tobgs...you're incorrect. No offense.
Section 4 (Which is UHP road Troopers in SL) doesn't use Channel 6, unless the road Troopers are talking to the SLCC guys, which they will do. The SLCC guys will come back the road guys, and vice versa. One of the reasons you're likely hearing less formal conversation on those channels is because the actual dispatch functions, for even the SLCC guys, are done using UHP's frequency, not the SLCC one. They don't have a dispatcher who monitors the SLCC channel, it would be a waste of man power.
Such a change will only cause confusion down the road when SLCC changes the contract and UHP is no longer using said channel
