About Internal Spurious Signals - Yaesu FTM-400DR Operating Manual

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
