List of features:Simple, and versatile QRP SSB HF transceiver with embedded DSP and SDR functions; EER Class-E SSB transmit-stage Approximately 5W PEP SSB output from 13.8V supply All-Mode support: USB, LSB, CW, AM, FM DSP filters: 3000, 2500, 1700, 500, 200, 100, 50 Hz passband DSP features: Automatic Gain Control (), Noise-reduction (), Voice-triggered Xmit (), RX Attentuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter. SSB opposite side-band/carrier supression Transmit: -45dBc, IMD3 (two-tone) -33dBc, Receive: -50dBc Multiband support, continuously tunable through bands 160m-10m (and from 20kHz..99MHz with loss in performance) firmware, built with for IDE; allows experimentation, new features can be added, contributions can be shared via Github, software-complexity: 2000 lines of code Software-based that can be used as fast Full Break-In (QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes (no or PTT interface required), external PTT output/PA control with TX-delay Simple to install modification with 8 component changes and 8 wires Lightweight and low-cost transceiver design: because of the EER-transmitter class-E stage it is highly power-efficient (no bulky heatsinks required), and has a simple design (no complex balanced linear power amplifier required) Colour:black Material:Aluminum alloy Size:38 x 88 x 155mm Package Contents: 1 * USDX SDR Transceiver Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
