Introduction This operator manual serves as the primary document for familiarising users with the parameters of the radio modem MX160, its properties, modifications and with the parameters of connecting parts.
1. Radio modem MX160 MX160 is conceptually new radio modems designed for transmitting data in the VHF and UHF bands. The radio modem uses 2-state GMSK modulation providing for a maximum signalling rate of 133 kbit/s.
2. Description of Radiomodem MX160 2.1. Radio part The architecture of MX160 radio modems resolves most of the requirements placed on a top quality user friendly radio modem with a very short switching time between receiving and transmitting. Frequency synthesis enables operation on any random channel from a given frequency band.
Important CAUTION! Danger of explosion upon replacing the incorrect type of battery . Follow the manufacturers instructions for handling used batteries.
3. Connectors 3.1. Antenna The radio modem is fitted with two SMA type connectors for connecting an antenna. The connector labelled Rx is for the receiver , and Tx for the transmitter (up to 25 W). Use the corresponding type of connector with matched impedance as the mate.

Note For configuration of the menu using program Setr see „MORSE firmware documentation 1 “ A supply voltage can be applied to the board via the MR400 supply connector . In this case simply connect a wire with a positive voltage. When supplying from an external power source both leads need to be connected.

The T-port module can be positioned in the first or second optional module slot, see section Section 3.1 1, “View of Radio Modem”. (Or only in the first slot for MG100 modems.) The second slot is recommended because when using slot 1 you need to take into consideration the fact that it needs disconnecting when the modem is in service mode.
