Arduino Uno + breadboard + jumper wires + CC1120 https://www.mikroe.com/ccrf-3-click
SDR# + VB-Audio virtual audio cable + Multimon-ng
Arduino tone library: https://github.com/bhagman/Tone
... works quite ok with just jumper wires connecting digital pin 4 & 5 to CC1120 GDO0 pin, DTMF tone 6 not working
CC1120
Transparent serial mode, FSK, SERIAL_RX on IOCFG0, 437.500 MHz, TX power 3 dBm.
