New MOTOTRBO in DC

While in downtown DC on Saturday, I heard MOTOTRBO transmissions on two new frequencies: 463.7250 and 464.5750. A check of the FCC database for the former did not turn up any TRBO licenses. The latter may be the Marriott Wardman Park, which has had the frequency licensed for TRBO for some time, but has continued to operate in analog mode.
