- LTR Passport
An "LTR Passport" system is a type of LTR
Trunked radio systemthat differs from other LTR types.
Trunked radio siteseems to have at least 3 frequencies:
* A "local" home channel for units that have this site as the home site.
* A "roaming" home channel for units that have another site as the home site.
* A "registering" channel that is used by roaming units to register with the site.
The local home channel is programmed into the radio. The roaming home channel is assigned when the unit registers with a site and seems to be the same for all units that register at that site. The registering channel is the frequency broadcast by neighboring sites in their "neighbor" information.
There are currently no
Radio scanners available that will track LTR Passport systems.
