Bob; For what its worth, there is an arrl Frequency Measuring Test (FMT) on November 20 at 0245z this maybe an interesting time to test or adjust your receiver's ability to handle usb and lsb signals using the if filter adjustments. There are some excellent displays depicting how the frequency data should look. Goto http://www.arrl.org/wiaw/fmt 73 Nick A. K1uxb
