[App_rpt] Recording repeater audio

Hi everyone, Does anyone know a way of recording the traffic (audio) in / out of the node and saving it as a file ( MP3 or whatever ) on the node hard drive? Something along the lines of Scanrec, which is a windows application with built in Vox and timestamps, would be ideal but I wanted to avoid having another machine involved. Anyone any ideas or thoughts on how this could be done - I should add that I'm a complete newbie! Thanks in advance for any replies. 73, Matt G4RKY
