Note: if you choose the option that is Handheld Mic Only, it means it just a. 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.

Features: - Using IRF series launch tube, durable - Can be used by connecting the antenna (M seat) - 8 bands. 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 - All-aluminum knobs! 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 Port Introduction: - 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 Package Included: - 1 x Set of Transceiver. Usually it cost about 35USD-50USD. If you receive defective item, please kindly notify us within 14 days.
