You already have lots of choices don't you ?
Trig, Funke, Garmin (other transponders are available) - what are you hoping to achieve by adding yet another ?

The rollout I have seen for WAM and ADSB is a long long way off unless there has been an acceleration in the rollout ?
besides, what does this add to Air-to-Air Electronic Conspicuity ?
So we are trying to deal with the world as it exists today, not how we would like it to be, with the mix of EC from all emitter types - this is interoperability.
In the US, the goal is to get anything under 18,000 on UAT/978Mhz, and anything that flies above 18,000ft on ADS-B/1090Mhz. This is done by a stick and carrot, a mandate, a rebate, and the offer of additional services (weather traffic re-broadcast)
So the elephant in the room is this Dave, please tell me, why have the US been so adamant to formulate this approach ?
To build a CAP1391 (basic) device is not difficult, to get through the regulatory process is costly and time consuming, the net result - another device on the market which can do the same as the others (an also ran) - so what is the net gain, over your existing choices, please tell me ?
Thx
