Watch Dog Timer 2.2Product Description The Kyodo KG510 transceivers represent a quantum advance on the previous rugged & time proven KG110 transceiver. They comprise of separate modules all housed within one 2RU equipment cabinet. The receiver, the transmitter, and the PA Unit are each enclosed within their own diecast housing, that are then directly mounted on the large upper heat-sink. A μProcessor controlled interface module controls the channel selection, LCD Display, timers, interfaces, and signalling features. Models are available for all FM commercial and military frequency bands from 30 MHz to 520 MHz, with channel selectable 12.5, 20, 25, or 30KHz channel spacing arrangements. The RF Power Output is 70 Watt s on a continuous duty basis. The CTCSS module supports all EIA tones. All tones and different encode and decode tones can be set on a per channel basis during radio programming. The KG510 includes 5 tone Selective Calling encoder/decoder with non-predictive decoder, as well as a DTMF encoder, and voice encryption. It supports normal all channel scanning and programmed channel scanning for base use. The KG510 is fitted with a large full dot matrix LCD that is used to display the Channel Numbers & Names, frequency & tone programmed information, and signalling information. All user interface keys and knobs are conveniently located on the front of the radio. All user entered functions are easily activated in a logical manner via the keypad. The KG510 is supplied with an "N" Type connector for the transmitter, and a TNC Connector for the Receiver to allow easy connection to the diplexer or feeder cables. The rear panel includes a 9 way D sub connector for fitment of an external shared tone panel. Also included is a 25 way D sub connector that enables external interface to other radios or control equipment.

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.

With a nominal battery voltage of 13.6 VDC, and the Transmitter properly adjusted, the RF output measures: INPUT POWER: (13.7V)(13.0A) = 178.10 Watts OUTPUT POWER: 70 Watts METHOD OF MEASURING RF POWER OUTPUT TRANSMITTER RESISTIVE LOAD POWER METER APPLICANT: MIDLAND RADIO CORPORATION FCC ID: MMA714050C REPORT #: T:\M\MidlandRadio_MMA\1158UT2\1158UT2TestReport.doc Page 4 of 23 2.1047(a)(b) Modulation characteristics: AUDIO FREQUENCY RESPONSE The audio frequency response was measured in ac- cordance with TIA/EIA Specification 603. The audio frequency response curve is shown on page 5. The audio signal was fed into a dummy microphone circuit and into the microphone connector. The input required to produce 30 percent modulation level was measured. 2.1047(b) Audio input versus modulation The audio input level needed for a particular per- percentage of modulation was measured in accor- dance with TIA/EIA Specification 603. The audio input curves versus modulation are shown in pages 6-7. Curves are provided for audio input frequen cies of 300, 1000, and 2500 Hz. Post Limiter Filter The filter must be between the modulation limiter and the modulated stage. At any frequency between 3 & 20 kHz the filter must have an attenuation of 60log (f/3) greater that the attenuation at 1KHz. See the plot; page 8.
