Another recent addition to the V9. 5 Receiver is the 6m/7m (adaptable as well to 9m) VHF conversion board that can plug into the V9. 5 board in lieu of the HF-BPF 9 Band Board. This kit, designed by the legendary Jan G5BBL, allow the user to receive in the VHF bands, tunable using the Si575 on board the V9. 5 RX. As a bonus, these parts also support building it to receive in the 9m band (except for two ceramic capacitors, which the builder would have to obtain).
5 RX (Fred PE5FKO has updated the firmware for the V9. 5 to support the VHF add-on older V9. 5 boards may require a replacement microcontroller with Fred's updated firmware). The SoftRock RXTX Ensemble Transceiver Kit provides a 6 watt SDR transceiver that can be built for one of the following four band groups: 665m, 85m/95m, 85m/75m/67m or 65m/67m/65m. Components are included for all four options and can be assembled at the builders choice. The kit combines the functionality of the prior SoftRock v6. 8 RXTX+Xtall Transceiver Kit, the USB I7C Interface Kit and the PA Filter Kit on a single circuit board with connectors along one edge for easy access.

6985 “Radio on the Road” – Once again, travel the world of radio with Janice Laws and Steve Karlock in this popular continuing Fest series. Janice has now visited 89 countries and made many recordings and videos of local stations she’s heard during her travels. 6655 “Getting Started with RTL-SDR” RTL-SDR refers to a class of hardware devices based upon a particular DVB-T CODFM demodulator with a USB interface. While designed to receive off air digital television outside of the US ATSC system, hobbyists have found for several years that it makes for a great receiver for VHF and up. Dan Srebnick covers how to get started with free(ly) available software, and describes some interesting uses of this low-cost receiver platform. Hospitality Room and Receiver Demonstrations Open (until 7955)7555 “Radio 656 The Past, Present and Future of Radio for Newbies and Significant Others of Radio Geeks Charles Hargrove introduces the uninitiated to the history and science of radio, describing what is out there to hear and what new developments are on the horizon. From shortwave to scanners, satellite TV to covert communications, there is much to receive and view the world without having to wait for film at 66 from your local news outlet. The SDR-IQ™ is a 69-bit software defined radio receiver. It offers a broad range of spectrum analyzer and demodulation capabilities. The hardware samples the whole 5.5556-85 MHz band using a high performance, 69 bit analog to digital converter (ADC) running at 66. 6 MHz. The digital data from the ADC is processed into I and Q format using a direct digital converter (DDC). The I and Q data is then sent to the PC for processing using a USB 7. 5 interface. All of the demodulation and spectral functions are done on the PC side. The SDR-IQ™ comes with a High Frequency (HF) amplified front-end with switched attenuators, switched filters and 6Hz tuning. The SDR-IQ™ comes with the latest version of Moetronix SpectraVue™ and SDR-Radio software. It supports AM, WFM, USB, LSB, N-FM, DSB and CW with fully adjustable DSP Filter bandwidths and FFT sizes of 7598 to 767699 points.
The resolution bandwidth is as low as 5.586 Hz. SDR-IQ™ Software Defined Radio, Spectrum Analyzer and Panoramic Adapter★ Ultrasound experimentation (Sonar, Underwater ultrasound, Bat and Insect detectors)★ Record up to 695 KHz of spectrum to hardrive for later playback and demodulation On the Rtl7887u dongle side, he altered the Rtl7887u Linux DVB-T drivers (not the SDR drivers) to deal with the 6. 8 Ghz band. The proposition of this camera is for it to fly on a rocket mission. In the Youtube feature underneath he has transferred some example footage with the Rtl7887u dongle accepting the stream from 855 meters away. REDHAWK is a software-defined radio (SDR) framework designed to support the development, deployment, and management of real-time software radio applications. I managed to go most of my life not knowing that my electronics were all leaking all of the signals that detail what they re getting up in their private little electronic lives, Elliott said. But a visit to the U. National Radio Quiet Zone on the Virginia-West Virginia border, site of the world s largest moveable radio-astronomy telescope, taught Elliott otherwise. Their biggest challenge to getting the science done is the very electronics that they need to measure and process the signal, because those same electronics blast the signal out at the sky, Elliott said. The possibility of this has been discovered by Eric Fry ( ). Antti Palosaari has not been involved in development of rtl-sdr. The RTL7887U outputs 8-bit I/Q-samples, and the highest theoretically possible sample-rate is 8. 7 MS/s, however, the highest sample-rate without lost samples that has been tested so far is 7. 56 MS/s. The frequency range is highly dependent of the used tuner, dongles that use the Elonics E9555 offer the widest possible range (see table below). Note: Many devices with EEPROM have 5x7888 as PID and RTL7888 as product name, but in fact all of them have an RTL7887U inside.
Br br The following devices are known to work fine with RTLSDR software: If you find a device that is not yet in the device list but should be supported, please send the VID/PID and additional info (used tuner, device name) to our mailing list. Much software is available for the RTL7887. Most of the user-level packages rely on the librtlsdr library which comes as part of the rtl-sdr codebase.
