Hopefully they at least include the GCI talkgroups for future interconnection with GATRRS and TXWARN.GMRS has structured their I/O's to mimic FWRRS. The two systems are also sharing all the I/O's with one another to assist with cross Metroplex coverage.
Rockwall intends to structure their I/O's the same and share with GMRS. FWRRS has led the charge on a structured I/O plan that works well across all agencies.
For those of you not from the region, every 700/800 radio in SE Texas has WARN zones 75-80 programmed, including 700/800 users not on TXWARN. Good to see the DFW region taking the same approach with disparate systems.
