USDR USDX 6 Bands SDR Transceivers 80m 40m 20 17m 15m

Note:

AM and FM modes are free bonus features that don't work very well. Please make sure that you don't mind before purchasing. Thank you!

If you are interested in the functions of these two modes, please buy a regular radio.

This is a simple and powerful QRP SSB HF transceivers with embedded DSP and SDR functions, the small size allows you carry it easily, USB, LSB, CW, AM, F-M all-Mode support function can give you a better using experience. Come and have a try, it will not let you down.

Features:

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

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

SSB opposite side-band/carrier supreion 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 lo 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 aist 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 cla-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), poibility to stream audio, keys, display-text over C-AT.
