For the purpose of this configuration I expect your Raspberry pi to be connected to the internet. How will this repeater work. This configuration was done with the latest Raspbian Os for Raspberry Pi downloaded from here I used my original Raspberry Pi B+ and also repeated this on a Banana Pi as I need a hard drive to compile gnuradio for later SDR use. I will be using a rtl dongle to receive my input signal on 70cm frequency configurable on the amateur 2m or 70cm band. The receiver signal will then be demodulated and re transmitted with a DSP Library simulating a FM Signal using a GPIO pin on the Raspberry as an transmitter.”
