CWWDSDTV100XX100W VHF MOBILE AMPLIFIER

User Manual: DSDTV100XX VHF Mobile Power Amplifier 1. General Information This is a 100W mobile VHF amplifier. It is intended for amplification of single carrier phase (frequency) modulated narrowband signals in the 136-174 MHz frequency range. The input power is divided into several ranges. Be sure to operate within the specified range. PIN diode switching is used to switch between transmit and receive. 2. Construction The unit is assembled in the chassis with heatsink, intended for convection cooling (see Fig 2). Unit dimensions are 2.8” x 6.8” x 9.8”. 2 3. Installation Install the unit in one of two positions, showed at the right side of Fig. 2: vertical or horizontal. The proper air access to the unit shall be provided: no obstacle for air is allowed closer than 3” from heatsink. Also, make sure that status LED can be monitored. Screws from # 10 to # 1/4-20 are recommended. See the fastening holes positions in Fig. 3. Use copper wires # 10 AWG shall be used for connecting to clamps “+ BATT” and “GND”. Use copper wire from # 16 AWG to # 12 may by used for connecting to clamp “+ IGNITION”. Wires shall be crimped for making ring terminals. Connect the clamp “GND” to the car nearest ground screw of suitable size. Connect the clamp “+ BATT” to the pole “+” of car battery. Use 30 A fuse for protection. Connect the clamp “+ IGNITION” to the output of car ignition key that is able to provide not less than 8 V and not less than 3 mA when it is keyed on. Use 0.5 A fuse for protection. Use 50 Ohm coax cables with THC (M) connectors for connecting to “XCVR” and “ANT” . Connect the port “XCVR” to RF output of radio. Connect the port “ANT” to antenna. 4. Operation - LED “DC” goes on continuously, when the car ignition key is ON position; - LED “TX” goes on continuously, when the RF input power is greater ~1/3 of minimum rated level (see Table 1); - The continuous transmit time should not exceed 2 min, and the duty cycle should not be greater than 25% to avoiding overheating; - In the case of overheating (the heatsink temperature reaches +85ºC) the unit switches to RX mode, and LED “DC” starts flashing (independently of input power); - If the load VSWR exceeds 2-3:1, the output power reduces, and LED “DC” starts flashing, when RF signal is applied to the input.' 3 5. Warning Statements FCC Part 15.21 Warning Statement- NOTE: THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT. FCC Part 15.19 Warning Statement- (Required for all Part 15 devices) THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. FCC Part 90.203(e) Compliance This radio complies with 47 CFR Part 90.203(e) in that the operator cannot program and transmit on frequencies, other than those stated by the manufacturer, service or maintenance personnel, using the equipment's external operation controls. It is noted that the FCC rules would be violated if this radio is used to operate on frequencies outside of FCC (Part 90 and Part 22) Frequency Bands for users other than the (Federal Government). FCC RF Exposure Requirements CAUTION: This transmitter must be restricted to work related operations in a Controlled RF exposure environment. All qualified end-users of this device must have the knowledge to control their exposure conditions and/or duration, and the exposure conditions and/or duration of their passengers and bystanders, to comply with the General Population / Uncontrolled MPE limit and requirements. Vehicle – Antenna Installation Instructions The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 1.8m from all persons, must not be co-located or operating in conjunction with any other antenna or transmitter, and must not exceed an antenna gain of 0 dBi with a minimum cable loss of 1dB. The antenna used for this transmitter must be mounted on the center of the roof ONLY and must be installed in vehicle having the following characteristics in order to prevent bystanders or passengers from being exposed to levels exceeding the limits set for General Population/Uncontrolled Exposure environment: 4 · All passengers must be sitting under a solid metal roof · Rooftop width must be at least 153.5 inches (or 3.9m) OR the edges of the physical boundary of the vehicle must be at least 3.9m apart. Failure to observe these restrictions will result in exceeding the FCC RF exposure limits. IC RSS-GEN, Sec 7.1.2 Warning Statement- (Required for Transmitters) ENGLISH: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. FRENCH: Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée quivalente (p.i.r.e.) ne dépassepas l'intensité nécessaire à l'établissement d'une communication satisfaisante. IC RSS-102, Sec 2.6 Warning Statements ENGLISH: The applicant is responsible for providing proper instructions to the user of the radio device, and any usage restrictions, including limits of exposure durations. The user manual shall provide installation and …
