Descripción

Product description Previous page Clear Sound Quality Adopting the reception noise reduction, the ham radio receives clearly in a noisy environment. High Power Mobile Transceiver 10 meter shortwave ham radio has no call limitation and ensures stable calls over a distance. Flexible Operations 10 meter radio has CW, SSB, PA total 6 modes. CW mode outputs a high power for better transmission. Next page 1 Noise Reduction Function 2 Long Range Mobile Radio 3 Multi-mode Switch Dual Watch The ham radio base station supports a dual watch function. It enables operators to watch and receive on two frequencies automatically without missing important information. It helps enhance communication. 6 Frequency Zones Equipped with A/B/C/D/E/F 6 frequency bands, 10 meter radio enables operators to choose and set the needed channel and frequency in a specific zone quickly and conveniently. Each frequency band has 60 channels to set. Backlight Design The keys will display a green color in the dim light. Work with backlight adjustment, 10 meter radio is easy and convenient to operate. Roger Beep Activate the RB function, the mobile ham radio sends a tone at the end of the transmission from the operator, increasing the convenience of use. Voltage Protection When the voltage is over a certain level, the amateur mobile transceiver will cut off automatically to protect 10 meter radio from damage. External Speaker Jack 3.5mm port, onnect the external speaker to make the voice sound loud, hearing clearly while in noisy traffic conditions.

Características

• Long range mobile radio; whether you are an amateur radio operator; emergency responder; or outdoor off-road adventure enthusiast; HS4 mobile transceiver provides high-power long-distance communication; the shortwave design breaks through communication limitations, allowing you to communicate stably and smoothly within 10 meters.
• 6 modes switch; 10 meter ham radio supports PA/AM/FM/USB/LSB/CW modes; CW mode can connect the external Moss devices to achieve secure communication; AM for long range calls; FM for clear sound; SSB(USB+LSB) for voice modulation; PA for public address
• Large LCD display; ham radio base station displays the complete frequencies on the LCD; frequency counter is large and easy to read; numbers on the LED; All of the writing on the faceplate lights up; operators easily check the radio information even at night
• VFO knob; amateur mobile transceiver supports adjusting the frequencies by rotating the VFO knob based on the optional step values; making operations more convenient
• 6 frequency bands; ssb ham radio supports A/B/C/D/E/F frequency bands; no matter where you are; choose the proper one to achieve communication flexibly
• Clear sound; 10 meter ham radio features noise reduction function and squelch function; when the transmitter is in a noisy environment; operators receive clearly
• Dual watch function; mobile transceiver can watch and receive on two frequencies alternatively and automatically; operators won't miss important calls
• 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
