I was told by a cop, Law Enforcement Assist. I'm sure the "A" varies from cop to cop.
There is TG on the story co system labeled "LEA", which Rich83 is referring too. However it isn't linked to any ISP LEA repeaters. Its either a county agency thing or its not the right description for the TG. I have listened to it before, sounds more like a "channel 2" too me.
A number of weeks ago the SCSO were having trouble with the main channel they use, I dont know if its a dispatch or channel one but they said that they were going to use channel two but annoyingly I never heard any more but I do think its odd there is only one channel listed.
That TG-57424-is used by Story County to dispatch for local cities, like Nevada and Story City.. I have heard them call this talkgroup 'LEA'. Not sure if it might also be 'Ch 2'.
Is that why Nevada PD dont have a dispatch channel of their own? I know they have an ops 2 that Iv heard them use a few times but its pretty rare mind you nothing ever seems to happen here in Nevada they just do loops round town bored to death
