Chinese Checkers de K7QO

Yet another project in progress in the lab. This one to check both the quality of test equipment and parts from China. Thus the name Chinese Checkers.

    The K7QO Kit Building Slides for Pacificon 2016

  • K7QO Kit Building Slides for Pacificon 2016

  • K7QO's Kit Building Presentation at TBARC Presentation that I did for radio club. Should be close to matching the slides for Pacificon, but some mods were made.

  • Banggood Power Supply for Lab Work Make sure you select the US power plug, if you live in the USofA. I love this P/S as it has no RFI that I can detect at any frequency.

  • Alpha Metals Solder 1lb spool

  • QRPGuys 12W Dummy Load for $10 A good start for beginners and something that you can use later.

  • K7QO Build of a SWL-40+ from PCB. New PCB made from Gerger file created by member of qrp-tech@yahoogroups.com.

  • K7QO Lab Notebook Experiment Notebook.

  • K7QO SPICE Tutorial Notebook [Ver 0.32] Started Aug 12, 2016 and work in progress. Last updated Sep 28, 2016.

    The 2016 30m Propagation Study and WAS

    As a friendly challenge, the following stations have agreed to start on Nov 1, 2016 and go for WAS on 30m with only 1W or less using a KitsAndParts.com 1W transceiver. We are all starting with a zero count on states and we will see how the band behaves with QRPp power levels and at the same time attempt to work all 50 US states. Not a contest.

    The purpose to study the propagation characteristics of 30m band starting with the winter months and see if all 50 states and some DX entities can be worked using QRPp and QRP levels.

    I did TMPS in 1995 and did a paper at the first FDIM at Dayton in 1996. Here is that paper.

  • K5FO 1995 Thirty Meter Propagation Study My old call was K5FO.

    Here is my map of states worked followed by the list and the confirmed column means a confirmation on QRZ.COM in the logbook. The first person to confirm via qrz.com, in case of dups on the band, gets the honor of the confirmation.

    The map is obtained from the site at the bottom of this page and colored using a free program called inkscape.

    I use a program called INKSCAPE to edit the following map of the USofA. The map is in scalar vector graphics format. After I bring up inkscape and just simply click on the new state and then change its color to red and save the file, I export the file to PNG graphics format for use on this web page. Inkscape has a way to modify the map to make the background transparent so that the yellow of the web page shows through. This makes the map much more pleasing to the human eye that having it in a white rectangle on the page. IMHO.

    K7QO Legacy Documents

    The following are documents and work done some time ago. Please realize that some of the URLs, companies and other information may be gone from the planet Earth. This is here for those that might have unbuilt kits or have one that is not working. Also building techniques requiring tools that may no longer be available from the original sources or manufacturers. Please don't ask me to find things. If you can find it using google, then it is most likely that I can not help either. Good luck..
