Sec.  90.248   Wildlife and ocean buoy tracking.

   (a) The frequency bands 40.6640.70 MHz and 216–220 MHz may be used for the
   tracking of, and the telemetry of scientific data from, ocean buoys and
   animal wildlife.

   (b) Transmitters operating under the provisions of this section are not
   subject to the technical standards contained in  Sec.  Sec. 90.20590.217. In lieu
   thereof, the transmitters shall comply with the provisions in this section.

   (c) Classes of emission are limited to N0N, A1A, A2A, A2B, F1B, J2B, F2A,
   F2B, and/or F8E.

   (d) The authorized bandwidth shall not exceed 1 kHz.

   (e) Frequency stability. (1) For transmitters operating in the 40.66–40.70
   MHz frequency band, the frequency stability shall be sufficient to ensure
   that, at the carrier frequency employed, the sum of the authorized bandwidth
   plus the bandwidth required for frequency stability are confined within this
   band.

   (2) In the 216–220 MHz frequency band, transmitters shall employ a minimum
   frequency stability of 0.005 percent (50 parts per million). The carrier
   frequency shall be selected to ensure that the sum of the authorized
   bandwidth plus the bandwidth required for frequency stability are confined
   within this band.

   (3) The frequency stability standards shall be met over a temperature range
   of −30 ° to +50 ° centigrade at normal supply voltage and for a variation in
   the primary supply voltage from 85% to 115% of the rated supply voltage at a
   temperature of +20  °C. For battery operated equipment, the equipment tests
   shall be performed using a new battery.

   (f) The maximum peak transmitter output (carrier) power shall not exceed 1
   milliwatt for airborne wildlife applications, 10 milliwatts for terrestrial
   wildlife applications or 100 milliwatts for ocean buoys.

   (g) Emissions appearing outside of the authorized bandwidth shall be
   attenuated below the carrier power by at least 26 dB, following the
   procedures specified in  Sec. 90.210(m).
