GB7SS using DMR (Digital Mobile Radio) is a TDMA mode (Time Division Multiple Access) which means that it allows several users to share the same frequency channel by dividing that signal into different time slots. Each frequency has a slot 1 or slot 2 and each slot can be used by different users. From an amateur point of view, using digital technology means that a single analogue repeater channel of 12.5Khz bandwidth can now effectively be doubled in capacity by carrying a digital signal comprising two 6.25Khz channels. This is achieved by very fast switching (typically 30msec) between the 2 digital timeslots that the mode provides (TS-1 & TS-2). Each repeater is also allocated a digital signature known as a Colour Code (CC) which is similar in function to CTCSS on analogue repeaters.
