Service Search Object (SRVC)
A Service Search Object (SRVC) is similar to a LMIT search but is optimized
for a specific radio service, and can search for activity associated with a
type of service across multiple frequency bands.
Essential Service Search parameters
The only critical parameter needed for a Service Search to function is the
service type. When you set up a Service Search, you will want to specify the
type of service that you wish to search.
To create a new SRVC object, press PROG to place your scanner into
Program Mode, then press the NEW softkey, then press the SRCH softkey
to view the available Search types, then press the SRVC softkey. Scroll to
the Srvc: field and select the type of search you want to define using
the 34 keys on the 5-way pushbutton pad. Service types include Public
Safety, Aircraft, Amateur, CB, Marine, FRS/GMRS/MURS/DOT and Railroad,
