Ailunce HS4 10 Meter 28.000MHz-29.700MHz Ham Radio 6 modes switch; 10 meter ham radio supports PA/AM/FM/USB/LSB/CW modes; which meet flexible use needs; in addition; CW mode can connect the external Moss devices to achieve secure communication 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 Large LCD display Amateur radio has an LCD display for showing complete frequencies and function operations; and has an LED display for showing channel numbers; in both daytime and nighttime; mobile ham radio information is clear and intuitive to see Clear sound quality 10 meter ham radio features noise reduction function and squelch function; when the transmitter is in a noisy environment; operators receive clearly Long range mobile radio; High power offers a long range communication; shortwave design breaks the communication limitation; 10 meter radio communicates stably and smoothly Strong CompatibilityExcept for the equipped dynamic microphone, amateur radio is compatible with a condenser microphone (not included). Dynamic microphone provides good sound quality. Operators choose based on the specific needs. Voltage Protection When the voltage of the ham radio base station is over a certain level, the amateur mobile transceiver will cut off automatically to protect 10 meter radio from damage.
