ETOPS - you're doing more extensive flying than me, and I recognise that you've equipped yourself comprehensively to do it. I'm just exposing my thoughts on which single piece of EC kit I will go for, and since SkyEcho both emits and receives ADS-B, that is the one I choose for my needs. I appreciate everyone has different views on the subject and have been interested to hear them. PAW are clearly making great progress and I hope that somehow an integrated EC solution can be achieved.
