Function: 1. Remove the headphones and the power button/microphone jack to the front panel, convenient to connect the headset and the power button 2. Move the keys to the bottom of the LCD screen for a larger touch area and a more comfortable keystroke experience 3. Upgrade the built-in speakers to double the sound 4. PCB to reserve a variety of upgrades required pad, out of the box, can be used as a DIY upgrade learning template 5. Change the QRP CW frequency quickly 6. Support CW side volume adjustment 7. Support CW side tones 8. This is a shortwave QRP SSB/CW transceiver. Ultra-small size for portable outdoor use, 1602n LCD screen, built-in speakers, support to connect computers using FT8, JS8, FT4 and other mode software control digital, support CW automatic decoding
Features: 1. 8 tracks covering 80M/60m/40m/30M/20m/17M/15m/10m 2. PCB layout design in line with high frequency circuit design principles to ensure excellent performance 3. Power can achieve 8-stop 3-5w, and reserve the necessary sot-223 and To-220 pack pad for upgrading 4. High launch efficiency 7. KDS high precision tcxo brand, frequency accuracy above 1ppm, frequency stability above 0.5ppm 8. Ultra-small size: 88x39x124mm (without bulge) 9. Rich interfaces (cat, ptt out, mic/key, k-head mic) 10. All LPF components use 100v c0g/np0 capacitors 11. Using op-amp chips are lower than those of lm4562 noise 12. A built-in speaker with a cavity 13. BNC antenna interface
Explanation: 1. Support full mode: usbãÂÂlsbãÂÂcwãÂÂamãÂÂfm (ssb mode reception effect is good, but the transfer effect is poor. AM and FM mode is free, the effect is not good) 2. Filter DSP filter: 4000,2500,1700,500,200,100,50 Hz passband 3. Function DSP function: automatic gain control (AGC) , noise reduction (NR) , XMIT Voice Trigger (Vox) , RX attenuator (Att) , TX Noise Gate, TX unit control, volume control, DBM/S instrument 4. Sidebar/carrier suppression SSSSB emission: superior to -45dbc, IMD3(dual tone) -33dbc, receiver: superior to -50dbc 5. Support for multi-band support, in the 80m frequency range of continuous adjustable 10m (from 20khz. 99mhz, loss performance) 6. Open source firmware, built using Arduino IDE; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines based on 7. The software vovovox code can be used for fast complete control (qsk and semi-qsk operations) or RX/auxiliary switch TX to be used in digital mode (no cat or PTT interface is required) 8. The PTT/PA output is externally controlled by the all-digital tx-delay stage and the software-based SSB stage transmitter: the phase of sill SI5351 is controlled (by a small frequency change i2c at 800 kbits/s) and the PA amplitude is controlled (by a pwm pa key shaping circuit) 9. Software-based all-digital SDR receiver level (optional) : sampling of I/Q (complex) signals from a digital mixer with an orthogonal sampling detector, and mathematically perform a 90-degree phase shift (David Hilbert transform) in the software by adding an Atten sideband 10. Three independent switchable analog pushers (0db, -13 db, -20 db, -33 db, -53 db, -60 db, -73 db) from the front receiver 11. Receiver background noise mds: -135 DBM at 28 mhz (200 hz bw) 12. Receiver receiver front-end selectivity: +/-2 khz scrolling at steep 45 db/decade tuning frequency 13. Blocking dynamic range: 20khz offset 123db, 2khz offset 78db 14. CW decoder, direct/iambic-a/B keying 15. VVFO A/B + RIT and split, and the corresponding relays pass through i2c 16. The CAT supports cat with a filter switch (using the kenwood TS-480 protocol)
