(3) The occupied bandwidth shall not be greater than that necessary for satisfactory transmission and, in any event, an emission appearing on any discrete frequency outside the authorized band shall be attenuated, at least, 43+10 log 10 (mean output power, in watts) dB below the mean output power of the transmitting unit. (e) For low power auxiliary stations operating in the bands allocated for TV broadcasting, the following technical requirements apply: (1) The power of the measured unmodulated carrier power at the output of the transmitter power amplifier (antenna input power) may not exceed the following: (i) 54–72, 76–88, and 174–216 MHz bands—50 mW (ii) 470–608 and 614–806 MHz bands—250 mW Test Procedure: The procedure used was EIA/TIA 603-C:2004. The receive was scanned from 30MHz to 5.0GHz.When an emission was found, the table was rotated to produce the maximum signal strength. An initial pre-scan was performed for in peak detection mode using the receiver. The EUT was measured for both the Horizontal and Vertical polarities and performed a pre-test three orthogonal planes. The field strength is calculated by adding the Antenna Factor, Cable Factor & Peramplifier. The basic equation with a sample calculation is as follows: Final Test Level =Receiver Reading+Antenna Factor+Cable Factor–Peramlifer Factor An initial pre-scan was performed in the 3m chamber using the spectrum analyser in peak detection mode. Quasi-peak measurements were conducted based on the peak sweep graph. The EUT was measured by Bilog antenna with 2 orthogonal polarities Remove the EUT and replace it with substitution antenna. A signal generator was connected to the substitution antenna by a non-radiating cable. The absolute levels of the Carrier Radiated Power and spurious emissions were measured by the substitution.

A maximum deviation of ±75 kHz is permitted when frequency modulation is employed. Test Procedure: Audio Frequency Response The RF output of the transceiver was connected to the input of FSP 30 with FM deviation module through sufficient attenuation so as not to overload the meter or distort the reading. An audio signal generator was connected to the audio input of microphone. The audio signal input level was adjusted to obtain 20% of the maximum rated system deviation at 1 kHz, and recorded as DEV REF . With the audio signal generator level unchanged, set the generator frequency between 100 to 5000 Hz. The transmitter deviations (DEV FREQ ) were measured and the audio frequency response was calculated as 20log10 [DEV FREQ / DEV REF ] Page 16 of 21

Modulation Limiting a) Adjust the transmitter per the manufacturer's procedure for full rated system deviation. b) Set the test receiver to measure peak positive deviation. Set the audio bandwidth for ≤0.25 Hz to ≥15,000 Hz. Turn the de-emphasis function off. c) Apply a 1000 Hz modulating signal to the transmitter from the audio frequency generator, and adjust the level to obtain 60% of full rated system deviation. d) Increase the level from the audio frequency generator by 20 dB in one step (rise time between the 10% and 90% points shall be 0.1 second maximum). e) Measure both the instantaneous and steady-state deviation at and after the time of increasing the audio input level. f) With the level from the audio frequency generator held constant at the level obtained in step e), slowly vary the audio frequency from 100 to 5000 Hz and observe the steady-state deviation. Record the maximum deviation. Page 17 of 21
