DxDozer is an advanced DX Logging Application. It is suitable for begginers and for experienced Dxers. The name means that removes any obstacles that may prevent you for 'doing' that DX like a BullDozer.

System Requirements.

Needs Windows 10. It will work also under Windows 7 but not under XP. Needs Internet connection at least for the first time setup.


Download the Program from You will download the file ''. Unzip and run (double-click) the DxDozer.msi file to start the installation. The Installer will ask your permition to continue because will save the program to Program Files. Follow the Installation wizzard steps and you are Ready. You will have a Desktop shortcut and a shortcut in your Start Screen. The Program will be installed in 'Program Files (x86)/DxDozer' Folder.

First Run Wizzard

After the Installation starts the Setup Wizzard. It has 8 steps.

  • First asks you to create a WEB Account to To use the Program you MUST HAVE a Account.
  • The next wizzard asks you to select the Database type you wish to use. Click the [Default] if you are not sure what the rest entries are. If you have SQL Server you may wish to use it, or if you are going to run as a group of operators then Select an SQL server. Even the defaukt Database which is MDB file allows up to 5 concurrent connections.
  • Next Step is the Logbook Header Setup, You set your Callsign and your coordinates. Coordinates are important for various callculations.
  • Next step is the definition of 10 user fields. Those 10 fields are Logical fields and the values can be either truo or false (yes or No). For instance you decide to name the second field '3 Element Beam' if you log a QSO using that Beam you can set this field to true bu checking it. You can name them later from 'Logbook Properties'.
  • Next step is the LOTW credentials ,if you are a registered LOTW user. (You should be!). Check the image for the Station Location field which is mandatory.

DxDozer UI Layout

UI Layout

The program has two different modes of operation. "Easy Mode" and "Expert Mode". In easy mode there are available only most used operations and the Ribbon bar has only the necessary buttons.

Expert Mode

DxDozer Expert  Mode Ribbon

The Ribbon although looks like the one in easy mode actually has a lot of tabs with dedicated operations. The ribbon different tabs are HHome,Logbook,DxCluster, Telnet/Packet, Maps, WEB, Tranceiver Control,Calendar,Awards
Be aware that Many Buttons are disabled until you are in the proper view.For instance if you check the dxClsuter ribbon tab you will see the 'Ask DX' button grayed out, unless you select as telnet view. Because the command will be send to thhe selected dxcluster telnet connection. You may be connected to multiple dxclusters.

Maintenance and Backup



It lets you select the font and font size to use on every telnet View. You can change the Font Size from inside the telnet view using the Ribbon Home Menu buttons DxDozer font Increae/decrease

Packet Engine

Packet Engine is used only to get DXCluster Spots and transmit to Packet ,DxCluster spots received from telnet. Here you configure how to use Packet Engine. If Packet Engine Runs in the same computer then leave it as is the default settings are ok. Just enter your CallSign. The color of the header of received Packets can be changed and also the size of the Fonts.


The Maps options has two different (same) settings for Flat earth map and Great Circle map. On the map view you can see the DxClsuter received DXSpots. More on the description of the Map View. You can set the colors and font of the text for the DX Calls label on the map. DxDozer displays the DxSpots and draws propagation Lines from the Author of the dxSpot to the DxStation. You can use different line colors to distinguise the bands of operation. In General default settings are OK.

Transmission of Dx Spots

If in your area are HAMs that want to receive DxClsuter Spots via Packet, after all DxClsuter over Telnet is not so HAM(!!!), you can transmit the dxspots you receive from telnet to PAcket Network using Packet Engine. You can specify here the Callsign to use over the air and if needed any digipeater.

Dx Announcement

Here you define the way you wish to be notified of new incoming dxClsuter spots. If you choose 'Voice Announcements' you will hear from your PC the DXCall either as letters or using Phonetics like 'Siera','Victor' etc Visual announcement will display a small windows or your right lower corner of the main display with the DXCall for a few seconds. If you choose 'flash TaskBar' will flash the program tab in the taskbar 3 times.

Station Settings

Define your Call locator and coordinates, select also the units type. Preferred Startup Mode is the mode that the QSO panel will be filled when you dont have a tranceiver attached.If you are a CW fun the set CW.


Band Edges are used in the DxClsuter view(s) to sign the dxspot mode. DxSpots do not contain mode info, so the mode is extracted from the frequency of operation. If, for instance, the frequency is 14001Khz then defenetily is CW. You can define the band edges.In most cases the edges are fine annd in future versions you will be able to download updated band edges from You define here also the CW edges and the start/end of digital modes. In the Digital Modes subview you can set the frequencies used for digital modes. FFor instance if the DxSpot frequency is 7074Khz then is FT8.

Tranceiver Control

Here you define the tranceivers to control from DxDozer. For a new TRX press the [New Trx] button. Select then from the List the Tranceiver's model. Double click each column to select the Serial/Usb port the tranceiver is connected ,baudrate annd stop bits. If your tranceiver is not in the list use a Generic Brand model or Ask me to write the interface file for your tranceiver, from the support page.
To Remove/Delete a tranceiver entry select the tranceiver and press the [Delete] button.
If you have more than a Tranceiver connected then Press the [Bands] button to define which bands each tranceiver uses. Lets say that you have an HF tranceiver for low bands 160m,80m and 40m , another for the rest HF bands and another tranceiver for 2m and 70cm Band. If you see a DxSpot for 80m and double click on it in DxClsuter view, you can define here to jump to that frequency the first trnaceiver. If the DxSpot is for 15m band then will set the frequency to the second tranceiver and if it is for 2m then the third tranceiver.
