1. General Description
The MX800 series employs state of the art design and construction methods
to deliver a range of high performance, ultra reliable radio transceivers. They
are ideally suited for use in VHF or UHF two way voice radio systems,
however, the MX800 can perform in a range of applications where the added
advantage of linear frequency and phase response from DC to 3.4 kHz can be
utilised. The MX800 uses a two-point modulation method synthesiser for
extended low end VF transmit frequency response. The Receiver, Exciter and
Power Amplifier are contained in their own specialised aluminium module
and can be easily removed from the main chassis.
The flexibility of the MX800 series allows it to be configured for a wide
range of applications.
Standard MX800 applications include:
Conventional 2-Way voice base station
Full duplex or simplex base station
Radio modem base station
Direct FSK or SELCALL baseband repeater
Trunking base station for MPT1327, LTR, SmartTrunk and others
Analog Cellular base station
POCSAG paging transmitter to 2400 BPS
POCSAG repeater
DC-coupled Direct FSK modulation system
Voice repeater
Wide band data repeater
DC-coupled repeater
Point to point link
Fast 25mS repeater for multi hopping
Cross band link or repeater
Simulcast transmitter
Quasi-Sync offset transmitter
