Comments

Channels are defined to be 5 MHz wide, reaching 2.5 MHz above and below their center frequency. Most channels used by BAM are 10 MHz wide, so +/- 5MHz of their center frequency. This means we only use odd channel numbers as 10 MHz channels overlap with even channels.

20 MHz channels extend +/- 10 MHz. This mean the partially or completely overlap with two channels above and below.
