It is with internal mic, charger and internal battery. 3.5-30mhz Below 3.5MHz is not supported. This is a shortwave QRP SSB/CW transceiver. It boasts 1602 screen, built-in battery, equipped with charger, built-in mic, built-in speaker! It can be connected to an automatic key, and can be decoded by cw. Using IRF series launch tube, durable. Can be used by connecting the antenna (M seat). Power standing wave digital display! External 13.8v maximum power 10w! Built-in 12.6v battery. 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. Translucent silica gel button (receive green, emit red). Simple, interesting and versatile QRP SSB HF transceiver with embedded DSP and SDR functions. EER E-level driven SSB launch stage. 13.8V power supply provides about 10W PEP SSB output. DSP filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband. DSP function: automatic 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/S-meter. SSB reverse sideband/carrier suppression transmission: better than -45dBc, IMD3 (two tones) -33dBc, reception: better than -50dBc. Multi-band support, continuously adjustable in the 160m-10m frequency band and performance loss from 20kHz.. 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. 1 x Set of Transceiver. Usually it cost about 35USD-50USD. Thanks for your understanding. If you receive defective item, please kindly notify us within 14 days.
