About this item:
Long range mobile radio;
whether you are an amateur radio operator; emergency responder; or outdoor off-road adventure enthusiast; it provides long-distance communication; the shortwave design breaks through communication limitations, allowing you to communicate stably and smoothly.
Clear sound quality:ham radio features noise reduction function and squelch function; when the transmitter is in a noisy environment; operators receive clearly.6 modes switch: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: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 .Two-kind Backlight:The keys will display a green color in the dim light. Work with backlight adjustment, radio is easy and convenient to operate.Strong Compatibility:
Except 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 radio from damage.SWR protection:effectively protect 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.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. Package Include：
1 X Radio
1 X USB Type-C Charging Cable
1 X Power Cable
1 X Main Bracket
1 X User’s manual
1 X Screw
1 X MicrophoneAbout SSB:SSB, or Single Side Band, is a radio mode that includes two types: LSB (lower sideband) and USB (upper sideband). Here’s how they connect:How they work technically: Imagine a garden hose with a spray nozzle that cannot be regulated. closing most of the holes on that spray nozzle with duct tape, leaving only ONE hole open. If that hole is at the bottom of the nozzle, that would be LSB. If it’s on the top side of that nozzle, that would be USB.Hence,Both USB and LSB are forms of SSB, and they carry the exact same useful information—only one uses the higher-frequency part of the original signal, and the other uses the lower-frequency part.In SSB mode, you only transmit power when speaking, no transmission when there is no sound, and the power is more concentrated.Notes on using SSB mode：Similar to "watering a flower in the distance", you need to adjust the radio's "clarity knob" (tuning) to the most accurate frequency in order to clearly receive the other party's radio signal.Where they sit on the frequency spectrum: Think of radio frequencies as a number line. The "carrier wave" sits at a specific middle frequency (say, 10 MHz). USB uses frequencies above this carrier (for example, if the audio being transmitted ranges from 500 Hz to 3 kHz, USB would use 10.0005 MHz to 10.003 MHz). LSB uses frequencies below the carrier (in the same example, that would be 9.9995 MHz to 9.997 MHz).When people use which one: Which one you pick (USB vs. LSB) depends on what you’re communicating and the radio band you’re using. For example:
In ham radio (amateur radio), people usually use LSB on HF bands (shortwave frequencies, like 40 meters or 20 meters) and USB on VHF/UHF bands (higher frequencies, like the 2-meter band used for local talking).
In marine (ship-to-ship or ship-to-shore) communications, LSB is often used for digital messaging. Transmitter
