Retevis Ailunce HS4 10-12 Meter SSB Ham Radio AM/FM/PA/USB/LSB/CW Mobile Transceiver
Sky-Wave Communications
6 Operational Modes
The Retevis HS4 (Quad 5 AT-5555) 10+ Meter Mobile CB Style Amateur Ham Radio - 2024 Version With CTCSS/DCS provides a significant advantage in versatility with its PA/AM/FM/USB/LSB/CW modes. Additionally, the CW mode allows for operating morse code with a 2.5mm key plug for a truly satisfying experience.6 Channelized Zones - Maximum Coverage
This SSB ham radio offers versatile communication capabilities with A/B/C/D/E/F frequency bands. Operators can choose the appropriate portion of the band for flexible communication, regardless of their location, making this mobile transceiver an essential tool for effective communication.
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.
