USDR uSDX 6 Bands SDR Transceivers 80m 40m 20 17m 15m 10m QRP SSB/CW HF Transceivers 5W Aluminium Cover 0.9 Inch OLED Display

Note:

Theoretically, AM and FM modes are supported, but the effect of these two modes is very poor, which can be almost useless. If you need a normal radio station in AM and FM mode, please do not buy this product.

Features:

EER Class-E driven SSB transmit-stage and approximately 5W PEP SSB output from 13.8V supplys.

Multiple DSP features: Automatic Gain Control, Noise-reduction, Voice-triggered Xmit, RX Attentuators (ATT), TX noise gate, TX drive control, volumes control, dBm/S-meter.

SSB opposite side-band/carrier supression Transmit: better than -45dBc, IMD3 (two-tone) -33dBc, Receive: better than -50dBc.

Multiband support and continuously tunable through bands 160m-10m (and from 20kHz..99MHz with loss in performance), give you a better using experience.

Software-based VOX that can be used as quick Full Break-In (QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes (no C-AT or PTT interface required), external PTT output/PA control with TX-delay.

Simple to install modification with 8 component changes and 8 wires.

For the EER transmitters class-E stage it is highly power-efficient (no bulky heatsinks required), and has a simple design (no complex balanced linear power amplifier required).

Fully digital design and software-based SSB transmit-stage: samples microphone-input and reconstruct a SSB-signal by controlling the phase of the SI5351 PLL (through tiny frequency changes over 800kbits/s I2C) and the amplitude of the PA (through PWM of the PA key-shaping circuit).

Three independent switchable analogs front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB).

VFO A/B + RIT and Split, and corresponding relay band-filter switching via I2C, C-AT support (TS480 subset), possibility to stream audio, keys, display-text over C-AT.
