Re: [Elecraft] Elecraft CW Net Announcement
Hi all - I'm working on K2 #4607. I'm to the point of Alignment and Test, Part II. A couple of problems have come up. 1) The K2 is failing the PLL range test with a range of 9.47kHz. L31 is currently 10uH. I've emailed elecraft regarding this. Grepping the archives indicate that replacing L31 with 12uH may solve this problem. What's the consensus on this? 2) I completed the remainder of the alignment for Part II. I'm able to receive signals on 40m. However, any change in frequency results in a chirp occuring about 1/10 of a second after any frequency change is made. This chirp occurs on all 40m frequencies, on all step increments and all filter settings. I suspect this is the PLL taking an excessive amount of time to lock up. Once locked, the receiver is very stable. All voltages on U4 are within a reasonable value. Any ideas? Is this related to 1)?

[Elecraft] VCO/PLL Alingment and Test Part II

Re: [Elecraft] Favor to ask...
Anyone out there with a Blue Max crimp kit? I've used small pieces of angle iron and some vicegrips to do this. The angle iron distributes the force on the connector during crimping so that it isn't damaged. Works great in a pinch (pardon the pun... :). ~Don ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: FW: [Elecraft] OT - Way off topic, but Dell is giving away machines
About the Desktop vs Server question, Dell does not support does not mean it won't work. It does mean there is no AGP slot, but a PCI graphics card is fine for everything except Gaming, DVD viewing and CAD. Heck, the onboard Video is probably fine for hi-res, non real-time applications. The SC420 does have two PCI Express slots, whatever those areg. AGP and PCI are going the way of ISA and are being replaced with PCI Express. The latter is a serial bus and comes in a variety of widths. For video you normally get a 16 or 32x PCI Express that has 16 or 32 high speed serial channels feeding the video card. It is at least an order of magnitude faster than AGP. Here's a good link: http://www.intel.com/technology/pciexpress/devnet/docs/WhatisPCIExpress.pdf ~Don ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Freebie CAD program
I need to produce a couple of quality schematics. Anyone know of a freebie CAD program to do this. gschem under Linux/FreeBSD works great. Not sure about windows. Here's a reference: http://www.geda.seul.org/tools/gschem/ Screen shots are available. ~Don ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It's all Tom's fault - was: Re: [Elecraft] CW Tuning Indicator - Window of Opportunity Still Open
Ok, so I just ordered two of N0SS's SMD kits but I didn't have a K2 to put it in. Well, I rectified that and ordered a K2 for Christmas :) Long overdue. Thanks for the nudge Tom! :) ~Don K7DKD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
