Sec.  22.880   Information exchange.

   (a) Prior notification. Public safety/CII licensees may notify a commercial
   aviation  air-ground  system  licensee that they wish to receive prior
   notification of the activation or modification of a commercial aviation
   air-ground  system  ground station site in their area. Thereafter, the
   commercial aviation air-ground system licensee must provide the following
   information to the public safety/CII licensee at least 10 business days
   before a new ground station is activated or an existing ground station is
   modified:

   (1) Location;

   (2) Effective radiated power;

   (3) Antenna manufacturer, model number, height above ground level and up
   tilt angle, as installed;

   (4) Channels available for use.

   (b) Purpose of prior notification. The prior notification of ground station
   activation  or modification is for informational purposes only: public
   safety/CII licensees are not afforded the right to accept or reject the
   activation of a proposed ground station or to unilaterally require changes
   in its operating parameters. The principal purposes of prior notification
   are to:

   (1)  Allow  a public safety licensee to advise the commercial aviation
   air-ground system licensee whether it believes a proposed ground station
   will generate unacceptable interference;

   (2)  Permit  commercial aviation air-ground system licensee(s) to make
   voluntary changes in ground station parameters when a public safety licensee
   alerts them to possible interference; and

   (3) Rapidly identify the source if interference is encountered when the
   ground station is activated.
