PMG 主存储组（VHF/UHF） 14 CHAPTER PMG (Primary Memory Group)
本章要点：PMG（主存储组）是 FTX-1 面向 VHF/UHF 的多频点值守工具：最多注册 5 个信道，用条形图实时显示各信道的接收 状态，并可同时收听其中两个有信号的信道。本章讲解 PMG 画面的读法、频率的注册与取消注册、Manual / Auto 两种模式的 差别，以及与 M-GRP、MAG 等其它存储体系的分工。
PMG 功能对注册到 PMG 的最多 5 个信道进行扫描。各 The PMG function scans up to 5 channels registered to the 信道的接收状态以条形图实时同时显示。此外，可同时接 PMG.

In addition, two channels with signals are simultaneously received, allowing "手动模式"与"自动模式"的操作有所不同。PMG 功能仅在

14-5 PMG versus M-GRP and MAG · PMG 与 M-GRP / MAG 的区别
PMG、M-GRP 与 MAG 是三种不同的信道分组与调出方 PMG, M-GRP and MAG are three different ways of 式，解决的问题各不相同。PMG 同时监测最多五个已注册 grouping and recalling channels, and they solve different 信道，并可同时接收其中两个。MAG（存储信道波段自动 problems. PMG monitors up to five registered channels at 分组）在存储模式下，每次按键只把同一频率波段的存储 the same time and can receive two of them simultaneously. 信道成组调出。M-GRP（存储组）是用户自建的清单：不 MAG (Memory Auto Grouping) recalls, in memory mode, 分波段，可预先注册并作为常用存储信道调出。 only the memory channels of the same frequency band as a group. M-GRP (Memory Group) is a user-built list: channels, regardless of the band, can be registered in advance and called up as frequently used memory channels.

注意 · 三个体系互不相通 NOTE
把频率注册进 PMG，并不会同时把它加进 M-GRP；反之亦然。M-GRP 只作用于存储信道（需先按 [V/M] 键进入存储信道列 表），而 PMG 可以直接注册当前 VFO 频率。另外，PMG 只支持 AIR / 144MHz / 430MHz 波段，在 HF 波段按住 [PMG] 键不会注册成功。 Registering a frequency into PMG does not add it to M-GRP, and vice versa. M-GRP applies only to memory channels (you must first press the [V/M] key to open the memory channel list), whereas PMG can register the current VFO frequency directly. In addition, PMG supports only the AIR / 144 MHz / 430 MHz bands — pressing and holding the [PMG] key on an HF band will not register anything.
HAM 实战 · VHF/UHF 常用频点快速切换的实战用法 FIELD NOTE
推荐把 PMG 当成"五个常用频点的仪表盘"来用：①把本地中继上行/下行（注意只注册你能合法发射的频点）、常用 Simplex 呼叫频点（如 144MHz 与 430MHz 各一个）、AIR 波段一个感兴趣的频点、以及一个临时活动频点注册进去；②日常守听用 手动模式，把主用频点锁定在 P1，其余四个后台扫描，有人呼你时能第一时间在条形图上看到；③野外架台或临时活动时用自 动模式，机器会自己跳到最先有信号的频点，适合"谁先出来我先跟谁通"的场景；④静噪一定要在 PMG 画面下用 MAIN 侧 AF/RF/SQL 旋钮按下再旋转来调——这个设定对所有注册信道统一生效，逐个信道调是不行的；⑤注意注册是 FIFO 的：注册 第 6 个频点时最早的那个会被自动删掉，重要频点建议同时存成存储信道做备份；⑥如果两个信道同时有信号但你想听第三 个，先旋转 DIAL 把发射信道切过去，其余信道仍在后台扫描。（社区经验） Treat PMG as a "dashboard for five favourite channels". (1) Register your local repeater pair (only frequencies you are licensed to transmit on), one favourite simplex calling frequency each on 144 MHz and 430 MHz, one AIR-band frequency of interest, and one ad-hoc event frequency. (2) Use Manual Mode for everyday standby: lock your primary channel on P1 and let the other four scan in the background, so that anyone calling you shows up on the bar graph immediately. (3) Use Auto Mode for portable or special-event operation, where the radio jumps to whichever channel comes up first — ideal when you want to work whoever appears first. (4) Always set the squelch on the PMG screen by pressing and turning the MAIN-side AF/RF/SQL knob; this setting applies uniformly to all registered channels and cannot be set per channel. (5) Registration is FIFO: registering a sixth frequency silently deletes the oldest one, so keep important channels saved as regular memory channels as a backup. (6) If two channels are active but you want to work a third, rotate the DIAL to move the transmit channel there first; the remaining channels keep scanning in the background. (community-reported)
