WARNING WARNING WARNING
Certain power transistors used in this equipment and their associated heatsink components are
manufactured partly or wholly from a beryllium compound. Normally these can be handled
without risk of toxicity, but there is a toxic hazard if dust or finely-divided particles of the
material are inhaled or enter the body through a cut. Consequently, great care must be taken, and
hands must be washed after handling.
Any cuts or abrasions on the hands must be covered by dressings while such components are
being handled. If beryllium dust does enter the skin through a cut or abrasion, the affected part
must be washed thoroughly and treated by a doctor.
Components containing beryllium may only be machined, cut, abraded, or heated above 400 C
under strictly controlled conditions approved by the appropriate Safety Authority.
Disposal of Beryllium
Disposal of faulty components must be carried out according to special arrangements. Should a
component containing Beryllium be broken, its parts and particles must be gathered carefully
using a moistened tissue (preferably while wearing plastic or rubber gloves), placed in a plastic
bag together with any contaminated materials, sealed, labeled, and disposed of in a manner
approved of by the Safety Authority.
Beryllium Components in MCC-545C RF Power Components
RF power components in the modules listed below incorporate some Beryllium within the
transistor package and must be handled as specified in the above warning notice.

1.0 INTRODUCTION
The MCC-545B PACKET DATA RADIO is part of a Meteor Burst Communications System
(MBCS) that allows short and long range communications between any two Stations in the
system. The system offers continuous radio signal propagation via ground wave and meteor
burst. Ground wave covers short distances, up to 100 km (60 miles). Meteor burst covers longer
distances, up to 1,600 km (1,000 miles), reflecting signals off ionized electron trails created by
meteors entering the atmosphere at a height of about 100 km (60 miles) above the earth's surface.
These trails, called bursts, are random but predictable in number and last from a few
milliseconds to several seconds. During this time, information can be exchanged between two
Stations. The height of the trails (60 miles) gives the system its 1,000 mile range.

2.0 DESCRIPTION
2.1 General Description
The MCC-545C Packet Data Radio provides versatile communications from fixed or mobile
sites. The 545C can be used for sending and receiving messages, position reporting, data logging,
or other specific applications. Designed to operate over a fading groundwave and an intermittent
meteor burst communications channel, the unit's low standby-power consumption (<1 watt)
makes it ideal for remote locations or mobile operation.
The 545C features rugged construction in a weather-resistant enclosure that measures 10.6 " x
4.0" x 2.42" and weighs less than 3.5 pounds.
A photograph of the 545C is given in Figure 2.1.
The unit operates in a half-duplex mode and contains a solid state Tx/Rx switch that allows a
common antenna to be shared for both transmit and receive. It can be operated with a single
frequency or on two separate frequencies.
The unit utilizes three phase locked frequency synthesizers to set the Tx and Rx frequencies.
The operator can set the frequency to any authorized frequency (10KHz steps) within a 2 MHz
band. Authorized frequencies can only be set at the factory by trained technicians. A factory
technician is required to retune the transmitter and synthesizer if operation outside a 2 MHz band
is desired. The unit can be factory tuned across the full 37 to 50 MHz band
2.2 Send and Receive Messages
The 545C provides full text message capability. With a portable operating terminal, or a PC
running terminal emulation software, you can exchange messages with any other Remote Station
in the network.
Messages may be plain text or binary data. They can be routed to single or multiple destinations
or, to a Host Computer or Data Center.
2.3 Data Logging
The 545C can be programmed to acquire, store, and transmit data from the various I/O signals
noted below. Any analog or digital input can be used to trigger a transmission or to set a discrete
output level. Output levels can also be set hi or low via a command received from a distant unit.

FIGURE 2.1
Refer to Appendix E for detailed operation and control of the I/O capability of the MCC 545C.
The MCC can also be connected via an RS232 port to a variety of Data Loggers such as the
Campbell Scientific CR10X or CR23. Data from these loggers can be collected, stored, and
transmitted to a distant unit. Refer to Appendix B and E for a description of data logger
interface.
2.4 Position Location
The 545C delivers location data from either a built 12 channel GPS (optional) or from an
external GPS with NEMA 0183 format, positioning equipment used in mobile units on land, in
the air, and at sea. The 545C sends the position location to a Master or Base Station, which
forwards the information to a Data Center or Host Computer for processing. This data can be
used in dispatch centers, corporate/district offices, and other monitoring Stations for updating

map displays or additional functions. Refer to Appendix B for a description of the GPS
commands.
2.5 Maintenance Features
An operator terminal or a remote command from a distant unit can also be used to read and
display the 545C's status such as radio propagation channel statistics, battery voltage during
transmission (loaded), battery voltage when not transmitting (unloaded), RF forward and
reflected power (checks antenna), and receiver noise levels. It can also be used to display and
configure the 545C's operating characteristics, as detailed in Chapter 4.
An internal Li ion battery is used to maintain the internal real time clock and battery backed
RAM. This battery is capable of operating the clock in a power down state for a period of
approximately 6 months. This battery should be removed if the unit is stored without power for
extended periods of time.
2.6 Hardware Organization and Layout
The unit contains five printed circuit assemblies:
A 100 watt all solid-state 2 stage power amplifier.
A 2 watt 2 stage preamplifier and power switch.
A BPSK 4 KB/sec transceiver containing a BPSK receiver, vector phase modulator (+13Dbm
output) and three frequency synthesizers.
A low-power microprocessor controller used to perform radio control and link and network
protocol functions. This assembly also contains a digital signal processor (DSP)and
digital to analog converter (DAC)for generating the in-phase (I) and quadrature-phase
(Q) base band signals required to generate the BPSK RF signal.
An 8 channel GPSreceiver (optional)
The following paragraphs contain a brief description of each of the five main hardware elements
in the 545C. Figure 2.2 presents a block diagram for the 545C. Figure 2.3 presents an outline
