Description
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.

Great radio works as it should
AM and FM power is good. Nice looking with many features.
very good radio build quality and looks are fantastic All of the writing on the faceplate lights up and the frequency counter is large and easy to read
This radio rocks y’all! Great quality radio, and it transmits and receives very well. I am very happy with this purchase, and I will be buying alot more radios from Retevis. I love the lay-out and functions as well. It’s priced great and IMO, a very high quality radio. It amazes me how nice this radio is for the price. Buy one for you and one for a friend haha, you won’t regret it.
Great radio!good modulation easy to configure on a pc
Very good radio.After couple of weeks of use it is very easy to use all the functions,compared to the Anytone 5555N II . I own both and prefer the HS4 and it was the cheaper one.
This HS4 is a very capable 10 meter all band/ extended transmit transceiver, and for an affordable price! I discovered a small issue (most people would not even notice) and the nice lady (Amber) at customer service was a gem in helping me get the radio replaced without much issue. I strongly recommend checking out this radio and company!
Just got my HS4 Ten meter radio really love this radio it works amazing like a champ well recommended really easy to convert to 11 meters here is how push and hold the function button and the emergency button at the same time and then turn on your radio. You will see one band turn the channel selector to the right and we'll see two band and then hold the function button until you see end reset. and that's it turn off the radio ! You good to go after this ! 💪🥊🔥
