[Scan-DC] Montgomery County TRS

[MTC Communications]

For the last week, I have heard Montgomery County technicians (probably Teltronics and/or Wireless) talking on the radio 
service talkgroup about changes they were making to the system.  At times they had a tech at each of the 11? sites calling out
the fact that they had loaded software?? on each channel.  Is this the start of rebanding or some type of upgrade?
Does anyone know?
