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
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.
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.
