Now you can transmit ADS-B out on your Skyecho2
 

NATS have issued AIC Y 141/2019 allowing EASA aircraft (in UK) to transmit ADSB-out on portable devices, even if you already have Mode S, providing you also mail them with the info requested at the bottom of the AIC. Progress at last! Having used it to give me ADSB-in (and flarm) onto Skydemon, I know it's great, so now others will be able to see me more easily, too. Doesn't mean Mk.1 eyeball is redundant, of course.
