WHAT IS SOFTWARE DEFINED RADIO (SDR)? 

In traditional hardware radios, the mathematical operations required to decode and process radio signals are performed using analogue circuitry. Recently, computers have become powerful enough to perform the required mathematical calculations in software, hence the term software defined radio. This has led to advanced radios that previously required complicated analogue hardware now being able to be implemented easily in software. This has reduced the cost of advanced radio capabilities such as wideband tuning and waterfall displays.

WHAT IS THE RTL-SDR?

The RTL-SDR is an extremely cheap software defined radio which is based on DVB-T TV (Digital HD TV) USB receiver dongles that have the RTL2832U chip in them. It was discovered by hardware hacker Eric Fry, Linux driver developer Antti Palosaari and the Osmocom team who were developing their own SDR that the RTL2832U chip had a mode which enabled SDR. Today, by using custom software drivers, a commonly used cheap RTL2832U can then be turned into a sophisticated SDR with features that would have until recently cost in the hundreds to thousands of dollars. Of course, the performance of these dongles will not match a dedicated SDR, but they perform extremely well for the price, and almost all hobbyist projects that can be done with expensive radios or SDRs can also be done with the rtl-sdr. A wideband SDR opens up many interesting possible projects and avenues to explore. Some applications of the RTL-SDR include the following, some of which will be discussed in more depth in the project tutorials chapter.

The set includes

SMA Straight Antenna Adapter

--- SMA male to female UHF,

 --- SMA male to female BNC

1x main unit

1x USB cable

1x Storage Box

Direct sampling RTL-SDR TECHNICAL SPECIFICATIONS

·         Fully assembled and ready to use

·         Uses RTL2832U+R820T2   chip set.

[the  R820T2   tuner has slightly better sensitivity than the R820T and also works better at frequencies around 1.5 GHz.  100% compatible with software for the older R820T.]

·         100KHz to 1766MHz, operating frequency

·         1 PPM temperature compensated oscillator (TCXO)

 [Accurate tuning and almost zero temperature drift (2 PPM initial offset, 1 PPM temperature drift)]

·         Covers all HF amateur bands

·         Covers VHF & UHF bands from 24-1766MHz

·         Up to  3.2 M  Sample rate. (~2.8 MHz stable)

·         Receiver modes AM, NFM, FM, DSB, USB, LSB and CW

·         HF Shortwave Q branch direct sampling

·         Note: depends upon the SDR software used with the receiver

·         8-bit ADC giving ~50 dB dynamic range

·         50  Ohm input impedance

·         SMA golden antenna connectors It is also more durable and has          lower insertion losses.

·         Aluminum enclosure screened panels

·         Small size board

·         Freeware software

·         Independent antenna inputs for Shortwave and VHF

·         USB computer connection  ( mini usb) Powered by common USB

·         All specifications subject to change without notice

Receiving LF/MF/HF (0 - 30 MHz)

The HF band antenna must be connected to the Ant input port

signal receiving HF band needs to meet the HF Antennas such as Long Wire, Random Wire, Dipole etc.. To have a good effect need matching antenna.

The program of SDR # with RTL configured to direct sampling of the signal Q, as shown in the following figure

Operation  on VHF and UP:

The UV band antenna must be connected to the Ant input port

By default the RTL-SDR’s gain is set to zero. Increase this gain by moving the RF Gain slider up, or by turning on Tuner AGC.
