Sounds like a lot of work on top of the other projects. You guys have a timeline to completion?
All of the VHF sites now have the 7 or 800 co-located GTR racks active except Crestview. It will come later. We've just begun a multi year project that will add almost 200 new sites across the state to migrate to a single band system plus add much more portable coverage across the state.

Care to help identify 002-071 and 02-072? I'm seeing them as peer sites in E TN, but can't seem to get their CCs to hit on my scanning setup?

What was the initial reason for using VHF instead of 700/800 out of interest?

VHF had better coverage in some areas as well as other issues. But now they are going to make it simple by only needing one band setup in all radios for the TACN. Since most agencies are going to NEXT "N" series Motorola radios, they can do the codeplugs more efficiently.

There's a couple of reasons.
You have to remember, TACN didn't just flat out replace the patchwork quilt of legacy systems. It sort of supplanted it over time. (Still going, in fact). 800 is not the best choice for all terrains, and some places were not happy with the performance in testing. I suspect because you can do things in other bands with fewer towers may have also been a driver.
