  • Page 23: Theory Of Operation

    4. THEORY OF OPERATION 4.1. INTRODUCTION The VHF and UHF radios comprise of two PCBs (RF and digital PCB). These boards are connected by an 18 pin female and male connector. The digital board which controls the radio and data receiving and sending is interfaced with external data equipment through the 15 pin d- sub female (DB-15) connector.
  • Page 24 adjusted (amplified) by IC416-B. The amplitude-adjusted signal goes to pin 2 of the DB-15 connector (CON401). Audio signals are inputted to the 300Hz High pass filter (IC408) to eliminate sub-audible voice products through IC409. The output of the HPF is switched by IC406-A and de-emphasized by resister R471 and C452.
  • Page 25 unmatched, the busy L.E.D. (Yellow) would be shown. CTCSS/DCS ENCODE CIRCUITS During TX encode, the tone squelch digital signal is produced as a 3-bit parallel word at Pins 33, 34, and 35 of the micro controller (IC401). The 3-bit digital signal is converted to an analog signal by resistors R481, 482 and 483.
  • Page 26 CHANNEL SELECTOR One of 16 channels may be selected using the Dip Switch (SW401) and serial commands. The hardware selector, SW401 encodes the channel number, selected into 4-bit binary code. The binary code plus one equals the channel number. The binary code is decoded by the CPU, which enables the appropriate RX or TX frequency and associated data to be selected from the EEPROM.

Its compensation is ±5 PPM or less from -30c to +60c. PLL IC DUAL MODULE PRESCALER Input frequency of 12.8 MHz to pin 1 of IC2 MB15A02 (or MB15E03SL) is divided into 6.25 kHz or 5 kHz by the reference counter and then supplied to the comparator.

    DC TO DC CONVERTER The DC to DC converter converts 5v to 14-16v to supply the necessary voltage for wide range frequency in the VCO. The radio adopts a two VCO system for RX and TX in order to maximize each performance. The TX and RX VCO generates RF carrier and local frequency and each VCO is switched by a TX/RX power source.

    4.6. ACC-515 (GPS INTERFACE CIRCUITS) The radio series outputs an industry standard NMEA GPS sentence on the DB-15 connector when the GPS option board is installed. The GPS module releases NMEA-0183 format data every 1sec. To prevent unnecessary data from the GPS engine, the GPS output is controlled by Pin 6 of J1 (GPS_OUT), and besides, power save mode can be executed by Pin 4 of J1 (PSAVE).

    7. ALIGNMENT PROCEDURE The UHF/VHF Transceivers have broadband tuning range, UHF (450-490 MHz) and VHF (148- 174 MHz) should require no special alignment, unless repairs are performed on the transceiver portion. Should repairs be necessary, use the "Test Equipment Diagram" and the “Alignment Points Diagram", in conjunction with the following procedures: Extender Board (ACC-516) is required in order to separate the Digital and RF PCB’s to allow access to the alignment points.
