Overview
The RV-75 is a synthesized remote VFO designed for use with 5-Line and 7-Line transceivers and receivers, providing high frequency control flexibility with crystal-controlled stability. It offers smooth frequency control without jumps, thanks to its 10 Hz increment synthesis and optical shaft encoder. The RV-75 features a “Variable Rate Tuning Oscillator” for versatile tuning, allowing precise frequency setting at slow rotation and rapid changes at higher speeds. It supports two fixed frequencies in addition to the tuned frequency and has a 750 kHz tuning range. The manual covers installation, operation, theory of operation, and maintenance of the RV-75.

Installation / Setup
The installation and setup of the Drake RV-75 involve several key steps:
1. Unpacking: Carefully remove the RV-75 from its shipping carton and inspect it for any damage. Retain the shipping materials for potential future use and fill out the warranty card for registration.
2. Location: Position the RV-75 for operator convenience, avoiding placement near or on top of any power supply.
3. Internal Programming: The RV-75 comes with factory preset configurations for power-up frequency and frequency change behaviors, which can be altered by adjusting jumper plugs on the internal PC cards. Options are available for both 7-LINE and 5-LINE equipment.
4. Equipment Interconnection:
– For a 7-LINE transceiver: Connect the 8-pin plug of the RV-75 to the RV-7 jack on the transceiver. Use the supplied phono cable to connect the “RIT SWITCH” jack on the RV-75 to the “ACCESSORIES” socket on the transceiver, using an adapter plug if necessary.
– For a 5-LINE transceiver: Connect the 8-pin plug from the RV-75 to the RV-5/75 jack on the transceiver. Connect the phono cable from the “RIT SWITCH” jack on the RV-75 to the “EXT. MUTE” jack on the transceiver.
These steps ensure proper setup and operation of the RV-75 with compatible transceivers and receivers.
Operation
The manual describes the operation of the RV-75, which is a synthesized remote VFO designed for use with 5-Line and 7-Line transceivers and receivers. It provides frequency control flexibility with crystal-controlled frequency stability, allowing frequency synthesis in 10 Hz increments. The RV-75 features a “Variable Rate Tuning Oscillator” that adjusts the tuning rate based on the speed of knob rotation, enabling precise frequency setting and rapid frequency changes. It also allows for two fixed frequencies in addition to the tuned frequency, programmable via rear panel switches. The RV-75 has a tuning range of 750 kHz and includes an “RIT” function for receiver offset.
