– MIC: External microphone port
– UART: Serial communication port (command compatible with TS-480)
– SPK: External speaker
Function List:
– 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
– Full mode support: USB LSB CW AM FM
– 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 (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..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 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
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! Translucent silica gel button (receive green emit red)
