Reliable Frequency Control with KO Propo 83664

Hobbyists restoring older radio gear or running vintage setups will find the KO Propo 83664 FM Crystal Set useful. Intended for 75MHz systems, this crystal helps keep your transmitter and receiver locked to the correct channel.

What This Crystal Brings to Your Radio

The KO Propo 83664 promotes consistent signal timing and reduces the risk of frequency drift during a session. That steadiness improves servo and throttle response compared with a worn or mismatched crystal.

Who Should Consider This Item

Choose this crystal if you operate legacy FM transmitters or maintain a collection of older models. Its simple fitment makes it suitable for both experienced tuners and hobbyists new to classic radio systems.
Remark :
Due to limited stock availability, please notice that some KO Propo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this work with my vintage transmitter?

If your transmitter accepts standard 75MHz crystals and you match the channel number on the receiver, the KO Propo 83664 will function correctly. Check the socket type before purchasing.

Are there any setup checks after fitting the crystal?

After installing the crystal, power up the radio, confirm channel selection, and perform a short range test to verify control surfaces move smoothly and without lag.

Can I replace only one crystal if the other is new?

No. You should fit matching crystals to both transmitter and receiver so they share the exact frequency. A single replacement will not establish a proper link on its own.
