Unlike other DDC type Software Defined Radios that use a dedicated DDC chip or an inadequately sized FPGA, QS1R allows future expansion, room for experimentation, and upgrades because of its generous Cyclone III FPGA with many DSP resources.The firmware, software, and FPGA HDL for the QS1R Receiver is available for experimentation and writing yo...

The QS1R VERB is the most advanced open source digital down conversion (DDC) receiver board on the market featuring a 50Mhz panadapter display (selectable down to 50Khz) and …

Jan 22, 2011 · The Quicksilver QS1R Receiver is a software direct sampling receiver. It features a Linear Technologies LTC2208 16 bit, 130 MSPS Analog Digital Converter (ADC) and an Altera EP3C25 Cyclone III FPGA. Connectivity to the PC is through a high speed USB 2.0 interface. Specs: Resources:

Apr 27, 2013 · The QS1R is a top-notch software defined radio for 0 - 62 mhz - covering longwave, AM, shortwave, and up through the 6M ham band. My setup includes a Wellbrook 1530s+ "magnetic" loop (aka low noise) with a rotor on a ten foot pole in my backyard.

The Software Radio Laboratory QS1R is a high performance direct sampling software defined radio (SDR) that covers 10 kHz to 62.5 MHz. SDRMAXV software is provided by the manufacturer via electronic download. Up to date source code access is available to users who sign a NDA.

I2C is a two-wire communications bus/protocol developed by Philips. SMBus is a subset of the I2C bus/protocol and was developed by Intel. Implementations of the I2C bus/protocol may require licenses from various entities, including Philips Electronics N.V. and North American Philips Corporation.

A QS1R SDR can be used in conjunction with CW Skimmer Server to operate an RBN receiver capable of receiving 7 bands simultaneously. While skimming can be performed using only CW Skimmer Server and RBN Aggregator, using the CWSL_Tee and CWSL_File software allows simultaneous decoding and I/Q data recording of each received band.

Frequency Coverage: 10 kHz – 62 MHz ; undersampling possible through 300 MHz

Apr 16, 2016 · The QS1R was a well-respected SDR that had been on the market for several years. It would be great to see an updated version on the market.

SoapySDR driver for the QS1R radio -- a software defined radio in the HF frequency range. The QS1R was a very elegant SDR radio available ~ 2010. It has been out of production for a …
