Sounds like you could take the output of a receiver like the IC-R8500
and feed the audio into an ADC.
The AVR one might be up to this task, depending on how finely you need
that sampled.

The usual approach with narrowband receivers is to filter, amplify,
mix, filter, and amplify (single conversion superhet)
