[Discuss-gnuradio] Windows Build environment -- Cygwin or MinGW?

2010-11-30 Thread Kevin Dixon
I'd like to get started building GNURadio for Windows, using the USRP 1, with the goal of writing some custom blocks. Do people prefer Cygwin or MinGW style installations? Off the cuff, Cygwin looks more straightforward. Any opinions? Thanks in advance Kevin _

[Discuss-gnuradio] software-defined GNSS receiver people in Asia

2010-11-30 Thread Fabrizio Tappero
Dear All, I apologize for bugging people on this mailing list for this but I do not know an alternative way. I am looking for people located in Asia doing GNSS stuff with GNU Radio or other SDR softwares and interested in sharing some Asian GNSSs (e.g. QZSS) data or implementation. In return I can

[Discuss-gnuradio] About the directionality of the LP0410 antenna.

2010-11-30 Thread Miok Wah
Hi all, We hope to do some experiments with the LP0410 antenna. Before that, we hope to know more about its characteristics: 1. Is it a directional antenna? 2. If so, is there statistics about its directionality (e.g., beamwidth)? We did not find relevant information in its data sheet. Hope
