Colibri-NANO SDR receiver

The Colibri-NANO USB stick is a powerful direct sampling SDR reveiver. The frequency range covers 9 kHz to 55 MHz. The AD converter uses 14 Bit width, which results in an excellent 110 dB BDR. The samle rate is 122 MHz, together with the anti-aliasing filter this offers a direct samplig receiver up to 55 MHz. The filter can be turned off so you can use the receiver in undersampling mode (with reduced parameters) up to 500 MHz.

Due to the improved, faster processing of teh IQ data on the SDR a larger sample width of 3 MHz is achieved. I.e. the realtime spectrum display can be up to 3 MHz wide. This is an excellent value for this class of device! The supplied software ExpertSDR2 offers a receiver for all usual modes. Digi modes can be decoded by external programs using the support for virtual audio devices VAC.

Another nice feature of the Colibri-NANO SDR is the combined attenuator/pre-amp stage which can be finely adjusted in 0.5 dB steps from -31 to +6 dB. Together with the low noise floor (-127 to -131 dBm) and an excellent sensitivity of 0.05 µV the result is a receiver with excellent large signal handling capabilities. The Colibri-NANO is a perfect HF scanner, whether you are in a noisy or in a very quiet enviroment.

The Colibri-NANO is either operated directly attached to the computer of the user, or can be used remotely at a distant location. This is daone with the freely available ExpertRemote software. At the location of the SDR a small computer is required, for example a Raspberry-Pi; for the internet connection a relatively slow link like LTE or 3G is sufficient. This allows you to use the SDR receiver at a convient and quiet location anywhere on the world.

Colibri DDC SDR with Ethernet interface

http://www.n9vv.com/Images/SunSDR2/Friedrichahafen-2014/colibri.pngColibri DDC SDR is a direct sampling HF receiver (direct down conversion, DDC) with a frequency range from 0 to 55 MHz. The AD converter has 14 bit word length, the sample rate is 125MS/s. This makes the Colibri SDR suitable for demanding shortwave listeners (SWL), radio amateurs and professional monitoring applications.

The receiver of the Colibri SDR offer a frequency range from 9 kHz to 55 MHz, which is sampled directly by the ADC. With the use of oversampling and additional (optional) anti-aliasing filters, the reception range can be extended up to 800 MHz, although with reduced parameters. The Colibri provides a 55MHz low pass filter at the input, followed by a switchable 20 dB attenuator. The high clock rate of 125 MHz is supplied by a temperature controlled oscillator. Optionally an external 10 MHz clock signal can be supplied when highest precision is required. The 14 bit AD converter is followed by a powerful FPGA chip, which handles the SDR typical data reduction, and sending the data over the Ethernet interface. Additionally an analog audio output is provided for convenient listening to received signals. The benefit of this output is that the signal is only minimally delayed. The analog output uses a 24 Bit DAC and is suitable for headphones.

A speciality of the Colibri DDC SDR is the Ethernet interface, which allows the receiver to be integrated into a local area network or to be connected directly to one computer. In contrast to other radiso whioch use USB connections, an Ethernet connection allows for much higher data rates and longer cable distances. Even remote operation over a LAN is possible. To provide a hassle-free and seamless integration into the network, the Colibri SDR offers automatic IP adressing by provinding a DHCP server, if required. With this function you can connect the SDR directly to one computer, without a network switch. Just connect the receiver to ypur computer and go! This is perfect for vacation use or portable operations. Of course the Colibri SDR also supports static IP addressing for fixed environments.

The supplied "ExpertSDR2" software offers the display of the entire spectrum up to 62.5MHz as a panorama view. Within the specturm tweo independant receivers can be places, both offering up to 312kHz bandwidth. Both receive ranges are shown with spectrum and waterfall display. The software offers decoders for all usual modulations like LSB, USB, DSb, AM, S-AM, FM. WFM and CW. The IQ data can be supplied to external program decoders, as well as the demodulated audio data for decoder programs like FLdigi or similiar (requires "virtual audio cable" (not supplied)).

A built in interface offers 7 freely programmably digital output ports (open collector). With these signals the sftware can for example select different antennas or filters, depending on frequency. This interface also provides a "mute" input, which allows the Colibri SDR to be integrated into a HF transmiter station. The ExpertSDR2 software requires Windows XP,WIn7 or Win8 (32 and 64 bit variants), a version for Ubuntu x64 is also available and a version for Mac OS is announced for later availability.

The Colbri DDC SDR receiver has a 50 Ω SMA antenna input, the same connector as the (optional) external 10MHz clock source. An adaptor cable SMA to PL female is supplied. The required supply voltage is 5V DC, a wall plug power supply is included. The current consumption is approx. 700mA. The receiver case has a size of 64x24x112mm, the weight is 300g.
