FM Modulation
The Bird Site Analyzer uses FM modulation to improve its immunity to interfer-
ing signals. Under certain circumstances, such as while making cable loss or
other high reflection measurements with long cables, FM modulation may
reduce signal quality. In that case, the modulation should be turned off.

FM modulation is on by default, and will be turned back on whenever
the unit is reset to defaults.

FM modulation is automatically turned off while the unit is in Cable
Loss Mode and returned to its previous state on exiting Cable Loss
Mode.

Saving a setup saves the status of the FM modulation.
