yes, a record of both would be cool to get. I want to try to apply an algo
to find the center frequency. that is your "just" part. I need to have a
sample to try.
best case szenario would be to have several of these stations within the
2MHz tuned window of that recording.

I don't know how much they usually talk and how much is silence. But one
recording with several changes would be useful.

best regards,

Andreas
