§ 90.248   Wildlife and ocean buoy tracking.

   (a) The frequency bands 40.66-40.70 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 § § 90.205-90.217. In
   lieu thereof, the transmitters shall comply with the provisions in this

   (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 -30DEG to +50DEG 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 DEGC. 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

   (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 § 90.210(m).
