The manual provides installation instructions for the carrier operated relay kit in the MR 50/60 and FM 150/160 series equipment, including a schematic diagram for setup and guidelines for adjusting the relay's sensitivity. It also covers troubleshooting by explaining the theory of operation and offering a modification for automatic hold and manual reset, ensuring the system functions correctly in various conditions.
Manual Overview
The Hammarlund Carrier Operated Relay Kit, part number PL 538260-G1, is designed for installation in the MR 50/60 and FM 150/160 series equipment. It is not recommended for mobile service due to voltage variations. Installation requires referencing the provided schematic diagram. The relay operates by detecting changes in thermal noise amplified in the FM receiver, which affects the DC voltage at the grid of the pentode section of the 6BBR8BA tube. Adjustments are made using the R4 control to set the relay’s sensitivity. The most sensitive setting is achieved by adjusting R4 until the relay is just de-energized with no signal input. For reduced sensitivity, apply a strong signal and adjust R4 until the relay operates. An automatic hold and manual reset modification allows the call lamp to remain lit after signal actuation, with reset achieved via switch S102. The kit includes a detailed parts list and schematic for reference.
Quick Issues Covered
- Adjust R4 for relay sensitivity in MR 50/60, FM 150/160.
- Carrier Operated Relay schematic aids in circuit tracing.
- Avoid mobile use due to voltage variations in MR 50/60 series.
