前面板按键与旋钮详解

Front Panel Controls & Switches

本章要点:FTX-1 系列的操控面板全部集中在 FTX-1 Field 便携控制头上——一块 TFT 显示屏、两个调谐旋钮、两个 AF/RF/SQL 旋钮、一排顶部功能键与一排屏幕软键。本章先用实拍图建立“位置感”,再给出整机控件位号总览表,最后逐个控件讲清“旋转做什么、短按做什么、长按做什么、换模式后功能怎么变”。读完本章,你可以不看菜单就能完成 90% 的日常操作。

6.1 前面板全貌Front Panel Overview

FTX-1 Field 前面板全貌
图 6-1 FTX-1 Field 前面板全貌Fig. 6-1 FTX-1 Field front panel
EN

The front panel of the FTX-1 Field is organized into three vertical zones and two horizontal rows. Left zone: the SUB-side controls. Right zone: the MAIN-side controls, including the large main tuning dial. Bottom row: the six on-screen soft keys that belong to the spectrum scope. A single row of keys runs along the top edge for GM, S-DX, PMG, MAG, N/W, SPLIT, V/M and M-V.

FTX-1 Field 的前面板可归纳为“三个纵向区、两条横向排”。左区是 SUB 侧控件,右区是 MAIN 侧控件(含大直径主调谐旋钮),最下方一行是与频谱相关的 6 个屏幕软键;顶边一行则集中了 GM、S-DX、PMG、MAG、N/W、SPLIT、V/M 与 M-V 等功能键。

图 6-2 左侧视角(SUB 侧旋钮区)Fig. 6-2 Left-side view
FTX-1 Field 右侧视角
图 6-3 右侧视角(FUNC / 主旋钮区)Fig. 6-3 Right-side view

EN

Both side views show that every control carries its name printed directly on the chassis, and several keys carry a small boxed second-function label printed next to the primary name — for example MAG with a boxed [BAND], N/W with a boxed [MODE], and both AF/RF/SQL knobs with a boxed [DSP]. Learn to read these printed boxes first: they tell you what a press-and-hold will do before you enter any menu.

两张侧视图可以确认:每个控件旁都直接印有名称,部分按键还在主名称旁另印了一个白底方框的第二功能标识——例如 MAG 旁的 [BAND] 方框、N/W 旁的 [MODE] 方框,以及两个 AF/RF/SQL 旋钮旁的 [DSP] 方框。先学会读这些丝印方框:它们在进入任何菜单之前就能告诉你“长按会做什么”。

注意NOTE
面板丝印是硬件版本的一部分,不同批次可能出现不同的第二功能方框文字。若你的机器上方框文字与本书表格不一致,请以实机丝印与原厂说明书的对应章节为准。
The silkscreen is part of the hardware revision. If the boxed second-function text on your unit differs from the table here, follow the silkscreen on your own radio and the corresponding section of the original manual.

Table 6-1 lists only what is silkscreened in Figs. 6-1 to 6-3. The six soft keys under the display belong to the spectrum screen; their behaviour in each screen is covered in Chapters 8 and 9.

6.3 左侧旋钮区(SUB 侧)Left Zone — SUB-side Controls

SUB DIALSUB 侧调谐旋钮
旋转:调谐 SUB 侧频率。短按:把 MAIN 侧与 SUB 侧互换(屏幕显示随之左右调换)。Rotate to tune the frequency of the SUB-side. Each press swaps the MAIN-side and the SUB-side.

ON/OFF (LOCK) Switch电源 / 锁定键
长按约 1 秒:开机或关机。开机状态下短按:开启或解除 MAIN DIAL / SUB DIAL 的锁定。Press and hold for one second to turn the transceiver ON or OFF. When the power is ON, press this switch briefly to engage or release the DIAL or SUB DIAL lock.

AF/RF/SQL-SUBSUB 侧音量 / RF 增益 / 静噪旋钮
旋转(默认):调整 SUB 侧音量(AF)。按下后:旋钮功能随工作模式变化——FM/AM 族为静噪(SQL)电平,SSB/CW 族为 RF 增益。旋钮上方印有 [DSP] 方框第二功能丝印。Rotate (default) to adjust the SUB-side audio volume. Its function after a press depends on the operating mode — SQL level in FM/AM family modes, RF gain in SSB/CW family modes. A boxed [DSP] second-function label is printed above the knob.

EN

The LED beside the power switch reports the power and charging state. The LED glows blue when the transceiver power is ON, whether the transceiver is still charging or fully charged. When the transceiver is powered OFF, the LED glows red while charging, turns green when charging is complete, and blinks red and green in case of a charging error.

电源键旁的 LED 用于指示开机与充电状态:整机开机时 LED 亮蓝色,无论电池正在充电还是已经充满;整机关机时,充电中 LED 亮红色,充电完成后转为绿色,出现充电异常时则红色与绿色交替闪烁。

HAM 实战 · 技术提示FIELD NOTE
新手最快的“出声音”路径:① 长按电源键约 1 秒开机;② 确认屏幕左下角的调谐锁定标记未出现——若屏上显示 LOCK,短按电源键解除;③ 把 MAIN 侧 AF/RF/SQL 旋钮顺时针拧到约 1/3 行程(默认它是音量 AF);④ 天线接好后把 SQUELCH/RF 项调到能听见背景噪声的位置。整条路径不需要进入任何菜单。(社区经验)
Fastest way to get audio out of the box: 1) hold the power key for about one second; 2) make sure “LOCK” is not shown on the display — if it is, tap the power key to release it; 3) turn the MAIN-side AF/RF/SQL knob clockwise to about one third of its travel (by default it is the audio volume); 4) with an antenna connected, set the squelch/RF item so that you can hear background noise. No menu entry is needed. (community-reported)

6.4 右侧旋钮与主调谐区(MAIN 侧)Right Zone — MAIN-side Controls and Main Dial

MAIN DIALMAIN 侧主调谐旋钮
旋转:调谐 MAIN 侧频率,步进量取决于工作模式(默认值见表 6-2)。Tune the frequency of the MAIN-side. The amount of frequency change depends on the operation mode (default setting: see Table 6-2).

FUNC Knob功能旋钮
旋转:调整当前选定的功能,无需进入菜单。短按:确认并返回操作画面。长按:打开功能选择画面以更改 [FUNC] 旋钮所分配的功能。Rotate to change the currently selected function without entering the menu. Press to confirm and return. Press and hold to open the function selection screen and re-assign the [FUNC] knob.

AF/RF/SQL-MAINMAIN 侧音量 / RF 增益 / 静噪旋钮
旋转(默认):调整 MAIN 侧音量(AF)。按下后:FM/AM 族模式为静噪电平,SSB/CW 族模式为 RF 增益。旋钮上方印有 MAIN 与 [DSP] 方框第二功能丝印。Rotate (default) for the MAIN-side audio volume. After a press it becomes the squelch level in the FM/AM family and the RF gain in the SSB/CW family. “MAIN” and a boxed [DSP] label are printed above the knob.

QMB快速存储键
短按:调出 QMB 频道,屏幕上 “VFO” 或存储频道号会被 “QMB” 取代;连续短按可在各 QMB 频道间步进。长按:把当前 VFO 内容写入可用的 QMB 存储,蜂鸣声确认写入完成。按下 [V/M] 键可回到 VFO 模式。Press to recall a QMB channel — the “VFO” or memory channel number is replaced by “QMB”; press repeatedly to step through the QMB channels. Press and hold to write the current VFO contents to the available QMB memory, confirmed by a beep. Press [V/M] to return to VFO mode.

CLAR清晰度(Clarifier)键
短按:每按一次屏幕依次以红色显示 “CLAR RX” → “CLAR TX” → “CLAR RXTX” 并启用清晰度调节。长按:把已设置的清晰度偏移量一次性清零。Each press cycles the display through “CLAR RX” → “CLAR TX” → “CLAR RXTX” in red and activates the clarifier. Press and hold to clear the programmed offset altogether and reset it to zero.

DISP显示切换键
短按:依次切换操作画面。长按:关闭显示屏;触摸屏幕或对 FTX-1 做任何操作,画面即重新出现。Press to switch the Operation screen each time. Press and hold to turn off the display; the screen reappears when you touch the screen or perform any other operation on the FTX-1.

BACK返回键
短按:返回上一画面。长按:在设置 DSP 干扰抑制功能(SHIFT、WIDTH、NOTCH、CONTOUR、APF)时,把该设置恢复为默认值。Press to return to the previous screen. Press and hold while setting the DSP interference removal functions (SHIFT, WIDTH, NOTCH, CONTOUR, APF) to return that setting to its default value.

FINE/FAST微调 / 快速调谐键
短按:进入 FINE 微调(LSB/USB/CW/DATA/RTTY/PSK 为 1 Hz,AM/FM 族为 10 Hz),屏上 “FINE” 指示点亮;再按一次恢复原步进。长按:进入 FAST 快速调谐(10 倍步进),屏上 “FAST” 指示点亮;再按一次恢复原步进。Press for FINE tuning (1 Hz in LSB/USB/CW/DATA/RTTY/PSK, 10 Hz in the AM/FM family) — the “FINE” indicator lights. Press again to return to the original step. Press and hold for FAST tuning (10 times the step) — the “FAST” indicator lights; press again to return.

表 6-2 主调谐旋钮的默认步进Table 6-2 MAIN DIAL default tuning step
工作模式Operating Mode 默认步进1 Step
LSB / USB, CW-L / CW-U, DATA-L / DATA-U, RTTY-L / RTTY-U, PSK 20 Hz / [1 Hz] / (200 Hz)
AM / AM-N, FM / FM-N / C4FM, DATA-FM / D-FM-N 100 Hz / [10 Hz] / (1 kHz)

表中 [ ] 内为 FINE 微调时的步进,( ) 内为 FAST 快速调谐时的步进,其余为默认步进。

注意NOTE
原厂步进表中另列有一组 “10Hz / [1Hz] / (100Hz)” 数值;受页面版式影响,该组数值对应的模式分组在本页提取文本中顺序不明,故本书未将其并入表 6-2,请以原厂说明书原表为准校对。
The original step table also lists a third set of values, “10Hz / [1Hz] / (100Hz)”. Because of the page layout, the mode grouping for that set cannot be determined from the extracted text, so it has been left out of Table 6-2; verify against the original table in the manual.
避坑指南PITFALL
最常见的“机器坏了”错觉:短按或长按过 [FINE/FAST] 后忘记按回。此时旋转主调谐旋钮,频率变化会变成原来的 1 Hz 或 10 倍,用户会以为旋钮失灵。看到屏上出现 “FINE” 或 “FAST” 字样,再按一次 [FINE/FAST] 即可恢复。
The classic false alarm: after tapping or holding [FINE/FAST] and forgetting to return, the dial appears to behave wrongly — 1 Hz or ten times the step. If “FINE” or “FAST” is shown on the display, press [FINE/FAST] once more to restore the original step.
EN

The BUSY/TX indicator sits between [QMB] and [CLAR], above the main dial, and is marked “BUSY/TX SUB MAIN”. This indicator glows green (blue in C4FM) when the squelch opens, and glows red during transmit. Note that it glows green only when the [AF/RF/SQL] knob is set to “SQL” or “AUTO”.

BUSY/TX 指示窗位于 [QMB] 与 [CLAR] 之间、主调谐旋钮上方,丝印为 “BUSY/TX SUB MAIN”。静噪打开时该指示亮绿色(C4FM 下为蓝色),发射时亮红色。需要注意:只有当 [AF/RF/SQL] 旋钮被设为 “SQL” 或 “AUTO” 时,它才会亮绿色。

6.5 顶部功能键排Top-edge Function Keys

GM组监听功能键
开启或关闭 GM(Group Monitor,组监听)功能。该功能的详细说明请查阅可从 Yaesu 官网下载的 GM Function Instruction Manual。Turns the GM (group monitor) function ON/OFF. For details refer to the GM Function Instruction Manual, downloadable from the Yaesu website.

S-DX超级 DX 键
短按:启用 Super DX 功能以提高接收灵敏度。长按:把 TFT 屏幕上的画面保存到 microSD 卡。Press to enable the Super DX function and increase sensitivity. Press and hold to save the TFT screen image to the microSD card.

PMG主存储组键
短按:显示 PMG(Primary Memory Group,主存储组)。长按:把当前显示的频率登记到 PMG。Press to display the PMG (Primary Memory Group). Press and hold to register the displayed frequency in the PMG.

MAG存储频道频段自动分组键
VFO 模式下:每按一次切换工作频段;长按则显示工作频段选择画面,触摸目标频段即可,触摸后约 1 秒确认并返回操作画面。存储(Memory)模式下:每按一次,自动成组调出同一频段的存储频道。In VFO mode each press switches the operating frequency band; press and hold to open the band selection screen and touch the desired band — it is confirmed in about one second and the radio returns to the operating screen. In Memory mode each press recalls only memory channels of the same frequency band as a group.

N/W窄带 / 工作模式键
短按:把 DSP(数字)中频滤波器设为窄带宽。长按:切换工作模式,屏幕出现模式选择画面后触摸目标模式;触摸 [PRESET] 可显示适用于 FT8 操作的设置。Press to set the DSP (digital) IF filters to Narrow bandwidth. Press and hold to switch the operating mode: the mode selection screen appears, touch the desired mode. Touch [PRESET] to display the settings that apply to FT8 operation.

SPLIT异频收发键
利用 MAIN 侧与 SUB 侧两个频率寄存器实现异频(Split)收发。这使得 FTX-1 特别适合参与高强度的 DX-pedition 联络。Split-frequency operation using the MAIN-side and SUB-side frequency registers. This makes the FTX-1 especially useful for high-level DX-peditions.

V/MVFO / 存储切换键
短按:在 VFO 与存储系统之间切换频率控制。长按:显示存储频道列表,从列表中触摸选择目标存储频道。Press to toggle frequency control between VFO and the memory system. Press and hold to display the memory channel list, then touch and select the desired channel.

M►V存储转 VFO 键
短按:把存储频道中保存的数据转移到 VFO。长按:进入 Memory Tune 模式,可像 VFO 一样从任意存储频道上自由调谐;只要不覆写当前存储内容,Memory Tune 不会改变该存储频道的数据,此时屏幕以 “MT” 取代 “M-nnn”。按下 [V/M] 键可回到该存储频道原本保存的频率。Press to transfer data saved in a memory channel to the VFO. Press and hold to tune freely off any memory channel in Memory Tune mode, similar to VFO operation; as long as you do not overwrite the memory, its contents are not altered, and “MT” appears instead of “M-nnn”. Press [V/M] to return to the originally memorised frequency of that channel.

HAM 实战 · 技术提示FIELD NOTE
把 [V/M] 长按当作“存储频道浏览器”用:一次列出全部存储频道,触摸即调出,比用旋钮逐个翻快得多。发现常用台想临时换到 VFO 微调时,用 [M►V] 长按进入 MT 模式调,调歪了直接按 [V/M] 回到原频率,存储不会被破坏。追台(DX 追逐)时最省心的顺序是:VFO 上调好发射频率 → [V/M] 存台 → 用 [SPLIT] 开异频。(社区经验)
Treat a press-and-hold of [V/M] as a memory-channel browser: the whole list appears at once and a touch recalls a channel — far faster than stepping with the dial. If you want to tune off a channel temporarily, hold [M►V] to enter MT mode; press [V/M] to snap back to the stored frequency without damaging the memory. For DX chasing the tidiest sequence is: set the transmit frequency in VFO, store it with [V/M], then enable split with [SPLIT]. (community-reported)

6.6 屏幕下方软键区与指示灯Bottom Soft Keys and Indicators

EN

Along the bottom edge of the TFT screen there are six touch soft keys: CENTER, 3DSS, MULTI, SCOPE, SPAN and SPEED. They belong to the spectrum scope screen. Above them, the frequency axis of the scope is drawn, e.g. -40k / -20k / 14.195.000 / +20k / +40k in the dual band (Left/Right) screen.

TFT 屏幕下沿有 6 个触摸软键:CENTER、3DSS、MULTI、SCOPE、SPAN 与 SPEED,它们属于频谱显示画面。软键上方是频谱的频率轴,例如在 Dual band(左右)画面中显示为 -40k / -20k / 14.195.000 / +20k / +40k。

CENTER / 3DSS / MULTI / SCOPE / SPAN / SPEED屏幕软键区(触摸)
触摸任一软键即切换对应的频谱显示方式或参数。SPAN 决定显示范围(屏幕上以 SPAN nnnkHz 显示跨度),SPEED 决定扫描速度,CENTER 让接收频率固定在屏幕与频谱的中心;STOP(速度选项之一)用于暂时保持 3DSS 显示与瀑布显示的动作。Touch any of these keys to switch the corresponding scope display or parameter: SPAN sets the display range (shown as SPAN nnnkHz), SPEED sets the sweep speed, CENTER keeps the receive frequency at the centre of the screen and spectrum display, and STOP holds the 3DSS and waterfall displays temporarily.

EN

The VFO mode indicator shows the operating status of the frequency register at a glance. In the factory default, blue means operation on VFO mode, green means operation on Memory mode, and red means Clarifier operation. In the photograph of Fig. 6-1 the two boxes beside the SUB and MAIN frequency readouts read “VFO” in blue, which confirms VFO-mode operation on both sides.

VFO 模式指示用于一眼看清频率寄存器的工作状态。出厂默认:蓝色表示工作在 VFO 模式,绿色表示工作在存储(Memory)模式,红色表示 Clarifier 正在工作。在图 6-1 的实拍画面中,SUB 与 MAIN 频率显示旁的方框均以蓝色显示 “VFO”,说明两侧都在 VFO 模式。

避坑指南PITFALL
不要为了“让屏幕上有一个好看的频谱”而去反复按 [DISP]:短按 [DISP] 会依次切换三种不同的屏幕布局(Dual band 左右 / Dual band 上下 / Single band),界面变化很大,容易让人误以为机器被重置。长按 [DISP] 才是关屏;关屏后触摸屏幕或操作任一键即可恢复。
Do not keep tapping [DISP] just to make the scope look right: each short press cycles through the three screen layouts (Dual band Left/Right, Dual band Up/Down, Single band), which looks like a different radio. Only a press-and-hold turns the display off, and any touch or key restores it.

6.7 [AF/RF/SQL] 旋钮的模式差异(重点)Key Difference of the [AF/RF/SQL] Knobs

两个 [AF/RF/SQL] 旋钮默认都只做音量(AF)。按下之后它变成什么,取决于当前工作模式——这是 FTX-1 最容易搞混、也最影响“收得到 / 收不到”的一处设计。

表 6-3 按下 [AF/RF/SQL] 旋钮后的功能(按工作模式)Table 6-3 Function of a pressed [AF/RF/SQL] knob, by operating mode
工作模式Operating Mode 旋钮功能Knob function
AM / AM-N / FM / FM-N / C4FM / D-FM / D-FM-N / VW SQL 静噪电平调节
LSB / USB / CW-L / CW-U / DATA-L / DATA-U / RTTY-L / RTTY-U / PSK RF 增益调节
避坑指南PITFALL
同一个旋钮,在 SSB / CW 模式下是 RF 增益,在 FM / AM 模式下是 SQL 静噪——这是全机最重要的差异,务必记牢。后果很具体:在 SSB 下把 RF 增益当作“音量”往左拧,接收灵敏度会整体下降,弱信号直接消失,用户会以为天馈或传播出了问题;反过来在 FM 下把静噪往右拧太多,微弱的中继信号会被静噪直接切掉,同样听不到声音。RF 增益的正常位置是顺时针拧到底。
One knob, two meanings: RF gain in SSB/CW, squelch level in FM/AM. The consequences are concrete. In SSB, turning the “volume” down actually reduces receiver gain, so weak signals vanish and you will blame the antenna or the propagation. In FM, turning the squelch too far clockwise cuts off weak repeater signals entirely. The normal position of the RF gain is fully clockwise.

6.7.1 RF 增益的作用What the RF Gain Does

EN

The RF Gain control provides manual adjustment of the gain levels for the receiver RF and IF stages, to account for noise and signal strength conditions at the moment. The [AF/RF/SQL] knob is normally in the fully clockwise position. It does not operate in FM/FM-N/DATA-FM and D-FM-N mode.

RF 增益控制用于手动调节接收机 RF 与 IF 级的增益,以适应当前的噪声与信号强度条件。[AF/RF/SQL] 旋钮通常应置于顺时针到底的位置。在 FM/FM-N/DATA-FM 与 D-FM-N 模式下,该功能不起作用。

6.7.2 静噪(SQL)的作用What the Squelch Does

EN

The squelch system allows the background noise to be muted when no signal is being received. Normally, the squelch is not used during SSB or CW operation. Rotate the [AF/RF/SQL] knob to adjust the squelch until the noise disappears. If the squelch knob is turned too far to the right, weak signals cannot be heard.

静噪系统用于在没有收到信号时抑制背景噪声。SSB 或 CW 操作时通常不使用静噪。旋转 [AF/RF/SQL] 旋钮调整静噪,直到噪声消失为止;如果把静噪旋钮向右拧得过多,弱信号就无法听到了。

6.7.3 改变 [AF/RF/SQL] 旋钮的行为Switching the Operation of the [AF/RF/SQL] Knob

EN

  1. Press and hold the [FUNC] knob.
  2. Select [OPERATION SETTING] → [GENERAL] → [RF/SQL VR].

Press the [FUNC] knob, or wait for about 3 seconds, to save the setting. Touch [BACK] several times to return to normal operation.

按 [FUNC] 旋钮,或等待约 3 秒,即可保存设置。多次触摸 [BACK] 返回正常工作画面。

技术提示TIP
把 RF/SQL VR 设为 “AUTO”,日常通联基本不用再管这个开关:FM 中继台自动给你静噪,SSB/CW 自动给你 RF 增益。只有做弱信号弱化噪声的精细接收(例如 CW 弱信号堆叠)时,才临时切到 “RF” 手动收窄增益。(社区经验)
Set RF/SQL VR to “AUTO” and you can largely forget this switch day to day: FM repeaters give you squelch, SSB/CW gives you RF gain. Only switch to “RF” temporarily when you need to back the gain off manually for weak-signal work, such as digging CW signals out of a pile-up. (community-reported)

夜间或在野外用 FTX-1 Field 时,把 VFO 指示与屏幕亮度一起压暗,能明显降低屏幕对眼睛的刺激,也省电。关屏更彻底:长按 [DISP],需要看频率时触摸一下屏幕即可短暂显示。收听为主、按键很少的场景(守听中继、等 DX 窗口)这样用最舒服。(社区经验)
At night or in the field, dim both the indicator colours and the TFT brightness — it is much easier on the eyes and saves battery. For the most frugal setup, press and hold [DISP] and simply touch the screen when you need to read the frequency. This suits listening-only sessions such as holding on a repeater or waiting for a DX window. (community-reported)

6.8 支架螺孔与安装Bracket Screw Hole and Mounting

optima 主机的 [DC 13.8V] 不是“随便找个电源就能用”:原厂要求电源能提供至少 25 A @13.8 VDC。用常见的 5 A 小开关电源会在大功率发射瞬间电压塌陷,表现为功率上不去、屏幕闪、甚至重启。野外用电池时同样要确认电池与线径能承受峰值电流。
The [DC 13.8V] input on the optima main body is not a “any PSU will do” input: the manual requires a supply capable of at least 25 A @13.8 VDC. A small 5 A switching supply will sag on transmit peaks — power output drops, the screen flickers, or the radio restarts. The same applies to field batteries: make sure the battery and wiring can take the peak current.
技术提示TIP
Field 头的 USB Type-C 口是野外最实用的一个口:接一个 45 W 以上、支持 DC 15 V 2 A 输出的 USB PD 充电器就能给机内 SBR-52LI 锂电池充电,同一根线接电脑还能走 CAT 遥控。出发前把充电宝的 PD 档位确认清楚(必须是 15 V 2 A 档),否则充不进电。(社区经验)
The USB Type-C port on the Field head is the most useful port in the field: a USB PD charger rated 45 W or more and compatible with DC 15 V 2 A output will charge the internal SBR-52LI pack, and the same cable to a computer gives you CAT control. Check the PD profile of your power bank before you leave — 15 V 2 A is required, otherwise charging will not start. (community-reported)

To prevent damage from lightning, atmospheric electrical discharges, electric shock etc., provide a good earth ground. Use a short, thick, braided cable to connect the station equipment to the buried ground rod (or alternative earth ground system).

为防止雷击、大气放电、触电等造成损坏,必须设置良好的大地接地。请使用短而粗的编织线,把电台设备连接到埋地接地棒(或其他接地系统)。

注意NOTE
FTX-1 Field 与 optima 主机各自都有 GND 端子。使用分体配置时,两台设备的接地应汇接到同一接地点,避免形成接地回路。
Both the FTX-1 Field and the optima main body provide their own GND terminal. When used as separate units, bond both to the same earth point to avoid a ground loop.
HAM 实战 · 技术提示FIELD NOTE
接了外接线性放大器或 FC-40 天调时,最容易被忽略的是“信号地”:Field 头的 [EXT SPKR] 插座带 SIGNAL GND,接外部设备时把这根地线一起接好,可以明显降低射频反馈引起的啸叫与键控乱跳。(社区经验)
When you connect a linear amplifier or an FC-40 tuner, the signal ground is the item most often forgotten: the [EXT SPKR] jack on the Field head carries SIGNAL GND, and bonding that line to the external equipment noticeably reduces RF-feedback howl and erratic keying. (community-reported)

显示屏指示详解

Display Indications

本章要点:FTX-1 的 TFT 屏幕一共有三种布局:Dual band(左右)、Dual band(上下)与 Single band,由 [DISP] 键循环切换。本章先给出三种布局的示意与切换关系,再把屏幕上出现的每一个元素——MAIN VFO / SUB VFO 指示、RX、RTTX、S 表、PO 表、VOL、MODE、FILTER 通带框、CENTER FAST2 SPAN 等——逐项对照解释,让你看一眼屏幕就知道机器现在处于什么状态。

8.1 屏幕布局与画面切换Screen Layout and Screen Switching

EN

Each time you press the [DISP] key, the screen display will change as follows. You can also press and hold the [DISP] key to temporarily turn off the screen display. The screen will reappear when you perform any FTX-1 operation, such as touching the screen.

每按一次 [DISP] 键,屏幕显示都会按下列顺序切换。也可以长按 [DISP] 键暂时关闭屏幕显示;只要对 FTX-1 进行任何操作(例如触摸屏幕),画面就会重新出现。

表 8-1 三种屏幕布局Table 8-1 The three screen layouts
布局Layout 显示内容Contents
Dual band screen (Left/Right) MAIN 与 SUB 频率左右并列显示,屏幕下方为频谱画面,可直观观察频段状况的变化。
Dual band screen (Up/Down) MAIN 与 SUB 频率上下排列的双频显示画面。
Single band screen 只显示 MAIN 或 SUB 其中一侧频率的单频画面;每按一次 [SUB DIAL] 旋钮在 MAIN 与 SUB 之间切换。

8.2 Dual band 画面(左右布局)Dual band Screen (Left/Right)

EN

This is a dual band screen that displays the MAIN and SUB frequencies on the left and right. The scope screen allows you to intuitively visualize changes in the band condition. The scope screen settings show the mode, the sweep speed and the span width.

这是把 MAIN 与 SUB 频率分列左右的双频画面。屏幕下方的频谱画面可以让你直观地看到频段状况的变化;频谱画面的设置项则显示模式(如 CENTER)、扫描速度(如 FAST2)与跨度宽度(如 SPAN 100kHz)。

下面用表格模拟图 6-1 实拍画面中 Dual band(左右)布局的各区域位置。左侧一列为 SUB 侧信息,右侧一列为 MAIN 侧信息,横贯项表示该区域跨越左右两半屏。

注意NOTE
表 8-2 的数值来自图 6-1 的实拍画面(SUB 侧 432.500.000、MAIN 侧 14.195.000),仅用于说明各元素的位置关系;你机器上显示的实际频率会随调谐而变化。频谱显示区左下角的 MAIN 标注说明该频谱画面属于 MAIN 侧。
The values in the layout above come from the photograph in Fig. 6-1 (432.500.000 on the SUB side, 14.195.000 on the MAIN side) and only illustrate where each element sits; your radio will show whatever frequency you tune to. The MAIN label at the lower-left of the scope area indicates that the scope belongs to the MAIN side.

8.3 Dual band 画面(上下布局)Dual band Screen (Up/Down)

EN

This is the screen for dual band operation, where the MAIN and SUB frequencies are displayed above and below. The upper half carries the MAIN side, and the lower half carries the SUB side; each half also shows the important receiver settings for that side.

这是双频操作的上下布局画面,MAIN 与 SUB 频率以上下方式排列:上半屏为 MAIN 侧,下半屏为 SUB 侧;每一侧还各自显示该侧的重要接收机设置(Important Receiver Settings)。

表 8-3 Dual band(上下)布局区域示意Table 8-3 Dual band (Up/Down) layout map
画面区域 内容
上半屏 MAIN 侧:MAIN 频率显示、MAIN 侧重要接收机设置(Important Receiver Settings for MAIN side)
下半屏 SUB 侧:SUB 频率显示、SUB 侧重要接收机设置(Important Receiver Settings for SUB side)
切换方式 由 [DISP] 键循环切换至本布局
EN

Compared with the Left/Right layout, the Up/Down layout gives each band a wider horizontal strip for its frequency readout and its important receiver settings, at the cost of the side-by-side scope view.

与左右布局相比,上下布局为每个频段提供了更宽的一条横向区域,用于频率读数与重要接收机设置;代价是不再有左右并排的频谱视图。

8.4 Single band 画面Single band Screen

EN

This is the screen for single band operation, where only the MAIN or SUB frequency is displayed. Each time you press the SUB DIAL knob, it switches between MAIN and SUB.

这是单频操作画面,只显示 MAIN 或 SUB 其中一侧的频率。每按一次 [SUB DIAL] 旋钮,就在 MAIN 与 SUB 之间切换。

切换方式 由 [DISP] 键切换至本布局;在本布局下每按一次 [SUB DIAL] 旋钮,在 MAIN 与 SUB 之间切换
HAM 实战 · 技术提示FIELD NOTE
Single band 画面最适合“盯一个频段”的场景:守候一个 DX 窗口、参与一次夜间 80 米网络,或者做 FT8。此时短按 [SUB DIAL] 可以瞬间把另一侧频率拉到眼前,比在两个并排的小字里找频率快得多。(社区经验)
The Single band screen is the best choice when you are watching one band: holding a DX window, checking into a 80 m net at night, or running FT8. A tap on [SUB DIAL] brings the other side’s frequency to the front instantly — far faster than reading two small readouts side by side. (community-reported)

MAIN / SUB 主侧 / 副侧标识 标明该半屏属于 MAIN 侧还是 SUB 侧。
VFO VFO 模式指示 频率寄存器的工作状态指示。出厂默认:蓝色为 VFO 模式,绿色为存储(Memory)模式,红色为 Clarifier 工作。颜色可在 [DISPLAY SETTING] → [VFO IND COLOR] 中更改。
RX 接收状态 该侧处于接收状态时显示(实拍画面为绿色底框)。
RTTX / CLAR RX / CLAR TX Clarifier 状态 每按一次 [CLAR] 键,屏幕以红色依次显示 “CLAR RX” → “CLAR TX” → “CLAR RXTX” 并启用清晰度调节;实拍画面中显示为 RXTX。

避坑指南PITFALL
看到屏幕上的 “RTTX” 不要以为是模式乱了:它是 Clarifier(清晰度)处于“接收与发射同时偏移”状态。这个状态由 [CLAR] 键循环产生,只要反复按 [CLAR] 直到屏上不再显示 Clarifier 状态即可关闭;长按 [CLAR] 则把偏移量直接清零。
Do not panic at “RTTX” on the display: it is the Clarifier offsetting both receive and transmit. It is produced by cycling the [CLAR] key — press [CLAR] repeatedly until the Clarifier status disappears to turn it off, or press and hold [CLAR] to reset the offset to zero.
HAM 实战 · 技术提示FIELD NOTE
把 S 表读数当成“天线系统的体检表”:在同一个频点上,如果 S 表读数突然比平时低 1~2 个 S 单位,先检查天线接头和馈线,而不是先怀疑传播——驻波或接头进水最常见。(社区经验)
Treat the S-meter reading as a health check for your antenna system: if it suddenly drops one or two S-units on a frequency you know well, inspect the connectors and feeder before blaming propagation — a poor SWR or water in a connector is the usual culprit. (community-reported)

9.1 频率显示Frequency Display

EN

The frequency display shows the transmit and receive frequencies. Simultaneous reception of HF/HF is not supported.

频率显示区显示发射频率与接收频率。本机不支持 HF/HF 同时接收。

避坑指南PITFALL
“HF/HF 同时接收不受支持”是硬性限制:MAIN 与 SUB 两侧不能同时都工作在 HF 频段收听。想一边听 40 米、一边听 20 米是做不到的,请把另一侧安排到 VHF/UHF 频段。这不是故障,不要反复恢复出厂设置。
“Simultaneous reception of HF/HF is not supported” is a hard limitation: the MAIN and SUB sides cannot both receive on HF at the same time. Listening on 40 m and 20 m simultaneously is not possible — put the other side on VHF/UHF instead. This is not a fault, so do not keep resetting the radio.

9.2 键盘输入频率Keyboard Frequency Entry

EN

  1. Touch the “Hz” area of the frequency display.
  2. Enter the frequency using the numeric keys.
  3. Touch [ENT] to confirm.
  1. 触摸频率显示区的 “Hz” 位置。
  2. 用数字键输入频率。

注意NOTE
在输入过程中如果 10 秒内没有任何操作,输入会被自动取消。
If there is no operation within 10 seconds during entry, the input will be cancelled.
EN

There is a short-cut for frequencies ending in zero: touch [ENT] after the last non-zero digit. For example, to enter 7.00.000 MHz, press [0] → [0] → [7] → [ENT], or simply [7] → [.] → [ENT]. To enter 7.03.000 MHz, press [7] → [.] → [0] → [3] → [ENT].

对于以零结尾的频率有一个快捷输入法:输完最后一位非零数字后直接触摸 [ENT]。例如要输入 7.00.000 MHz,可以按 [0] → [0] → [7] → [ENT],也可以直接按 [7] → [.] → [ENT];要输入 7.03.000 MHz,则按 [7] → [.] → [0] → [3] → [ENT]。

技术提示TIP
记住“小数点”这个偷懒技巧:输入 14.195 时只需按 [1][4][.][1][9][5][ENT],机器会自动补齐后面的零。比一位一位敲 9 个数字快一倍,在通联中临时 QSY 到某个具体频率时特别有用。(社区经验)
Remember the decimal-point trick: for 14.195 you only need [1][4][.][1][9][5][ENT] — the radio pads the trailing zeros. That is twice as fast as keying nine digits, and it matters when you QSY to an exact frequency mid-contact. (community-reported)

9.3 以 1 MHz 或 1 kHz 步进调谐Tuning in 1 MHz or 1 kHz Steps

EN

To temporarily set the dial knob to 1 MHz or 1 kHz steps, touch the “MHz” or “kHz” area of the frequency display.

要把调谐旋钮临时设为 1 MHz 或 1 kHz 步进,请触摸频率显示区的 “MHz” 或 “kHz” 位置。

这一功能与 [FINE/FAST] 键的分工是:触摸 “MHz” / “kHz” 得到的是“跨频段式的大步跳跃”(临时、用于快速找频段内的落点);[FINE/FAST] 得到的是“精调 / 10 倍步进”(持续、用于微调或快速扫过)。

找台最顺手的组合:先在频率区触摸 “kHz” 把旋钮变成 1 kHz 步进,几圈之内跨过整段;发现信号后按 [FINE/FAST] 进入 FINE,用 1 Hz 步进把音调调到最自然。整个流程不碰 MENU,也不破坏原有的步进设置。(社区经验)
The smoothest search routine: touch “kHz” on the frequency area so the dial becomes 1 kHz per step and sweep the whole segment in a couple of turns; when you hear something, press [FINE/FAST] for FINE and use 1 Hz steps to bring the pitch to its most natural point. No menus involved, and your original step setting is untouched. (community-reported)

9.5 滤波功能显示Filter Function Display

EN

The filter function display shows the passband status of the Digital filter. The operation of WIDTH, SHIFT, NOTCH, CONTOUR etc. can be observed. The display is drawn differently in SSB mode, CW mode, RTTY mode and PSK/DATA mode, and it also shows the DSP filter bandwidth.

滤波功能显示用于显示数字滤波器的通带状态,可以观察 WIDTH、SHIFT、NOTCH、CONTOUR 等功能的动作效果。该显示在 SSB 模式、CW 模式、RTTY 模式与 PSK/DATA 模式下有不同的画法,同时还会显示 DSP 滤波器的带宽。

EN

Touch the filter display to reveal and check the setting value of the last used function from SHIFT, WIDTH, NOTCH, CONTOUR and APF. Example: when the last function used is the NOTCH function, touching the filter display shows the NOTCH function setting value.

触摸滤波显示区,可以调出并查看 SHIFT、WIDTH、NOTCH、CONTOUR 与 APF 中“上一次使用过的功能”的设置值。例如:上一次使用的是 NOTCH 功能时,触摸滤波显示区就会显示 NOTCH 功能的设置值。

Filter Display滤波显示区(触摸)
触摸:显示上一次使用的干扰抑制功能(SHIFT / WIDTH / NOTCH / CONTOUR / APF)的设置值。长按频谱区域:清除频谱视图,只保留数字滤波器带宽信息;再次长按则恢复频谱显示。Touch to show the setting value of the last used interference-removal function (SHIFT / WIDTH / NOTCH / CONTOUR / APF). Press and hold the spectrum area to clear the spectrum view so that only the digital filter bandwidth information remains; press and hold again to bring the spectrum back.

HAM 实战 · 技术提示FIELD NOTE
把频谱关掉(长按滤波显示区的频谱位置)能显著降低屏幕刷新负担、减少视觉干扰,同时省电——野外电池供电、或者用 CW 长时间窄带守听时,这个操作比调暗屏幕更有效。需要看频谱时再长按一次即可。(社区经验)
Clearing the spectrum (press and hold the spectrum area of the filter display) cuts the screen refresh load, reduces visual noise and saves power — under battery power in the field, or when sitting on a narrow CW channel for hours, it does more good than simply dimming the screen. One more press-and-hold brings the spectrum back. (community-reported)

9.7 [FUNC] 旋钮的显示操作Operation of the Display [FUNC] Knob

EN

The display [FUNC] knob shows the multiple functions that may be operated when the [FUNC] knob is pressed. Normally, it is recommended to adjust the level of the spectrum scope with the [D-LEVEL] knob. The last used function is recalled when the [FUNC] knob is pressed, therefore you can easily call up and then set a function by turning the [FUNC] knob.

显示屏上的 [FUNC] 旋钮显示区,列出按下 [FUNC] 旋钮时可操作的多项功能。平时建议用 [D-LEVEL] 项来调整频谱画面的电平。按下 [FUNC] 旋钮时会调出“上一次使用的功能”,因此可以很方便地调出该功能并直接旋转 [FUNC] 旋钮进行设置。

EN

To change the function of the [FUNC] knob, touch the desired item that appears on the function screen when the [FUNC] knob is pressed and held, or turn the [FUNC] knob to select an item and then press the [FUNC] knob. The last function used is stored as the FUNC knob function and is displayed in the upper right corner of the screen, so it can be easily called up and set by turning the [FUNC] knob. Wait for about 3 seconds, or press the [FUNC] knob, or press the [BACK] key, to confirm the settings and return to the operating screen.

要更改 [FUNC] 旋钮所分配的功能:按住 [FUNC] 旋钮让功能画面出现,触摸想要的项目;或者旋转 [FUNC] 旋钮选中项目后按 [FUNC] 旋钮确认。最后一次使用的功能会被保存为 [FUNC] 旋钮的功能,并显示在屏幕右上角,此后只要旋转 [FUNC] 旋钮即可快速调出并设置。等待约 3 秒,或按 [FUNC] 旋钮,或按 [BACK] 键,即可确认设置并返回操作画面。

表 9-4 [FUNC] 旋钮操作的三种进入方式Table 9-4 Three ways to operate the [FUNC] knob
操作Action 结果Result
按下 [FUNC] 旋钮 调出上一次使用的功能,旋转旋钮即可设置
按住 [FUNC] 旋钮 显示功能画面,触摸目标项目即可把该功能分配给 [FUNC] 旋钮
旋转后再按 [FUNC] 旋钮 在功能画面中旋转选中项目,按下即确认分配
避坑指南PITFALL
[FUNC] 旋钮“记住上次功能”的特性反过来也是一种坑:昨天调过 [D-LEVEL]、今天想调音量却直接旋转它,会变成在改频谱电平,而音量毫无反应。记住判断口诀——要看屏幕右上角的 [FUNC] 功能名,不要凭手感。(社区经验,未证实)
The “last function used” behaviour is a double-edged sword: if you adjusted [D-LEVEL] yesterday, turning the knob today expecting volume will change the scope level instead, and the volume will not move. The rule of thumb: read the [FUNC] function name in the upper-right corner of the screen rather than trusting your muscle memory. (community-reported, unverified)
技术提示TIP
把最常用的功能固定分配给 [FUNC] 旋钮,例如野外操作固定为 [RF POWER] 或 [MIC GAIN],桌面操作固定为 [D-LEVEL] 或 [DNR]。这样每次开机旋一下就是它,不必再进菜单翻页。(社区经验)
Park your most-used function on the [FUNC] knob — [RF POWER] or [MIC GAIN] for field work, [D-LEVEL] or [DNR] at the desk. Then one turn after power-up gets you there, with no menu paging. (community-reported)

SSM-75E 话筒按键

SSM-75E Microphone Switches

本章要点:SSM-75E 话筒上除了 PTT 之外,还有 UP/DOWN、MUTE 以及 P1~P4 四个可编程键,它们分别复刻了前面板的电源/锁定、[QMB]、[MAG]、[V/M] 功能。本章先逐键说明,再给出话筒、耳机与电键的接线定义(8 针话筒插座、φ3.5 耳机插座、3 触点电键插座),最后给出键控接线的注意事项。

10.1 话筒按键Microphone Switches

PTT Switch发射键
切换发射 / 接收:按下即发射,松开即接收。Switches Transmit/Receive. Press to transmit and release to receive.

[UP] / [DWN]上 / 下键
可用 [UP]/[DWN] 键手动向上或向下扫描频率。The [UP]/[DWN] keys may also be used to manually scan the frequency upward or downward.

MUTE静音键
按住 MUTE 键期间,扬声器输出的接收音频会被静音。While pressing the MUTE key, the receiver audio from the speaker will be muted.

Microphone话筒单元
用正常音量说话,话筒距嘴部 5 cm。Speak into the microphone in a normal tone of voice with the microphone 5 cm away from the mouth.

P1可编程键 1:旋钮锁定
切换 MAIN DIAL 旋钮与 SUB DIAL 的 ON/OFF 锁定。锁定(Lock)开启时,MAIN 或 SUB 旋钮仍可旋转,但频率不会改变,屏幕显示 “LOCK”。该键与电台前面板的 [Power] 键功能相同。Toggles the ON/OFF lock for the MAIN Dial knob and the SUB Dial. When “Lock” is ON, the MAIN or SUB Dial knob can still be turned, but the frequency will not change, and “LOCK” appears in the display. Same function as the [Power] key on the front panel.

P2可编程键 2:QMB
把当前操作状态一键存入专用存储频道(QMB:Quick Memory Bank)。该键与电台前面板的 [QMB] 键功能相同。The current operation status can be stored in a dedicated memory channel (QMB: Quick Memory Bank) with one touch. Same function as the [QMB] key on the front panel.

P3可编程键 3:频段切换
短按该键切换到更高的工作频段。该键与电台前面板的 [MAG] 键功能相同。Pressing this key momentarily changes to a higher Operation Band. Same function as the [MAG] key on the front panel.

P4可编程键 4:VFO / 存储切换
切换频率控制方式,在 VFO 与存储系统之间切换。该键与电台前面板的 [V/M] 键功能相同。Toggles frequency control between VFO and the memory system. Same function as the [V/M] key on the front panel.

P2 前面板 [QMB] 键 一键存入 QMB
P3 前面板 [MAG] 键 切换到更高的工作频段
P4 前面板 [V/M] 键 VFO 与存储系统切换
HAM 实战 · 技术提示FIELD NOTE
手持话筒说话时把嘴保持在约 5 cm(两指宽)、略微偏轴 15~30 度,可以明显减少爆破音(p、t 气流冲击)造成的过调制。如果对方反映你的声音发闷或断续,先调整距离和角度,再去动 [MIC GAIN]。(社区经验)
Hold the mic about 5 cm from your mouth and keep it 15–30 degrees off-axis: this markedly reduces plosive blasts from p and t sounds. If the other station reports a muffled or choppy signal, adjust distance and angle before touching [MIC GAIN]. (community-reported)
避坑指南PITFALL
话筒上的 P1 与前面板电源键同功能,但它是“短按即切换锁定”,不会关机——不必担心误触关机。真正的坑是:P1 打开锁定后旋钮仍在自如旋转,只有频率不变,用户往往误判为旋钮故障。屏幕上出现 “LOCK” 即是锁定,再按一次 P1 解除。(社区经验)
P1 on the microphone shares the power key’s function but only toggles the lock — a tap will not power the radio down, so there is no risk of an accidental shutdown. The real trap: with the lock on, the dial still turns freely and only the frequency refuses to move, which users often misread as a broken dial. A “LOCK” indication on screen means it is engaged; tap P1 again to release it. (community-reported)

10.2 话筒、耳机与电键接线Microphone, Headphone, Key and Keyer Connections

EN

The MIC jack is an 8-pin jack that accepts input from a microphone utilising the traditional YAESU HF transceiver pinout. The PHONE jack is a standard φ3.5 stereo jack; inserting a headphone plug into it deactivates the internal and external speakers. The KEY jack is a 3.5-mm, 3-contact jack that accepts a CW key or keyer paddle; a two-contact plug cannot be used in this jack.

MIC 插座为 8 针插座,接受采用传统 YAESU 短波机针脚定义的话筒输入。PHONE 为标准的 φ3.5 立体声插座,插入耳机插头后内部扬声器与外接扬声器均会自动断开。KEY 插座为 3.5 mm、3 触点插座,可接 CW 电键或电子键桨,该插座不能使用两触点(两芯)插头。

表 10-2 话筒(MIC)8 针插座针脚定义Table 10-2 MIC 8-pin jack pinout
针脚Pin 用途Use
FAST 话筒 FAST 键信号
GND 地
PTT 发射键控
MIC 话筒音频输入
MIC GND 话筒音频地
+5V +5 V 供电
UP UP 键信号
DOWN DOWN 键信号
表 10-3 耳机(PHONE)与电键(KEY)插座Table 10-3 PHONE and KEY jacks
插座Jack 规格Type 触点定义Contacts
PHONE 标准 φ3.5 立体声 GND / AUDIO / AUDIO;插入耳机插头后内部与外接扬声器均断开
KEY 3.5 mm、3 触点 KEY / NC / GND;电子键桨接线时使用 DOT / DASH / COMMON 标记;键抬起电压 +5.0 V DC,按下电流 3 mA

10.3 键控连接要点Keying Connection Notes

EN

When connecting a single straight key, the key closes the keying line to ground. When connecting an electronic keyer paddle, the DOT, DASH and COMMON contacts are used. In both cases the key-up voltage is +5.0 V DC and the key-down current is 3 mA; a two-contact plug cannot be used in this jack.

连接单杆键(straight key)时,电键把键控线对地闭合;连接电子键桨(keyer paddle)时,使用 DOT、DASH 与 COMMON 三处触点。两种情况下的键抬起电压均为 +5.0 V DC,按下电流均为 3 mA;该插座不能使用两触点(两芯)插头。

注意NOTE
使用话筒时请注意:插入耳机插头会自动断开内部扬声器与外接扬声器(原厂说明)。若你使用外接扬声器监听,又插入了耳机,声音会全部转到耳机侧。
Note that inserting a headphone plug into the PHONE jack deactivates both the internal and the external speaker. If you monitor through an external speaker and then plug in headphones, all audio moves to the headphones.
技术提示TIP
自制或更换话筒时,先按表 10-2 核对 FAST / PTT / MIC / MIC GND / +5V / UP / DOWN 七个信号线的位置,尤其不要接错 +5V 与 MIC GND——接错会同时损坏话筒和电台的偏置电路。使用原厂 SSM-75E 时无需担心此问题。
If you build or replace a microphone cable, check the FAST / PTT / MIC / MIC GND / +5V / UP / DOWN signals against Table 10-2 first — in particular never swap +5V and MIC GND, which can damage both the microphone and the radio’s bias circuit. With the stock SSM-75E this is not an issue.
