UV-5R 键盘手动编程UV-5R Keypad Programming
无需写频线与电脑，纯键盘完成频率与中继设置。Program frequencies and repeaters with the radio's own keys — no computer needed.
进入频率模式Enter Frequency Mode
开机后若屏幕显示 （信道模式），按 VFO/MR 切换到频率模式（纯数字频率，无 CH 标识）。所有编程必须从 A 屏幕上/频率模式下进行。
If the screen shows (channel mode), press VFO/MR to switch to Frequency Mode (plain number, no CH). All programming must be done from the A side / Frequency Mode.
一张图认全 UV-5R 按键UV-5R button & keypad map
关闭双守（TDR）Turn off Dual Watch (TDR)
按 MENU 7 MENU，设为 OFF，再 MENUEXIT。双守开启时常导致信道存不进去。
Press MENU 7 MENU, set to OFF, then MENUEXIT. Leaving Dual Watch on is a common cause of channels not saving.
输入接收频率Enter the receive frequency
用键盘直接输入频率，例如 146940 表示 146.940 MHz。若无法精确落到某频率，检查菜单 1 STEP 步进，设为 5.00 kHz。
Type the frequency directly, e.g. 146940 for 146.940 MHz. If you can't land on an exact frequency, set Menu 1 STEP to 5.00 kHz.
中继：设置频差与方向Repeater: set offset & direction
按 MENU 25 MENU 选偏移方向（+ / − / OFF）；MENU 26 MENU 输入频差（典型 2m=00600，70cm=05000）。
MENU 25 MENU sets shift direction (+ / − / OFF); MENU 26 MENU enters the offset (typical 2m=00600, 70cm=05000).
设置发射亚音Set transmit tone
中继若要求哑音：MENU 13 MENU 选 T-CTCS，输入哑音值（如 1035 = 103.5 Hz）。无需哑音则跳过。
If the repeater needs a tone: MENU 13 MENU, choose T-CTCS, enter the tone (e.g. 1035 = 103.5 Hz). Skip if no tone required.
存储到信道Save to a channel
按 MENU 27 MENU 输入信道号（000–127）保存接收频率。中继建议再手动输入发射频率（接收±频差）后，重复菜单 27 存到同一信道号——此法跨版本最稳。
MENU 27 MENU, enter a channel number (000–127) to save the receive frequency. For a repeater, also key in the transmit frequency (receive ± offset) and repeat Menu 27 to the same channel — most reliable across firmware versions.
验证Verify
返回信道模式，找到该信道应显示 + 或 − 符号；按 PTT 应见 CT 且频率变为偏移值。
Back in Channel Mode, the channel should show a + or −. Briefly press PTT and you should see CT and the frequency shift to the offset value.

UV-5R 频率设置（VFO/STEP）UV-5R Frequency Settings (VFO/STEP)
搞懂频率模式与步进，才能精准落到目标频点。Understand frequency mode and step so you can land exactly on target.
VFO（频率）与 MR（信道）VFO (frequency) vs MR (channel)
VFO 模式：直接输入/显示频率，用于临时通信与编程；MR 模式：显示已存信道号，用于日常通话。按 VFO/MR 切换。所有编程须在 VFO 下进行。
VFO Mode: type/show a frequency directly — for ad-hoc comms and programming. MR Mode: shows stored channel numbers for daily use. Toggle with VFO/MR. All programming happens in VFO.
步进（STEP）Step (STEP)
菜单 1 STEP 决定频率可落点间隔。常规用 5.00 kHz；要输入 7 位频率（如 146.24625）需设 2.5K。落不到精确频率时先调 STEP。
Menu 1 STEP sets the frequency increment. Use 5.00 kHz normally; for 7-digit frequencies (e.g. 146.24625) set 2.5K. If you can't land exactly, adjust STEP first.
输入与微调Enter & fine-tune
VFO 模式下用键盘直接输入频率（如 438500 = 438.500）。发射前可按住 MONI 监听，确认频率空闲再发。
In VFO, type the frequency directly (e.g. 438500 = 438.500). Before TX, hold MONI to monitor and confirm the frequency is clear.

UV-5R 接收范围与监听边界UV-5R Receive Range & Listening Boundaries
搞懂它能听什么、听不到什么，以及法律红线。Know what it hears, what it misses, and the legal red line.
UV-5R 比"双段"能听更多The UV-5R hears more than "two bands"
UV-5R 名义是双段（VHF 144–148 / UHF 420–450）手持，但接收范围其实宽得多：它是一台宽覆盖接收机，可以"听"到很多超出业余频段的信号。本页讲清能听什么、听不到什么、怎么扩展、以及法律边界。
The UV-5R is sold as a dual-band (VHF 144–148 / UHF 420–450) HT, but its receive coverage is far wider: it is a broad-coverage receiver that can listen to many signals outside the amateur bands. This page explains what it can hear, what it cannot, how to extend it, and the legal boundary.
一张图看懂接收与发射频段One diagram: receive vs transmit bands
UV-5R 接收范围远大于发射：默认 VHF 约 136–174 MHz、UHF 约 400–520 MHz（CHIRP 可将 VHF 下限扩展到 108 MHz 收听航空 AM），但发射被锁定在本地业余频段（2 m 144–148、70 cm 430–440）；174–400 MHz 多数机型不接收。数值为常见近似，以机型/地区为准。
The UV-5R receives far more than it transmits: default VHF ~136–174 MHz and UHF ~400–520 MHz (CHIRP can lower the VHF floor to ~108 MHz for aviation AM), but its transmit is locked to the local amateur bands (2 m 144–148, 70 cm 430–440); 174–400 MHz is not received on most units. Figures are common approximations — follow your unit and region.
默认接收范围Default receive range
多数 UV-5R 出厂接收覆盖约 136–174 MHz（VHF） 与 400–480 / 400–520 MHz（UHF），具体上限随批次/固件略有差异（以你机器为准）。在此范围内可收到：业余、部分海事 VHF（156–162）、航空（若已开启）、气象（162 MHz NOAA WX，部分机型支持）、PMR446/FRS/GMRS（446 / 462–467）、部分商业 UHF。
Most UV-5R units receive roughly 136–174 MHz (VHF) and 400–480 / 400–520 MHz (UHF); the exact upper edge varies slightly by batch/firmware (follow your unit). Within this you can hear: amateur, some marine VHF (156–162), aviation (if enabled), weather (162 MHz NOAA WX on some units), PMR446 / FRS / GMRS (446 / 462–467), and some commercial UHF.
它听不到什么What it cannot hear
- 调频广播 FM（76–108 MHz）：频率太低，UV-5R 收不到。
- 中波 AM 广播：不在其接收范围内。
- 手机蜂窝：频段/制式不覆盖，且接收受限。
- 大多数数字集群/加密：即使频率落在范围内，UV-5R 是模拟 FM 机，解不出数字/加密（如 TETRA、P25 数字部分、DMR 时隙需另类设备）。
想听短波/航空全段，UV-5R 力不从心，需另配宽带接收机或 SDR。
- FM broadcast (76–108 MHz): too low in frequency for the UV-5R.
- AM medium-wave broadcast: outside its receive range.
- Cellular: band/mode not covered, and reception is restricted.
- Most digital trunking / encrypted: even if the frequency is in range, the UV-5R is an analogue FM radio and cannot decode digital/encrypted (e.g. TETRA, P25 digital, DMR time-slots need other gear).
For shortwave or full aviation coverage, the UV-5R falls short — use a wideband receiver or SDR instead.
扩展接收（含航空 AM）Extending receive (incl. aviation AM)
部分 UV-5R 在 VHF 低端只到 136 MHz，听不到航空频段（108–137 MHz，AM）。可通过 CHIRP 修改"Receiver Limit"字段 或机型菜单把 VHF 下限下探到 100/108 MHz，从而收听航空 AM；UHF 上限也可拓到 520。操作后镜像、灵敏度下降会明显，属正常权衡。
Some UV-5R units start VHF at 136 MHz and cannot reach aviation (108–137 MHz, AM). You can lower the VHF floor to ~100/108 MHz via CHIRP's "Receiver Limit" field or the radio menu, so you can listen to aviation AM; the UHF ceiling can also be pushed to 520. After doing so images and sensitivity drop noticeably — a normal trade-off.
能合法监听什么What you can lawfully listen to
- 业余中继/直频：你的本行，随意。
- 气象 NOAA WX：162 MHz，免费天气，纯接收。
- 航空（若开启）：塔台/航班通话，爱好者常见监听对象。
- 海事 VHF：港口/船舶通信。
- PMR/FRS/GMRS 等：很多地区允许接收民用对讲，但部分地区对监听有规定，先了解本地法规。
- Amateur repeaters / simplex: your home turf, free to monitor.
- NOAA WX weather: 162 MHz, free weather, receive-only.
- Aviation (if enabled): tower/aircraft chatter, a popular hobby target.
- Marine VHF: port / ship communications.
- PMR / FRS / GMRS etc.: receive-only of civilian walkie-talkies is allowed in many areas, but some regions restrict monitoring — check local rules first.
接收机的短板The receiver's weak spots
- 选择性一般：强信号附近容易被邻频"带走"或串扰。
- 前端过载：城市/基站密集处易饱和，近处强台压住远处弱台。
- 镜像/假响应：便宜射频前端的通病，扩展频段后更明显。
- 灵敏度有限：比专业接收机弱，弱信号需外接天线。
- Modest selectivity: near a strong signal it is easily pulled or intermodulated.
- Front-end overload: in dense city/base-station areas it saturates, strong local stations blanking weak distant ones.
- Images / spurious responses: a known trait of cheap RF front-ends, worse after extending the range.
- Limited sensitivity: weaker than a pro receiver; weak signals need an external antenna.

UV-5R CTCSS / DCS 亚音设置UV-5R CTCSS / DCS Tones
搞懂亚音，才能稳定打开中继、避免"只听不说"。Understand tones to reliably open repeaters and avoid "hear but not heard".
什么是亚音What are sub-audible tones
CTCSS（连续音频编码静噪）是模拟亚音，让中继/群组只在收到特定低频音调时才打开静噪；DCS 是数字亚音（代码）。作用：减少干扰、让中继只响应授权用户。
CTCSS (Continuous Tone-Coded Squelch System) is an analogue sub-tone that opens squelch only when a specific low tone is present; DCS is the digital version (code). They reduce interference and let a repeater respond only to authorised users.
设置发射亚音（最常用）Set the transmit tone (most common)
设置接收亚音Set the receive tone
MENU 11 MENU 选 R-CTCS。注意：仅当你只想听带该亚音的信号时才开；日常用中继一般只设发射亚音，接收亚音留 OFF，否则会"听不到别人"。
MENU 11 MENU choose R-CTCS. Note: only enable it when you want to hear only signals carrying that tone. For everyday repeater use, set the transmit tone only and leave receive OFF — otherwise you'll "not hear others".
DCS 数字亚音DCS digital tone
菜单 12 T-DCS（发射）/ 10 R-DCS（接收）。DCS 用 3 位代码（如 023、754）。与 CTCSS 二选一，按中继要求设置。
Menu 12 T-DCS (transmit) / 10 R-DCS (receive). DCS uses a 3-digit code (e.g. 023, 754). Pick CTCSS or DCS per the repeater's requirement.

UV-5R 中继（Repeater）设置UV-5R Repeater Setup
两种方法把本地中继写进 UV-5R，并避开最常见的"只听不说"。Get your local repeater into the UV-5R and avoid the classic "hear but not heard".
中继原理How a repeater works
中继台用两个频率：下行（你听）与上行（你发），两者之差叫频差（Offset）。你发到上行，中继收到后从下行重发，从而扩大覆盖。
A repeater uses two frequencies: the downlink (what you hear) and the uplink (what you transmit). The gap is the Offset. You send to the uplink; the repeater retransmits on the downlink, extending coverage.
方法一：分别存 RX/TX（推荐）Method 1: store RX/TX separately (recommended)
方法二：用 SFT-D + OFFSETMethod 2: SFT-D + OFFSET
检查与常见错误Check & common mistakes
- 只听不说：多半发射哑音（T-CTCS / Tone）未设或错 → 中继不转发。
- 完全静音：接收哑音（R-CTCS）误开，清掉即可。
- 频差方向反了：+/− 与中继表不一致，对调即可。
- Hear but not heard: missing/wrong transmit tone (T-CTCS / Tone) → repeater ignores you.
- Dead silence: receive tone (R-CTCS) accidentally on — clear it.
- Offset reversed: +/− mismatched the listing — swap it.

UV-5R 故障排查UV-5R Troubleshooting
把"能收不能发""突然没声"等高频问题一次讲清。Fix the high-frequency problems — "receive OK, can't transmit", sudden silence, and more.
能收不能发（只听不说）Receive OK, can't transmit (hear but not heard)
原因：发射亚音（CTCSS/Tone）缺失或错误，中继不转发。
解决：按中继表设菜单13 T-CTCS（或 CHIRP Tone Mode=Tone），核对频差方向（菜单25）。
Cause: missing or wrong transmit tone (CTCSS/Tone) — the repeater ignores you.
Fix: set Menu 13 T-CTCS per the repeater listing (or CHIRP Tone Mode=Tone); check offset direction (Menu 25).
开机后完全没声音Dead silence after power-on
原因：接收亚音（R-CTCS）误开，机器只接收带该亚音的信号。
解决：菜单11 将 R-CTCS 设回 OFF（或 TSQL 改成与发射一致）。
Cause: receive tone (R-CTCS) left on, so the radio only opens for that tone.
Fix: Menu 11, set R-CTCS back to OFF (or match TSQL to your transmit tone).
距离近、断续Short range / choppy
天线未拧紧或接触不良；空载波发射会烧功放——务必先装天线再发射。静噪（菜单0 SQL）过高也会滤掉弱信号。
Antenna loose or poor contact; transmitting with no antenna can burn the PA — always fit the antenna before TX. Squelch (Menu 0 SQL) set too high also blocks weak signals.
输不进精确频率Can't enter the exact frequency
把菜单1 STEP 设为 5.00 kHz（或 2.5K 用于7位频率）。仍在信道模式时按 VFO/MR 切到频率模式。
Set Menu 1 STEP to 5.00 kHz (or 2.5K for 7-digit frequencies). If stuck in channel mode, press VFO/MR to Frequency Mode.
还是不行？恢复出厂Still stuck? Factory reset

预防小贴士Prevention tips
- 首次写频前先导出原机配置备份（见 CHIRP 写频页）。
- 用原厂座充与电池，触点定期清洁。
- 远离强基站环境，必要时外接好天线。
- 勿擅自解锁发射范围，跨段发射违法且易坏机。
- Before first programming, export and back up the radio's config (see the CHIRP page).
- Use the original charger and battery; clean contacts periodically.
- Stay clear of strong base-station environments; use a good external antenna when needed.
- Do not unlock TX range — cross-band transmit is illegal and can damage the radio.
