Aircraft: Disappointing. Live about 5 miles from major airport, practically in glidepath, & rarely hear the tower with the Duck (I've tried 2 or 3 different ones) even standing on front porch. I have put the telescoping antenna from the 785D on it, and once in a while can hear tower, but telescoping is a bit inconvenient -- in that if you accidentally hit it the wrong way against something .... SNAP! goes the antenna, or antenna connector probably
Trunking: Never have been able to get it to work. Manual could have been done better I think, in telling people who've never encountered Trunking how to set it up.
Close call: One thing mine does is pick freq.'s up as a reflection of sorts (i.e.: for example, a transmission on 155.000 would be picked up as 154.995, 155.000, 155.010)
