Frequency deviation
Table of measured (at room temperature) values for carrier frequency deviation.
Positive numbers have no sign prefix. Negative numbers have 'minus' sign prefix.
Deviation in:
range is considered to be safe and typically needs no correction to be applied ;
range may affect operation of P3I (PilotAware) radio protocol ;
mark indicates that frequency correction is recommended.
