i just found a new DX-Patrol toy on their website, they call it QO-100 Groundstation. Other than again there is no way to toggle RX/TX by a wire or switch , the manual says some things like how easy it is to use and the like. I heard someone on QO-100 say he is using the DX-Patrol QO-100 groundstation and he can NOT receive while transmitting. There is no reference in half- or full-duplex in the manual. Anyone have info?
