SDR6

ACTUAL LO FOR THIS VERSION: 28.8MHZ

100KHz-1.7GHz full band RTL-SDR receiver, can be connected to PC, Android phone and other devices using SDR software to receive electromagnetic wave support AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation. Can listen to medium wave, short wave, FM radio, short wave single side band communication, walkie talkie call.

FM Radio :87MHz-108MHz, select WFM.

Medium wave broadcasting 526.5kHz~1606.5kHz, AM.

Short wave broadcast :3MHz~30MHz, AM.

Airport Tower Frequency :118MHz~135.975MHz, AM.

Walkie Talkie Frequency.

VHF:136MHz-174MHz in NFM format

UHF:40OMHz-470MHz in NFM standard.

Amateur radio communications: short-wave single sideband: 1OMHz commonly used below the lower single sideband LSB; 1OMHz commonly used above the upper single sideband USB.

Ultra shortwave radio: NFM standard, frequency 50-54MHz, 144-148MHz, 430-440MHz.

Features:

Short and medium wave directly to the antenna received signal input to the digital-to-analog conversion chip, to solve the use of frequency converter brought about by the signal loss, noise, waveform clutter, bias frequency, and other issues, so that the sensitivity is improved, and the waveform display is clear and complete, high-resolution, showing the actual frequency.

SA6 SDR-V4 Blog RTL SDR V4 R828D RTL2832U 1PPM TCXO SMA RTLSDR Software Defined Radio with Multipurpose Dipole Antenna

SDR-V2 radio receivers are RTL-SDR receivers based on RTL2832U chips, but they are equipped with different Tuners:

Equipped with FC0012 Tuner, supporting the 22-948.6MHz frequency band;

Equipped with FC0013 Tuner, the frequency band is expanded to 22-1100MHz, and supports L-band input.

Note:

1. RTL-SDR V2 cannot receive shortwaves because the RTL2832U chip of RTL-SDR itself does not directly support shortwave reception, because it lacks the direct downconversion function of the HF frequency band (below 24 MHz), so RTL-SDRV2 cannot receive shortwaves due to hardware limitations.

If you want to receive shortwave, it is recommended to choose RTL-SDR V4.

RTL-SDR has a rich supporting software ecosystem, covering multiple platforms such as computers, tablets, and mobile phones.

Real-time sampling rate: approximately 2.4 MS/s (million samples per second) Actual stable value may be slightly lower).

I/Q mode: supports complex sampling (orthogonal downconversion).

Resolution: ADC Bits: 8 bits (RTL2832U built-in) with limited dynamic range for entry-level applications.

Peculiarity:

1. Interface: USB 2.0: Depends on computer processing signals (may be limited by USB bandwidth).

2. Cost-effective entry-level SDR, compared with professional SDR equipment (such as HackRF, USRP), the price is low, suitable for novices to learn radio technology.

3. Compatible with mainstream SDR software (SDR#, GORX, HDSDR, CubicSDR, etc.), no additional driver required.

4. Open source ecological support, the global developer community provides rich software support, such as: SDR# (Windows platform, easy to use, GORX (Linux/macOS, supports spectrum analysis), rtl_433 (decoded 433MHz sensor signal), dump1090 (aviation ADS-B signal decoding), etc.

5. Low power consumption and portable design, USB powered, no external power supply required.
