?
Naïve question... I'm looking at the shields on the inside of my K3 (the one that separates the RF compartment from the front panel, and the one that segregates the KPA3 from the rest of the system), and I'm wondering why they work :-) My questions fall into three areas: 1) These shields are full of holes and slots. For example, the KPA shield has big rectangular cutouts where material was folded down to make the tabs that the board mounts onto. It also has a 1-2mm slot along the bottom left edge (close to the key and paddle connectors). The front panel shield has holes where the tabs were formed in the upper corners to mount to the 2D connectors, and slots for clearance around the connectors that pass through to the front panel board from the RF board in the lower corners. Why don't these slots allow unacceptable RF leakage? Are they just too small at these frequencies? 2) The PC board forms the bottom of the shield box in both cases. Yet the shields aren't connected electrically to the boards. Doesn't this make the interior of the PCB itself a big slot antenna where the bottom of the shield runs along the board? Does the board have a solid enough ground plane that it provides a good bottom for the shield? 3) The connectors that pass through the shields, especially the ones that pass through the front panel shield, don't appear to be RF proofed in any way. They don't use pass-through caps or anything - there is just a big hold in the shield with the connector sticking through it. Why does this work? I'm asking because I'm considering homebrewing some stuff that would require separation between the RF area and the PIC microcontroller area, and I'm trying to learn from the K3's obviously excellent design.

[Elecraft] A new perspective
Hi all, it's been awhile since I last posted to the reflector. There has been quite a bit of noise out there about disatifaction with Elecraft Support. Now I can sympathise with anyone who is experiencing problems with building rigs. Over a year ago I managed to wreck Two (2) perfectly good K2s - due to lack of knowledge, skill and proper tools/equipment, and most of all lack of patience. Boo - hoo me! My impatience and desire to have the perfect rig took over and disaster resulted. Sure it hurt at the time, but I assigned all the blame to myself and have moved on. For the past year now I have regrouped, retooled and adapted a more rational attitude toward Amateur Radio. Iv'e managed to build a few simpler rigs from various companies and have also put together some accessories for the shack. My soldering annd building skills have greatly improved and I have gained more knowledge, Most of all I have learned patience. I'm still young (53) and have at least a couple of solar maximums left. Maybe next year I'll build that k2 (or K3 hi! hi!) But what is really important for me is that I am still greatly satisified with Amateur Radio, and for that matter Elecraft Inc. Just recently I got 2 people interested in this hobby.I have also rediscovered the fun of operating portable QRP in the field. Just do something constructive instead of dwelling upon the negative.Group therapy might help.So ADAPT A NEW PERSPECTIVE. Elecraft is a good company. I like what they do. And I will continue to be a satisified customer. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] The K3 in comparison to the Big Guns
Modern radios do malfunction in such a way that repair of them is likely beyond the capability of most owners, unless the radio came from Elecraft. Should such an event occur with your radio, would you rather pack and ship back to the factory a brick (Icom, etc), or a feather (A K3 module). The heaviest K3 module is probably less than 2 pounds, and the Elecraft guys at Aptos can tell you which one is bad, based on the symptoms you describe. I cannot imagine a problem which would require the return of my entire K3. I recently had a minor (not disabling) problem with my K3. I called Elecraft and described the symptoms. The very helpful Elecraft tech told me a particular module needed replacment. A replacement was shipped that day and I had the new module in my hands (on the east coast) three days later, with return postage for my faulty module included in the package. Cost me hothing but a brief phone call. Deinstalling and reinstalling the module took 30 minutes max. K3 now fixed and fine. How many weeks would a Big Gun owner be without his pride and joy?? With Elecraft I don't feel the need for a standby radio, so I sold my Pro lll Icom. The Kenwood is next. Add to this the high level of expert help from Aptos, and the fact that I have never heard their telephone ring more than twice before a pleasant sounding (not a recording) lady picked up, and you have a win-win experience. 73 from George, N4YM K2 # 4758 K3 # 340 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Of possible interest Announcement - SteppIR FULL control with TRX-Manager
Hi - if this post is not acceptable - mods feel free to delete - my purpose is not to offend or 'sell' This is not directly related to the K3 - which I am very happy with - but TRX works with the K3 AND my SteppIR - so thought it might be of interest... also - my next project is to get Laurent F6DEX to FULLY - and I mean FULLY implement all the possible controls of the K3. so: Laurent, the author of 'TRX-Manager' just made the following post on the TRX-Manager Yahoo group: http://groups.yahoo.com/group/TRX-Manager/ TRX-Manager V 4.2.1 is ready. Main change is addition of a comprehensive SteppIR control Interface (STEPPIR protocol). Please see the help for setup (important information to be read). Special thanks to John VE3NFK for testing and Jim @ SteppIR for support. www.trx-manager.com This new addition to TRX gives you full control of the SteppIR - beam and vertical from your computer screen - including 'home' and 'calibrate' at a button press - something I have wished for a long time. It is not perfect - as the SteppIR RS-232 protocol is not a complete set because there is not enough memory left to get it all in - but it works very well. TRX is not free - but does have a 30 day trial.

RE: [Elecraft] RTTY Filter for K3
Ian, In the intense QRM conditions of RTTY contesting in Europe, I routinely use two cascaded 250Hz filters at 8215kHz and 455kHz in the 1000MP.

The nasty little secret is that all of the INRAD 250 Hz filters in the 8 - 9 MHz range have -6 dB bandwidths around 325-375 Hz.

A standard 170 Hz shift 45.45 baud RTTY signal needs at least 235 Hz (170 + 3*22.7) and the dual tone filter represents a 220 Hz (two 50 Hz filters with center frequencies separated by 170 Hz). After extended discussion with a well know RTTY op and K3 beta tester, I believe the combination of a 300 Hz 5-pole crystal filter, 300 Hz DSP and the dual tone filter will have a composite -6 dB bandwidth of about 250 Hz - about optimum for narrow RTTY.

When the channel is clear, copy of weak signals is not noticeably degraded compared with cascaded 500Hz filters; but when QRM appears, the narrower filters often make a decisive difference by preventing a strong unwanted tone from capturing the AGC. A 200Hz 5-pole filter for the K3 is arriving next week, and then I'll be able to do some A/B/C testing against the K3's own 400Hz filter and the 250+250 filters in the MP. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] RTTY Filter for K3
One thing I don't see mentioned much - something that makes ALL the difference in the world - is exactly *where* the bandwidth is measured on the response curve. Years ago I saw a lot of bandwidth measured at the -10 dB points (that was probably before many K3 owners were born - I haven't seen it for a long time but it was pretty common at one time). Then a *lot* of bandwidths were specified at the -3 dB or half power points. Now -6 dB seems popular. It seems like Inrad may be using -3 dB for some of their measurements. The corner of the bandpass is covered by the data, but it looks very much like that 455 kHz 300 Hz filter is 300 Hz wide at the -3 dB points.

Re: [Elecraft] K3 Shields - Theory of Operation?
On Fri, 2008-05-16 at 12:50, Dan Levin wrote: Naïve question... I'm looking at the shields on the inside of my K3 (the one that separates the RF compartment from the front panel, and the one that segregates the KPA3 from the rest of the system), and I'm wondering why they work :-) My questions fall into three areas: 1) These shields are full of holes and slots. As long as the longest dimension of the hole is much smaller than a wavelength (less than 1/10 wavelength is the rule of thumb) it doesn't degrade the shielding very much. 2) The PC board forms the bottom of the shield box in both cases. Yet the shields aren't connected electrically to the boards. It looks to me like the PA shield is indeed connected to the RF board (motherboard) and also to the top cover. (Notice how the paint has been removed on the top cover to make a good connection.) It looks like the front-panel shield is connected to the front-panel board through the chassis. 3) The connectors that pass through the shields, especially the ones that pass through the front panel shield, don't appear to be RF proofed in any way. That can indeed be a path for RFI to couple through the shield. I think the general answer to your question is that the best shielding is a solid aluminum box with all power and signal lines going through coaxial feedthrough capacitors and all coax cables using connectors mounted to the box. Sometimes you have to do that kind of thing if you are designing something like a microwave spectrum analyzer (I used to work for HP/Agilent) where (1) the wavelengths are very short, and (2) all detectable spurs must be surpressed over a very wide bandwidth. But for an amateur transceiver operating in the HF range, the requirements are far less stringent.

Regardless of whether I'm set MAIN:FP or MAIN:rP. Any ideas where to start first? ttfn -- 73, Dick ka1oz Middleborough, MA K3/100(Kit) SN 000859 Titan-DX (to come) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 has no TX audio...any ideas?
Couple of questions; What is your monitor setting? What firmware release? Does the speaker work? Sidetone in CW? Did you config the speaker on?

RE: [Elecraft] RTTY Filter for K3
I agree with Joe's summary. Note that the 250 Hz 8-pole filter is really about 370 Hz at the -6 dB point. Any of the current 500, 400 or 250 Hz crystal filters will be fine for RTTY. With any of them, the DSP can be narrowed to 300 Hz without rolling off the outside edges of the two tones. Note that the Dual-Tone Filter for RTTY is cascaded with the crystal and normal DSP filters and if either of the latter two filters are 250 Hz (at -6 dB) the three-filter-cascade will have significant roll-off on the outside skirts. This has the undesired effect of moving the two filter peaks much closer together than the 170 Hz split. That said, I have been running the 370 Hz crystal filter (aka 250 Hz 8-pole) with 200 Hz DSP and the DTF for several months now in RTTY contests. While the resultant passband was indeed rolled off as described, this was overall a net benefit in heavy pileup conditions because it filtered out the pileup better, producing a clear callsign quicker, despite the rolled-off passband. In other than heavy pileup conditions, it is best to keep the DSP at 300 Hz or higher, especially for copy of weaker signals. In the future, there will probably be a 200-400 (or 200-500) Hz variable 5-pole crystal filter that will be ideal to track with the DSP for high performance RTTY reception, ranging from weak signal to heavy pileup conditions. 73, Ed - W0YK -Original Message- From: [EMAIL PROTECTED] [mailto:elecraft- [EMAIL PROTECTED] On Behalf Of Joe Subich, W4TV Sent: Friday, May 16, 2008 12:28 AM To: 'n4lq'; elecraft@mailman.qth.net Subject: RE: [Elecraft] RTTY Filter for K3 I am watching RTTY right now and using the 200 Hz 5 pole filter. The 170 HZ shift fits perfectly within the passband. After making extensive tests and plotting the selectivity curves of the 200 Hz filter in my K3, I'm convinced that it is too narrow for reliable weak signal RTTY operation, particularly in conjunction with the dual-tone filter. The measured -6dB bandwidth of the 200 Hz crystal filter was 209 Hz and the composite bandwidth of the 200 Hz crystal filter, 200 Hz DSP and dual tone fitter was less than 170 Hz. A standard 170 Hz shift 45.45 baud RTTY signal needs at least 235 Hz (170 + 3*22.7) and the dual tone filter represents a 220 Hz (two 50 Hz filters with center frequencies separated by 170 Hz). After extended discussion with a well know RTTY op and K3 beta tester, I believe the combination of a 300 Hz 5-pole crystal filter, 300 Hz DSP and the dual tone filter will have a composite -6 dB bandwidth of about 250 Hz - about optimum for narrow RTTY. The currently available, 250, 400 or 500 Hz filters in combination with a 300 Hz DPS bandwidth and dual tone filter are very close to optimum. 73, ...

[Elecraft] K3 Duty cycle
I haven't seen anything on the K3 duty cycle. What is considered the practical duty cycle of the K3/100 in RTTY mode for example? I.E. will it get hot running 50% transmit / 50% receive in a full power 100 percent mode? 73, Jim KG0KP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
