The Drake SCHEMATICS manual provides detailed instructions for setting up and operating the SSR-1 communications receiver, including guidance on tuning, mode selection, and power supply options. It also offers troubleshooting tips for common issues, such as signal interference and power source selection, to ensure optimal performance.
Manual Overview
The Drake SCHEMATICS manual for the SSR-1 Communications Receiver provides detailed guidance for troubleshooting, diagnostics, calibration, and board-level adjustments. Troubleshooting begins with checking the power source, ensuring the correct voltage is selected via the rear panel switch, and verifying connections at the antenna terminal strip. Error codes are not explicitly detailed, but the manual suggests using the signal meter to assess RF input levels for diagnostics. Calibration involves using the manual preselector for optimal sensitivity and interference rejection, and the clarify control for fine frequency adjustments, especially for SSB and CW signals. Board-level guidance includes ensuring solid-state circuitry is intact and checking the internal battery or external power connections. The manual emphasizes the importance of using the appropriate mode and band selectors for accurate reception, and advises consulting additional resources like the “World Radio TV Handbook” for enhanced operation.
Quick Issues Covered
- Diagnose power-up failures with external DC or AC power sources.
- Calibrate frequency using the MHz and kHz tuning controls.
- Trace circuits using detailed schematics for component-level troubleshooting.
Overview
The SSR-1 Communications Receiver by R. L. Drake Company is designed for precision tuning over the short wave spectrum from 0.5 to 30 MHz, capable of receiving AM, CW, and SSB signals. It features a synthesized/drift cancelling system with 30 tunable ranges, ensuring frequency stability necessary for SSB operation. The receiver includes separate detectors for optimal performance in SSB and AM modes, narrow and wide band selectivity, a built-in telescopic antenna, and a manual tuned preselector for maximum sensitivity and interference rejection. It operates efficiently from an internal battery or external power sources, offering ease of operation and quality reception. The manual covers the receiver’s features, controls, and operating procedures, providing guidance for both casual and serious radio listeners.
Specifications
The SSR-1 Receiver provides precision tuning over the short wave spectrum of 0.5 to 30 MHz. It has a synthesized/drift cancelling 1st mixer injection system with 30 tunable ranges derived from a single 10 MHz crystal oscillator. The receiver includes separate detectors for SSB and AM signals, narrow band selectivity for SSB, and wide band selectivity for AM. It features a built-in telescopic antenna and can be connected to an external antenna. The receiver uses solid state circuitry and can operate from a built-in battery supply or an external DC or AC power source.
Controls & Indicators
PHONE JACK: For earphone reception or external speaker (8 ohms). Insertion of phones or speaker jack disconnects internal speaker.
OFF – VOLUME: Turns radio on and off and adjusts audio output level.
BAND: Selects the proper range of received frequency.
MODE: Selects mode of reception, AM (amplitude modulation), USB (upper single side band), and LSB (lower single side band). CW (continuous wave) may be received on either USB or LSB position. The mode selector selects the proper detector (product detector for SSB and diode detector for AM) and IF selectivity filter.
CLARIFY: Provides ultra fine frequency adjustment (approximately +3 kHz range). This control is used primarily on SSB and CW signals for setting the pitch or sound accurately after the station has been roughly tuned in. It should be in the center position before any tuning is commenced.
PILOT LAMP SWITCH: On AC operation the pilot lamps are always lighted. The pilot lamps are normally extinguished on battery operation to conserve battery life. Pushing this momentary action switch turns on the pilot lamps.
TUNING: Tunes the MHz range of the received frequency. This control tunes the smaller inner dial (11) and is adjusted for the center of the desired MHz range.
SIGNAL METER: Indicates relative RF input signal level.
PRE-SELECTOR: Adjusts receiver RF tuned circuits for proper reception of signal. This control is tuned for maximum signal or noise at the selected frequency.
kHz: Tunes the kHz range of the receiver. This control turns the large outer dial (12) and is adjusted for the proper frequency as displayed on the graduations. This dial has a graduated scale from 000 to 1000 and is read as 0 to 1000 kHz or .000 to 1.000 MHz.
FREQUENCY DISPLAY: Indicates tuned frequency as explained in paragraph 7 and 10. The inner dial indicates MHz range and the outer dial indicates kHz reading. As an example: 5.750 MHz.
