2307z 124.250 CAMBER 0783 wkg ZBW. Took off from Bangor heading East. He told ZBW about the new CAMBER callsign for civil contract flights. Got a nice audio clip of the explanation. 2312z 123.400 CAMBER 0783 switching to Moncton Center, climbing from 18.7 for 280. Most likely heading across the pond. Ed Langworthy Gray, ME
