1. Enjoy radio as stereo sound from MP3 player; Super LNA (low noise amplifier), Ultra lower voice and super strong signal receiving. 2. Very tiny, perfect hardware for smartphone,tablet to use it for travel,Camping picnic or ham radio. better to use it with our portable Ground antenna or Portable Miniwhip antenna. 3. Easy to receive HF signals (bands below 25Mhz) with simple outdoor antenna, such as long wire antenna, loop antenna, even single outdoor telescopic antenna, it can receive HF signals (below 25Mhz) very well based on excellent built-in amplifier . By the way, the more powerful antenna it is for use with, the excellent performance it will show. 4. Only ONE Integreated SMA connector for both HF 0.5Mz-25Mhz and 25Mhz -1.8Ghz, no need to switch between the two SMA input(below 25Mhz or up 25Mhz). People usually forget to switch the SMA connectors when use direct sampling mode to receive HF signals.This V3 Pro use only one SMA connectors input, and it will be switch between the shorwave and long waves signals by the built-in filter Automatically. 5. Small power consumption only; Use power high efficient conductor Type: RTL SDR This receiver has a built-in 1 ppm temperature compensation crystal [TCXO]. Make the frequency more stable and accurate. Almost zero temperature drift [initial deviation of 2 ppm, temperature drift of 1 ppm] increases the internal chip heat dissipation, making the work more stable. Using the latest RTL2832U+R820T2 program [R820T2 tuner has slightly better sensitivity than R820T, lower noise floor, and higher signal-to-noise ratio. It can work more stably at frequencies around 1.5 GHz. ]Using the Q channel on the RTL2832U to increase the direct sampling reception of the frequency of 100KHz-24MHz. Achieve full range reception of 100KHz-1.7GHz. Support XP Win7, Win8, Win10, , Android and other systems. colour:Golden Material:metal Package Contents: 1 x RTL SDR receiver Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
