  4. Traffic help, search by dxcc. 

The logbook in the clouds ?
It simply means that you do not install anything in your PC.

Your logbook is always available on any PC / TABLET / Phone
in the WEB browser of your choice.

The main advantage is that it is saved every 24 hours.
The disadvantage is that there is no "yet" OFFLINE mode, so you need an INTERNET connection.

1. Creation of a log on the site :

Here we will create a log on the site, for that we must launch the logbook by clicking on "log":

Then click on "Create new log":

Then enter: the name of the log, leave the other options empty if you want, then click on the "Save" button:

1. Import an ADIF log from your PC to the site :

The import is done by clicking on "Import / Export QSO",
then on "QSO Import from File to my Database":


Then choose your log file in ADIF format (that you can generate from your current log software LOGGER32 / HRD for example),
then choose the name of the log you just created in the list, then click on "Save":

=> If the ADIF file does not pass, make a ZIP before and restart the UPLOAD.


Note that the system will import your log but also automatically generate the statistics for the DXCLUSTER (for all the help part of the DXCC),
Thanks to the check box: "Dxclcuster update DXCC statistics after log importing"

The following screen appears, click on "Yes":


The following screen indicates that your log is being imported, a chat message indicates when it is finished :


=> You can close this window (press ESC).

=> Here I put 1min20 for the import and 1min50 for the generation of the stats DXCLUSTER (with a log ADIF of 11Mo zipped, source data F6FLU).

3. Generation of DXCLUSTER statistics.

But then what are these DXCLUSTER statistics for?
In fact you may have seen each SPOT is displayed with a color code,
this code tells you if you already have contact the DXCC and if so in that condition:


Suffice to say that the red is very interesting, so you'll tell me, but it's hard to follow the spots to identify those in red,
that's why the help to the DXCC (called DXCC ALERT ) Is for you.

Displaying help for DXCC: 

This is displayed in the right pane of the site in the block called "DXCC Alert".
=> Here we will see that DXCCs not contacted on a data tape:
=> The refreshing is done every 10 seconds (nothing to do user side is done automatically).


There are statistics on the known DXCC (via the import of your log and the generation of statistics),
Here 326 countries. As you can see the system will search in the last 24 hours of data.

There are 3 columns, one with the date of appearance, one with the DX and finally one with a link to the DXCLUSTER database.

Clicking on the small icon in the DB column displays a window that will search the DXCLUSTER database.

Viewing contact statistics in the spot display:

We find the same color code and we can click on it to go to display the statistics, for that just click on the little square of color next to the CALL here if I click on the blue square I "HI3T":


I post here all the QSO that I could do with Dominican Republic and on which bands.
Attention it is an extract, to have more detail it will go through the logbook then go to the research part.

Note that you must press the ESC key to close this information window.

Update DXCC statistics from the LOGBOOK:

This is done in the LOGBOOK, click on the "DXCC Stats" button, then click on the "Syncronise dxcc with dxcluster display" button.

Then choose which log (s) you want to include in the generation of statistics,
finally click on "Launch syncronization":


The system will then calculate the DXCC statistics from the logs you have chosen and insert them into the database.
Once the import is finished you will receive a message "SYSTEM" via the CHAT of the site (in the form of a small popup).

Note that if you enter your QSOs online on the traffic book, you will need to do this from time to time,
it is not automatic, triggered by the entry of a new QSO (I plan to provide a system later for that).

Note also that the system will generate each time the set of statistics or logs that you choose.
This will erase the old statistics and write new ones in base (it does not affect your QSO).

4. Traffic help, search by dxcc :

An interesting feature here if you are looking for a particular country and want to know:
If you have contact (so presence in your online logs)
Or if he is currently in frequency.

In the traffic book, click on the "Entities DXCC" button at the very top.
Here I want all DXCC on the continent AFRICA:
=> To do this I click on the button FILTERS, I chose the continent, then SAVE.
=> The icon will change color (orange) indicating that the filter (s) are active.


From there I can choose a country that interests me and see if there are spots (via the cluster link in the cluster column),
or if I have already contacted him via the qso link in the qso column.

Here for example Ethiopia, if I click on cluster, I have this:


Note that if I click on the link "GroupByCall" at the top I can display either in grouping of all the indicatives of the spotters or then displays only one spot by gathering all the spotters (makes it possible to lighten the display thus).

This has one drawback is that we do not necessarily see who are the spotters of our country.
Here I click on the link to "ungroup":


Finally an interesting function to see what was the traffic with this country and switch to the archives.
For this click on the link "Switch to archives" (to return to normal mode click again on it).

=> Note that the loading can take up to 30 seconds because there are hundreds of thousands of spots in archives:
