Tiktok Viral Usdx 80m/40m/20/17m/15m/10m 6 Bands Usdr Hf Qrp Sdr Transceiver New Style [yntVsEgK]

Description:

Size: 38*88*155mm(Aluminum case)

Standby current: 13.8vdc 80--90ma

Full HF reception, commonly used 6-band transmission design:80m/40m/20/17m/15m/10m

Over view：

This is a shortwave QRP SSB/CW transceiver.

The ultra-small size makes it easy to carry for outdoor use.

It adopts 0.91inch OLED screen.

List of features:

- Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR functions;

- EER Class-E driven 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 (AGC), Noise-reduction (NR), Voice-triggered Xmit (VO1X), RX Attentuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter.

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

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

- Open source firmware, built with Arduiino IDE; allows experimentation, new features can be added, contributions can be shared via Github, software-complexity: 2000 lines of code

- Software-based VO 1 X 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 CAT 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)

- Fully digital 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)

- Fully digital and software-based SDR receiver-stages (optionally): samples I/Q (complex) signal from Quadrature Sampling Detector digital mixer, and performs a 90-degree phase-shift mathematically in software (Hilbert-transform) and cancels out one side-band by adding them

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

- Receiver Noise floor MDS: –135 dBm at 28MHz (in 200Hz BW)

- Receiver Front-end selectivity: steep -45dB/decade roll-off +/-2kHz from tuned-frequency

- Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB

- CW decoder, Straight/Iambic-A/B keyer

- VFO A/B + RIT and Split, and corresponding relay band-filter switching via I2C

- CAT support (TS480 subset), possibility to stream audio, keys, display-text over CAT

- Probably the most cost effective and easy to build standalone - - - -

- SDR/SSB transceiver that you can find. Very much simplifies the original QCX circuit (i.e. 50% less components to install, no complex transformer windings, no alignment procedure) and more versatile in use.
