In two channels receive, the nRF24E1 receives on two, separate
frequency channels simultaneously. The frequency of receive channel 1
is set in the configuration word B[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
