无线对讲机写频技术及软件设定方法
【对讲机的那点事】无线对讲机写频技术及软件设定方法对讲机写频技术，是经销商和业余无线电爱好者操作对讲机和电台的一种必须技能。
国产品牌对讲机机型繁多，写频软件是五花八门，要想和其它型号对讲机对频使用，写频难，难写频，对于经销商和无线电爱好者们，都是一个很头疼的问题。
国产对讲机软件官网难寻，一般是没有软件下载。
就是网上找到写频软件，下载安装后，能不能用都又是一个问题。
国内部份生产厂家，网上根本没有相应的软件下载。
还有些机型是专用写频线，引角定义不一样，根本不能读写频。
今天小编就和您聊聊关于对讲机写频的那些事：一、写频线接口定义对讲机写频线和耳机插孔定义是有很多种类，分为常用机型和专用机型。
K健伍系列：健伍好易通灵通泉盛特易通等市面上大多数国产机型T系列：A8：适用于摩托罗拉A8，A6，SMP418等机型M系列：TC500：适用于好易通窄口TC500/TC600/TC700等手台B系列：VX168：适用于威泰克斯系列VX-168，VX-160和部份单孔国产手台F系列：GP88S：适用于摩托罗拉GP88S/GP2000/GP3688等手台Y系列：V8：适用于IC-V8/V82/V85/F21/IC2720/F26等手台R系列：八重州3R/6R/7R等相关机型水晶头系列：特别注意：摩托GP88、北峰、健伍271、GM300等部份机型是专用写频线，写频线接口线定义不一样，不能通用的。
二、写频软件的安装安装方法，直接双击写频软件压缩包，解压软件，根据界面提示操作，点击下一步，安装到桌面和C盘，部份软件只能按装到C盘，安装到其它盘无效。
健伍等部份系列写频软件解压安装过程中，还要输入软件序列号。
在解压界面上最下一个就是安装软件序列号，直接把它复制、粘贴到那个安装框内，点击下一步安装完成。
国产大部份写频软件是一次直接解压，自动安装到位。
软件安装完成后，桌面和C盘区，有一个写频软件相应的界面。
双击打开写频软件操作界面，就可以进入写频模式。

对讲机制作的成败，除了与理论、经验、准确的工作频率和正确的调试方法等人为因素外，还有个关键的元件的质量问题，就是其中某个元件质量欠佳，可能会使您经过几个不眠之夜的奋斗，也未必能成功，根据笔者十多个对讲机的制作心得，接收机的灵敏度与N1，N2关系最密切。N1、N2除了与它们的高频特性有关外，还有个重要的参数是它们的噪声系数，普通的s9018等廉价高频管噪声系数均较大，难以实现预期的灵敏度。

不是的，对讲机使用写频线是为了给对讲机写频，而写频是在您需要更改对讲机频率是才进行的操作。基本上对讲机都有搜索（扫描）但是没有显示屏的对讲机扫描是在固定频率扫描，也就是在信道里面扫描，只有15个。而带显示屏有数字按键的，对讲机就有频率扫描。范围更大！它不会自动锁住频率，需要您人工操作！的确很慢，这功能不实用！
此外，高频功率管是否选用频率越高越好呢?例如有些爱好者乐于采用象2SC1971，2SC1972等高达175Mt{z的VHF频段的管子，笔者不推荐使用频率过高的功率三极管，第一是因为这样的管子价格相当昂贵。第二是频率过高，电路反而容易自激，不易于调试。笔者就遇到这样的问题，在台式机中使用2sc1969，电路工作相当正常，功率也可达到8w左右，都使用了很长时间。后改为2sc1971，电路却严重自激，花了很大的功夫，采取了很多措施才能以解决，实际输出功率与2SC1969基本无异。

RTX-RTLP 434, normally presents, at the data output, 1 and 0 random commutations, corresponding to the noise generated by the transceiver itself.Such characteristic allows to make use of the maximum sensibility of the device. However, in certain application, where a low noise level is required, it is possible to connect a resistance of X value (see table) between transceiver T.P. pin and GND.The table here below shows for different resistance value, the obtained loss value:Model Loss (–1dB) Loss (-3dB) RTX-RTLP 434Rx = 10MRx = 5.6MFig. 2 Attenuation curve according to RX valueFig. 1RTX-RTLP434Instruction ManualBy accepting some commutation on the data output, it suffice to apply a resistance value that determines a 1 dB attenuation; attenuations of 3 dB increase the immunity to the noise till to obtain, to the data output, a logic, low and stable value in lack of RF signal.Device usageIn order to take advantage of the performances described in the technical specifications and to comply with the operating conditions which characterize the Certification, the transceiver has to be fitted on a printed circuit, considering what follows:3 V dc supply:1. The transceiver must be supplied by a very low voltage source, safety protected against short circuits.2. Maximum voltage variations allowed: ± 0,15 V.3. De-coupling, next to the transceiver, by means of a minimum 100.000 pF. ceramic capacitor.Ground:1. It must surround at the best the welded area of the transceiver. The circuit must be double layer, withthroughout vias to the ground planes, approximately each 15 mm.2. It must be properly dimensioned, specially in the antenna connection area, in case a radiating whipantenna is fitted in it (an area of approximately 50 mm radius is suggested.)50 Ohm line:1. It must be the shortest as possible.2. 1,8 mm wide for 1 mm thick FR4 printed circuits and 2,9 mm wide for 1,6 mm thick FR4 printed circuits.On the same side, it must be kept 2 mm away from the ground circuit. 3. On the opposite side a ground circuit area must be present.Fig.3 Suggested lay-out for the devicecorrect usageRTX-RTLP434 Instruction Manual Antenna connection:1. It may be utilized as the direct connection point for the radiating whip antenna.2. It can bear the connection of the central wire of a 50 Ω coaxial cable. Be sure that the braid is welded tothe ground in a close point.Antenna:1. A whip antenna, 16,5 mm long and approximately 1 mm dia, brass or copper wire made, must beconnected to the RF input of the transceiver.2. The antenna body must be keep straight as much as possible and it must be free from other circuits ormetal parts (5 cm minimum suggested distance.)3. It can be utilized either vertical or horizontal, provided the connection point between antenna andtransceiver input, is surrounded by a good ground plane.N.B:As an alternative to the a.m. antenna it is possible to utilize the whip model manufactured by Aurel (see related Data Sheet ed Application Notes).By fitting whip antennas too different from the described ones, the EC Certification is not assured.Other components:1. Keep the transceiver separate from all other components of the circuit (more than 5 mm).2. Keep particularly far away and shielded all possible microprocessors and their clock circuits.3. Do not fit components around the 50 Ohm line. At least keep them at 5 mm distance.4. If the Antenna Connection is directly used for a radiating whip antenna connection, keep at least a 5 cmradius free area. In case of coaxial cable connection then 5 mm radius will suffice.Reference RulesThe RTX-RTLP 434 transceiver is EC certified and in particular it complies with the European Rules EN 300 220-3 for class 2, and EN 300 683 for class 1. The equipment has been tested according to rule EN 60950 and it can be utilized inside a special insulated housing that assures the compliance with the above mentioned rule. The transceiver must be supplied by a very low voltage safety source protected against short circuits The use of the transceiver module is foreseen inside housings that assure the overcoming of the rule EN 61000-4-2 not directly applicable to the module itself. In particular, it is at the user’ s care the insulation of the external antenna connection, and of the antenna itself since the RF output of the transceiver is not built to directly bear the electrostatic charges foreseen by the a.m. rule.CEPT 70-03 RecommandationsIn order to comply with such rule, the device (strictly for what it concernes the tranbsmission phase) must be used only for a 10% of an hourly duty-cycle, (that means 6 minutes of utilisation over 60).The device usage inside the italian territory is governed by the Codice Postale and Telecomunicazioni rules in force (art. no. 334 and subsequents).The technical tests and reports have been carried out and obtained by the laboratories of :Messrs PRIMA RICERCA & SVILUPPO – via Campagna, 58 – 22020 Gaggino Faloppio (CO) - Italy I。
常数扇宽技术（Constant Beamwidth Technology）音响系统用户指南说明书
CBT 100LA-LSKey Features:Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.EN54-24 Compliant (when installed with included MTC-PC2 panel cover).Vertical pattern coverage switchable between 40° formedium-throw coverage and 15° for long-throw applications.Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.Dynamic SonicGuard™ overload protectionSwivel (pan)/tilt wall bracket included.Built-in 70V/100V transformer, plus 8 ohm direct capability.Line Array Column Loudspeaker with Sixteen 50 mm (2 in) Drivers and EN54:24 CertificationOverview:The CBT 100LA-LS, with Constant BeamwidthTechnology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.The slim, compact design fits well into virtually anyarchitectural decor. The 100 cm (39.4 in) tall line array height provides consistent pattern control throughout the intelligibility band, making the CBT 100LA-LS ideal for difficult acoustic environments. The combination of superior sound quality,excellent pattern control, and compact design makes CBT 100LA-LS ideal for applications such as lecture halls, transit centers, conference rooms, cathedrals, multipurpose spaces, architectural spaces, and in-wall recessed locations, among many others.The innovative coverage adjustability allows switching between broad and narrow vertical coverage settings to allow matching the coverage and throw requirements of the application. Coverage can be easily switched in-venue with the speaker alreadyinstalled. This innovation allows a single loudspeaker model to excel in an extremely wide variety of project types.The voicing can be set to match the application through the Music/Speech switch. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances.The drivers feature dual neodymium magnets for light weight. Copper capped pole pieces lower both the driver inductance and the flux modulation, resulting in increased high frequency extension and reduced distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments. The drivers are shielded.Dynamic SonicGuard™ minimizes distortion at high drive levels by limiting low frequency excursion dynamically.

威世-OTS 1 同轴电缆连接器 PCB 传输线设计指南 应用笔记 ANE012说明书
ANE012 // O LAN T SAI1IntroductionThe function of a RF (Radio Frequency) transmission line is a directing RF signal from a source to a load with minimal loss and distortion. Impedance plays an important role in signal transmission. Even if the trace impedance already matches, adding a connector can cause an impedance mismatch and thus signal distortions due to reflections. The purpose of this application note is to outline methods for improving signal transmission when a connector is added on a PCB.1.1.ImpedanceImpedance matching determines the transmission line performance. Characteristic impedance of a standard transmission line is expressed as:Z0=�R+jωLG+jωCAccording to the formula above, the main factors include: R(resistance per meter), L(inductance per meter), C(capacitance per meter), G(conductance per meter), and last but not least the angular frequency ω.1.2.Types of RF Transmission line on PCBApplications define the selection of suitable types of transmission lines:Embedded Strip LineThere are ground planes above and below, and thedielectric around the trace is homogeneous. Microstrip Line The dielectric material above the trace is different from thatbelow the trace. There must be a gound plane bel o w thetrace, while a grould plane above the trace may be omitted.Commonly applied on test PCBs.Coplanar Waveguide withGroundThe complanar wave guide basically consists of the signaltrace with the two adjacent GND traces on the left and right.Additionally there might be a ground under the coplanarwaveguide to reduce the parasitic discontinuities. Thisstructure is common use in applications that need toconnect to a RF connector or an antenna. The ground pl a neadditionally helps to shield the transmission line againstparasitic couplings to close metal objects.Figures 1 to 3 – Types of RF transmission lines2RF Transimission Line Design Parameter _________________________________________The coplanar waveguide with ground is typically found on PCBs with a coaxial connector; therefore, we use this RF transmission line as example.Figure 4: Coplanar waveguideFactors that determine the PCB transmission-line characteristic impedance are:εr Dielectric constant of the substrateW Conductor widthH Substrate hightT Conductor thickness (copper thickness)D Distance of the signal conductor to the coplanar ground stripscεr Dielectric constant of the coating (solder resist)Table 1: Influencing factors on characteristic impedanceSuggested design flow for a RF transmission line is as follows:a)Select the PCB substrate.▪For example: FR1, FR4, CEM1…etc.b)Define the PCB’s properties:▪εr: Substrate dielectric constant▪H: Substrate height▪T: Trace thickness▪Cεr: Coating dielectric constantc)Control and adjust the value of W and D to reach the required characteristic impedance.d)If step (c) cannot be achieved, please return to step (b) to select a different substrate height and trace thickness. Return to (a)when the newly selected properties in step (b) still cannot achieve the desired impedance.3 Relationship for Each Parameter with Characteristic Impedance ________________________It is important to understand how each factor influences the transmission line.Each paragraph below indicates how the characteristic impedance will change when only one of these factors is adjusted.3.1. εr - Substrate Dielectric ConstantMany different types of materials can be used as PCB substrate. Each substrate has its own dielectric constant. The user needs to be aware of “PCB Material Dielectric Constant” given by manufacturers.On the other hand, material dielectric constant will vary not only between vendors but with the frequency, too.FR-1 5.5-6 FR-4 4.2-4.7 CEM-1 4.6 CEM-35.0Table 2: Dielectric constants for common PCB materialsFigure 5: This figure shows impedance (Z 0) is inversely proportional to dielectric constant (εr )3.2.W- Trace WidthFor trace width design, the user needs to consider four things:1) Narrow traces are more difficult to control2) Wider traces need more space on the PCB.3) Actual trace width may not be as designed due to manufacturing tolerance.4) Because the wave impedance and the height of the dielectric material is fixed, these parameters will decide the trace width.Figure 6: This figure shows impedance (Z0) is roughly inverse-proportional to trace width3.3.H- Substrate HeightThe substrate height is the distance between the ground and signal layer of a PCB. The characteristic impedance reduces if the copper layers are closer together and the other parameters are fixed. To maintain the impedance of the trace, the trace width can be reduced. This in turn saves space on PCB. But please note, if narrower tracks are used, the tolerance of the impedance will be greater due to the undercutting during manufacturi n g process!Figure 7: Impedance (Z0) increases more slowly when substrate height is at specific distance3.4.T- Trace Thickness (height of the copper layer)Copper is commonly used as the PCB metal layer in layer heights of 0.5 oz/ft2 (0.017mm), 1 oz/ft2 (0.035mm) or 2 oz/ft2 (0.070mm). The characteristi c impedance reduces, if the Cu copper thickness (height of the copper layer) is increased.Figure 8: Impedance (Z0) is roughly inverse-proportional to the trace thickness (height of the copper layer)3.5. D- Distance between Trace and Coplanar GroundThis factor is very sensitive. It can influence the impedance by 1~2 Ω with only 0.01 mm variation, hence the PCB manufacturing precision needs to be checked when doing this adjustment.Figure 9: Impedance (Z0) is roughly proportional to the distance between trace and coplanar ground3.6. C εr - Coating Dielectric ConstantThe coating material’s permittivity also has an influence on characteristic impedance. It should be considered early in the design stage in order to avoi d deviation from calculated values.Figure 10: Impedance (Z 0) is roughly inverse-proportional to the coating dielectric constant4 Connector Pin Contact to PCBWhen the connector center pin is connected to the PCB trace, it adds a certain height on top of the PCB trace due to its defined size. This hei g ht creates a discontinuity and should be fixed by adjusting the trace width on PCB.4.1. End Launch Round Post PinFigure 11: Round post connectors have a larger center pin which creates significant discontinuity after soldering.To match with the “microstrip line”, the trace width needs to be changed to fit with the round post pin.Figure 12: Example of modify the trace shape to improve matching.If the impedance value is too low from the ideal matching impedance, try to use the shape shown on the left side of figure 12. The trace width near the connector center pin must be reduced. Making the trace width narrower at the end will make a better match.For a coplanar waveguide, the impedance value can be increased by increasing the distance between the trace and its coplanar ground (GND). It is also possible to reach the ideal impedance by reducing the width of signal trace.Figure 13: Example of increase the gap distance to improve impedance matching.4.2. End Launch Flat Tab PinThis connector usually has a smaller center pin and has less influence on impedance discontinuity after soldering. When the flat pin makes the impedance lower, it can be raised by reducing the width of trace or increasing the gap distance between trace and its coplanar ground (GND).Figure 14: End Launch Flat Tab PinFigure 15: Example of reduced trace width to improve impedance matching4.3. THT Pin & SMT PinTHT and SMT connectors are more difficult to reach the ideal match. This is often caused by the gap after the connector is soldered on to PCB. Thegap will make the impedance value higher.Figure 16: Gap between PCB and connectorFurthermore, THT and SMT connectors that are perpendicular to the trace on PCB which make the impedance lower. For THT center pin, the extended connector legs will make the impedance value lower. Impedance discontinuity occurs over a very short distance for THT and SMT connectors, whi c h is more difficult to fix by adjusting the traces on PCB.THT and SMT connectors are normally not used in very high-frequency products, because of impedance matching issues.How the signal is routed from a THT connector changes the impedance.Figure 17: Signal route: Connector interface PCB traceFigure 18: Impedance in time domain 1. Gaps make the impedance higher2. Vertical area and extended center contact make the impedance lowerHow the signal is routed from a SMT connector changes the impedance.Figure 19: Signal route: Connector interface PCB traceFigure 20: Impedance in time domain 1. Gaps make impedance higher 2. Vertical area makes impedance lower4244464850525456I m p e d a n c e (Ω)TimeImpedance VaryExtended center contact①②Figures 17 to 20 show the impact of the connector construction and its connections to the PCB in the time domain. It was measured with a time-domain reflectometer (TDR) which determines the impedance of the measured construction by observing the reflected waveform. The change of the impedance over time can be recalculated via εr to the point of reflection.How to Improve:1) Gaps make the impedance higher: Use solder paste to fill up gaps to improve the impedance.Figure 21: Use solder paste to fill up gaps2) Vertical area makes the impedance lower: Increase the gap between the contact pin and the GND to reduce the impedanceFigure 22: Layout modification to improve the matching3) Extended connector legs make the impedance lower:Extended connector legs not only make the impedance value lower, they might also cause an antenna effect. Methods to solve this are: ▪ Select the connector pin length to better match PCB thickness. ▪Cut long legs for a significant improvement.5 Other factors affecting the impedanceFollowing a few points that will influence the transmission line impedance when making a PCB:5.1. PCB cut Line(End Launch Coaxial Connector Issue)PCB routing tolerances occur during PCB production. If the ground layer does not extend to end of the PCB, the PCB routing tolerance might cause a gap between PCB and the connector which will cause an impedance discontinuity.Figure 23: Ground not extended to end of the PCBFigure 24: After soldering the connector, a gap exist without groundWe would suggest extending the ground layer on the connector side to the edge. If PCB routing tolerances issues occur, there will be no gap after the connector is soldered to the PCBFigure 25: Extended ground to the end of the PCB5.2. PCB Trim Line (End Launch Edge Card Coaxial Connector Issue)The PCB routing cannot cut a sharp right angle and the round corners might cause a gap between the connector and the PCB. Because they coul d not meet closely this causes an impedance discontinuity (figure 25). To fix this, we suggest using Ø0.6-2 mm relief holes in the corners in order to remove the corner radius, as displayed in figure 26.Figure 25: Round corners cause poor mechanical matching of the connectorFigure 26: additional holes improve the fit of the connector5.3. End Launch Connector and the Backside of a PCBWhen an end launch connector is placed on a PCB, if the copper layer is not extended to the PCB edge, there would be a small gap in between. Use of solder paste to fill up the gap can be helpful to impedance control (figure 27).Figure 27: Use solder paste to fill up the gap5.4. Via HoleWhen using a coplanar waveguide design, it is suggested to add some via holes to the coplanar GND surrounding the trace, as shown in figure 28. The via holes connect the upper traces and the bottom layer which is the ground layer. Depending on the highest signal frequency, the vias shoul d have a distance of not more then 2 – 4 mm to make sure, that the coplanar GND-traces keep their GND potentialFigure 28: Via implementation from the coplanar ground traces to the ground (GND) layer6 Simulation Examples60312202114509PCB End Launch Jack Round Post for 1.6mm PCBFigure 29: Original DesignFigure 30: Matching DesignIncrease the gap between trace and ground to increase the impedance and reach impedance matchingVia HoleResult of TDR measurement (Original Design):Lower impedance in thearea of contactingFigure 31: Result of TDR measurement (Original Design) Result of TDR measurement (Matching Design):Figure 32: Result of TDR measurement (Matching-Design)Result of S-Parameter measurement (Original Design):Figure 33: Result of S-Parameter – VSWR measurement (Original Design)Figure 34: Result of S-Parameter - Return Loss measurement (Original Design)Result of S-Parameter measurement (Matching Design):Figure 35: Result of S-Parameter - VSWR measurement (Matching Design)Figure 36: Result of S-Parameter – Return Loss measurement (Matching Design)7ConclusionSimulation software is very useful when designing a transmission line, Software like AppCAD, for example, can simulate transmission lines with different factors. Using the result from AppCAD, software like HFSS can provide full-wave simulations, including both connector and PCB. Overall, usi n g simulation software can save a lot of time.Knowing the preciseness of PCB production will also help the user design a transmission line because most transmission lines are very narrow. If the PCB has wide tolerances from production, the user’s test results will have huge difference compared to software simulations. Sometimes, roughness of copper layer is a factor that affects impedance of transmission line.The quality of a transmission line is one part of transmission quality in a product. Users now should understand how to enhance transmission l i n e quality after reading through these suggestionsI M P O R T A NT NO T I C EThe Application Note is based on our knowledge and experience of typical requirements concerning these areas.
