SDR-трансивер HF QRP 8-диапазонный SSB CW

Function: 1. Reliable Operation: The pocket-sized 8-band SSB CW QRP transceiver designed with built-in lithium battery, built-in microphone, PTT button and extremely low current consumption RX, is a good partner for SOTA, POTA or other portable activities. 2. Better Design: This QRP SSB CW shortwave transceiver features a large screen, built-in battery, charger, built-in microphone and speaker. It can be connected to an automatic button. It can also be a decoding of CW encoding. 3. IRF Launch Tube: With the IRF series heavy-duty launch tube, it can be used to connect the antenna which is on the base of the instrument. 4. Simple structure: all aluminum buttons and translucent silicone buttons, the original qcx transformer circuit is greatly simplified, and the installation components are reduced by 50%. No complicated windings. There is no wiring procedure. 5. High Efficiency: High energy efficiency and simple design, with eer electronic level transmitters, also very convenient to carry.

Specification: Item type: SDR transceiver Material: aluminum alloy Battery: 1 x 3500mAh 605585 lithium battery, delivery with built-in battery. Function: Radio transceiver: QRP SSB HF transceiver with built-in DSP and SDR functions. Launch: SSB startup stage driven by EER E level. Output: 13.8V power supply provides PEP SSB output power of approximately 10W. Full mode support: USB, LSB, CW, AM, FM DSP filter: frequency response 4000, 2500, 1700, 500, 200, 100, 50Hz. DSP Function: Auto Gain Control (AGC), Noise Reduction (NR), Voice Trigger, Voice Trigger Xmit (VOX), RX Attenuator Attenuator (ATT), TX Noise Gate, TX Driver Control, Volume Control, dBm Meter S SSB Reverse Band side and carrier attenuation transmission: better than -45dBc IMD3 two tones: -33dBc, reception: better than -50dBc. Multi-band support: stepless adjustment in the 160m-10m frequency band and loss of efficiency from 20kHz to 99MHz. Open source firmware, embedded for IDE: allows experimentation, can add new features, can share contributions via Github, software complexity: 2000 lines of code. Features: Software-based VOX can be used as a fast, fully invasive (QSK and semi QSK operation) or to support digital operation (no CAT or PTT interface) for RX/TX switching, external PTT output with TX/PA control delay Installation: Simple installation modification with 8 component changes and 8 wires. High Efficiency: With E-level EER transmitter, it has high power efficiency (doesn't require a large heat sink) and simple design (no need for complex balanced linear power amplifiers). SSB transmitter scene based entirely on digital technology and software: by controlling the phase of the SI5351 PLL (via a slight variation of the I2C frequency above 800 kbit/s) and the amplitude of the PA (via PWM PWM) to sample the microphone input and reconstruct the SSB signal. PA key shaping circuit). Full digital and software based SDR receiver stage (optional): sample the I/Q (complex) signal from the digital quadrature sampling detector mixer and perform a 90 degree phase shift in the software (Hilber transform) and eliminate them by adding sidebands. 3 independent switchable analog front receiver attenuators: 0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB MDS receiver noise level: -135 dBm (200 Hz BW) at 28 MHz. Front end selectivity: Tuning frequency steep -45dB, 10x drop /- 2kHz Dynamic range locking: 20kHz offset 123dB, 2kHz offset 78dB. CW Decoder: Simple, Iambic-A, B keyer, VFO A/B RIT and Split and switch the corresponding relay band filter via I2C TS480 subset CAT support: You can stream audio, press keys and display text via CAT. SDR SSB transceiver: A great simplification simplifies the original QCX circuit, i.e. reduces the number of installation components by 50%, does not require complicated transformer windings and does not require setup procedures.
