The manual for Drake 2 covers the setup and operation of both the receiver and transmitter, detailing the functions of various sections such as the emitter follower, amplifier stages, and voltage regulators. It also provides troubleshooting information by explaining the roles of different components like the AVC amplifier and deviation pot in the system.
Manual Overview
The Drake 2 manual provides detailed guidance for troubleshooting, diagnostics, and calibration of the device. For the receiver, IC101 is divided into five sections. Section I functions as an emitter follower driving the meter amplifier (Q109) and interacts with Sections II and III. Section II acts as an amplifier driving Section IV, while Section III serves as the AVC amplifier for the receiver’s front end. Section IV is a limiter, and Section V is a voltage regulator for Sections I, II, and III, but not for Section IV. For the transmitter, IC201 is organized differently. Section I is a microphone amplifier that feeds into Section IV, which is an amplifier stage whose output goes through a deviation potentiometer to Section II. Section II is another amplifier stage that feeds the modulator. Section III is not utilized, and Section V regulates Sections I and II. The manual emphasizes understanding these sections for effective troubleshooting and adjustments at the board level.
Quick Issues Covered
- Diagnose issues with IC101 voltage regulation in Sections I-III.
- Calibrate transmitter deviation using Section IV and deviation pot.
- Troubleshoot power-up failures in IC201 Section V regulator.
