The Recorder function allows the user to store received (filtered) PGNs into an MS-Excel-compatible csv file.
The control buttons are self-explanatory, since they resemble those of any standard recording device. Click Record to start the recording process, and the program will display the number of current records as shown above.

The data format is .csv (comma-separated values), which can be viewed either per an ASCII text editor or Microsoft Excel.
