(b) in category ii, channel numbers 1 to 24 are available with channel centre frequency of 173.7 MHz + (channel bandwidth × channel number);

(c) in category iii, channel numbers 1 to 11 are available with channel centre frequency of 173.7 MHz + (channel bandwidth × channel number);

(d) in category v, for use with ultra low power active medical implants only;

(e) in category vi and vii, channel numbers 37 to 47 are available with channel centre frequency of 458.5 MHz + (channel bandwidth × channel number);

(f) in category viii and ix, channel numbers 19 to 23 are available with channel centre frequency of 458.5 MHz + (channel bandwidth × channel number);

(g) in categories ii, iii, vi and viii, these bands may also be used in an airborne application for the tracking of birds–
