Be sure to number or identify your answer with the corresponding question. If you are referring to another document, be sure to give the page number and paragraph reference where your response can be found. Thank you for your reply and revised exhibit. However, based upon our review of this application we still have the following questions (blue font): 1. - 2. Power settings: Please describe whether the power is switchable or variable from Low to High power setting. Please revise test report to include this information. a) It is understood that only the manufacturer will set the power to high and low. Please explain whether the radio has a switch so the user can select either 3.13W or 1W. b) Can the manufacturer program the power anywhere between 3.13W and 1W (example 2 Watt radio for user A and 3.13 W to user B, etc.) c) If the radio is tunable from 1W to 3.13W by the manufacturer, then a grant note will be added to the grant conditions. d) If the radio is switchable to 3.13 or 1W, then 3 line items will be added on the grant with a rated power of 1W. e) If the radio is switchable to 3.13 or 1W, please provide in the test report the measured output power for the low power settings. 3. Part 90.203(e): The manual page 13/15 indicates that users can program the channel/ frequency and the desired power setting (low and high). Please provide an attestation for compliance with this section. Section 90.203(e): Except as provided in paragraph (g) of this section, transmitters designed to operate above 25 MHz shall not be certificated for use under this part if the operator can program and transmit on frequencies, other than those programmed by the manufacturer, service or maintenance personnel, using the equipment's external operation controls. a) Please provide an attestation from the applicant. 4. - 5. Part 2.1093 - RF exposure and manual exhibits: The applicant is supplying a belt-clip for operation at a separation distance closer than 2.5cm from the body. This conflicts with the instruction to operate at >2.5cm. The equation used in this exhibit is not appropriate for a P.T.T device with a belt-clip providing a separation distance from the body of less than 2.5cm. The following equation should be used for determining whether or not SAR is required to qualify for TCB approval: Low Threshold = (375/fGHz) mW, d < 2.5 cm. SAR testing is required for this device. Alternatively, please provide a side view photo of the belt-clip showing a separation distance > or = 2.5cm from the back of the radio (not the antenna). a) Manual - Page 1 of 15 : It is indicated the following: “ Body-worn Operation: Always place the radio in an BFDX approved holder, case, or body harness for this product” This is conflicting with previous reply. This device was designed to be used with a belt-clip (see screws on back of device for belt-clip accessory). Manual - page 3 of 15: Instructions 9. “if you wear a portable two way radio on your body, ...”. The FCC requires showing evidence of a belt-clip providing a separation distance of at least 2.5cm in order to qualify for the low threshold for d >2.5cm. Even though the manufacturer is not supplying a belt-clip, this device is supplied with an external microphone/speaker connector for connection to a headphone and it has VOX capability. This device is expected to be body-worn and the user has not mean to p…

CIRCUIT DESCRIPTION 1.Frequency configuration The receiver utilizes double conversion. The first IF is 45.05MHz and the second IF is 455kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Fig. 1 shows the frequencies Fig. 1 Frequency configuration 2.Receiver The receiver is double conversion superheterodyne, designed to operate in the frequency range of 430 to 470MHz. The frequency configuration is shown in Fig. 1. 1) Front-end RF amplifier The signal coming from the antenna passed through the transmit/receive switching diode circuit, (D1, D2, D3 and D4), passed through a BPF (L44 and L45), and is amplified by the RF amplifier (Q34). The resulting signal passed through a BPF (L41, L42 and L43) and goes to the mixer. These BPFs are adjusted by variable capacitors (D13, D14, D15, D16 and D17). The input voltage to the variable capacitor is regulated by voltage output from the microprocessor (U9). (See Fig.2) Fig. 2 Receiver section configuration 2) First Mixer The signal from the front-end is mixed with the first local oscillator signal generated in the PLL circuit by Q33 to produce a first IF frequency of 45.05MHz. The resulting signal passed through the MCF (XF2 and XF2) to cut the adjacent spurious and provide the optimum characteristics, such as adjacent frequency selectivity. 3) IF Amplifier Circuit The first IF signal is passed through a four-pole crystal filter (XF2 and XF3) to remove the adjacent channel signal. The filtered first IF signal is amplified by the first IF amplifier (Q4) and then applied to the IF system IC (U7). The IF system IC provides a second mixer, second local oscillator, limiting amplifier and quadrature detector. The second mixer mixes the first IF signal with the 45.05MHz of the second local oscillator (44.595MHz) and produces the second IF signal of 455kHz. The second IF signal is passed through the ceramic filter (XF1) to remove the adjacent channel signal. The filtered second IF signal is amplified by the limiting amplifier and demodulated by the quadrature detector with the ceramic discriminator (CD1).The demodulated signal is routed to the audio circuit. 4) Audio Amplifier Circuit The demodulated signal form U7 is amplified by U10 (1/4), low-pass filtered by U10 (2/4), high-pass filtered by U10 (3/4 and 4/4), high-pass filtered by U5 (4/4), and de-emphasized. The signal then goes through an noise filter U11,an AF volume control (VR1), and is routed to an audio power amplifier (U1) where it is amplified and output to the speaker. 5) Squelch Part of the AF signal from the IC enters the FM IC (U7) again, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level. The DC signal from the FM IC goes to the analog port of the microprocessor U9. U9 determines whether to output sounds from the speaker by checking wheter the input voltage is higher or lower than the preset value. To output sounds from the speaker, U9 sends a high signal to the MUTE and AFCO lines and turns U1 on through Q30, Q17, Q7, Q21, Q43 and Q44. (See Fig. 3) Fig. 3 AF Amplifier and squelch 6) Receive Signalling (QT/DQT) 300Hz and higher audio frequencies of the output signal from IF IC are cut by a low-pass filter U5 (1/4 and 2/4). The resulting signal enters the microprocessor (U9). U9 determines whether the QT or DQT matches the preset value, and controls the MUTE and AFCO and the speaker output sounds according to the squelch results. 3.PLL frequency synthesizer The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission. 1) PLL The frequency step of the PLL circuit is 5 or 6.25kHz. A 13MHz reference oscillator signal is divided at U3 by a fixed counter to produce the 5 of 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q2,then divided in U3 by a dual-module programmable counter. The divided signal is compared in phase with the 5 of 6.25kHz reference signal in the phase comparator in U3. The output signal from the phase comparator is filtered through a low-pass filter and passé to the VCO to control the oscillator frequency. Fig. 4 PLL circuit 2) VCO The operating frequency is generated by Q5 in transmit mode and Q6 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D5 and D6 in transmit mode and D7and D8 in receive mode). The T/R pin is set high in transmit mode causing Q19 and Q23 to turn Q6 off, and turn Q5 on. The T/R pin is set low in receive mode. The outputs from Q5 and Q6 are amplified by Q2 and sent to the buffer amplifiers. 3) Unlock Detector If a pulse signal appears at the LD pin of U3, an unlock condition occurs, and the DC voltage obtained from U3 cause the voltage applied to the microprocessor to go low. When the microprocessor detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal. 4.Transmitter 1) Microphone Amplifier The modulation signal from the microphone is amplified by U2 (1/2),passed through a preemphasis circuit, and amplified by the other U2 (2/2) to perform IDC operation. The signal then passed through a low-pass filter (splatter filter) (Q13 and Q14) and cuts 3kHz and higher frequencies. The resulting signal goes to the VCO through the VCO modulation terminal for direct FM modulation. (See Fig. 5) Fig. 5 Transmit audio QT/DQT 2) QT/DQT encoder A necessary signal for QT/DQT encoding is generated by U9 and FM-modulated to the PLL reference signal. Since the reference OSC does not modulate the loop characteristic frequency of higher, modulation is performed at the VCO side by adjusting the balance. 3) Drive and Final Amplifier The signal form the T/R switch (D101 is on) is amplified by the pre-drive (Q12 and Q9) and drive amplifier (Q10) to 500mW. …
