Inspecting firmwares of some receivers and transceivers

Some radio scanner firmwares contains lots of debugging strings and code, e.g. debug19 debug20 debug21 . C . sjis MOT TST test_control_ch 
and some are based on NORTi RTOS.

Some receiver model firmwares are probably encrypted but e.g. binwalk can show something
