To help you practice your CW for Field Day you can use real data from our club’s log, W0WTN with shuffled lines for the different speeds.
Since the files were created from actual log data they contain the actual exchanges provided by the stations. There’s no guarantee they will stay the same from year to year but a surprising number of contacts I have checked seem to operate the same number of stations from year to year.
Here is a Zip containing all log text and MP3 files (19Mb) 10 through 45WPM:
W0WTN LARK 2022 Field Day Log Data Text and MP3 Files.
Here are the individual files you can view and listen to:
Here are excruciatingly detailed instructions of the process I used if you want to create your own practice audio file. I did this so *I* can do it again when needed. You could use your own log data (requires Excel or Google Sheets to open and edit .csv files). Again, I mainly documented these steps for my own use. There are likely easier ways of accomplishing the same thing:
1. Open your log data in ADIFMaster
2. Export the file to the .csv (comma separates values)
3. Delete all columns except Call, Class and ARRL Section
This next step is optional but helps with the higher speeds to provide a more normal receiving rhythm by padding the time after each set of characters to more closely match actual FD exchanges (inserts one space after the call, another after the exchange and two spaces after the section):
4. Insert a blank column after Column A (between the “Call” Column and the “Exchange” Column). Type a space into the top cell. Press Ctrl-Enter to fill all the cells below with one space. Insert another blank column to become Column D. Type a space into the top cell of Column D. Press Ctrl-Enter to fill all the cells below with one space (between the “Exchange” and “ARRL Section” Columns). Select Column F which should currently be empty. Type two spaces into the top cell. Press Ctrl-Enter to fill all the cells below with two spaces.
5. Delete row 1 that contains the header data, “Call”, “Class”, and “ARRL Section”.
6. Export the file as a text file, .txt, tab delimited.
7. Open the text file in Notepad or similar text editor
8. Select all the text (Ctrl-A), then Copy (Ctrl-C).
Optional step: Use a Line Shuffler to randomize the exchanges (I did this so the audio files wouldn’t all start with the same contact data)
9. Go to Learn CW Online
10. Paste the contents of the text file into the text box. (Note: you can also upload your file but the file size is limited to only 8000 characters). Although the spaces may not show up in the converted code they will be present in the actual resulting audio file.
11. Select your desired Character Speed, Effective Speed and Tone
12. Click “Convert”
13 Download the MP3 file and save it to the location of your choice.
