It is used heavily in many parts of the world, except for the USA. By looking at the frequency info window you can find neighbour networks. Trunked systems use a control channel, called the trunk, which transmits data packets which allow a talkgroup to carry on a conversation by telling members of a talkgroup which frequency to communicate on when they key up. Okay. The word is made from the Greek prefix tetra- (four) and -skelion, from the Greek skelos (leg). A computer network is a set of computers sharing resources located on or provided by network nodes.The computers use common communication protocols over digital interconnections to communicate with each other. Both point-to-point and point-to-multipoint transfer can be used. DMR stands for Digital Mobile Radio and is an international standard that has been defined for two-way radios. The control channel frequency is the frequency shown in the top row of the Telive window in the green bar next to the word "Down:".
