CTR2 provides basic logging functions. The buttons across the third row allow you to enter log data during a QSO.

The Auto>button is a feature unique to CTR2. It opens the Select Items to Log page. This page lists any entry in the Rx buffer (last 500 characters from the decoder) that looks like a call sign or RST report. To add a call sign or RST report simply touch the call and RST sent and/or received buttons then click <– to return to the Home page. Touch Cancel to return without selecting any items.

Terminal Session on Tera Term

The menu provides directions for using the terminal.

Press Tab to list the log file. Once the log has been listed copy and paste the text of the file to text file with a .ADI extension.

There are instructions for using the terminal as a keyboard for CW and RTTY. This eliminates the need for a separate USB keyboard or mouse to control CTR2’s keyers, however third-party app can’t control the HMI once the terminal connects.

Once you have imported the downloaded file into your logging program you can delete it from CTR2’s SD card by clicking Delete Log button in the Config page.
