[Elecraft] K3: pseudo KRX3 free via LP-Pan+Power SDR
RE: http://www.youtube.com/watch?v=4tjKQ1g4X0I Great video and demo. I have not ordered the KRX3 for either of my k3 radios. I do contesting as 99% of my ham activity (not counting posting on the Elecraft reflector), so I saw little need. However, the LP-Pan is on my list. After viewing the video, I am happier than ever that I didn't get the KRX3, so this alternative will be more than good enough for the extremely rare occasion (for me) when I'd like to use a sub-receiver. Of course, I can always use the 2nd K3. ;-) Great stuff guys! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Dual PB filter
Anybody out there playing with this feature or actually used it in a contest? What are your experiences? Playing with it yielded the following:. 1) Narrower CW filters can't be used (at least not my 400 Hz and narrower filters). The wings are outside the narrow filter passband. 2) For me that meant the 1.8KHz roofing filter was used. It seems like that defeats the purpose of having a K3. In a contest situation, I would certainly like as many rock crusher signal outside the roofing filter passband as possible. It would suggest one might consider the 1 KHz roofing filter, if you want to seriously use this option. If there existed some intermediate (say 700Hz) or variable roofing filter, what would it's width have to be to include the wings and be used for dual PB filtering? de Brian/K3KO -- View this message in context: http://n2.nabble.com/Dual-PB-filter-tp642132p642132.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.

[Elecraft] K3 Assembly issue with bottom Heat Sink cover!
Hey gang, Just spent 4 hours assembling K3 s/n 1318 and all went well except for one slight but potentially serious hardware problem. When installing the bottom heat sink cover over the LPA I noticed that the required 4-40 x 1/4 screws bottomed out in the standoffs under the TO-220 LPA transistors before they would compress the cover to the transistors (and yes I can measure screw lengths). This will leave a gap between the transistor and the heatsink and not provide proper heat sinking! It is strange to note that one of the Manual Errata changes was to point out that the heat sink cover was slightly thicker than the other bottom cover. Wonder if this part has changed? Any way, I added 3 #4 stainless steel flat washers under the screw heads and that allows the screws to fully compress the heat sink against the transistors. For a belts and suspenders fix I also added a dab of heat sink compound to the transistors as well. I did not check the screws coming from the top side of t! ! he LPA assy to see if the factory may have used the wrong/longer screws taking up extra standoff threads. A #4 split washer could have also been left off of this top side screw and create the same issue or tol. stack up of the parts?

RE: [Elecraft] K3 Assembly issue with bottom Heat Sink cover!
Rodger, I assembled my K3 a couple of weeks ago (s/n 1217), and did not experience your problem. The three transistors clamped nicely against the (thicker) bottom cover using only the hardware specified in the instructions. As I recall, there are both 3/16 and 1/4 screws in the kit. You sure you've used the correct screws everywhere? Took me about 10-11 hours to assemble my K3 (100W).

Re: [Elecraft] [K3] SUB RX and Calibration quesitons
Very interesting video. Couple of questions. 1. The SUB RX. If I check the box I do get the blue passband but it doesn't move when I turn the small VFO knob. Did I understand that is a coming attraction? I can move the blue passband with the mouse and hear the second RX. Is this really a poor-man's KRX3? Seems with the LPPan you are getting the benefit of a single conversion RX (post roofing filters) and DSP filtering but it is not a true copy of the main RX like the KRX3. As I think about this, listening to both VFOs through the LPPan/SDR combo is bypassing the second IF and the DSP filtering in the K3. 2. I still have trouble understanding the synchronization of the pandapter to the K3. The vertical red line seems to be the tuned frequency + the sidetone but a CW signal appears to be sitting in the middle of the passband which is up another 650hz. I can adjust the IF Frequency Global offset to the sidetone frequency to put the CW signal on the red line. But, when I switch to the other side (CWL to CWU for instance) the signal is offset. Is this normal? Buck k4ia K3 #101 **Get fantasy football with free live scoring. Sign up for FanHouse Fantasy Football today.

[Elecraft] CAUTION Re: [K3] Eterlogic VSPE 0.80
One caution about using VSPE courtesy of N8LP below. Do not connect any other programs when running K3Utility for firmware updates. It's possible that the firmware update files could be corrupted by other programs attempting to access the K3 during the update process. Larry does not even allow LP-Bridge to access to the K3Utility to avoid any potential problems. 73, Bill http://groups.yahoo.com/group/LP-PAN/message/1019 Re: [LP-PAN] Re: LP-Bridge and PowerSDR v0.92 alphas released Hi Bill. I block the K3 Utility commands. There is a mention on the LPB web page to not use K3 Utility. I don't think it's safe to flash firmware with more than one program connected to the K3. VSPE is like LP-Bridge with all filtering disabled (ie, all ports connected to the serial port, and vice versa). I would not use Utility with VSPE unless it's the only application connected to VSPE at the time. There are many situations I found in my testing of several other port sharing programs many months ago where I had problems with polling commands colliding, and causing missed commands and ignored commands by the K3. Also, if all commands are returned to all programs, any program without an asynchronous event driven serial implementation will get very confused by all the unanticipated traffic. LP-Bridge isolates the responses so that a program wont see anything it didn't poll for unless you check AI1 or AI2. This is generally done for programs which don't poll.

Re: [Elecraft] Dual PB filter
Just looked at what this Dual PB filter was doing with SPECTROGRAM. Set up with a width of 600Hz and a 1.8 KHz roofing filter. DPB off and on. The 600 Hz alone has the normal filter passband shape. DPB on gives a narrower center filter less than 200 Hz wide and two augmented wings down about 30db filling out the rest of the normal filter passband. This explains why DPB sounded quietern to one poster. I suspect turning the K3 width setting to 200 Hz would have the same quieting effect. 73 de Brian/K3KO David Wilburn wrote: It has really saved the day on a couple of RTTY QSO's.

Re: [Elecraft] Using Voice Files along with Mike Input on a K3
Ed . If you look at http://www.writelog.com/support/wlso2r.pdf it shows how to set up the mike for SSB contesting. If you ignore the Left Rig and the W5XD Multi+ keyer and just look at the Right Rig and microphone setup you will see how to keep the audio from the other ops out of your mike. In N1MM configurer you can select the line to mute when playing wav files. This is also mostly the Mic input. Check http://pages.cthome.net/n1mm/html/English/BasicFunctions.htm#Recording_Wav_files for recording info. I have found that if the MON level is turned up so you can hear yourself, with MIC + Line in you will get feedback when you activate PTT. I'm assuming this will not happen if the mike is plugged into the sound card. Also, if you want to record both TX and RX audio in the contest you have to select =PHONES. This will send TX RX audio to the sound card at a level controlled by the AF Gain control (NOT Line Out level) and possibly overdrive your sound card. 73HankK8DD - Original Message - From: Ed Steeble [EMAIL PROTECTED] I tried to use a K3 in the IOTA contest on SSB but ran into a problem.

Re: [Elecraft] K3: new demo video with LP-PAN panadapter and powerSDR
The LP-Bridge software is now available, and that provides an extremely powerful environment for the K3 and the panadapter. For example, you can now run CW Skimmer and Writelog at the same time and have them share access to the K3. Another example is to use your logging program (I use DXLab) together with PowerSDR and your K3. The LP-Bridge software allows you to share the serial port and work seamlessly: Click on a signal in PowerSDR and it changes the frequency on both the K3 and the logging software.

[Elecraft] [K3] #1361 just arrived!
I originally ordered my second K3 in September but asked for it to be held until both the KRX3 (ordered May 1 last year) and KDVR3 were available so I could build a new unit from scratch with all options. EI6IZ's diversity recordings and comments finally got to me and I couldn't stand it any longer, so I asked for delivery sans KDVR3. I'm now thinking I may cancel the KDVR3 in lieu of using the internal DVK in N1MM for 10m contests, which is about the only time I use SSB nowadays. I decided to take my chances with XFIL offsets (i.e. by not ordering them matched). Apparently I lucked out: MAIN: 2.7k -.84 500 -.78 KRX3: 2.7k -.81 500 -.78 I'll split the difference on the 2.7k filters at -.82 or -.83 (after carefully measuring both) and the 500s are good as is. Just for interest, here are my offsets for #111: 2.7k -.97500 -.79200 -0.90 I'll move the 200 to the new unit but not use it in diversity mode, and I may add a KAT3 to my older unit to use it for portable/expedition use. Now I've got work to do! 73, Bill -- View this message in context: http://n2.nabble.com/-K3---1361-just-arrived%21-tp660692p660692.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.

RE: [Elecraft] Dual PB filter
Two different filters although both are activated by the DUAL PB hold-button, depending on MODE. In RTTY it is the Dual-Tone Filter, two 50 Hz DSP filters spaced 170 Hz apart. In CW, it is a two level filter with two widths, 150 Hz and 600 Hz as I recall. The passband of the 600 Hz filter is 20 dB down which provides the skirts to hear nearby signals without having them dominate the signal(s) you focus on in the 150 Hz filter. As for the choice of roofing filter, it needs to be wider than 600 Hz. So, yes, a 700 Hz crystal filter would give the most DSP protection from strong signals outside the 600 Hz bandwidth. 73, Ed - W0YK -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Wilburn Sent: Wednesday, 30 July, 2008 05:37 To: Elecraft Discussion List Subject: Re: [Elecraft] Dual PB filter It has really saved the day on a couple of RTTY QSO's.

Re: [Elecraft] Re: K3 6m pre-amp
Bob, While I cannot speak from my own measurements, but in EMRFD, Wes Hayward recommends the U310s for VHF/UHF rather than the J310. The case of the U310 is connected to the gate, and when used in a grounded gate configuration, the case can be mounted (upside down) into a hole in the PC board, and I believe that alone should provide better input to output isolation. The Vishay data sheet indicates a slightly lower noise figure for the U310. I would suggest that you try the J310s. If you find them lacking, it should be easy to change to U310s, I would guess that at 50 MHz, it may be a 'toss-up' decision. 73, Don W3FPR Bob Tellefsen wrote: Hi John I've been looking at this circuit for some time.

Re: [Elecraft] Re: K3 6m pre-amp
Don: The U310's are not too easy to find these days. Vishay seems to be the most common (only?) new production supplier and the one-off price is about $14 from Mouser or Arrow. Digikey, Allied and Newark only stock the SOT23 plastic surface mount version. TO-92 plastic case parts, the J310, are around 25 cents each. The U310 and J310 are supposed to have the same die, so differences should be attributed to the case, but who knows what goes inside the package these days, particularly if it is from China.

Re: [Elecraft] Re: K3 6m pre-amp
Jack, I understand the vanishing part syndrome. I have a few remaining in my parts bin, and I am not about to give them up (similar feelings about my dual gate MOSFETs). As an alternative to the U310, when laying out a PC board (or Manhatten construction board), one might consider the SMD version of the J310/U310. It should be at least as good as the U310 and likely better. A nice clean layout is critical to performance in a VHF/UHF amplifier. A carrier board may be needed for Manhatten construction, but for 3 legged devices, a carrier board is simplicity itself - just a tiny scrap of rectangular PC board with the copper cut in half along the length and one of the remaining long rectangles cut in half across its width. Caution - cut the copper on the corner of a larger piece of PC board and then cut out the result as the 'final act' - attempting to cut through the copper on a tiny board can result in injury to the fingers and hands. With the demise of thru-hole parts and the advent af inexpensive SMD parts, we hams will have to learn how to deal with these tiny devices if we are to continue homebrewing and experimenting efforts at a reasonable price. 73, Don W3FPR Jack Smith wrote: Don: The U310's are not too easy to find these days.

Re: [Elecraft] K3 ATU
Chris, The KAT3 (like other Elecraft tuners) is an L network type tuner, and should provide good efficiency. For your particular situation, I suggest that you use something like the TLW application (from www.arrl.org) and calculate the L network configuration needed for your impedance range. TLW will also give you efficiency numbers. The 'fact of life' that deals with added loss due to signal routing on the PC board should be minimal, but if you add 5 or 10% additional loss to account for the physical mounting of the components, you should be 'in the ballpark'. Yes, you will have to know the reactance before you can obtain the really correct answer. L network tuners are generally more efficient than the common Tee type tuners, but I am generalizing here, and exceptions are always present. The PI network is typically efficient too, but the output capacity required becomes very large at low impedances. If you want real efficiency, consider a link coupled tuner (like the Johnson Matchbox), but you sacrifice convenience for improved efficiency figures - the link coupled tuner does not lend itself well to bandswitching or to an auto-tuning application except over a very limited range (one ham band or less). 73, Don W3FPR Chris G3SJJ wrote: Does anyone have any figures on efficiency of KAT3 for load impedances of 20 and 200 ohms?

Re: [Elecraft] Re: K3 6m pre-amp
I'm using J310 parts in a VLF-LF-MF-HF active antenna design I'm working on, no need to go to the U310 version at those frequencies. I've found best intermodulaton performance in the active antenna requires 25 - 35 mA idle current with 8-10 volts source-drain, so there's some advantage in rated dissipation with the U310 part. Another used-to-be-common part is a 2.5 mH RF choke, pi wound on a ceramic form. After a lengthy search, I found Hammond still makes these, only to learn that they were discontinued earlier this year. I managed to get one (at a price of $14) and it's good that I only needed one to use as a comparison reference for a QEX article I'm working on.

Re: [Elecraft] K3 6m pre-amp
Yes, I have several ferrite core 2.5 mH chokes here, including the Hammond one you mention. There's a significant difference in high frequency performance of the pi wound on ceramic form versus the smaller pi-wound over ferrite and that's one of the things I'm hoping to illustrate in the article. Hence, I needed a genuine 2.5 mH National Radio style choke. Jack K7TV wrote: Try Antique Electronic Supply (www.tubesandmore.com).

[Elecraft] Problems with K3 KXV3 IF Output Level?
Good evening Lyle: I honestly don't know where you're getting those levels from as I already reported to you back in April/08 that the levels at the I F output were pretty well non existent. There is just no tracking of levels at the I F out with what is fed into the antenna input of the receiver. I even used a 15 db amplifier from Jack Smith of Clifton Laboratories without any luck as there is simply no levels to play with there. I believe that Jack Smith also queried you about that without getting a proper reply as yet from you. I realize that nobody is perfect but why are we dogging a proper reply and/or fix for that?

RE: [Elecraft] K3: pseudo KRX3 free via LP-Pan+Power SDR
The IF output from the K3 is after the mixer but before the crystal filters. So one advantage of using the KRX3 is that you get much better dynamic range due to the crystal filters. It probably doesn't matter much for casual listening but for contesting and DXing the KRX3 would have much better performance. However, it sounds like the PowerSDR receiver would make a nice spotting receiver, just to get an idea of what is going on on a frequency. The ultimate DX station would have a K3, KRX3 and PowerSDR. The main receiver is on the frequency of the DX station you are listening to, the sub-receiver is on the pileup frequency, and the software receiver is available to quickly check out any other interesting pileups you notice on the panadapter.

RE: [Elecraft] K3: pseudo KRX3 free via LP-Pan+Power SDR
The part that confuses me is the mention that [PowerSDR] fully integrates with the KRX3's main and sub RX frequenciy on its panoramic display. Thats what it does now. But in order for the KRX3 to actually be adding anything you'd have to be listening to its output with the full K3 filter chain. Cause you're not going to correct the dynamic range problems unless you're doing that. Then I don't see how it could allow you to be more than 192KHz/2 away from your main center freq as you'd have to have two sound cards and two IF outputs in order to pull that off. I guess I don't really see a SubRX adding much to the PowerSDR setup unless you use one RX as a spotter and the other as simply a K3. I think that 2 K3's would be a better setup for that. I see the subRX in the K3 as a way to make the K3 a better unit as a standalone unit. Which I think is one thing that the K3 does really well especially since you can make RTTY/PSK contacts with just a K3 sitting on your desk and nothing else. You can also run it as a contest station for both CW and SSB (once the DVR is out). I find it quite fun how much one can get done without the need to interface it to a computer. Now don't get me wrong I'm a total computer guy and I find it even cooler that while it does all this stuff to not require you to have a computer it also makes is SOOO easy to interface to one when you decide you want to. So I guess all in all color me happy yet still confused as to the KRX3 adding much to a powerSDR setup.

Re: [Elecraft] Using Voice Files along with Mike Input on a K3
I completely agree. I was excited when I saw a recent release note that said that TX audio would be available on the LINE OUT connector, but then was disappointed to read further when it said it was controlled with the front panel volume control and not at a fixed level. Can we PLEASE get this to a fixed level so that we can record both sides of the QSO without worrying about the FP volume control, and so that it also works with digital modes (RTTY, JT6M, etc) correctly?

It would be very useful in contests to record both sides of a contact CW or SSB. 73 Stewart G3RXQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
