USDX+ Transceiver Shortwave HF SSB QRP 3W-5W All Mode 8 Band Built-in Battery

Description: Product OverviewUSDX+ Transceiver Shortwave HF SSB QRP 3W-5W All Mode 8 Band Build in BatteryDetail USDX/QCX-SSB GitHub:github.com/threeme3/QCX-SSB/tree/feature-rx-improvedDescription:This is a shortwave QRP SSB/CW transceiver. Build in battery makes it easy to carry for outdoor use. It boasts a built-in 4000mAh lithium battery, a 1602N LCD screen, a built-in speaker. It supports connection to a PC and uses FT8, JS8, FT4 and other digital mode software control, and supports CW automatic decoding.Features:- 8 bands cover 80m/60m/40m/30m/20m/17m/15m/10m- Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance- Whether using internal battery or external 13.8v power supply, it can reach 3-5W power in 8 bands, and reserve the SOT-223 and TO-220 package pads required for upgrading- High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 80%, 17m efficiency is higher than 70%, 15m/10m efficiency is higher than 60%- High-precision KDS brand TCXO, frequency accuracy is better than 1PPM, frequency stability is better than 0.5PPM- Ultra-small size: 83*38*124mm (excluding protruding parts)- Abundant interfaces (CAT, PTT OUT, MIC/KEY, K-head microphone)- All LPF parts use 100V C0G/NP0 capacitors- Use original genuine Omron magnetic latching relays- Use op amp chip with lower noise than LM4562- Built-in speaker with cavity- Built-in 11.1v (12.6v) lithium battery- BNC antenna interfaceList of Functions:- 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: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband- DSP features: Automatic Gain Control (AGC), Noise-reduction (NR), Voice-triggered Xmit (VOX), RX Attenuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter- SSB opposite side-band/carrier suppression 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 Arduino IDE; allows experimentation, new features can be added, contributions can be shared via Github, software-complexity: 2000 lines of code- Software-based VOX 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 I2CCAT support (TS480 subset)Package Included:- 1 x Host USDX+- 1 x Mic- 1 x ChargerShipping PolicyPayment MathordReturns PolicyShipping Policy1.Items are shipped from china.we will send out within 1 bussiness day after receive the payment. 2.We only ship to ebay confirmed address.
