New Designed Waterproof Handheld HF SSB Transceiver
HF SSB Radio is a radio communication equipment sending and receiving signals from either of the two sidebands of AM Signal.
The transmission system of SSB Radio is divided into a prototype single-sideband system
and an independent single-sideband system,
the former only transmits the information from the upper sideband and the first sideband,
and the later transmits different types of information between the upper and the lower sidebands.
One sideband (with the bandwidth of 3 kHz) can transmit one-route call, multi-route telegram or data. Compared with the AM radio station, it has virtues of frequency spectrum saving, power saving, ease of reuse, as well as slight effects by the selective fading.
In addition, it has multi working modes such as continuous wave, frequency-shift printing telegram, single sideband call and amplitude-modulation call,
mainly used for the long-range and BVR communication.
