K2 #6705 question...missing part.
 
|
Hi Gang
The trials and tribulations with #6705 keep coming....HI HI I have looked high and low....over and over....and I can find no RFC15. This is a subminiature 100uH choke that is tacked onto the bottom of the RF board. I have the Qty 4 of the regular 100uH chokes that I'm supposed to have....but no additional miniature 100uH. Now here's the question: I've looked at the schematic, and RFC15 feeds power to the Synthesizer (U4). Without power to that chip I am through with the assembly of #6705 til Elecraft can get me a RFC15 shipped out. So I used one of the regular 100uH chokes... keeping the lead lengths as short as humanly possible...and it actually fit rather well. Is this likely to have any ugly consequences? I will contact Elecraft about the shortage....and I'm sure they'll handle it with the efficiency we've come to love and respect....but I don't want to lose this weekends effort! Actually....IF the installation of the larger choke gives me no instability issues, is there a reason to bust up a sexy solder job on the larger one I cabbaged in?? Jeez...this is not NEAR the fun I remember on my previous two K2s!! I'm having serious regrets that I didn't go with a K3 instead....HI HI Hmmmm, wonder if they'd let me trade up :-)) 73.....de.....Fred N9TA I hope the old Elecraft MOJO is still active!! ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Fred,
Check the last part of item 15 in the Errata sheet - that explains that the choke for RFC15 may be the same as the other 100 uH chokes. You *did* transfer all the information in the errata sheet into the manual before you started did you not? If not, that is standard operating practice and very important. I cannot emphasize the importance of the errata sheets enough - they contain the latest information and using that information can avoid many errors. In this case, it has only caused a bit of confusion. 73, Don W3FPR Fred Bennett N9TA wrote: > Hi Gang > > The trials and tribulations with #6705 keep coming....HI HI > I have looked high and low....over and over....and I can find > no RFC15.

My k3 started to act up tonight. It was not putting out any power in CW, and
was behaving as if it was in QSK mode even though it was in semi-breaking mode. The power output was OK in SSB. I tried to reload the FW and now it is stuck in MCU LD mode and the background light on the display is not lit. How do I get it out of MCU LD?

Hi Don
Actually, I thought I HAD added the errata. I put a note that the COLOR of the choke might not be as listed....but if it mentioned the SIZE as changed I missed that!! In any case, the parts list a QTY of 4 large 100uH chokes...which I have. And then it lists the miniature 100uH choke which I do NOT have. So I would have thought I'd have found 5 (FIVE) large 100uH chokes if I'm supposed to use one of them for RFC15 ???? 73 de Fred N9TA _____________________________________________________ Don Wilhelm wrote: > Fred, > > Check the last part of item 15 in the Errata sheet - that explains > that the choke for RFC15 may be the same as the other 100 uH chokes. > You *did* transfer all the information in the errata sheet into the > manual before you started did you not?

Fred,
Yes, there should be 5 100 uH chokes, if you have only 4, send a note to [hidden email] and request an additional one. The part number is E690004. 73, Don W3FPR Fred Bennett N9TA wrote: > Hi Don > > Actually, I thought I HAD added the errata.

Further to my previous email, I have tried to force a FW download per the

Hi Jeff
FANTASTIC !! Sounds like you are havin' a ball!! I seriously considered the K3, but I liked the K2 well enough to build a third one. I have broke my back since I last put a K2 together...although I get along fine in everyday life, my hunching over the workbench building # 6705 has me sore and grumpy. If I'd have known, I'd have chose the K3. I am looking forward to the finished product. Elecraft has a GREAT product,no matter which you choose! I'll look for your call on the air when I get this beast operational. 73....de.....Fred N9TA __________________________________________________________________________ Jeff Wandling W7BRS wrote: > Hi Fred, > > I bought a kit form K3 first.

Unplug the radio for at least a minute then try again to load firmware
