Station Information Window

The Station Information Window centralizes all the information sources about a particular callsign. First, it will perform a lookup on various databases on CD or your hard drive. At present, the RAC Callbook CD and the free K4HAV FCC/VE Database are supported. Quick buttons will search for information on the QRZ and HamCall web sites or Google for other sources. Notes may be taken which will be displayed any time the callsign is entered.

The address or the latitude/longitude can be used to find the station location using Google Maps or the Google Earth application via the Tools Menu.

Press F11 to open the Station Information Window from other windows. If a callsign is selected, it will be automatically shown in the edit box. Station Information is also available on many of the right-click popup menus throughout the program.

If the window is opened with a callsign present, DX Monitor will search the Callbook and/or the K4HAV Database for a match and display the information in the Callbook window. If available, the name, address, Latitude and Longitude and US County will be shown.

The status bar at the bottom will show the beam heading, distance and sunrise and sunset times.

Google Map Button

Show the Google Maps page for the displayed address. Google Maps tends to show the address within a few houses of the actual house location on the street. Look carefully at the satellite images and you might spot the shadow of a tower or a big yagi. A lot of antennas are visible from space.

If you have the RACC Callbook installed, the addresses of foreign amateurs can also be mapped. If the address is not found, delete some words or numbers in the Google Maps search box until a map is displayed. The availability will depend on the location. Every day more maps become available. In some locations the satellite images are better than the maps.

HamCall Button

Search the HamCall web site for information about this station.

This is an edit window. You can use the normal editing keys (ctl-c, ctl-x, ctl-v, ctl-z) to edit the address shown and cut and paste it to another program.

Double click on URLs to show web pages. Double click on email addresses to automatically run your email program.


A free form area for typing or pasting notes about a station. Notes are saved in the folder Info in the DX Monitor folder. Each note is in the form of callsign.txt. VE3EJ's notes can be found in c:\Program Files\DX Monitor\Info\VE3EJ.txt.

When a callsign is entered, or the window is shown with a callsign present, any notes will be displayed. Changes are saved automatically. Normal text editing keys work (ctl-c, ctl-x, ctl-v, ctl-z, ctl-a).

The info folder should be backed up if you want to preserve the data in these notes. If you are installing DX Monitor on another computer, you may want to transfer the information in these files to the new installation.

Build FCC Database. Before using the K4HAV FCC and VE Database, it is necessary to install it in DX Monitor. The data will occupy approximately 30 Megabytes of disk space after installation. More space is required during the installation process.

DX Monitor's interface to the database was not built for memory efficiency. I would not expect good performance (if it works at all) on computers with limited memory capacity.

Installation Steps

  1. Go to the K4HAV web site. Scroll most of the way down the page and download the two files necessary for installation: (labelled as one big zip file and, in the next section,, labelled FCC Search Program Supporting Files. You may download the 14 smaller files that make up the big zip file if you are on a slow connection. You do not need any of the other index or support files for use with DX Monitor.

  2. Unzip the files to any temporary folder. Remember where they are.

    FCC Files

  3. Select Build FCC Database from the Options menu in the Station Information Window or use the button on the Call Databases tab in the Preferences Window.

  4. Locate FCC Support Files: ZIP0. A file open dialog will ask you to find the file ZIP0, which is one of the files in Find it and press Open.

  5. Locate FCC Data Files: ADDR_A.TXT. If the database files are not in the same folder with the support files, you will be asked to locate them. These are the 14 files downloaded as or as 14 separate smaller downloads.

    If all goes well, the status bar will show each of the files being loaded and the database being sorted. This may take from 5 seconds on a fast computer to a long time on a slow one with limited memory. Beta testers, I would like some feedback on this.

    FCC Database Contains 793207 records. If you see a message like this, the installation was successful. The exact number of records will vary. K4HAV updates the database once a week from the FCC central database. The downloaded files are no longer necessary for DX Monitor. All the information needed has been copied to the FCC folder under DX Monitor.

Show HamCall Internet Data. If this option is checked, the HamCall Internet Callsign Server will used to add more information for any searches. To use this feature, you must enter the password supplied with your HamCall CD ROM in the Call Databases section of the Preferences Window.

HamCall data often includes a web page and email address. Double clicking on a URL or email address will show the web page or open your email program automatically.

Tools Menu

Locate on DX Monitor Map. This is identical to pressing the Map button. The station location is shown on the DX Monitor maps.

Locate on Google Maps. This is similar to pressing the Google Map button. The station location is sent to and the map and satellite image are displayed on your web browser. You are given the opportunity to edit the address before it is sent. This is often necessary if the address is formatted in an unusual way or contains characters which might prevent a clean search.

Google Earth by Latitude and Longitude. The latitude and longitude as determined by the postal address of the station, or the prefix lookup of stations not listed in the FCC Database or Callbook are sent to the Google Earth application for display. You must have the Google Earth application installed on your system for this to work. Google Earth is free.

In the past, general location information was sufficient to allow accurate pointing of antennas and for casual browsing of large scale maps. With Google Earth, it is interesting to be able to zoom in on the exact location of the station, which is often different from the mailing address in the FCC or other databases. If there is interest in building a database of exact station locations, I can add a feature to help collect the information and make it available to all DX Monitor users.

Google Earth by Address. The address shown in the Station Information edit box is sent to the Google Earth application. If Google Earth recognizes the address, the view of the location can be extremely accurate. Try W3LPL, for example. Sometimes the address will only take you to a nearby street. The view is based on the latitude and longitude information, which is not as accurate as the address. In some cases the locator will be off the visible screen and it will be necessary to zoom out a little to see the location.

If the location is not recognized by Google Earth, the general area will be shown but the locator will be far offscreen. In that case, use the Latitude Longitude search to locate the station based on the zip or postal code information.

Check Propagation with HamCap. This is identical to the HamCap button.

Google Callsign. This is identical to the Google button. The callsign is sent to Google and the results are displayed on your web browser.

Update LOTW List

The ARRL Logbook of the World can be used to electronically QSL contacts for awards purposes. HB9BZA is maintaining a list of stations uploading their logs to the Logbook of the World. DX Monitor can read the HB9BZA list of all known LOTW users and use it to display LOTW in the status bar of the Station Information Window and in the status bar of the Main Window.

To update DX Monitor's list of LOTW users, click on the Update LOTW List command. The status of the update will be shown at the bottom of this window. In future, this process will be automated.
