USDX Transceiver 8-band Multimode + Mini-ANT 20W QRP Shortwave Antenna 5-55MHz. Using IRF series launch tube, durable – Can be used by connecting the antenna (M seat) – 8 bands. Power standing wave digital display! 10W max when use extral 13.8V power supply, not all bands can reach 10W – Dimensions: 76 x 46 x130mm/3 x 1.8 x 5.1 – Provide ft8 option connector later – Use TCXO for KDS. Accuracy 0.5PPM (1PPM per year) – Aluminum shell laser marking – All-aluminum knobs! Translucent silica gel button (receive green, emit red). 99MHz – Open source firmware, built in for Arduino IDE; allows experimentation, can add new functions, can share contributions through Github, software complexity: 2000 lines of code – Software-based VOX can be used as a fast full invasive (QSK and semi-QSK operation), or to assist in running in digital mode (without CAT or PTT interface) for RX/TX switching, external PTT output with TX/PA control-delay – Simple installation modification with 8 component changes and 8 wires – Lightweight, low-cost transceiver: Thanks to EER transmitter E-level, it has high power efficiency (no bulky heat sink required), and simple design (no need for complex balanced linear power amplifiers) – SSB transmitter stage based entirely on digital and software: By controlling the phase of the SI5351 PLL (via the tiny frequency change of I2C over 800kbit/s) and the amplitude of the PA (via the PWM of PWM) to sample the microphone input and reconstruct the SSB signal. PA key shaping circuit – Fully digital and software-based SDR receiver stage (optional): sample the I/Q (complex) signal from the quadrature sampling detector digital mixer, and perform a 90-degree phase shift in the software (Hilber transform) and eliminate one by adding sidebands – Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB) – Receiver noise level MDS: -135 dBm (200Hz BW) at 28MHz – Receiver front-end selectivity: steep tuning frequency -45dB / ten times roll-off +/- 2kHz – Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB – CW decoder, straight/Iambic-A/B keyer – VFO A/B + RIT and and Split, and switch the corresponding relay band filter through I2C – CAT support (TS480 subset), you can stream audio, press keys, and display text through CAT – This is probably the most cost-effective and easy to build standalone SDR/SSB transceiver. Great simplification Simplifies the original QCX circuit (that is, reduces the installation components by 50%, reduces the installation components by 50%, does not require complex transformer windings, and does not require alignment procedures), and is more versatile. Charge: Charging port of the built-in lithium battery and you can only use the supplied charger! It is forbidden to use other chargers! – Switch: OFF to shut down. BAT: Built-in battery power supply. 13.8: External power supply – DC13.8V/3A: External power supply port – KEY: automatic key body connection (A, B, single key) – PA: External power amplifier, PTT signal – MIC: External microphone port – UART: Serial communication port (command compatible with TS-480) – SPK: External speaker. Adjustable frequency: 5MHz-55MHz for sending and receiving VSWR less than 1.5 at 7MHz/10MHz/14MHz/21MHz Power: 20W FM 76mhz-108mhz reception Can receive UHF VHF frequencies. With transmitting assistance funciton Adjust frequency via its knob; and the band switch selects the short-wave high and low bands Stretched size 140cm/55.1 (including tuner). Made of stainless steel Unstretched size around 30cm/11.8 (including tuner). Tuner size 10 x 3 x 3cm/3.9 x 1.2 x 1.2 (LxWxT) Top with M4 male connector. Output M male or BNC male connector. 1 x QRP SSB/CW transceiver 1 x Power adapter 1 x Mic 1 x Tuner 1 x Antenna. Walton, KY, 41094, US. We believe our items are so outstanding.
