“Please note, this transmission is not optimized for easy listening, but for scientific research. […] Additionally, animal voices may be very faint. Amplifier settings are a compromise between picking up distant animals and not overdriving the system by nearby calving icebergs. So you might need to pump up the volume - but beware of sudden extremely loud events.”
