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 https://www.raspberrypi.org/downloads/ 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.”
