The recorder application is used for signal recording to a file (in WAV/ASCII format). It also supports noise squelch based triggering. In the squelch mode the user can define the power threshold. When the average signal power exceeds the defined threshold, the recording is started and when the average signal power is below the threshold the recording is stopped. The signal is recorded to the same .WAV file. The locations and timestamps of the recordings are written to the text based log file. When the recorder status indicator is white, the recorder is stopped and the new recording starts from the beginning of the file. If the indicator is red, the recorder is currently recording the signal. If the recorder is paused, the indicator is green and when the ‘REC’ button is pressed again the recording continues from the current location. The recorder supports also timer based functionality allowing the user define the date, time and duration of the recording.

If the squelch is enabled, the recorder is using noise squelch. The threshold for the noise squelch is set manually. There is also a power indicator showing the current signal power.
