- Retevis Ailunce HS4 10 Meter SSB Ham Radio AM/FM/PA/ Mobile HF Transceiver
Retevis Ailunce HS410-meter radio boasts a 40-watt transmission power and 28.000-29.695MHz (24.7150 to 30.1050 MHz possible) frequency range that delivers crystal-clear communication over long distances, making it an ideal choice for radio amateur enthusiasts, truckers, and emergency responders.
- Ailunce HS4 is a Long-range mobile radio
The high-power mobile transceiver has strong pe*******on and offers long-range communication. shortwave design breaks the communication limitation; a 10-meter radio communicates stably and smoothly.
Under normal conditions, the 10-meter band can typically support communications over distances of several hundred miles (or kilometers) using SSB voice.
Ailunce HS4 supports SSB mode, so it is a long-range ham radio.
- 6 Optional modes
HS4 10-meter radio increases the flexibility of use through the PA/AM/FM/USB/LSB/CW modes; meanwhile; CW mode makes it secure to communicate by connecting the external Moss devices to communicate
Ailunce HS4 10-meter radio supports 6 modes of operation, including SSB(Single Side Band), CW (Continuous Wave), AM (Amplitude Modulation), FM (Frequency Modulation), PA mode, and CW mode.
This HS4 covers what you want on a 10-meter radio. Whether you are on your favorite FM/AM station, or communicating in SSB or PA mode. Ailunce HS4 will be your best choice on a 10-meter band mobile radio.
- 6 Frequency Bands for Ailunce HS4 amateur radio.
This HS4 SSB ham radio supports A/B/C/D/E/F frequency bands. The mobile transceiver provides operators with flexible communication options. No matter where you are, choose the proper one to achieve communication flexibly.
- Large LCD Easy-to-operate 10-meter Band radio
HS4 ham radio base station displays the complete frequencies and function operations on the LCD. Displays the channel numbers on the LED, whenever and wherever; operators easily check the radio information.
- Loud and Clear sound quality with Noise reduction and ECHO Sound
The noise reduction function allows HS4 to get a clear sound, even when the transmitter is in a noisy environment. Echo sound will help to get loud sound. Rotate the k**b to adjust the echo sound effect and interval, making the voice louder and be heard by more operators in an open area.
- 104 CTCSS/DCS
SSB ham radio increases the security of communication by blocking out other conversations on the same frequency; improving communication efficiency.
The CTCSS/DCS codes allow users to communicate with each other on the same code. You may configure the specific code, it will provide you with a secure and confidential platform.
- SWR protection
The SWR protection function effectively protects your HS4 10-meter ham radio from damage when the SWR is too high; extending the use time of ham radio base station.
- Dual watch function
Keep connected with the dual watch feature. When the HS4 activates the dual watch feature, the screen displays the "DW" icon, indicating the simultaneous monitoring of two channels. This ensures you never miss crucial conversations or incoming transmissions, maximizing communication efficiency.
- Keypad lock
HS4 comes with a lock key, mobile ham radio prevents changing frequencies or settings from operations; especially during busy periods
- VFO k**b
This amateur mobile transceiver HS4 supports adjusting the frequencies by rotating the VFO k**b based on the optional step values; making operations more convenient.
- Strong Compatibility
Strong Compatibility with accessories( The standard package not include this microphone)
HS4 can work with Dynamic and Condenser microphones, increasing flexibility.
- Backlight design with 3-Levels to adjust
Ailunce HS4 HAM Radio can adjust the backlight. There are 3 Levels. Radio amateur Operators adjust the backlight level from 1 to 3 according to the actual environment. It is easy to check whether indoors or outdoors conveniently.
