The database shows a GATRRS site 1-010 Central Austin with the following frequencies:
764.46875c
764.93125a
765.21875a
765.68125a

Those frequencies are not in the current narrowband public safety part of the 700 MHz band. Somebody in Austin should verify that they are real. Somebody could have unknowingly submitted image frequencies or they could be old frequencies from before the 700 MHz band was reconfigured about 10 years ago.

There is an attachment to a FCC Notification Requirement for the 700 MHz State License WPTZ776 filed a few weeks ago that lists several frequencies that the state is allowing other systems such as GATRRS, LCRA and TxWARN to use.
One set of them is labled "DPS Austin-Capitol" with lat/lon coordinates at a state office building next to the capitol. It has the following frequencies:
773.28125
773.56875
774.03125
774.31875
774.78125

Somebody in Austin should scan those to see if any are control channels. I suspect that the database is wrong and these are the real frequencies for that site. If not, they could be part of some other system or conventional repeaters.

Hi Tom,

I drove through Austin earlier today and can confirm that 764.46875 is a control channel on the system. The Home Patrol showed that it was site 10 like the database says. I didn't hear any voice. Also I didn't hear anything on the other frequencies you posted.

Thanks. I just thought it was strange that there would be a narrowband trunked system on frequencies that are part of the broadband allocation that was auctioned off for the future nationwide LTE network.

I'm getting good copy on the 700 system this morning. I heard traffic from the Capitol units using the RR listed frequencies.
