RANS6ANDREW a good question. I think a PAW and TRIG transponder with ADS-B would be the answer. That would give you mode C/S ADS-B and Flarm, with OGN ground station support, note a Flarm reciever can be connected directly into a PAW but costs. With Trig transponders the GPS out of the PAW can be legally input for the ADS-B out. The PAW can be connect into the audio for traffic and feed a stand alone display and wifi to the IPAD with SkyDemon at the same time. The PAW and TRG would be the best and give you max awareness and conspicuousness. Plus I think you may be able to get a rebate for the TRIG.
