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. It will create also a Folder in 'Documents/DxDOzer' where will store your QSOs Database and other usefull files.

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.
  • Next step is to create the Logbook Tables in the Database using the data you entered so far.
  • After that the next step will updatre the DXCC entries/Countries. The operation needs Internet connection.
  • The Wizzard continues with LOTW and OQRS users update
  • Finally you can import your QSOs from your outdated Logbook program if you have an ADIF file. You can bypass it and do it later.
    It is important to import your QSOs if you wish to have correct DxCluster marking.
  • Now you are ready for your first program run.

First Run

The program runs and you see on top the Ribbon, below the tan strip and the Views, Below the viwes is open the 'QSO Log' Panel and below it the Status bar. On the left are 3 other panes 'Map Legend','Parrot' and 'CW'.
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

Backup Depends on the Database you selected to use. If you selected the default MS Access Database then you need just to copy the database file AGWLOG.mdb to another disk or stick to backup your data or to trnafer them to another computer.
If you selected SQL server then you know how to backup.
Maintenance is neede if you imported your QSOs fron another Logbook and you find that some entrie have wrong band or mode. DxDozer will try to fix mode and Band from the QSO frequency. It will try also to analyze the Callsign and find the right DXCC Country.



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.


You can define, if you want, to protect your Logbook from unauthorized usage using a login/Password screen.
You can change the database Server in use by choosing a differnt server.You may wish to connnect to a databse server in another computer or on the Cloud.
Do not touch it unless you are very sure. BTW try to get regular backups of your database to another computrer or on the Cloud or on usb Sticks.

You can use a webservice to find Operators info like Name,address etc for if you have a subscription or from for free. Just enter the login/Password for the web service. Perhaps is a good idea to create an entry for your call the free WebService

Logbook Properties.

You can change your Logbook properties at any time from File Menu. The dialog has 4 Tabs (Panels).


Callsing The callsign you use to log QSOs.
Owner To Whom the Logbook belongs. e.g if you have a special call then Enter the special call to Callsign field and your call to this field.
Description Describe the Logbook. E.g Main Logbook or special evvent station to celebrate etc etc
Locator and Coordinates The place where you operate. If you Know the locator and not the Coordinates enter locator and press the calculate Button to calculate coordinates and viceversa


It displays the QSOs logged so far and dates of the first and last QSO.

User Fields

The Logbook has space for 10 user fields. You can assign any name you wish to each field. For instance you can define the tranceivers you use for each QSO. You may wish to enter the power in use for each QSO. All these fields are Logical. The can accept Yes(TRUE) or No(FALSE).


You enter here your LOTW credentials. Password is saved in the database encrypted LOTW is used to upload QSOs ,receive QSOs confirmed etc.
There is an image where you can see what you need to enter to 'Station Location' fields.

Views and Panels

DxDozer has many different views and a few side panels.
Panels can be docked on any side of the main Window and can be either always open or automatically collapsed to not occupy space.You use the Pin on the top of the panel to manage visibility. To move a panel first press the pin and the drag the panel header and move it any where. You can left the Panel 'Floating' over any window.

QSO Panel

The most important Panel.By Default the panel is opend on the bottom of the main window. It has a toolbar and the fields necessary to enter a QSO. The necessary fieklds to Log a QSO are Callsign, Date and Time, Frequence and mode. All other fields are optional. Tip to Log QSO Enter the call of the Station and leave the cursor in the Callsign field while calling the Station. If there is a pileup tehn you may do the contact after a few minute or even more. When the DxStation answers yoiu then move the cirsor from Callsign field to any other field. Automatically the Time will be set to Current time. You can do it many times. Each time you move the Cursor from Callsign field to any other field the Time field is update with the current time.
For Contests if you enter a number isnide the 'Contest SND' field then every other QSO the number will be increased by one. To stop this just erase the field. Contest operation is not suitbale if you intend to run a Contest, but if you find dx stations during a contest and wish to work them. Later you can export this QSOs and send to Contest Authority to validate QSOs.
to Log the QSO and save it to database press the Save button on the QSO panel Toolbar.

QSO Panel ToolBar

If you rest the Cursor on top of each toolbar icon you will get the information tooltip. In breif you can clean the QSO fields, Save the QSO to database(Log),Spot the QSO details to DxCluster,See the DXCC status for this DXCC country and also previous QSOs qith the same station,Check the Station on QRZ and turn on or Off the tooltips.

Telnet View

Telnet View is used ,mainly, to connect to DxClusters. You can open and ocnnect to many different clusters simultaniously. In the DxClsuter view you will see the source of each spot.
The View is divided into two panels (upper and lower) the upper panel displays the received dat from the server and in the lower panel you can type and send the data to the server each time you press enter.

to Connect to DxClster right click inside the upper frame of the telnet view and select [Connect]. Enter the Address/port of the server and you may write or use the default macro file to automatically log you to the dxcluster. The default macro file and some other examples are in the documents/DxDozer directory to examine and edit them. If you press [Default Srv] then telnet will connect to default DxCluster. You can check available server by pressing the link at the bottom of the dialog.

DxCluster View

Probably the most important view and quite complex (hi,hi), The view designed to show you with just a glance what happens.

Left Side-General

You can select the band you wish to see. Just check the desired band. Check also the desired Mode, Authors and Dxstations. The most importand is the Type of Spots to see. Not Worked you will see spots with stations that you never worked before on any band any mode.
Worked Not Confirmed you will see spots with stations that you worked before but you havent QSL in any band any mode.
Not Worked/Confirmed Band you will see spots with stations that you hadnt worked or Confirmed in this Band.
Not Worked/Confirmed Mode you will see spots with stations that you hadnt worked or Confirmed in this mode any band.
Not Worked/Confirmed DigiMode you will see spots with stations that you hadnt worked or Confirmed in Digital mode any Band.

Left Side-Search

FT8 View (Integration)

Probably the most important view for FT8/4 Users. The view designed to show you with just a glance what happens while working on FT8.
You must configure properly the WSJT-X software. While the WSJT-X receives the received stations are displayed in this View and you can check which station you need to work, if they have LOTW or OQRS etc. From the left side tree you can select the type of stations to Display.
When you decide to worka station you just double-click it in this View and WSJT-X starts to call him.
You can run many copiew of WSJT-X with different Tranceivers. DxDozer sends the commands to the proper WSJT-X/tranceiver.
Last and Important is that When you finished a QSO then the QSO is automatically logged to DxDozer.

WSJT-X Setup

  • You must Enable UDP Server. Is the mid section in the settings.Enable it to receive stations from WSJT-X and be able to ask WSJT-X to start QSO with a Station from DxDozer FT8 View.
  • You must Enable 'Enable Logged conatct ADIF broadcast'. In the bottom section. That way QSOs you made will auto logged to DxDozer.
