Sec.  24.135   Frequency stability.

   (a) The frequency stability of the transmitter shall be maintained within  ±
   0.0001 percent ( ± 1 ppm) of the center frequency over a temperature
   variation of −30 ° Celsius to +50 ° Celsius at normal supply voltage, and over
   a variation in the primary supply voltage of 85 percent to 115 percent of
   the rated supply voltage at a temperature of 20 ° Celsius.

   (b) For battery operated equipment, the equipment tests shall be performed
   using a new battery without any further requirement to vary supply voltage.

   (c) It is acceptable for a transmitter to meet this frequency stability
   requirement over a narrower temperature range provided the transmitter
   ceases to function before it exceeds these frequency stability limits.
