  • RTL-SDR V4 (incl. Dipole Antenna Kit)

    RTL-SDR RTL-SDR V4 (incl. Dipole Antenna Kit)

    8 reviews

    RTL-SDR is an affordable dongle that can be used as a computer-based radio scanner for receiving live radio signals between 500 kHz and 1.75 GHz in your area. The RTL-SDR V4 offers several improvements over generic brands including use of the R828D tuner chip, triplexed input filter, notch filter, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit, improved power supply, and a built in HF upconverter. RTL-SDR V4 comes with the portable dipole antenna kit. It is great for beginners as it allows for terrestrial and satellite reception and easy to mount outdoors and designed for portable and temporary outside usage. Features Improved HF reception: V4 now uses a built-in upconverter instead of using a direct sampling circuit. This means no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Like the V3, the lower tuning range remains at 500 kHz and very strong reception may still require front end attenuation/filtering. Improved filtering: The V4 makes use of the R828D tuner chip, which has three inputs. The SMA input has been triplexed input into 3 bands: HF, VHF and UHF. This provides some isolation between the 3 bands, meaning out of band interference from strong broadcast stations is less likely to cause desensitization or imaging. Improved filtering x2: In addition to the triplexing, the open drain pin on the R828D can be also used, which allows to add simple notch filters for common interference bands such as broadcast AM, broadcast FM and the DAB bands. These only attenuate by a few dB, but may still help. Improved phase noise on strong signals: Due to an improved power supply design, phase noise from power supply noise has been significantly reduced. Less heat: Another advantage of the improved power supply is low power consumption and less heat generation compared to the V3.

  • SDR Hands - on Book - Elektor

    Elektor Publishing SDR Hands-on Book

    The short-wave technique has a very particular appeal: It can easily bridge long distances. By reflecting short-wave signals off the conductive layers of the ionosphere, they can be received in places beyond the horizon and therefore can reach anywhere on earth. Although technology is striving for ever higher frequencies, and radio is usually listened to on FM, DAB+, satellite or the Internet, modern means of transmission require extensive infrastructure and are extremely vulnerable. In the event of a global power outage, there is nothing more important than the short-wave. Amateur radio is not only a hobby, it’s also an emergency radio system! Elektor’s SDR-Shield is a versatile shortwave receiver up to 30 MHz. Using an Arduino and the appropriate software, radio stations, morse signals, SSB stations, and digital signals can be received. In this book, successful author and enthusiastic radio amateur, Burkhard Kainka describes the modern practice of software defined radio using the Elektor SDR Shield. He not only imparts a theoretical background but also explains numerous open source software tools.

    RTL-SDR RTL-SDR Broadcast FM Band-Stop Filter (88-108 MHz Reject)

    1 review

    2 in stock

    This filter rejects signals between 88-108 MHz with around 50 dB or more attenuation. A broadcast FM band-stop filter is very useful for use with SDRs as in some areas broadcast FM signals can be so strong that they overload the SDR, causing very poor performance in other bands. You can tell if this is the case for you if you see images of BCFM stations or interference that looks like a WFM signal at other frequencies when you turn up the gain. The filter is based on a simple 7th order Chebyshev design. The 3 dB roll off is at 76 MHz and 122 MHz. 88 MHz is attenuated by almost 60 dB, and 108 MHz is attenuated by 45-50 dB. Outside of the pass band the insertion loss is practically zero below 500 MHz, less than 0.5 dB from 500 MHz – 1 GHz, and below 1.5 dB between 1-2 GHz. Between 2-3 GHz performance degrades slightly, but insertion loss remains below 1.5 dB for most frequencies. The filter can also pass up to 80 mA of DC current (probably can do more) and has negligible DC resistance. The filter comes in a 28 x 28 x 13 mm aluminum enclosure and uses female SMA connectors on each end. Included in the package is also a SMA male to SMA male straight barrel adapter.

  •  -14% KrakenSDR - Five - channel Software Defined Radio (based on RTL - SDR) - Elektor

    KrakenRF KrakenSDR 5-ch SDR (based on RTL-SDR)

    1 review

    KrakenSDR is a phase-coherent software-defined radio with five RTL-SDRs KrakenSDR is a 5-channel, RX-only, software-defined radio (SDR) based on the RTL-SDR and designed for phase-coherent applications and experiments. Phase-coherent SDR opens the door to some very interesting applications, including radio direction finding, passive radar, and beam forming. You can also use KrakenSDR as five separate radios. KrakenSDR is an upgraded version of the previous product, KerberosSDR. It provides a fifth receive channel, automatic phase-coherence synchronization capabilities, bias tees, a new RF design with cleaner spectrum, USB Type-C connectors, a heavy-duty enclosure, upgraded open source DAQ and DSP software, and an upgraded Android app for direction finding. RTL-SDR KrakenSDR makes use of five custom RTL-SDR circuits consisting of R820T2 and RTL2832U chips. The RTL-SDR is a well-known, low-cost software-defined radio (SDR), but throw five units together and using them on the same PC will not make them 'phase coherent;' each one will receive signals at a slightly different phase offset from the others. This makes it difficult or impossible to achieve a high degree of precision when measuring relationships between signals that arrive at different antennas. To achieve phase coherence, KrakenSDR drives all five RTL-SDR radios with a single clock source, and contains internal calibration hardware to allow the phase relationship between channels to be measured precisely and corrected for. Additionally, the overall design of KrakenSDR works to ensure phase stability, with care taken in the areas of heat management, driver configuration, power supply, and external-interference mitigation. Features Five-channel, coherent-capable RTL-SDR, all clocked to a single local oscillator Built-in automatic coherence synchronization hardware Automatic coherence synchronization and management via provided Linux software 24 MHz to 1766 MHz tuning Range (standard R820T2 RTL-SDR range, and possibly higher with hacked drivers) 4.5 V bias tee on each port Core DAQ and DSP software is open source and designed to run on a Raspberry Pi 4 Direction-finding software for Android (free for non-commercial use) Applications Physically locating an unknown transmitter of interest (e.g. illegal or interfering broadcasts, noise transmissions, or just as a curiosity) HAM radio experiments such as radio fox hunts or monitoring repeater abuse Tracking assets, wildlife, or domestic animals outside of network coverage through the use of low power beacons Locating emergency beacons for search-and-rescue teams Locating lost ships via VHF radio Passive radar detection of aircraft, boats, and drones Traffic-density monitoring via passive radar Beamforming Interferometry for radio astronomy Specifications Bandwidth 2.56 MHz RX Channels 5 Frequency Range 24-1766 MHz Radio Tuner 5x R820T2 Radio ADC 5x RTL2832U ADC Bit Depth 8-bits Oscillator Stability 1 PPM Typical Power Consumption 5 V/2.2 A (11 W) Enclosure Type Heavy-duty CNC Aluminum Dimensions 177 x 112.3 x 25.9 mm Weight 560 g Included 1x KrakenSDR (fully assembled and installed) with Aluminum enclosure 1x Manual Required USB Type-C cable 5 V/2.4 A USB-C power supply Antennas Raspberry Pi 4 (for computing) Android phone/tablet with mobile-hotspot capabilities (with direction finding) Downloads Wiki Android App

What is RF? What is RF used for?

Electromagnetic fields, radio waves, microwaves, and wireless signals are called radio frequency (RF) energy. RF currents are electrical currents that oscillate at radio frequencies and have unique characteristics. RF energy is all around us, and RF is used in a variety of electronics and devices, including radio and television broadcasting, cellular telephones, satellite communications, microwave ovens, radars, and industrial heaters and sealers. These are just a few examples.

What is software-defined radio (SDR), and what can you do with SDR?

In general, an electrical signal is generated by hardware components. It is quite complicated to process signals with hardware and has limitations to troubleshoot. With software-defined radio (SDR), RF communication takes place using software, which simplifies the limitations of signal processing with hardware. Instead of having to use mixers, filters, amplifiers, modulators, demodulators, and so on, SDR uses just an ADC and DAC, along with antennas, without the need for many hardware components.

The software for SDR can be used on a personal computer or an embedded system, providing a more flexible application and making it easy to troubleshoot problems. SDR is used in broadcast and amateur radio, radio astronomy, aircraft tracking and GSM network building, and many more applications. It's a good choice for many fun projects.

RTL-SDR is an affordable USB radio used to receive live radio broadcasts from a computer. Due to its popularity, users benefit from a wider variety of radio signals that just a few years ago would have cost hundreds or thousands of euros.

What does Elektor have to offer?

Elektor offers a variety of RF and SDR-related kits, such as the Elektor Raspberry Pi RTL -SDR Kit, which allows you to receive radio signals between 500 kHz and 1.75 GHz from stations using different bands, including MW/SW/LW broadcast, ISM, CB, ham radio, utility, and more. In addition, Elektor supplies its customers with telescopic antennas and magnetically mountable antennas, and much more. Browse our list to find a suitable solution for you.

What does the future hold for SDR?

The popularity of SDR solutions has been increasing since the widespread availability of 4G equipment. The prospects of upcoming technologies such as 5G, the Internet of Things (IoT), and sensor networks promise to further boost SDR . SDRs are built with more powerful FPGAs, and these applications are intended for increasingly complex tasks. As a result, FPGA tools that can manage growing amounts of data and complexity will inevitably gain popularity.
