Ralph Parker wrote: I held my kit until the KRX3 was ready. I could be wrong, but I'm under the impression that a sub-rx add-on only needs to have the front panel removed, not dis-assembled. I have had no trouble at all with the second rx - works as advertised and I'm happy. To fit the sub-rx you have to remove the front panel, take off the dsp board and fit the auxilliary dsp board. It then goes back on. I have fitted (and in one case back engineered and refitted) 3 sub-rx's now with zero problems. The only reason I had to back engineer one was for a problem that occurred that was nothing to do with the sub-rx. I always recall Elecraft telling us that the sub-rx required some work on the radio and as it got closer they also showed us it in photographic form. The point is the fit is straightforward. If you built the K3, it is almost trivial in comparison and works really well! The K3 is a 'kit' and occasionally you might have to do some work on it just like the K2. In fact some of the stuff on the K2 (like the 60m board) required some mods to the main rf board. My advice to anyone contemplating the sub-rx fit is just to do it. It enhances the radio and is not difficult to do. Your enjoyment of the radio will increase, especially if you have a vertical and a horizontal aerial for the same band in diversity mode! 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC DX Cluster Member RSGB, GQRP K2 #4044 |K3 #455 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: [K3] Text decode with straight key - OT now
Hi Ron, I'd completely agree with that, having used G4FON's excellent Koch trainer to get started, I found copying my mentor's Morse a little difficult when I first started and he sends very good Morse on a S/K. But after a little while, I got better at it. I'm up to ~ 8 WPM with him now. I need to listen a lot on the bands now and try to copy, so I'm not completely blown away by a different fist. Oh and I've taken on board something both he and someone else I spoke with in JOTA at the weekend have repeatedly said - just have Morse playing in the background, the brain absorbs it, in the same way we first absorb human speech when we are a baby. Lastly, why am I saying Morse all the time and not CW? Because I feel CW has the connotation of transmitted Morse via carrier wave (a mode), were as Morse means the 'code', but maybe not transmitted, maybe played from a recording. - Feel free to correct me. 73 de M0XDF, K3 #174 -- I don't mind that you think slowly but I do mind that you are publishing faster than you think. -Wolfgang Pauli, physicist, Nobel laureate (1900-1958) On 21 Oct 2008, at 04:04, Ron D'Eau Claire wrote: IMHO, if someone wants to be really proficient at reading Morse, they need to practice, practice, practice reading a variety of not-so-perfect manual fists.

Re: [Elecraft] Re: [K3] Text decode with straight key - OT now
My advice is to send as well as receive. Get a short automatic recording of something repetitive at a speed you are comfortable with and send along side it - mimicking the code that you hear. This is a good way to build up a good fist. I used to copy a point to point station that sent its long call sign over and over. Get someone else to check your sending and compare yourself to automatic recordings. Sending reinforces the characters into your memory by another route. Then try sending without paper in front of you; just common stuff like your rig and QTH, name etc. Once you are on the air and getting your feet wet with live contacts, you don't have stuff to copy, you take it direct from the brain. That's quite a jump forward and you need to prepare for it. As a beginner on air, you can have a card with salient points you often mention in your QSOs but you dispense with that when you've done it often enough.

Thanks David, yes, been sending too, both to my mentor, G3NCN (he sends a char or a word, I tell him what it is and send it back) and also sending text (normally the contents of a page-a-day calendar for yesterday :-) via an oscillator to an MFJ code reader - that is very unforgiving, so my sending is apparently pretty good and improving daily.

There's a ready market for K3s and I suspect you could sell your existing unit for at least what it cost you, and probably closer to what an assembled unit costs if you've done it carefully. I really enjoyed building my first unit, but decided to build another from scratch when the KRX3 became available. I may do the same if I ever decide to add the KDVR. I'm quite sure I could install these options after the initial build, but I simply enjoyed the build process so much I chose to build my KRX3 unit from scratch.

Re: [Elecraft] K3 - KRX3
"I originally planned to wait and see how other installations played out especially after reading that the front panel had to be removed and messed with in order to do the KRX3 installation. That's the last thing I wanted to do." Removal and re-installation of the front panel assembly is quite easy if the instructions are followed. That said, due-diligence rests with the builder/purchaser. If there's any doubt about the kit's degree of difficulty, the answer is only one phone call or e-mail message away. I would argue that if there's concern and fretting over a retrofit, then a K3 in kit form is not in the best interest of the prospective purchaser.

You could run one loop to RX ANT (for the Main RX) and the other loop to AUX RF (for the Sub RX), if you wanted to listen in multiple directions simultaneously. This would allow you to choose either your TX antenna or the RX ANT loop #1 for the Main RX and AUX RF loop #2 for the Sub RX. Alternatively you could run both loops to AUX RF using an external switch. What you need for best diversity reception is two "diverse" antennas...either different directions (e.g. your 2 loops) or different polarizations (e.g. a vertical and a dipole). With proper switching you can even do both. 73, Bill -- View this message in context: http://n2.nabble.com/K3---KRX3-tp1358071p1359535.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I've never heard an "SE0" before and my brain/ears were trying to make sense of it as I was madly switching antennas to try to peak the signal. I first thought it was an "NE0" so I was switching my antennas West. Unique prefixes are not always an advantage if the operator on the other end does not recognize them! Here in the USA it can also be confusing if a station is not in the direction indicated by the number in their call (since you instantly lose the signal if they are not in the expected direction of your RX antenna selected). I also have the 2.7k and 500 in both RXs for diversity, but additionally have the 1.8k and 200 in my Main for serious contesting. I've found that even using the 200 in Main and 500 in Sub does not cause serious problems in diversity, even though the filters have different offsets...but this might not be the case for everyone. 73, Bill W4ZV P.S.

[Elecraft] OT: KP5 and 60m
It is announced that the upcoming DXpedition to KP5, Descheo Island, plans to use 60meter band. This is a mistaken use of this band because 1. it was justified to FCC to be awarded to ham radio as an EMERGENCY BAND, not a DX band. 2. it wil obviously be overloaded in the extreme, having nearly 24 hr openings to the States, leading to sigs out of the sliver bands as ops desperately try to be "a little off freq" to get the DX's attention. 3. It gives casual ops another reason to condemn DXpeditions because, in this case, the whole band is likely to be occupied with KP5. This is the biggest zoo of all time waiting to happen. It is no accident that ARRL currently sez it will not credit award contacts on this band.

Re: [Elecraft] K3 - KRX3
Hi, Dave, Wow -- I know exactly what you are talking about! I received my KRX3 and there it sat in a box for two weeks. I was more than a little scared to install it after reading about some of the horror stories on the reflector. Two weekends ago I took the plunge. I set aside an entire Sunday, cleared the work bench, and dived it. I have to say, quite honestly, that it was much, much easier than I could have imagined. I think being a little scared might have helped, as I was VERY careful and took my time. However, it all went together ridiculously easy and I had no problems whatsoever. The front panel was much easier to get off and reinstall than it was the first time I put the K3 together. In the entire process, the only problem I had was a bent screw. The decision is yours, but I wouldn't hesitate to do the install again. Good luck and 73 . . .

What kind of characteristics does it need? 73 Matthias hb9egm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Tolerances of RF Chokes K2 (6291)
Hello I am building up a K2 with great pleasure. Now I have wound the RFC 14 und 16. If I measure the Inductance with an AADE (and compare with a second instrument) I get 29 uH for the RFC14 and 78uH for the RFC 16. In the Manual are the values 18uH (RFC14) and 47uH (RFC16). The deviation is about 50-60%. (The number of turns are correct and spread out to 90% of the toroid) My question: Why is this difference so big? Is this the tolerance of AL? Is it correct that this differences are not crucial for the purpose of this rf chokes?

The inductance of a coil wound on a toroid core depends on the frequency of measurement, because of the properties of the core material. I don't know what frequency the AADE meter uses, but it may not be the same as the frequency at which the chokes are spec'd. If the chokes are wound properly on the correct cores, they will work properly. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 #6602 build: AGC question
Marinus, The most likely reason you cannot achieve 3.8 volts is because the 8 volt regulator output is a bit low. Set the AGC Threshold to 45% of the 8 volt regulator output BUT no lower than 3.65 volts. Actually, you can set it lower, but the S-meter setting can get a bit 'squirrelly' at lower threshold voltages - the choice is yours that is why the AGC Threshold was made adjustable after SN 3000, it used to be a fixed value. 73, Don W3FPR Marinus Loewensteijn wrote: Assembly part I completed.

Is this due to different tolreances fo the parts or have different IC's been used that create this discrepancy? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] High SWR problem
All has been fine with my K3 until today. The display is indicating "High SWR" when I transmit on SSB. The KAT3 indicates a 1.0:1 match, but the when I transmit the swr meter is high and I get the high swr message on the screen. If I turn it down to 5 watts and send a tone with Digipan, the swr is fine, but turn it up to 100 watts and the swr is back up. Nothing obvious has changed, the antenna is 2:1 on my analyzer with no tuner. If I bypass the antenna tuner, the bar graph meter on the K3 shows about 2:1. But if I switch in the KAT3 and tune, it indicates 1.0:1 but when I transmit it's high. I've swapped coax jumpers between the radio and the antenna with no difference. Thanks for any suggestions.

I didn't read the reflector for all of the horror stories, but I didn't install mine right away because of work - the same reason I checked out of reading the reflector for a while. I finally did it a couple weeks ago, and did find it to be rather involved - but at no point did I feel like I was out of my depth. I don't consider myself the most mechanically able guy by any means. I will admit that when I saw that the front panel had to be removed, I did groan a little. I remembered that the initial assembly and install had been kinda gnarly. But the instructions were very clear and you only have to remove the items that are strictly necessary. A lot less trouble than I feared! By the time I was done I realized that, in a way, by doing all of the necessary disassembly and removal and re-installs, it was kind of like getting to build another radio.

[Elecraft] Help with distorted [K3] transmit audio
Today using SSB on 40M my K3 came up with pinched audio, the other operator asked me to take the "clothes pin" off my nose. Full (and good) audio was obtained with a power cycle. I was told that signal strength came up significantly after the power cycle. I have posted this issue four times now. The problem doesn't surface everyday. I had thought my problem had something to do with HRD or use of the Elecraft K3 utility as in the past these had been used before the condition arose. But today I started the rig in the morning after a longish shutdown while I attended Pacificon. I did not use HRD or the download facility this morning so I no longer think that using those programs is involved with my this problem. The audio sounded like all highs in the monitor headset. The usual suspects have been looked at like the Tx equalizer and filter set up, that's what everyone has said to look at every time in the past. One and only one action is performed to bring the audio back to full and that is cycling power. I believe this fact rules out most set up issues. I suspect a firmware bug but it seems strange that I am the only target. Pinched audio could mean that the SSB signal isn't centered properly in the pass band of the 2.7 KHz Xtal filter, the rig is trying to transmit through the 500 Hz filter or the DSP is improperly initialized. Is there a relay contact that could be intermittent that could cause these symptoms, like one that switches in the 2.7 KHz filter? I have seen the same audio distortion using front and back microphone connectors and with two different microphones, one electret with bias the other dynamic without bias. Both microphone setups will get good audio reports after a power cycle. I run 13.8V from a 35 amp linear Astron power supply. Voltage drops to 13.1V with 100W key down so I don't think there is a marginal power supply condition. I have 13 KHz, 6 KHz, 2.7 KHz, and 500 Hz filters. SSB is only enabled on the 2.7 KHz filter.

Re: [Elecraft] K3 - KRX3
I can just confirm that after 4 hours job on kitchen table without any complication I have new KRX3 module inside, calibrated and with all filters I ordered for it. Also DSP f/w loaded, simply finished. There was no horror scenario, board fitted inside correctly, no need to modify R91 etc Also having version without nylon standoff for main DSP but suppose it is used as mechanical support only to avoid touching boards or some long leads problems which is not my case. There are basically three main "actions" as KSYN and SUB I/O boards and AUX ant cable install, then Front panel DSP addition and KRX module itself - you can plan and study all from manuals just before and ask for anything unclear, really there is no trap or hidden beast inside :-) Dissasembly/assembly of DSP BD and Front panel was not done first time here so maybe I am little bit more experienced but really no problem. The more iportant challenge was to fasten AUX ANT Bnc and organize coax cables around PLL... Now connecting antenna and will test split on VK9WDX on 30m :-) GL to all K3 builders, thanks to Elecraft and 73!

I don't consider myself the most mechanically able guy by any means. I will admit that when I saw that the front panel had to be removed, I did groan a little. I remembered that the initial assembly and install had been kinda gnarly. But the instructions were very clear and you only have to remove the items that are strictly necessary. A lot less trouble than I feared! By the time I was done I realized that, in a way, by doing all of the necessary disassembly and removal and re-installs, it was kind of like getting to build another radio. Which was a real and unexpected treat! Hope this helps! jeff wk6i ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 - KRX3
The filters don't need to be matched in bandwidth but they do need to have the same frequency offset to avoid possible "beat note" problems between the two (main/sub) synthesizers. I didn't bother to pay the extra 60 bucks to frequency-match the 2.7 kHz in the KRX3 with the old one in the main receiver. The new one came in 100 Hz different than the old one, so I just split the difference and entered the same offset for both. A 50 Hz error is not significant in a 2.7 kHz filter.

[Elecraft] K3 at KH6LC in Stew Warmup
Aloha,
Considering recent posts, maybe you would be interested to hear about
the setup we used at KH6LC during the Stew Warmup. I brought my K3 SN
469, which has 2.7, 1.8, and 0.4 filters in the main and matched 2.7
and 0.4 in the sub. Now I know that I should have sprung for the other
1.8 filter and saved myself the labor of installing it later. Thanks
to the stamina of Ken N6KB we have two beverages, one roughly in the
JA direction and one slightly east of the US mainland direction. The
transmitting antenna is a shunt fed tower. We decided to try for
maximum flexibility, so we put the tower on ANT1, the JA beverage on
RX ANT IN and the US beverage on AUX RF. With the appropriate
configuration via the front panel this put the signals from the
mainland in the right ear and the signals from Asia and Alaska in the
left ear, and if we wanted to try the vertical it was a single button
push to get it. Occasionally a signal would move from ear to ear! The
beverages aren't really very long, the longer is about 450 ft, but
they are surprisingly directional. I think it's fair to say that this
setup made a positive impression on all of us and now we want Ken to
slog through the jungle some more to put in more and longer wires.
The roofing filter mismatch between 400 Hz and 1800 Hz bandwidth was
sometimes noticeable, but it wasn't a big thing. One mod I would like
to see would be an option to have the subreceiver bandwidth and shift
track the main as it's an aggravation to have to double click the A>B
when you want that. Of course, you would like the option of having
them separate, too.
This K3 was the subject of a post last week ("Bad CW Note") and I can
report that this problem seemed to us to not be present last weekend,
but those of you who heard us may tell a different story and if so I
would be happy to hear from you directly. In between the post and the
weekend, I had partly disassembled the case to look into putting a
strap directly from the antenna tuner RF ground to the rear panel
connectors, but I decided I didn't have the time to finish so I just
replaced the panels, and maybe that improved the ground. On the other
hand, we did get bad reports on the CW keying. One report said that
it sounded like the keying was "soft". Another report said
"distinctive, but not fatally obnoxious". It appears now that this is
a problem mainly with the computer keying from the rear panel jack,
and not the CW generated from the internal keyer, and that it may be
connected to the TX DLY setting that I had at its maximum value to
accommodate my old TL922 linear. I have backed the setting off to 15
and the CW weight looks more consistent on my scope now. At KH6LC
there is a modern linear and the nominal value should be enough. We
are still looking into this and also the buzz on the note and the
story may change.

Re: [Elecraft] [KAT1] 1N34 Diode replacement
I don't know if we're talking about the same diode. The broken diode is not in the bridge used to measure fwd/rfl power. I'm talking about D3, connecting the output of the buffer op-amp U2A to the RFDET/DATA pin on P2. I don't know what it's for (what is RFDET/DATA ? I don't have the K1 schematics right here). I suppose I'll use a low-drop schottky, like 1N5711, thanks to everyone for the advice 73, matthias HB9EGM Tom Hammond wrote: > Matthias: > >> The 1N34 diode on my KAT has its glass broken.
