All voltages are measured with a high-impedance digital voltmeter and expressed in volts DC relative to ground (0V). 2. Voltages are measured with a DC input voltage of 7.50 + .02 volts DC applied to the battery connector (J301). 3. All voltages are measured in the squelched receive mode, unless otherwise indicated. 4. Voltages are identical for VHF and UHF models unless otherwise indicated. Table 11-4.

Chapter 12 UHF Schematic Diagrams, Overlays, and Parts Lists 12.1 Introduction This section provides schematic diagrams, overlays, and parts lists for the radio circuit boards and interface connections. 12.1.1 Notes For All Schematics and Circuit Boards * Component is frequency sensitive. Refer to the Electrical Parts List for value and usage. 1. Unless otherwise stated, resistance values are in ohms (K = 1000), capacitance values are in picofarads (pF) or microfarads (µF), and inductance values are in nanohenries (nH) or micro- henries (µH). 2. DC voltages are measured from point indicated to chassis ground using a Motorola DC multi- meter or equivalent. If the board has been removed from the chassis, the transmitter module mounting screws may be used for ground connection. (Note: The antenna nut bracket is not connected to ground.) Operating mode dependent voltages are followed by (RX) for receive mode, (TX) for transmit mode, (UNSQ) for unsquelched mode, etc. 3. RF voltages on VHF models are measured with a Fluke model 85 RF probe. The indicated voltages expressed in mV (RF) are DC level readings which correspond approximately 1:1 to the RF voltage level in mV rms. RF voltages in the Receiver Front End and Receiver Back End circuits are measured with an on-channel 100 mV (-7 dBm) RF signal applied to the antenna jack J140. 4. RF voltages on UHF models are measured both with a high-impedance RF voltmeter having a bandwidth in excess of 500 MHz (levels are expressed in dBm) and with a Fluke model 85 RF probe [levels are expressed in mV (RF)]. These indicated voltages are DC level readings which correspond approximately 1:1 to the RF voltage level in mV rms, and are only approxi- mate for UHF frequency measurements. RF voltages in the Receiver Front End and Receiver Back End circuits are measured with an on-channel 100 mV (-7 dBm) RF signal applied to the antenna jack J140. 5. Audio voltages are measured with a high-impedance AC rms voltmeter. The indicated volt- ages are expressed in mV rms. Receive mode voltages are followed by (RX) and are mea- sured with an on-channel signal with 1 kHz modulation at 60% deviation (3 kHz for 25 kHz channels, or 1.5 kHz for 12.5 kHz channels). Transmit mode voltages are followed by (TX) and are measured with a 1 kHz, 10 mV rms signal present at the external microphone input (accessory connector J471 pin 4 hot and pin 7 ground). 6. Reference Designators are assigned in the following manner: Ref.
