Hirobo HI0301058 XRB SR 40.665MHz FM Receiver Crystal Replacement  [HI0301058]

XRB SR FM 40.665MHz Crystal Specification

This replacement crystal is supplied as an accessory for XRB SR FM receiver modules that use a 40.665MHz tuning element. It functions as the direct-frequency component to restore or confirm the receiver's FM channel where original crystals have degraded or where a test spare is required.

Intended for XRB SR FM receivers, always check your receiver's crystal footprint and frequency marking before attempting installation. Installation commonly requires removal of the existing crystal from the receiver PCB and soldering the replacement into the same footprint. If you are unsure about soldering very small RF components, have the replacement carried out by a technician experienced with receiver work.

Using the correct-frequency crystal helps stabilise receiver lock during setup and simplifies the troubleshooting process for reception faults. After replacement follow established receiver testing procedures to verify lock and antenna performance.
