OBJ-1255Dual Band Vehicle Radio

Installation of Transceiver Select a safe and convenient site in your vehicle so as to reduce possible damage to your passenger or yourself during vehicle movement. You may install the transceiver blow the dashboard in front of the front passenger seats so that your knees and legs will not collide the transceiver in case of emergency brake. It’s best to select a well ventilated location which is shielded from direct sunlight. 1. Use the supplied self-tapping screws (4X) and flat washers (4X) to install the mounting bracket in the vehicle as shown in Fig. 1 and Fig. 2. Fig. 1 Fig.2 Fig. 3 2. Fix the transceiver, and then insert and tighten the supplied hexagonal screws (4X) as shown in Fig. 3. z Make sure all screws are tightened to avoid loosening of the bracket or the transceiver in vibration of vehicle. z Use the 3 screw grooves at the side rear side of each bracket to install the main body at a proper inclined angle as shown in Fig., 4, 5 and 6. Fig. 4 Fig. 5 Fig. 6 Power Cable Connection „ Operation of transceiver Be sure to use 12V vehicle batteries with sufficient electricity. If the electricity is insufficient, the display screen may darken or the transmission output power may greatly drop during the transmission. Do not connect the transceiver to 24V batteries. Note: If you use the transceiver when the vehicle-use batteries are not sufficiently charged or the engine is off, battery discharge may lead to insufficient electricity quantity, making it difficult to start the vehicle. Therefore, try to avoid using the transceiver in such situation. 1. Use the DC power cable supplied with the transceiver to connect the transceiver with the vehicle battery terminal in a shortest route. z It is suggested not to use a cigar lighter outlet as much as possible as some of them may lead to great voltage drop. z The whole power cable must be wrapped up to isolate it from heat and moisture and from the engine ignition system/connection wiring. 2. When the power cable is installed in place, wind the fuse holder with heat-resistant adhesive tape to protect it against moisture. It’s better to use heat-resistant adhesive tape to wrap the whole power cable. 3. To prevent short-circuit, disconnect the other connection wirings at the negative (-) battery terminal before connecting the transceiver. 4. Please confirm the correct polarity of connections before attaching the power cable to the battery terminal. Connect the red wire to the positive (+) terminal of battery and the black to the negative (-). Vehicle body Mounting bracket Cone screw Wa s h erM5 z Use the full length of power cable without cutting off the excess even if it is longer than needed. Remember not to remove the fuse holder from the cable. 5. Reconnect all connection wirings removed from the negative terminal previously. 6. Connect the DC power cable to the transceiver. z Plug in the outlet and keep pushing firmly until the locking tab clicks. „ Operation of fixed radio station If you intend to use the transceiver as a fixed radio station, you need to buy an independent 13.8 DC power supply separately with a suggested continuous current capacity of above 12A. Note: z Do not connect this DC power supply to the AC power outlet before all connections are completed. (Do not connect the transceiver when it’s powered on.) z Please connect all cables before inserting the DC power supply device into the AC outlet. 1. Be sure the transceiver and the DC power supply are off. 2. Connect the DC power supply cable to the DC stabilized power supply and make sure the polarities are correct (red: positive, black: negative). z Do not directly connect the transceiver to the AC outlet. z Use the supplied DC power cable to connect the transceiver to a DC stabilized power supply. z Do not use a power cable with the specification and parameters lower than the original power cable. 3. Connect the DC power cable to the transceiver. ‹ Plug in the outlet and keep pushing firmly until the locking tab clicks. Only use fuses of specified type and rated value. Otherwise, the transceiver may be damaged at your own risk. Connecting Antennas Before operation, install a highly efficient and well-tuned antenna. Successful installation depends largely on the correct antenna type and installation. If a proper antenna system is selected and installed correctly, the transceiver will achieve best performance. Use an antenna with a characteristic impedance of 50Ω and a low loss coaxial feeder with 50Ω characteristic impedance to match the input impedance of the transceiver. Using a Attention Red Black feeder whose impedance is not 50Ω to connect the antenna with the transceiver will reduce the performance of the antenna system, and may cause interference to the nearby radio and TV receivers, radio receivers and other electronic devices and even damage the transceiver. ‹ Transmitting without connecting antenna or other matched load is prohibited. Otherwise, the transceiver will be damaged. Be sure to connect the antenna to the transceiver before transmitting, and only when the connection is confirmed can the transmission be made. ‹ All fixed radio stations must be equipped with a lightning arrester to reduce the risk of damaging the transceiver by fire or electric shock. The location and mounting mode of the antenna on the vehicle are shown as follows: Attention

BJ-UV55 CIRCUIT DESCRIPTION 一、Receiver Signal Path 1、RF signal „ UHF band signal UHF signal is passed through a high-pass filter network and a low-pass filter network to the antenna switch diodes D303、D304，then passed through BPF tuned filter circuit（D306， D308） to UHF band RF amplifier T300. The amplified UHF signal is passed through another BPF tuned filter circuit(D309, D310) , then is passed through the first mixer T301. Meanwhile, the UHF local signal from the UHF-VCO(T402) is delivered to first mixer T301, yielding the UHF band first IF frequency 38.55MHz . „ VHF band signal VHF signal is passed through a low-pass filter network and a high-pass filter network to the antenna switch diodes(D314, D315 & D317). Then passed through another low-pass filter network to the VHF band RF amplifier T303, yielding the VHF band first IF frequency 38.55MHz. 2、IF and AF Signals UHF band and VHF band first IF frequency 38.55MHz is delivered to the crystal filter FL500, F501 through switch(D301, D313) which strips away unwanted mixer clutter, then is passed through IF amplifier T501 to the IF IC U500. Meanwhile, output of 13.0MHz TCXO crystal CR 400 is multiplied threefold by T502 to output the 39MHz second local signal, then delivered to the IF IC U500. Within the IF IC U500, the 39MHz second local signal is mixed with the 38.55MHz first local signal to produce the second IF frequency 450KHz. The 450KHz second IF is passed through the filter switch D501 to the ceramic filter FL 503 which strips away all but the desired signal, then it passes through the IF amplifier within U500 to the ceramic discriminator CR500, which removes any amplitude variations in the 450KHz IF signal before detection of speech. The demodulated audio signal is passed through audio volume potentiometer VR1 to adjust the audio sensitivity and then is delivered to the U900 to be amplified and applied to the loudspeaker. 3、Squelch Control When no carrier is being received, noise at the output of the detector stage in U500 is amplified and band-pass filtered by the noise amp section of U500. The resulting DC voltage is delivered to CPU(U801), which compares the squelch threshold level to that which set by Menu. While no carrier is being received, CPU will output a controllable level, to disable the audio output from the speaker through T901. 二、Transmitter Signal Path 1、AF Signal The speech signal from the microphone is passed through the MIC jack J1 to the AF amplifier U600. The amplified speech signal is delivered to the limiting amplifier T601, T602 to prevent over-modulation, then is delivered to a low-pass filter network. „ UHF band The adjusted speech signal is passed through varactor diodes D402 which frequency modulate the transmitting VCO, made up of UHF-VCO T407. The modulated transmit signal is passed through buffer amplifiers T402、T400 and diode switches D201、D1011 to the pre-drive amplifier T1002. The amplified transmit signal from T1002 is passed through diode switch D1013 and the driver amplifier T1003 to the diode switch D1014, then finally amplified by power amplifier TH1005, providing up to 35 Watts of power output. These three stages of the power amplifier are controlled by the APC circuit. The 35 Watts RF signal is passed through a high-pass filter network to the antenna switch D1005, D1004 and D1003, then passed through a low-pass filter network and another high-pass filter network to the ANT jack. „ VHF band The adjusted speech signal is passed through varactor D407, which frequency modulate the transmitting VCO, made up of VHF-VCO T408. The modulated transmit signal is passed through buffer amplifiers T403, T404 and diode switches D200, D1010 to the pre-drive amplifier T1002. The amplified transmit signal from T10002 is passed through the diode switch D11012, D11013 and drive amplifier T1003 to the diode switch D1017, then finally amplified by power amplifier TH1005, yielding the output power which is higher than 50W. These three stages of the power amplifier are controlled by the APC circuit. 50Watts RF signal is passed through a low-pass network to antenna switch D1001 and D1002, then is passed through a high-pass network and another low-pass network to antenna jack. 2、APC(Automatic Power Control) Circuit „ UHF band A portion of the power amplifier output is rectified by D1008 and D1009, then delivered to APC U1000. As a DC voltage which is proportional to the output level of the power amplifier. At U1000, the rectified DC voltage from the power amplifier is compared to the reference voltage from the main CPU U801 to produce a control voltage which regulates the supply voltage to the pre- amplifier T1002, drive amplifier T1003 and power amplifier TH1005, so as to maintain stable output power under varying antenna loading conditions. „ VHF band A portion of the power amplifier output is rectified by D1006, D1007, then delivery to APC U1000.

Federal Communications CommissionDA 13-431 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended Promotion of Spectrum Efficient Technologies on Certain Part 90 Frequencies ) ) ) ) ) ) ) WT Docket No. 99-87 RM-9332 ORDER Adopted: March 15, 2013Released: March 18, 2013 By the Chief, Wireless Telecommunications Bureau, Chief, Public Safety and Homeland Security Bureau, and Chief, Office of Engineering and Technology: 1.Introduction.In this Order, we grant in part and deny in part a Petition to Delay Indefinitely Implementation of Section 90.203(j)(5) of the Commission’s Rules filed by Ritron, Inc. (Ritron) on September 21, 2012. 1 Pursuant to Section 90.203(j)(5) of the Commission’s rules, the Commission no longer accepts applications for certification of Part 90 private land mobile radio (PLMR) equipment in the 150-174 MHz and 450-512 MHz bands that cannot operate in a 6.25 kHz mode or with equivalent efficiency. 2 Ritron requests that implementation of this requirement be delayed indefinitely. We conclude that the requirement should be waived only until January 1, 2015. 2.Background.In 1995, the Commission adopted rule changes to promote the efficient use of the PLMR service and facilitate the introduction of advanced technologies. 3 To promote the transition to a more efficient narrowband channel plan, the Commission provided, inter alia, that “only increasingly efficient equipment” would be approved. 4 The Commissiondid not set a date after which it would no longer approve equipment with a wideband (25 kHz) mode, or after which such equipment could no longer be manufactured or used. 5 The Commission contemplated that, as systems reached the end of their service life and new radios were needed, users would migrate to the narrower bandwidth multi-mode radios in order to avoid the adjacent-channel interference that could occur from systems using the adjacent narrowband channels. 6 3.Subsequently, the Commission determined that the 1995 rules failed to provide adequate incentive to realize the Commission’s spectrum efficiency goals in these bands, and stronger measures 1 SeePetition to Delay Indefinitely Implementation Section 90.203(j)(5) of the Commission’s Rules (filed Sept. 21, 2012) (Petition). 2 See47 C.F.R. § 90.203(j)(5). 3 SeeReplacement of Part 90 by Part 88 to Revise the Private Land Mobile Radio Services and Modify the Policies Governing Them, Report and Order and Further Notice of Proposed Rule Making, PR Docket No. 92-235, 10 FCC Rcd 10076, 10077 ¶ 1 (1995). 4 Id.at 10081 ¶ 7. 5 Id.at 10100 ¶ 40. 6 Id. Federal Communications CommissionDA 13-431 2 would be required to bring about a timely transition to narrowband technology. 7 The Commission therefore amended the rules to provide that, by January 1, 2013, Industrial/Business and Public Safety Radio Pool licensees in the 150-174 MHz and 421-512 MHz bands must migrate to 12.5 kHz channel bandwidth or utilize a technology that achieves equivalent efficiency. 8 4.The Commission also adopted interim deadlines to facilitate this transition to narrowband technology. Among other rules, the Commission provided that, beginning January 1, 2011, it would no longer accept applications for certification of equipment that cannot operate in 6.25 kHz mode or with equivalent efficiency. 9 In 2010, the Commission temporarily waived this requirement until January 1, 2013, 10 but stated, “If 6.25 kHz standards still are not in place at that date, interested parties may request a further extension.” 11 5.Ritron, a manufacturer of wireless products, contends that standards for 6.25 kHz technology are not yet in place and that other issues exist that justify delaying implementation of mandatory 6.25 kHz certification by manufacturers.Ritron states that no one 6.25 kHz equipment standard exists and that, in the Industrial/Business sector of the market, two incompatible and proprietary technologies have emerged. 12 Italso argues that 6.25 kHz equipment is still unduly expensive. 13 Finally, Ritron asserts that using the equipment authorization process to facilitate the transition to narrowband technology has been largely unsuccessful. 14 Itconcludes that the implementation of Section 90.203(j)(5) should be delayed until (a) a real need has been established for additional PLMR frequencies beyond those created by the transition to 12.5 kHz channels; (b) the benefits of 6.25 kHz outweigh the associated research and development, manufacturing, and product costs; and (c) a standard has emergedfor a more cost-effective voice compressor/decompressor (vocoder). 15 6.The Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau and the Office of Engineering and Technology sought comment on Ritron’s request. 16 We asked commenters to address whether the public interest would be served by further delaying implementation of 7 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended,Second Report and Order and Second Further Notice of Proposed Rulemaking, WT Docket No. 99-87, 18 FCC Rcd 3034, 3038 ¶ 12 (2003). 8 See 47 C.F.R. § 90.209(b)(5). The January 1, 2013 deadline for converting to 12.5 kHz technology has been waived for licensees in the 470-512 MHz segment of the UHF band (the T-Band).
