[Discuss-gnuradio] Si4721 an option maybe?

Hi so I've been looking at the Silicon Labs Si4721 transceiver chip and am currently wondering if it could be pressed into limited SDR service with it's I2S interface. the data sheet indicates a number of interesting features and options. here is the data sheet link, https://www.silabs .com/docum

This may seem counter productive, but have you guys considered writing a good FM signal generator for testing your receivers? at the very least you'll have a way to broadcast within the lab to your stereo system. cheers, Justin N2TOH ___ Discuss-gnura

[Discuss-gnuradio] USRP custom hardware suppliers?

I spotted this discussion midway. Here are a few thought on the matter from an Amateur Radio operator perspective. Depending on the frequencies in question you can use several COTS amplifiers for specific bands needed, and use a Diplexer/Triplex/Quad... (basically filters to separate the bands.)

Matt I know for a commercial product this would be considered a hack, but why not use the new 36 bit SRAM and ignore the extra bits? or conversely use the new chip and create a riser card for it? just a thought... Justin Message: 12 Date: Fri, 14 Jan 2011 12:55:33 -0800 From: Matt Ettus Subj

Could someone be kind enough to make a DVD for me with the raw samples of the FM Broadcast band? The reason I'm asking for this is I currently do not have access to any of the USRP devices, and would like to test an idea I have. Thank you in Advance, Justin N2TOH

[Discuss-gnuradio] adjustable clock oscillator?

Just a thought would something like the Silicon Labs Si 570 anyrate clock be of use for adjusting any of the system speeds? Like nudging the sampling rate up or down to better match what your working with? Justin N2TOH ___ Discuss-gnuradio mailing list

[Discuss-gnuradio] USRP limitations

I've seen conflicting specifications for the receive bandwidth on the USRP, what is the absolute widest chunk of spectrum you can receive with the BasicRX? Also can the total bandwidth be split over a couple of ranges? or is it always a single chunk? Example, can I configure it to cover 1.8-2.0 M
