List of Functions:
- Simple, fun and versatile QRP SSB HF transceiver with embedded DSP and SDR functions;
- EER Class-E driven SSB transmit-stage
- Approximately 5W PEP SSB output from 13.8V supply
- All-Mode support: USB, LSB, CW, AM, FM
- DSP filters: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband
- DSP features: Automatic Gain Control (AGC), Noise-reduction (NR), Voice-triggered Xmit (VOX), RX Attenuators (ATT), TX noise gate, TX drive control, Volume control, dBm/S-meter
- SSB opposite side-band/carrier suppression Transmit: better than -45dBc, IMD3 (two-tone) -33dBc, Receive: better than -50dBc
- Multiband support, continuously tunable through bands 160m-10m (and from 20kHz..99MHz with loss in performance)
- Open source firmware, built with Arduino IDE; allows experimentation, new features can be added, contributions can be shared via Github, software-complexity: 2000 lines of code
- Software-based VOX that can be used as fast Full Break-In (QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes (no CAT or PTT interface required), external PTT output/PA control with TX-delay
- Simple to install modification with 8 component changes and 8 wires
- Lightweight and low-cost transceiver design: because of the EER-transmitter class-E stage it is highly power-efficient (no bulky heatsinks required), and has a simple design (no complex balanced linear power amplifier required)
- Fully digital and software-based SSB transmit-stage: samples microphone-input and reconstruct a SSB-signal by controlling the phase of the SI5351 PLL (through tiny frequency changes over 800kbits/s I2C) and the amplitude of the PA (through PWM of the PA key-shaping circuit)
- Fully digital and software-based SDR receiver-stages (optionally): samples I/Q (complex) signal from Quadrature
- Sampling Detector digital mixer, and performs a 90-degree phase-shift mathematically in software (Hilbert-transform) and cancels out one side-band by adding them
- Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB)
- Receiver Noise floor MDS: -135 dBm at 28MHz (in 200Hz BW)
- Receiver Front-end selectivity: steep -45dB/decade roll-off +/-2kHz from tuned-frequency
- Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB
- CW decoder, Straight/Iambic-A/B keyer
- VFO A/B + RIT and Split, and corresponding relay band-filter switching via I2C
CAT support (TS480 subset)
