- 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 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)
Function List:
- , 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, : 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 ity: 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
- 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 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 (): sample the I/Q () 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, //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 transformer windings, and does not require alignment procedures), and is more versatile
