And full duplex wasn't limited to autopatches "back in the day". I had several full duplex conversations with *two* other RF users that were full duplex. One person transmitted on 440, another on 2 meters and the third was on 6 meters. All three receivers were mixed onto our 440 talkback that were we all listening to. We were lids, but boy was it fun. 73's Skip WB6YMH (Funny now no one in my passenger seat ever wanted to talk on my radio ... the rubber guard on my noise canceling mic basically had to be touching your upper lip for anyone to hear you). I could turn the volume on my Micor up to the point of pain without feedback if I held the mic right.
