Linked Capacity Plus Systems in North-Central VA

A couple of communications providers have built Linked Capacity Plus systems in north-central Virginia. Communication Specialists has one with sites in Fredericksburg, Independent Hill, and King George. There is also a strong possibility of another site in Warsaw (Richmond County). The company is also licensed for a site in Madison County, but this site may actually belong to Teltronic. As far as is known, all transmissions on the Communication Specialists system use Privacy. The company has coverage maps for its network.

Teltronic has a site in Linden (Fauquier County). A group seen on this site was also seen on the supposed Madison County site of Communication Specialists. (This is why the ownership of the Madison site is in question.) The group seen did not use Privacy. Teltronic has a coverage map for its Washington-Baltimore network, but it does not show a site in Madison County.

Baltimore Recent Finds

Notes from a trip to Baltimore last Saturday:
  • A couple more groups were found on the Johns Hopkins Hospital Capacity Plus system.
  • Johns Hopkins University appears to be using MOTOTRBO conventional repeaters, probably linked with IP Site Connect. Group 10 on these repeaters is security and group 40 is a Baltimore Police simulcast (unknown which District).
  • The recently-opened Horseshoe Casino is using a five-frequency Capacity Plus system. Many groups were identified.
  • The Maryland Zoo in Baltimore appears to have abandoned their UHF-T repeaters in favor of a Capacity Plus system. Only one group was identified in brief listening.
