V2 uSDR 10/15/17/20/30/40/60/80m QRP SDR SSB 8 Band HF Transceiver+LCD Display. Some buyers say that the ssb sound quality is not good. This is a historical reason. You can go to Facebook to check the discussion results. Compared with the old uSDX, the new upgraded uSDX as follows. + Move the headphone jack and the power button/microphone jack to the front panel to make it easier to connect the earphone and power button.

+ Move the buttons to the bottom of the LCD screen for a larger touch area and a more comfortable button experience. + Upgrade the built-in speaker effect, the sound is doubled! + Ultra-small shell volume, only 8338120mm shell is used, and the shell space utilization rate is as high as 87%. + PCB reserves the pads required for various upgrades, which can be used out of the box, and can be used as a blueprint for DIY upgrades and learning. + Quickly switch QRP CW frequency.

+ Support CW side tone volume adjustment. + Support CW side tone tone adjustment. Introduction: This is a shortwave QRP SSB/CW transceiver.

The ultra-small size is easy to carry for outdoor use, 1602N LCD screen, built-in speaker, support to connect to PC and use FT8, JS8, FT4 and other digital mode software control, and support CW automatic decoding. + 8 bands cover 80m/60m/40m/30m/20m/17m/15m/10m. + Excellent PCB layout design in line with high-frequency circuit design principles to ensure excellent performance. + Regardless of using internal battery or external 13.8v power supply, it can reach 3-5W power in 8 bands, and reserve the SOT-223 and TO-220 package pads required for upgrades. + 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%.

+ High-precision KDS brand TCXO, frequency accuracy is better than 1PPM, frequency stability is better than 0.5PPM. + Ultra-small size: 8338124mm (excluding protruding parts). + Abundant interfaces (CAT, PTT OUT, MIC/KEY, K-head microphone). + All LPF parts use 100V C0G/NP0 capacitors.

+ Use original genuine Omron magnetic latching relays. + Use op amp chip with lower noise than LM4562. + Built-in speaker with cavity.

SSB for sideband/carrier suppression emission: better than -45dBc, IMD3 (dual tone) -33dBc, reception: better than -50dBc - Multi-band support, continuously adjustable through 80m-10m frequency band starting from 20kHz.. 99MHz, performance loss - Open source firmware, built using Arduino IDE; allows experimentation, can add new features, can share contributions through Github, software complexity: 2000 lines of code - Software-based VOX can be used for fast full control (QSK and semi-QSK operation) or auxiliary RX/TX switching to operate in digital mode (no CAT or PTT interface required), external PTT output/PA control with TX-delay - All-digital and software-based SSB transmitter stage: By controlling the phase of the SI5351 PLL (via a small frequency change on the 800kbits/s I2C) and the amplitude of the PA (via the PWM PA key shaping circuit) - All-digital and software-based SDR receiver stage (optional): I/Q (complex) signals are sampled from the quadrature sampling detector digital mixer, and the 90-degree phase shift is mathematically performed in the software (Hill Bert transform) and cancel one by adding sidebands - Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB) - Receiver noise floor MDS: -135 dBm at 28MHz (200Hz BW) - Receiver front-end selectivity: +/-2kHz steep -45dB/decade roll-off from the tuning frequency - Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB - CW decoder, Straight/Iambic-A/B keyer - VFO A/B + RIT and Split, and the corresponding relay with filter switch through I2C - CAT support (using Kenwood TS-480 protocol).
