THIS RADIO COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE CONDITION THAT THIS DEVICE DOES NOT CAUSE HARMFUL INTERFERENCE. Your Midland model G-9 UHF FM GMRS two-way radio is designed to provide you w ith line-of-sight communications for a range up to 5 miles. The model G-9 incorporates channels with 38 different CTCSS codes to provide the best in quiet communications. Also this radio offers scan, power save, 9 memory channels and a multifunction back-lighted liquid crystal display. This unit also incorporates VOX (voice operated transmit) that allows hands free use when the radio is equipped with certain accessories. 4 TIPS FOR GETTING THE MOST FROM YOUR G-9 Due to the band of operation (462 MHz) the G-9 provides communications that are virtually free of atmospheric interference (skip) that is common on lower frequency bands. Along with this and an antenna system that is very efficient, communications range is surprisingly good. Many times the limit to maximum possible range is environmental factors such as blockage caused by trees, buildings, hills, or other obstructions. If you find communication is not possible, many times this can be overcome by moving only a few feet to a new location. Range is greatly reduced while operating from a metal building or from a vehicle. Battery condition also affects range. The G-9 operates on rechargeable Ni-MH batteries or alkaline batteries. While this unit has been designed w ith gaskets for w ater res…

A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with an Audio Precision System One. The curves show compliance with Section 2.1047 and 95.633(b). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 95.633(b) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One on the Boonton 8220 modulation meter audio output. 4. Occupied_Bandwidth (Section 2.1047 and 95.629(a)of the Rules) Figure 4 is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.1049(c)(1) and consisted of a 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2697 Hz, the frequency of maximum response. 2 C.

SPURIOUS EMISSIONS AT THE ANTENNA TERMINALS Not applicable, permanently attached antenna. F. MEASUREMENTS OF SPURIOUS RADIATION (Section 2.1053, 95.635(b)(7) of the Rules) Field intensity measurements of radiated spurious emissions from the G-9 were by substitution made with a Tektronix 494P spectrum analyzer using Singer DM-105A calibrated test antennae for the measurements to l GHz, and EMCO 3115 horn from 1 GHz to 5 GHz. The transmitter with the normally supplied antenna was located on an open area test site 3 meters from the test antenna. Supply voltage was a power supply with a terminal voltage under load of 6.0 Vdc. The transmitter and test antenna were arranged to maximize pickup. Both vertical and horizontal test antenna polarization were employed.
