2010-12-01 Thread David Campbell
Hi, I've noticed that with the aforementioned configuration that when I set the gain between 0-40 dB that the actual gain out is 0-70 dB. I've seen this across multiple units. Is there a fix for this? Thanks, David ___ Discuss-gnuradio mailing l

[Discuss-gnuradio] CPU Utilization and USRP2

2010-11-04 Thread David Campbell
Hi All, I've noticed that the C++ interfaces provided in gnu-radio and UHD for usrp2 data streaming are CPU-intensive (UHD moreso than gnu-radio). I am wondering if there are easy ways to mitigate this or are there plans in the future to diminish these. For UHD a decimate by 16 process che

[Discuss-gnuradio] DBSRX with USRP2

2010-07-06 Thread David Campbell
Hi All, I've looked at the gnuradio wiki on how to configure the DBSRX for use with the USRP2 (http://gnuradio.org/redmine/wiki/gnuradio/USRP2DBSRXModification ), and they mention a firmware file to upload that I cannot find (burn_dbsrx_eeprom.bin). Is there a new way to configure the DBSR
