Installation / Setup
The installation highlights for the Kenwood TK-7100 VHF FM Transceiver include several key steps and considerations:
1. Pre-Installation Checkout: Before installation, check the operation of the receiver and transmitter for proper functionality. This includes testing with all cabling and accessories connected as they will be in the final setup. Verify transmitter frequency, deviation, power output, receiver sensitivity, squelch operation, audio output, and signaling equipment operation.
2. Planning the Installation: Inspect the vehicle to determine the mounting locations for the radio antenna and accessories. Plan cable runs to avoid pinching or crushing and ensure the installation prevents overheating.
3. Antenna Placement: The preferred antenna location is the center of a large, flat conductive area, usually the roof center. If mounted on the trunk lid, bond it to the vehicle chassis using ground straps.
4. Radio Mounting: Use the universal mount bracket to mount the radio securely. Ensure the mounting surface can support the radio’s weight and allow sufficient space for air cooling. Position the radio for easy access to controls.
5. DC Power and Wiring: The radio should be installed in negative ground electrical systems only. Connect the positive power lead directly to the vehicle battery’s positive terminal and the ground lead to the battery’s negative terminal. Ensure any extended cable is sufficient for the current demand.
6. Control Stations: For control stations, select a radio location close to the antenna cable entry point and ensure adequate air flow for cooling.
These steps are crucial for ensuring a safe and efficient installation of the TK-7100 transceiver.
