Great radios. Have two of them. Bought the 2nd one just to have a spare. Works great on 10 & 11 meters.
This morning I talked to forum member Farmer Brown (Bill) in Texarkana Arkansas. He was on his AT-6666 and I was on one of mine.
All of the Quad 6's that I've heard on sideband sound very good IMO. To me they sound like they should cost more than they do. Shoulda woulda coulda bought one.......
