10W Max USDX + USDR HF QRP SDR SSB/CW Transceiver 5W 8 Bands Shortwave Radio - US Plug

This is a shortwave QRP SSB/CW transceiver, it adopts a 1602 screen and with built-in battery, also comes with a recharger for you to use together. With powerful functions such as CW decoding, 8 bands, full bands support and so on.

• This transceiver adopts IRF series launching tube and can be used by connecting the antenna (M seat)
• Full mode support: USB, LSB, CW, AM, FM. Multi-band support, continuously adjustable in the 160m-10m frequency band (and performance loss from 20kHz..99MHz)
• DSP filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband and with powerful DSP functions: automatic gain control (AGC), noise reduction (NR), voice trigger, voice trigger Xmit, RX attenuator (ATT), TX noise gate, TX driver control, volumes control, dBm/S-meter
• Software-based voice trigger Xmit can be used as a quick full invasive (QSK and semi-QSK operation), or to assist in running in digital mode (without C-AT or PTT interface) for RX/TX switching, external PTT output with TX/PA control-delay
• Thanks to EER transmitters E-level, it has high power efficiency (no bulky heat sink required), and simple design (no need for complex balanced linear power amplifiers)
• SSB transmitters stage based entirely on digital and software: By controlling the phase of the SI5351 PLL (via the tiny frequency change of I2C over 800kbit/s) and the amplitude of the PA (via the PWM of PWM) to sample the microphone input and reconstruct the SSB signal. PA keys shaping circuit)
• Fully digital and software-based SDR receiver stage (optional): sample the I/Q (complex) signal from the quadrature sampling detector digital mixer, and perform a 90-degree phase shift in the software (Hilber transform) and eliminate one by adding sidebands
