Replacement 40.665MHz Crystal for XRB SR FM Receivers HI0301058 - Hirobo  [HI0301058]

Service Crystal for XRB SR 40.665MHz

This replacement crystal is intended as an RC accessory for XRB SR FM receiver modules that require a 40.665MHz tuning element. It supplies the precise frequency reference used to restore or validate the receiver's FM channel when originals are degraded or when a spare is kept for bench diagnostics.

Designed for XRB SR FM receivers, confirm the receiver's crystal footprint and frequency marking prior to installation. Typical installation involves extracting the old crystal from the receiver PCB and soldering the replacement into the same pad. If you are not comfortable soldering small RF parts, have the work carried out by a technician experienced with receivers.

Fitting the correct crystal frequency aids setup and helps stabilise receiver lock, making reception issues easier to diagnose. After replacement run the usual receiver tests to confirm signal lock and antenna condition.
