Thanks buddrousa.
I'm interested in getting the frequency data and using the arduino to control a physical output based on what the current frequency is. For example, If the current frequency is between 144.000Mhz and 146.00Mhz then light up a blue LED. If it's between 430.000Mhz and 440.000Mhz then light up a red led.
Just interested for a small educational project i'm looking into.
