  §  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.
