Re: [Discuss-gnuradio] Low cost SDR hardware
Hi Manu, What is your output power requirement? Frequency coverage? Do you have a target price? Do you have LO phase coherency requirements? Support for nuand's bladeRF was just recently pushed to gr-osmosdr for both GNU Radio 3.6 and 3.7. The output power is 6dBm CW, so with some backoff for linearity and PAPR on your transmission signal, you're probably at -6dBm or so for transmission. Harmonic filtering is required if you plan to hook it up to an antenna. The frequency coverage is from 300MHz - 3.8GHz and costs $420/board. More information can be found here: http://nuand.com Feel free to e-mail me directly off list if you'd like to discuss more. Brian Full disclosure: I'm involved with nuand and bladeRF.

Re: [Discuss-gnuradio] Low cost SDR hardware
Hello, For just teaching even a speaker and microphone work well to add real world effects like AWGN, echos, delays, and Doppler effects on communication channels. Does everyone need a transmitter? Over here we have just one USRP and a whole lot of RTLSDR's so everyone can practice receiving and demodulating real signals from outside sources and when needed signals generated in lab.

There is of course the (quite awesome) HackRF[1] which will eventually be sold for roughly $300 (not sure what the price break for 100 units might be). That being said, it's still in beta and there aren't anywhere near 100 units available at the moment. You might be able to get in touch with mossmann (CC'd) to see if you could use his production contacts to do a small production run.

Re: [Discuss-gnuradio] Low cost SDR hardware
I get the feeling that you would like something significantly lower cost to support 100 units. Arrow Electronics partnered with several manufacturers to develop the BeRadio (http://www.arrownac.com/solutions/beradio/). There is no driver/FPGA build for an interface to Gnuradio, but with enough students working on it, it should not be a problem. Single part price is $79 but I expect Arrow may give a significant price break for a university.
