Whether you are new to the hobby or have been a licensed operator for decades, knowing how to scan radio frequencies efficiently is one of the most practical skills you can have. The RETEVIS Ailunce HA2 is a capable handheld, but its scanning features are only useful if you know how to configure them properly. This guide will show you exactly how to use the scan function to monitor your local area without the headache of complex menus.
Why Use the Scan Mode on Your HA2?
Most operators use their RETEVIS Ailunce HA2 for local repeater work. However, radio scanning unlocks the full potential of this radio's hardware. With its dedicated airband scan radio support (108.0000–135.9750 MHz) and wideband receive ham radio capabilities, you can monitor aviation traffic, and local government services, and even FM broadcast stations. Instead of manually scrolling through frequencies, your RETEVIS Ailunce HA2 automatically finds active conversations for you.

Setting Up Your Custom Scan Lists
The RETEVIS Ailunce HA2 allows you to organize your listening by creating up to 16 different scan lists. Each scan list ham radio can store up to 100 channels, making it easy to separate your local ham repeaters from other interests like aviation or marine frequencies.
1. Create a New Scan List
To start, you need to create a list to hold your favorite frequencies.
-
Press the Menu button on your RETEVIS Ailunce HA2.
-
Navigate to Scan and select Channel List Scan.
-
Choose Add Scan List and enter a name like "Local Ham" or "Airband."
2. Add Channels to Your List
Once the list is created, you need to populate it with channels already saved in your radio's memory.
-
In the scan menu, select Channel List.
-
Choose the channels you want to monitor and press Menu to add them.
-
If you need to make changes later, simply select the channel and choose Delete.



3. Priority Channel Scan
For critical monitoring, the RETEVIS Ailunce HA2 supports priority channel scan. You can designate up to two priority channels. During a scan cycle, the radio will frequently "check back" on these channels, ensuring you never miss a call on your primary frequency even while scanning other channels.

VFO Scan Settings
When you want to search for new activity that isn't already saved in your memory, you'll use the VFO scan. The RETEVIS Ailunce HA2 gives you two specific ways to start this frequency scan, which you can find under the VFO Scan Set menu:
-
Current Frequency: Selecting this means the scan will start exactly from the frequency currently displayed on your screen. This is perfect for a quick check of the frequencies immediately surrounding your current position.
-
Starting Frequency: This option allows you to perform a more structured ham radio frequency sweep. You can set a specific Start Frequency and Stop Frequency to scan a precise range, such as the entire airband or a specific segment of the 2-meter band.

How to Start and Stop Scanning
You don't need to navigate menus to begin scanning once your settings are ready.
-
To Start: In standby mode, long-press the [SCAN] key.
-
To Stop: Simply short-press the [SCAN] key.
The radio will automatically follow your current mode. If you are in channel mode, it runs your memory channel scan. If you are in VFO mode, it begins a VFO scan.

If you still feel confused about any scanning operation or encounter setup hiccups, you can refer to the official YouTube operation video for more intuitive and detailed guidance.
Scanning is one of the most rewarding ways to use your RETEVIS Ailunce HA2. Whether you're tracking local nets or listening to the local airport tower, these steps will help you hear more of what's happening around you.
