Mobile Radio Message Inc

A single dial tone rings somewhere just off 26th. Mobile Radio Message Inc broadcasts straight through the city’s hum on 260 Madison Avenue.

Niche formats—emergency tones, public-safety feeds, marine weather—travel the same FM band and dispatch networks your walkie might miss in a canyon of glass and steel. No voice clings too long in their studio. Senders expect static-free fidelity; receivers get it without a second window open.

Near Penn Station and the garment district’s manic sidewalks, the signal punches farther than a rooftop whip because the engineers patch in repeaters upstate. A bail bondsman in Tribeca keeps a T-shirt box of spare crystals for when the urge to transmit gets quiet for a few blocks.

Swing left at the park’s iron fence, check the no left turns sign by the loading docks, and park once—you’ll find the map at 260 Madison Avenue. To coordinate the next patch, call (212) 949-9400 and listen for the tone.
