[Elecraft] 3B7 with K2/qrp
Okay...had to give it a try. Just worked him on 40m after about 3 minutes of calling. 2.5 minutes spent calling blind. Then I heard him call a G3, found the G3 on VFO B (no dual rx) and I was the next call. K2/qrp (no KPA here!) Now for 160?

[Elecraft] K3: CW decoder
I, for one, am looking foward to seeing lots of folks who do not normally do CW start to show up during the CW contests. 99% of the code sent during the contest is nearly perfect. so I am hoping that the decoding will be pretty good...good enough to encourage those normally too timid to try CW to get on and make some Q's. While some ops MAY be too embarrassed to use a code reader (external box), with the K3, it is a hidden tool...no embarrassment factor if a friend stops by. And really, since CW is not longer a requirement, there is nothing different than LOOKING at the decoding of RTTY or PSK or whatever...just another digital mode for those who don't know the code. I've seen code readers at work and they a distraction for me. I copy the stuff faster in my head than the software can decode and display it. Analogy: One time, my family was watching the Yankees game on TV. We didn't like the TV announcers as much as the usual Yankees announcers via radio, so turned on the AM radio to listen and watch TV with the AF turned off. We couldn't do it. The TV had a much longer delay (FCC mandated?) than the radio. We HEARD what was happening well before we SAW it. Same with decoders (for me). But for those who would feel more relaxed with a decoder...GO FOR IT. And please be sure to work me in the contest! Who knows...if Elecraft can do it in reverse (copy SSB and have it come out as code...or use the paddle and have the rig xmit SSB), we might even see the likes of Ron Wright on sideband! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 on the bench at ARRL
Fellow K3 droolers If Elecraft wishes to have the BEST opportunity for the ARRL to laud the K3 (assuming that it will indeed cause jaws to drop), they better get it in soon. Historically, the BEST reviews (IMHO) are those that are conducted by one of the FAMOUS contesters DURING THE BIG ONE (CQWW ssb and cw). Passing the rig around to the likes of Mark Wilson, Tom Frenaye, or Dave Sumner DURING THE CONTEST will, if successful, have the seal of approval from those in the game and in know who are RECOGNIZED as peers (or better) by contesters and DXers. The BEST reviews historically run the radio through its paces on BOTH MODES. OTOH, if the radio isn't ready for prime time, don't send it in. If I were Elecraft, I sure wouldn't want to read When the power exceeds 100 watts, the SWR goes nuts in QST as part my NEW radio review. However, I really thought that the ARRL tested radios which they PURCHASED so as to ensure a random, production radio. I don't think Elecraft can send them one as the test unit. Maybe there is some wiggle room? Maybe I'm wrong? As a consumer, I would rather the testing agency bought a random production radio as opposed to having one potentially cherry-picked by the manufacturer and sent in for testing. As for Sherwood and RadCom/Peter Hart, maybe they'll take whatever they get. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] u-Tune for K3
I know the list owner has chided against me too comments, but ZV has it summed up nicely and I fully agree with his comments and findings. $500 for just 2db? Analogy: If you drive a car w/o air conditioning, and the mfgr let you add a turbo speed fan for extra cooling, does not mean that you NEED (as opposed to want) a turbo fan option in a car that HAS air conditioning. The final level of enhanced cooling from the turbo fan non-AC car still won't come close to the car with real A.C. and no turbo fan. Back to radio: With the K3, you just don't need u-tune units cuz the K3 is already heads and shoulders better than the 2000D even with all that other u-tune stuff. Beside, for $500, you can get another REAL receiver (KRX3) instead of u-tune to help a less-than-spectacular rx (2000D). de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] totally honest, brutal request for K3 deliveries
Bob (et al): I have nothing to do with Elecraft inside operations in any way, shape, or form, but your request has only ONE answer. If they still waiting on parts, in terms of p.99, Elecraft has ZERO idea of when the radios can or will ship. The ONLY time they can forecast delivery dates for the K3, with any real probably of success, is AFTER they receive all of the correct and properly functioning parts. Once those are in-house, then Elecraft is in control. Until then, Elecraft is NOT in control. Vendor promises, while often trusted, are nothing but words. Parts in hand is the only thing that counts.This is not a criticism, it is simply reality (what you called brutally honest). If you are looking for honest communications (and I think we all are), then I'd ask Elecraft to let us know when they have all of the parts in hand AND have confirmed that they are the right parts AND that they actually function as per/meet Elecraft specs. Failing receipt of everything from all of the vendors, anything posted about delivery is, in reality, total guess-work. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: type of Keying
Well, this topic has migrated from requests for my kind of keyer to a comparision of the various types (including words such as relic). For the life of me, I can't see the practical difference. I understand the difference, but comparing iambic to utlimatic, I see essentially the same number of finger movements for the majority of letters/numbers. 1. The letter C in iambic requires each finger to close and open once. Ultimatic seems to involve more movements. 2. The figure 2: same for both: each finger closes and opens once. 3. The letter J: a shorter version of the figure 2. Both methods = same number of finger movements. 4. Punctuation period: Iambic seems to have fewer movements. 5. Letter R: both the same: each finger closes and opens once. 6. Punctuation ?: Thumb closes and opens twice with iambic. Ultimatic: thumb opens/closes just once. I'm not going to go through the entire alphabet, it it seems that this is purely personal preference with no advantage for Ultimatic over Iambic. Am I missing something? Please enlighten me...I am always anxious to learn! :-) de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

You guys crack me up. On the one hand, some of us are trying to get as narrow as possible (200hz) and on the other hand, some of us are looking for high-fidelity, surround sound, theatre quality. Gee whiz...this is ham radio (communications). This is not your home theatre (dolby 5.1 etc). Speakers? What's a speaker? I haven't used a speaker since 1967 when I learned how to plug in a set of headphones. You'll have plenty of drive (enough to blow your ears off, I'm sure) and you can get a hi fi set of 'phones for not much $ (or spend as much as you like). Good luck getting a rig to match the quality and range of the 'phones. I use communciations headphones...great on CW, rather restricted on SSB (but then again, I have mostly forgetten the phone.). If I want to hear 20 to 20k, I'm not going to use ham radio as the driver. Each to his own (a liberal paraphrasing of Don's comment). I do hope and pray that the audio output is not tarnished with hisss and noise (ala the Drake TR7 - great front end for its day, worst audio amp ever made).

[Elecraft] RE: K2 drops receive level
Tim: I'm no K2 guru, but what you describe is classic of a poor/intermittent connection somewhere on the way to the antenna. I've experienced this with many radios, going back many decades. The dit (transmitting) somehow reestablishes a better connection at the point of failure. This might be at any coax connector (from the back of the radio all the up to the antenna). Try tracing your coax and connections along the way. Open up all contact points and clean them up (emery cloth, board, your favorite contact cleaner, etc). At the antenna (and elsewhere too), be sure your connections are not only clean, but tight. I'll leave the suggestions for what to trace for inside the K2 up to the K2-masters. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] RE: OT Dell Production Delays
Simon: WARNING: MISCELLANEOUS RAMBLINGS FOLLOW Anyone who places an order for and PAYS for a not-yet-released product should understand that s/he is entering the DANGER ZONE. Anything is possible, especially DELAYS and CHANGES in specs. To place a prepayment or deposit on a new product and expect everything to go smoothly is simply being naïve. Folks always have the other options to 1. wait until the product is released 2. wait until it has has received favorable reviews by those who already have it 3. wait X months after release until it is proven. We each take our own risks. We each determine what level of risk any decision we make carries (whether we realize it or not). And BLOGS (including this one) tend to bring out both the best and worst in people. Once the ball (opinions) get rolling in one direction (currently bad for Dell), there is always the snowball (me too) effect. People LOVE to complain...ESPECIALLY in public. Luckily (at least in this country), one can always cancel if the product is not delivered within 30 days without penalty. In theory, the K3 might not be ready for Prime Time for another 6 months (yes, I did say IN THEORY). What would be the Elasticity of Patience (borrowing from economics) for the K3 before folks get upset? For me, since there is NOTHING else out there that I would rather have to replace my current radio (that I can afford), I'm willing to take my chances (of which there are potentially many).

[Elecraft] K3: 21st century assembly manual
Hi all: Well, I would like to see streaming video for the assembly instructions. As (if) things change, simply add a modify the link for that portion of the instructions. And no real language issues! Photos are nice, but hey, kinda fossil-technology. de Doug KR2Q http://photo.net/history/timeline and from http://www.rleggat.com/photohistory/ The first successful picture was produced in June/July 1827 by Niépce, using material that hardened on exposure to light. This picture required an exposure of eight hours. On 4 January 1829 Niépce agreed to go into partnership with Louis Daguerre . Niépce died only four years later, but Daguerre continued to experiment. Soon he had discovered a way of developing photographic plates, a process which greatly reduced the exposure time from eight hours down to half an hour. He also discovered that an image could be made permanent by immersing it in salt. Following a report on this invention by Paul Delaroche , a leading scholar of the day, the French government bought the rights to it in July 1839. Details of the process were made public on 19 August 1839, and Daguerre named it the Daguerreotype. The announcement that the Daguerreotype requires no knowledge of drawing and that anyone may succeed and perform as well as the author of the invention was greeted with enormous interest, and Daguerreomania became a craze overnight. An interesting account of these days is given by a writer called Gaudin , who was present the day that the announcement was made. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] that Drake or Collins sound
WØYK sed: [snip] The K3 simply sounds better on all modes, including RTTY. The band noise is less severe to listen to, and the difference is striking just having the ProIII in one ear and the K3 in the other with no signals in the passbands. Yet, the K3 dynamic range accepts a much larger range of signal levels and the K3 pre-amp can be left on even on the low bands where the attenuator does NOT need to be turned on except in severe situations. I ran with the pre-amp on, maximum sensitivity, and the attenuator off on all bands 10-80 for the entire NAQP. The K3 was less fatiguing to listen to for long periods of time with the audio sounding very natural, whereas the ProIII does sound digitized or artificial. (Maybe if you're not old enough to have spent many hours in front of a Drake or Collins receiver, you can't appreciate this point!) [end snip] This is GREAT news for me! While I don't do RTTY, I sure do CW. Over the years, I have listened multiple times on the 756 Pro series, and I must say that to my admittedly sensitive ear, I just can't stand that digital sound (very flutey, if there is such a word). From home, I can even hear it on the xmited signal. I can pick out an Icom radio a mile away. Not bad...just not like it should be. Normally, I HATE subjective opinions...but this one that really rings true.

[Elecraft] OT - my history of zero beating
I really have to chuckle a bit about matching tones or zero-beating. When I was first licensed with a novice class ticket (rock-bound), one learned to tune the band looking for answers. It was common-place to answer a CQ by calling the CQer 5, 10, or even 50 kc away5 or 10 kc away often got results. 50kc was less common, but not rare. I also remember going over to a ham's in the same town (who had phone rigs) and watching him call CQ on 2m and tuning the band ...MEGACYCLES worth, looking for an answer (which he got). When I answer a CQ these days, I wait a bit first (1/2 second) to see if there are any other callers. If there are, I slightly change my QRG so I'm not calling on top of him. Zero-beat...what's that? :-) I don't know what the fascination is with zero beating the guy you're calling. Of course, with the advent of the K3 super filters, this might become necessary if op's crank 'em all the way down for routine CQs. LOL And yes...it is getting bad waiting for the K3's and sorry for the summertime bandwidth. de Doug KR2Q PS...after the last Simon photo, I guess we might next hear about no need to zero beat cuz you couldn't. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: CQ FT243 crystals
Dear Elecrafters: As we all marvel at what Elecraft can do in a tiny box, some of us are also stuck in the past. My first commercial radio was a Heathkit DX20. After I upgraded around Dec 1966, I sold it in early 1967 so I could buy a radio with SSB. About 15 years ago, I ran across a DX at a local hamfest and bought it. Since then, I've been collecting (slowly) FT243 crystals, as I find them available locally. It's time to expand my search. Do you have any FT243 (sometimes labeled as Z2) crystals collecting dust that you'd like to offer up for my collection? My mailing address is current at all URL lookups.

[Elecraft] 13 wpm (was 20 wpm)
Yes, I remember Mr. Cigar out of NYC very well. In late 1966 (or Jan 1967?) I approached the NYC Federal Bldg with my mom (I was 14). There was a female guard/receptionist just inside the entrance. She looked at me, my mom, and said, Here for your FCC test? and told us the floor - which I forget now. It was a long elevator ride up and the sissors-gated pathway finally opened up. The place was old and filthy with long hallways (at least that's how I remember it). Walking in, there he was (others had warned me). There was a row of desks along the wall opposite from the windows (which had 100 years of filth on them). I was seated at the first desk with a straight key. I copied what was sent and after some waiting, got the nod. Then it was my turn to send. I touched the heavily patina-ed key, but it didn't send anything. I mentioned this and was moved down a few desks. I touched that key and whomever was there before me, had it set to one molecule spacing. Just breathing on it caused it to key. I mentioned this (again) but now was told, This is the standard key. Either send on it or you fail. I grabbed the knurled, brass set screws and, with all of my might, tried to loosen it up. Nothing. I tried again. Nothing. Mr. F was getting annoyed. I gave it one last try. POP! the thing loosed up a mile wide. He said, SEND. So I starting sending the text. The gap must have been 1/4 inch..I was REALLY pounding the brass and it sound like I was hammering a nail. I clearly recall EVERYBODY in the room stopping what they were doing and looking at me. Gawd! But I kept sending. Mr. F was not happy with my L's and told me so. It was the spacing, I said. He said, Let me hear 5 L's. UGH! I managed to get them out and he said OK. I'm sure I was sweating to death. Looking around, everybody was still starring at me but they soon went back to their exams when they saw that I was finally done bothering them. A day I shall never forget. Of course, after passing (on my first try), my mom swung by Harrison Radio.

[Elecraft] RE: Programmable mode/band Fwd: K3 suggestion for future release (read later)
Dave: Glad I'm not the only one who is thinking this way de Doug KR2Q -- Forwarded message -- From: DOUGLAS ZWIEBEL [EMAIL PROTECTED] Date: Jun 17, 2007 7:10 AM Subject: K3 suggestion for future release (read later) To: Eric Swartz WA6HHQ - Elecraft [EMAIL PROTECTED], wayne burdick [EMAIL PROTECTED], lyle johnson [EMAIL PROTECTED] K3FAQ sez: How do you change bands on the K3? Do you have to toggle through all the bands to get to the desired one? You can change bands in several ways: - With the BAND UP and BAND DOWN buttons - Using direct frequency entry; two methods: 1. Enter a frequency in MHz and then a decimal point, e.g. 7. jumps to 7.000 MHz (40 meters) 2. Enter a frequency in kHz and then a decimal point, e.g. 1825. jumps to 1.825 MHz (160 meters) - Using general-purpose memories (100) for your favorite bands/modes, including 5-character names that you assign to each memory) - Using a computer program to control the radio HOW ABOUT ADDING THIS: When using the band up/down button, enable a feature that allows to SKIP certain bands. I am thinking contesting. For example, to get from 10 to 20, using the Band Up/Down would take 4 pushes. If you know that you won't be on 12 and 17 (cuz it's a contest) and you could disable them (or skip them, whatever you want to call it), then it would only take 2 pushes of the Band Up/Down button. Additionally, and even though it might be faster to go from 160 to 10 by pushing the UP button, during a contest, my brain doesn't usually think that way and I go back DOWN through 80, 40, 30, 20, 17, 15, 12, finally to ten. It requires less thinking (believe it or not), even though it clearly would take way more time. While the 160 to 10 example is easy to figure out, but if I'm on 40 and want to get 10, I don't want to think about or remember what is the fastest path. So just thinking higher band vs lower band is simpler (at least for me). As I really don't know how the memory function will work yet, this might be moot. From your description, it sounds like pushing 7 decimal gets you to 7.000 instead of the last QRG you used. I assume that using the Band Up/Down will get you back to your last QRG. Yes? Also, I am pretty sure that you actually would be required to do at least one more keystroke (FREQ ENT) to get into direct freq entry mode, beyond simply tapping 7 then decimal point. I assume that you have to terminate the sequence with another FREQ ENT, otherwise how one enter a discrete frequency (say, 21066)? So if I counted correctly (to just change bands using the keypad), you need at least 4 key strokes. Might as well use the Band Up/Down. As I sed...for a future release, if you think there might be wider appeal than just for me. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

So Ken hates the word Ham when used to describe us, well, hams. ME TOO! 1. As a adjective to RADIO, it adds no meaning except to other hams 2. To the uninitiated, is sounds rather silly (at best) 3. It does not convey the technical nor operating skill levels required/achieved 4. Zero offense to Elecraft, but I can only imagine what hands-on ham radio conveys to a non-ham. LOL For me, I'd rather be called a short wave radio operator, even though I operate on frequencies outside the short waves. At least short wave is a term many folks (but probably not kids) understand. Then again, I'm sure kids today would get a good laugh (and not much more) from the phrase ham radio.

Dear Field Testers, Lyle referred me to YOU! I recently inquired about how the SWR is displayed. The answer is now part of the FAQ. This is a really exciting method (nice trick), but I have a question, perhaps a concern. If I'm on CW and doing 40 wpm QSK (common for me), is the DISPLAY (S meter // RF/SWR) going to flicker at 40 wpm as I go from TX to RX? Can the display keep up?

[Elecraft] OT: moving xtals
Al said: Then we'd disassemble the xtals and soak em in acid for a few minutes to tweak them up 3 or 5 KC. I never did that. I used to make a slurry with Comet (the cleanser, before it went grit free) and, using an index finger on the xtal, make circles in the slurry to grind the xtal (move it up in frequency). Using this method, you could move a xtal all the way up the band, but it took time. And you would measure the frequency by transmitting with it by FINDING it on your receiver, then taping a paper label to the xtal with the new QRG. To lower the frequency, I used to make figure 8's using solder to draw on the xtal's flat surface. Of course, you could not lower the frequency too much that way or the xtal would stop vibrating. Ah...the fun days when nobody thought about holding solder in their hands (or mouth) and intentionally inhaling solder fumes (tendrils) cuz it smelled so good. de Doug KR2Q PS...I have a crystal for 7000.1 - by is that a good one...would multiply up on LOTS of bands! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: large scale production of quartz crystals during WWII
Of course, one of the pioneers was Hazard Reeves (K2GL, SK in 1986). Buz was a world class engineer and beyond that, is still well known for the winning-est Multi-Multi Contest Station in history (I operated there from 1976 to 1986). In fact, the Multi-Multi Category was invented because of Buz' operations in the CQWW DX Contest. He won everything, so they created a new category to distinguish what he was doing from what others were doing. Can you imagine competing head to head as a Single-Op with M/M because there was only one category?

[Elecraft] S meters and audio quality
Here is (was) my take on S meters: http://www.ac6rm.net/mailarchive/html/elecraft-list/2007-05/msg01072.html Next. I think that an adjustable sensitivity for the S meter (how many db/S) is great for my purposes. Frankly, I don't care if the guy I'm working is S1 or 20 over, just so long as I can hear him. However, when I am doing things that require a RELATIVE scale (testing antennas, aligning things, etc), all I care about is is condition 2 better or worse than condition 1? One of the YUCK things about a bar graph S meter is that you can't see tiny increments (at least I can't). If I can twiddle the db/S unit, then I suspect that I'll be able to observe TINY changes, more like what I might be able to see on an analog meter (mechanical). So I think this sounds GREAT to me. Hope it goes does down to 1db per S unit! I do have an 82db step attenuator, so I'm all set. Audio: I think a classic case is the TR7. For the time, a great front end right out of the box. But OMG, what an aweful audio amp!! It was wonderful to hear tiny signals when surrounded by other BIG signals (especially at M/M...we had 10 TR7's), but wow, did one get a headache from all that GARBAGE audio (I can't even call it bad quality because it still has the word quality). How many big dollars when into good design (for the time) only to send it out through a 99 cent AF amp. UGH...

[Elecraft] contest reflections on K2 - addendum
Hi all: I was going to post this privately, but since I've received several private (direct) comments in addition to the public postings, most recently by Dave, G3YMC, I'm making it public, using up some bandwidth, as I think this might benefit others. 1. QSK. This is user skill level dependent. If you do 20 wpm or less, the K2 QSK may be fine for you. During contesting, I am going at least 32-34 wpm, and not uncommonly at 40wpm. At these speeds and during a contest, I NEED to hear everything immediately (that is what top-end contesting is about). So not hearing between dits at slow contest speeds of 32 wpm is an issue for me. NOTE that I still used the K2 despite that deficit because OVERALL, it is a great radio. But for someone used to real QSK, this is not real QSK. Ask other serious contesters and they will say the same. For most K2 users, who are clearly not serious contesters, this is not an issue at all. Since the K3 says very much better QSK than the K2, I would easily assume that the deficit is real and acknowledged. 2. Stable power output. I use multiple antennas PER BAND. All are resonant (monoband yagi's, Optibeam tribanders, and quads). EXAMPLE: During the WPX contest that took place this weekend I may have been working Europe on my yagi pointed to EU (about 45 degree from NJ). If I hear a potential qso in South America (170 degrees), I simply turn the antenna switch to my QUAD which is already pointed south. When I do that, the power output indicated on the K2 DRAMATICALLY changes. It might go from 5 watts to 2 watts or to 15 watts! I am not sure why, but some of the technical guys explained it to me long ago (something about how the power output is set [calculated] on the K2). I cannot justify entering the qrp category of a contest if the radio is running 15 out when qrp is defined as 5 out. So whenever I change antennas (which I do a million times during a contest), I have to hit TUNE to make sure the power stays at qrp (goldie locks syndrome). NOTE: I do not have the internal antenna tuner. I don't know that would make a difference or not. IF THIS IS NOT HOW THE RADIO SHOULD WORK, PLEASE TELL ME! W3FPR tells me that this IS how it works. 3. AGC. Using the K2 S meter, signals here range from zero S units on the meter (even though atmospheric noise is supposed to be S1) to 40 or even 60 over 9 (all LEDs lit up). A 40 over 9 signal is VERY LOUD in the phones while S1 is not. This has to be real because the K3 provides tools to address this. I assume (know) that this is how the radio was designed. Many contesters have commented (here) that they like this aspect because it is easier to pick out the LOUD signals in a big pileup. Different strokes AND FINALLY I have been reminded that the K2 was not designed as contest radio...that it simply ended up being so good in other aspects, that it ended up being that way. Agreed. My comments were posted in response to a recent number of reflector posts suggesting improvements for the K2. I doubt that any of these will be addressed because the K2 is a fine radio the way it is and being a serious contester puts me out of the main target market for the K2, esp now with the K3 on the near horizon (which I have ordered). But if Lyle, Eric, Wayne, et all ever catch their breath, and if K2 users want improvements, I thought I'd add my contester-centric dime. SO IN CONCLUSION The K2 is an awesome value and for all, including serious contesters. At US$600 base, nobody expects it to be 100% perfect for all market niches. This is clearly the ABSOLUTE BEST VALUE going in ham radio. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] a K3 owner's contest reflections on the K2
HI all: Just finished the CQWW WPX cw contest. Weird condx, but lots of fun. I note lots of comments on the K2 of late (this weekend).here are my 2 cents (maybe a dime). After having been plugged in for most of the weekend, here are my take-aways (none of which are new). 1. I own the base K2 with the 160m module. So base price was under $650. 2. You simply cannot buy any radio that performs this well under harsh conditions for anywhere near this price...even used. The performance on the lows band is unsurpassed for anything even double or triple the price (probably a lot more). 3. What's wrong with the K2 for cw contesting (IMHO) A. The QSK is almost worthless. At the first setting above Ø.ØØ, you just can't hear between the dits and dahs. And at zero, it's too noisy. B. Every time I change antennas (even on the same band), I have to depress the TUNE button so that I can get stable qrp output (5 watts). This is an extra step I did hundreds of time this weekend. It is now 2nd nature, but a royal pain (yes, all my antenna are resonant, but just not the same according to the K2. C. The AGC is not set up correctly. Weak signals are, well, too weak (audio) and strong signals blow my ears off. The AF knob is my friend...but I don't want it to be. I don't use RIT/XIT in the contest (since Im qrp, I don't run much), so I don't miss the lack of the CLEAR button. I use the 400hz filter (forget what it is exactly) and it is wide enough so I can hear callers substantially off frequency without RIT'ing. For my style of contesting, I NEVER change the XFIL selection (good ears, I guess). Anyhow, all of the above are SUPPOSED TO BE addressed in the K3. Hpe to find out soon. Anyhow, the K2 is a might fine contest radio for qrpers (it is not IC7800 for those who like dual receive, a band scope, etc etc etc). I cannot think of a better radio VALUE for contesting. This is hands-down the clear winner, probably over the K3 also. The K3 is (hopefully) also a great VALUE for contesters, but the K2 is just impossible to touch. OH yeahI worked 896 stations, 439 prefixes, and a claimed score of 991,262. Not too shabby for a $600 box. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

I never took the time to notice if they were soft rubber buttons. They felt fine to me and I did not come away with the feeling that they were soft or rubber. I mean, they don't have a click like the old IBM XT keyboards, but I never had a sense that I didn't know when the the button was pushed (and I did push them at least a few times, esp the RIT/XIT and CLEAR buttons). :-) Maybe someone else actually focused on the buttons. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: course wanted: Panadaptor 101
Hi all: Just as lots of folks needed a tutorial on what a roofing is (and isn't), I'm sure there are at least an equal number (now including me) that need an introductory course on Pan displays (specifically, what we forecast Elecraft might do versus what Softrock can already do - and not do). It is hard for me to (currently) understand how there is something out there already for US$11.00 that apparently provides what is wanted. Or maybe it doesn't? I gather that we need a PC to run Softrock and if you're like me (with kids), you have lots of computers around the house that are old or minimally used, or currently in use in the shack but with lots of untapped horsepower still available. Or maybe you just need an excuse to upgrade. I have noted the article in a recent QST on soundcards and I wonder if we need the best sound card to simply get a Pan display (not running an SDR radio). What sort of additional functionality might Elecraft include on theirs that would not be available in the Softrock (looking for conjecture)? And if you can bascially do this for $11.00 (assuming we already have a PC we can use/share for this app), why would Elecraft even bother to start to design their own Pan display? And my final request for the gurus here...please keep it simple and take an operational approach. I don't care how it does it, I want to know how the user can USE it, and to compare/contrast Softrock and whatever E might come out with.

[Elecraft] Dayton review
Hi all: Arrive in Dayton Thurday, left Sunday. Good time. Comments: K3: I bought one (paid in full). K3/100. I can add more later and by the time I get mine (Sept build, maybe early Oct delivery?) the other stuff should be sitting on the inventory shelf so no need to make those decisions at Dayton. Interesting method of demonstrating the QSK (turn off side town and listen to the band hiss on receive, nothing recovery time. Not a great demo, but better than nothing. I'll see for sure when it arrives. Reading about the features is one thing, seeing them all work together (seeing because not much an antenna was available) was much more impressive. Got to see how things interact with other and how flexible/easy they are to manipulate. Impressed. IC7700: Rather boring. IC7800 without dual receive or dual watch (which even the 756 does). Price point said to be between $5 and $7k. Heard others say $6k (which is between 5 and 7 - LOL). Pretty to look at, bummed about performance. Just think, you could buy 2 - 3 K3's (depending on how you configure them) for the same cost. I don't think the pan display is worth that kind of $ differential. But then again, I am motivated by performance and not looks. With two K3's and something else (aftermarket) for the pan display, you would still save a fortune compared to single 7800, have more flexibility, better specs (likely), and still have $5K left over. No brainer unless you like to brag about how much money you threw away. Prior 7800 owners excepted as it WAS the best thing going (before). FT9000: This was really funny in the extreme. It is so overboard. If any of you (OTers) ever read MAD magazine, it is like the cartoons they used to run. For example, the one where they showed a new car from the 60's..it has 20 rocket fins on the trunk and 15 headlights. I'm sure it is a nice radio, but gee whiz. Make sure you budget to rent a crane to move it. Flex 5000: GREAT specs, zero radio-ness. One method of tuning the band is to use a hand tool (like you use on a pdf file) and you pull the band across your display (like Goole Maps). Very, u, different. User interface (tactile) is all but lacking. There is this external device with pushbuttons and a knob to use, but I like at least two knobs (one for each VFO or one for VFO and one for RIT/XIT). If they ever get a better (much better) human interface, this will be one to watch. The K3 fits nicely between the FT9000 (overkill on a grand scale) and the Flex 5000 (a mouse). Can't beat a radio that you can lift up off of the desk with one hand so the other hand is free to move other stuff around. Tokyo Hi-Power: 1.5KW output solid state amp. Very nice. Waiting for type acceptance. Price proposed as $6K. This is the ONLY brochure I actually took home. Not in my future, but nice to look at. Still can't wait for the official specs to be published (within next six weeks?). de Doug KR2Q PS Great to meet Eric, Lyle, Wayne from Elecraft and esp enjoyed chatting with Don, W3FPR. He is as nice in person as you would expect from this 10,000 helpful posts. PPS...best other Tee Shirt: Power is no substitute for Skill.

Not a great demo, but better than nothing. I'll see for sure when it arrives. Should be: Interesting method of demonstrating the QSK (turn off the side-tone and listen to the band hiss on receive, noting the recovery time. Not a great demo, but better than nothing. I'll see for sure how it works when it arrives. Sorry about that. Also: Speaking of the K3 with the whip at Dayton. While there, Wayne was able to tune in one station on CW (using a tiny whip INSIDE the arena!). He cranked the BW down to 50hz and it sound GREAT. No ringing, EASY tuning back and forth across the signal (did not just appear out of nowhere, which I like) so you could set the pitch the way you liked. I was very impressed with what 50hz sounded like (and even more about what it didn't sound like). de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] S meters in the USA
Arghwhat a nit-picker's delight. The reason why you get You're S9 but please repeat everything is that you can be S9 and be covered by QRM/QRN. Check out what the ARRL says about RST (page 2 of the document). NOTHING about volts. It's all subjective. http://www.arrl.org/FandES/field/forms/fsd220.pdf For me the purpose of an S meter is as a RELATIVE comparison tool. This is ham radio, not a laboratory test bench. Who care what the S meter says? If you can carry on the QSO or exchange, S1 is as good as 30 over. If someone wants to check ant A vs ant B or station A vs station B, then all they really want to know is which/who is louder. If they want real measurements, then the person on the receiving end should use a calibrated step attenuator and use it to match signal levels. But no ham is likely to ask someone else for an accurate measure in uv or dbm unless they already know that the other guy has a REAL means of measuring AND has real reason to want to know. For most of us hams (99.9%), stronger and weaker is good enough for comparisons that we might want to do. Sun is up...off to Dayton.

[Elecraft] off to Dayton! 1 more time (sigh) on Roofing filters
Readers would do well to actually read the posts or do a SEARCH on the archive. Will you have an issue with only the stock roofing filter? Eric already gave us the answer with parameters. If you only use the 2.7 kHz stock filter for CW or data operation you will be significantly desensed once signals within that filter's bandwidth exceed about S9+25. That means that you have to park within 2.7 kc of another guy (cw or data) who is S9+25 on the K3 (calibrated) S meter. How many of you would sit there and fight it out? If you're not one of them, then 2.7 is FB for you. http://www.ac6rm.net/mailarchive/html/elecraft-list/2007-05/msg00590.html de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] start without ANY extra roofing filters....
W3FPR said: The real facts are: 1) I will order my initial K3 with only the stock 2.7 kHz filter. followed later by My best recommendation at this time: Understand the consequences of depending on a wide roofing filter while making your decisions - if you choose only the wide filter, live with it for a while. First, for the majority of readers here, I fully agree with the approach of starting out without anything extra (roofing filters). Second, I really have to chuckle at the entire RELATIVELY of these discussions (not directed to Don, whom I hold in high esteem). Other than Orion, or home brew/post-market mod, you simply can't get a NARROWER roofing filter in any double/triple/quad conversion ham radio on the market than 3.0kc. A 2.7 kc roofing filter is not wide compared to what else is out there...quite the opposite, it is THE MOST NARROW (exceptions cited above). You are STARTING OUT NARROWER than everything else! Calling a 2.7kc roofing filter wide is a big misnomer (at least for me). As an example, the highly respected (by many, not me) Icom 756 Pro III has a 15.0kc wide roofing filter. Now THAT IS what I call wide. http://www.icomamerica.com/products/amateur/756proIII/ Excluding Europe and Japan, the odds of a non-contester, non-top band-DXer needing anything narrower than the stock 2.7 for ssb/cw is remote, at best. I dare say that even most contesters won't need anything narrower...only the upper tier who want to battle it out with the best. The number of times a contester will actually NEED a 500 hz roofing filter is very small (comparing the number of QSO's where it is needed to the total number of QSO they make during a contest in which they are top-tier). Of course, there is no accounting for those who simply want it even if they never need it. Price elasticity (for you economics buffs) for a item perceived to carry PRESTIGE can have no known bounds. :-) de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Wayne's comment on Filter Selection
Wayne: Thanks for your multiple posts. Your responsiveness is beyond impressive. I would not doubt the CTO's point of view on his own design. But now, I do have other comments and I would greatly appreciate learning how you see these from your point of view. Let's talk CW. If a triple conversion radio has a 15kc wide roofing filter (1st IF), there is a genuine need for a narrower filter in later stages (let's say 2nd IF). Since we are letting in a 15kc swath of the band (ignoring IMD and AGC pumping for the moment), we might find that the signal we want to copy is very close (say 500hz) to an interfering SINGLE signal. We can use a narrower (multiple choice of selected or variable passband type) filter to isolate the desired signal from the interfering signal. These filters work well at this. It is my presumption that the K3 DSP at 15kc (some call audio), is the equivalent of the 2nd IF narrow passband filter you referenced in other radios. All the time, other radios still have a 15kc wide (not to be confused with the DSP operating freq) roofing filter, still letting other signals into the front end. If I now insert a 1kc wide roofing filter, THAT has become a limiting factor. I should discern no difference (other than, perhaps some audio) between using a 2kc wide 2nd IF filter and a 1kc wide 2nd IF filter in a qrm-free environment. If I encounter single signal QRM nearby to where I am listening, I can still narrow the 2nd IF (say again to 500hz) and achieve some improvement. So...if I get a K3 and (for cw) I use a 500hz roofing filter, I can still use the DSP to get narrower for any single signal, nearby interference. If I use a 200hz roofing filter (assuming all other factors could remain unchanged), there is no reason to use a DSP (2nd IF filter) any WIDER than 200 because it is already limited at the 1st IF. I can use the DSP to get narrower than 200 and then I will HEAR a difference. All of the above basically is dealing with single signal QRM. On a band without IMD, a 15kc wide 1st IF is fine. I use my narrow 2nd IF (or DSP) to remove local qrm. For me, the real purpose of the narrow roofing filter is kill the potential for IMD, not nearby, single signal qrm. There has been a lot of discussion here already about HOW the roofing does that. So...assuming that IMD is the culprit that we are trying to solve, I would simply dump in the narrowest filter possible which met my operating style. For example, during a DX contest, I have to tune the band beside just sitting on one frequency and running. For me, I simply can NOT tune the band with a 200hz filter; I like to (need to) hear what is coming up as I approach it. It gives me an advanced notice on whether to keep tuning or to slow down and stop as I hit the guys frequency. With 200hz, signals only pop into the passband. If you tune too fast you'll miss them. So I want to pick a roofing filter that is narrow enough to remove most (if not all) IMD while still allowing me to tune the band in the style I am comfortable with. And I don't think that tuning the band in 200hz steps is an efficient way to win a contest (or even to enjoy tuning the band). The same is analogous on SSB. Using a 200hz (or 400hz) roofing filter on SSB just won't work because the first IF is now narrower than the single signal. So I need something at least as wide as the minimum for intelligible SSB reception. This is why you recommend/offer a 6kc filter for AM and an FM filter for FM (whatever width that is). If the above is true, I want to use the narrowest roofing filter by mode that works for my operating style only when I am having IMD issues (some have said AGC issues also). My use of the word narrowest is key. What possible advantage is there to trying a filter a which is a little bit narrower? If it doesn't work, I still get IMD. If it works this time, will it work next time under harsher IMD conditions? During a contest, I don't have time or motivation to play around. I want works all the time (or 99%). So for me, it just seems way more efficient to go the narrowEST roofing possible by mode all at once. Meaning that I want a single roofing filter by mode. And with that single roofing filter, I can still narrow the 2nd IF via the DSP (to 200, 100 or whatever hz) depending on the local (by frequency) qrm. It's fine with me that you are able to offer for sale so many options, but I agree 100.0% with Bill (ZV) as to why you would do that. It would appear to be huge overkill and is an apparent source of confusion to the subscribers. And saying that the competition also offers an array of filters, but in their 2nd if is not quite apple to apples. I found that to be a bit misleading. I guess the price of the variable passband roofing filter will add a lot to the story. If some guys operate all modes then they POTENTIALLY could use a roofing filter for each: FM, AM, SSB, CW, digital, if, and only if, they encounter bad IMD conditions

[Elecraft] 8 pole vs 5 pole..I knew this would happen
Hi all: The notation below (previously posted) is referring to the final passband filter and NOT a roofing filter. You are trying to compare apples and oranges. I think you would be hard pressed to discern (in real use) a difference between the 200 and 250 hz ROOFING filter, except in LOSS (which will be compensated for later). Pesonally, for cw work, I think both of those will be too narrow for my liking, especially if I want to tune around the band and not have signals suddenly POP into the final passband (which I like to keep fairly wide). I want to hear what's coming! de Doug KR2Q I had 2 CW filters in my TenTec OmniV and did a lot of A/B comparing with them. One was an 8 pole Inrad 400 Hz filter and the other was a 6 pole TenTec 500 Hz filter. I had them both in the rig at the same time specifically to decide which one to keep. I was able to detect the steeper skirts of the 8 pole filter as well as the narrower passband, but the factor that eventually tipped the scales was ultimate rejection. The TT filter, had better ultimate rejection. Once I tuned past a signal, it went away and didn't come back. With the Inrad filter, the signal would drop quicker, hit bottom and then come back up. I could hear strong signals 6-8 KHz away. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] here is how to get a feel for a roofing filter
Hi all: I knew this would be a tough one for many (most). Try this on for size Imagine that you walk into a very large office space (the band), filled with desks and a hundred people working at those desks. You sit down at a desk in the middle of the room. At first, nobody is talking (everyone is tuning the band). You sit down at a desk in the middle of the room and you strike up a conversation with the person next to you (one qso on the band). You can easily hear them. Now assume that five other deskmates (hams) within the room (band) also start talking and that they are randomly distributed about the room (the band). Your conversation will likely continue without issue. But maybe, ONE of the other conversations if taking place only 5 desks (kc) away form yours. It's a bit annoying. What to do? Well, you would ask your conversation-mate to talk louder (run more power), move to another desk (qsy), or you could put up some walls around the four desks adjacent to you (make a big cubicle). This helps to shut out some of the adjacent conversation (you narrow a conventional IF filter). If another conversation strikes up only 3 desks away from you, you might compensate by making the cubicle even smaller - say around just your two desks (narrow the conventional IF filter even more). Now assume that everyone in the room is communicating verbally with another person. A few people are whispering to each other (qrpers), some are at normal conversation levels, many are shouting (KW), and some are screaming at the top of their lungs (you know who they are). You have already build the smallest cubicle possible, but the other 99 conversations are still audible. You can not actually understand the other conversations, but the noise (IMD) is clearly there and making it hard or impossible for you to hear the person you are talking with. What to do? One solution is to make a smaller room with the big room (add a roofing filter). You might build a sound-insulated, concrete room that is one-tenth of the original size, but housed within the big room. This must mean that there are fewer other conversations within ear-shot because there are fewer desks in the new sub-room. So...lets suppose that you now have your smaller room built within the larger room. You now discover that there are NO other conversations that are so loud that you can hear them. In fact, it is so quiet now, that you can even take down your cubicle walls (open up - widen - the conventional IF filter) and still hear your own conversation without any other noise (IMD). [By the way, noise here = IMD squeaks, pops, bleeps, boops, etc., not static crashes or ignition noise, etc] Let's go back to the beginning. If you are having your solitary conversation in the original GIANT room and then build a walled-off section (sub-room), you WON'T notice any difference because it was quiet to start with and making your private room (smaller part of the big room) had no impact. It is still just as quiet after the new walls are put up. In other words, you can NOT hear the difference that a roofing filter makes unless there are lots of other LOUD signals within the first (typically broad) IF. I can guarantee you that Wayne and Eric will get complaints that the roofing doesn't work because folks just don't understand it's purpose. They will say (and I'll take bets on this), I don't hear any difference whether I use the wide or narrow roofing filter. And they'll be correct. Hope this analogy makes some sense for you. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] getting a feel for roofing....CLARIFICATION
Hi all: I got a nice email from Bill (ZV) noting that my description was rather lacking in helping to define IMD. I fully agree. In fact, what I described was about as far from what IMD is as one can get. My intention was to describe how to envision (via analogy) what a roofing is and does. I think I did a reasonable job at that. But I did a horrible job of providing an analogy for what IMD is. So here is here is the briefest of descriptions, trying to fit it into my original room analogy. When two people talk at the same time (not part of the same conversation (qso), but 1/2 each of two different conversations (qso's), ie, different desk to desk conversations), imagine that their voices interact with each other in such a way that new voices appears in the aisles between the desks. Sitting at your desk, trying to carry on your conversation, you hear these voices (which you cannot understand because they are a mixture of two others) that cover up the voice of the person that you are trying to talk with. The louder the voices coming other desks, the higher the probability that a phantom voice coming from the place between the desks will be so loud that it will cover up the voice you want to hear. Sowhen the roofing filter blocks the voice of a really loud talker in a desk 5 desks away, it also blocks (removes the source of) that phantom voice, so you can now hear the voice you want to. You only need to block ONE of the interfering conversations, because then there is no mixing of voices and no phantoms can voices result. That's it. Not great and perhaps not that easy to follow either, but at least I gave it a shot. The important thing is that IMD is not either original signal by itself. It is the result of 2 signals combining and yielding a new signal on a frequency that defined by the original two frequencies (somewhere in between...also beyond). Hope this helps and did not actually muddy the waters. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] roofing filters - when to use them
Hi all: Well, Bill (ZV) gave a nice (brief) summary and pointed to a nice reference. Ten Tec had (maybe it is still there) some good info also, but specific to their radio...however, you can still use it to get a feel for a what a roofing is (and what it isn't). If you're a member of ARRL, go to their web page and search on Roofing Filter. Don (FPR) cited some uses which I am not familiar with (data), so no comment from me on that. I've commented directly to the source about my wonder at why one would want a variable roofing filter. As Lee said, one wide and one narrow is enough (at least for SSB / CW only operation). If I'm on CW and my radio is hearing squeaks, pops, and garbage due to lots of LOUD signals being in my passband (say 15 or 20kc wide on an old radio), I would not be able to do much...maybe cut back on the RF gain, add some attenuation, etc. However, if I could narrow the passband (the roof) to say 1kc, the likelihood of two (or more) very loud signals being captured within that 1kc is greatly reduced. If I use a 500hz roofing filter (assuming all other parameters could remain unchanged), the odds of having two (or more) other very strong signals there (besides the one I want to copy) is even less...hence less chance of squeaks and pops masking the signal I want to copy. BTW, the squeaks and pops = IMD Products. Of course, if there were that many LOUD signals that close together, I'd simply move (qsy) to a clearer (relatively) spot. Why in the world one would want to take the time to carefully or slowly adjust a roofing filter's bandwidth is beyond me. I would simply dump in my narrow roofing filter and be done with it. Either it works or it doesn't; why play around? This topic is of major concern to contesters, especially (mostly) on the low bands. I know...it is also of concern to Europeans on 40m even NOT during a contest...true. If you're not a SERIOUS contester or Low Band DXer (or data guy ala Don's description?), I have a hard time understanding why you'd want these narrow filters. Hey look, 2.7kc is pretty darn narrow compared to most of what is out there. Again (as had already been cited), even the IC7800 and FT9000 have a 3kc roofing filter as their narrowest (which I don't think is good enough for some CW situation). I would guess that for 95% of non-serious contesters, or non-low band DXer (and digital guys?), you'll be VERY happy with a single 2.7kc roofing filter for SSB and even for CW. For those who are used to IF filters, this is just not the same. You'll still have that with the K3twiddle the bandwidth any way you like (narrow). Remember, roofing filters are for CROWDED band condx FILLED with LOUD signals (with the digital proviso still there). And NOW, I'd like to say, I have no idea exactly how much MAGIC the Aptos boyz have included in this radio and for all I know (not having the radio, the specs, schematic, code, etc., they may have come up with something that voids all of the above. Wouldn't that be great! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
