In this County, the fire depts that are dispatched on the County Fire Channel
will usually switch to the talk-around freq or their own freq, if they have one.
When things get real busy, or involve several depts, then some will switch to the
Tx Fire mutual-aid freqs.
Waco does have the ability to cross-link their 800 system to the County Fire freq
when they are requested for mutual-aid.
The Inter-Op list I got from the State does NOT include AIR 1...only AIR 2, along
with TxLaw 1,2,3,...TxFire 1,2,3, & TxMed 1 , along with the 5 V-CALL channels.
It notes that "Texas AIR 1 is reserved and not available for use in this plan'.
I have all these freqs in our radios now.
