Heterodyne system and time expansion (selectable x10 or x20)

Backlit display, large numbers, accurate digital display, showing the tuned frequency in the heterodyne mode.

Frequency and volume controls are on the side of the case, making adjustment easier. Using a stereo headset, the heterodyne signal is heard on the left channel and the time expansion signal on the right channel. When the built-in speaker is used, a switch is used to select the heterodyne or time expansion signal.

A digital recorder can be connected to the D240X to record extended calls for analysis on a PC. If the recorder has a voice-activated recording mode, a fully automatic bat recording system is obtained, which can be left on the ground for unattended recording of bat calls .
