And we're still short several key parts, so we won't ship on the 17th. :-(
I'm waiting for replies from several vendors and will post as soon as I have good information. I'm beating on them as hard as I can.. :-) 73, Eric WA6HHQ --------------- Thom LaCosta wrote: > On Thu, 13 Sep 2007, Don Rasmussen wrote: > >> We're four days from the target date for the first K3 >> delivery and performance numbers are being released. >> What could this mean? ;-) > > That there really are K3s, that there are measurements and Santa Claus > has gainful employment. > > 73 - k3hrn > Thom,EIEIO > Email, Internet, Electronic Information Officer > > www.baltimorehon.com/ Home of the Baltimore Lexicon > www.tlchost.net/hosting/ Web Hosting as low as 3.49/month > _______________________________________________ > Elecraft mailing list > Post to: [hidden email] > You must be a subscriber to post to the list. > Subscriber Info (Addr.

Eric, If you want someone else to beat up on the vendors...just list their names here on the reflector. I am sure they will then be flooded with phone calls. Better yet, if those vendors need help in getting their products to you, maybe we can mobilize some "K3-owners-to-be" to quickly arrive and expedite matters. My field of expertise is quality control and quality assurance. Any of those vendors near NC? 73, Henry - K4TMC Raleigh, NC -----Original Message----- From: Eric Swartz - WA6HHQ, Elecraft <[hidden email]> To: Thom LaCosta <[hidden email]> Cc: Elecraft <[hidden email]>; Don Rasmussen <[hidden email]> Sent: Thu, 13 Sep 2007 5:42 pm Subject: Re: [Elecraft] K3 specs And we're still short several key parts, so we won't ship on the 17th. :-( I'm waiting for replies from several vendors and will post as soon as I have good information.

Hey, u want to beat up on the vendors? Better get an air ticket because
lots of parts are not MADE IN THE USA anymore, if ever. for example, people ask me "how can u take medicine there in Thailand?" Answer, my meds come from same place as urs in usa.... India, China, and some other less savory places. And what about the knock-offs? Remember the sub-standard metal bolt crisis of 25 yrs ago? Those bolts are "holding up" USA bridges today, eh? Anyone want to announce the "contry of origin" of most electronic parts today? Who out there actually knows, speak up. 73 Charles Harpole, HS0ZCW [hidden email] _________________________________________________________________ More photos; more messages; more whatever.

Gosh, Henry -- I don't think you thought through the political-economic
dynamics here. :-) The vendors in question must be single-source on these parts, or they would have been back-up ordered from a secondary source and there wouldn't even be an issue. If these vendors get all kinds of calls from Elecraft customers, they will darn well KNOW they are single-source, and then who's in the cat-bird seat? They are! You don't want that to happen. You want your vendors to believe you can always order from somebody else. If they know they have you over a barrel, they can jack the price up and drop you to the end of the queue with impunity.

I am at the 40-meter transmitter alignment stage in Alignment and
Test, Part III. It instructs me to "Place the K2 into tune mode and activate the built-in wattmeter by holding "TUNE". Using the alignment tool, adjust L1 for maximum output." And, do the same with L2, etc. etc. etc. First, I'm going into a 50W dummy load/Wattmeter (MFJ 267). And I have my Cal Curr setting at 2.0, and Power is set to 2.0 as well. I also have the radio set to 7100 for freq. When I put it into Tune mode, I get a reading of "P. 0.2" or P. 0.3 through 0.4 It will flicker back and forth across those three values whether I turn the tap on L1 or L2 or just leave it completely alone. At the "info triangle" at the start of this section, it says "you'll place the K2 into TUNE mode by holding TUNE." However, if you "hold" the button in it makes no difference from what happens if you just hold it in long enough to activate the P. 0.2 (etc.) display.... I do not have a key plugged in, so I obviously am not keying anything at the time of tuning...but it did not state you needed a key attached, and I presume putting it into Tune mode is "keying" the radio anyhow....which may be an incorrect presumption...heck if I know. I went into the trouble shooting section, and it appears I need to be looking at Problem 150 through 160.... The resistors are correct, the Diode appears to be correct (so small I can't read any numbers on it, but it checked out at the time of installation and is oriented correctly., I've not been able to find any shorts, the Transformers T1-T4 are wound as per part III of the assembly section. I've not checked the DC voltages because I cant' find in the manual what they should be reading or whether to check with power on or off and have reached the end of my patience for the evening and am not certain I'm even on the right path... Any direction would be appreciated. This build has checked out on every step to date...but I'm stumped.

Hi
You must set the power control to about 1/2 scale and hold the tune button to get into tune mode then as you tune L1 and L2 as the power comes up readjust the power pot up or down a little to make the MPU re-measure the power. You should reach a point where L1 and L2 will peak. If this does not work and you got a peak when doing the receiver test earlier then you have a problem in the transmitter somewhere. Usually a bad solder joint on a toroid or a missed solder joint. Look at the relays it is easy to miss pin one on the relays as they look like feed throughs Don Brown KD5NDB ----- Original Message ----- From: <[hidden email]> To: <[hidden email]> Sent: Thursday, September 13, 2007 11:13 PM Subject: [Elecraft] K2 alignment confusion...

Thank you Don.
I got the peak at the earlier receiver stage. I have also gone back over the solder joints and all the relays three times since last night with nothing spotted. I'll comb through the toroid connex again... Adjusting the power with the front panel "power" control while in Tune makes no difference...and neither does moving L1 or L2. dk Quoting [hidden email]: > Hi > > You must set the power control to about 1/2 scale and hold the tune button > to get into tune mode then as you tune L1 and L2 as the power comes up > readjust the power pot up or down a little to make the MPU re-measure the > power.

Hi
To help any more we need some measurements in the transmitter. Did you build the RF probe and go through the troubleshooting section of the manual? What test equipment do you have. A scope would be nice but the RF probe/multimeter should be good enough to find the problem. Basically you start at the transmit mixer and check each stage following looking for a loss of signal. 70-80% of the time the problem is a toroid wound wrong or a toroid lead not tined properly and not making a good connection to its solder pad. I will be away from my computer for a week so I can not give you any more help but if you make the measurements in the manual someone on the reflector should be able to help you out.

David,
Don Brown has already given you some good leads - here are my additions: What you are saying is that your K2 has little or no power output - a reading of 0.1 or 0.2 watts really means no power output because that is the lowest indication that the microprocessor is programmed to indicate. You can do the checks in the 'troubleshooting section' by trying the things listed, but I suggest that you page forward to the 'Transmit Signal Tracing' section beyond that chart and use the RF Probe (the parts are provided with the K2 kit, so if you have not built it yet, now is a good time). If you have no power output, the RF voltage readings that you measure when following the steps in transmit signal tracing will be *higher* than the 'expected' value - *until* you get to the stage that is failing. Once you come to the point where the RF voltage is substantially lower than the expected value, stop, for you have identified the failing stage and troubleshooting that one stage for the problem is easier than guessing about the entire transmit chain. If instead, you want to just 'shotgun it', then you should check all components in the transmit section for proper values, good soldering, and good tinning of all the toroid leads. While it is possible that one of the transistors is not working right, I must point out that is a rare thing - most problems are first soldering, followed closely by improperly prepared toroid leads. Sorry I could not respond sooner, but I have other irons in the fire here too. 73, Don W3FPR [hidden email] wrote: > I am at the 40-meter transmitter alignment stage in Alignment and > Test, Part III. > > It instructs me to "Place the K2 into tune mode and activate the > built-in wattmeter by holding "TUNE".
