前面板按键与旋钮详解 6 CHAPTER 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 Front Panel Overview · 前面板全貌

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

FTX-1 Field 的前面板可归纳为“三个纵向区、两条横向 The front panel of the FTX-1 Field is organized into three 排”。左区是 SUB 侧控件,右区是 MAIN 侧控件(含大 vertical zones and two horizontal rows. Left zone: the SUB- 直径主调谐旋钮),最下方一行是与频谱相关的 6 个屏幕 side controls. Right zone: the MAIN-side controls, including 软键;顶边一行则集中了 GM、S-DX、PMG、MAG、 the large main tuning dial. Bottom row: the six on-screen N/W、SPLIT、V/M 与 M-V 等功能键。 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.

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

SUB DIAL 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)。 SUB 侧调谐旋钮 Rotate to tune the frequency of the SUB-side. Each press swaps the MAIN-side and the SUB-side.

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

MAIN DIAL 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)。 MAIN 侧主调谐旋钮 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 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 功能旋钮 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-MAIN 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 MAIN 侧音量 / RF 增 RF 增益。旋钮上方印有 MAIN 与 [DSP] 方框第二功能丝印。 益 / 静噪旋钮 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 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 快速存储键 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 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。 清晰度(Clarifier)键 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 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。 显示切换键 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.

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 BUSY/TX 指示窗位于 [QMB] 与 [CLAR] 之间、主调谐旋 The BUSY/TX indicator sits between [QMB] and [CLAR], 钮上方,丝印为 "BUSY/TX SUB MAIN"。静噪打开时该 above the main dial, and is marked "BUSY/TX SUB MAIN". 指示亮绿色(C4FM 下为蓝色),发射时亮红色。需要注 This indicator glows green (blue in C4FM) when the 意:只有当 [AF/RF/SQL] 旋钮被设为 "SQL" 或 "AUTO" squelch opens, and glows red during transmit.

S-DX 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。 超级 DX 键 Press to enable the Super DX function and increase sensitivity. Press and hold to save the TFT screen image to the microSD card.

PMG 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。 主存储组键 Press to display the PMG (Primary Memory Group). Press and hold to register the displayed frequency in the PMG.

MAG 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 存储频道频段自动分组 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。 键 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 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 窄带 / 工作模式键 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.

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

TFT 屏幕下沿有 6 个触摸软键:CENTER、3DSS、 Along the bottom edge of the TFT screen there are six MULTI、SCOPE、SPAN 与 SPEED,它们属于频谱显示画 touch soft keys: CENTER, 3DSS, MULTI, SCOPE, SPAN and 面。软键上方是频谱的频率轴,例如在 Dual band(左 SPEED.

6-7 Key Difference of the [AF/RF/SQL] Knobs · [AF/RF/SQL] 旋钮的模式差异(重点)

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。

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
