Hi Igor,
your Op-32 transmissions are nice, and the coherent carrier is well visible in 477 uHz resolution on the DL0AO and DF6NM grabbers. Only there is sometimes a slow drift: some nights the frequency creeps upwards, sometimes down, perhaps depending on temperature changes. Two nights ago it was almost stable, helping to achieve many successful opds detections. Sometimes you also come near a Chayka line on 137493.75 Hz.
