Potomac Mills Switching to MOTOTRBO?

Potomac Mills security guards are now carrying MOTOTRBO portables. They are still transmitting on their analog frequency (463.6000 [ d723]) for now, however. This frequency has never been licensed. The license for the housekeeping frequency (461.3000 [ d043]) shows a pending application for a modification. The modification adds the emission designator for MOTOTRBO. Perhaps security will move onto this frequency on one slot, with housekeeping on the other. (MOTOTRBO allows two talkpaths, or slots, on a frequency.)
