[Elecraft] K3 Software
I just uploaded K3_EZ, a Windows application I've written for the K3 (Apologies to K3EZ!). It provides: * A set of 5 'memory-like' frequency storage areas per band and mode * A frequency and mode database, useful for SWL frequencies * A graphic interface for the K3 RX and TX equalizers with a database for storing favorite settings, MIC Gain, Compression, and setup notes * 4 panels of information containing the majority of the K3 CONFIG settings with 'one click' access to any of these for you to easily make changes The application should run on WIN 98SE and up as long as Microsoft's .NET Framework 2.0 or later is installed on your PC. (See this http://msdn.microsoft.com/en-us/netframework/aa569263.aspx for the latest info on MS .NET Framework) You can download K3_EZ here: http://home.roadrunner.com/~n2bc/ follow the link for K3 Software Comments, questions, etc (bugs?) to me directly please: n...@stny.rr.com 73, Bill N2BC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: Transmit when switching from DATA to AM mode?
Weird Had the VOX gain at 60, changed it to 40 and it's OK now. Set it to 100 and it's still OK. What's weird is that there was no mic connected when it was acting up. I had also unplugged everything except 12V power and a dummy load and it failed every time. Seems that simply changing VOX gain did the trick.

Re: [Elecraft] No On/Off for COMP EQ?
There has been much chatter about the K3 EQ lately. I've written a small Windows application that helps to 'manage' the equalizers. This is a work in progress, and I'm not much of a programmer. You should take this to mean: Caveat Emptor! The application is being used by about 20 people now and I'm chasing a couple bugs. 1) It does not behave well when access to the K3 is via N8LP's LP-Bridge. This is NOT an LP-Bridge issue. There is no direct way to read the EQ settings other than simulating button presses and reading the VFO B area. The problem is that the EQ setting displayed on VFO B only appears momentarily and is then replaced with the 'label' for the EQ band. Because LP-Bridge is polling the K3, my app will sometimes miss the data. 2) The app is written in MS Visual Basic 2008 and requires ,NET Framework 2.0 or later. If your system does not have 2.0, it will be downloaded from Microsoft. While this is not in and of itself a problem, I do have one user that is having difficulty that looks like a problem in the Framework - something that may well be beyond my capability to resolve. You can peek at the application and download it here: http://home.roadrunner.com/~n2bc/SW.htm I'm looking for ideas for impovement - some are proposed on the subsequent web page. I am in the process of improving the overall communications error handling, improving the documentation, and looking at other ways to store the EQ settings. No timetable for these as yet. If this little utility is a help, great! I would prefer that any communications regarding the program not be on the Elecraft reflector, but rather direct to me.

Re: [Elecraft] K3 CW Keying via Serial Port?
FWIW, I've been using N1MM Logger keying via the serial port (and earlier via parallel port) since 'day 1' of Logger on many different PCs, WIN98 thru Vista, 'real' serial ports and USB-to-serial ports, on different YaeComWood rigs, a K2 and now my K3. It works just fine, always has. The setup via the K3 is easiest of all since it does not require any hand-made cable or level convertor/keying switch, just a quality standard serial cable. I'm not saying anything against the WinKeyer, never tried it, never needed it. 73, Bill N2BC - Original Message - From: WILLIS COOKE [EMAIL PROTECTED] To: Elecraft Reflector elecraft@mailman.qth.net; [EMAIL PROTECTED] Sent: Sunday, October 12, 2008 5:01 PM Subject: Re: [Elecraft] K3 CW Keying via Serial Port? Fred, you can get the K3 to key, but the timing available in Windows does not allow good CW to be produced. The Workaround is to purchase a WinKeyer USB from K1EL and insert it between the Computer USB port and the Key jack on the K3. This is a function of Windows, not N1MM or the K3. You can not get away from the problem by using different software or a different transceiver. The WinKeyer USB has its own microprocessor to generate the code and accepts the message to be sent in ASCII. The WinKeyer controls the timing. It is not expensive and is very small.

[Elecraft] K3 Equalizer utility
I've written a Windows utility to help 'manage' the K3 equalizers. It has a graphic display of the 8 EQ bands in the K3 equalizers, can read and set the EQs, and allows you to quickly set/save various setups along with relevant notes entered by you (mic type, gain settings, etc). The program has been tested on XP and VISTA and should work on WIN/98 and up if Windows .NET Framework 2.0 or later is installed (available from Microsoft). It has been tested on K3s at FW 2.38 through 2.46. The program installs via the Windows installer and is easily removed using Add/Remove Programs. I'm looking for a small number of folks (under 20) to use the program and give me feedback. If / when I make it generally available it will NOT be for a charge. Please reply directly to me if interested - not via the reflector: [EMAIL PROTECTED] If interested, please let me know the level of Windows and your K3 firmware level. I'd be happy to send a screen-grab of the main form and the documentation to anybody that's interested.

[Elecraft] K3 Memories - Band changing etc.
I miss dedicated band buttons even though my main rig has been a K2 for the last couple years. Using the Quick Memories and M1..M4 work quite well though. But (you knew this was coming), the very thing that makes the Quick Memory function handy can also be its downfall. Try as I might to be careful, I continue to clobber the memory by pressing VM in error. Because the 00 - 09 locations are Quick Memories they are overwritten immediately when the numeric keypad entry is pressed. I would like to see either: 1) A menu entry to disable Quick Memory function for storing (VM only). In other words when disabled, storing would require a second VM keypress just like the rest of the memories. or 2) A menu function to LOCK the Quick Memory areas. This would require changing the menu entry to QUICK or NORMAL before entering anything in the Quick Memories. or 3) A combination of 1 2 to give the 00-09 locations a selection of QUICK / NORMAL / LOCK. I'm sure there are many contest operators that will use the Quick Memory function during the heat of battle. A menu approach would not take anything away from that use. Just my $0.02. By the way, I grew up on DX-35s, Apaches, Drake 2Bs, HQ-170s etc etc ,even with an occasional AW s^$ when I clobber a memory, band change is a whole lot quicker! 73 all Bill N2BC Now all we need is a few sunspots! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: Perfect K3 Speaker
Wayne, I'm curious about what seems to be an emphasis on non-powered speakers in your reply... why? My op bench was getting overrun with speakers for various rigs. I picked up an 8 channel stereo line level mixer and now run everything through a single set of powered PC speakers. The mixer (Behringer RX-1602) automatically mixes mono inputs as L+R and has a separate level adjustable stereo headphone output. Each input can be individually switched on/off. I did have to make a handful of isolation transformers to get rid of some ground loops but the mixer powered speakers tolerate legal limit RF levels well. 73, Bill N2BC (checking every email now, waiting for my Katie-gram on a December K3 order!) - Original Message - From: wayne burdick [EMAIL PROTECTED] To: Bruce Osterberg [EMAIL PROTECTED] Cc: Elecraft Reflector elecraft@mailman.qth.net Sent: Saturday, May 03, 2008 11:43 PM Subject: [Elecraft] Re: Perfect K3 Speaker Hi Bruce, For communications bandwidths, a sturdy 4-ohm, 3 or 4 diameter mobile speaker (non-powered) does a great job. For a bit more fidelity and to take advantage of the K3's stereo speaker outputs, I use a pair of good quality bookshelf-style speakers (again, non-powered). Right now I'm using Best Buy's Insignia, 4-inch, 3-way surround speakers, which sound quite good, although they're 8 ohms rather than 4 so the available per-channel peak power will be lower. They're about 4W x 8H.

Change the power level - now there is normal output! In fact, if I recreate the setup (freq to 25000.00 or higher, tap the key, get END), then change to any other band - there is no output until I change the power setting. I couldn't find this mentioned in any of the archives. Is the firmware getting confused or do I have a unique gremlin? The only reference to the END msg I can find in the book is CAL PLL. It's working 100% otherwise. Would appreciate it if somebody else would give this a try!

[Elecraft] K3: Hardware changes
My, my... Here's what I propose. All you folks that are disappointed that there may be a change in their K3, please send Lisa an email and ask her to put your order on hold until the K3 stabilizes. I would love to get bumped up in the queue. Further more I hope you never get your K3. Why, because I hope it never stabilizes. As the K3 'product line' gets fleshed out - you know, things like panadapters, linears, ??? - there will likely be lots of changes. If this is 'scary, if the changes are kept 'secret', then I guess you can wait for the K3 PRO 4, or the K3 Mark 7G3. Secret' is what YaeCOMWood does! Now, lets all get back to discussing important things, like the K3 color.

[Elecraft] K2: Low power out on 12M 10M
K2 # 6254 Only abt 1W out on 12M, 5W out on 10M. Worked FB when I assembled it last fall. I've been all over the 12/10M bandpass components with fresh solder. I went through TX alignment found 20/17/15/12/10 all improved - but only ended up with the above power levels for 12/10. I have not compared voltages band-to-band at the bandpass output yet, will drag out the scope tomorrow. Then I'll look at the 12/10 LP filter area. Any other quick-hitters I should look at before I pull the bottom rear cover?

Re: [Elecraft] electronic product standards
Mic 'standard' - never happen - at least I hope it never happens. They started out with one pin for audio and could end up with one pin for everything as more and more 'brains' are moved into the microphone and the connection to the radio turns into a one-wire serial link. This could give us a compatible connecter with completely incompatible 'data streams'. Break out your wire cutters and soldering iron. Visit http://www.qsl.net/g4wpw/date.html to view the myriad of pin-outs for and within each of the manufacturer's microphones and radios. If we need a standard, I propose that it be based on a 14-pin JONES plug, that would look pretty nifty on the front of the future K4. OK, /sarcasm off I'll go shovel the driveway. 73 Bill N2BC ___ 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: KRC2 interface
Hi Don, Do you mean the K3 AUX I/O Pin 10 KEYOUT-LP line? The purpose of this line is a bit fuzzy, to me anyway. I based my KRC2 'needs' list based on page 21 of the KRC2 manual. The paragraph at the top of the page states that the minimum required for a K2 are: W16 - AUXBUS W18 - 12V (can be provided via external source) W19 - 8R W21 - to pass PC serial info to K2 (not needed in K3) W23 - ditto W21 Table 3 states that the KRC2 uses 8R to determine TX/RX status, I would have thought to inhibit band changing while transmitting. I just tried the KRC2 without feeding it 8R from the K2 (W19 pulled). 8R is indeed not 'needed' to handle the band info from the AUXBUS. Tried changing bands on the K2 while key down or asserting PTT - it won't change. But the K2 remembers the band change key press and does change once key down or PTT is dropped the KRC2 follows. Anywho, it looks like the K2 is smart enough to not change bands while in TX the KRC2 will follow the AUXBUS as/when ordered. I'm sure the K3 is at least that smart [ ;-) ] So I amend my KRC2 needs list to simply AUXBUS and ground - GREAT! 73, Bill N2BC - Original Message - From: Don Wilhelm [EMAIL PROTECTED] To: Bill Coleman N2BC [EMAIL PROTECTED] Cc: elecraft elecraft@mailman.qth.net Sent: Wednesday, January 30, 2008 9:48 AM Subject: Re: [Elecraft] K3: KRC2 interface Bill, The KRC2 does not need the 8R input for use with the K2 or K3.

[Elecraft] K3/10 Power levels
I've got a K3/10 with a KXV3 on order. I have a vintage military amp that only needs 100 to 150mW of drive. I've studied the RX antenna options provided with the K3 and KXV3 but still have questions: Can I reliably set the output power at the 100mW level (band-to-band) ? Ideally I would like a dedicated 100mW level TX output and a separate dedicated RX input. I think the separate RX input is possible via the KXV3 but it bypasses the front end bandpass filters. Is that correct? I think another approach could be to run the amplifier off the KXV3 output at 1mW bumping it up with a broadband amp to 100mW. RX would then come in through the normal ANT connection. Yes? Right now I have a second antenna transfer relay on the amp input which switches in a 30dB attenuator on TX to dump the 100W output of my transceiver down for the amp. I can simply replace the 30dB attenuator with a 20dB or 15dB and run the K3/10 at 'full' power. But with separate RX and TX on the K3 and reliable 100mW output control, I can eliminate the second transfer relay and the attenuator. Thoughts?

Re: [Elecraft] K3: supplied power cable specs?
but.. the K3 is a no solder kit! Sorry... I converted my shack and a couple op positions at our club shack to APP's - soldered dozens of them, works great. One tip: make sure of the orientation of the connector pins before soldering especially on heavy gauge wire. This can be a bit tricky as the pin will want to rotate on the wire as soon as you touch it with the soldering iron (Murphy at work). It's important so you don't have to twist the conductor to get the pin into the connector. Also the little APP insertion tool is quite handy for small gauge wire. So now we know, there are two solder connections on the K3 kit!

This was an issue with the early Orion also. As I understand it, PTT in CW was eventually implemented on the Orion. Some of the contesting software will raise PTT and delay a user specified time before keying to let the T/R switching settle. Also, on all the YaeCOMWood rigs I have used, releasing PTT returns to RX 'instantly' - cancelling any delay set for semi-breakin. Not having a QSK amplifier, and not particularly caring for QSK at all, PTT in CW capability is important to me.

[Elecraft] Resistance checks - check your meter too!
Just did a quick scan of the K3 assembly manual - wonder how many downloads so far..?? !! The following will likely apply to the K3 also - I'll find out next year for sure. I'm at the end of day one of assembling my second K2, just finished the Control Board. Used my trusty (old) auto ranging Fluke DMM to perform the resistance checks and went down the tubes on the 8V regulator output, measures 500 ohms - should the 3 to 4 Kohms. To make a long story short be careful. I did a simple test with the Fluke connected across a 3K resistor - my handheld DMM says the Fluke is applying almost 0.5V. Flipping the meters, the handheld DMM only applies about 60mV - and the 8V bus resistance check is fine measured on the handheld DMM. Clearly the Fluke's 1/2V is on the hairy edge of some of the active devices on the 8V bus. It's interesting that the lead polarity makes no difference in the resistance measurement at all. Now I'll carefully read the K3 assembly manual, then start the K2 front panel. Hmmm... I wonder. Nah, I'll still end up with a K2. 73 all, Bill N2BC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] KPA100 (or K2) Power control
I'm having a difficulty with the power control in a freshly built KPA100. When I set the power to 50W then key up (TUNE), I get appx 25W (indicated on the K2 and external wattmeter). If I barely move the POWER control on the K2 output will jump to 50W indicated on both the K2 and wattmeter. Each TUNE cycle is the same. I'm not sure if the problem is in the KPA100 or my K2, as the K2 is not very 'stable' either. With the KPA100 disabled I set the K2 to say 5W, then enter TUNE, I get appx 7W output (indicated on K2 and wattmeter), minor touch on the POWER control will drop the power to 4W, exit TUNE and it says 5W. It behaves this way with the KPA100 set OFF or with no PA PS or completely disconnected. Confused? Well, I am! The bare bones K2 overshoots it power setting, with the KPA100 it under achieves. :-) All of my testing has been done with a known good dummy load. The 'problem' is not band sensitive. How 'stable' should the K2 POWER settings be - if I set it to 5W should I be seeing 5W indicated on the K2? I thought that under a good load condition the firmware would 'match' the requested power and actual power within a few tenths or so. I figure the K2 needs to be fixed before I fiddle more with the KPA100 - yes? Now the hard questions... what, where, why is the sky blue? (wanted to have one easy question!).

I'm building K2 #5290. Have made it through the second session on the RF board (Assembly Part II). The VCO freq is wrong The PLL Ref Osc range is 12098 to 12084. I'm seeing a stable 12445 on the VCO (TP1), VFO set for 4000.1. I've eyeballed the RF board carefully with a magifying lens didn't find anything conclusive. I looked at U4 with a scope and am not sure if I'm seeing my bug, have my setup wrong, or the voltage chart is wrong. U4 pin 5 (SDO) is zero and goes high (+5) with pulses on band +/- (measurement chart says +5) U4 pin 7 (SCK) is +5 and goes low with pulses on band +/- (measurement chart says 0) Given that the MCU can 'move' the PLL Ref Osc, that pretty well says that the SDO and SCK lines are OK, right? All the rest of the pins on U4 look reasonable per the measurement chart. I've double checked L30, T5, D23-D26 I suspect I'm barking up the wrong tree with the SDO and SCK lines... Where next? Thanks! 73, Bill N2BC PS: My first big kit was an SB-100 in 1965 I think. It's first power on was much more dramatic than the K2. Smoke curling up from the chassis. A hunk of miniature coax carrying low B+ was shorted. That's when I figured my homebrew power supply should probably have some fuses ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Minor kit building tip
I've just started building K2#5290. Thought I would pass along a small building tip. The search function of the current Adobe PDF reader is quite handy for finding things in the manual. Example 1: Having just finished populating the caps on the Control Board, I noticed the spot for C44 was empty. A quick search of the PDF manual on C44 took me to page 21 and explained that C44 is unused. Example 2: At this point I had expected all the non-electrolytic caps to be mounted, but I had one .01uF (103) left over. Since I had done a thorough inventory, I figured I screwed up. A search on 103 eventually took me to page 20 and the added C46 for the keying shaping circuit on the bottom side of the board. A caution... after finding your info in the PDF manual, double check with your errata marked-up paper manual! Anyway, the search function saves a lot of time flipping pages - and is undoubtedly more thorough than scanning with tired eyes. It works on the schematic pages too!

[Elecraft] K2 #5290 Underway
#5290 arrived today. I've enjoyed reading the reflector for the past few weeks, hope to 'contribute' in the future. In an effort to eliminate any possibility of a haunted K2, I will hang some garlic over the workbench before I heat up the soldering iron. Happy New Year to all 73, Bill N2BC K2 #5290 as soon as I stir all these parts together! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 minimum power our
I'm considering a K2. The power out spec says .5W... how much less? I'm not much of a QRP op, my amplifier only needs 100 to 150mW. If the K2 will reliably go to 100mW or less I can skip inserting an attenuator and simplify T/R switching.
