When I have been monitoring the James City County/Williamsburg/York County system with Pro96, I observed several previously unidentified talkgroups. The unidentified talkgroups are 1105, 1106, and 1107. The radio I.D. numbers on the system are formatted as 532xx. These are very similar to the radio numbers of the James City County Police (51xxx and several 53xxx). However, I have never heard any of the new 532xx numbers on known JCPD talkgroups. The 532xx series are probably handheld radios. In the James City County PD radios, a "2" in the third digit of the radio ID signifies a handheld. About 80% of the transmissions are encrypted. Since I heard someone ask to open the "sally port door", I believe it could be related be the Merrimac Center (Juvenile Detention) next to the Virginia Peninsula Regional Jail (talkgroups 1165 and 1166). Since the VPRJ uses radio ID numbers 632xx, I don't think the unknown talkgroups are assigned to the VPRJ.
