Figure 9-1 AOR – AR3000A Radio Receiver
The software interfaces to a AOR-AR3000A professional radio receiver. The features utilised by the
Spectrum Scanner are as follows:
• Frequency Range 100KHz – 2036MHz
• Listening Modes
o NFM Narrow Band FM
o WFM Wide Band FM
o AM Amplitude Modulation
o USB Upper Side Band
o LSB Lower Side Band
o CW Continuous Wave
• Signal Strength
• RS232 Serial Interface
Control can be switched from the receiver keypad to the serial port input via a rear panel switch.
This is important to note as the serial port connection will not respond if this switch is not set
appropriately.
The Java Communications API is used to interface to the receiver using the serial interface. The
Java CommAPI is a standard extension to the J2SE SDK. It provides support for RS232 (Serial) and
IEEE11284 (Parallel) interfaces.
9.5 Architecture
As shown in Figure 9-2, the communication to receiver and its command set are encapsulated
by the rfsv.recevier.AR3000A object. This AR3000A object is exclusively used by a
SpectrumScanner object which manages the scan. Scan events are propagated to registered
GUI and ScanData components using an Observer design pattern [ 43 ]. This enables dynamic
visualisation of the data as it is acquired. Alternative implementations of the SpectrumScanner
could be implemented to utilise the receiver in different ways. For example, a more intelligent
Scanner would be able to identify stronger signals and then rescan at a higher resolution (i.e.
smaller frequency increments).
