UNIT DESCRIPTION – The unit is a VHF FM transceiver operating in the 150 - 174 MHz frequency band. The radio unit is to be mounted in a remote location and controlled from a local mounted control head. The power on off, channel, function, and volume controls are located on the front of the control unit. The unit operates on 27-volt battery supply. The recommended antenna is a broadband blade or quarter wave whip. The unit operates with frequency modulation and is designed for voice communications. 2. INTENDED PURPOSE – These transceivers are utilized by the forestry service department and are intended to replace the wide band version currently in use for voice communications.

The power output shall be monitored and recorded and no adjustment shall be made to the transmitter after the test has begun, except as noted below: If the power output is adjustable, measurements shall be made for the highest and lowest power levels. Test Arrangement: The radio frequency power output was measured at the antenna terminal by replacing the antenna with a spectrum analyzer, 41-dB attenuation and cable. The spectrum analyzer had an impedance of 50Ω to match the impedance of the standard antenna. A HP 8591EM Spectrum Analyzer was used to measure the radio frequency power at the antenna port. The data was taken in dBm and converted to watts as shown in the following Table. Refer to Figures 1 through 3 showing the output power of the transmitter. Data taken per Paragraph 2.1046(a) and applicable parts of Parts 74 and 90. P dBm = power in dB above 1 milliwatt. Milliwatts = 10 (PdBm/10) Watts = (Milliwatts)(0.001)(W/mW) 40.0 dBm = 10 (40.0/10) = 10,000 mW = 10.0 Watts Results: FREQUENCYP dBm P mw P w 156.0040.010,00010.0 166.0040.310,91410.9 173.9939.69,1419.1 The specifications of Paragraph 2.1046(a) and applicable Parts of 74 and 90 are met.

These calculations are based upon a typical human figure as approximated below. The height is 5’ 8” (173 cm.) and the weight is 160 lbs. (72.6kg). The calculated absorption cross section for this figure is 143 cm squared. CALCULATED UNCONTROLLED, GENERAL POPULATION SAR S = PG/(4πR 2 ) Where S = power density in mw/cm 2 P = input power to antenna in mw. G = power gain of antenna R = distance from antenna in cm. The antenna structure is to be mounted outside the vehicle maintaining a minimum separation distance of 1 meter. For a minimum distance of 1000 centimeters and 10 watt (10,000mW) operation with a ¼ wave whip antenna, S is: S = 10000(1)/(4π(1000) 2 ) = 795.77E-6 mw/cm 2 For a body cross sectional area of 143 cm squared, (0.000795)(143) = 16.27 mw is absorbed. For a body mass of 72.6 kg, this is 0.01627/72.6 = 224.14E-6 watts/kg (0.000224 watts/kg) This is well within the .08 watts/kg limit prescribed by CFR 47 paragraph 2.1093.

The frequency generator was set to 1 kHz and injected into the audio input port of the EUT. The amplitude was adjusted to obtain 50% modulation at 1000 Hz. This level was then taken as the 0-dB reference. The frequency of the generator was then varied and the output level recorded while holding the input levels constant.
