Description:
RX888 direct sampling 16bit SDR receiver, maximum 64M real-time bandwidth, VHF/UHF support up to 1.8GHz, maximum real-time bandwidth 8M, USB3.0 connected to a computer for use. Through the optimization of proprietary software and firmware, the requirements for computer performance have been greatly reduced. Re-optimize the design of pcb, the clock and phase-locked loop are shielded independently by shielding cover. The spectrum is clean and there is no local oscillator interference. Looking at the frequency spectrum of the last picture, it is clear whether there is spurious interference at a glance. All use LDO power supply, the whole machine 7 LDO power supply, linear power supply eliminates the interference caused by DCDC. It uses a large vacuum KDS VCXO crystal oscillator, and is designed with a potentiometer to fine-tune the frequency deviation. It is not a cheap ordinary crystal as a clock. Adding a 20dB differential low-noise amplification LNA to the ADC front end can effectively improve the medium wave sensitivity and improve the receiving performance under the small-sized antenna. The re-adjusted shortwave LPF low-pass filter, the bandwidth is adjusted to 64M, and the latest proprietary software supports direct sampling of shortwave 64M. Software extio.dll redesign, excellent UI and rich setting items, support HF and VHF/UHF antenna bias power supply BIAS-T switch, HF three gears 0db, -10db, -20db attenuation ATT, and VHF LNA And VGA settings, support global bandwidth settings. HDSDR perfect support, sdrconsole official adaptation support.
