[Elecraft] Softrock as K3 Panadaptor: Buffer Amp Needed?
Hi I've seen differing views on the need to use a buffer amp. in this application. Has anyone out there used Softrock successfully without it? Did you have to take any special precautions to make it work properly? I'm intending to use a 32.768 MHz /4 crystal.

[Elecraft] 2 Band K1 Dead - Help!
Hi All I bought a previously built 2 band K1 (80m and 40m) a few weeks ago. It's been going really well and I've thoroughly enjoyed using it... BUT This morning I wanted to have a quick listen/QSO before work and I went to tune up my G5RV on 80m with my Z-11 autotuner. Unfortunately I forgot to reduce the power before tuning (I normally tune up with 1W or less) and I hit the tune button with about 5W from the K1. It started tuning but after about 2 seconds, the K1 died completely and cannot be resurrected. I will have a look at it tonight but has anyone had a similar experience or have any ideas about where to check first? 73 Marc G0AZS __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Make that forty or so Ian if homebrewed rigs count :-) When using multiple offset auto split I find it useful to have the actual frequency difference between the transmit and receive frequencies displayed. If this display was available in a rig without any form of auto split, then setting VFO B to the desired transmit frequency quickly would not require any mental arithmatic before calling a DX station and before the cluster mob arrives, very important at 2 am! If this can be done with the K3, my apology for this suggestion. 73, Geoff GM4ESD __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Softrock as K3 Panadaptor: Buffer Amp Needed?
Alan, The Softrock receiver will work just fine with or without buffer amplifier. It will be the K3 that will suffer because there will be a strong signal injected into the 8 MHz IF (from the softrock local oscillator) which can activate the AGC and otherwise degrade the K3 receive characteristics. What that means is that you can try it out without the buffer amplifier, but I would not leave it permanently connected without the amplifier. There is also a gain consideration for the buffer amp to increase the K3 IF output level. 73, Don W3FPR ALAN GARD wrote: Hi I've seen differing views on the need to use a buffer amp. in this application.

Re: [Elecraft] 2 Band K1 Dead - Help!
Marc, You have provided very little information, but D10 can short if operated for a substantial period into a high SWR (its purpose is to protect the PA transistor). If D10 is shorted, it will produce a short on the DC input voltage. You can try removing D10 (and check for a charred T4 at the same time) and see if the K1 works into a dummy load - if so, replace D10 and enjoy. If the problem is not D10, I will need more detailed information for a 2nd guess. 73, Don W3FPR Marc G0AZS wrote: Hi All I bought a previously built 2 band K1 (80m and 40m) a few weeks ago.

Re: [Elecraft] 8 AWG adapter
Hi Julius: I'm using #8 in my mobile installation and had to get it down to a more suitable gauge for the APP connectors. I made a couple butt-joint connectors from short (1) lengths of brass 'hobby tubing' obtained at the local hardware store. I took a short piece of the #8 wire with me and selected the smallest diameter of brass tubing that would still accommodate the stripped #8 wire. I then cut two 1 lengths, inserted one #8 wire (stripped to show 1/2 of wire into the tubing, flowed more than ample solder in from the other end. Let it cool while I did the other conductor. Returned to tube #1 and heated it back up while gently inserting the 1/2-stripped end of my #10 wire (which does fit the APP 45A connector). Let solder set and cover with a 1-1/2 length of heatshrink and yer good to go! Works like a champ. I could have used 'real' #8 butt-join connectors, but they were too large and 'clunky' for my liking... the brass hobby tubing works great, and it'll handle well over the 20A-30A needed by most rigs and accessories. 73, Tom N0SS At 07:46 02/16/2009, Julius Fazekas wrote: I have some really nice 8AWG cable for my power line.

Re: [Elecraft] 8 AWG adapter
Hi Tom, I like it! May even have some suitable tubing on hand. Just out of curiosity, have you used the APP connectors from old UPS units for anything? We had a couple of units with fried boards and the connectors (and several other parts)) were just too good to dispose of :o) All of my power distribution has the same size APP as on the K3, KPA100, etc. I have a nice 50A adjustable rack mount supply I want to use about 10 feet from the operating position, so 8AWG seems to fit the bill.

[Elecraft] 45A APP Crimper
Looks like the Anderson P/N for the 45A crimper is 1309G3. Is there that much of a difference between it and the WMR tool? It appears that the Anderson dies may be of better quality and the leverage may be optimized for the 45A connector, where the WMR tool might be a compromise in order to facilitate three crimp sizes. At roughly USD $200 for the Anderson tool, that's quite expensive for just one APP size. Is it possible to simply swap dies between the 45A and 15/30A sizes and save on the expense of owning two ratcheting tools?

Those short #10 pigtails need to be very flexible. You can go to a car audio shop and by extremely flexible wire by the foot. If it almost fits the connector, snip off a few strands. The stuff I got is speaker cable but I use it for power leads. Very nice.

Re: [Elecraft] K3: Configuring N1MM to send CW
W0MU wrote: To key cw you will need some type of keying circuitry. You have to have a keying \ transistor to send CW. Not true with the K3, Mike. Unlike most other radios, the K3 accepts CW and PTT keying signals on DTR and/or RTS without any need for a keying circuit - see the manual p. 18, near the bottom of the left column. The N1MM documentation has not caught up with this. If you have N1MM Logger configured for CW on DTR and PTT on RTS on the radio control port and you set the K3's CONFIG:PTT-KEY option set to RTS-DTR, then the Logger will key both PTT and CW with just a straight RS-232 cable and no other connections. If you only want to key one of CW and PTT via this port (for example, if you key CW with a Winkey on a different serial port), then you can adjust the configuration accordingly (e.g. RTS set to PTT and DTR set to Always off, with the CONFIG:PTT-KEY set to RTS-OFF). To make this work, you must make the software and the radio configurations match, and you must do it in the right order. First, go into the N1MM Logger's Configurer and change the configuration on the appropriate control line(s) from Always on to the desired value (PTT or CW). After you have both DTR and RTS set to the desired values in the software, and you have made sure that there is a check mark in the CW/Other column beside the port you are using for CW, *only then* go into the K3's CONFIG:PTT-KEY menu item and set it accordingly. If you make the changes in the reverse order (radio first), the default Always on setting in the software will key the radio, just like putting a brick on the key. As a side note, although the N1MM Configurer suggests Always on as the default for DTR and RTS on the radio port, with the K3 it would be better to set these defaults to Always off - that way, making a change to the K3's CONFIG menu without first changing the software configuration will not result in a key-down condition. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3: Qick Split
Doesn't Quick Split assume the DX is -always- located a fixed number of kHz away from his TX'ing frequency? This is simply not the case, if this is what's is being lobbied for. If the DX is actually an exact 5 kHz up, there will still be a need to change of one's TX frequency involved on almost every transmission ... or should be ... if one is an astute DX'er. Do people actually simply go up five and blindly call? Really? K5D is an example ... they are spending hours listening DOWN. I've worked them this way on four bands so far. I did this when operating from there ... and other DX locations ... BTW. My most-used control in working SPLIT is the A/B button.

Re: [Elecraft] K3: Qick Split
Quick split is a single button that puts the radio in split and the other vfo split x number of KC's away. It just saves some button pushing. Obviously if the station is working a weird split then you still have to move the b vfo. It sets the B vfo to the same mode moves it up 5 or 10. Sets the transmit to B etc. I have no clue how the 7800 did it as I never owned one. A slip of the foot you may soon recover, but a slip of the tongue you may never get over.

The B vfo is not locked. You can still move it. Having the 2nd receiver in the K3 makes it easier. Believe it or not many users do not have the 2nd receiver. I rarely ever use it for CW.

At present this whole sequence relies on the operator doing all the right things, and then continuing not to do any wrong things. Errors are punished by major embarrassment (literally, world-class).

You have to have a keying \ transistor to send CW. Not true with the K3, Mike. Unlike most other radios, the K3 accepts CW and PTT keying signals on DTR and/or RTS without any need for a keying circuit - see the manual p. 18, near the bottom of the left column. The N1MM documentation has not caught up with this. If you have N1MM Logger configured for CW on DTR and PTT on RTS on the radio control port and you set the K3's CONFIG:PTT-KEY option set to RTS-DTR, then the Logger will key both PTT and CW with just a straight RS-232 cable and no other connections. If you only want to key one of CW and PTT via this port (for example, if you key CW with a Winkey on a different serial port), then you can adjust the configuration accordingly (e.g. RTS set to PTT and DTR set to Always off, with the CONFIG:PTT-KEY set to RTS-OFF). To make this work, you must make the software and the radio configurations match, and you must do it in the right order. First, go into the N1MM Logger's Configurer and change the configuration on the appropriate control line(s) from Always on to the desired value (PTT or CW). After you have both DTR and RTS set to the desired values in the software, and you have made sure that there is a check mark in the CW/Other column beside the port you are using for CW, *only then* go into the K3's CONFIG:PTT-KEY menu item and set it accordingly. If you make the changes in the reverse order (radio first), the default Always on setting in the software will key the radio, just like putting a brick on the key. As a side note, although the N1MM Configurer suggests Always on as the default for DTR and RTS on the radio port, with the K3 it would be better to set these defaults to Always off - that way, making a change to the K3's CONFIG menu without first changing the software configuration will not result in a key-down condition. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Sub Receiver jones...
...I am surprised that the K3 would not be able to do dual in band receive or dual watch as some would call it. Early in the design process of the K3 we explored various methods by which we could obtain dual receive capability. Such capability was a basic design requirement. Putting in a default dual watch system means an additional mixer and synthesizer while providing limited flexibility. A lower-performance second receiver would not stand up to the severe operating conditions in which we wanted the K3 to excel. Either approach would add significant cost to the basic radio, requiring people who did not want such features to pay for them while denying a high-performance second receiver option to those who might want one. In the end, we concluded the best approach was an independent, high-performance second receiver. The KRX3 is the result. It provides the same performance as the main receiver. It enables diversity reception. Users of the K3's diversity mode quickly realize its benefits when chasing weak signals. And the price is shockingly low!

[Elecraft] Using USB mode for PSK31 rather than DATA A
After all this discussion of power control in DATA A mode vs SSB, I decided to try using PSK31 with USB mode, rather than DATA A. I changed the MIC SEL menu item to Line IN and adjusted the ALC meter to 4-5 bars using the MIC GAIN control. The PSK31 power output appeared to closely match the K3 power setting. Unfortunately, I received horrendous feedback about the widthand IMD of my signal -- when I returned to DATA A mode, my signal width and IMD returned back to acceptable values.

Re: [Elecraft] Sub Receiver jones...
Another solution is to get an LP-PAN panadapter. This gives a great panadapter plus two PowerSDR receivers. This weekend I was able to monitor K5D on the K3 and/or the primary PowerSDR receiver and listen to (and watch) the pileup on the PowerSDR subreceiver. PowerSDR allows you to put the pileup in one computer speaker and the DX in the other. Pretty cool! I only wish that PowerSDR receiver un-muting after transmission was a little faster. There is a little too much pause there.

[Elecraft] K3, RF gain acts funny
Hi All, I have joined the ranks of K3 owners and bought a kit which arrived late last week. Got it assembled and working late last night. My K3 is equipped as follows 100w Second receiver ATU RX antenna/Xverter ports Filter 2.7 SSB (stock) 400hz 8 pole Appears to work OK but when I reduce the RF gain normally the S meter will increase as I turn down the gain. On my main receiver this does not work correctly. As I turn down the RF gain, CCW, the S meter increases until it reaches S4 and stops increasing. By ear the RF gain continues to be reduced but it acts funny. My second receiver works as you would expect it should where the S meter increases until it reaches 60 over 9.

Re: [Elecraft] K3: Quick Split
No flame intended, but it certainly doesn't take several keystrokes.

Re: [Elecraft] Using USB mode for PSK31 rather than DATA A
That's it - you must turn compression off, one of the virtues of DATA A is that it does this for you automatically. With compression off it should work fine. See pg. 31 of the K3 Owner's Manual where it says: Soundcard-based data communications can be done using LSB or USB mode. However, DATA modes offer several benefits not available in SSB modes. If you prefer to use LSB or USB, you'll need to manually set CMP to 0 to prevent data signal distortion...

[Elecraft] Deaf K3 after HI RFI
Hi I lost my RX this weekend in a contest I got several HI RFI warnings and its ends with a low RX. Do do hear strong station with low signals. There is no difference in strength if I use ant1 or ant 2. The main RX or the sub rx. So I guess there is an short or an interrupt in the RX circuit. The power output is OK on all bands, If I'm correct this means that the problems is before the bandpass filters since the power get true them. Any clue where to start looking at?

Re: [Elecraft] K3, RF gain acts funny
Dave, I had a similar problem. I hate to suggest this out of turn, because it involves pulling the front panel, but if you're game... Remove the front panel so you can see the three solder terminals of the RF gain pot. Look at them closely and confirm the solder connection is good on all three. If the connection looks bad, re solder it. On my K3 I noticed that the center pin did not look like the solder took to the wire. This may or may not have caused my problem, but it is worth a looksee, and may fix your problem. I'd be curious to know what you find. 73, Julius n2wn Dave Anderson, K4SV wrote: Hi All, I have joined the ranks of K3 owners and bought a kit which arrived late last week.

[Elecraft] K3 Mods - Unauthorized Shortcuts
I finally got around to installing mods in units #1361 and #2183. The latter only needed a few mods but #1361 (including KRX3) needed the following: K3 AF Mod (K3AFMDKT) K3 Synthesizer ALC K3 AF Output KPA3 12V Sense Front Panel Mike Circuit Rear Panel RS-232/Audio RFI Immunity These shortcuts (not authorized by Elecraft) worked for me in the following order: 1. I did the RFC47 part of K3 AF Mod (K3AFMDKT) first by removing the top and bottom front covers. As others have previously noted, it's possible to remove RFC47 from the bottom without removing the KRX3 to gain access to the top side of the board. I used a Radio Shack solder sucker to remove solder from the bottom holes but my existing RFC47 did not drop out the other side as some have reported. I used a fine point to push the leads down and then grabbed the RFC with needlenose pliers from the top side. Once RFC47 is removed, it's a simple job to install the new one in the existing holes on the bottom side. Later you'll install the resistors that go on KIO3 when you get to step 5 below. 2. While you have the bottom front cover off, you can install N8LP's R8/R9 mod to improve IF out sensitivity (see the LP-PAN Yahoo group files for more info) and also, if you have an older unit, the Hardware AGC and CW Keying Rise Time mods since they are in the same area of the RF Board exposed by removing the bottom front cover. When you finish, reinstall the bottom front cover. 3. To do the Synthesizer ALC mod, you add a 180k leaded resistor to the synthesizer board(s) mounted on the front panel. By carefully cutting and forming the resistor leads, it's possible to insert them into existing holes on the synthesizer board(s) and then carefully solder each end, making sure that the leads extending through the boards are not long enough to short to the front shield. In my case I also removed the top TMP cable from the left (KRX3) board to avoid the possibility of nicking it with my soldering iron. I felt this was much easier than removing the KRX3 and synthesizer board(s) per the instructions. CAUTION: If you're not sure this mod has been done, you'll need to remove the synthesizer board(s) to confirm that R10 on the board has not already been changed to 56k. With the boards in place, you cannot confirm this by measurements alone. I was sure my synthesizer boards had not been modified because of the age of my units. 4. Next I removed the left side cover (with the handle) to expose the back side of the front panel MIC connector. To install the Front Panel MIC modification, you need to ground Pin 7 by running an insulated wire from it to a nearby ground as shown in the mod instructions (right side of Fig 11). If you have a thin soldering iron, it's possible to do this without disassembling the front panel (which is a pain to reassemble). Confirm that you have not shorted any adjacent pins and also check the the center pin of the MIC connector shows a short to the outer shell. Leave the top and side covers off. 5. Now remove the KIO3 and install all the components as instructed in the K3AFMDKT, Rear Panel RFI Immunity and AF Amplifier Output mods. I found it easier to remove KIO3 with the side cover off after step 4 to avoid interference with a TMP cable going to the KXV3's IF OUT. After you finish the side and top covers can be reinstalled. 6. The 12V Sense mod can be done by removing the 4 screws holding the fan assembly and letting it drop enough to give you access to install the diode on the KPA3. The procedure above is NOT AUTHORIZED by Elecraft and you shouldn't attempt it unless you have the proper equipment (a thin ESD-safe soldering iron like the CSI/Hakko 936, good lighting, magnifying visor, ESD work surface, etc) and soldering experience. But it worked for me and might be of some help to others.

[Elecraft] To Crimp or Not to Crimp...
Every time a discussion of crimpers comes up, someone wonders if crimping is 'better' and whether they should buy a crimping tool. Here's the scoop: 1) Crimping does not make a better connection than soldering. A properly crimped connection is just as good as properly soldered connection. 2) Proper crimping requires a quality crimper and knowledge about how to use it correctly. Poorly crimped connections will force the current through a relatively small, higher-resistance part of the wire, producing heat and serious voltage drops. So why would anyone use a crimper? 1) In a production manufacturing environment where many connections must be made quickly, day in and day out, crimping is much, much faster than soldering. The time savings quickly justifies the cost of the relatively expensive crimping tools. 2) Crimping does not require the assembler know how to solder, a significant savings to many manufacturers in labor and training costs. 3) In some situations (but not ones in which Elecraft rigs are normally used) soldered power connections are not allowed. These are generally situations where extreme short circuits could produce enough heat to melt the solder in an environment where the molten solder could do serious damage. 4) A crimper is faster and easier when working away from the bench, especially when portable soldering equipment isn't handy or one is working in tight quarters inside a vehicle or equipment (under the instrument board of an automobile, for example). This seems to be the main justification for buying crimpers I've heard from Hams. The Bottom Line: Elecraft emphasizes soldering APP connectors in their documents because: 1) Most Hams are experienced and equipped to solder, but lack the experience and tools for making good crimped connections. 2) The time saved by crimping becomes meaningless when making a small number of connections, especially in a workshop environment. 3) A good crimping tool is a significant expense.

The 12V Sense mod *recommends* only removing the fan panel assembly. No further disassembly is needed. All of the procedures are written with one key point in mind: showing how the job can be done with common tools in the safest possible manner. The goal is to avoid someone smoking a part, causing damage to a board or creating hidden damage that requires troubleshooting and additional repairs, all in the interest of trying to save a few minutes in the first place. The procedures in the assembly manuals and modification documents are tested on actual equipment with that goal in mind. Certainly, there are many ways to do most things, based on an individual's experience, tools and preferences. Sometimes that's covered in the document, such as when we show making a circuit change using either SMDs or leaded parts.

Re: [Elecraft] Using USB mode for PSK31 rather than DATA A
Steve, With my K3 , i use USB for PSK31 and i've set the button PWR to 100W, the LINE (rear line input) to 50 and i adjust the output level of my sound card with Tune mode of Digipan (a ~ single tone) to get ~ 50W average output; during PSK31 transmission, i've an average output power between 15 and 25 W depending upon transmitted text. Sometimes, i do a little adjustment by lowering the audio drive to NEVER get an average output power over 25W (measured with LP-100A with a SWR = 1.4:1 and 1.1:1 on the K3 (ATU ON) ) I do test with a 2nd instance of Digipan running with a 2nd TX/RX (FT857) and a 2nd sound card; i get an IMD between -24 and -28dB; it should be a little better ON AIR, because i've a little proximity effect with my Winter antenna at only 3 meters from my FT857at the balcony. Anyway, these values are not too bad and are a little bit better than the average of received stations (between -16 and -24dB). 73 QRO de Rudolf, HB9ARI PS May be it's not the best setup, but it work for me and i announce a 25W to my correspondents. steven.zabarn...@notes.udayton.edu wrote: No I did not turn off compression.

I have had numerous crimped purchased cables fail because of a lousy crimp job covered up by heat shrink. - That's why I'm a strong believer in strain relief, especially wherever a cable flexes a lot or vibrates. No matter how the joint is made, if a wire is allowed to move at the transition from flexible wire to rigid contact, the metal will crystallize (fatigue) and break at that point. I've always found that using proper strain relief and support for the wires which assures that movement - including vibration - is spread over a length of the wire and so no at one spot prevents breaking - at least in this millennium. In work on aircraft and military vehicles we always ensured the wire could not move where it connected to the pin, no matter how that connection was made: screw, crimp, solder, etc. People familiar with power systems have told me that the reason soldering is not used (and illegal in many situations) is that wiring can get hot enough under extreme conditions to actually melt solder. If that happened, the resultant poor connection left once the solder is gone could heat enough to start a fire or melt the wires, all without drawing enough current to open the protective breakers. That can be catastrophic in many environments, not the least of which is inside the wall of a home.

Re: [Elecraft] K2 stacked over KAT100
John, In the KAT100 kit, there are 2 anti-slide brackets PN E100150 that mount on the top rear of the KAT100 enclosure. The projections on these brackets fit into the recessed holes in the rear feet of your K2. Page 30 of the KAT100 manual shows how they are mounted. If you ordered the KAT100-2 (the one that mounts in the EC-2 enclosure), those brackets are not included. Normally the KPA100 is mounted in the EC-2 with the KAT100, and the K2 should not be stacked on top of that assembly because it restricts the air flow. 73, Don W3FPR John Wiener wrote: Hi I don't recall where I saw this but I think someone posted a smart way to keep the K2 from slipping slowly off the back ot the KAT100 while hitting the buttons.

[Elecraft] K3 Mods
I really don't want to delve into my K3 with a slodering iron and a baggie full of bits and pieces. So how about Elecraft offering a board swap for those of us who do not wish to do the mods themselves. Interestingly enough I sent this request direct to Elecraft and as yet I have had no reply. Australia is quite a long drive from Aptos and the cost of posting the whole radio back to the US is a costly option. I for one would simply sell the radio instead and think about a repalcemnet rig later if the hardware revisions were needed to the point where the radio was unable to do the job it was purchased for. This is not the case of course as the K3 has performed flawlessly to date and has exceeded my humble expectations, bit having said that, I would like to bring it up to the latest specs with the mods that are now included with the current shipments.

Great tip Val, and one I will try! Of course that only works if the station is up 1. Other splits aren't covered. That's where a the quick split feature really comes in handy. Hold the split button, and VFO B synchs with the VFO A frequency; enter the split by hitting the proper number on the keppad, and VFO B is there. Yes, rotating the knob works, but when you're tired and trying to calculate up X, it just takes longer to get there. The early bird gets the DX, and quick split really helps.

[Elecraft] Not so Quick Split please
Well I'm guess I now qualify as an old timer with an analog mind that works well unless there's too many tap dances during the feeding frenzy of a DX pile up. Split operation when searching to spot the QSO with the DX station can give me a red face after I call on the DX's frequency. Not so cool! As a new K3 user I find there are two paths to follow when in this mode of operation. Split with RIT/XIT on VFO A This approach makes it easy with only VFO A set on the DX station and spotting by tapping RIT, finding the station working the DX, down or up, when found then a tap on XIT button followed by an RIT button tap gets me back to the DX station with TX split on the last QSO and ready to roll. Sounds simple and quick? Not so safe! Sometimes I find myself transmitting on the DX frequency in the frenzy. There are too many taps in this dance step for me and it brings on the over zealous self appointed police with all their powers to send .._ / ._ _. and/or ._.. / .. / _.. Oh my! sorry. The RIT/XIT combo dance is too complicated. I'm going to go sit down. Split RX on VFO A, TX on VFO B Alternative I've decided this alternative is safer and reduces the posibility of sending cw on the DX frequency. Spoting the QSO before sending requires two taps on the A/B button. But quick taps in the Split mode may also result in sending on the WRONG VFO or on the DX operation frequency. Thus my first suggestion after two months with my sweet K3. May I suggest to the Elecraft staff that a Human engineering change be offered for the 60 yo as a reward for being licensed over half a century. This special feature requires a K3 with a frequency TX inhibit feature that can be set for the DX operation frequency before the tap dance begins. Or should it be called Safe Split rather than Quick Split?Get it? Don't get me wrong I love the radio but I have too many quick controls :-( 73, John, W1QS, ex N6JL (76-08), K1KTH (59-76) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 - Another feature request
OK, since everyone is voicing their desires for K3 features, here are mine. Let me start off that when not working HF, the K3 sits on my 6 meter repeater frequency, and gets a lot of use there. I have discussed with Wayne in the past about CTCSS decode and reverse phase burst on CTCSS. I was thinking with that nice keypad doing nothing on TX that when in FM mode, it could send DTMF tones. I would like it, but who else might, I don't know. Maybe something for the way back burner. The K3 appeals to a wide range of users for various reasons. The 6 and 10 meter FM is what sold me on the K3. Some of us like FM DX and working distant repeaters when the band is open. I know I like hearing distant voices come in on my machine. 73 de Josh K6ZRX __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: Quick Split
Agreed ... several previous rigs in this shack had quick split options and after playing with it for about one day, the option was routinely disabled. It was simply too easy to wipe out what I had set on the subreceiver/VFO B and I could get to the DX station faster manually. Now, if someone wanted to request that a hold of XIT would both turn on XIT and set it up 1 on CW and up 5 on SSB, that might be useful. If a hold of XIT while XIT was enabled would move the transmitting frequency and mode into VFO B (or A-B would put the TRANSMIT frequency into VFO B if XIT was enabled) that would also be worthwhile. 73, ...

As a test, I set my sub-receiver to 20m SSB and my main receiver to 40m CW (I'm beta testing the software for independent receive). All it took was to tap A - B, hold the SAME BUTTON for split, and spin the VFO B knob to be ready to go for a split transmission on 40m CW. It took less than two seconds for everything. It almost seems like some forethought by Elecraft went into the choice of buttons to use ;) I bet it would take at least two seconds to cycle through a few stacked fixed offsets (say 1/2/5 KHz) by holding the split button multiple times.

Re: [Elecraft] SPLIT
Colin, You might have VFO B in the wrong mode. Try doing AB twice, then go into split. If this doesn't work, try loading the latest beta-test firmware (2.82). I'm sure we tested split on each release, but this rev might have a relevant improvement. 73, Wayne N6KR On Feb 14, 2009, at 12:30 AM, Colin Potter wrote: Hi all, need help! Using ver 2.78 ser 2014.

Some DX operators (the ones I like) go through a pileup in one direction, moving up or down a discrete amount each time. Then they either 'snap back' to the other end of the pileup, or tune back the way they came. This is the best case, because if you are thinking you can predict where to call accurately -- and only a small percentage of callers are thinking! Others hop around between two general areas. You can imagine them flipping back and forth each time. If you detect this, it can be helpful. Some operators pretty much listen in one spot, plus or minus a few hundred Hz. for a long time. Pretty soon everyone learns where this is! Sometimes a guy will just randomly pick someone to answer with no discernible pattern. This can be frustrating. You really do need two receivers to spot the pattern. It can be hard when the DX is working stations that you can't hear. I know that I have spent long periods in pileups without results until I get the pattern. Then -- blam, one shot.

Re: [Elecraft] full 70cm band coverage possibilities?
Changing the IF of the XV432 is not difficult from a design standpoint, but requires careful testing with test equipment not found in most hamshacks. A new crystal would be needed in the Local Oscillator and there may be possible changes in a couple of the LO filter components. Next the IF filter would need to be redesigned to cover 50 to 54 MHz and then, finally, the XV432 output spectrum would have to be looked at with a spectrum analyzer to assure that all spectral purity requirements been achieved. The K3 cannot cover the range from 30 to 32 MHz because of a bandstop filter that has been included to suppress 6 meter image responses. 73, Bob, N6CM On Mon, Feb 16, 2009 at 6:56 PM, Doug Faunt N6TQS +1-510-655-8604 fa...@panix.com wrote: How difficult would it be to modify the XV432 to use a 6M IF?
