Short Description Many Asian borne handheld transceivers will have the menu option for a roger beep and many of them like baofengs and radtels will have a option for a roger beep called "TONE1200" and this is to mimic the sounds you would hear on analog police networks. But the thing is most radios fail to do that and it sounds more like a MPT1327 packet.
