This radio is supplied with a universal mounting bracket. When mounting the bracket and radio to your car, make sure it is mechanically strong. Also, provide a good electrical grounding connection to the ch assis of vehicle. Proceed as follows to install the radio. 1. Locate a convenient area in your vehicle for the installation of the radio. Hold the mounting bracket with the radio in the location where the radio is to be installed. Make sure nothing will interfere with eith er the radio or the mounting bolts. Mark and then drill holes for the mounting bracket. 2. Most radio antennas come equipped with a PL-259 plug. Connect this plug to the ANT. Jack in the rear of the radio. 3. Extending from the rear of the radio is a fused red and black wire for the DC connections to the vehicle’s electrical syst em. For best performance, it is strongly recommended that the red lead be taken directly to the positive terminal on the vehicle’s battery and the black lead be connected to the near est chassis ground. (Note: This radio is designed for vehicles with negative ground systems .) Connections should be made using appropriate “crimp on” lugs of a size large enough to make good contact with the bolt used to fasten to the battery and the chassis ground. It is a good safety idea to install a second fuse that would provide protection in case the red wire was to “fray” or get pinched and short to the body of the vehicle, somewhere betw een the battery and the radio. High power radios such as this one requir e large DC current flow when in the TX mode. Poor power connections cause supply voltage drops that can substantially decrease the performance of your radio. A good DC connection is probably one of the most important things for getting the best transmitter performance and in some cases, least receiver noise. 4. Mount the microphon e bracket near the radio in an easily accessible spot using the two screws provided. - 4 - IGNITION NOISE INTERFERENCE With weak signals, you may experience interference of the signal by background noise. This radio has NB and ANL circuits which will help reduce background noise from sources such as your ignition system. However, background electrical noise may come from several sources and all noise may not be eliminated. With extremely weak signals, you can operate this radio with the engine turned off, which should improve reception. If the ignition noise level is too high to allow proper operation under most conditions, you should have your installation of the radio checked by a qualified technician. ANTENNA This radio has a jack in the rear for a standard PL-259 antenna plug. If you are looking for the most range for your transm ission, use a vertically polarized, quarter- wave length antenna. If antenna height is a problem, you may use a shorter, loaded-type whip antenna although you can e…

APPLICANT: RANGER ELECTRONIC ( SHANGHAI) INC. FCC ID: MEE-DX-929 OPERATIONAL DESCRIPTION: The Ranger Electronic Model DX-929 is a Single Sideband/Amplitude Modulated transmitter/receiver combination intended for mabile operation in the citizens radio service. The transmitter has 40-channel capability in the 26.965 – 27.405 MHz band using phase locked loop (PPL) technology. The PPL provides multiple frequencies from the VCO (Voltage Controlled Oscillator) with quartz crystal accuracy and stability locked to the crystal oscillator reference frequency. The reference crystal oscillator, Q25, frequency is 10.240 MHz. Each channel is capable of operating in the AM/USB/LSB mode. Frequency tolerance is maintained within a frequency tolerance of 0.005%. Audio from the microphone is fed to a microphone amplifier, IC7. The audio is mixed at IC9, the transmitter mixer, with a signal from the Synthesizer. The mixed signal is routed though a low pass filter consisting of L28, 29, and 30. The 27 MHz signal is then fed to a transmit/receive relay circuitry to the antenna. Q46 is an oscillator operating at 10.697 MHz. Q25 is an oscillator with a frequency of 10.240 MHz. The mixer oscillator is Q27 and has a frequency oscillating at 15.36 MHz. The final amplifier is a 27 MHz High Frequency Power Amplifier consisting of a NPN Epitaxial Planar Silicon Transistor. The collector dissipation, Pc is specified at 1.2 Watts and 10 Watts at Tc=50ºC. See the attached DX-929 Block Diagram for additional circuit information.
