Our radio modules are available on several frequencies from 27MHz up to 918MHz, covering licence exempted and licensed frequencies around the world as well as frequencies reserved for specific applications such as AIS and APRS.

Other single frequency module variants can be supplied to individual customer requirements. However these are subject to minimum order quantity (due to crystal / filter MOQ) and at least 14 weeks lead time (12 weeks for custom crystal/filter + 2 weeks development).
For a low volume and prototype requirements, we would recommend our multi channel products as they can easily be customised to operate on any frequencies over 27MHz and do not require MOQ or long lead time.
Please consult our Sales Department for further information.
