Sensitivity
To optimize your radio for operation in different signal or noise environments, select a
sensitivity level from the list (the PDL radios used the term Digisquelch):
In general, have the Sensitivity level of the radio low enough to reject noise, but high
enough to accept signal. Signal is defined here as the radio energy you want to receive;
noise is defined as everything else. Suitable sensitivity levels to select depending on both
the noise level and the signal level are:
Signal
Strong Weak
Noise
Loud Low Medium
Quiet Medium High
Signal levels decrease with distance between the transmitter and the receiver. To extend
the range, set Sensitivity to Medium or High, although this can increase the amount of
noise passed through the radio. At times, it may not be easy to determine the noise level
without using a scanner or other RF energy monitor. If you are not sure about the noise
level in your work environment, you can use the following guidelines to set Sensitivity:
GNSS Surveying and similar applications Set Sensitivity to
GNSS base station radio Low
GNSS rover radio High
Environmental Monitoring and Similar Applications
Remote sensor radio Low
Local office radio High
Environmental noise levels may change throughout a work day and you may need to
adjust the Sensitivity setting. Most ADL radios include a user interface that enables you to
adjust the Sensitivity in the field without running the ADLCONF software.
