VUCC is the VHF/UHF Century Club Award offered by the ARRL.

The "VUCC" program creates a map of worked VUCC grid locators from the VUCC Band Listing created by DX4WIN. The program shows checked (submitted), confirmed and worked locators, either in different colors or different fonts. Click this link to see an example of the output. See the color key below for the meaning of each color.

VUCC to HTML

Version 3.3 of the VUCC program was released on 24 June 2020. It is designed for Windows Vista and later, but may run on Windows XP. Go to the Version History to download the installation program.

Installation

IMPORTANT: If you try to run the program and you see either of these two (or similar) error messages pop up:

MSVCP140.dll is missing

or

VCRUNTIME140.dll is missing

then you must install the Microsoft Visual C++ Redistributable for Visual Studio. Download and install vc_redist.x86.exe (not vc_redist.x64.exe).


Creating the VUCC Data

The program requires a VUCC listing from DX4WIN as input. To generate this VUCC listing:

Using DX4WIN 8 and later:

Using DX4WIN 7 and earlier:

When the listing window comes up, right-click with the mouse and choose "Write to File". Give the file a name (no spaces). It will be saved as a CSV (comma-delimited) file. Take note of where this file is, because you will have to navigate to it from the program.


Using the Program

The program has a number of settings. The Input file, Band and Lower-left Field are required. The remaining settings can be changed to suit your needs. All settings except for Input file name will be saved and restored the next time you run the program.

After starting the program from the desktop icon, click on the Input button and navigate to the folder where you saved the VUCC listing from DX4WIN. Double-click on that filename to close the dialog box.

Select the band of interest by clicking on the down-arrow next to Band. Then type in the LL Field to specify the lower left-hand corner of the map. For USA stations "CL" will give you all of the USA and some of Mexico when printed in landscape mode. "CM" will give you most of the USA and some of Canada when printed in landscape mode. The field can be chosen to show any part of the world. You can type in a complete grid square (i.e. DM79nx), but only the first two letters will be used.

Next, choose the Print Format. There are three options:

Because each grid square is 2° x 1°, landscape output generally works better than portrait. Try 17"x11" only if you have access to a printer which can handle that size.

This is the color key for the output:

Note that in non-color mode, confirmed, submitted and checked VUCC credits will all be the same color (bold black).

Finally, click on the Generate button to create the output. Then click on the View button to see it. Windows will open the output using your default web browser. At this point, you can click the Done button to exit the VUCC program. Your web browser will remain open.

NOTE: Hovering the mouse over any setting should pop up a short description.

Clicking the Help button will being up this web page.


Tips on Choosing Colors

After clicking the View button, and/or printing, you may not be happy with the output. While the colors themselves can not be changed (yet), you may want to experiment with different settings of the various check boxes, as well as the layout. You can keep the program running. Simply make changes, then click on Generate again. You don't need to click on View, you can simply go back to your web browser and click on its Refresh button to show you the latest output.

I realize that I am probably violating the Americans with Disabilities Act due to lack of support for red/green color blindness. If that is the case, let me know and we can try to work something out.


Printing

To print using Mozilla Firefox:

To print using Internet Explorer (example is for IE7):


Known Problems:

The map won't wrap properly at the International Date Line. I probably won't fix this.
