Has reserved pads for various upgrades, which can be used as a template for DIY upgrade learning, it also can quickly change the QRP and CW frequency and support CW sidetone volumes adjustment. It can reach 8 gears of 3-5w power, and reserve the necessary sot-223 and to-220 pads for upgrades. High Emission Efficiency: The efficiency of 80m/60m/40m/30m/20m is greater than 80%, the efficiency of 17m is greater than 70%, and the efficiency of 15m/10m is greater than 60%.
DSP functions: Automatic Gain Control (AGC), Noise Reduction (NR), Xmit Voice Trigger (VOX), RX Attenuator (ATT), TX Noise Gate, tx unit control, volumes control, dbm/s meter. Open source firmware and allows experimentation, new features can be added, contributions can be shared via github, software complexity is 2000 lines of code. Software-based VOX that can be used as quick Full Break-In (QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes (no PTT interface required), external PTT output/PA control with TX-delay.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). Power: 13.8V (1.5A Max). Adapter: EUPlug, USA Plug (Optional). Power supplys mode: Battery (NOT incldued) or external power.
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 ranges: 20kHz offset 123dB, 2kHz offset 78dB. Package size: 180 120 80mm / 7.1 4.7 3.1in. Package weight: 520g / 1.1lb.
