The cc1101 package provides a Go interface to an SPI-attached
CC1101 module.
A CC1101 module designed for 915MHz is available here.
This module comes with a 26MHz crystal, which must be changed to a 24MHz crystal by following these instructions.
The current version supports only OOK modulation (on-off keying) and a proprietary packet format (variable-length, null-terminated). Patches to support more general use are welcome.
Note that an antenna must be attached before using the module.
