While searching today, my scanner hit on 152.9050, stating that it's a Cap+ system with a color code of 3. There is no network or site information available, and the frequency does not seem to exist according to my search of the FCC database. The transmissions that I've heard so far have all corresponded to school bus operations in the city of Boston. WQSW689 is a trunked license belonging to Chris Klinger which includes 152.9075 with the emissions designated 7K60FXE. I was wondering if anyone had monitored this system before to confirm that this is the correct system. In the interest of full disclosure, First Student is also allocated this frequency in Connecticut, but its license only includes two frequencies.
