FUNcube SDR Receiver as USB stick (Software Defined Radio)

Nuova versione

The SDR USB dongle FuNCube Pro Plus is an SDR (Software defined radio) receiver built as a USB stick. The receiver covers a frequency range of 150 kHz to 1900 MHz and can display/receive a spectrum of up to 192 kHz.

The FUNcube SDR receiver was developed to support the FUNcube satellite project of AMSAT-UK. This project is intended fo schools and pupils, who have the requirement for a very cost effective receiver. So Howard, G6LVB set out and developed the FUNcube SDR USB dongle!

FUNcube SDR receiver can be used to receive practically any signals on VHF and UHF: NFM, AM, SSB, CW, Data - whatever the software supports. And suitable software is available in many forms, most of them freely available on the internet: Linrad, Moetronix SpectraVue, Rocky, M0KGK and many others. The FUNcube SDR stick behaves like a soundcard towards the computer. The required drivers are already available with most operating systems like Windows 2000 SP4, Windows XP, Windows Vista and Windows 7 (32 and 64 bit), but Linux and Mac OS X is also possible.

The Funcube-SDR Pro plus has eleven discrete front-end preselection filters, including some SAW filters specifically for 2m and 70cm amateur bands, and so has considerably better intermodulation stability and fewer spurious responses than usual DVBT sticks.

To start using the FUNcube SDR dongle, the firmware (the software on the dongle itself) must be updated. This requires the download of the appropiate Windows software from the developers website and installation of the latest firmware. So, a little bit of computer work is required before the FUNcube SDR can be operated. Further a coarse frequency alignment is recommended. How this is done is described in detail in this english document (funcube_setup.pdf) (PDF, EN, 2.8MB).

The FUNcube SDR USB dongle has a female SMA connector for the antenna and works on any computer with a USB 2.0 interface, operating system see above. The sensitivity on 2m and 70cm is approx. 0.15µV. It is recommended to use an USB extension cable to get away from noise from the computer.
