I understand all that and I got all that covered with a dual band Statux receiver. So all I really need is Out. Unless I missed something, it still looks like 1090 Out is the best way to go, since I would have to replace our venerable King transponder with Mode S anyway. Might as well get a Mode S that also squits ADS-B Out and kill two regulatory birds with one stone. (Am the builder of an Experimental, so installation costs are nil also.)
