hello all. have a question pertaining to the ts-850 and the dru-2 voice module. are you able to "record" what is being heard over the airwaves, by pressing the rec1,rec2,rec3 etc, and then is it possible to have this played back over the airwaves while you have the ptt engaged, or simply have this for non-on-the-air playback? any help here as to your experience would be greatly appreciated. thank you.
