[Mich VHF UHF Society] 50 MHz to 6 GHz SDR Transceiver Presentation

[richard.schober at comcast.net]

I've been digging through Pacific Northwest VHF-UHF-Microwave Conference proceedings lately and was really intrigued by this one.  I haven't followed SDR very closely but this would allow of a nicely integrated mobile station.  The missing component it a decent broadband amplifier.  Some of the GaN HEMT offerings at Quorvo.com could do the trick there.  The Ettus B210 SDR transceiver board mentioned is about $1200 at the moment.

My current station is entirely homebrew and consists of two second generation SDRs, one for HF and one for 50 MHz and above.  The HF SDR is based on a multi-mode DSPs that I have authored using GNU Radio with GNU Radio Companion:  http://gnuradio.org/redmine/projects/gnuradio/wiki.  This DSP software is linked to an Ettus USRP N210 SDR transceiver module that I am using to operate on HF; www.ettus.com/  The 50 MHz and above station uses the same DSP software and is linked to the Ettus B210 SDR transceiver.  The B210 SDR transceiver is a state of the art, direct conversion SDR, based on components from the broadband digital data communications industry.  This modern SDR architecture lends itself to high performance narrow band amateur applications and permits operation from 50 to 6000 MHz.  The rig is easily packaged for both home station and rover operation.

The DSP programming tool that I am presently using is the opensource GNU Radio DSP software library.  This opensource software library permits flexible programing in C++, python, or with a graphical user interface (GNU Radio Companion), depending on ones programming abilities.  More information on GNU Radio is available from the GNU Radio Wiki:  http://gnuradio.org/redmine/projects/gnuradio/wiki  and on my GNU Radio Companion website: "Ham Friendly DSP": www.w7fu.com
