The frequency 7812.5 listed under Key West, FL is actually 7811.

No, it's really 7812.5. Shortwave and amateur radios are calibrated
differently than commercial, marine and miltitary ones.

You are used to setting USB freqencies to the carrier (bottom) which is at
7811. The frequency listed is the CENTER frequency which is what their
radio is calibrated to.

Look up 60 meter ham band frequencies for an explanation.
