New version of the website: Summer is coming

A release of the QO-100 Dx Club website was deployed, offering several new features for it’s members.

A separate blog post will describe the changes in terms of data quality and QSO check workflow.

Under the hood

As the number of QSOs grew we had to study some performance optimizations. While the use of caching mechanisms it’s an easy fix that can be applied in many instances, we choose to have real-time data presented in our member’s profile pages, and that forced us to tweak some systems. Rest assured all the changes are transparent to our members and only reflect as a reasonably short response time in most of our pages. If you feel that a particular part of the website is slow please reach out to us trough our contact form.


The “Results” menu has grew with two new pages: Grid Map and Statistics.

Grid Map

You can now check a map with all the grids that are mentioned in our member’s logs. Only the grids from “valid” QSOs are accounted (learn more about our data quality workflow).

This is a global view and it’s not real-time, being updated at most once a day.


This page shows some numbers about our member’s QSOs. There are currently three sections:

  • Mode Distribution¬† displays a table and a pie chart with the top 8 modes in our database, and a 9th place with “Others” for all the rest. This view shows an interesting fact about our members: SSB is by far the most used mode! It’s nice to hear your voice on the bird! Having said this, I really have to try to do a Hellschreiber QSO one of these days.
  • Month Distribution is a slightly more complex view of the QSOs by month: you can check in each column the relative amount of QSOs by month in a specific year (and in general in the last column) and see how the QSOs are spread through the year.
  • QSOs by Month shows in a line graph the evolution of QSOs by month, with actual numbers.

Again, this data is not real-time, and is updated at most once a day.


Two new pages were added to the user’s Profile section, and a third was updated. We believe the changes and new features to be of value for members, since they’re all related with QSO validation.

Having a decent amount of QSOs from a large number of operators afford us the possibility to gather some insights and infer some conclusions about data quality, and it’s consequence for us: QSO validation. Seeing the opportunity that was presented we decided to provide tools that allow members to better detect mistakes on their logs.


A new column was added to the table, with an icon informing you of the validity of your QSO: it’s either a green check mark or a red triangle.

This classification is done automatically with the insights we have gained (and continually refining) from our member’s logs, and it must not be understand as a “written in stone” classification. We all make mistakes, even computers make mistakes. It happens. If you believe we have a mistake, please let us know. More details about the classification process can be found elsewhere in our blog.

QSOs with Issues

If some of your QSOs have issues, you can check them in here. The page displays a table with the QSO information and the issues found: sometimes is just a typo, sometimes is a little more. The information compiled in this page may be useful to check your logbook, so please use it at will. As I use paper logging (and have terrible handwriting) I found this information quite useful to spot my mistakes.

The information in this page is presented in real time without delays. For this reason you might need to wait a few minutes after uploading your log, to give time to the system to check the DXCC entity status with ClubLog to get meaningful information. Ten minutes should be enough.

Grid Map

Similar to the global Grid Map that is available in the Results menu, in this page you can get a map of all the grids that you have in your log. In fact, the pages are almost exactly the same, but in this page you will have only the grids you have worked, with any of your call-signs.


Again, similar to the global Statistics that is available in the Results menu, in this page you can get some information about your QSOs.


Finally, we decided that a blog were we could post random pages with information could be useful.

There’s already the “News” section that presents news about the QO-100 satellite operators and expeditions, but there was a place missing for news about the club. You can expect to find release notes just like this one whenever we make significant changes or fix bugs.

I hope you find this update useful.  See you on the air!
