I have this project to a stage where it changes the frequency on my Raspberry Pi. The next step for me is to add some antenna filtering (High Pass Filter) as my location suffers from AM broadcast interference overloading the receiver.

I simply go to the web page, type in a frequency and hit enter or submit and the radio tunes to it.

I also plan on making a "sister" project for another Raspberry Pi to receive JSON encoded transmit instructions, like WSPR and CW.
