It depends if they have the actual RF to IS Igating enabled, but I'd
guess that most of them are. However, because of the APRS-IS duplicate
filter, you probably won't seem them at aprs.fi or any of the other
-IS-fed sites.

PS. All I can state with certainty is that they have at least one RF
port configured whose reception traffic is currently fed to a central
server with no filtering. NOT via APRS-IS.
