RasParrot: Cheap Simplex Repeater

A Cheap Simplex Repeater A type of system known as a simplex repeater uses a single transceiver and a short-duration voice recorder, which records whatever the receiver picks up for a set length of time (usually 30 seconds or less), then plays back the recording over the transmitter on the same frequency. A common name for them is a "parrot" repeater.
I'm building a system to replace atx2000 with Raspberry Pi.

UPDATE 26 Oct 2016

QParrot (old version)
Just developed a simple app QParrot (using Qt and GStreamer) that implements a mechanism VOX and audio rec/play (a parrot).

First test on Raspberry-Pi

Now I'm waiting for the sound card usb! I'll put a video on youtube!
Stay tuned!

Ciao Emanuele,
anche io sono interessato a costruire un repeater parrot per PMR con un raspberry.
Alla fine l'esperimento come e' andato? E' possibile avere il codice sorgente, in modo da smanettarci insieme?

ciao e grazie per lo spunto!
