This equipment meets the requirements of the FCC Rules, Parts 90.203(e) and (g), as applicable. Programming of this products transmit frequencies can be performed ONLY by the manufacturer or by service or by maintenance personal. The operator can’t program transmit frequencies using the equipment’s external operation controls. This is to certify that the requirements of 47 CFR Part 90.203(j)(4) and (5) spectrum efficiency are met by the TYT ELECTRONICS CO., LTD demonstrated by the tests conducted on the sample radio provided. The tests show that the 4FSK data rate is in accordance with ETSI TS 102 361-1, that is 9600 bits per second in a 12.5 kHz bandwidth to satisfy the data rate requirement of 4800 bits per second per 6.25 kHz of channel bandwidth (7K60F1D emissions). Additionally the radio uses the AMBE+2 half-rate vocoder to compress 60 ms of normal bursts are sent in alternate 30 ms TDMA slots and so comply with the equivalence of one voice channel per 6.25 kHz bandwidth (7K60F1W emission). Additionally the radio also meets the requirement of one voice channel per 12.5 kHz of channel bandwidth for analogue speech (11k0F3E emission).

Modulation Characteristics 9.1 Provisions Applicable According to FCC§2.1047 and §90.207, for Voice Modulation Communication Equipment, the frequency response of the audio modulation circuit over a range of 100 to 5000Hz shall be measured. 9.2 Measurement Procedure  Modulation Limit 1. Test layout and build equipment as shown below. 2. adjust the audio input for 60% of rated system deviation at 1kHz using this level as a reference (0dB). 3. Vary the input level from –20 to +20dB. 4. Record the frequency deviation obtained as a function of the input level. 5. Repeat step 2 with input frequency changing to 300, 1000, 1500 and 3000Hz in sequence.  Audio Frequency Response 1. Test layout and build equipment as shown below. 2. Adjust the audio input for 20% of rated system deviation at 1 kHz using this level as a reference (0 dB). 3. Vary the Audio frequency from 100 Hz to 10 kHz and record the frequency deviation. 4. Audio Frequency Response = 20log10 (Deviation of test frequency/Deviation of 1 kHz reference). 9.3 Measurement Setup Report No.: AGC02931231004FR01 Page 48 of 73 9.4 Measurement Result By DC Power A.
