Link to an amendment published at 68 FR 46966, Aug. 7, 2003.

(a)(1) The radio transmitter must meet the following requirements:

(2) The transmitter must have an antenna current meter.

(b) Survival craft non-portable receivers must meet the following requirements:

(1) The audio output must be one milliwatt at a signal to noise power ratio of at least 10 to 1, when the receiver is supplied through the following artificial antennas with the respective radio frequency signals:

Operating frequency, (kHz)Signal strength (microvolts)Modulation factorModulation (Hz)Artificial antenna5002000.340015 ohms resistance and 100 picofarads capacitance.83641,0000.340040 ohms resistance.

(2) When the receiver is adjusted for A2A or H2A emission on 500 kHz and 8364 kHz the noise power present in the output of the receiver must be determined with an unmodulated input signal of the indicated strength;

(3) The audio output of the receiver must be capable of at least 8 dB above one milliwatt at the rated loan impedance.

Effective Date Note:

At 68 FR 46966, Aug. 7, 2003, § 80.267 was removed effective October 6, 2003.
