In addition, during reception, each channel supports only a single modulation at a time,

which can be one of the two listed below:

1.

Any of the PSK modulations (specified by the mode field in PSK physical frame,

Section 9.1.2

)

2.

FSK modulation, using the current FSK settings.

Table 12

shows the allowed combinations for single channel and dual channel reception

mode. Note that in case of FSK modulation on one channel and PSK on the other, the

maximum FSK symbol rate is limited to 2400 baud.
