Interfacing Rpi or similar for VHF PTT using rtl-sdr

Post by Eddie87 » Wed Jan 15, 2020 1:15 pm

Hi, I am starting on a project where I need to interface Raspberry pi or any other small microcontroller board or small pc board so that it can recieve PTT signals from a VHF radio of any model with the rtl-sdr module.

the idea is to use the VHF to send PTT signals through rtl-sdr on the raspberry pi which can then control some lights/LEDs through a relay circuit.

Is there any tips on how to do this?
What about previous projects? Has anybody heard about this before?

Thanks
