Just wondering. Adding more to the scan list slows it down.
Very much so. Here in Las Vegas, we have whats called a Radio Rodeo I believe every 3rd Wednesday. A rep from all of the first responder agencies (local, state, and federal) are supposed to participate. They utilize both VHF and 800 MHz NEViFOG and iFOG channel lineups as theyre usually crossband linked. The interop channels really come alive every New Years Eve as thousands of people pack the Las Vegas Strip.
Each bank/group in my 436HP is dedicated to something different.
Group 1: Law Enforcement
Group 2: Fire & Forestry
Group 3: Wildland Response
Group 4: Medical
Group 5: Interoperability
Group 6: Transportation
Group 7: Utilities
Group 8: Miscellaneous
Group 9: Milcom
Group 10: Fedcom
Group 11: Resorts
Group 21: Quick Save
Unfortunately Las Vegas is all trunked radio systems. Where I lived in California, it was mostly conventional so I was able to make Group 1 a Priority Dispatch group. This group contained only local dispatch channels for police, fire, EMS, Fish & Wildlife, State Parks, Forestry, etc.
The priority dispatch group sped up scanning tremendously. LA County Fire dispatches the entire county on one channel and units would talk to dispatch on their home TRO channels. So where I lived I programmed the priority group like this...
LASD DISPATCH 5
LASD L-TAC 8 (L/O)
LACFD BLUE 8 DISPATCH
LACFD BLUE 12 (L/O)
LACFD AIR TO GROUND
AMR DISPATCH
...etc
I was able to scan every agency/department and not miss much.
