I know several of the Dallas/Fort Worth (DFW) sites have control channels on the air again, but is the system really supporting paying subscribers?
Anterix is keeping most of the frequencies once the rebanding of the 930MHz band completes, and it is likely they may be keeping the control channels active, so they don't get tagged by the FCC for inactivity until such a point they replace the repeaters with the wideband gear that is to replace the TeamConnect Connect Plus system - which of course can't happen until all other licensees are out of their new wideband block. If the controller is online for those sites, some subscriber radios may still affiliate and be using the system rogue, meaning activity is going to be hit or miss, and could stop working again at any time.
They also got 10-year renewals on a bunch of their licenses last year, again likely placeholders until the rebanding is complete. Many of them do not have DMR emissions designators and the ones I'm looking at are using 13K6F3E (900MHz Analog Voice) and 13K6W7W (900Mhz iDEN)
I can tell you from my listening post, where I could hear 4-5 sites before the shutdown, a quick sweep of the band only showed one, and that signal is weaker that it used to be (it happens to also be the closest, about 5 miles line of sight) - it also happened to be outside the frequency band that Anterix is keeping (Control Channel 936.3125).
I have a screenshot from RRDB showing the DFW sites before they were removed in early 2021, along with my submission archive (I cleaned a bunch of the sites up in 2020), so I could theoretically resubmit everything back into RRDB, but at this time, I doubt there's any paying traffic left on it. I also heard and had seen additional sites while travelling around the DFW area, that would have pinpointed their location more accurately, but knowing the system is theoretically dead, didn't take time to really log them.
