About internal spurious signals
Certain frequency combinations of signals received simultaneously, may cause some effect on the receiver
mixer and IF circuits due to the high frequency of the internal oscillator.
However, this is not a malfunction (refer to the calculation formulas below: n is any integer).
Depending on the combination of the frequencies received at the same time, there may also be fluctuations
in the receiver sensitivity
z
Reception frequency = 12.288 MHz x n times
z
Reception frequency = 15.6 MHz x n times
z
Reception frequency = 2.4576 MHz x n times
z
Reception frequency = 6.1444 MHz x n times
z
Reception frequency = 11.1 MHz x n times
z
Reception frequency = 18.432 MHz x n times
z
Upper (Band A) frequency = (Lower (Band B) frequency ± 44.85 MHz) × n times
z
Lower (Band B) frequency = (Upper (Band A) frequency ± 47.25 MHz) × n times @ Upper band
(Band A) MODE = NFM
