Mini 8 Band SSB/CW QRP Transceiver For Ham Radio, Style: Host + Hand Mi + US

Features:1. IRF series transmitter tubes, durable2. Can be used to connect the antenna (instrument base)3. Aluminum laser case marking, all aluminum buttons, translucent silicone keys4. The original qck circuit is greatly simplified, the installation components are reduced, and the complex transformer windings and wiring procedures are not needed, and the construction is easy (green and red)5. 8-band, digital display, external power supply 13.8 v 10W, built-in 12.6 V batteryFeatures list:1. Simple, interesting and versatile cxp ssb high frequency transceiver with built-in dsp and sdr functions2. Eer class e drives the ssb launch phase3. 13.8v power supply about 10w ssb pep output4. Filters: 4000,2500,1700,500,200,100,50hz passband5. Dsp functions: automatic gain control (agc) , noise reduction (nr) , voice trigger, voice trigger XMIT, attenuator rx (att) , tx noise gate, tx drive control, volume control, dbm/s-meter6. Ssb reverse sideband/carrier suppression transmission: better than -45 dbc, imd3(double tone) -33 dbc, receive: better than -50 dbc7. Multi-band support, continuously adjustable in the 160m-10m frequency range (loss of 20khz performance)99mhz8. Open source firmware, built into IDE; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines of code9. V-based software can be used for fast and complete rogue operations (qsk and semi-qsk) , or to assist execution in digital mode (without cat or ptt interface) for rx/tx switches with tx/pa delay control, external ptt output-simple installation and modification, 8 component changes and 8 lines10. Lightweight, low-cost Transceiver: eer electronic level transmitter, which has high power efficiency (without the need for a large radiator) and simple design (without the need for complex balanced linear power amplifier)11. SSB transmitter phase is completely digital and software-based: controls the phase of the SI5351 PLL (via small I2C frequency changes over 800 kbit/s) and the amplitude of the PA (via pwm to pwm) to test the microphone input and reconstruct the SSB signal. Key shaping circuit PA)12. All-digital and software-based SDR receiver level (optional) : sampling of I/Q signals (plural) from a digital mixer with an orthogonal sampling detector, and in which the implementation of the 90-degree phase shift (Hilber transform) software and by adding remove sideband13. Three switchable analog governors independent of the front-end receiver14. MDS receiver noise level: -135 dbm (200 hz bw) at 28 mhz15. Pre-receiver selectivity: steep frequency adjustment -45 db/10 rollover16. Blocking dynamic range: 20khz offset 123db, 2khz offset 78db17. CW decoder, corresponding relays with filters switched via i2c-Cat support (TS480 subset) , you can stream audio, keystrokes, and display text through CATPort description:1.
