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.
