On Beulah Road, Chesterfield County, VA, USA : Road work crews have flaggers/sign holders that are using FRS channels that announce when they are releasing their traffic and announcing the last vehicle so / before the other can release their traffic. Another location is on Genito Road at Otterdale Road. Same thing happens here. Unknown PL / "code" for both locations due to the fact that I am driving and won't look down at the display I will watch for it at a stoplight My Bearcat BCD 396T will display the PL tone when someone keys up on that frequency/channel using PL tone.
