[Discuss-gnuradio] The RF front-end just got much smaller.

http://socrates.berkeley.edu/~argon/nanoradio/radio.html Watch the movies and imagine an array of nanotube front-ends feeding a SDR. Talk about tiny. Quoting: We constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single

[Discuss-gnuradio] Important bug fixes in trunk and release 3.1 branch - need testing

2007-11-02 Thread Johnathan Corgan
We have three important bug fixes recently checked in to the development trunk and backported to the release 3.1 stable branch. These involve fairly low-level code, and we're interested in users confirming the original bugs are fixed and that there has been no collateral damage. Users tracking

[Discuss-gnuradio] reconstructing original data from GMSK loopback?

Hey all, Is the proper way to reconstruct the original data back from modulating and demodulating with GMSK (in loopback fashion) by packing the outputted bits using gr.unpacked_to_packed_bb()? Since there is 1 bit per byte (LSB), I'm assuming it needs packing. Whenever I add the following
