I was trying to listen to the local AM station on 1400 Khz to catch the end of a College football game. It did not appear that the 6300 covered the complete AM broadcast band. Is this correct? If you chose 160m it would go to approx 1600 Khz and if you chose band "630" you can get 550 to 670 Khz. Is this correct that the 6000 series doesn't cover the full AM broadcast band or am I do I have something set incorrect?
