(1) Special Controls Menu

When the antennas from more than one radio are placed within close proximity, the units must be

synchronised so that they do not block the transmission of each other. Although the radios are individually

configured to work within separate networks (with different hopping patterns, network addresses), they

must transmit and receive information at the same time to prevent signal blocking. One modem must be

configured as the sync output controller and the rest as sync output followers (note that a Slave unit cannot

be set as a follower because it has to synchronise with the master on the network). This will synchronise

transmission, however the frame size/length must be the same to enable synchronisation to work.
