About internal spurious signals

Certain frequency combinations of signals received simultaneously, may have an effect such as internal
beats 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
simultaneously, there may also be fluctuations in the receiver sensitivity.
Reception frequency = 12.288 MHz x n times
Reception frequency = 2.4576 MHz x n times
Reception frequency = 11.1 MHz x n times
168
Reception frequency = 15.6 MHz x n times
Reception frequency = 6.1444 MHz x n times
Reception frequency = 18.432 MHz x n times
