### **Basic Operation of the Yaesu FT-891**

Before diving into programming, let's go over some of the key controls to get you started with everyday operation.

#### Powering On and Off

• - **Power On**: Press and hold the **[PWR] button** on the front panel for about 1 second.
• - **Power Off**: Press and hold the **[PWR] button** again for about 1 second.

#### Tuning the Frequency

• - Use the **Main Dial** to tune the frequency. This large knob allows you to easily scroll through frequencies.
• - Press the **[CLAR/VFO-B] button** to switch between VFO-A and VFO-B, which allows you to monitor and switch between two frequencies.

#### Adjusting Volume and Squelch

• - **Volume**: Rotate the **VOL knob** (located above the Main Dial) to adjust the volume.
• - **Squelch**: Rotate the **SQL/RF knob** (beside the VOL knob) to set the squelch level, reducing noise when no signal is present.

#### Switching Bands

• - To switch between bands (e.g., 20 meters, 40 meters), press the **BAND button** and rotate the **Main Dial** to select your desired band.

### **Manual Programming of Memory Channels**

The Yaesu FT-891 has 100 memory channels for storing your favorite frequencies, making it easier to switch between them quickly. Here’s how you can manually program these channels.

#### Step 1: Select the Desired Frequency

1. 1.

   **Set the Frequency**: Use the **Main Dial** to tune to the desired frequency.

   • - For example, you might want to set a frequency for 20 meters, such as 14.250 MHz.

#### Step 2: Set the Desired Operating Parameters

Before saving a memory, adjust any necessary parameters:

1. 1. **Clarifier/Shift**: Adjust the clarifier if needed by pressing the **[CLAR] button** and turning the **Main Dial**.
2. 2. **Squelch and RF Gain**: Set the squelch and RF gain as needed for the frequency you're operating on.

#### Step 3: Save the Frequency to a Memory Channel

1. 1. **Press and hold the [V/M] button** for 1 second**. This enters the memory write mode.
2. 2. The display will show an available memory channel (e.g., “M-001”). You can use the **Main Dial** to scroll through available memory slots.
3. 3. Once you've selected the desired memory slot, **press and hold [V/M] again** to save the frequency.

#### Step 4: Assign a Memory Tag (Optional)

You can assign a name (tag) to each memory channel for easy identification.

1. 1. Press **[FUNC]**, then use the **Main Dial** to select **MEM TAG**.
2. 2. Enter the name using the multi-function buttons and dial. You can assign names like "20M USB" or "Local Net."
3. 3. Press **[FUNC]** again to save the tag.

### **Using Memory Channels**

Once you’ve programmed a few frequencies into the memory channels, switching between them is easy:

1. 1. **Press the [V/M] button** to switch from VFO mode to Memory mode.
2. 2. Use the **Main Dial** to scroll through your saved memory channels.
3. 3. When the desired memory channel is displayed, press **[V/M]** again to operate on that frequency.

### **Advanced Features**

The Yaesu FT-891 is packed with features that cater to both casual and advanced operators. Here are a few key features that can enhance your experience.

#### Noise Reduction (NR)

The **NR (Noise Reduction)** feature helps reduce background noise, improving signal clarity in weak conditions.

1. 1. Press **[FUNC]**, then use the **Main Dial** to select **NR**.
2. 2. Press **[ENT]** to enable or disable noise reduction.

#### Automatic Notch Filter (DNF)

The **DNF** feature automatically removes unwanted carriers (e.g., heterodynes) during voice reception.

1. 1. Press **[FUNC]**, then use the **Main Dial** to find **DNF**.
2. 2. Press **[ENT]** to turn DNF on or off.

#### Digital Signal Processing (DSP)

The FT-891 has built-in DSP filters that help in improving signal clarity:

1. 1. Press **[FUNC]** and use the **Main Dial** to select **DSP** settings.
2. 2. You can adjust bandwidth, contour, notch filter, and more to tailor your receiving signal.

#### RF Power Control

You can adjust the output power level to suit different conditions (from QRP low-power operations to full 100W output).

1. 1. Press **[FUNC]** and scroll to **RF POWER**.
2. 2. Turn the **Main Dial** to adjust the output power level.

### **Programming Using a Computer (Optional)**

While the Yaesu FT-891 allows for manual programming, it’s much easier to program using a computer and software such as **CHIRP** or **Yaesu’s ADMS-891 software**.

#### What You’ll Need:

• - **Programming cable** (e.g., Yaesu SCU-17 or another compatible cable).
• - **Software**: You can download **CHIRP** (open-source) or the official **ADMS-891** software from Yaesu’s website.

#### Steps for Programming with Software:

1. 1. **Install the software** on your computer and connect the FT-891 using the programming cable.
2. 2. **Read from the radio**: Open the software, connect to your FT-891, and download the current settings from the radio.
3. 3. **Program Frequencies**: Add frequencies, memory channels, and other settings directly through the software interface.
4. 4. **Upload to the radio**: Once you’ve finished configuring the settings, upload them back to the radio.

This method allows you to easily manage multiple memory channels and fine-tune settings without manually inputting everything through the radio’s interface.
