The Defense Department’s ambitious program to equip the military services with a family of digital
combat radios has run into significant roadblocks.

These's some cool new stuff in CVS.
You can now build hierarchical blocks out of primitives, hierarchical
blocks and random python code. They are composable, and can be
connected up just like regular blocks. This gives us a good way to
start aggregating common functionality.

Hi folks,
I'm trying to play with the fsk_rx.py and fsk_tx.py in
gnuradio-examples-0.3/python/usrp1. Tx seems to be working, as the post
modulation graph is showing signs of life. However, the Rx post
modulation shows no activity. I have Tx and Rx dcards connected via a

Is it just me or do others experience problems in receiving email from this

Yep. After a 'modprobe ehci-hcd' everything is working perfectly! Thanks!
Also, the nVidia CK8S USB controller seems to be able to handle 32MB/s

While that sounds interesting (particularly as I'm a part-time radio
astronomer), what
you'll find is that most of the more sensitive facilities would rather
not have
transmitters of any kind anywhere near them--even their own.
At some facilities, the vehicular traffic within the facility is *
