Monitoring the dual receiver output with headphones is interesting. It is interesting to note the difference in interference pick-up between the two antennas and also that some signals appear on one antenna and not the other. The images show typical displays on medium wave broadcast, short wave and the last image shows an Over The Horizon Radar (OTHR) transmitting in the 20m amateur band. The receiver for the bottom waterfall uses a horizontally polarised terminated inverted V dipole. For the demonstration the receiver on the top waterfall uses a vertically polarised Fractal Vertical antenna. The images on the right show a SDR-4++ receiver using two HDSDR sessions to display each receiver channel simultaneously. Overall dimensions: 185 mm (L) x 110 mm (W) x 50 mm (H)

Receiver modes: Depends upon the SDR software used with the receiverĬonnectors: Two BNC female (RF in 50 ohms), three USB B ports, five 3.5mm stereo jacks Input IP3: +10 dBm (measured with two -20 dBm carriers with 20 kHz spacing at 14 MHz, attenuator off) Maximum frequency display: 48 kHz internal sound card, up to 192 kHz external sound card

The total dynamic range is limited by the sound card so the receiver has a socket to connect to a external 24 bit sound card if requiredģ.5mm IQ audio output from each receiver for connection to external high sampling rate sound cardsģ.5mm soundcard audio output from each receiver for headphone monitoring or connection to datamodes programģ.5mm soundcard audio output with outputs from both receivers for headphone monitoring or connection to datamodes programīuilt in a compact aluminium case 175 x 106 x 45 mm for full RF shielding

Typically 8 bit SDR dongles have 45 db and 12 bit SDR receivers have 70 dB dynamic range. RF amplifier using a NXP high linearity RF bipolar amplifier in the receiver front endĬrosstalk isolation between the receivers better than 50 dBīuilt-in 16 bit USB stereo soundcard gives 89 dB dynamic range. RF overload protection up to 150W for 10 secondsĮxtra antenna isolation when the receiver is powered down It uses two of our SDR-4+ receivers using a common oscillator so that both receivers are phase coherent for receiver diversity or radio propagation analysis using two separate antenna systems.Īntenna isolation transformer with a 50 ohm impedance input for use with coax fed antennas It has a Si570 low noise synthesised VFO, relay switched band pass filtering, NXP high linearity RF bipolar amplifiers and built-in USB soundcards. Over 2500 of the RJ 1.1 radio telescope kits have been purchased by schools and amateur scientists world-wide.Īlthough the RJ 1.1 receivers have been discontinued, the Radio JOVE Project continues to support the hardware and software for these original Radio JOVE receivers.The SDR-4++ is an HF general coverage dual diversity SDR receiver covering from 0.85 to 70.5 MHz. When completed, this system could receive Jupiter's natural radio emissions, radio emissions from solar storms, and the natural radio background of the Milky Way galaxy. In 1999, the Radio JOVE project designed a simple decametric radio telescope receiver and antenna kit. The Original Radio JOVE RJ1.1 Receiver Kit This frequency range is optimum for detecting Jupiter decametric radio signals, and is excellent for detecting solar radio emissions, the galactic background from the Milky Way, and natural and artificial Earth-based radio emissions. This SDR receiver, the accompanying Radio-Sky Spectrograph (RSS) software, and the radio antenna, are designed to operate over an 8 MHz wide range of frequencies centered on 20 MHz. In addition, the antenna can also be purchased fully assembled. The Radio JOVE 2.0 Radio Telescope Kit contains the following items: SDRplay model RSP1A radio, a dual-dipole radio antenna, cables and connectors, and Radio-Sky Spectrograph (RSS) computer software to display and record the data.įor your convenience we also offer the receiver and antenna as separate kits, should you not need both.
