Ed asked me to post this. There have been changes, and a second model of Core without PCAS or ADS-B warning (i.e., FLARM-FLARM only) which is less expensive. Cost of displays is now separate, and there are several options at various prices (Butterfly, FLARMview, LED). The new Portable has twice the transmit power of the original (20 mW vs 10mW), now equal to the Core.
