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.
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
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.
ssb ham radio increases the security of communication by blocking out other conversations on the same frequency; improving communication efficiency
effectively protect 10 meter ham radio from damage when the SWR is too high; extending the use time of ham radio base station
mobile transceiver can watch and receive on two frequencies alternatively and automatically, operators won't miss important calls
comes with a lock key, mobile ham radio prevents changing frequencies or setting from mis operations; especially during busy periods
amateur mobile transceiver supports adjusting the frequencies by rotating the VFO knob based on the optional step values; making operations more convenient.
