I was wondering why things are so noisy in the 460-470 MHz band. :P
The 460-470 MHz band is allocated to the non-Federal fixed and land mobile radio services on primary basis and to the Federal meteorological-satellite (space-to-earth) service on a secondary basis. The Federal agencies use this band (subject to mutual agreement and coordination with non-Federal users) for land mobile radio communication systems that are shared with State and local public safety partnering agencies for mutual aid responses, such as fire fighting, disaster preparedness, and law enforcement operations. On a secondary basis, the National Oceanic and Atmospheric Administration (NOAA) operates the Geostationary Operational Environmental Satellites (GOES) downlink in this band. Medical radiocommunications and telemetry equipment also operates in this band.
