 You'll need to edit some code and recompile if you want to break outside of the officially supported frequencies. ([Hint here...](https://github.com/flipperdevices/flipperzero-firmware/pull/1287/files))
 
+# Modulation (AM/FM)

+AM650 and FM650 modulation tries to cover more range of frequencies at the cost of less pickup distance.<br>
+AM270 and FM270 modulation offer a more narrow range, but have a cleaner pickup and slightly better distance.
