2.Air traffic Control -  118–136.975 MHz  , To know the near by Airport frequency just  Google it .

3.AM , Short wave , HAM Radio comes under the range 0-30MHz which is not in the range of this device ..


Up-Converters 

Up-converters are available which is bit costly ,  Better to make our own device. 
There is one Upconverter which is very impressive & components are readily available in Element14 /aliexpress

Before that, I want to try once direct sampling method 

Normally people use transformer balun to get balanced RF input .. I haven't used that just soldered one pin . 

Soldered 

Now close the cape 

Connect to PC- add 1 Meter wire ..
