ALERT AM Technical Specifications 
The Overall System . . . 
  • ALERT AM Emergency Advisory Radio System & FloodsOperates according to Federal Communications Commission (FCC) rules, Part 90.242.
  • Achieves a maximum FCC signal level of 2.0 mV/m at 0.93 mile; effective coverage range is three to five miles (28-78 square miles).
  • Operates within the frequency range 530-1710 kHz (operation on 1710 kHz requires waiver).
  • Features audio bandwidth 5000 Hz per new FCC rules.
  • Uses primary programming: IP via Ethernet on LAN/WAN or by USB port as a backup.
  • Provides redundant operation with:
    • Touchtone telephone control via landline or on site or from remote locations.
    • An internal capability for 1,000 dynamic recorded messages and up to 3 hours of recordable time.
    • The ability to accommodate live broadcasts by telephone handset, locally at the station or remotely via dial-up telephone call in.
    • Automatic broadcasts of Emergency Alert System (EAS) and National Weather Service (NWS) 'All Hazard' alerts specific to targeted counties and event codes. When alerts are over, the system can be set to automatically return to normal programming.
    • Continuous broadcasts during programming changes.
    • Predetermined message playlists that key by external tone-alert receiver or relay closure.
    • Two-way redundant control of audio programming in the event of telephone line failure through use of a two-way (Simplex) radio channel with DTMF microphone. Automatic enablement if telephone control ceases to function. Has the same voice prompts and control protocols as when controlled by phone.

  • Includes all electronics, mounts, cable, wiring and connectors with a complete antenna system and factory-assembled groundplane.
Utilities . . . 
  • 110/220-volt AC, single phase/50/60 Hz, less than 1 amp AC operating current, 4-amp maximum AC charging current (20-amp breaker, nonGFI circuit). 
  • Standard business telephone line (“central office” type, shielded).

Workstation Audio Control 
Vertical Profile Antenna System (VP9000) 
Signal Measurement Radio Receiver to Test and Ensure FCC Compliance
Signal Booster (2X)
  • For up to double the efficiency/range of the station’s antenna, allowing the transmitter to run at less wattage or allowing the signal to have twice the signal intensity at a given distance.
  • Functions with upper-band (typ:1610-1700) antennas only (recommended for federal government agencies that do not have a signal intensity limitation; also for any operator in a challenging environment that requires maximum signal intensity to cut through woods, buildings and obstructions). (Note: local government licensees must seek a waiver of the FCC rules to allow a signal intensity above the standard 2.0 mV/m limitation.)
Broadcast Quality Audio Processor (HQ5.1) for increased audio intelligibility and range.
