I have received some information from the Houston, Texas area that seems to indicate a new UHF trunked system has shown up and is apparently located at the Federal Detention Center in downtown Houston. The current system information is:
Motorola Type II
System ID: 7707
Base: 408.0000
Step: 12.5
Offset: 380
408.1000, 409.6500, 410.0250, 412.4250, 414.3000
The new system is showing this information:
Motorola Type II
System ID: e726
407.4125, 408.4500, 409.4125, 410.2125
Listeners are reporting that 407.0125 MHz may also be part of this new system, but that has not been confirmed yet.
I am guessing this is being done to bring the old system in line with the new NTIA federal UHF channel plan, with 9 MHz repeater offsets. And it may have been easier to simply replace the system than upgrading all the system components already in place. We'll watch for further system info as it becomes available.
UPDATE: As of 12/18.09, this new system is in use and the old system (7707) has been deactivated.
