Retevis Ailunce HS4 10 Meter SSB Ham Radio AM/FM/PA/USB/LSB/CW Mobile Transceiver
The Retevis Ailunce HS4 is a high-performance 10m SSB amateur radio designed for reliability and versatility for both mobile and base station operations. Its large LCD display clearly displays all frequencies, while the LED channel number indicator ensures that operators can easily monitor critical information. This SSB mobile transceiver is equipped with a user-friendly VFO knob and adjustable step value to quickly and accurately adjust frequencies for seamless communication. In addition, the HS4 supports 6 modes (PA/AM/FM/USB/LSB/CW) to accommodate a variety of scenarios, from emergency communications to safe CW mode operation using an external Morse device. The dual monitoring function automatically switches between two frequencies. This long-range mobile radio uses squelch and noise reduction technology to provide clear audio even in noisy environments. With its durability and easy integration, the HS4 is the first choice for amateur radio operators seeking a rugged, feature-rich 10m ham radio for mobile or base station use.
Long range mobile radio
high power mobile transceiver has strong penetration offers a long-range communication. shortwave design breaks the communication limitation; a 10-meter radio communicates stably and smoothly.
6 optional modes
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 communicate6 frequency bands
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 display
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
Clear sound quality
long range mobile radio not only supports squelch function but also supports noise reduction function. when the transmitter is in a noisy environment,operators receive clearly.
104 CTCSS/DCS
ssb ham radio increases the security of communication by blocking out other conversations on the same frequency; improving communication efficiency
SWR protection
effectively protect 10 meter ham radio from damage when the SWR is too high; extending the use time of ham radio base station
Dual watch function
mobile transceiver can watch and receive on two frequencies alternatively and automatically, operators won't miss important calls
Keypad lock
comes with a lock key, mobile ham radio prevents changing frequencies or setting from mis operations; especially during busy periods
VFO knob
amateur mobile transceiver supports adjusting the frequencies by rotating the VFO knob based on the optional step values; making operations more convenient.
