     They're transmitting on the standard archive/alert
mcast group:

snoop host 146.88.2.246
Using device /dev/le (promiscuous mode)
evla-mib-3-3.aoc.nrao.edu -> 239.192.0.1  UDP D=20010 S=2078 LEN=1239
evla-mib-3-3.aoc.nrao.edu -> 239.192.0.1  UDP D=20010 S=2078 LEN=617

     If you get mcasts from any mibs on that mcast group
you should get them from that one as well, ie it's
not their mcast group its the alert mcast group.
