A series of Python scripts experimenting with alternative tools for tuning Software Defined Radio (SDR) through gqrx
Coorelates a top and bottom tuning frequency with a high and low midi key, dividing the frequencies evenly among the keys in between. This allows you to tune the radio with a midi controller.
Uses a low frequency oscillator to tune the radio frequency in a constantly changing manner. Adjusting the frequency of the LFO affects how fast the tuner moves up and down. Adjusting the LFO depth affects how far up and down the frequencies go.
For Raspberry Pi. Reads an encoder from GPIO pins to tune the radio.
