There's a few RRs that use it on unkey to let the dispatcher know who is talking in case he doesn't hear the unit voice ID.
FRED/EOTD are all in the 452.xxxx range, so if he's listening to the 160.xxx dispatcher, he's not hearing the FRED. The FRED channels don't have any voice on them, because any voice would cause interference with the data flowing between the FRED and headend box and could cause some serious issues (emergency air dump). -- John "Smokey Behr" Gleichweit FF1/EMT, CCNA, MCSE IPN-CAL023 N6FOG UP Fresno Sub MP183.5 ECV1852 List Owner x6, Moderator x4 CA-OES 51-507 http://smokeybehr.blogspot.com http://www.myspace.com/smokeybehr
