I have a new Icom 7100 - I live across the street from the Atlantic in Maine- I bought a MFJ 1625 80-6 m window antenna - I can not receive anything but noise floor on all the HF bands - no cw, sb, rtty, beacons (there are none near me) but I attach my diamond vhf/uhf vertical and can hit a repeated 26 miles away and receive stations (up service-fine when scanning) I tested the 6 m reception with a hand held and I could receive that-the 6M band uses the same 239 ant port for 80-6 and a separate one for uhf/vhf- so by that test my receiver is OK but why no sigs on the of bands-I believe it is my location and I need better ears from an antenna--any thoughts
