VERY IMPORTANT INFORMATION:

Before purchasing it is essential to check that your existing radio gear is compatible with these 27mhz AM crystals:

For example, 27mhz AM crystals will only work with 27mhz AM radio gear, 40mhz FM will only work with 40mhz FM radio gear etc. So if your transmitter is 27mhz AM, it will only work with 27mhz AM crystals and a 27mhz AM receiver. You cannot mix AM with FM and you cannot mix 27mhz with 40mhz. If in any doubt, please ask before purchasing.

Used tested working transmitter/receiver crystals - supplied as a pair, without holders. We have many hundreds of these so you are unlikely to receive any of the ones shown in the pictures, all are in used, tested working condition.

A random frequency will be sent (for example you may receive crystals with a frequency of 27.195) and if you order more than one pair we will endeavour to send different frequencies (subject to availability of course). However please feel free to contact us before buying if you need a specific frequency or to check availability of multiple frequencies if buying more than one pair. Please note that 26.995 is classed as a 27mhz crystal.

Although each pair have been tested and are working perfectly, on very rare occasions some radio gear can be fussy about the type of crystals used with them (e.g. Sanwa). In the unlikely event that you receive a pair that don't work with your particular radio gear they can be returned to us for a refund.
