    TR-800 Service Manual Circuit Description Repeater Communication Interface & Display Unit Setup/Knockdown (U0107D, Q0101, Q0103, Q0106, Q0107 and Q0108): The setup/knockdown mode at power-up can be configured via the HR-800 programming software. The electronic switches, Q0106 and Q0108, cause the setup/knockdown action by applying or removing voltage at the ignition control, pin15, of “J0102-Main”.
  • Page 40 TR-800 Service Manual When the reverse key-up function is enabled, as in the bi-directional repeater configuration, S0101-8 must be on. Q0116 is a DC amplifier (buffer) for the Rx carrier signal from pin6 of “J0102-Main”. An active low state at the input of the NAND gate U0107A, one quarter of a MC14011B, will be conversed to a high state to drive the buffer for the Rx carrier signal.

The reference voltage at the positive input of U0205B-5 is increased such that the battery voltage must rise above 12Vdc before relay KR01 will reactivate and place the TR-800 back on the battery power. This latching action is used to prevent excessively deep discharging of the battery.

    The following procedure assumes that the duplexer is applied and the radios should be connected to the proper ports of the duplexer with the RF coaxial cables provided in the TR-800 kit. The duplexer should not be mounted on the bracket and the tuning screws of the duplexer (on the other side of the cavities, opposite to the RF connectors) should be accessible.
