XO_F:
In two channels receive, the nRF2401 receives on two, separate
frequency channels simultaneously. The frequency of receive channel
1 is set in the configuration word bit[7-1], receive channel 2 is always
8 channels (8 MHz) above receive channel 1.
Utilizing 250 kbps instead of 1Mbps will improve the receiver
sensitivity by 10 dB. 1Mbps requires 16MHz crystal.
