[Discuss-gnuradio] CPU loads and reqs?

2006-10-22 Thread Dave hartzell
Hi, I'm curious what CPU and speeds are recommended for some of the USRP and WxPython apps... When I run the usrp_wfm_rcv.py application, I get choppy audio, freezes in the Wx display, and overrun/underruns (OuOuOuOu) characters on the CLI. When running Top, I see that "python" and its children

Dave - Could you give details about which Mac you're running on, OS version, how you installed GR and prerequisites, and the like? That might help (might not too, but at least it's another statistic). - MLD On Oct 22, 2006, at 5:29 PM, Dave hartzell wrote: The non-WxPython apps seem to run
