+    Especially when switching SDK build revisions, like when switching between regular builds and "beta" or "alt.WiFi" builds.
+    Another reason to clear the RF calibration is when initial RF calibration was done with a different power supply, or when WiFi performs badly after placing the ESP in a different enclosure which may de-tune the antenna.
