This manual is intended for use by experienced technicians familiar with similar types of commercial grade communications equipment. It contains all required service information for the equipment and is current as of this publication date. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions, which are issued as required. ORDERING REPLACEMENT PARTS When ordering replacement parts or equipment information, the full part identification number should be included. This applies to all parts : components, kits, and chassis. If the part number is not known, include the chassis or kit number of which it is a part and a sufficient description of the required component, for proper identification. 2 TK-790/(B)/H(B) GENERAL PRE-INSTALLATION CONSIDERATIONS 1. UNPACKING Unpack the radio from its shipping container and check for accessory items. If any item is missing, please contact KENWOOD immediately. 2. LICENSING REQUIREMENTS Federal regulations require a station license for each radio installation (mobile or base) be obtained by the equipment owner. The licensee is responsible for ensuring transmitter power, frequency, and deviation are within the limits permitted by the station license. Transmitter adjustments may be performed only by a licensed technician holding an FCC first, second or general class commercial radiotelephone operator’s license. There is no license required to install or operate the radio. 3. PRE-INSTALLATION CHECKOUT 3-1. Introduction Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation. 3-2. Testing The radio should be tested complete with all cabling and accessories as they will be connected in the final installation. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. QT equipment operation should be verified. 4. PLANNING THE INSTALLATION 4-1. General Inspect the vehicle and determine how and where the radio antenna and accessories will be mounted. Plan cable runs for protection against pinching or crushing wiring, and radio installation to prevent overheating. 4-2. Antenna The favored location for an antenna is in the center of a large, flat conductive area, usually at the roof center. The trunk lid is preferred, bond the trunk lid and vehicle chassis using ground straps to ensure the lid is at chassis ground. 4-3. Radio The universal mount bracket allows the radio to be mounted in a variety of ways. Be sure the mounting surface is adequate to support the radio’s weight. Allow sufficient space around the radio for air cooling. Position the radio close enough to the vehicle operator to permit easy access to the controls when driving. 4-4. DC Power and wiring 1. This radio may be installed in negative ground electrical systems only. Reverse polarity will cause the cable fuse to blow. Check the vehicle ground polarity before installation to prevent wasted time and effort. 2. Connect the positive power lead directly to the vehicle battery positive terminal. Connecting the Positive lead to any other positive voltage source in the vehicle is not recommended. 3. The cable provided with the radio is sufficient to handle the maximum radio current demand. If the cable must be extended, be sure the additional wire is sufficient for the current to be carried and length of the added lead. 5. INSTALLATION PLANNING – CONTROL STATIONS 5-1. Antenna system Control station. The antenna system selection depends on many factors and is beyond the scope of this manual. Your KENWOOD dealer can help you select an antenna system that will best serve your particular needs. 5-2. Radio location Select a convenient location for your control station radio which is as close as practical to the antenna cable entry point. Secondly, use your system’s power supply (which supplies the voltage and current required for your system). Make sure sufficient air can flow around the radio and power supply to allow adequate cooling. SERVICE This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and alignment procedures contained in this manual. 3 TK-790/(B)/H(B) SYSTEM SET-UP Before Reading About System Set-up The TK-790(B)/H(B) is a transceiver main unit (without a panel or speaker) that you complete by adding options.

(2) Press the [RPT] Key, then both the VHF and UHF units move to the repeater channel, and enter Repeater mode. Displays of both heads show “REPEATER”. (3) If one unit receives a proper signal, the other unit will start transmitting (repeating). (4) If the signal stops, the repeat action will stop. If one of the units detects another signal, the repeat action will restart. (5) Press [RPT] again, both units return to their previous channels, and exit the Repeater mode. However, during the repeating mode, pressing [RPT] has no effect. 24. Emargency Call (EMG) If the [EMG] Key is held down, the RADIO enters the Emergency Mode. In the Emergency Mode, the channel changes to the “Emergency Channel (set by the FPU)” internally. The display depends on “Emergency Channel Display” setting, and the Emergency Call (None, DTMF, MSK or ANI board) is transmitted. If “ANI Board” is selected for the Emergency Type, turn the transceiver off, then turn it on again to recover “Normal Mode”. If “ANI Board” is not selected for the Emergency Type, press and hold [EMG] key to recover “Normal Mode”. TK-790/(B)/H(B) OPERATING FEATURES 2Tone signalling opens the squelch only when the RADIO receives a proper 2Tone code that is the same as the pre-programmed 2Tone for the channel. When the RADIO receives a 2Tone code, the CALL icon flashes. If Transpond has been programmed, the RADIO will return an acknowledgment signal automatically after receiving the 2Tone code. If Call Alert has been programmed, an Alert Tone sounds after receiving a 2Tone code. You can configure “Normal” (an alert tone beeps once) or “Continuous” (an alert tone beeps every 5 seconds) for the Call Alert. Unmute condition is canceled and the CALL icon goes off when ; (1) pressing the [MON] Key, (2) hanging the microphone on its hook, (3) muting continues for 10 seconds. (If “Auto Reset” has been programmed) 27. DTMF Signalling 29-1. AND The audio is unmuted when the RADIO receives the correct QT/DQT and 2Tone/DTMF. After transmitting, 2Tone/ DTMF will be canceled. 29-2. OR The audio is unmuted when the RADIO receives the correct QT/DQT. 2Tone/DTMF is used just as an individual call or group call. 30.

CM coupler is a line for detecting traveling and reflected waves. Traveling waves are detected by D5 and fed through the APC control to differential amplifiers Q5, which compare the signal level with the reference voltage of PC tuned. The output is amplified by DC amplifier Q1 to control APC DC amplifier Q2. Q1 controls the power supply voltage for the power module, keeping the transmitter output constant. To protect the transmitter power amplifier stages, there is protection circuit, against abnormal antenna loading. If an abnormal antenna load is connected the reflected wave level increases.

Final amplifier section (X45) : TK-790H(B) The signal from the DO terminal of the CN1 is applied to drive the power module, and the output is divided into two signals which are amplified by Q6 and Q7. The signals are mixed and the resulting signal is fed through CM coupler, transmit/receive switching relay ; K1, and the low-pass filter to the antenna connector. CM coupler is a line for detecting traveling and reflected waves. Traveling waves are detected by D1, D3 and fed through the APC control to differential amplifiers Q5, which compare the signal level with the reference voltage of PC tuned. The output is amplified by DC amplifier Q4 to control APC DC amplifier Q3. Q4 controls the power supply voltage for the power module, keeping the transmitter output constant.

Receiver Circuit Item Incoming signals from the antenna pass through a lowpass filter in the final unit of the transmitter system, and are switched to the front-end of the receiver system via a receive/transmit switch (switching diode D3 and D4 : TK-790/ (B), switching relay K1 : TK-790H(B)). The signal is then passed through an antenna matching coil. After passing through the BPF (L.C filter), it is amplified by the RF amplifier (Q101). The tuned varactor BPF (L110~112) is then passed, and it enters the 1st mixer. The 1st mixer use a double balanced mixer (A101). The DBM is an excellent IM (intermodulation distortion) and image. The 1st mixer mixes the signal with the 1st local oscillator frequency and converts it to the 1st IF (44.85MHz). The signal is amplified by the 1st IF amplifier 1 (Q102). The signal then passes through two monolithic crystal filters (XF101 : Wide, XF102 : Narrow) to remove unnecessary nearby frequency components. The signal from the XF101 or XF102 is used as the 1st IF signal. The 1st IF signal is amplified by 1st IF amplifier 2 (Q107) and fed into IC101 in the FM IF IC. The IF signal is then mixed with the 2nd local oscillator frequency of 45.305MHz to generate the 2nd IF of 455kHz. The 455kHz signal is then passed through a ceramic filter (CF101, CF103 : Wide, CF102, CF104 : Narrow) and fed back into IC101 for additional amplification. The AF signal output from IC101 then passes through the control unit's HPF and D/A converter IC. After entering the AF power amplifier (IC522), the signal is output from the speaker.

Each oscillators are switched by turning the source line for Q307, Q308 and Q309 on and off. The signal output of the VCO is amplified by the buffer amplifier Q310 and divided into two signals which one is amplified by Q312 and the other is done by Q311. The signal from Q312 passes through D306 which is transmit/receive switch, is amplified by Q201 and Q204, and is output from the CN203. The signal from Q311 passes through the low-pass filter and is applied to IC301 which is PLL frequency synthesizer with VCXO ; X301. The VCXO of which the frequency stability is within 2.0ppm (temperature range of –30 to +60°C) generates 16.8MHz. The PLL-IC consists of three modulus prescaler, fractional divider, reference divider, digital phase comparator with charge pump output. This PLL-IC is Fractional-N type synthesizer and performs is 40 or 50 or 60kHz reference signal which is eighth of the channel step (5 or 6.25 or 7.5kHz). The input signal from the pins 5 and 8 of the PLL-IC is divided down to the 40 or 50 or 60kHz and compared at digital phase comparator. The pulsed output signal of the digital phase comparator is applied to the charge pump and transformed into DC signal. The DC signal from the pin 14 of the PLL-IC passes through the active low-pass filter (loop filter), is applied to the VCO and controls to keep the frequency of the VCO. The serial data (DT, CP, EP) from the microprocessor IC516 is input to the PLL-IC. And PLL lock condition is always monitored by the pin 28 (UL) of IC516. SQ close SQ open Preset value RSSI voltage 5. VCO/PLL Circuit The output from IC101 enters FM IC again, then passed through a band-pass filter. The noise component output from IC101 is amplified by Q109 and rectified by D103 to produce a DC voltage corresponding to the nose level. The DC voltage is sent to the analog port of the CPU (IC516/pin 27). And IC101 output a DC voltage (RSSI) corresponding to the input of the IF amplifier. The CPU reads the RSSI signal via pin 26. IC101 determines whether to output sounds from the speaker by comparing the input voltage of pin 27 with the present value. Only during scan, the RSSI DC voltage is used together with the noise wave detection pin's DC voltage (pin 27). SQ voltage 3.

Power supply circuit D507 is a protection diode for the excess voltage 1) Turning the transceiver on/off with a power switch. Each time you press the power switch, the IC501 output is alternated. The output is feed through Q501, Q503 to turn Q519 on. The power source is always supplied to the IGN terminal. If 24V DC is supplied to the transceiver by mistake, Q502 is turned on then Q503 and Q519 are turned off to protect the transceiver (turned off). 2) Turning the transceiver on with a power switch, then turning the transceiver off with the Timed Power Off (TPO) function. POF is controlled by CPU’s TPO function. POF is to turn the transceiver off. The POF logic signal is feed through Q507 and Q506 then 8 pin of IC501 to turn the transceiver off. 3) Turning the transceiver on with IGN SENS, then turning the transceiver off with TPO function. If IGN is turned on, Q543 and Q542 are turned on then the IC501 detects the change. IC501 outputs the signal to turn Q541 off, then Q503 and Q519 are turned on. When POF is detected by 6 pin of IC501, Q541 is turned on then Q503 and Q519 are turned off. 7-1. Encode • QT, DQT The CPU (IC516) transmits the encode data selected by the program.
