[Scan-DC] Anne Arundel Co control channel(s)

[Chas Armstrong]

Hello:

I'm about to receive a new bc250d shortly.  I live in Annapolis, so I'm
interested in tracking the AACo Police, AACo Fire, and Annapolis City
Police.  I've never had a trunktracking scanner before, and I'm a bit
confused about the control channel(s).  A source list several control
channels for AACo.  I thought that there is only 1 control channel per
system.  Is their a separate control channel for eac service, i.e. 1 for
AACoPD, 1 for AACoFire, and one for AACityPD?

Thanks,

Charley
