-
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.
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.
