Power Supplies
The following voltage leveis are necessary for major blocks of the BSRiGO:
- +125 Vb for the output power amplifier, the driver and antenna switch feeds.
+8V for the driver and predriver feeds
+5V for the digital block, modulator chip, and active audio filter supply‘
+8 V5 and rSVs for the synthesizer feed.
+8 Vr and +5 Vr for the RF, lF amplifiers, and MC 3372D chip feeds
To provide the noise junction between the electrical feed circuits of the
transceiver blocks, and so that the supply voltage is sufficiently clean and stable,
the Power Supply contains five LP2951 low~dropout micro power-voltage
regulators.
The following voltages come through switch transistors to the cascades oi
BSRIOO: +8V, +8 Vv (from the 8 Vv and 8V regulators), and +125 Vb (from VB
port).
Under the following conditions, BSR operations stops:
0 When there is an error in the output voltage from the regulators (bus error), an
error signal is sent to the micro-controller and operation stops.
0 When the battery output voltage is at a low Vb voltage level, the +8 Vv
voltage regulator sends a “dead battery” signal to the micro-controller and
operation stops
In Tx mode, the +8v voltage is sent through switch transistors to the driver and
predriver cascades of the transmitter The +VB voltage through switch transistors
is sent to the antenna switch The voltage +8Vv is sent through switch transistors
to VCO\'l‘x and to the buffer amplifiert
Micro-Controller
The micro-controller, A’l‘ 89C52, is the original member of the MCS@-51 family.
The main features of the AT 89C52 are:
S-bit CPU optimized for control applications.
Extensive Boolean processing (single—bit logic) capabilities.
64K program memory address space.
8K bytes of on—chip Data Memory
256 bytes of tin-chip Data RAM.
32 bi—directional and individually addressable l/O lines.
Two 16«bittirner/eounters, full duplex.
UART
6-source/5—vector interrupt structure with two priority leveis
On-chip clock oscillator
The micro-controlier operates with an external E2PROM. The GuplOTM external
computer program is used to change the receiver, transmitting frequency, time out
tuner, and PTT Delay.
The input serial data (from the laptop/PC) is sent to the micro-controller through
the external communication connector The micro—controller produces Clock,

Data, and Load Enable signals on pins: iii], and ll of the i'viBiSijl chip. it uses
the lock detection signal to determine phase comparator output. When level on its
port is low, the phase is locked. While the phase difierence of Ft and Fp exists,
the output level goes high.
The PTTI extemai signal is used to configure the Tx/‘Rx modes. If the PTTi level
is “0,“ Tx mode is active. When the Lock Detector bus is “0,” the micro-controller
through ~ 40 msec shows PTT2 I ”0,” and the transmitter is in TX mode.
Conversely, ifthe PTTl level is “l,” Rx mode is active. When the Lock Detector
bus is “0,” the micro»controller shows Pm ”I,” and the transmitter is in Rx
mode.
The micro-controller uses the Channel monitor signals for the channel busy
determination. it makes signals for the Led indications (see description of self-test
LEDs).
Software Description
F u n ction
The BSR Sottware allows BSRIOO to function as a two~way radio in the
following modes:
- Rx Mode: receives the RF signal and provides a low frequency Audio Out
signal for connection to the external Decoder.
o Tx Mode: triggered by an External PTT signal from the Encoder.
The PTT signal initiates the PLL Synthesizer programming. Data for the
frequency programming is saved in the EZPROM.
After the transmitter frequency is entered correctly into the Synthesizer and the
PLL is locked, the Synthesizer issues an LD signal. After the Micro detects that
the LD is active, it issues a signal PTTZ it then turns the antenna switch to Tx and
powers ON the pre-drivcr and driver of the BSRU to transmit the applied Audio
lN signal.
Programmable Parameters
BSR communicates with the General Utility Program (GUP) and the Automatic
Tester with the help of MICRO’s UART. UART has been preset in the install
module to: 9609 baud; ’on Parity; 8-bit data; i stop bit.
It is possible to program the following parameter values:
. Transmit frequency
0 Receive fi'equency
- Tx time out (Tx time out is the maximum permitted time of continuous
transmission. Afier this time, PTTZ is deactivated, regardless of external PTT
signals).
Troubleshooting and Symptoms
if any problems appear, the software detects the source and switches off the
corresponding block to prevent any damage.

For diagnostic and repair purposes, the BS'R has a diagnostic mode. The
diagnostic mode is disabled by default, but can be activated by tripping P27 of
the Micro to LOW. Diagnostic mode enables BSR blocks to be anaiyzed
separately, using special PC Software for technicians
