This device contains a high-stability local oscillator, mixer and filters to convert an incoming frequency range of 1700-3500 MHz down to 0-1800 MHz. This can be used to extend the frequency range of VHF/UHF receivers, both WiNRADiO and third party products.
The local oscillator is stable enough for the down converter to be usable even for narrow-band modulation modes, and has a low noise figure to be useful for professional as well as consumer applications.
WinRadio products are available only to customers in the U.S. and Canada.
The WiNRADiO ERD-1500 Electromagnetic Radiation Detector is an exceptionally efficient "RF Sniffer" developed to quickly and reliably locate sources of electromagnetic interference. The detector contains a miniature wide-band antenna with a quality amplifier and high-performance Schottky barrier detection diodes for maximum sensitivity.
This wall mounting bracket makes it possible to mount the G3E series receivers to a wall or under a desk, thus saving space. An elegant and useful accessory.
With the standard WR-G305e/ WR-G315e receiver, the FMW mode button is disabled and the wide FM demodulation mode is not available. This is because wide FM demodulation cannot be provided within the signal-processing constraints of the WR-G305e/ WR-G315e software-defined narrow-band receiver architecture.
However, wide-band FM demodulation capability is available as a factory-installed option. The wide-band FM demodulator option is in fact a self-contained "hardware-defined" receiver which shares only the main receiver's front-end and first mixer, but has an independent wide-band analog processing circuit with a conventional "hardwired" demodulator.
If the Wide FM Option is installed, the FMW button becomes active. The demodulator spectrum display shows real-time spectrum of the demodulated audio. In the Professional Demodulator there is a user-definable audio filter, displayed superimposed over the audio spectrum and graphically adjustable.
XR modification includes an additional external SMA connector, which can be used to connect an external reference oscillator for the highest possible frequency accuracy. This external oscillator can be any frequency from 8 to 20 MHz (the user specifies this frequency via software). The input is available at an additional SMA connector, it is AC coupled and has an internal impedance of 150 ohm. The reference oscillator signal can be either sine or square wave between 100 mV to 5 V peak-to-peak.
The RO modification includes an additional external SMA connector, which can be used to output the internal reference frequency. This is useful for situations when the receiver's own internal oscillator is to be used as a reference for other equipment, or, if an external reference is used, to provide this external reference to other receivers in a daisy-chain arrangement. If the receiver relies on its internal reference oscillator, this option will provide 16.384 MHz reference output. If an external oscillator is used, then the external oscillator frequency will be provided at this output. The output is at an additional SMA connector, DC coupled, sine-wave at HCMOS levels (i.e. approx 0.6 to 4 V peak-to-peak) with an internal impedance of 150 ohm.
The IF0 modification includes an external SMA connector, which provides a wide-band IF output (prior to the roofing filters) at the first intermediate frequency of 109.65 MHz.
As an alternative to the (/IF0) option, the IF1 receiver provides a wide-band IF output. The difference is that this option involves an additional internal down-converter which converts the 109.65 MHz IF down to 10.7 MHz.
This IF2 modification provides a narrow-band IF output at 16 kHz, its bandwidth limited by the receiver's 20 kHz roofing filter. This is a useful option for low-cost experiments with Software Defined Radio concepts, because the frequency is low enough to be digitized by a standard PC sound card.
The WR-LNA-3500 Low Noise Amplifier is a ultra-low noise figure preamplifier designed to operate in the range of 30-3500 MHz. While it is ideally suited to WiNRADiO VHF/UHF receivers, it can be also used to improve sensitivity of most third party receivers.
The WiNRADiO AMFE™ Antenna Multiplexer and Frequency Extender fulfills a dual role of an antenna switching unit and a frequency down-converter, making it possible to easily interface separate HF, VHF, UHF and SHF antennas to a wide-band receiver, as well as provide frequency down-conversion for input signals up to 8599 MHz.

The 180 modification features extended frequency coverage from the standard 9kHz-30MHz to 9kHz-180MHz. This makes it possible to use this receiver for narrow-band communications in the VHF range. The receiver's variable IF bandwidth makes this receiver particularly suitable for surveillance and monitoring of airband and other civilian and military communications.
The IF4 modification includes an external SMA connector, which provides a wide-band IF output of the entire 9 kHz - 30 MHz input band, up-converted to 45 MHz (i.e. 9 kHz corresponds to 45.009 MHz, 30 MHz corresponds to 75 MHz). This makes it possible for the receiver to be used as a front-end tuner for HF monitoring systems requiring the capability of digitizing the entire HF band instantaneously; or a front-end for a spectrum analyzer, taking advantage of the receiver's excellent sensitivity and low noise-floor level. This output is located at an additional SMA connector, with 50 ohm impedance and 18 dB gain (relative to the receiver's input level).
This option can be used to output the internal reference frequency. This is useful for situations when the receiver's own internal oscillator is to be used as a reference for other equipment, or, if an external reference is used, to provide this external reference to other receivers in a daisy-chain arrangement. The output is DC coupled, sine-wave at +5 dBm @ 50 ohm impedance. It can be directly connected to an external reference oscillator input of another WR-G39DDCi receiver. Note that the output is available when the receiver application is running and the receiver is turned on.
