CIRCUITS TO SUPPRESS SPURIOUS RADIATION, LIMIT MODULATION AND CONTROL POWER 1) VCO section The oscillator circuit formed by L303, D305 and D306 generates transmitter frequencies. Then this signal is fed to the 3-stage of amplifiers, buffer amplifier Q302, pre,-ampufler IC301 and post amplifier Q303 and lead to the final amplifier. 2) PLL section Basically, the circuit description is the same as Rx. PLL IC inclusive with pre-scaller IC205 compares the phase between the VCO signal and reference oscillator frequency (12.00NMz) by method of dividing the frequency, and produces VCO control signal. Then this VCO control signal is fed to the charge pump, consisting of Q206, Q207 and Q208, and fed to the LPF. The supply voltage of charge pump is amplified by IC206 (approx. 15V) to achieve greater C/N ratio. 3) Modulator section The modulation signal is fed to both VCO and the reference oscillator (TCVXO), this permits a very flat modulation characteristics against low frequency (DC). This is the advantage when KG510 is used for POCSAG transmitter. 4) Tx younger section The VCO signal is amplified by Q215 and Q216 to achieve 250mW. But VHF bands (136-174MHz) has only stage of amplifier Q215 to achieve l00mW. 5) PA section The signal from younger stage is fed to PM510 and Q510 (VHF bands have no Q501) to achieve 50W output power. Then, signal is fed to the LPF to eliminate the harmonics spurious frequencies. An APC circuit formed by IC502, IC503, Q504 and Q505 stabilizes the output power at the set level. An IC501 protects PM501 and Q501 from the reverse power caused by the unmatched aerials. CIRCUITS TO SUPPRESS SPURIOUS RADIATION, LIMIT MODULATION- AND CONTROL POWER FCC ID: O6E713050B

ALIGNMENT PROCEDURES KYODO KG510 BASE/REPEATER RECEIVER PART 1) BPF-1 and BPF-2 alignment Connect the signal generator to the Rx antenna connector of KG510. Align the BPF-1 and BPF-2 to obtain the maximum sensitivity. For better alignment, if yo u have spectr um a nal yzer a nd trac king ge nerator, co nnect the trac king ge ne- rator to the Rx antenna connector and pick up the output signal from J101 to connect spectrum analyzer. Align the BPF-1 and BPF-2 to have cover the desired bandwidth of receiving frequencies. 2) FVR101 alignment This is to adjust the squelch tihgt level. 3) VCO alignme nt Set the VCO voltage at 10.5V by L303 at the highest receiving frequency. TRANSMITTER PART 1) FVR201 alignment This potentiometer determines the modulation level. Carefully aling this potentiometer to obtain flat deviation from the lowest to the highest frequency installed n the transmitter. 2) FVR202 alignment This potentiometer determines the low frequency (below 300Hz) deviation. When POCSAG, CTCSS or DCS are used, necessary to align to have enough deviation at low freque nc y. 3) FVR203 alignment This potentiometer sets the maximum deviation, normally set at 5KHz. 2KHz or 2.5KHz deviation for narrow spacing can be set by programming software. 4) FVR204 alignment This is to adjust the transmitter output power. 5) VCO alignme nt Set the VCO voltage at 10.5V at the highest channel frequency. LOGIC PART 1) FVR1 alignment This potentiometer is to obtain 600 ohm 0dBm output of the RF signal. 2) FVR2 alignment This is to set the deviation level when KG510 is used for a repeater. 3) FVR3 alignment This is to set the Tx output power level indicating on the LCD. 1) FVC1 alignment This is to shift the CPU clock frequency when necessary. A beat interference sometimes happens at certain frequency. In such case, shifting the CPU clock frequency may eliminate the interference. FRONT CONTROL PANEL PART 1) VR401 alignment This is a volume controller. 2) VR402 alignment This is a squelch level controller. 3) FVR401 alignment This is to set the HI-POWER-LEVEL of the Tx output power. 4) FVR402 alignment This is to set the LO-POWER=LEVEL of the Tx output power. 5) FVR403 alignment This is to set the contrast of the LCD back light.

A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 3. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF POWER OUTPUT (Paragraph 2.985(a) of the Rules) RF power output was measured with a Bird 4421 RF power meter and a Bird 8325 power attenuator as a 50 ohm dummy load. Maximum power measured was 70 watts; and with internal adjustments minimum power was 25 watts. D. MODULATION CHARACTERISTICS 1. 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 a Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figures 2a and 2b for wide or narrow channel operation respectively, using a Boonton 8220 modulation meter. Signal level was established with a Audio Precision System One TRMS voltmeter. The curves show compliance with paragraphs 2.987(b), and 90.211(c). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 90.211(d)(1) 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 selective voltmeter on the Boonton 8220 modulation meter audio output. 3 D. MODULATION CHARACTERISTICS (Continued) 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4) and 90.210(d) of the Rules) Figures 4a, 4b, 4c and 4d are plots of the sideband envelope of the transmitter for both 70 and 25 watt output taken with a Advantest R3361A spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2450 Hz, the frequency of maximum response. Measured modulation under these conditions was 3.9 kHz, or 1.9 kHz for 25 or 12.5 kHz channelization respectively. For the 12.5 kHz channelization, RBW was 100 Hz, VBW 100 Hz, max hold, multiple scan per 90.210(d)(4). All plots have unmodulated carrier as 0 dBm reference. 4 FIGURE 1 MODULATION FREQUENCY RESPONSE MODULATION FREQUENCY RESPONSE FCC ID: O6E713050B FIGURE 1 5 FIGURE 2a AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E713050B FIGURE 2a Wideband (5 kHz) 6 FIGURE 2b AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E713050B FIGURE 2b Narrow band (2.5 kHz) 7 FIGURE 3 AUDIO LOW PASS FILTER RESPONSE AUDIO LOW PASS FILTER RESPONSE FCC ID: O6E713050B FIGURE 3 8 FIGURE 4a OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency more than 50% up to and including 100% of the 25 authorized bandwidth, 20 kHz (10-20 kHz) On any frequency more than 100%, up to and including 250% of the 35 authorized bandwidth (20-50 kHz) On any frequency removed from the assigned frequency by more 43+10LogP = 61 than 250% of the authorized (P = 70 W) bandwidth (over 50 kHz) OCCUPIED BANDWIDTH (70 W) FCC ID: O6E713050B FIGURE 4a (5 kHz) 9 FIGURE 4b OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency more than 50% up to and including 100% of the 25 authorized bandwidth, 20 kHz (10-20 kHz) On any frequency more than 100%, up to and including 250% of the 35 authorized bandwidth (20-50 kHz) On any frequency removed from the assigned frequency by more 43+10LogP = 57 than 250% of the authorized (P = 25 W) bandwidth (over 50 kHz) OCCUPIED BA…
