Usdr usdx+ Plus V2 8 Band SDR Full Mode HF Ham Radio SSB QRP Transceiver V1. 5W 8-Band USDX USDR HF QRP SDR Transceiver SSB/CW Transceiver DSP Mic Charger V1. It has 1602 screen, built-in battery, equipped with charger, built-in microphone, built-in speaker!It can be connected to an auto key and can be cw decoded. Characteristics: -Using Osmo series launch tube, durable -Can be used by connecting the antenna (M seat) -8 bands. 13.8v 10w maximum external power! Built-in 12.6v battery -Dimensions: 76x46x130mm/3x1.8x5.1 -Provides FT8 option connector later -Use tcxo for kds. Accuracy 0.5ppm (1ppm per year) - Aluminum shell laser marking -Fully aluminum buttons! 99mhz performance loss -Open source, integrated firmware for Arduino IDE; allows experimentation, can add new functions, can share contributions via github, software complexity: 2000 lines of code -Software based VOX can be used as a quick and full raid (QSK and Semi-QSK operation), or to assist in running in digital mode (no cat or ptt interface) for rx/tx switching, external delayed ptt output control tx/pa -Simple installation modification with 8 component changes and 8 wires -Lightweight and cost-effective transceiver: thanks to the level and eer transmitter, it has high energy efficiency (no bulky heat sink needed) and simple Design (no complex balanced linear power amplifiers required) -SSB transmitter stage entirely based on digital and software: by controlling the phase of the PLL SI5351 (through the small frequency shift of I2C above 800kbit/s) and the amplitude of the PA (through the PWM of PWM) to sample the microphone input and reconstruct the ssb signal. Pa key shaping circuit -Software-based, all-digital SDR receiver stage (optional): samples the I/Q (complex) signal from the digital mixer from the square sampling detector, and perform a 90 degree phase shift in the software (hilber transform) and eliminate one by adding sidebands -Three independently switchable analog front receiver faders (0db, -13db, -20db, -33db, -53db, -60db, -73db) - MDS receiver noise level: -135 dbm (200hz bw) to 28mhz - Receiver front selectivity: Steep tuning frequency -45db/ten times roll-off/-2khz - Lock dynamic range: 20khz offset 123db, 2khz offset 78db - CW decoder, straight/iambic-a/b keyboard -Vfo a/b scrit and split, and switch the corresponding relay band filter via i2c -Support for cat (TS480 subset), you can stream audio, press keys and display text through cat -This is probably the most economical and easiest to build standalone SDR/SSB transceiver. Great simplification simplifies the original QCX circuit i.
Reduces installation components by 50%, reduces installation components by 50%, does not require complex transformer windings and does not require alignment procedures, and is more versatile Port introduction: -Charge: Built-in lithium battery charging port and you can only use the charger provided! It is forbidden to use other chargers! -Switch: off to turn off. Bat: Built-in battery power supply.
