Troubleshooting & Error Codes
Troubleshooting guidance for the Kenwood Model R-599S Communications Receiver includes checking for possible causes in a specific sequence and using appropriate tools like a vacuum-tube voltmeter. Key troubleshooting points include:
1. No power supply: Check for a blown fuse, defective power switch, or open-circuit near the plug.
2. Fuse blows easily: Check for defective components in the audio-frequency unit or a short-circuit to the chassis.
3. No signal reception: Investigate defective components in the AF unit, RF unit, IF unit, VFO, or coil unit, and check for poor contact in the phone jack.
4. Low sensitivity: Adjust or replace components in the AVR unit, RF unit, IF unit, VFO unit, or coil unit.
5. S meter pointer will not deflect: Adjust the IF unit or refer to low sensitivity issues.
6. Sound distortion: Check and adjust components in the AF unit, IF unit, or carrier oscillator unit.
7. RIT zero point off adjustment: Adjust the AVR unit.
8. Loss of match between marker and WWV: Adjust or replace components in the marker unit.
9. Not enough output in transceiver operation: Adjust the VFO unit or replace deteriorated components in the heterodyne oscillator circuit.
10. Deviation of transmitter or receiver frequency: Check and adjust the carrier oscillation or RIT.
Each symptom is associated with specific service points, possible causes, and remedies, such as checking circuit continuity, adjusting components, or replacing defective parts.
