Describe:
* Brand new and high quality
* Made of high quality materials,
* This is a shortwave QRP SSB/CW transceiver. Ultra-small size is easy to carry and suitable for outdoor use. It has a 1602N LCD screen and built-in speakers. Support connection to PC and use digital mode software control such as FT8, JS8, FT4, etc., and support CW automatic decoding.
Feature:
* 8 frequency bands: 3.5Mhz～3.9MHz, 5351.5-5366.5kHz, 7MHz～7.3MHz, 10.1MHz～10.150MHz, 14MHz～14.350MHz, 18.068MHz～18.168MHz, 21MHz～21.450MHz and 28MHz～29.700MHz
* Excellent PCB layout design, in line with high-frequency circuit design principles, to ensure excellent performance
* Regardless of using an external 13.8v power supply, the 8-band can reach 3-5W power, and reserve the SOT-223 and TO-220 pafor CKage pads required for upgrading
* High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 80%, 17m efficiency is higher than 70%, 15m/10m efficiency is higher than 60%
* KDS adopts high-precision TCXO, the frequency accuracy is better than 1PPM, and the frequency stability is better than 0.5PPM
* Extra small size: 83 x 38 x 124mm/3.3 x 1.5 x 4.9" (not including protrusions)
* Abundant interfaces (CAT, PTT OUT, MIC/KEY, K head microphone)
* All LPF parts use 100V C0G/NP0 capacitors
* Use original magnetic latching relay
* Use op amp chip with lower noise than LM4562
* Built-in cavity speaker
* BNC antenna interface
Function list:
* Simple, fun and versatile QRP SSB HF transceiver with embedded for DSP and USDR functionality;
* EER Class E driven SSB emitter stage

* for DSP filter: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband
* for DSP Functions: Automatic Gain Control (AGC), Noise Reduction (NR), Voice Trigger Xmit (VOX), RX Attenuator (ATT), TX Noise Gate, TX Drive Control, Volume Control, dBm/S Meter
* SSB to Sideband/Carrier Suppression Transmit: Better than -45dBc, IMD3 (Dual Tone) -33dBc, Receive: Better than -50dBc
* Multi-band support, continuously adjustable via 160m-10m band (and performance loss from 20kHz to 99MHz)
* Open source firmware, built using 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 insert (QSK and half QSK ) or RX/TX switching for assist in digital mode (no CAT or PTT interface required), external PTT output/PA control TX delay
* Simple installation modification with 8 component changes and 8 wires
* Lightweight, low cost transceiver design: due to EER transmitter Class E, it is energy efficient (no bulky heat sink required) and simple to design (no complex balanced linear power required)
* All-digital and software-based SSB transmit stage: Sampling microphone input and reconstructing SSB signal by controlling the phase of SI5351 PLL (via tiny frequency change over 800kbits/s I2C) and amplitude of PA (via PWM) PA key shaping circuit)
* All-digital and software-based SDR receiver stage (optional): samples I/Q (complex) signals from quadrature
* Sampling the detector digital mixer and mathematically performing a 90 degree phase shift in software (Hilbert transform) and canceling out one sideband by adding them
* Three independently 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: +/-2kHz steep -45dB/decade roll-off from tuned frequency
* Blofor CKing dynamic range: 123dB offset at 20kHz, 78dB offset at 2kHz
* CW Decoder, Straight/Iambic-A/B Keyer
