Hirobo HI0301058 XRB SR receiver crystal 40.665MHz FM replacement  [HI0301058]

XRB SR receiver crystal 40.665MHz

This replacement crystal is intended as an RC-scale accessory for XRB SR FM receiver modules that use a 40.665MHz tuning element. It serves as a direct-frequency component to restore or verify the receiver's FM channel when original crystals are worn, damaged, or when a spare is required for bench testing.

Compatibility is focused on XRB SR FM receivers; confirm your receiver's crystal footprint and frequency marking before installation. Installation typically involves removing the old crystal from the receiver PCB and soldering the replacement in the same footprint. If you are not comfortable with soldering small RF components, seek assistance from a technician experienced with receiver work.

During setup and tuning, a correct-frequency crystal helps stabilise receiver lock and simplifies troubleshooting of reception issues. Use standard receiver testing procedures to verify signal lock and antenna performance after replacement.
