PCB to reserve a variety of upgrades required pad, out of the box, can be used as a DIY upgrade learning template \u003cbr\u003e5. Change the QRP CW frequency quickly \u003cbr\u003e6. Support CW side volume adjustment \u003cbr\u003e7. Support CW side tones \u003cbr\u003e8. This is a shortwave QRP SSB\/CW transceiver. Ultra-small size for portable outdoor use, (no battery) 1602n LCD screen, built-in speakers, support to connect computers using FT8, JS8, FT4 and other mode software control digital, support CW automatic decoding \u003cbr\u003e \u003cbr\u003eFeatures: \u003cbr\u003e1. 8 tracks covering 80M\/60m\/40m\/30M\/20m\/17M\/15m\/10m \u003cbr\u003e2. PCB layout design in line with high frequency circuit design principles to ensure excellent performance \u003cbr\u003e3. Both built-in Battery and external 13.8v power supply, can achieve 8-stop 3-5w power, and reserve the necessary sot-223 and To-220 pack pad for upgrading \u003cbr\u003e4. High launch efficiency \u003cbr\u003e7. KDS high precision tcxo brand, frequency accuracy above 1ppm, frequency stability above 0.5ppm \u003cbr\u003e8. Ultra-small size: 88x39x124mm (without bulge) \u003cbr\u003e9. Rich interfaces (cat, ptt out, mic\/key, k-head mic) \u003cbr\u003e10. All LPF components use 100v c0g\/np0 capacitors \u003cbr\u003e11. Using op-amp chips are lower than those of lm4562 noise \u003cbr\u003e12. A built-in speaker with a cavity \u003cbr\u003e13.

Support full mode: usb, lsb, cw, am, fm (ssb mode reception effect is good, but the transfer effect is poor. AM and FM mode is free, the effect is not good) \u003cbr\u003e2. Filter DSP filter: 4000, 2500,1700,500,200,100,50 Hz passband \u003cbr\u003e3.

Sidebar\/carrier suppression SSSSB emission: superior to -45dbc, IMD3(dual tone) -33dbc, receiver: superior to -50dbc \u003cbr\u003e5. Support for multi-band support, in the 80m frequency range of continuous adjustable 10m (from 20khz. 99mhz, loss performance) \u003cbr\u003e6. 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 \u003cbr\u003e7. 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) \u003cbr\u003e8. 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) \u003cbr\u003e9. 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 \u003cbr\u003e10.
