The HAL HFCS-1000
Environmental Communications Simulator (ECS) is a
microprocessor-driven training aid that simulates operation
of the RACAL R-2174 (P) URR Radio Receiver used by U.S.
Government agencies. The HFCS-1000 internally generates
Morse code (CW) and Teleprinter (FSK and DFSK RTTY) signals
over a simulated spectrum of 0.5 to 30.0 MHz (full tuning
range of the R-2174). More than 1,000,000 background signals
from ten geographical regions of the world are generated
(more than 100,000 per region). In addition, "target"
signals may be injected via a serial I/O computer
connection. Ionospheric propagation effects, noise sources,
and various interference effects may also be selected via
the serial I/O port.
The HFCS-1000 is designed to be used in a multi-station
training situation wherein many receiver simulators are
driven by an instructor's computer via a Local Area Network
(LAN). When time-coordinated through the computer network,
each HFCS-1000 in the classroom is synchronized so that each
student receives the target text at the same time and
frequency. This assures an accurate and fair assessment of
each student's performance. All adjustable panel control
positions are monitored and may be read by the instructor's
computer via the serial I/O port to provide information
about student operational errors during the training
session.
The HFCS-1000 is the same mechanical size as the R-2174
receiver and the front panel duplicates the appearance,
controls, and displays of the receiver. External connection
include AC power, RS232 serial I/O port, and three audio
outputs (headphone, speaker, and constant level line). The
HFCS-1000 is constructed in modular form to assure rapid and
simple repairs. The HFCS-1000 may be manufactured in either
commercial or TEMPEST (NACSIM 5100A) versions.
