Neiman Marcus DC New License

Neiman Marcus, located in the Mazza Gallerie in DC, was recently licensed for analog and DMR simplex on 451.3125, 451.3375, 456.3375, 464.2625, 464.3625, 464.5750, 464.9250, and 469.3625. (These frequencies seem to be licensed at most Neiman Marcus locations.)

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.

• 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.

NXDN in the DC Area

NXDN doesn't seem to be as popular in the DC area as DMR, but there are a few entities using it, and that number should increase in the future. Some of the identified users:

• Constitution Center, an office building in DC, uses four repeaters (452.0000, 461.9000, 462.2250, and 464.1000).
• Virgin America, an airline at Reagan National Airport, uses a repeater on 452.7625.
