Dear Roy;

Alas, many of the SDR announcements (see http://imj.ucsb.edu/sdr-monitor/ )
are "dead," or are announcements of future availability. You should be able 
to see
our groups (on-the-I), and also the UOregon groups, besides the ones
you mentioned. If you can't see On-the-I, let me know and we'll debug it.

The Norway NRK MP3 stations are frequently up too - send e-mail to the contact
address if they are not, and he'll reboot them.

Accroding to accessgrid - http://beaconserver.accessgrid.org:9999/ - the 
UMich beacon
can see us, but NO ONE can see it, so you have some sort of outbound 
connectivity problem.
