This is 1960's technology.
Yes, we're talking about the Andy Griffith era.
Barney Fife relied on these antennas and so did the Tennessee Highway Patrol ..
Well, that was until recently when they moved to a new digital multi band radio system.
Colonel Tracy Trott, with the THP, says, "This is especially important when it comes to emergencies such as the one we witnessed in Oklahoma last night. Communication will be key in any of those types of situations."
Troopers tell us the old radio system was unreliable and depended a lot on the weather.
It also put troopers in danger.
On occasion, they had to drive and physically look down to change channels, all in order to talk to a dispatcher.
Troopers admit they've had to use their cell phones in the past to communicate effectively.
Commissioner Bill Gibbons, with the Tennessee Department of Safety and Homeland Security, says, "Our troopers were dealing with a radio system that was 30 plus years old, and we were putting band-aids on that system to keep it working."
Peeling off that band-aid cost the state $120 million dollars.
But now, troopers across the state can talk one another without pressing extra buttons, and the radio sounds crystal clear.
Jay Malpass, a strategic projects managers with Motorola, adds, "It will keep the troopers safe while they're keeping us safe."
Knoxville will be switching over to the new system on May 29th.
We're told California is the only state now that is not using the new system.
