I've wondered how that system truly covers and is maintained as it is in a weird spot with Bearcom and their relationship with Motorola.
For those who are unaware, Bearcom acquired CTS and all of it's airtime resources (this included the old Wear radio Type 1 stuff in the Waco area) in 2016 and immediately sold off all of the airtime to an investment group. In the Austin (CTS/Texas Comm) and San Antonio (All Points of San Antonio) markets, CTS was selling onto All Point of Round Rock's Connect Plus system. Well, the investment group decided to build their own Connect Plus system for the Austin/Belton market (leaving the Type 1 system in Waco hobbling through life with some independent Capacity Plus here and there in the Waco market). Some drama happened, the investment group's assets were frozen and the licensee who they were leasing spectrum from took over the equipment (happened to be the other founder of All Points who sold the San Antonio location to CTS and later acquired Advantage in Kerrville).
Then comes 2019 and S&P is acquired by Bearcom along with that NXDN system because Bearcom and MCA are having their own version of the Quickening across the US (there can be only one). Bearcom decides to keep the NXDN system and continues to maintain it. The Scott & White NXDN system is a whole extra can of worms...but the bid for that was awarded to S&P prior to the acquisition and at one point it was pushed back to EF Johnson for much of the North Texas deployment.
