Unless you're using a synchronous detector that provides a oscillator
signal that the digital stuff can measure, there's no way. From the
point of usefulness you'd want either the equivalent BFO frequency,
or the frequency at the center of the bandpass filter. One is useful
for SSB and RTTY, the other for CW. And for AM, either one, depending
on how you use it.
