Thanks Jim
But does anyone know the actual freq. It's not contained in the link. It just says "near 915MHz"

Some neat reading on this website about the same type of device...

COMMUNICATIONS
Frequency Range
Downlink: 911.75 to 919.75 MHz adjustable in 0.25 MHz steps
Uplink: 902.25 to 903.75 MHz and 910.00 to 921.50 MHz adjustable in 0.25 MHz steps
Actual frequency range is protocol-dependent.
The above frequencies are in the location and monitoring
service (LMS) band.

Took a little looking, but CCR T21, section 1704.2:
"The RF carrier frequency shall be taken from the 915 MHz + 13 MHz range. Specific frequency and bandwidth depend upon pending FCC assignment."
Strangely, the only mention of automatic vehicle identification systems at the FCC site was Part 12.251, but that's up in the 1+ Ghz area (don't remember exactly what freq).

That's what I'm talking about
I figured they would be unlicensed, sO didn't think to look there.
914.25
917.25
903.00
914.00
917.00
912.75
918.75
Are bridges
914.0
917.0
Are Sunol Grade toll lanes.

You're welcome!
I might have missed a license or two when I was searching by frequency, there were a whole lot of expired ones to sort through (looked like mostly old AVL stuff). There is also a bunch of licenses in San Diego, for the HOT lanes down there.
