@@ -20,6 +20,14 @@ SDRPlay devices export two gain controls, IFGR and RFGR. Both of them are gain r
 RFGR is set in steps starting at 0, the maximum depends on the device and input used. Each step equals approximately 6dB of attenuation.
 IFGR is set in dB, with a minimum of 20.
 
+Some examples:
+```
+"rf_gain": "IFGR=20,RFGR=4"
+"rf_gain": "RFGR=0,IFGR=40"
