Being new to S/V and it's features, I am trying to get up to speed on the A/P and the adsb. I have noticed that the adsb service is very intermittent. I can leave my home airport, have no adsb and fly to a nearby destination, land and shut down. I can then depart with adsb and have it all the way home. The other fliers in my group will have service with their adsb in only receivers with no problems. I am wondering if the adsb out feature is not working. Anyone else experienced this? BTW, there is lots of atc around here. I am between Wash. and Philly.
